1 .Introduction
 
The safety valve test bench is a new type of pressure test device developed by our company for reference to GB/T 12242-2005 (pressure
 
 
release   device and performance test specification), which is used to adjust and test the setting pressure of the safety valve.

 

2, Function

 
The safety valve test bench can do the whole pressure test, the discharge pressure test, the back seat pressure test and the pressure safety
 
performance of various relief valves.

 

 3. System composition
 

It consists mainly of high pressure power system, clamping device system,  and so on 

1). power system(High-pressure power source).

 
Air driven gas booster pump- GBT60 air driven gas booster pump  
 
Driven air pressure: 3-8bar;
 
Output gas/air pressure 0-400bar;
 
Test medium: air, nitrogen

 2). Clamping system:


The power of the clamping device is provided by a manual hydraulic(oil) pump to provide clamping pressure
 
,Valve diameter range:DN15-DN400
