Product details |

JLT type stand hydraulic valve test bench is stand valve testing equipments designed according to the standard criterion requirements of national GB/ T13927-92 and ZBJ6006-90. The technique of this testing bench has the advantages of advanced, perfect function, skillful structure, convenient utility which is applied for testing the airproof performance for various high-middle-low pressure valve and fiber valves.

Work principle and structure

JLT type testing bench do performance test to various valves with the method combined active claw and hydraulic ressureo cylinder, no outer force to tested valve that affect the testing result, accord with the testing requirements of national standard.

The structure of this machine is composed of hydraulic system and electric control system, working bench impact setting and hydraulic supplying quipment and medium circulation system. The workbench impact setting drives with hydraulic cylinder to realize every claw under equal force, the clamping is credible. The radial movement function of clamping equipment is composed of cylinder drive connection-rod, to realize synchro movement for every claw. The top of work bench clamping equipment sets with beam and main pole. The upper hydraulic cylinder top pressure on the beam will realize the ntension test for various different valves.

This machine can test the airproof performance and intension performance for water, air and oil.

This machine takes valve flange face as airproof orientation; the radial moving claw in the working bench will control the size off lange of tested valve, then adopts the method of clamping the back of flange with axial claw impacting valve to realize airproof test to various valves with different DIN.
