Description

A kind of tapered pipeline leakage-baffling device

Technical field

The utility model relates to a kind of tapered pipeline leakage-baffling device that adapts to different tube diameters, belongs to engineering machinery field.

Technical background

Not carrying out instantaneous leaking-stopping pipe pressurized not stopping under the disconnected situation, is ubiquitous problem in the pipe-line system.Whether can under the situation that does not influence commercial production and social life, successfully realize leak stopping effectively and quickly, many scholars attempt adopting different modes to solve this problem with R&D institution.

In the busy day by day process of construction in city; Unavoidably there is the pipe leakage phenomenon. its main cause has two kinds; A kind of is the aging leakage that causes because pipeline gets rusty; A kind of in addition is the leakage that sporadic destruction is caused pipeline. the running in city need be kept through these pipelines, therefore cannot arbitrarily close pipeline, stops to carry the liquefied gas material.Under the situation of therefore not closing to pipeline, how pipe leakage is repaired, i.e. leak stopping in time; Since be the focus of the previous research of order. be leak stopping, so just requiring can be in the short period of time, if deal with problems. and the time of leak stopping is long more; The material that then leaks is also just many more; This unavoidably causes the pollution of waste or environment. and this just requires leakage-baffling device to be convenient to operation, and is swift to operate, and cost will meet the requirements of the customers.

Summary of the invention

In order to realize the leak stopping of pipeline quick pressurize, the utility model provides a kind of simple in structure, low cost of manufacture, easy to operate, the tapered pipeline pressure sealing device that is easy to promote.Use this device, only rely on an operator, at short notice just can be fast with the manual leak stopping of pipeline leak.

For realizing above-mentioned purpose, the utility model is realized through following technological scheme: leakage-baffling device is made up of card locking device, deflation band and diaphragm seal respectively.Be rectangular sheet after diaphragm seal launches, process, occupy the leakage-baffling device internal layer behind the coiling by macromolecular elastomer class material, be close to the broken pipe outer wall after, can reach the purpose of shutoff; Be rectangular sheet after tightening the band expansion, can reel, occupy the skin of diaphragm seal, can apply external force, guarantee combining closely of diaphragm seal and pipeline diaphragm seal; Card locking device with tighten the band two ends and link to each other, form cyclic structure, tighten up or loosen tensioning means, tighten to be with and also tighten up thereupon or loosen.

Described diaphragm seal, its two ends have the oblique angle that agrees with of correspondence each other, back of reeling, so avoid the broken pipe caliber not simultaneously sealing piece occur overlapping, turn up phenomenon and take place, guaranteed the leakproofness of shutoff.

Described deflation band; One end is the single hole end, is provided with single circular hole, is fixed on the rivet of handle set of card locking device; The other end is the porous end; Be provided with a plurality of circular holes, wherein each circular hole is inserted on the bolt of the clamping hook seat raising in the tensioning means after all can tightening up according to the size of leak stopping pipe diameter.

Described card locking device is made up of the bolt of handle, handle bearing pin, handle set, rivet, handle set bolt, U-shaped degree of tightness pull bar, adjusting nut, deck and hook seat raising.Wherein the handle bearing pin is cylindric, and its two ends are provided with circular opening, and the screwed pull bar of the U-shaped opening end of U-shaped degree of tightness pull bar is fixed on the circular opening, and the handle bearing pin runs through handle, and handle, U-shaped degree of tightness pull bar are linked together; Rivet links together handle set, handle, plays the point action of handle simultaneously; Handle set is spill, and its bottom inner face central point is provided with handle set seat tapped hole, can the single hole end of the single circular hole that connects thing be fixed on it through screw; It is block that deck is, and which is provided with protruding bolt, and the other end that is provided with a plurality of circular holes is fixed on it; One side of deck also is provided with Baltimore groove; The deck bottom is circular-arc, and is evenly distributed with detent projection, and circular-arc bottom directly contacts with diaphragm seal; This convexity can locally embed the diaphragm seal surface, increases the frictional force between deck and the diaphragm seal; Handle set, its bottom is circular-arc, and is evenly distributed with detent projection, and circular-arc bottom directly contacts with sealing piece.This convexity can locally embed the diaphragm seal surface, increases the frictional force between handle set and the sealing piece.Tighten

The band of the utility model design is pressed the instantaneous leaking-stopping device, can be adapted to the pipeline instantaneous leaking-stopping of different tube diameters, and is simple in structure, easy to use.Set sealing piece, its two ends are provided with the oblique angle that mutual correspondence is agreed with, and then avoid the broken pipe caliber not simultaneously diaphragm seal occur overlapping, turn up phenomenon and take place, guaranteed the leakproofness of shutoff and the adaptability of different tube diameters.
