Safety valve of air compressor is composed of what constitutes

        Safety valve is to ensure that pressure vessels and piping, safety critical application security, in order to guarantee the normal workand life extension of safety valve safety valve, safety valve in use,should be regularly check whether leakage in the operation,blocking and spring corrosion and not normal phenomenon, andobserve the adjusting sleeve and the adjusting ring fastening screwlocking nut is loose, if discover a problem in time to take the appropriate maintenance measures. Also should be regularly will conduct a comprehensive cleaning, inspection and re grinding,setting before reuse safety valve is removed. 

      The safety valve is installed on the outdoor should take appropriate protective measures, to prevent rain, fog, dust, rust and other dirt intrusion ofsafety valve and the discharge pipe, when the environment is belowzero degree Celsius, also should take the measures necessary to ensure the reliability of safety valve.

      Suitable for: urban construction, chemical industry, metallurgy,petroleum, pharmaceutical, food, beverage, environmental protection.

Engineering Chain

      Composition

     Ball valve and diaphragm type safety valve, working principle is identical with the piston. The three control valves are available spring force, spring preload adjustment, you can change the size ofthe security value, it is called direct acting safety valve.

      Pilot type safety valve, providing a control pressure acting on the diaphragm to a small direct acting valve, diaphragm valve is the hard core, the pressure on the seat. When the air pressure is greater than A the security pressure, the valve open, compressed air output from the left side hole into the atmosphere.

       Diaphragm type safety valve and pilot safety valve pressure characteristics of good, sensitive action; but the biggest opening force is relatively small, the poor flow characteristics. In practical application, should be based on the actual need of type safety valve, and based on the maximum discharge capacity to choose their path.
