Description
Technical field
The utility model belongs to pipeline field, is related to a kind of pipe plugging, especially a kind of gas pipeline temporary plugging.
Background technique
Currently, pipeline has become important a part of urban infrastructure construction, it has in terms of transport
High efficiency and convenience is lived closely bound up with people, with the big quantization that pipeline is laid with, pipeline fault also Shi Youfa
It is raw, during relocating and repair in the municipal administration being related in municipal pipeline engineering at present, backend user is used in order to reduce
Adverse effect, it is often necessary to which non-stop plugging operation is implemented to running pipeline.
Non-stop plugging operation is usually to open up plugging hole in the upstream and downstream position of maintenance pipeline, and block head is placed into pipeline
In blocked, establish bypass line and make it possible to repair replacement while normal use.
It is moved in engineering in the repairing or change of gas pipeline, plugging hole is often arranged on the tube wall of pipeline, thus
Increase the difficulty of closure.The existing apparatus structure for blocking on tube wall is complex, install it is relatively complicated and
Leakproofness is poor.
By the retrieval to patent document, patent document identical with present patent application is not found.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide that a kind of structure is simple, facilitates installation, sealing
Property strong, the gas pipeline temporary plugging that is easily achieved.
The utility model solves its technical problem and adopts the following technical solutions to achieve:
A kind of gas pipeline temporary plugging, it is characterised in that: including plugging block, air bag and seal gasket are blocked, it is described
Plugging block be cylindrical block, closure air bag is set on the outer wall of the cylindrical block, the closure air bag be circular ring shape
Structure is provided with the groove docked with pipeline end face in the outer rim of cirque structure, seal gasket is provided on groove,
It is provided with stomata on the air bag, valve is provided at stomata.
Moreover, further including gas leakage alarm, gas leakage alarm is embedded on the upper surface of the plugging block.
Moreover, further including handle, handle is installed in the plugging block.
The advantages and positive effects of the utility model are as follows:
1. gas pipeline temporary plugging, in use, this closure groove is docked on pipeline, seal gasket is in addition to close
Certain skeleton function is also played other than the effect of envelope, avoids making this closures not limit at pipeline fortunately because air bag is excessively soft
Problem；Then, starting inflator pump inflates air bag, completes installment work of this closure at plugging hole.It is convenient and efficient, it can be right
The closure mouth of different bores is blocked, and installation effectiveness is substantially increased.
2. gas pipeline temporary plugging can make the plugging tool for combustion gas inspection by the setting of gas leakage alarm
The function of survey avoids causing to block not tight problem because of air bag gas leakage.When there is gas leakage, on gas leakage alarm
The induction of gas sensitization area, is then alarmed as the buzzer built in it, enhances the use reliability of this closure.
3. gas pipeline temporary plugging facilitates taking for closure by the setting of handle, it is conducive to construction.
4. design is scientific and reasonable for the utility model, have structure is simple, facilitate installation, leakproofness it is strong, using being reliable, easy to
The advantages of realization is a kind of gas pipeline temporary plugging with higher innovation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model is connect with pipeline；
Fig. 2 is the structural schematic diagram of the utility model plugging block and gas leakage alarm assembly.
Description of symbols
1- pipeline, 2- block air bag, 3- seal gasket, 4- handle, 5- plugging block, 6- gas sensitization area, 7- buzzer.
Specific embodiment
The embodiments of the present invention are further described below in conjunction with attached drawing:
A kind of gas pipeline temporary plugging, innovation are: including plugging block 5, blocking air bag 2 and seal gasket
3, the plugging block is cylindrical block, closure air bag is set on the outer wall of the cylindrical block, which is
Cirque structure is provided with the groove docked with 1 end face of pipeline in the outer rim of cirque structure, sealing is provided on groove
Rubber mat is provided with stomata on the air bag, valve is provided at stomata.
Further include gas leakage alarm, gas leakage alarm is embedded on the upper surface of the plugging block.
Further include handle 4, handle is installed in the plugging block.
In use, this closure groove is docked on pipeline, seal gasket also plays one other than the effect of sealing
Fixed skeleton function avoids the problem that limiting this closure at pipeline fortunately because air bag is excessively soft；Then, start inflator pump pair
Air bag inflation, completes installment work of this closure at plugging hole.It is convenient and efficient, can the closure mouth to different bores seal
It is stifled, substantially increase installation effectiveness.By the setting of gas leakage alarm, the plugging tool can be made for the function of coal gas detection,
It avoids causing to block not tight problem because of air bag gas leakage.Gas sensitization when there is gas leakage, on gas leakage alarm
Area 6 incudes, and is then alarmed as the buzzer 7 built in it, enhances the use reliability of this closure.
Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with
Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can
Can, therefore, the scope of the utility model is not limited to the embodiment and attached drawing disclosure of that.
