Description
Technical field
The present invention relates to the Hafu-type snap joint of the Hafu-type snap joint of pipeline, especially water supply pipe.
Background technology
It is known that be fed from water main conduit have cast iron pipe, pipe of cement, wherein ductile iron pipe is the longest sees, big portion
Subtube is all laid in underground, and these pipelines often occur breakage, fracture, seepage due to a variety of causes.Kazakhstan of the prior art
Husband's formula snap joint, is constituted a product by one group of rubber parts of two foundry goods and bolt, uses the Hough in Liang Geban garden during repairing
Formula snap joint, by the interior storehouse being included in pipeline leakage plugging device at piping failure, utilizes bolt to tighten up the rubber on Hough Ban Yuan composition surface
Sealing member is to sealing seepage.This method due to repairing employment is few, the set-up time is short, speed is fast, easy to use by from the beginning
The accreditation of water industry and vast general be used in pipe first-aid.
In order to ensure water safety, as carrying the water supply pipe wall of people's lives drinking water it is necessary to have isolate ferrum
The coating contacted with water, this coating meets sanitary standard.Accompanying drawing 1,2 is that in prior art, pipeline leakage plugging device uses state.Breathe out
Husband saves 2 outer walls having encased pipeline 1, controls and leaks into the water of pipeline outer wall and be deposited in pipeline leakage plugging device 2 inwall and pipeline 1 outer wall
In chamber.Because pipeline 1 outer wall is coarse and has certain error, deform after pipeline 1 breakage or fracture, so in pipeline leakage plugging device
Certain space must be left in chamber, and pipeline leakage plugging device two ends sealing ring 3 and both sides rubber weather strip 4 can only be allowed to rely on bolt 6 to tighten and seal
Live the frame loop-shaped that seepage, two ends sealing ring 3 in figure and both sides rubber weather strip 4 are integrative-structures.Although now completing pipe
Road repairing work, stricti jurise is said it only controls the water flowed to outside pipeline and no longer flows pipeline leakage plugging device.Now exist
Accumulation water 5 is left in pipeline leakage plugging device inner chamber.This accumulation water 5 cannot flow, actually in the case of having pressure inside pipeline 1
Become a chamber stagnant water, owing to pipeline 1 outer tube wall does not has health coating, pipeline leakage plugging device 2 inwall not to have health coating yet, stay in inner chamber
Accumulation water 5 Long Term Contact corrosion of metal and breed bacteria, if pipeline 1 is damaged elsewhere or maintenance stopping transportation and decompression, by
Connecting with pipe interior in damaged pipeline leakage plugging device inner chamber, the accumulation water 5 now stayed in pipeline leakage plugging device inner chamber can flow back to pipeline 1
Internal and polluted water.
Summary of the invention
It is an object of the invention to provide a kind of environmental protection pipeline leakage plugging device sealing shroud, reduce or even eliminate the inclusion cavity of pipeline leakage plugging device and stay
Deposit seeping phenomenon.
For achieving the above object, present invention employs techniques below scheme, a kind of environmental protection pipeline leakage plugging device sealing shroud, its feature
Being: sealing shroud includes two seal rubber sleeve halfbodies, seal rubber sleeve halfbody includes the semi arch sealing strip being positioned at two ends and is positioned at
The sealing edge strip of both sides, is the body of arc surface between semi arch sealing strip and sealing edge strip, semi arch sealing strip, sealing edge strip
And the body of arc surface is the conjoined structure of integral type, body, the intrados of semi arch sealing strip are kissed with pipe diameter to be covered
Closing, sealing shroud halfbody directly attaches with the outer tube wall being wrapped by pipeline and coordinates.
Above-mentioned sealing shroud is made up of two halfbodies, they respectively with two halfbodies of pipeline leakage plugging device with the use of going along with sb. to guard him and retraining
On the pipeline around breakage on pipeline, damaged part is blocked.Owing to body and the outer tube wall being wrapped by pipeline are direct
Attach and coordinate, when being embodied as, the implant in pipeline leakage plugging device body is pressed on the outer tube wall being wrapped by pipeline, the most directly
Connect and will block damaged part on pipeline, do not allow outside the water effuser in pipeline, now except charges, close in pipeline leakage plugging device inner chamber
Big envelope half is external no longer to be had and leaves the space accumulating water, if pipeline shutdown decompression the most do not accumulate breed bacteria water backflow and
Polluted water.
Accompanying drawing explanation
Fig. 1,2 it is the structural representation of prior art；
Fig. 3,4 it is the perspective view of the present invention；
Fig. 5,6 it is the use state reference map of the present invention.
Detailed description of the invention
In conjunction with Fig. 1,2, environmental protection pipeline leakage plugging device sealing shroud includes two seal rubber sleeve halfbodies 10, and seal rubber sleeve halfbody 10 includes
It is positioned at the semi arch sealing strip 11 at two ends and is positioned at the sealing edge strip 12 of both sides, between semi arch sealing strip 11 and sealing edge strip 12
For the body 13 of arc surface, semi arch sealing strip 11, body 13 directly attach with the outer tube wall being wrapped by pipeline and coordinate.
In conjunction with Fig. 5, the use state of 6, after assembling, body 13 directly attaches with the outer tube wall being wrapped by pipeline and coordinates, so
Just damaged part on pipeline directly being sealed, even if not sealed completely by the breach on tube wall, also be there is no concern that pipeline
The a small amount of rotten water body that there is a hydrops space outside and is formed, institute also would not have rotten water body to flow back to body in pipeline during decompression
Phenomenon, it is ensured that by the safety of water.
Preferably, the body 13 of described semi arch sealing strip 11, sealing edge strip 12 and arc surface is integral type
Conjoined structure, body 13, intrados and the pipe diameter to be covered of semi arch sealing strip 11 coincide, body 13 axial length direction
Dual-side flange shape laterally extends composition and seals edge strip 12, and sealing shroud halfbody 10 and the outer tube wall being wrapped by pipeline directly attach
Coordinate.Owing to have employed integral structure, it is ensured that sealing shroud be wrapped by the outer tube wall of pipeline directly against attached close
Close effect.
In conjunction with Fig. 3,4, described body 13 and the inwall of junction sealing edge strip 12 be smooth transition and with wrapped
Cover the concordant attaching of outer tube wall of pipeline, described body 13 and the smooth transition of inner surface in face, semi arch sealing strip 11 junction
And attaching concordant with the outer tube wall being wrapped by pipeline.Body 13 with seal edge strip 12, face, semi arch sealing strip 11 junction flat
Connect along transition, it is ensured that the damaged part on pipeline still ensures that the tube wall at new damaged part when having expansion
Outside does not haves hydrops chamber, the most thoroughly eliminates outside pipeline and has metamorphic water to flow back in pipeline.
