摘要(Abstract):

介绍了一种利用外接气源 ,向安全阀瓣与爆破片形成的隔离腔内直接充压 ,对安全阀进行在线检测的方法。该方法具有压力直接作用、检测结果准确、操作简单、不排放有害介质、且不易损坏安全阀、适用于粘性大及含有固体颗粒等介质场合 ,有很好的推广应用价值。
A new technique is described for safety-valve on-line testing in which out-source gas is introduced into the cavity enclosed by the valve plug and rupture disk. With the pressure applied directly and convenient for operation, this technique is characterized with high accuracy, no harmful medium discharging, no damage to safety valve as well as good suitability for the medium with high viscosity and solid particle in it. It is well worth promoted for wide application.
