So as to squeeze lower seal 307.
The locating support 10 is fixed on lower positioning plate 302, locating support 10 it is cylindrical and with lower end cover
301 coaxial arrangements, 10 internal via shape of locating support are matched with the clamping of 11 body shape of valve, and 10 upper end-face edge of locating support opens up
It is useful for the valve rod positioning port 101 of 11 intermediate valve rod of positioning valve positioning.
The lower positioning plate being between 2 bottom of lower positioning plate 302 and water tank is arranged on two polished rods 5 to reply
Spring 9.Since lower positioning plate 302 can be pressed down in test process, lower positioning plate returning spring 9 can will test the lower fixed of completion
Position plate 302 is restored to original height, so as to cycle the test for carrying out next valve 11.
Before test, a certain amount of water is first poured into water tank 2,12 requirement of water level can be higher than valve in 11 test process of valve
11 intermediate valve rod height of door, as shown in Figure 7.During test, valve 11 is put in vertically in locating support 10,11 side wall of valve is with determining
Position 10 endoporus of stent clamping positioning, 11 lower end of valve are inserted into lower piece of open slot of lower end cover 301 in lower sealing mechanism 3
In 305, the intermediate valve stem spacing of valve 11 is in valve rod positioning port 101, towards fixed-direction, convenient for people during the test
Observation leakage bubble.Start cylinder 6, entirely upper sealing mechanism 4 moves down the driving of 6 piston rod of cylinder, in folding process, on valve 11
End end is introduced into upper piece open slot 407 of the upper end cover 401 in upper location-plate 402, when valve is held for two about 11
When portion contradicts respectively with the opening trench bottom of upper and lower two end covers, since the opening trench bottom of two end covers is designed with
Primary seal is realized in gasket, 11 end of valve.At this point, upper sealing mechanism 4 drives lower sealing mechanism 3 to move down together, upper sealing
End cap returning spring 406 in mechanism 4 starts to be compressed, and connecting plate 8 is slowly close with upper location-plate 402, on 8 downside of connecting plate
Upperpush rod 404 on end cap briquetting 403 into upper end cover 401 upperpush rod passage 410, in push in end cover 401
Upper press ring 412 squeeze upper sealing ring 409, upper sealing ring 409 is squeezed, and inwardly expands, embraces 11 upper end outer wall of valve, realizes
Secondary seal；Meanwhile the lower positioning plate returning spring 9 of lower 3 downside of sealing mechanism is also compressed, lower positioning plate 302 moves down,
Until the down-pressed pole 304 on 2 bottom bottom end cover briquetting 303 of water tank passes through the pushing of the lower end cover 301 on lower positioning plate 302
The lower pressure ring 310 of the push of bar passage 308 squeezes lower seal 307, and lower seal 307 inwardly expands, and embraces 11 lower end outer wall of valve,
Realize secondary seal.At this point, the stopping of valve 11 moves down, 11 both ends of valve are all sealed by end cover, and the water level 12 in water tank 2 is high
In 11 intermediate stem position of valve, you can tested.
Test mode can be divided into following two：1st, valve rod is opened, in the test stomata of upper and lower two end covers
Whether with air pressure capable of being increased simultaneously, observing at intermediate valve rod has bubble to leak out, and can judge whether leaked at valve rod among when valve is opened；
2nd, valve rod is closed, and the lower test stomata of lower end cover is connected with the water in water tank, up the upper test of end cover
With air pressure capable of being increased in stomata, whether have bubble leak out, can judge if observing at the lower test stomata of lower end cover and at intermediate valve rod
When valve is closed, whether leaked between upper and lower two cavitys and at intermediate valve rod.
