缩短120阀试验时间的标准与方法探讨

Discussion on the Standard and Method to Shorten the Testing Time of 120 Valves

利用根据气体流动理论建立的 WK— 12 0型试验台和 12 0阀试验系统仿真程序 ,分析了初充气试验条件下合格阀充气曲线的范围 ,找到了合格阀的最快与最慢副风缸和加速缓解风缸充气曲线 ,提出了缩短初充气试验的 3种试验方法和试验标准 ,为缩短试验时间、修订 12

With the use of the WK-120 type test stand and the simulation program for 120 valve testing system set up according to the gas flow theory, the range of the charging curve for qualified valves under the initial charging test conditions is analyzed, and the fastest and the slowest auxiliary reservoirs for the qualified valve as well as the charging curve for the accelerated release cylinder are found, the three test methods and test standards to shorten the initial charging test are given, so that the basis is provided for reducing the test time, revising the test standard and test method for the 120 valve test stand.
