Background
The heat pipe network often happens to leak in the heating season, especially for some buried pipe sections, the number of leakage times is relatively large, once the pipe section is leaked, the pipe section needs to be repaired, when the leaked pipe section is a main line with a large pipe diameter, a branch line and a branch line, the leaked pipe section needs to be cut off, a new pipe is welded, and when the pipe section is welded, the pipe section is cut off, no water can flow out, so that a long time is spent on water drainage and pressure relief to reach the welding condition during real construction, however, the time for closing a valve and water drainage and pressure relief is too long, so that a large amount of water resources are wasted, the normal life of residents is influenced, and even a large heat supply.
In addition, the heat primary pipeline at the present stage is in a high-temperature and high-pressure state during operation, and hot water leaked from the pipeline seeps out through a gap between the sleeve and the pipeline in the construction process, so that the construction personnel are easily scalded, and the personal safety of the construction personnel is damaged.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sleeve for heating power pipeline rush-repair can rush-repair impaired pipeline, protection constructor's personal safety fast.
In order to achieve the above object, the utility model discloses a telescopic concrete technical scheme for heating power pipeline rush-repair is:
a sleeve for use in a rapid repair of a thermal conduit, the sleeve comprising: the sealing device comprises two semicircular cylinders and ring buckles, wherein the semicircular cylinders are symmetrically arranged, the ring buckles are arranged on two sides of the outer sides of the semicircular cylinders along the axial direction, the ring buckles are used for connecting the two semicircular cylinders in a sealing manner through fasteners, through grooves are formed in the inner walls of the semicircular cylinders along the peripheries, sealing rubber strips are arranged in the grooves, the sealing rubber strips protrude out of the grooves and are in contact with the outer wall of a pipeline, and a sealed cavity is formed by the sealing rubber strips, the inner walls of the semicircular cylinders and the outer surface of the pipeline; in the construction process, hot water leaked from the pipeline flows out to enter the closed cavity, so that the hot water is prevented from flowing out of the sleeve to avoid scalding constructors, and meanwhile, conditions are provided for welding the sleeve and the pipeline.
Furthermore, the contact seam between the end face of the semicircular cylinder and the pipeline and the connecting seam between the two semicircular cylinders are welded by electric welding, and the sleeve is connected with the pipeline in a sealing way to have quite large pressure resistance so as to block the water leakage of the pipeline.
Furthermore, the sealing rubber strip is made of a temperature-resistant and pressure-resistant elastic material, so that the sealing performance is good, and hot water is effectively prevented from flowing out from gaps between the sleeve and the pipeline.
Furthermore, threads are arranged in the ring fasteners, the fasteners are bolts, and after the two semicircular cylinders are attached, the bolts penetrate through the ring fasteners on the two corresponding semicircular cylinders to be connected in a sealing mode.
Further, a sealing ring is arranged between the ring buckle and the bolt.
The utility model discloses a telescopic beneficial effect for heating power pipeline rush-repair lies in:
1) the utility model discloses a be provided with the joint strip of salient recess at the sleeve inner wall, joint strip contacts with the pipeline outside, and joint strip, sleeve inner wall and the outer wall of impaired pipeline form inclosed cavity, can prevent preliminarily that the hot water of pipeline seepage from flowing out from the gap and scalding the personnel of being under construction, also provide welding conditions for welding the joint between sleeve and the pipeline simultaneously;
2) the utility model has the advantages that the ring buckle arranged outside the sleeve is convenient for hoisting and dismounting, thereby avoiding personal safety such as scald caused by close installation of constructors;
3) the utility model discloses well sleeve preparation technology is simple relatively, the material principle is extensive, and the cost is lower relatively, can practice thrift a large amount of times when heating power is salvageed, in time resumes the resident and is heat commonly used.

Detailed Description
For better understanding of the purpose, structure and function of the present invention, the following description will be made in detail with reference to the accompanying drawings.
The sleeve in embodiment 1 can be according to concrete leakage pipe diameter size, prepares the not sleeve of equidimension, through the circular bottom surface of cutting sleeve, makes it agree with the leakage pipeline 2 outside, then combines sleeve and leakage pipeline welding through the electric welding, also welds the joint seam of two semi-circular section of thick bamboo 5 simultaneously, reaches sleeve and leakage pipeline complete sealing connection at last for the sleeve has fairly big pressure resistance to block that the hot water that leaks flows to the road surface and causes the road to cave in or the personal injury accident.
Pipeline and sleeve in the embodiment 1 generally adopt rigid material to make, and the sleeve suit has certain gap between sleeve and the pipeline outside the pipeline, and the personnel of being under construction are scalded easily from the gap outflow to the hot water seepage in the pipeline in the work progress, and joint strip 4 preferably adopts the elastic material of temperature resistant resistance to compression, and the leakproofness is good, effectively prevents hot water from flowing out from the gap of sleeve and pipeline.
