Degree, and through hole 172 area less than blockage body 151 cross section.For the ease of rotating rotary press head 17, have on rotary press head 17
There is the boss 174 of the upper surface for protruding from fixed lower platen 16.
In a preferred embodiment, the replacing device for gate valve of not giving up also includes stud 18, the one of stud 18
End is connected connecting plate 11, and the other end is connected lower platen 16.The structure be easy to not give up this replacing device for gate valve with
Tubing head 21 links together.In the present embodiment, the replacing device for gate valve of not giving up includes two studs 18, adjacent respectively
Nearly two support bars 12.
It should be noted that the alleged gate valve 19 of changing of the present invention can change whole gate valve 19, or replacing lock
Part on valve 19, such as upper flange 20.Below just as a example by changing the upper flange 20 on gate valve 19, introduce and of the invention do not lose
The application of rim brake valve replacing apparatus.
Fig. 1 to Fig. 3 is refer to, when needing to change the upper flange 20 on gate valve 19, fixed connecting plate 11 is passed through into double end
Bolt 18 is connected in the draw-in groove on tubing head 21, and two support bars 12 are fixed on fixed connecting plate 11.Then, by fixation
Top board 13, feed beam 14, Qu An mechanisms 22, blanking plug are assembled by above-mentioned annexation, by the two ends of fixed top board 13
It is enclosed within support bar 12.Then the gate valve 19 of the top of tubing head 21 is opened, fixed top board 13 is promoted, feed beam 14, peace machine is taken
Structure 22 and blanking plug are moved down, and make feed beam 14 and blanking plug through gate valve 19, during blanking plug delivered into tubing head 21, seal oil pipe
Blanking plug in first 21 is setting, so as to block shaft bottom air-flow overflow.
Then, fixed top board 13 is fixed on support bar 12 with fastener, now, feed beam 14 connects with blanking plug
Connect, because fixed top board 13 is fixed, therefore, blanking plug is pressed on pre-position by feed beam 14.Then, by Qu An mechanisms
22 inner cylinder is connected with gate valve 19, releases the annexation of upper flange 20 and tubing head 21, the inner cylinder of Shi Quan mechanisms 22 relative to
Outer barrel is retracted, so as to drive shifting one end distance on gate valve 19, vacates the space for installing blanking plug fixing device.Then, will block
Device fixing device is enclosed within connecting rod 152, even connecting rod 152 is through the first opening 161 and the second opening 162, into through hole
In 172.Then fixed lower platen 16 is pushed, the groove 173 of the lower end of rotary press head 17 is enclosed within the upper end of blockage body 151, so that,
Rotary press head 17 coordinates with blockage body 151, compresses blockage body 151 in the precalculated position.Meanwhile, the two ends of fixed lower platen 16
It is connected with two studs 18, the fixation lower platen 16 is pressed on the top of tubing head 21.Rotary press head 17 is rotated, makes to block up
Cock body 151 closely seals blanking plug seat.
Then, because blanking plug fixing device now plays restriction effect to blanking plug, blanking plug will not be shifted, now,
The annexation of feed beam 14 and connecting rod 152 can be released, while fixed top board 13 is unlocked from support bar 12, will be solid
The gate valve 19 determined top board 13, feed beam 14, Qu An mechanisms 22 and be connected in Qu An mechanisms 22 hangs, will be old on gate valve 19
Upper flange 20 be replaced by new upper flange 20.Top board 13, feed beam 14, Qu An mechanisms 22 will be fixed again and is connected to take peace
Gate valve 19 in mechanism 22 is hung back, and fixed top board 13 is enclosed within support bar 12, moves down fixed top board 13, and reconnect is sent
Enter bar 14 and connecting rod 152, feed beam 14 is compressed blanking plug, be locked top board 13.Then, stud 18 is unclamped,
Remove blanking plug fixing device.The inner cylinder of Shi Quan mechanisms 22 stretches out relative to outer barrel, so as to gate valve 19 be resetted, will be new upper
Flange 20 is connected with tubing head 21.Then, fixed top board 13 is unlocked, top board 13, feed beam 14 will be fixed and be connected to
Blanking plug in feed beam 14 hangs together, bleeds off residual air beyond the valve plate of gate valve 19, support of dismantling, so as to complete to replace with method
Blue 20 overall process.
As can be seen here, provided in the present embodiment do not give up replacing device for gate valve can not give up it is with pressure in the case of
Change and recover the oil（Gas）The four-way gate valve of tree（Upper flange）And gasket ring etc., it is ensured that change valve process safety reliability；Avoid
Yield caused by kill-job is reduced, so as to be effectively protected petroleum resources；Avoid the environmental pollution caused by kill-job.And
And, the replacing device for gate valve of not giving up provided in the present embodiment can make workman more easily change gate valve, and not
Kill-job is needed, the efficiency of replacing gate valve is greatly improved.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
