Description
Technical field
This utility model belongs to gas pipeline and speedily carries out rescue work maintenance field, relates to a kind of gas pipeline and rushes to repair anti-misunderstanding device.
Background technology
Natural gas, as clean energy resource, can reduce the consumption of coal and oil, thus be substantially improved problem of environmental pollution, to this end, the use ratio of natural gas is wide, and be applied to every field., as the pipeline of transporting combustible gases, easily there is the situation of leakage in steel gas pipeline, and main cause is as follows: 1, due to the life-time service of pipeline, and above-mentioned pipeline meeting natural rust, electrochemical corrosion, slight crack and corrosion leakage phenomenon easily occurs in pipeline；2, owing to drilling, digging a well, the artificial fault reason such as piling, will also result in above-mentioned pipeline damage and leakage phenomenon；3, owing to such as natural disasters such as thunderbolts, also pipeline can be damaged.The maintenance activity accordingly, it would be desirable to carry out speedily carrying out rescue work.
But, gas facility is speedily carried out rescue work in maintenance process daily, there is also a lot of problem.Speedily carrying out rescue work in maintenance work gas facility is daily, be replaced indoor standpipe, need to close pressure regulating box operation, coverage of stopping the supple of gas or steam is big；Or low pressure RQ buried pipeline carries out draining, nitrogen flow in pipes is purged, it is necessary to outdoor is introduced the purging stake at pipe and separates with loose joint.Outdoor purging stake is longer because of service life, and mopping causes the gap between loose joint to be painted to fill up, cause great majority purging stake loose joint to loosen, easily cause the leakage of other wire connection positions when dismantling repeatedly；When changing a certain indoor standpipe, need to suspend the gas supply of other indoor standpipe in Zheng Dong building, the normal supply of impact.
In order to prevent drawbacks described above on current market, indoor standpipe and and outdoor introducing pipe at purging stake between tee T is installed, at tee T, be provided with plug, when needs operate, pull down plug, insert stopper, thus by indoor standpipe and the isolation of outdoor introducing pipe, it is to avoid large area is stopped the supple of gas or steam.Above-mentioned stopper includes adjusting lever, support set, expansion sleeve, and expansion sleeve is enclosed within adjusting lever tail end, by adjusting lever and the relative motion of support set thus drive expansion sleeve to tighten up, expansion sleeve cross-sectional area becomes big thus closed airway.The problem that there is currently is, 1, spanner can be random rotation, be easily misused during actual job, cause gas leakage, the lighter to cause gas losses, produce potential safety hazard, heavy then blast accident occurs, the life security of threat personnel and damage to property；2, speedily carrying out rescue work in maintenance process at gas facility, the expansion sleeve of adjusting lever lower end can be inserted into the inside of tee T, it is impossible to observe directly the state of closure from outside.
Utility model content
The purpose of this utility model is to provide a kind of gas pipeline stable, that operation is simple and reliable to rush to repair anti-misunderstanding device, prevents from misreading, it is to avoid arbitrarily rotate adjusting lever, and can be visually seen whether combustion gas blocks complete, reduces the potential safety hazard in repairing operation.
For reaching above-mentioned purpose; basic technology scheme of the present utility model is to provide a kind of gas pipeline and rushes to repair anti-misunderstanding device; including adjusting lever, support set, expansion sleeve; adjusting lever runs through support set; adjusting lever is connected with thread of supporting sleeves, and adjusting lever passes the part of support set and is cased with expansion sleeve, and adjusting lever is cased with one end of expansion sleeve and is provided with clamp device; adjusting lever free end is positioned at support set, and support set connects protected set near the threaded one end of adjusting lever free end；Clamp device is anti-withdrawing nut, and anti-withdrawing nut removably connects with adjusting lever.
When using such scheme, adjusting lever runs through support set, and adjusting lever is connected with thread of supporting sleeves, and adjusting lever passes the part of support set and is cased with expansion sleeve, and adjusting lever is cased with one end of expansion sleeve and is provided with clamp device.Adjusting lever can produce relative motion with support set by screw thread, threaded circumferentially rotating of adjusting lever is changed into axial movement, thus drives clamp device to move；When needs work, adjusting lever rotates and drives clamp device to move extrusion expansion set, so that expansion sleeve tightens up, the expansion sleeve cross-sectional area caused becomes big and then stifled stopped pipe road, successfully blocks.Adjusting lever free end is positioned at support set, adjusting lever free end is prevented to expose, it is effectively prevented the operation to adjusting lever of the external instrument, special instrument must be used could adjusting lever to be operated effectively, when avoiding maloperation or operation, adjusting lever is misunderstood, improve safety coefficient, decrease potential safety hazard.Meanwhile, when adjusting lever free end is positioned at support set, shows not have started and carry out blocking or block not exclusively；When adjusting lever free end flushes with the port of support set, then it represents that closure operation completes, can expression sealed condition clearly.Support set connects protected set near the threaded one end of adjusting lever free end, and adjusting lever free end is protected by protection set further, and supports to specific purpose tool rotation adjusting lever offer, prevents damage equipment.Clamp device is anti-withdrawing nut, and anti-withdrawing nut removably connects with adjusting lever, it is simple to the replacing of equipment and installation.
Anti-misunderstanding device is repaiied in combustion gas described in such scheme, can prevent from arbitrarily rotating adjusting lever, it is to avoid misread, and reduces potential safety hazard.
The preferred version 1 obtaining the improvement of base case, is provided with pad between anti-withdrawing nut and expansion sleeve, stress when pad will reduce expansion sleeve stress is concentrated, and improves service life.
The preferred version 2 that the improvement of base case is obtained; it is provided with joint in protection set; with described adjusting lever free end clamping bottom described joint, this joint is to support the use, during work with adjusting lever; after installing protection set; by complete with adjusting lever clamping for joint, now using instrument swivel, joint will drive adjusting lever to rotate together; so that expansion sleeve is by compression swelling, blocking pipe；Now joint should be taken out after closure is intact, place and appropriate position, do not have joint will be difficult to adjusting lever and operate, thus reach the purpose of anti-misunderstanding.
The preferred version 3 obtaining the improvement of base case, expansion sleeve is macromolecule new polyurethane material, and macromolecule new polyurethane has good compressive property, and anti-wear performance.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model gas pipeline rushes to repair anti-misunderstanding device embodiment.
Detailed description of the invention
