One, the clamping valve test was
According to the test model selection path not tested valve, adjusting test bench left to work clamping position, the subject's valve on the test bench to the left clamping table sealing disc center, move the left radial inlet < > button, pressing claw into the tested valve flange behind the correct position, press < left axial locking button < > reference clamping cylinder pressure required to control table > hydraulic pressing system < >PN value, press < left to boost button, adjust the pressure regulating valve >, < Table > will be left plenum pressure and husband tension cylinder pressure required control table the valve size, pressure, PN value is same, all right, off < gas switch, the gas meter switch pressure switch >。 Open < water switch, left water inlet > can be tested valve sealing test。
Two, water pressure, water pump using the method of adjustment of water electric contact pressure gauge, low pressure pump switch < > open, the valve test was full of internal water, low water pressure gauge of O 5MPa is already full, turn off the water pump low pressure pump switch < >。 According to the high pressure water pump open > regulating water supply pump pressure regulating valve, a water pump, the hydraulic system pressure relief J 25B> liquid pressure test pressure is reached and the tested valve sealing pressure and electric contact pressure gauge value is same, the high-pressure water pump will automatically shut down, closed < > the total water switch。 Holding pressure after a few minutes, hydraulic table without falling, the sealed test finished, opened pressure relief switch >, will be tried in the pressure relief valve, hydraulic table <> nil, can relax the tested valve or while continuing strength test。
Three, subjects valve strength test clamping valve sealing test is finished, continued strength test, left to the clamping unchanged, adjust right to test clamping device, press < frame > button to mobile, the mobile rack end main plate sealing disc, into the tested valve flange at the other end is touched, with reference to the right end of the left program, pressing, and control the clamping cylinder pressure required to control table > in < boost pressure hydraulic clamping system have the same >PS value, opened right water inlet > open valve test was sealed, with reference to them, water pressure, water pump using method, carries on the valve strength test.
Four, subjects valve air tightness testing method, the source user owned connection > gas seal test, only in the left sealing test will be left to work the master disc is rotated 90 degrees upward rotation plane, then < > button, then <1> steps degree, will be type valve is setup, close C the total water switch, pressure switch, right water inlet,。 Open C gas switch, the gas meter switch,, to the tested valve immediately in the other end, into the water, to observe the subjects within the valve sealing performance and air bubbles。 The test finished off the gas main switch > Open < > pressure switch, pressure gauge pressure is zero, then the valve test was unloaded。
