Abstract
The utility model relates to a water pressure seal test device can carry out water pressure seal test for self sealss valve gap and sealing washer. The hydraulic sealing device comprises a hydraulic sealing cover, a four-ring, a pressing plate, a bolt and a nut. The device covers the water inlet water injection through water pressure, rises pressure to hydraulic seal test pressure after waiting to fill with water, observes whether to have the leakage between sealing washer and the valve gap, verifies the sealing performance of sealing washer. The testing device solves the problem that the sealing performance of the valve sealing ring needs to be tested by a complete machine for multiple times.
Description
Technical Field
The utility model relates to a water pressure seal test device can carry out water pressure seal test for self sealss valve gap and sealing washer, verifies the sealing performance of sealing washer.
Background
When the existing self-sealing structure valve is used for a hydraulic sealing test, the valve is generally assembled, the whole machine is used for the sealing test after the assembly, once the leakage occurs from the sealing ring, the valve needs to be disassembled, the leakage reason of the self-sealing part is searched, the maintenance is carried out, and then the assembly is carried out again and the hydraulic sealing test is carried out until the hydraulic sealing test is qualified.
Disclosure of Invention
In order to solve the difficult problem that valve seal circle sealing performance needs complete machine multiple test, the utility model provides a water pressure seal test device carries out water pressure seal test to the valve gap and the sealing washer of self sealss structure valve, verifies the sealing performance of sealing washer.
The technical scheme of the utility model a hydraulic seal test device is provided, it includes hydraulic seal lid (1), by examination valve gap (2), by examination sealing washer (3), clamping ring (4), four close ring (5), clamp plate (6), bolt (7), nut (8). The method is characterized in that: and a seal is formed between the tested valve cover (2) and the tested sealing ring (3) under the action of the pretightening force of the bolt (7) and the nut (8) in the initial state. Water is injected into the test device through the water pressure sealing cover water injection port (9), after the test device is filled with water, the pressure is increased to the sealing test pressure, at the moment, the tested valve cover (2) and the tested sealing ring (3) form sealing under the action of medium force, and whether the leakage phenomenon exists is observed from the pressing plate (6).
The utility model has the advantages that: before the valve complete machine is assembled to carry out the hydraulic sealing test, the tested valve cover (2) and the tested sealing ring (3) are assembled with the device, then the device is used for carrying out the hydraulic sealing test, after the test is qualified, the tested sealing ring (3) and the tested valve cover (2) are disassembled, and after the device is assembled with other parts of the valve, the complete machine is used for carrying out the hydraulic sealing test, so that the primary qualification rate of the hydraulic sealing test of the valve can be improved.
