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 testing stage, that is time-consuming and laborious temperature and pressure valves, and that such measure does not resolve the influence of temperature on the safety valve opening pressure of high temperature and high pressure valves offer, but some can not be removed Under the safety valve (such as welding valves, etc.) it 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. Safety valve inlet and outlet piping (1) safety valve and the boiler or pressure vessel connection between the pipe and fittings through-hole, its cross-sectional area of ??not less than the cross-sectional area of ??the valve imported; if several valves share one inlet pipe, the import and flow area not less than the safety valve of the pipe cross-sectional area of ??the imports. (2) using a spring-loaded safety valve threaded connection of temperature and pressure valves vendors to be connected with the short threaded pipe, while the short pipe and simplified, philatelic box to use welded connections.

Off-line measurement devices need to be removed in the safety valve to stop testing stage, that is time-consuming and laborious temperature and pressure valves prices, and that such measure does not resolve the safety valve opening pressure temperature effects, but some can not remove security valve (such as welding valves, etc.) is powerless.
