surge relief valve

水击泄放阀feature
1. Hydraulic automatic control: At any time during use, it can quickly and normally sense system pressure changes caused by sudden power outages, pump shutdowns, or valve closures, unconditionally relieve overpressure, and have the function of sensing high pressure to open and release water, preventing water hammer from instantly rising. It can also slowly close the main valve to prevent self closing water hammer, without the need for manual operation to control valve closure.
2. The water hammer relief valve operates smoothly and without vibration: The main valve adopts a differential diaphragm structure design, which enables the main valve to have approximately linear adjustment characteristics throughout the full flow range. Especially when a slight water hammer occurs and the required discharge flow is very small to meet the protection requirements, the valve disc only needs to be opened slightly to avoid "frequency jumping" of the diaphragm, ensuring smooth operation of the main valve without valve closing water hammer; At the same time, when the main valve is fully opened, the flow area should not be less than the normal required valve port area for that size of valve, and the valve port overflow area should not be reduced.
3. Strong closing force: Even under low working pressure, the structural design of the main valve may provide reliable working power, ensuring automatic closing when pressure returns to normal. The main valve structure adopts a differential diaphragm type to ensure reliable closing force under any working pressure.
4. Slow closing: The water hammer relief valve has a slow closing structure; Prevent self closing valve water hammer.
5. Anti cavitation performance: Due to the fact that water hammer relief valves usually discharge directly into the atmosphere, high-speed water flow and cavitation are prone to occur whenever they are opened. The water hammer relief valve can protect the valve seat from cavitation damage and avoid the impact of high-speed discharge fluid flow.
