Description
Technical field
The invention belongs to air-leakage test fields, and in particular to a kind of air-leakage test plugging device.
Background technique
The main positions that gas pipeline is easy to produce leakage are at connecting flange, threaded connection place, at valve, pressure with
Leakage caused by situations such as easy position changed of temperature and pipeline itself corrode；The most commonly elbow of pipeline, in pipe
Leakage situation on road is mainly caused by damage from third-party or pipe perforation.The leakage of gas is few then to influence human health, wave
Take the energy；It is heavy then, will lead to explosion, cause the security of the lives and property, bring about frightful disaster.
So needing to detect the air-tightness of gas pipeline, now current air-leakage test plugging device is mainly used
Some mechanical structures are placed in pipeline, by blocking pipe, are improved air pressure, are reflected pipeline by detecting the variation of air pressure
Air-tightness, need manually to be monitored, discovery is needed the later period to repair and blocked when having leakage after sensing, it is difficult at that time
It places under repair to pipeline.
Summary of the invention
It is right after the air-leakage test to solve gas pipeline the invention is intended to provide a kind of air-leakage test plugging device
The problem of being blocked in time at leakage.
In order to achieve the above object, base case of the invention is as follows：A kind of air-leakage test plugging device, including pipeline
With several detection plugging devices, in the detection plugging device pipe laying, the detection plugging device includes bracket and closure
One end of piece, the bracket is mounted in inner wall of the pipe, and the other end of bracket is free end, and bracket is parallel with the section of pipeline,
The plugging sheet is hinged in inner wall of the pipe on one side, and plugging sheet is parallel to the free end of the side contact bracket of conduit axis,
The plugging sheet is equipped with viscose glue, and the inner wall of the pipe is smooth.
The principle of base case：When operation, bracket and plugging sheet are mounted on inside pipeline, by the one side of plugging sheet and branch
The end thereof contacts of frame make plugging sheet be in vacant state；Then by Pipe installing in the pipeline loop of gas, gas is in pipeline
Interior circulation makes plugging sheet be in equilibrium state, frame is on bracket when gas flows；Occur on the pipeline of the lower section of plugging sheet
When leakage, extraneous atmospheric pressure is lower, and gas is flowed out from leakage place, and the flow direction variation of gas drives plugging sheet constantly to lean on
Nearly inner wall of the pipe, the surface of plugging sheet are bonded with smooth inner wall of the pipe；Existing gas or sky between plugging sheet and pipeline
Gas can squeeze out, plugging sheet is bonded completely with pipeline, the viscose glue that plugging sheet is equipped under the effect of pipeline air pressure inside from leakage place
With inner wall of the pipe close adhesion.
The advantages of base case：1, one end of plugging sheet is mounted in inner wall of the pipe, the free end of another end in contact bracket,
Plugging sheet is allowed to be in vacant state, when inner wall of the pipe leaks, flow direction and draught head using gas, by plugging sheet
Attract downwards, be bonded inner wall of the pipe, realize the detection to leakage and closure two at leakage are acted on；2, the setting energy of bracket
When enough guarantees do not occur leakage, plugging sheet contacts bracket, and plugging sheet is allowed to be in vacant state；3, two adjacent edges of plugging sheet are allowed
It is parallel to pipeline section, is to allow plugging sheet to be in equilibrium state, not flowed in pipeline by gas is influenced, and plugging sheet is made
Parallel with the flow direction of gas, when pipeline being avoided not occur at leakage, plugging sheet is bonded with inner wall of the pipe；4, it is set on plugging sheet
There is viscose glue, and inner wall of the pipe is smooth, after guaranteeing that plugging sheet and pipeline fit closely, the flowing of gas will not allow plugging sheet and pipe
The separation of road inner wall.
Preferred embodiment one：It further include contact sensor as the preferred embodiment of basic scheme, the contact sensor is fixed
Rack-mount, the connection between the bracket and inner wall of the pipe is hinge connection.Pass through above-mentioned setting, contact sensor sense
It should be to when contacting plugging sheet, bracket remains static；When inductor is not sensed by contact plugging sheet, plugging sheet is rotated down
To at leakage, at plug leak, contact sensor can control holder pivots, and bracket presses down on plugging sheet, quickly allow closure
Piece is bonded with inner wall of the pipe, further avoids the flowing of gas that plugging sheet is allowed to separate again with inner wall of the pipe.
Preferred embodiment two：Preferably one preferred embodiment, the bracket are flexible support, the bracket and hinged
The tangent line for cutting circle of point is in 20 degree, and the plugging sheet is mounted on bracket and the side of tangent line in obtuse angle.Pass through above-mentioned setting, bracket
Angle setting keep the vacant state of plugging sheet more stable, below the plugging sheet when leakage of corresponding inner wall of the pipe, faster
To being blocked at leakage；Hinged bracket can return to original position under manual operation, can continue to realize inspection after returning to original position
It surveys and blocks；For bracket flexible when pressing plugging block, the shape of bracket can be consistent with the amplitude of inner wall of the pipe, keeps plugging block fast
Speed is bonded with inner wall of the pipe.
Preferred embodiment three：Preferably two preferred embodiment, the stent surface smoothing, the plugging sheet is can be with
The material that smooth bracket and inner wall of the pipe are close to.By above-mentioned setting, plugging sheet can be with smooth bracket and inner wall of the pipe
It is close to, so that inversion is also worked normally in the detection plugging device of inner wall of the pipe upper end, plugging sheet is allowed to be not influenced by gravitation, according to
It can so be close to inner wall of the pipe, at plug leak.
Preferred embodiment four：Preferably three preferred embodiment further includes detection plugging device, the contact sensor
Connecting detection plugging device.By above-mentioned setting, if not contacted with plugging sheet by contact sensor, contact sensor reflection is arrived
It detects on plugging device, embodies relevant position and leak, when maintenance, need to only observe detection plugging device can grasp gas
Occur the place leaked in pipeline, corresponding position is repaired, it is convenient and efficient, centralized maintenance may be implemented.
Preferred embodiment five：Preferably four preferred embodiment, the detection plugging device are evenly distributed in pipeline
Interior, the plugging sheet covers inner wall of the pipe.By above-mentioned setting, it can guarantee that detection is covered in entire gas pipeline blocks dress
It sets, guarantees anywhere temporarily being blocked at leakage occurs leakage part and have plugging sheet in pipeline, it is possible to reduce gas
Leakage, can also be to avoid the generation of other perils.
