Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, it is detailed now to compare accompanying drawing
Illustrate specific embodiment of the present utility model.
With reference to shown in Fig. 1, Fig. 2, the temporary blocking device after pipeline tapping in one preferred embodiment of the utility model
Including closeouts, closeouts 1 include being used for the closure main body 11 for blocking the endoporus 21 of pipeline 2, generally, block main body 11
Outer ring be provided with O-ring seal, closeouts 1 can carry out temporary plugging after to the extra large press and open holes of pipeline 2.
When carrying out extra large 2 plugging holes operation of pipeline, closeouts 1 are pre-installed in the emitter 5 of closeouts 1.It is right
During extra large 2 press and open holes of pipeline, straight by threeway 3 stretches 31 sets of pipe and is set to the position of pipeline 2, in threeway 3 with directly to stretch pipe 31 vertical simultaneously
On the branch pipe 32 of connection it is corresponding installation slide valve 4, the mounting opening machine on slide valve 4, slide valve 4 open after, tapping machine by
Through hole corresponding to branch pipe 32 carries out perforate to pipeline 2.
After the extra large press and open holes of pipeline 2 are completed, in the case of keeping the closing of slide valve 4, tapping machine is removed.Underwater installation
The upper emitter 5 of closeouts 1 passes through slide valve 4 and machinery three to slide valve 4, transmitting closeouts 1 on slide valve 4, are then opened
Logical 3, the extra large projected depth of pipeline 2 is then entered by position of opening, with reference to shown in Fig. 5 to Fig. 7, then controls closeouts 1 to turn to, it is right
The endoporus 21 of pipeline 2 is blocked.
Preferably, as shown in Fig. 2 closeouts 1 also include the hemispherical target seeker for being arranged on closure main body 11 one end end
12, the stub end of target seeker 12 is connected with blocking one end of main body 11.When closeouts 1 enter perforate, where target seeker 12
One end is introduced into perforate, and hemispheric target seeker 12 can avoid closeouts 1 from being contacted when turning to the endoporus 21 of pipeline 2 at favourable angle
Hit, meanwhile, hemispheric target seeker 12 also allows for closeouts 1 allows target seeker 12 and the bottom of pipeline 2 to contact when turning to, and is
Closeouts 1 are supported, avoid center of gravity have it is big rise and fall, be easily controlled steering position.
Further, hit to there will not be Li Jiao when allowing closeouts 1 to be removed from endoporus 21 with miscellaneous part, closeouts
1 both ends are respectively provided with hemispheric target seeker 12.
With reference to shown in Fig. 2 to Fig. 4, in certain embodiments, closeouts 1 are provided with iron chips cleaning device 6, and iron filings are cleared up
Device 6 is applied in closeouts 1, can enter in closeouts 1 when the endoporus 21 of pipeline 2 turns to the sealing station production in closeouts 1
Raw iron filings are cleared up, lift-off seal effect.
Iron chips cleaning device 6 includes being used for the plate for being arranged on the clamping plate 61 of closure main body 11 one end and being arranged on clamping plate 61
Brush 62, clamping plate 61 are installed for scrubbing brush 62, are supported for scrubbing brush 62.Scrubbing brush 62 is extended from clamping plate 61 to the outer ring of closeouts 1,
When closeouts 1 fill in the sealing of perforate rear steering, to allow scrubbing brush 62 to clear up the iron filings of the correspondence position of endoporus 21 of pipeline 2, make envelope
The endoporus 21 of the stifled energy of main body 11 blocking pipe 2.
Target seeker 12 and iron chips cleaning device 6 with reference to shown in Fig. 5 to Fig. 7, are blocking positioned at same one end of closure main body 11
When part 1 enters perforate, one end where iron chips cleaning device 6 will be introduced into perforate, and then can be right when closeouts 1 turn to
The iron filings cleaning of the bottom of pipeline 2.After closeouts 1 turn in place, iron chips cleaning device 6 is just by the iron filings of the downside of closeouts 1
Cleaning is completed, and allowing closeouts 1 not have iron filings in sealing influences sealing property.
Preferably, clamping plate 61 is arranged on target seeker 12, and deviates closure main body 11, and one is formed between closure main body 11
Determine space to deform for scrubbing brush 62.In other embodiments, also allow for iron chips cleaning device 6 and be set directly at the closure correspondence of main body 11
End, in addition, also target seeker 12 can be cancelled.
In certain embodiments, scrubbing brush 62 includes the brush net being knitted to form by brush line, and brush line is usually polytetrafluoroethylene
Material.Further, scrubbing brush 62 includes multilayer brush net, has prevented iron filings from missing, has influenceed the sealing property of closeouts 1.At other
In embodiment, the laminated structure of scrubbing brush 62 or elasticity, when being turned to closeouts 1, the iron filings in pipeline 2 are blown off.
With reference to shown in Fig. 3, Fig. 4, the border profile pair of the profile and closure main body 11 on the one side of scrubbing brush 62 away from clamping plate 61
Should, when closeouts 1 turn to, the iron filings of sealing station are cleared up using scrubbing brush 62, when closeouts 1 redirect to sealing station,
Scrubbing brush 62 can just clear up completion, and not have interference between the inwall of pipeline 2.
Certainly, when scrubbing brush 62 deviates the end face certain distance of closure main body 11, the one side of scrubbing brush 62 away from clamping plate 61 is arrived
The distance for blocking the center of main body 11 is also greater than the radius for blocking main body 11.The distance that scrubbing brush 62 deviates with closure main body 11 can be with
For the deformation storage of scrubbing brush 62 after closeouts 1 complete closure.
In certain embodiments, scrubbing brush 62 is curved or fan-shaped, and arc-shaped side can be allowed right positioned at the downside of closure main body 11
The iron filings cleaning of the bottom deposit of pipeline 2.Preferably, scrubbing brush 62 is in semicircular, is collectively forming with the end of clamping plate 61 and closeouts 1
Face is kept out, clears up iron filings to side in the downside of closeouts 1.
Further, clamping plate 61 is curved, and scrubbing brush 62 is circumferentially disposed along clamping plate 61.In other embodiments, clamping plate 61
Also can be rounded etc. other shapes, scrubbing brush 62 can be supplied to install and scrubbing brush 62 can be allowed to clear up iron filings.Accordingly, scrubbing brush
62 are alternatively annular, can not have to the circumferential steering direction for considering closeouts 1.
It is to be appreciated that above-mentioned each technical characteristic can be used in any combination and unrestricted.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
