Background technique
Pipeline broke down or when taking over operation, usually needed to stop to keep in repair behind the conveyance conduit medium again in the past, and this mode has influenced ordinary production and life.In the last few years, for fear of this disadvantage, a kind of maintenance tool that does not stop the pipeline conveying having occurred is perforate with pressure and blocking device, wherein blocking device mainly is made of parts such as circular leather cup formula plugging device, company's case, sandwich valve, bases, but because unreasonable structure, there is poorly sealed close, problem such as the life-span is short.
Summary of the invention
The utility model be used for solving the defective that existing plugging structure exists and provide a kind of simple in structure, easy to use, the life-span long, the online non-stop plugging device of pipeline of good sealing effect.
Problem described in the utility model is realized by following technological scheme:
The online non-stop plugging device of a kind of pipeline, it comprises plugging device, bell jar 14, frame 15, valve 16, bypass valve 17, valve plate 18, middle cover 20, saddle 21, frame epicoele 23 compositions, described plugging device comprises overcoat 1, center-pole 2, fixed cover 3, trim ring 4, L RunddichtringO 5, horse shoe shaped spare 6, pin 7, front rod 8, bull stick 9, back link 10, circular leather cup 11, key 12, guide plate 13, wherein, overcoat 1 is contained on the center-pole 2 and is screwed on the horse shoe shaped spare 6, and fixed cover 3 is contained in center-pole 2 outsides and fixedlys connected with guide plate 13; One end of front rod 8, bull stick 9, back link 10 and guide plate 13 flexibly connect, and the other end and circular leather cup 11 flexibly connect; On frame 15, be provided with a spanner, can control the keying of valve plate 18; Saddle 21 is fixed on the composite pipe 22, and middle cover 20 is loaded on the composite pipe 22, and frame 15 is installed on the middle cover 20.
The online non-stop plugging device of above-mentioned pipeline, described L RunddichtringO 5 is the 3-5 millimeter apart from the distance at place, horse shoe shaped spare 6 convex edges.
The online non-stop plugging device of above-mentioned pipeline, described valve plate 18 tops are provided with an O-ring seals 19.
The plugging device that the utility model provides adopts quadratic crank mechanism, and therefore folding flexible, good sealing effect leakage phenomenon can not occur.The whole operation process realizes that in frame plugging device moves up and down, and need not turn, and disrepair phenomenon can not take place, so long service life, good sealing effect.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Each unit number is respectively among the figure: 1 overcoat, 2 center-poles, 3 fixed covers, 4 trim rings, 5 L RunddichtringOs, 6 horse shoe shaped spares, 7 pins, 8 front rods, 9 bull sticks, 10 back links, 11 circular leather cups, 12 keys, 13 guide plates, 14 bell jars, 15 frames, 16 valves, 17 bypass valve, 18 valve plates, 19 O-ring seals, 20 middle cover, 21 saddles, 22 composite pipes, 23 frame epicoeles.
The utility model is an adjunction arm or use when changing pipeline on pipeline.At first with two online non-stop plugging devices, place respectively and wait to keep in repair the pipeline two ends, plastics saddle 21 is welded on the steel skeleton plastic clad pipe 22 that connects arm in advance, the middle cover 20 of screwing on, frame 15 is sleeved on the middle cover 20, loads onto bell jar 14 and promptly assemble and finish.During work, turn on bell jar 14, put into the punching machine perforate after because the pressure of conveying gas compresses the valve plate 18 of closing, valve plate 18 and O-ring seals 19 are sealed conveying gas, at this moment, gas still flows out from composite pipe 22.On horse shoe shaped spare 6, be inserted in L RunddichtringO 5, the trim ring 4 of packing into, center-pole 2 usefulness pins 7 are connected on the fixed cover 3, and overcoat 1 is contained on the center-pole 2 and is screwed on the horse shoe shaped spare 6.Fixed cover 3 welds together with guide plate 13, and key 12, horse shoe shaped spare 6 are contained on the fixed cover 3, because the leading role of key 12, horse shoe shaped spare 6 can only slide up and down on fixed cover 3 and can not rotate; One end of front rod 8, bull stick 9, back link 10 is contained in guide plate 13, and the other end is contained on the circular leather cup 11, guarantee this moment L RunddichtringO 5 apart from horse shoe shaped spare 6 convex edges 3-5mm the most nearby, the plugging device component-assembled is finished.The circular leather cup of plugging device is packed into after folding in the frame epicoele 23, tighten bell jar 14, this moment throttle down 16, open valve plate 18, the plugging device parts are put into composite pipe 22 bottoms, and at this moment, the circular leather cup 11 of plugging device struts automatically under the effect of front rod 8, back link 10 and bull stick 9, with the conveying gas blocking-up, gas flows out from bypass tube.Keep center-pole 2 motionless, rotating jacket 1, horse shoe shaped spare 6 rises along key 12, because the position-limiting action of trim ring 4, L shaped seal ring 5 is by spreading and compress, and the exposed steel wire of opening is sealed, open bypass valve 17, fed sheet of a media can deliver gas to the downstream by the bypass tube of another shutoff equipment.Carry out aforesaid operations simultaneously at the composite pipe the other end, such two shutoff equipment are used, and the pipe that can break in the middle of two equipment, seal and connect arm and operate.
The utility model is simple in structure, and is easy to use, not only is fit to gas medium, maintenance works such as the adapter on the pipelines such as also applicable oil, water, replacing valve.
