Valve test benches can be divided into the following types: Cut-off valves, control valves, safety valves, although the standards tested by the valve test bench are different, for each type of valve, the test method is roughly the same. The most important are the following: Detecting the strength of the valve body; detecting the sealing degree of the valve body, the stem and the valve shaft joint; detecting the sealing degree of the valve seat or the base (if possible); determining the take-off pressure of the safety valve.
Maximizing the benefits of the valve test rig and maximizing the stability and stability of the maximum benefit are the business objectives of every healthy company. Providing high-quality products at competitive prices is an effective way to cost-effectively use the resources that companies have. The economic viability of valve testing means that it is not only the case that various types of valves are tested using various standards at the lowest cost and cost. Ideally, valves of the same valve type but different manufacturers can be implemented. test. Only 100% inspection ensures the reliable quality of each valve.
The main functional principle of the valve test bench: the valve flange end face positioning, the hydraulic claws hold the valve flange back pressure sealing method, 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.
