Description
Technical field
The utility model relates to pipeline maintenance technical field more particularly to a kind of online leak stopping structures of gas transmission pipeline.
Background technique
Almost it can all be related to the conveying of gas in all industrial production places；And gas leakage occurs in gas transmission pipeline
When, it generally requires to carry out leak stopping repairing again after closing pipeline.In particular for the leak stopping reparation of steam conveying pipe, due to
The gas of leakage is high-temperature steam, is easy to damage the worker of reparation, therefore is even more to require leak stopping reparation after closing pipeline.
However in process of production, once closedown of pipeline, few then influence production efficiency, a whole set of production equipment is then caused to be shut down greatly, it can not
Continue to produce.Therefore, it is badly in need of a kind of scheme that online reparation leak stopping can be carried out to gas transmission pipeline, at present to reduce to production
Movable influence.
Utility model content
The technical issues of the utility model solves, which is to provide one kind, to carry out leak stopping reparation online to gas transmission pipeline
Leak stopping structure.
The technical scheme adopted by the utility model to solve the technical problem is as follows: the online leak stopping structure of gas transmission pipeline,
Including blow-down pipe, one end of blow-down pipe is socket end, and the other end of blow-down pipe is discharge end；It is defeated that the socket end is set in gas
It send the leak source of pipeline and surrounds the leak source, the socket end is connect by welding with gas transmission pipeline；In socket end
Valve is provided between discharge end.
Further, the socket end of blow-down pipe is set as and the consistent arc of gas transmission pipeline outer tube wall crooked radian
Groove.
Further, the blow-down pipe is straight tube.
Further, further including extension tube, the extension tube is removably connected to the discharge end of blow-down pipe.
Further, using flanged joint between extension tube and blow-down pipe.
Further, the extension tube is in bending-like.
The beneficial effects of the utility model are: the online leak stopping structure of gas transmission pipeline described in the utility model, is needle
After gas transmission pipeline gas leakage, online leak stopping reparation is carried out to leak source, without closing pipeline, pipeline is allowed to be in conveying with pressure
Working condition, normal production activity is hardly had an impact；It can guarantee and pipeline is carried out in leak stopping repair process
Production efficiency.
Detailed description of the invention
Fig. 1 is the schematic diagram of the online leak stopping structure of gas transmission pipeline described in the utility model；
Fig. 2 is the schematic diagram of blow-down pipe；
Fig. 3 is the cross-sectional view of Section A-A in Fig. 2；
In the figure, it is marked as blow-down pipe 1, socket end 2, discharge end 3, gas transmission pipeline 4, leak source 5, valve 6, arc groove
7, extension tube 8.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1 to Figure 3, the online leak stopping structure of gas transmission pipeline described in the utility model, including blow-down pipe
1, one end of blow-down pipe 1 is socket end 2, and the other end of blow-down pipe 1 is discharge end 3；The socket end 2 is set in air shooter
It is surrounded at the leak source 5 in road 4 and by the leak source 5, the socket end 2 is connect by welding with gas transmission pipeline 4；In socket end
Valve 6 is provided between 2 and discharge end 3.
It is as follows using the specific leak stopping repair process of the online leak stopping structure of above-mentioned gas conveyance conduit:
Firstly, the valve 6 on blow-down pipe 1 is fully opened, then socket end 2 is covered on to the phase on gas transmission pipeline 4
The periphery for answering leak source 5 makes from the gas that leak source 5 leaks out by temporarily discharging after blow-down pipe 1 from discharge end 3；Then, it will be socketed
End 2 is welded to connect with gas transmission pipeline 4, and is kept the welding of 2 complete cycle of socket end complete and guaranteed sealing effect；Finally close again
Valve closing door 6.So far the leak stopping reparation to corresponding leak source 5 can be completed.Certainly, without loss of generality, after above-mentioned reparation, entirely put
The structures such as blank pipe and valve will be retained on gas transmission pipeline 4 and form integral structure.
It is above-mentioned when socket end 2 to be covered on to the periphery of leak source 5, should make 2 surface of socket end as far as possible with gas transmission pipeline 4
Outer tube wall fitting, be subjected to so as to subsequent.Also, socket end 2 can should cover completely entire leak source 5, accordingly
It is then that the caliber of selected blow-down pipe 1 is required to be chosen accordingly according to the size of leak source 5.Furthermore, it is contemplated that usual feelings
Gas transmission pipeline 4 is at round tube under condition, be preferably arranged in the utility model thus blow-down pipe 1 socket end 2 be set as with
The consistent arc groove 7 of 4 outer tube wall crooked radian of gas transmission pipeline, to ensure socket end 2 and 4 outer tube wall of gas transmission pipeline
It is bonded effect.
More specifically, the blow-down pipe 1 in the utility model may be configured as straight tube structure, and its length is settable relatively
It is short, it is relatively small to stay in the entire plugging structure on gas transmission pipeline 4 after leak stopping is repaired.
Furthermore, it is contemplated that according to blow-down pipe 1 it is shorter, it is direct from the discharge end 3 of blow-down pipe 1 and when being straight tube structure
The gas of exclusion may generate certain interference to leak stopping repair personnel and even injure.For example, if leaked gas is height
When warm steam, it is likely that damaged to the operating personnel of leak stopping reparation.For this purpose, being further provided with extension in the utility model
Pipe 8, the extension tube 8 are removably connected to the discharge end 3 of blow-down pipe 1；In this way, can lead in carrying out leak stopping repair process
It crosses extension tube 8 gas being discharged from discharge end 3 is extended into comparatively safe position and discharge, to improve the peace of operating personnel
Quan Xing；And it can be completed in leak stopping repair, and after closing corresponding valve 6, then extension tube 8 is dismantled.
More specifically, flange connection can be used between blow-down pipe 1 and extension tube 8, to realize detachable link；Accordingly
, it can be preset with corresponding ring flange in discharge end 3, while corresponding one end is also preset with ring flange in extension tube 8.
In addition, extension tube 8 may be alternatively provided as bending-like, the direction after bending can be used to discharge leakage as needed in this way
Gas.
