AFKLOK pressure regulators have attracted a great deal of attention as important control devices in the industrial and civil sectors. AFKLOK pressure regulator, as the name suggests, is a device used to regulate the pressure of a fluid or gas. It usually consists of a sensing element, a control mechanism and a regulating element. The sensing element is sensitive to changes in pressure within the system. When the pressure exceeds or falls below the preset range, the change is quickly transmitted to the control organisation. The control unit acts as the regulator's "brain", analysing and judging the pressure information it senses. It then directs the regulating element to take the appropriate action. In terms of regulating elements, common ones include springs, diaphragms or pistons. Take spring-type pressure regulator as an example, when the system pressure rises, the force acting on the diaphragm overcomes the elasticity of the spring, so that the valve opening decreases, thus reducing the flow of fluid or gas and realising the lowering of pressure; on the contrary, when the system pressure decreases, the elasticity of the spring pushes the diaphragm, so that the valve opening increases and the flow rate is increased, so as to achieve the effect of boosting the pressure.   AFKLOK pressure regulators play a key role in many fields. In industrial production, it ensures that all kinds of equipment operate under stable pressure, improving production efficiency and product quality; in civil fields, such as gas supply systems, it guarantees the safety and stability of residents using gas.   With the continuous progress of science and technology, the working principle of AFKLOK pressure regulator is also being optimised and innovated to meet the needs of more complex and diversified application scenarios. In the future, we have reason to believe that AFKLOK pressure regulators will play a more important role in ensuring the stable operation of the system.

In today's era of rapid technological and industrial development, AFKLOK pressure regulators are playing an indispensable role as key control components in a wide range of applications.   In the energy sector, pressure regulators play an important role in the extraction, transport and storage of oil and gas. It can accurately control the pressure inside the pipeline to ensure the safe and efficient delivery of oil and gas resources, reduce the risk of leakage and guarantee the stability of energy supply. In the medical industry, AFKLOK pressure regulators ensure the proper functioning of medical equipment. For example, in the oxygen supply system, it can stably regulate the oxygen pressure to provide patients with appropriate oxygen intake conditions; in anaesthesia equipment, it accurately controls the gas pressure to ensure anaesthesia effect and patient safety during surgery. In the manufacturing industry, AFKLOK pressure regulators are used in all kinds of production processes. Whether it's pneumatic tools in automotive manufacturing or gas-shielded welding in electronic equipment production, it ensures constant working pressure and improves product quality and productivity. In addition, AFKLOK pressure regulators have important applications in the aerospace industry. In the aircraft fuel system and hydraulic system, it can adapt to different flight altitudes and working conditions, to ensure stable system pressure, to ensure flight safety.   In the field of agriculture, modern greenhouses and irrigation systems also use AFKLOK pressure regulators to achieve precise control of water and gas, optimise the growing environment of crops and improve the efficiency of agricultural production. It can be said that AFKLOK pressure regulator application fields continue to expand and deepen, for the development of various industries to provide strong support, promote the progress and development of society.

