Survey source is forced into test pressure, and the port of export of observation spiral shell seat is with the presence or absence of leakage；
Ii, when the upper sealing of stop valve is detected, plug is sealed into the spiral shell seat port of export, and open stop valve, observation cuts
Only valve（Whether there is leakage at sealing on 9；
Iii, when the pressure-resistant performance of stop valve is detected, the plug on the spiral shell seat port of export is unclamped, and close stop valve, pass through
Detection source is forced into test pressure, and the port of export of observation spiral shell seat is with the presence or absence of leakage.
Have the first side plate of regulation, guide rod and the second side plate horizontal for various sizes of stop valve, on the fixed base plate
To the adjustment structure of position, when next stop valve to be detected is different from the stop valve size that this is detected, the first side is adjusted
Plate, guide rod and the second side plate lateral attitude.
Compared with prior art, the beneficial effects of the invention are as follows：Detection means of the invention is simply portable, can be quickly real
The clamping of existing cryogenic globe valve, sealing, while repeatedly different detections can be carried out in same detection means, including air-tightness,
Upper sealing, pressure-resistant etc., and can detect that different length is advised by appropriately designed slideway length and the dismountable side plate of regulation
The cryogenic globe valve of lattice.
After using the detection assembling device, the detection of cryogenic globe valve is simple and convenient, greatly improves detection efficiency,
And the reliability of detection is improved, can be used for the multinomial detection of cryogenic globe valve.
Below in conjunction with drawings and Examples, the present invention is further elaborated.

Specific embodiment
A kind of detection means of cryogenic globe valve, as shown in Fig. 2 including：
The first side plate 2 for connecting sealed steel pipe end, screw rod connecting seat 1（Containing O-shaped rubber ring, rubber mat plate）By spiral shell
Line is connected on the first side plate 2, and the one end of screw rod connecting seat 1 is connected by screw thread with test side, is sealed using O-shaped rubber ring, separately
One end is connected with the steel pipe of stop valve 9, is sealed using rubber mat plate；
For fix two blocks of side plates 2,8 and with slideway fixed base plate 3, may be mounted on fixed test support,
Can be used for portable detection；
For the spiral shell seat 4 of detection and the end of thread of fixing seal cryogenic globe valve 9（Containing O-shaped rubber ring, screw, pressing plate etc.）,
The O-shaped rubber ring that is connected by with the valve end of thread is sealed；
For detecting the plug sealed in cryogenic globe valve 9（Containing O-shaped rubber ring）, it is connected through a screw thread and is installed on spiral shell seat 4
On, sealed using O-shaped rubber ring；
Guide rod for connecting spiral shell seat 4 and fixed base plate 3, drives spiral shell seat 4 to be moved in the slideway of fixed base plate 3 by guide rod
It is dynamic；
For the adjusting screw rod 7 for clamping and move（Containing regulation handle）, it is connected through a screw thread installed in dismountable second
On side plate 8, one end connection spiral shell seat 4, other end attended operation bar；
For the dismountable mobile side plate 2,8 of adjustable range, it is installed on fixed base plate 3；Other be used for connect and
Fixed annex, such as bolt, nut.
As shown in figure 1, end is taken over using rubber slab sealed stop valve 9 by compressing mode, by screw thread plus O-ring seal
Connecting detection source come solve cryogenic globe valve 9 adapter end with the connection sealing problem between detection source.
As shown in Fig. 2 solving the problems, such as that stop valve 9 takes over different in size by slideway, the preceding pushing by slideway is tight
The salable position being connected with stop valve 9, moves afterwards, can change rapidly to next stop valve to be checked 9；Slideway can suitably be lengthened
The distance stop valve 9 longer to detect adapter；
Fixed base plate 3 of the invention is furnished with mounting hole, is securable in test operation platform；It is easy to carry after dismounting, is only needed
Connecting detection source is to be capable of achieving the detection to stop valve 9.
After each part such as Fig. 2 are assembled, specific detecting step is：
1. detection source is made to be connected firm with screw rod connecting seat 1；
2. then allow adjusting screw rod 7 to unclamp to cryogenic globe valve 9 can be put into, stop valve 9 is inserted in screw rod connecting seat 1, lead to
Cross handle and adjusting screw rod is progressively moved to the end of thread of stop valve 9 and spiral shell seat 4 and suit and compress, cryogenic globe valve 9 completes this
Handwheel direction should be upward when individual step；
3. when valve air-tightness is detected, 5 plugs are unclamped, closes cryogenic globe valve 9, experiment is forced into by connection source
Whether pressure, the observation oral area of plug 5 is revealed；
4. when the upper sealing of check valve, plug 5 is sealed, open cryogenic globe valve 9, in observation at sealing whether
There is leakage；
5. pressure test sees that with reference to step 3. other experiments can be carried out according to test index, after the completion of detection, by regulation
Screw rod 7 unclamps the next valve of detection；
6. when the adapter of cryogenic globe valve 9 exceedes slideway scope, the second side plate 8 can be moved to the mounting hole at rear, also may be used
Suitably slideway is lengthened when designing and producing.
It is only above presently preferred embodiments of the present invention, according to above-mentioned design, the designer of this area can also do to this
Go out various changes and conversion, for example：Two ends can be by similar close with the stop valve that two ends are screw thread for the stop valve of welded still pipe
Envelope mode detects that present case contains fastener for connection and threaded connection two types；Meanwhile, remaining imports and exports similar valve
Also quick assembling can be realized as with reference to suitably modified, once assemble the high efficient detection method of repeated detection.Present case does not have
There is specification to limit, the frock that can be matched with valve according to the specification sets itself of valve, similar this change and conversion etc.
Belong to protection scope of the present invention etc. that all should work as.
