The screw top pressure valve test bench adopts screw top pressure and valve channel sealing type for various tests of the valve. The test bench is composed of left and right memorial archway, middle memorial archway, pull rods, jacking screw nut pairs and driving devices, V-shaped support system, waterway system, electrical system, etc.
The screw top pressure valve test bench is a classic, reliable, and economical valve testing equipment. It adopts the principle of mechanical spiral force amplification, which drives the screw through the motor to generate strong axial thrust force, pushes the sealing pressure plate to compress and seal the tested valve, thus conducting the strength test and sealing performance test of the valve shell.