Valve selection is an important part of proper design and maintenance practices for piping and instrumentation systems. If the correct valves are not selected for a particular application, the user unit may be exposed to inappropriate or inferior special gas system performance, longer downtime, and unavoidable safety risks. Valves are usually selected during the initial stages of a special gas control system design, and throughout the system's life cycle, technicians typically follow specifications to better valves and most other components using the same types of components already present in the system.   Selecting the correct valves from the outset is therefore very important to help user units avoid premature valve replacement later on.   How to make the right choice?   The technical and purchasing staff at the customer's facility can follow the STAMPED method, which takes into account size, temperature, application, media, pressure, ends or fittings, and delivery.   Full consideration of each of these operating conditions can guide the selection of the correct valve to be used in the speciality gas system.   The following is a detailed description of how STAMPED is applied to special gas system design: 01 S - Size   The size of a valve determines its flow rate and needs to correspond to the desired or required flow rate of the system. The flow coefficient (Cv) of a valve expresses the relationship between the pressure drop across the valve and the corresponding flow rate.   Valve design factors that affect Cv include the size and geometry of the flow path; the size of the valve's orifice affects the fluid flow through it. The larger the orifice, the greater the potential flow rate. The orifices of different types of valves can vary greatly; for example, a ball valve will provide little resistance to flow, but a needle valve will restrict or slow down the flow rate. These should be considerations in your selection process.   02 T - Temperature   The operating temperature of the valve will help control the temperature of the media in the system, and the ambient operating temperature of the surrounding environment. It is important to note whether the temperature of the valve will remain constant or change frequently, and these conditions may affect valve selection or the frequency with which preventive maintenance needs to be performed.   Consider temperature fluctuations that may cause sealing materials to expand and contract. In addition, metal parts may lose strength at high temperatures, thereby reducing pressure ratings, and it is necessary to ensure that the valve has been thoroughly tested under extreme conditions.   03 A - Application   Consider what the valve is required to do in a system, is it required to start or stop the flow of media? Regulate flow levels? Control flow direction? Protect the special gas system from overpressure?   Having a clear idea of the application of the valve in the system will guide you to a clearer choice of valve type. Take a simple bi-directional ball valve as an example, whilst some ball valves may offer throttling, most should not be used for throttling or regulating flow, but should be used in either fully open or fully closed condition, if your need is to throttling or regulating the flow, a needle valve or metering valve may be a better choice.   04 M - Medium   or to regulate flow, a needle valve or metering valve may be a better choice. Careful consideration should also be given to the fluid medium within the system when trying to select the correct valve with the proper material composition.   Ensure that the system media is compatible with the materials that make up the valve body, seat, and stem shear, as well as the softer materials of the gas. Failure to do so may result in corrosion, embrittlement or cracking, which can pose a safety risk and costly production and safety problems for the user unit.   As with temperature, the location where the valve is to be used should also be considered. Is it operating in a climate-controlled environment, for example inside a plant or in a heated instrument enclosure? Or is it used outdoors, exposed to climatic factors such as sunlight, rain, snow and temperature fluctuations over a long period of time? Valves and their components are available in a wide range of materials. Remember to select the appropriate valve in relation to the above environmental and climatic factors in order to maximise the service life and functionality of the valve.   05 P - Pressure   Pressure is another important consideration when selecting a valve. There are two types of pressure: 1. Operating pressure: the normal working pressure in the system. 2. Design pressure: the maximum pressure limit of the valve; never exceed the design pressure of any Special Gas system component except under controlled test conditions.   The pressure limit of a special gas system is based on its lowest rated component - bear this in mind when selecting a valve. The pressure and temperature of the process medium have a significant effect on component performance. The valves you select need to withstand pressure and operate over a wide range of temperatures and pressures when required. Design, material selection and validation are all critical aspects of valve performance. It is also important to remember that pressure and temperature have a significant effect on each other.   06 E - End connections   Valves come with a variety of different end connections. These may be integral tube fittings, pipe threads, pipe flanges, weld ends etc. Although not traditionally associated with the construction of a valve, the choice of end connections is critical to the overall construction of the valve and its ability to maintain a sealed system. Ensuring that the end connections are suitable for the system pressure and temperature, and are of the right size and material, the correct end connections can simplify installation and avoid additional leak points.   07 D - Delivery Finally, having considered all of the above factors and selected the right valve for your application, as with any other factor, on-time delivery and reliable supply is important to keep the Special Gas system running and efficient. As a final step in the STAMPED approach, there is a need to consider the strength of the supplier, their ability to meet the demand when you need the part, and their ability to work with you to understand the needs of your system.   The above is the STAMPDE method compiled by WOFLY (AFKLOK), we believe that through the above steps, the user unit will have a better understanding of how to choose the right valve. If you have any questions, WOFLY (AFKLOK) is also very welcome to your inquiries. WOFLY (AFKLOK) in the field of special gas applications for thirteen years, the gas application industry is very familiar with the relevant processes, and has a strong, stable supply chain and construction technology team, these are our strong backing, so that we have the strength and determination to provide the best quality, the most secure full set of gas applications for the user units.

