The hydraulic cylinder top pressure valve test bench is a universal, efficient, and powerful valve testing equipment. The core design concept is to use the axial thrust generated by the hydraulic cylinder to directly drive the end face sealing pressure plate or blind plate, and to compress and seal the tested valve between its end flanges, thereby conducting the valve’s shell strength test and sealing performance test.

The hydraulic pressure holding valve test bench has two workbenches on the left and right, each equipped with a movable pressure claw clamping mechanism that can synchronously adjust the position of the pressure claw according to the flange size of the valve. The left workbench can be horizontally moved to accommodate the structural length of valves of different specifications and pressure levels, while the right workbench can be flipped 90 ° to facilitate leakage detection during single-sided sealing testing of valves.

The hydraulic pressure holding valve test bench is a specialized equipment for performance inspection and testing of flange valves, developed in accordance with the national standard GB/T 13927-2008 “Industrial Valve Pressure Test”, the mechanical industry standard JB/T 9092-99 “Valve Inspection and Testing”, and the American Petroleum Institute standard API 598 (9th edition 2009.9), relying on the Fluid Machinery Research Institute of Shanghai University of Technology.

The hydraulic pressure holding valve test bench is an efficient and accurate specialized equipment for valve performance testing. It adopts an advanced hydraulic control system, which drives the clamping mechanism through a hydraulic cylinder to achieve fast and strong clamping and fixing of the valve, and then conducts sealing performance tests (shell test and sealing test) and strength tests on the valve. This equipment is widely used in quality control, product acceptance, and maintenance testing in industries such as valve manufacturing, petrochemicals, electricity, water supply, and gas. It is a key equipment to ensure the safe and reliable operation of…
