Spring micro-open safety valve with wrench
Introduction to spring micro-open safety valve with wrench
When the medium pressure reaches more than % of the opening pressure, the spring-type safety valve with wrench can be opened manually with a wrench.
The safety valve with wrench and spring micro-opening is suitable for equipment or pipelines with steam, air and other media with an operating temperature of ℃. As an overpressure protection device, when the pressure in the equipment or pipeline exceeds the allowable value, the valve automatically opens and then discharges the entire amount. When the pressure drops to the specified value, the valve automatically closes to ensure the safe operation of the equipment and pipelines.

Three-band wrench spring slightly opened Detailed explanation of type safety valve
Spring safety valve with wrench consists of valve disc and valve seat forming the sealing surface. The valve disc is connected to the valve stem. The total displacement of the valve stem must meet the requirements of the valve from closed to fully open. The set pressure of the safety valve is mainly adjusted by adjusting the bolt to change the spring pressure. The upper part of the valve is equipped with a lever mechanism for manually lifting the valve stem during the action test. The valve body is equipped with two upper and lower adjustment rings. Adjusting the lower adjustment ring can make the valve obtain a complete take-off action, and the upper adjustment ring is used to adjust the return pressure. If the reseating pressure is too low, the valve will remain open for a long time. If the reseating pressure is too high, the valve will continue to jump and close, causing flutter, causing valve damage, and also reducing the valve's discharge. The optimal position of the upper adjustment ring should allow the valve to reach full stroke.