The main purpose of the special gases application control system is to provide high-purity electronic special gases for the safe supply of industrial process end-use points. The entire system consists of a number of modules covering the entire flow path from the gas source to the gas manifold to the end-use point.   There are two main requirements for the use of speciality gases in user units. One of the main requirements is to ensure pressure and purity, which is achieved in the speciality gas control system by means of a pressure regulator, and purity by means of a high degree of airtightness of the system to avoid external contamination and filtering of particles in the gas by means of a filter.   The second main requirement is safety, flammable and explosive gases, toxic gases, corrosive gases and other dangerous gases are special gases. Therefore, the special gas system engineering danger is high, in the design, installation and use of operation need to consider the supporting safety facilities.   Today we mainly know, in the special gas application control system has what safety linkage equipment?   01 Emergency stop button   The emergency stop button is used to remotely close the pneumatic valves of the gas supply equipment on site.   When the leakage alarm reaches the second alarm, the staff can carry out remote manual shutdown operation on the gas supply equipment, and close the pneumatic valve of the gas supply equipment in time.   02 Gas Detector The gas detector is mainly used for continuous and uninterrupted sampling and analysis of the gas supply equipment to determine whether there is gas leakage from the gas supply equipment.   When the detector works normally, the sampling flow rate of the detector reaches 500mL/min.   For heated gas, it is necessary to install gas heating unit to achieve auxiliary heating effect.   03 Alarm light Alarm indicator is mainly used to indicate the alarm situation on site, which is composed of alarm light and buzzer.   The alarm indicator is generally a tower-type alarm light. When the leakage alarm reaches one alarm line, the alarm light will be yellow and the buzzer will start; when the leakage alarm reaches two alarm lines, the alarm light will be red and the buzzer will start.   The alarm light requires 24VDC power, and the buzzer needs to sound at 80dB or higher.   04 Sprinkler head Glass ball sprinkler head of the glass ball, filled with a high coefficient of thermal expansion of the organic solution, the fire, the organic solution temperature increases and expansion, until the glass body is broken, the seals lose support by the water flow, so that the beginning of the spray water.   The main role of the shower head in the gas cabinet is to cool down the cylinder to avoid secondary accidents.   05 UV/IR Flame Detector   UV/IR can detect both UV and IR light segments in the flame. When both UV and IR light segments are detected, the detector sends a signal to the control system and triggers the linkage.   Since the flame must contain both UV and IR light segments, the UV/IR detector can effectively avoid false alarms caused by other separate UV or IR sources.   06 Overcurrent protection switch (EFS) The overcurrent protection switch senses abnormal changes in gas flow. When the gas flow rate is greater or less than the set point, the overcurrent protection switch signals the control system and triggers the linkage. The set point of the overcurrent protection switch cannot be adjusted on site.   07 Negative Pressure Gauge / Negative Pressure Switch   Negative pressure gauge/negative pressure can measure the negative pressure value inside the gas cabinet to ensure that the air extraction volume of the equipment meets the design requirements and to improve operational safety.   Negative pressure switch can send a signal to the control system when the negative pressure value in the equipment is lower than the set value, and trigger the linkage.   08 PLC control   PLC control system has a strong reliability, all the signals will be transmitted to the PLC system, after it is processed and transmitted to the human-machine interface, PLC can complete the signal transmission and control of all terminal equipment.

