Main functional principle: The valve flange end face is positioned, the hydraulic claw holds the valve flange back pressure sealing method, and the axial compression and relaxation of the jaw mechanism on the left and right two-way table and the radial size advance and retreat work synchronously. The right-hand workbench is equipped with a 90-degree flip function, and the left-hand workbench is set to a balanced-type mobile stand to move horizontally. Each function transmission is controlled by a hydraulic drive electric button, and the pressure and pressure relief are manually controlled by a needle valve. According to the pressure level of the tested valve, the pressure can be adjusted up to the above (in the table) pressure.
Equipped with electric contact pressure gauge (the pressure can be automatically stopped when the valve is tested). During the test of water or gas pressure, if there is a high pressure in the valve cavity under test, any button will not work, and the pressure will be released until no pressure is available. (Be sure to be safe at work).
Equipped with high pressure water pump and electric low pressure water pump. The medium water, gas and oil can be stored and recycled, leaving the intake pipe joint (the demanding source is 0.8-1.0MPa).
Configure two-way pressure and pressure relief and set pressure and pressure relief device.
Shock-resistant pressure gauge, accuracy 1.6, standard MPa/Psi, test working pressure gauge to implement [three-level system], both: high, medium and low pressure gauge, using: 25.0MPa, 10.0MPa, 6.0MPa.
