1, Overview
5, Using method
First, subjects were clamping valve
Model selection by the test station is not to be large diameter test valve, adjusting the test bench to the work of the left clamping position, the valve will be on the test bench trial left a sealed tray table to the clamping center, jog "Left radial feed>" button, will be pressed to claw into the trial of the valve flange is the correct position behind the plane, according to "the left axis tight" button "the light of the required clamping cylinder pressure comparison table" in the hydraulic pressed the system "by> PN value, according to" left-pressurization> "button, adjust" booster control valve ", the" left-pressurized form "tight cylinder pressure and the Cardiff pressure required for valve control in the table Path , pressure, PN value is the same, everything is correct, close the "gas master switch, gas pressure release switch". Open "water master switch, left to the water" not only for valve sealing test were tested.
Second, water pressure, water pumps use
Electrical contact to adjust water pressure gauge, water pump switch "low-pressure pump" to open, first test the valve within the water column has been filled, low water pressure gauge for the O 5MPa in the water is full, turn off the pump switches "low-pressure pump" off. And then "high-pressure pump to open" regulator for the pump pressure regulator valve, "for the water pumps, hydraulic system pressure reducing valve J-25B> pressure test the pressure of the liquid and is sealed pressure test valves and electrical contact pressure gauge the value of the same, high-pressure water pump is automatically shut down, turn off "the total water-switch". Packing a few minutes later, no decline in water pressure tables, test seal finished, open "pressure relief switch", will be test the pressure within the pressure relief valves, "pressure of the table" to zero, can relax the valve or both were tested continued strength test.
Third, subjects were strength test fixture valve
After the valve sealing test to continue to strength testing, left to clamp the same, adjust the right-clamping device to the test bench, according to "mobile rack into the>" button, the mobile rack tray sealing one end of the main disk, and enter the subjects were touching the other side of the valve flange, refer to the left to process, the right-hand side pressed, and control "comparison table clamping cylinder pressure required to" in the hydraulic clamping system pressure "Booster> PS the same value, open "right to water" to open the valve seals were tested, the reference to "=, water pressure, water pump to use to carry out the valve strength test.
Forth, was test valve gas seal testing methods, "user-owned gas source connected" to make gas seal test, can only be left to seal the work test will be on the left of the main disk plane rotated 90 degrees upward, then "spin up>" button, Then "a" step in the degree, they will be clamping style valve is completed, close the master switch c water, pressure relief switch, right to the water,. Open c gas master switch, gas switch, to be immediately try the other side of valve, the injection of water, observe the subjects were within the valve sealing performance and bubbles. Testing finished off "gas master switch" open "pressure relief switch", barometer pressure to zero, and then test the valve was removed.
