JZ-7型空气制动保持阀设置必要性的分析

Analysis of Necessity of the Pressure Keeping Valve Installation in JZ-7 Air Pressure Breaker

笔者通过 JZ- 7型空气制动机设置与不设置保持阀的对比分析 ,从理论上论证了目前在JZ- 7型空气制动机上设置的保持阀 ,对改善列车缓解性能并未起到实质性的作用 ,从而得出了在 JZ-

The article first theoretically verifies the unnesessity of installing pressure keeping valve in the JZ 7 air pressure breaker by comparing the installation and non installation of such a device.Then in combination with the actual engineering situation,it proves that the pressure Keeping valve has no virtual effect on the train stopping process amortization.Thus it concludes that the pressure keeping valve is a superaboundant fatility for the JZ 7 Air pressure Breaker.
