Description

Pipeline urgent repair device

Technical field

The utility model relates to the device of the pipe first-aid that leaks, refer in particular to a kind of when being applied to mesolow pipeline localized seepage pipeline do not quit work or the situation of the very short time of stopping work under rush to repair pipeline, the seal leak point makes the pipeline urgent repair device of pipeline proper functioning.

Background technique

When present mesolow pipeline such as water supply pipe localized seepage, the repairing of can only cutting off the water, the general replacing pipeline way that adopts is rushed to repair, need so ducted water have been put for a long time, sometimes because of the valve corrosion or damage and to close total valve and could rush to repair, causing more, the large size user cuts off the water, the big more then discharge time of the area of cutting off the water is long more, the water of the long more then waste of discharge time is many more, after the pipeline repair and replacement were intact, the slime water in the pipeline also can cause certain waste, meets the Very Important Person that can not cut off the water, then to make a plan cut off the water after repairing again, the water of waste is just more.After ducted water has been put, take off damaged pipeline again, change two joint short tube and sleeves then, with expanding cement or plumbous urgent, time-consuming inconvenience is if adopt expanding cement again, then the same day, pipeline can not use, can use after must waiting expanding cement to do the jail, rush to repair the minimum needs of pipeline 24 hours of the medium specification in a place like this, long reaches 2-3 days.

Summary of the invention

The purpose of this utility model is improved and is innovated at the shortcoming that exists in the background technique and problem, provides a kind of simple in structure, convenient and practical, the pipeline urgent repair device that cost is low.

Technical solutions of the utility model are a kind of pipeline urgent repair devices that are located on the pipeline that leaks of structure, comprise shell and Sealing, wherein:

Shell is two monolithic cases that semicircular shell combines by the band tightening eave, and the shell two ends are the sealed end that is provided with to the Sealing standing groove of outer lug, and the middle part is a closed chamber;

Sealing comprises the semicircle Sealing that is arranged in the Sealing standing groove, and be located in bar shaped Sealing between the upper and lower tightening eave, and two groups of semicircle Sealings and bar shaped Sealing are relatively set into a complete annular seal body, and wherein semicircle Sealing inboard is made as serrated face and is close to piping erection;

Described shell and Sealing are spliced by separable two-part, and two-part are by the leakage section of fastening piece lock ring in the pipeline outside.

Advantage of the present utility model and beneficial effect:

The utility model maintenance pipeline is convenient, and little seepage does not need to cut off the water, and bigger leaking only need just can be rushed to repair the reduction of the pressure in the pipeline, promptly do not influence production and do not influence life again.And easy to maintenance, the repairing of DN400 water supply line only needs two pipeline urgent repair devices being combined in leakage, tightens with bolt get final product again, and the pipeline of rushing to repair the medium specification in a place is general only need just can to complete in 4 hours.The utility model is cost saving also, need change one with the pipeline of a traditional same specification of method repairing and save 6 meters long pipelines, and the excavation working pit is not only long but also big, and road of city is destroyed greatly, and it is big to change the pipeline workload, and the excavation workload is also big.And the not enough conventional method fittings cost of the pipeline urgent repair device price of a same specification 1/3rd.
