Product Description
Product Description Air compressor safety valve is a kind of automatic pressure relief protection device opened by the inlet static pressure, it is to prevent equipment and container abnormal conditions under the pressure too high explosion and set up safety device.
When the pressure in the equipment exceeds the allowable value, the safety valve opens automatically, then the full volume (full opening) discharge, when the pressure is reduced to the specified value, the safety valve automatically closes to protect the safety of the equipment.General air compressor valve is installed above the oil and gas separation cylinder, air compressor in the normal pressure is normal state of the relief valve is closed, problems of the machine under the condition of rising pressure relief valve will automatically open, release the pressure of oil and gas inside the bowl, to prevent the occurrence of an accident, machine pressure high general relief valve opening pressure is higher than rated pressure of the air compressor 0.1 MP.
