DN20;PN25高压加热入水侧用弹簧式安全阀试验分析

Test Analysis for DN20; PN25 Spring Safety Valve by Hot Water and High Pressure at the Inlet of Medium Water

本文利用DN20;PN25高加用水侧用弹簧式安全阀在厂内试验的结果和在电厂验证的方法,证明了用低压法和等价弹簧法是行之有效的方法。同时也说明了,该阀门在设计上的准确、合理性,完全满足国际标准的要求。

Test DN20; PN25 spring safety valve by hot water and pressure at the inlet of medium water at our valve plant and power plant. It is effective way by the way of low- pressure- test and equivalence- spring- test. It is not only prove this testing valve is accuracy and rationality in design,but also prove this testing valve corresponds to international standard.
