          气动阀的性能检测　

　1阀门某一规格批量制造时，鸭嘴阀 应委托权威性机构进行以下性能的检测：

　　①阀门在工压状况下的启闭力矩；

 　　②在工压状况下，电站阀门能保证阀门闸门 关闭严密的连续启闭次数；

 　　③阀门在管道输水状况下油田阀
的流阻系数的检测。

　　2阀门在出厂前应进行以下的检测：

　　①阀门在开启状况下，冶金阀门阀体应承受阀门工压值二倍的内压检测；

 　　②阀门的关闭状况下，两侧分别承受1.1倍阀门工压值，无渗漏；但金属密封的蝶阀，渗漏值亦不大于相关要求。

             Pneumatic valve performance testing A valve of a standard high-volume manufacturing, the authoritative body should be entrusted to the following performance test: ① pressure valve in the working conditionsPlug Valves of the opening and closing torque; ② pressure in the working conditions,Bellows Seal Valves to ensure the continuous opening andButterfly Valves closing the valve tightly closed times; ③ valve in the pipe flow resistance coefficient under conditions of detection. 2 valves in the factory before the following test: ① valve in the open position, the valveSafety Valves body should bear the value of two times the working pressure within the pressure test; ② valve closed position, the sides were Check Valves working pressure valve to withstand 1.1 times the value, no leakage; but the metal sealing butterfly valve, leakage is no greater than the value of the relevant requirements.
