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 0阀试验台试验标准和试验方法提供依据 Using the WK-12 0 test bench and the 12 0 valve test system simulation program established according to the gas flow theory, the range of the inflation curve of the qualified valve under the initial inflation test conditions was analyzed. The fastest and slowest vice cylinders of the qualified valve were found And to speed up the easing of the aeration curve of the air cylinder, three test methods and test standards for shortening the initial inflation test are put forward, which provide the basis for shortening the test time and revising the test standards and test methods for 120 valve test stands