With the booming development of the semiconductor industry, higher requirements have been put forward for its supporting projects. The supply of special gases has not formed an effective system, and the problems of messy cylinders, chaotic management and mixing of incompatible gases are more serious, which greatly affects the safety of gas consumption. So how to deal with the gas tail gas in the special gas pipeline project? Today the staff of Shenzhen Wofei Technology Co:   Special gas tail gas treatment   Special gases on health and the environment will produce great harm, how to deal with special gas tail gas, with what equipment, here will be an in-depth introduction. Status of speciality gas tail gases   Tail gas inevitably exists as a derivative of the special gas system. In the past, in many colleges and universities, due to the laboratory gas consumption is not large, the owner of the construction unit is not fully aware of the tail gas emission problem, with more semiconductor factories springing up, the production of special gas tail gas emission more and more attention. Then how to discharge, how to discharge has become a problem in front of many users.   The treatment method of the tail gas emission treatment device of the special gas system:   The type of tail gas treatment device should be selected according to the characteristics of the special gas in the exhaust to be treated, and incompatible special gases should be separately set up tail gas treatment device;.   Tail gas treatment device should be arranged close to GR, GC and other special gas equipment.   The tail gas treatment method of special gases shall adopt dry treatment adsorption, wet scrubbing, heating decomposition treatment, combustion treatment, plasma decomposition treatment, dilution treatment and the combination of the above methods.

I don't know if you are familiar with pressure piping, pressure piping from a broad understanding, pressure piping refers to all the pipelines subject to internal or external pressure, regardless of the medium in the pipe. There are many kinds of classification of pressure piping, in order to be able to let you have a more in-depth understanding of pressure piping, the following staff of Wofly technology to introduce how to classify pressure piping by pressure: Pressure piping according to the classification of pressure, pressure piping is divided into low-pressure, medium-pressure, high-pressure, as well as ultra-high-pressure, the following to tell you about these pressure piping according to the pressure classification of the pressure range:　 1. low pressure pipework pressure: 0　　 2. medium pressure pipeline engineering pressure: 1.6　　 3. High-pressure pipeline engineering pressure: 10MPa　　 4, ultra-high pressure pipeline engineering pressure: 10-20MPa.　　 Pressure piping by pressure how to classify the first for you here, pressure piping operations are generally outdoors, laying methods of overhead, along the ground, buried, and even often high altitude, poor environmental conditions, quality control requirements are high. As the quality control link is interlocking, organic combination, a link slightly negligent, resulting in quality problems.

In the process of gas line installation, pressure reducer is to be used in the instrument, its role is to adjust, the inlet pressure will be reduced to a certain need for the export pressure, and rely on the medium’s own energy, so that the export pressure is automatically maintained at a stable valve. Its differential pressure is a certain limit, then the pressure difference of the pressure reducer is too large should be how to solve it, the following Wofei gas line installation manufacturers will be introduced to you. Pressure reducers are rated for leakage at different pressures. General leakage will not exceed 3%, if the pressure difference between the pressure reducer is too large this will result in the pilot valve is automatically top open state, can not ensure that the back end of the pressure stability and accurate control. When this situation occurs, the back-end pressure will lead to the pilot valve diaphragm and the corresponding action of the adjusting spring to frequent automatic corrections, resulting in the pilot valve must be adjusted too often, so the pilot valve is particularly easy to be worn out. 　　Then how to solve it such as working conditions in the normal flow rate of 3000kg / h, the inlet pressure of 15BarG, set the pressure of 3BarG, then solve the problem with the following scheme: differential pressure with two pressure reducing valves in series with the pressure reducing station. The first pressure reducing valve will be DN40, set pressure is set to 8bar, from 15 to 8bar, the flow rate is 3300kg/h, the second pressure reducing valve will be DN50, set to 3bar, the pressure will be reduced from 8 to 3bar, the flow rate is 3030kg/h. 　　Each pressure reducer from the back end of the feedback conduit, copper pipe, the distance to 15 times the diameter of the pipe or 1 metre is appropriate, the pressure gauge is installed in the conduit at the back end of the spacing between the two pressure reducers at least 30 times the diameter of the pipe or more. If the installation location is not enough to require the distance between the two pressure reducing valves, each pressure reducing valve upstream and downstream are required to install a separate shut-off valve. If the above two situations occur at the same time, both large flow changes, and large differential pressure, then the series-parallel combination of pressure reducing station.
