The D-type series hydraulic valve test bench integrates electromechanical, hydraulic, and pressure testing liquid medium storage and recycling. It has the characteristics of complete functions, stable performance, and high degree of automation. The entire pressure test process is controlled by hydraulic transmission electrical appliances, exerting external force on the tested valve without any additional influence on the test results. It is widely used in flange type, wafer type structure high, medium and low pressure butterfly valves with nominal diameter DD, and wafer type check Various performance tests such as sealing and strength of valves and knife valves. Maximum sealing test pressure and strength. The D-type hydraulic butterfly valve test bench uses the flange end face of the tested valve as a positioning seal, and is driven back and forth by a hydraulic cylinder to compress the workpiece under test. In order to minimize the influence of external force, the output pressure of the compression cylinder is randomly controlled at (.-.) pressure level and the pressure increase adjustment is selected so that the tested valve can be tested under different diameters and different pressures. The radial forward and backward movement of multiple axial compression cylinders adopts the reciprocating drive of a straight cylinder to realize the connecting rod principle to drive the synchronous movement of multiple axial clamping cylinders.
