The condensing pressure regulating pneumatic valve is introduced

condensing pressure regulating pneumatic valve is actually an adjustive pneumatic valve, often used in the water cooled condenser cooling device, installed at the condenser inlet, pneumatic valve with a capillary tube and the top of the refrigeration compressor exhaust pneumatic valve on the bypass hole is connected. When the condenser water temperature too high or into the water shortage, the refrigeration compressor exhaust pressure rise, pneumatic valve bellows is compressed inside, make through regulating mechanism of rubber pneumatic valve open, into the water, thus reduce refrigerant condensing pressure in the condenser. When refrigeration unit for some reason cause condensation pressure below the set value, adjusting the upper part of the pneumatic valve is less pressure, pneumatic valve bellows expansion, up regulating mechanism drive the pneumatic valve, pneumatic valve will shut, entering the condenser water flow is reduced, condensing pressure, keeping condensing pressure and condensation temperature basically in the range of set, thus ensuring the compressor running under the best condensing pressure.
