Interior to add the water for being enough to normal read data, now, test equipment is ready.Start cylinder 20, drive location-plate 6 along light
Moved on bar 17, upper and lower end cap is moved also with location-plate 6, guide plate 22 above carried manually, guide plate 22 is also moved on polished rod 17,
Valve 14 is inserted vertically into the locating dowel 24 of float plate 19, the upper port of valve 14 is aligned immediately below upper and lower end cap, puts down automatically
Guide plate 22 so that the upper port of valve 14 is positioned through the pilot hole 23 on guide plate 22, further ensures the upper port of valve 14
Position, while, it is ensured that the middle valve element 15 of valve 14 is in opening, as shown in figure 1, retraction cylinder 20, location-plate 6 moves down, will
The bottom end cover 1 of test equipment is inserted from the upper port of upright valve 14, and then upper end cover 4 enters the upper port of valve 14, until fixed
Position plate 6 and the upper surface of valve 14 contradict, if as shown in fig. 6, the upper and lower end face of valve 14 is not parallel, upper and lower end cap insertion process
In, can be corrected by the floating spring 21 of the downside of float plate 19.Because the downside of location-plate 6 is provided with neonychium 12, location-plate 6 with
When valve 14 is contacted, the upper surface of valve 14 will not be damaged, and now, valve element 15 is between upper and lower end cap.Test equipment is pacified
Put after finishing, open the stop valve 11 of the upside of pressurization stomata 406, outside drives source of the gas 9 toward inflating pressure, air pressure in fixing pipe 5
By pressurization in upper pressure channel 403 up gas-flow closure circle 402, and will down be inflated by lower pressure channel 103 close
Pressurization in seal 102, upper and lower gas-flow closure circle receives compression swelling, props up the upper-lower seal ring on the outside of upper and lower gas-flow closure circle so that
Upper-lower seal ring and the inwall gluing, sealing of valve 14, just form a closed cavity between upper and lower end cap.Then, pressurized gas source
10 in closed cavity of the stomata 406 up between bottom end cover of pressurizeing by being filled with measuring air pressure, because the one end of U-tube manometer 7 is logical
Cross tracheae 8 to be connected with the test stomata 405 on upper end cover 4, i.e. closed cavity between the one end of U-tube manometer 7 and upper and lower end cap
Connection, when pressure increase in the closed cavity between upper and lower end cap, will cause the height of the left and right sides water column of U-tube manometer 7
Difference, just can read pressure difference, when the air pressure in closed cavity between upper and lower end cap is added to survey by the scale on U-tube manometer 7
During examination atmospheric pressure value, the stop valve 11 of the upside of pressurization stomata 406 is closed, stop pressurization, now, the closed cavity between upper and lower end cap
Just packing state is entered, operating personnel just can judge whether the whole chamber of valve 14 lets out by observing the pressure difference on U-tube manometer 7
Leakage.If the normal seal operation of upper and lower end cap, the pressure difference on U-tube manometer 7 is gradually reduced, illustrate that the whole chamber of valve 14 leaks；
If the normal seal operation of upper and lower end cap, the pressure difference on U-tube manometer 7 keeps constant, illustrate that the whole chamber of valve 14 does not leak.
During test 14 single-chamber of valve, without using bottom end cover 1, returning spring 302 is passed through in the contiguous block 3 on upper end cover 4
Squeezing sealing lid 303 blocks inner thread mouth 304 from inner side.Start cylinder 20, drive location-plate 6 to be moved along on polished rod 17, upper end
Lid 4 is moved also with location-plate 6, and guide plate 22 is above carried manually, and guide plate 22 is also moved on polished rod 17, in determining for float plate 19
Valve 14 is inserted vertically on the post 24 of position, the upper port of valve 14 is aligned immediately below upper and lower end cap automatically, puts down guide plate 22 so that valve
14 upper ports of door are positioned through the pilot hole 23 on guide plate 22, further ensure the upper port position of valve 14, while, it is ensured that valve
The middle valve element 15 of door 14 is in closed mode.Retraction cylinder 20, location-plate 6 is moved down, by the upper end cover 4 of test equipment from upright valve
14 upper port insertion, until location-plate 6 is contradicted with the upper surface of valve 14, as shown in fig. 7, test equipment was both disposed finishing, opens
The stop valve 11 of the upside of pressurization stomata 406 is opened, outside drives source of the gas 9 toward inflating pressure in fixing pipe 5, and air pressure will be by upper gas
The up interior pressurization of gas-flow closure circle 402 of pressure passageway 403, upper gas-flow closure circle 402 receives compression swelling, props up gas-flow closure circle 402
The upper sealing ring 404 in outside so that upper sealing ring 404 and the inwall gluing, sealing of valve 14, so, upper end cover 4 and valve element 15 it
Between just form a closed cavity.Then, pressurized gas source 10 by the stomata 406 that pressurizes toward between upper end cover 4 and valve element 15
Measuring air pressure is filled with closed cavity, the left and right sides water column of U-tube manometer 7 will form difference in height, by U-tube manometer 7
Scale read pressure difference.When the air pressure in closed cavity between upper end cover 4 and valve element 15 is added to measuring air pressure value, closes and add
Calm the anger the stop valve 11 of the upside of hole 406, stop pressurization, now, the closed cavity between upper end cover 4 and valve element 15 just enters guarantor
Pressure condition, operating personnel just can judge whether the single-chamber of valve 14 leaks by observing the pressure difference on U-tube manometer 7.If on
The normal seal operation of end cap 4, the pressure difference on U-tube manometer 7 is gradually reduced, and illustrates that the single-chamber of valve 14 is leaked；If upper end cover 4
Normal seal operation, the pressure difference on U-tube manometer 7 keeps constant, illustrates that the single-chamber of valve 14 is not leaked.
