- Abstract:
- In order to find the reason which affects the pressure-establishment stability of the relief valve and obtain the stable pressure-establishment process at outlet of the relief valve, the starting characteristics of a pneumatic system used in some propulsion system were researched by means of system simulation method and relevant tests. The result shows that the pressure stability behind the relief valve depends on the diameter of the pipe behind this valve and damping area inside this valve.
