- product introduction:During the operation of the water supply system, the water flow direction of the main pipeline from left to right controls the water to enter the pilot valve control room. When the water pressure is less than the set pressure relief value, the thrust force of the pilot valve spring is greater than the water pressure, the pilot disc is closed. Another control water through the throttle needle valve into the main valve chamber after a static pressure, the chamber pressure and the pressure generated in the runner is equal. Because the main valve disc on the plane is larger than the lower plane, so the pressure of the upper chamber on the disc is greater than the main flow of water on the disc thrust, so that the main valve in the closed state. If the water pressure in the main pipe rises and exceeds the set pressure relief value, the water pressure in the control pipe into the control room increases and the water pressure is greater than the spring thrust. As a result of the throttle control, filling insufficient water, resulting in a reduction in pressure on the main valve chamber, the main valve with the disc below the pulp ice. Flow thrust large hand chamber pressure, disc rise, the main valve to open the rapid pressure relief. As the above process is completed in an instant, so the indoor fire water supply system in the occurrence of overpressure, will not cause harm.
