The safety valve plays a safety protection role in the whole air compressor equipment. When the pressure of the equipment exceeds the rated value, open the safety valve to discharge part of the gas out of the equipment so that the pressure of the equipment is within the allowable range of operation, to avoid the accident of the air compressor due to high pressure. Safety valves are also called relief valves, and there are many kinds of safety valves according to their classification. In some cases, the air compressor safety valve cannot be opened. Today, Dehaha will explain in detail.
1、When the pressure value of the air compressor grows too fast, the exhaust speed of the safety valve cannot reach the growth rate of the pressure, we absolutely cannot open the safety valve in this case, because the first time to stop the operation of the equipment.
2、Different types of air compressors use different environments and have different requirements for sealing performance, in some cases need to be completely sealed, in this case, the safety valve can not be opened.
3、When the material in the container is solid or viscous liquid, the safety valve cannot be used, and once opened, the safety valve of the storage tank will not be sealed properly.
4、When the container material for toxic and hazardous substances, we can not easily open the safety valve, because the gas is directly discharged, easy to cause air pollution around.
In these cases we can not use the safety valve alone, must be used with the rupture disc or safety valve and rupture disc to ensure the safety of equipment and the environment.
