Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Example one

As shown in fig. 1-4, the utility model provides a pair of refute takeover for pipeline is restoreed, including body 10 and the refute connector 11 of setting at body 10 both ends, refute connector 11 including refute section 12 and the linkage segment 18 of being connected with body 10, refute section 12 inboard and be equipped with annular expansion body 14, refute connector 11 inside wall and be equipped with annular groove 13, annular expansion body 14 imbeds in annular groove 13, during the application, measure the length that former pipeline 20 damage section needs to be amputated in advance, cut body 10 according to this length, and fix two sets of refute connector 11 respectively at the body 10 both ends after cutting, after amputating former pipeline 20 damage section, refute connector 11 with body 10 both ends and cup joint respectively on the port that cuts of former pipeline 20, wherein, refute section 12 and annular expansion body 14 cover and establish on former pipeline 20, and annular expansion body 14 forms sealedly through the inflation between former pipeline 20 and refute connector 11.

Specifically, set up annular inflation body 14 in refuting the section 12 inboard, refute the back on former pipeline 20 of connector 11 and annular inflation body 14 cup joint, form sealedly between former pipeline 20 and refute connector 11 through the inflation of annular inflation body 14, the shutoff is realized to the fluid, fluid in the former pipeline 20 can be carried along former pipeline 20, need not to cut off the flow or shorten the time of cutting off the flow to the pipeline, then follow-up can refute connector 11 and former pipeline 20 in refuting the section 12 outside of connector 11 and weld or weld refute connector 11, fluid has been avoided leaking, influence the butt fusion or the welding of pipeline, compare in prior art, when carrying out pipeline rehabilitation, need not to cut off the flow to the pipeline, the effectual influence that reduces pipeline rehabilitation to peripheral region resident, avoid fluid to leak the butt fusion or the welding that influences the pipeline.

Further, refute the takeover outside and annular groove 13 relative position and be equipped with annular bulge 16, through refuting the takeover outside and set up annular bulge 16, avoid annular groove 13 to reduce the structural strength who refutes the takeover, when the former pipeline 20 of butt joint, can carry out the tractive through annular bulge 16 to refuting the takeover head 11 simultaneously.

Further, when using on water supply pipe or drainage pipe, annular inflation body 14 is the water-swelling rubber of annular, wherein, water-swelling rubber of annular is meeting automatic inflation after water, thereby form sealedly between the gap of refuting and connecing section 12 and former pipeline 20, annular groove 13 enlarges gradually towards inboard opening, water-swelling rubber of annular is at the inflation in-process, extrude former pipeline 20 one side, for avoiding water-swelling rubber of annular in advance to meet water-swelling rubber, water-swelling rubber of annular can adopt sealed package alone, and when cup jointing former pipeline 20, water-swelling rubber of annular again puts into.
