1. Summary

The hydraulic safety valve test bench of model YFS-A is used to perform checkout and leakage tests of popping pressure and blowby pressure of safety valves. The test bench is steady in performance, self-contained in outfit, and easy in operation. The main outfit of the test bench includes precise pressure gauge, bomb, subtle filter screen, gas pressure reducer and so on. In addition, all the needle valves and the pipeline of the test bench is made of stainless steel. As for the test of high pressure safety valves, the test bench can be equipped with an air booster pump of brand “Telide” which is imported from the USA.With this pump, safety valves with nominal pressure for 32.0Mpa can be tested. The test bench can be particularly designed and manufactured according to customers′ special requirements. By the way, the protective measures need to be settled by customers themselves.
