Description
Technical field
This utility model relates to gas pipeline plugging device, a kind of for ground combustion gas purging stake blocks, prevents the combustion gas purging stake stopper that gas riser and distribution arm are connected.
Background technology
In the building using combustion gas, it is fitted with gas pipeline,
As shown in Figure 1, gas pipeline pipeline includes being positioned at underground distribution arm 11, also including the purging stake 12 resting on the ground and connecting with distribution arm 11, purging stake 12, by the curved standpipe 14 connecting logical building of tee T 13, the straight pipe at the top of tee T 13 is provided with pipe plug.
User is when normally using, and combustion gas can sequentially pass through purging stake, tee T, standpipe from distribution arm, and arrive user makes use.Speedily carry out rescue work in maintenance work at gas facility, when the indoor standpipe being connected with standpipe is replaced, need to separate tee T at the articulation of standpipe, use plugging device by the curved logical closure of tee T, i.e. allow purging stake isolate with standpipe.Outdoor purging stake and tee T are longer because of service life, mopping causes the gap between tee T and standpipe to be painted to fill up repeatedly, cause and cannot loosen at articulation, or force to cause other wire connection positions leak when dismantling, so cause blocking speed slowly, the problem of weak effect.
Improve to some extent, if notification number is the gas standpipe plugging device of CN102865385A, including guiding plug, it is fixedly connected with pull bar with described guiding plug, and be positioned at above described guiding plug, be linked in the lower end cap that described pull bar is sequentially connected with, lower lining, stifled cylinder, push pipe, stifled handle, the excircle of lower lining is provided with the first rubber ring, and the excircle of push pipe is additionally provided with port plugging module, and the top of pull bar is provided with the ratchet spanner of removable connection；Stifled handle is connected with pull rod screw, and lower end cap is slidably connected with stifled cylinder.This plugging device directly inserts in purging stake at pipe plug, blocks purging stake, eliminates the trouble splitting tee T and standpipe, it is to avoid cannot loosen at articulation, or force to cause the problems such as other wire connection position leakages when dismantling.But the deficiency that this plugging device yet suffers from is: during use, this plugging device is arranged in purging stake, closure is realized by the expansion of the first rubber ring, need one during closure and hold fixed handle, one holds ratchet spanner and carrys out rotating tension bar, avoid pull bar and stifled handle generation common rotation, bring very big inconvenience when operation to workman, even need two people could carry out rotating operation；The port plugging module of this plugging device includes upper lining and second rubber ring of upper lining excircle of push pipe excircle, after plugging device will purge stake closure, the pressure that plugging device can be produced by combustion gas upwards, only blocked with the contact internal walls purging stake by the first rubber ring and the second rubber ring, pressure easily makes plugging device entirety upward displacement, when the curved logical place of the first rubber ring pan position tee T, the effect of closure i.e. can not be realized.
Utility model content
The purpose of this utility model is to provide combustion gas purging stake stopper, and occur during to solve closure operates the problem that inconvenient and whole plugging device is shifted over because of gaseous-pressure effect.
For reaching above-mentioned purpose, basic technology scheme of the present utility model is to provide combustion gas purging stake stopper, including the support set of hollow, the adjusting lever through support set center, expansion sleeve, adjusting lever includes extension, linkage section and the swelling section that diameter is sequentially reduced, the end of swelling section is provided with anti-withdrawing nut, and linkage section is provided with external screw thread；Support set includes extension and connecting portion, junction between extension and connecting portion is provided with locking screw, extension is sheathed on the extension of adjusting lever and the end of adjusting lever extension is positioned at outside extension, the connecting portion of support set is set on the linkage section of adjusting lever, and the connecting portion of support set is provided with the female thread that the linkage section with adjusting lever matches；Expansion sleeve is located on the excircle of swelling section and between anti-withdrawing nut and the connecting portion of support set.
In technique scheme, during use, the swelling section of adjusting lever is sequentially passed through extension and the connecting portion of support set, make the linkage section external screw thread of adjusting lever be connected with the screw-internal thread fit of support set connecting portion；Again expansion sleeve is enclosed within the swelling section of adjusting lever, then anti-withdrawing nut is arranged on the end of adjusting lever swelling section；Then whole stopper is inserted in purging stake, make the locking screw of support set be connected with the threaded engagement in purging stake.Rotate adjusting lever, adjusting lever i.e. can be made to relatively rotate with support set, and support set is fixing, the swelling section being positioned at the adjusting lever outside support set will shorten, now expansion sleeve can extruding by the end of anti-withdrawing nut and support set connecting portion, expansion sleeve is made to expand, thus will purging stake closure.
The beneficial effects of the utility model are, are blocked purging stake by the expansion of expansion sleeve, reach intended closure purpose；When closure, because of support set external screw thread and purging stake stable connection, during the pressure that stopper is produced by combustion gas upwards, whole stopper will not be made to move up and down in purging stake, do not interfere with plugging effect, after expansion sleeve swelling so that what whole device was more firm is fixed in purging stake；During closure, because of support set external screw thread and purging stake stable connection, workman has only to a hands and rotates adjusting lever by instrument, compared with background technology needs two hands operations, the efficiency of closure is improve to workman while bringing great convenience, in maintenance of speedily carrying out rescue work, greatly improve work efficiency, quickly provide the user and just commonly use gas.
The preferred version 1 that the improvement of base case is obtained: the extension end of support set is additionally provided with the rear enclosure removably connected；Rear enclosure can make the end of adjusting lever extension be closed between support set and rear enclosure, it is to avoid other people rotate adjusting lever privately, occurs that the phenomenon of adjusting lever is not sternly even extracted in closure during making closure.
The preferred version 2 that the improvement of base case is obtained: between anti-withdrawing nut and expansion sleeve, be equipped with pad between the connecting portion of support set and expansion sleeve；Two pads are separately positioned on the two ends of expansion sleeve; when expansion sleeve stress; expansion sleeve directly contacts with pad; for the connecting portion of direct and anti-withdrawing nut and support set contacts; this structure makes expansion sleeve two ends stress evenly; swelling effect is more preferable, makes the lifting surface area at expansion sleeve two ends increase simultaneously, plays a protective role expansion sleeve.
Base case or preferred version 1 or preferred version 2 optimized the preferred version 3 obtained further: the extension end of adjusting lever is provided with the anti-skidding mouth being easy to clamping；When rotating adjusting lever, it is simple to the end of turning tool clamping adjusting lever extension, it is to avoid sliding phenomenon occurs, it is simple to quick rotation adjusting lever.
