Jinan Saisite off-line safety valve calibration bench, simple safety valve test bench
The off-line safety valve calibration table is divided into digital display meter control and computer control

Safety valve test bench (digital display): can be achieved  
1) Collect takeoff pressure and reseating pressure  
2) Pressure holding time, pressure and differential pressure setting  
3) Selection of card holder  
4) Selection of clamping force   It completely realizes semi-automatic detection, which is different from the manual control type produced by other manufacturers

Safety valve test bench (computer-controlled safety valve calibration bench):
The data acquisition software of American NI company is adopted, which has powerful functions and stable performance
The whole experiment process can be completed automatically on the computer, and the pressure curve can be displayed
Various test parameters can be set freely, such as test pressure, pressure holding time, allowable pressure drop, etc

Main functions of safety valve calibration table
The safety valve calibration bench uses high-pressure air as the medium to test the sealing performance, take-off pressure, reseating pressure, etc
of the safety valve

Typical application of safety valve calibration bench
DN32 ~ 400mm flange safety valve,   ″~ ″ Performance test of threaded safety valve, full lift / micro lift safety valve, conventional thick and thin flange safety valve, domestic / imported safety valve, spring direct load safety valve, safety valve with power auxiliary function and safety valve with supplementary load
