Abstract

The utility model relates to a rush repair casing tube without water cut-off, which is composed of a sealing sleeve body, a sleeve ring, a sealed body and a fastening piece, wherein, a two parts split and amplexis structure which is matched with both ends of the sleeve ring is used by the sealing sleeve body, the part of the sealed body is deformed by the fastening pieces to tightly contact with the sealing sleeve body and a water tube to form sealing. The rush repair time is shortened by the utility model, the operation is simple, the sealing effect is good, and the loss caused by cutting off water supply in large area for a long time during the rush repair is avoided.

Description

Rush-repairing case pipe without water cut-off

The utility model relates to the repairing sleeve pipe of pipeline maintenance technical field, particularly a kind of water pipe.

, when pipeline breaking or damage fugitive water (or other liquid), the control valve of pipeline need be closed, anti-sealing continuously outflows, and near the residual water the pipeline must be drained then in the past.Be processed into out the limit sleeve pipe, be enclosed within the pipe leakage place with steel plate, be welded into integral cannula then, fill the slit of sleeve pipe and pipeline enclosure again with cement, treat the dried solid back of cement (generally needing tens hours), could recover normal water supply.Like this, not only the operation repairing is complicated, labor intensity is big, maintenance expenses is high, and the water stopping time that causes is long, has a strong impact on pipe network user's production and life.In addition, the weld seam of steel plate is corroded easily, adds that the sealing of cement fill to belong to rigid seal, and reason such as improper or vibration causes to break once more and leaks because of process treating easily.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part and provides a kind of structure light and handy compact, simple to operate, good seal performance, the repairing sleeve pipe of not cutting off the water that the repairing time is short.

The purpose of this utility model is achieved by the following technical solution: the repairing sleeve pipe of not cutting off the water comprises big envelope body and the fastening piece of splitting into two thereof, is funnel shaped big envelope body two end part and constitutes sealing by Sealing, the collar and fastening piece and by the repairing pipeline outer wall.When pipeline breaks down when leaking, do not cutting off the water, do not draining under the situation of water, directly the big envelope body of two halves is encircled at the pipe leakage place, the collar is inserted at two ends, make the tight obvolvent of big envelope body do radially fixing and sealing earlier with fastening piece, tighten up the collar by the both sides fastening piece then, the seal at big envelope body two ends is compressed, realize axial seal, finish the sealing repairing at the place that leaks.

By adopting above-mentioned structure, make the utility model under the situation that need not cut off the water and drain water, can save the repairing time to breaking or damaging the water pipe that leaks and rush to repair; Repairing need only manual tool, and simple to operate, favorable sealing effect has shortened the repairing time, this be prior art can't be obtained.

Fig. 1 is the structural representation that partly cuts open of the present utility model.

Below in conjunction with drawings and Examples the utility model is described in further detail.

With reference to Fig. 1, in the present embodiment big envelope body 3 be lateral halves to opening structure, two big envelope bodies 3 are encircled on water pipe 6, and by each bolt and nut of two groups, 4,9 work is radially fastening up and down, be the effect of guaranteeing to seal, be placed with pad 5, water can not spilt from the amplexis seam on the mating face of two big envelope bodies, 3 amplexis.Seal 7 adopts " O " RunddichtringO, places between big envelope body 3 ends and the water pipe 6, and in the present embodiment, big envelope body 3 engages rearward end and is funnel shape.The collar 1 of garden tubular inserts big envelope body 3 end inwalls, form wedge-like engagement, push " O " RunddichtringO between them, and axially fasten by tightening up the 4 groups of bolt and nuts 2,8 that are through on the collar 1 and the big envelope body 3, make " O " RunddichtringO local deformation, closely contact with big envelope body 3 with water pipe 6 outer walls, form sealing.In addition, the collar 1 also can adopt the outer surface that is the truncated cone, is convenient to overlap the end of inserting big envelope body 3, makes the tightening bolt nut at 2,8 o'clock, compresses the better effects if of seal 7, seals tighter.

Member of the present utility model can be formed by the spheroidal graphite cast-iron casting, and also the useable glass steel is compressing, and it is lightly compact to have structure, and the repairing operating time is short, the advantage of good sealing effect etc.

Claims

1, a kind of repairing sleeve pipe of not cutting off the water comprises big envelope body and the fastening piece thereof split into two, it is characterized in that being funnel shaped big envelope body two end part and constitutes sealing by Sealing, the collar and fastening piece and by the repairing pipeline outer wall.

2, repairing sleeve pipe according to claim 1 is characterized in that described collar profile is the truncated cone.
