safety relief valve

Structural characteristics:

This product consists of a main valve, a pressure relief pilot valve, a ball valve, and a connecting system. The main valve adopts a full channel, DC, streamlined design, and adopts two types of structures: diaphragm or piston. This valve uses a pressure relief pilot valve to set the pressure relief, and adjusting the spring of the pilot valve can set different pressure relief values. Control the valve opening and closing through the main valve control room to achieve pressure relief function. This product is independently controlled by the main valve, pressure relief pilot valve, and connecting system for water pressure, without the need for additional devices or energy sources. The structure is simple and reliable, with accurate pressure control and easy maintenance.

Job characteristics

By transmitting pressure through hydraulic conduits, the sliding disc (valve disc) of the main valve imitates the action of the pilot valve. As long as the upstream pressure is lower than the set value of the pilot valve, the pilot valve closes and the upstream pressure acts on the diaphragm, keeping the main valve closed. Once the upper pressure rises above the set pressure of the pilot valve, the pilot valve opens and releases a large amount of water to reduce the pressure to the set value before slowly and smoothly closing without generating secondary water hammer.

1. Close tightly and reliably. The main valve seal adopts a rubber sealing ring seal, and the closing power is automatically formed by the main valve control room to maintain appropriate closing force, with high sealing life and reliability.

2. Easy to operate, no need to equip the valve with an electrical control system or other additional devices.

3. Control pressure without being affected by factors such as flow rate to ensure accurate pressure relief.
