Abstract

The utility model relates to a conduct pipe emergency repair junction. A steel pipe with an appropriate length is dissected along the longitudinal direction. Both sides of a semicircle which is cut are respectively welded with iron plates 4 with the same length. Both ends of the steel pipe is welded with flanges 1. Another four flanges 7 matched with the flanges 1 are arranged. During the installation, a rubber strip is bedded between the iron plates 4. A rubber ring is bedded between the flange 1 and the flange 7. The conduct pipe emergency repair junction with the above structure has the advantages of convenient installation, quick leakage protection, good sealing effect and fast first-aid repair speed.

Description

The pipe first-aid joint

1, technical field

The utility model relates to city supply water pipeline maintenance technique field, relates in particular to a kind of pipe clamp of rushing to repair usefulness.

2, background technique

The city supply water pipeline material adopts ductile iron pipe, reinforced concrete cement pipe mostly.Pipe leakage, way commonly used is to be rolled into shroud ring with iron plate to wrap on the impaired pipeline section, mouth is beaten with cement in both sides, treating that cement reaches after the set strength can water flowing, the time that general cement reaches set strength is 24 hours, this maintenance way is consuming time longer, and water stopping time is oversize, makes troubles to resident living.

3, summary of the invention

The purpose of this utility model is the deficiency that overcomes above-mentioned technology, and the pipe first-aid joint of a kind of convenient and quick construction, good sealing effect is provided.

The purpose of this utility model is achieved by the following technical solution: supposing that water supply line is impaired leaks, select one section steel pipe than the thick slightly bore of impaired caliber, at the pipe ends a slice self-control flange of respectively burn-oning, again this section steel pipe longitudinally one is sliced into halves, respectively weld the iron plate that the preceding paragraph proper width, length and steel pipe length are equal on the semicircle both sides of cutting, bore the hole of tightening up a screw at a certain distance, be lined with rubber strip between the iron plate.Make two flanges in addition by oneself, also will cut, match with the steel pipe nozzle flange from the centre, it should be noted that the otch of otch that these two flanges set up and original flange, the suitable distance that preferably staggers can more effectively be avoided leaking, and is lined with rubber ring between two flanges.

During use, to be able to take off by movable flange earlier, to rush to repair joint and be enclosed within on the damaged pipe, rubber strip is fastening with screw on lining between the iron plate of both sides, and rubber ring is cut into groove earlier, be enclosed within on the pipeline outer wall, after sticking with glue the agent sticker, other four semicircle flanges are enclosed within on the lead screw tightening the screw, rubber ring just tightly squeezes on tube wall like this, has stoped in all directions and has leaked.The whole process of repairing leakage is about about one hour.

Pipe first-aid described in the utility model joint is repaiied leakage method with tradition and is compared, and maximum characteristics are quick and convenient, and good sealing effect can adapt to various material pipelines, repaiies the leakage shortening of time and can retrieve many economic losses for the side of maintenance.

4, description of drawings

Fig. 1 is the schematic representation of pipe first-aid joint described in the utility model.

5, embodiment

With reference to Fig. 1, selected damaged pipe 3, supposing has one section crack 6 in the middle of the damaged pipe, selects one section steel pipe 2 than the thick slightly bore of pipeline 3 longitudinally to cut open, respectively be welded with on the semicircle both sides of cutting width suitably, the iron plate 4 that is equal to of length and steel pipe length, wrap on the pipeline 3, after lining is gone up rubber strip 5 between the iron plate 4 of centre, fastening with screw, serve as a contrast upward rubber ring between 2 liang of side flanges 1 of steel pipe and four supporting flanges 7, the jam-packed screw gets final product, and whole repairing process promptly finishes.

Claims

1, a kind of pipe first-aid joint, form by the steel pipe that length is suitable, it is characterized in that: steel pipe [2] is longitudinally cut open, respectively be welded with on the semicircle both sides of cutting width suitably, the iron plate [4] that is equal to of length and steel pipe [2] length, iron plate is drilled with screw hole on [4] at a certain distance, steel pipe [2] two ends are welded with flange [1], other has four flanges [7] that match with steel pipe [2] two end flange [1], on flange [1] and the flange [7] screw hole is arranged all, be lined with rubber strip [5] between the iron plate [4], be lined with rubber ring between flange [1] and the flange [7].
