Introduction of Dory Safety Valve Calibration Test Bench

       The Dory YFJ-A Safety test bench integrates hydraulic, mechanical, electrical and medium storage cycles water tank. It has the advantages of reasonable structure, perfect function, stable performance and high degree of automation. It is widely used in high, medium and low pressure sealing and take-off performance of flanged safety valves. It is the most ideal valve testing equipment for valve manufacturing, petroleum and petrochemical, natural gas, water supply and drainage engineering, power plants, valve maintenance stations and other industries.

        YFJ-A200 hydraulic safety valve test bench consists of hydraulic system, electrical control system, oil pressure and air pressure instrument system, water booster system (maximum pressure: 40MPa), air booster system (maximum pressure: 25MPa), mechanical system and Hydraulic medium storage cycle composition. The test process and results conform to the regulations and requirements of relevant valve testing standards.The test bench adopts the method of pressing the back of the flange of the safety valve under test with the clamping jaw, which has no external force on the valve body, and performs the jump test and the sealing test on the safety valve under test. The hydraulic system is the main power source of this test bench and is used for the execution of hydraulic cylinder drive functions.
