The main purpose of the electronic special gas cabinet is to safely transport special gas; No external pollution and fine particles in the gas in the filter through the filter. The main requirements of the main requirements are safety, and the main risk of special gas cylinders is that there is a harmful gas in the case of the cylindrical cylinder valve without being killed or the pipeline; (2) After converting the cylinder joint after the bottle (the pig tail lineage joint ) Not connected, causing the gas overflow when opening the bottle. The following is detailed by Woy Fei Technology, with the safety requirements for special air cabinet cylinders.
Special gas cabinet cylinder safety operation procedures:
1. Non-experimental persons are strictly prohibited from contact with gas cylinders and related valves.
2. It is strictly forbidden to hit the impact during operation, pay attention to the pressure gauge reading, regularly check the valve and pipeline to ensure no leakage.
3. When replacing, make sure the new gas bottle is clear and complete; during the handling process, it should be lightly put it. Only when the gas cylinder is stable, you can let go.
4. The cylinder should be stored in a cool, dry, away from the heat source, and place the ground of the gas cylinder must be flat, the safety cap on the cylinder should be tightened to protect the valve. Do not turn it.
5. When using a nitrogen bottle, the bottle valve is used first, and then the decompression adjustment screw slowly rotates the gas out. Use the PP gas bottle valve, and turn out the pressure in the pressure reducer, then remove the decompression air conditioner screw.
Special gas cabinet cylinder storage safety requirements:
1. It should be placed in a special warehouse storage, and the gas cylinder warehouse should comply with the relevant provisions of the "Building Design Fire Prevention Specification";
2. There is no gutter in the warehouse, dark road, strictly forbidden to open fire and other heat sources, in the warehouse should ventilate, dry, avoid direct sunlight;
3. Control the temperature in the warehouse, specify the storage period;
4. It is strictly forbidden to heating the gas cylinder with a heat source of more than 40 ° C;
5. The gas cylinder should be properly equipped with a bottle cap. When putting the place, it should be properly fixed; when it is placed, the head is in the same direction;
6. Confirm the steel printing and color tag of the gas cylinder, confirming gas cylinders that do not meet the safety technical requirements;
7. Empty bottles are inspected, and the gas in the bottle is not exhausted, and there must be remaining pressure; the remaining pressure of the gas cylinder should not be less than 0.05 MPa.
8. Cylinder bottle shoulders have the specific time of the next test, which can be put down this time. It is time to send to specialized testing mechanism tests to be bottle. It is generally two years to detect once.
9. The empty bottle should be placed separately and have obvious signs; with toxic gas cylinders and bottle gas can cause combustion, explosion, gas cylinders that produce poisons, and store them in the vicinity of gas utensils or Fire extinguishing equipment;
The special gas cabinet mainly used special gases, such as flammable, explosive, highly toxic, etc., mainly for semiconductors and LEDs.
