JWZ type horizontal hydraulic valve testing machine, hydraulic system, electrical system, mechanical system, pressure system of the four systems, composed of a frame, the left and the right working disk, the clamping oil cylinder, traction oil cylinder, the turning oil cylinder, a moving oil cylinder and the test medium control pipeline and a control valve, low pressure water pump, high pressure water pump, oil pump and motor, test medium control pipeline and a control valve, hydraulic control system, electrical control system, the test pressure measurement.

The clamping valve type for holding type, both ends of the flange and the blind plate valve measured, respectively by clamping jaw working disk holding pressure clamping, right working disk in the turning cylinder under the action of 90 degree turn, in order to seal test to observe and check the seal leakage, work pressure claw plate in the radial direction of the valve flange according to the size of the traction under the action of the oil cylinder can be synchronized wide and narrow, in the axial direction according to the valve flange thickness, the clamping cylinder under the action of synchronous compression and relaxation, disk can be left to work according to the length of the valve structure length, can move around in the mobile cylinder under the action of high pressure water pump and medium circulation water tank system development, make the medium cycle use, pressure gauge control valves and electric button switch, designed for operation control on the test bench in front of, can make the transfer mechanism of CO The operation is convenient, safe and reliable, and meets the needs of user testing.
