Abstract
The utility model belongs to a pipeline repairing instrument, particularly relates to an under- pressure quick repairing liquid- bag- type pipe clip. The utility model is composed of an upper pipe body (15), a lower pipe body (21), a face flange (19), a side face flange (13), a valve (9) and an overflow port (18), wherein, the inner side of the two ends of the upper pipe body (15) and the lower pipe body (21) is provided with a lug boss (18); the outer side of the lug boss (18) is provided with a polyethylene retainer ring (14), the outer side of which is provided with a liquid bag (4); the two ends of the liquid bag (4) are inserted together to form a ring; a liquid injection check valve (2) and an air- discharging check valve (3) are arranged fixedly at the upper part of the liquid bag (4). While the under- pressure quick repairing liquid- bag- type pipe clip is used, the operation can be carried out without stopping the operation of the equipment, closing the pipe valve, or emptying the medium in the pipeline, so as to avoid the medium waste and achieve quick repairing and good sealing performance, without disturbing the production and normal life. The utility model is applied to the maintenance of the water pipes, oil pipes or gas pipes.
Description
Technical field
The utility model belongs to the pipe-line reconditioning apparatus, and particularly a kind of band is pressed the quick service bladder type pipe.
Background technique
At present, during tap water conveyance conduit generation leakage failure, plumbous mouthful clamp, the high-early (strength) cement clamps of using more, the clamp of also useful blocking agent and other kind is repaired but all can not be with to press, must move by arrestment during repairing, the valve of blinding off a line, the medium of pipe interior must emptyings, and not only influence is produced and people's normal life, and the waste medium, be difficult to guarantee during construction that pipeline quality, time-consuming, effort, efficient are low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of valve, emptying interior media of need not blinding off a line when the maintenance pipeline leakage is provided, and band efficiently easy to maintenance is pressed the quick service bladder type pipe.
The technological scheme that the utility model technical solution problem adopts is: band presses the quick service bladder type pipe to be made up of upper tube body, lower tube body, face-flange, side flange, valve, flow-off, be characterized in being provided with boss in upper tube body and inboard, lower tube body two ends, the polyethylene back-up ring is equipped with in the boss outside, in the polyethylene back-up ring outside liquid capsule is housed, liquid capsule two ends are plugged on together, form an annular, be equipped with in the upper fixed of liquid capsule that liquid injects safety check and exhausting air returns only valve.
The beneficial effects of the utility model are: use band to press the quick service bladder type pipe, do not need the arrestment operation, the medium in valve and the emptying pipeline of need not blinding off a line, medium avoids waste, repair quick, good seal performance does not influence and produces and people's life, and this pipeline clamp is applicable to the pipeline maintenance of water, oil, gas medium.
