Abstract
The utility model relates to a pipeline leakage stopping device, in particular to a pipeline leakage stopper with a decompressed drainage device, which is used for stopping the leakage of pipelines with pressure flowing liquid. The pipeline leakage stopper comprises a leakage stopping hoop body with the decompressed drainage device and a lower hoop. The body is a circular-arc plate with two folding edges, and bolt holes are arranged on the folding edges of the circular-arc plate, four reinforcing rib plates are arranged on the body, and the decompressed drainage device is fixed on a drainage hole on an outer ring of the body by welding. An inner ring of the body is provided with a sealing ring fixing collar in which a sealing ring is placed. The lower hoop is a circular-arc plate with two folding edges, and bolt holes are arranged on the folding edges of the circular-arc plate.
Description
Technical field
The utility model relates to a kind of device of pipe plugging, and particularly a kind of pipeline to band pressure working fluid carries out the pipe plugging device of the band pressure release drainage system of leak stopping.
Background technique
At present, after pipeline leaks, or change pipeline, or the leak of pipeline is taked leak stopping.Yet no matter be to change pipeline or leak stopping, the pressure that all needs to close in the pipeline could be constructed.When closing pressure not, when directly the pipeline that leaks being carried out leak stopping, the working fluid that has pressure releases from the leak of pipeline, will influence the carrying out of leak stopping work, also has influence on plugging effect.In addition, this pass presses the drawback of leak stopping a lot, and is long as the leak stopping consumed time, needs to close the also corresponding prolongation of time of pressing, and after pressing for the pipeline pass that can not close pressure aborning, can cause damage to production.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and provide a kind of pipeline to band pressure working fluid to carry out the leak stopping device of the band release drainage system of leak stopping.
The technical solution of the utility model is: a kind of pipe plugging device with the pressure release drainage system, it comprises leak stopping anchor ear body and a following anchor ear of a band pressure release drainage system.Body is the circular arc plate of one two sideband flanging, and the flanging of circular arc plate is provided with bolt hole.Body is provided with four and strengthens gusset, and the pressure release drainage system is fixed by welding on the conduction hole of body outer ring.At the inner ring of body, be provided with a seal ring retaining ring, seal ring just is placed in the seal ring retaining ring.Following anchor ear is the circular arc plate of one two sideband flanging, and the flanging of circular arc plate is provided with bolt hole.
The leak stopping device adopts dredges stifled again thinking earlier, draws away and reduces earial drainage pressure leaking water by the pressure release drainage system on the leak stopping device, alleviates difficulty of construction, convenient working.During leak stopping, leak stopping anchor ear body and following anchor ear are fixed on the leak of pipeline by being threaded, rely on the seal ring on the leak stopping anchor ear body to seal around the leak of pipeline, close the valve of pressure release drainage system then, realize preliminary leak stopping.After realizing preliminary leak stopping, reach final leak stopping purpose thereby in time leak stopping anchor ear body and pipeline welding are connected as a single entity again.When leak stopping anchor ear body and pipeline welding,, and then be welded on the pipeline with the border seal of sealing plate with leak stopping anchor ear body.
During welding combustible fluid pipeline, clean out the inflammable substance of pipe surface, manifold pressure and barometric pressure are in a ratio of malleation.
The utility model compared with prior art has following characteristics:
1, according to dredging stifled again pipe plugging basic ideas earlier, on leak stopping anchor ear body, designed the release drainage system.Draw away and reduce earial drainage pressure leaking water by the pressure release drainage system, alleviate difficulty of construction, convenient working.
2, can design and produce special leak stopping anchor ear according to on-site actual situations, select suitable moulding sealing material for use according to the chemical property of leaking medium, pressure, temperature etc. in addition, structure, principle are quite simple, flexible, carry out complicated theoretical calculation and tight technological operation and need not form the seal ring problem with regard to the scene temporarily.
3, adopt annular seal, seal and stressedly evenly do not exist stress concentrated, can effectively improve voltage withstand class.
4, except that on straight length, using, also can carry out leak stopping, only need to make corresponding special-shaped seal seat and closure gasket groove according to on-the-spot size situation to privileged sites such as elbow, undergauge, threeways.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
