Spring safety valve opening, closing action is to rely on media pressure change and spring preload its inlet end to the spool automatically open and close. When the medium pressure (internal pressure) rises to the lifting force than the spring preload force, the spool against the spring preload automatically turns on temperature and pressure valves, relief valves excess media so that the internal pressure decreased, and the spring force effect, when the internal pressure dropped to a safe value, the valve closes automatically stop the bleed. Spring safety valve is limited to a safe pressure range cooker in stainless steel exhaust valves, to ensure the safe use of equipment. Spring structure, performance is the key to the valve. Spring safety valve is a device for cleaning the exhaust pipe is blocked due to misuse or established. Shandong Everbright Valve Co., Ltd. specializing in the production valve manufacturers, welcomed the new and old customers to order our products! Safety valve safety valve check test methods Current methods commonly used power systems are off-line and on-line measurement of the two measurements. Off-line measurement devices need to be removed in the safety valve to stop the valve test bench models, is time consuming and laborious, and that such measure does not resolve the safety valve opening pressure temperature effects, but some can not remove the safety valve ( such as welding valves, etc.) is powerless. Online measurement is divided into two real jump measuring and measuring instruments. Real safety valve jump measure would cause unnecessary harm, and noise pollution and safety issues measurement has become increasingly attracted attention, July 9, 1999 in Jinzhou, Liaoning Province plant safety valve school five dead and three injured in the tragedy should not forget experience.
