Description

Environmental protection pipeline leakage plugging device
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 of two semicircles 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 semicircle 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 1,2,3 is that in prior art, pipeline leakage plugging device uses state. Pipeline leakage plugging device 2 has encased the outer wall of 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 Chamber in.Because pipeline 1 outer wall is coarse and has certain error, deform after pipeline 1 breakage or fracture, so pipeline leakage plugging device Inner chamber must leave certain space, 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 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, reduce or even eliminate the inclusion cavity retention hydrops of pipeline leakage plugging device now As.
For achieving the above object, present invention employs techniques below scheme, a kind of environmental protection pipeline leakage plugging device, including two pipeline leakage plugging devices Half body unit, sealing shroud includes two sealing shroud halfbodies, and sealing shroud halfbody includes the semi arch sealing strip being positioned at two ends and is positioned at Being the body of arc surface between the sealing edge strip of both sides and semi arch sealing strip and sealing edge strip, described body is for expanding rubber Glue, after body water-swellable, outer wall is against on the inwall to pipeline leakage plugging device half body unit, and the inwall of body is coated on pipeline outer wall.
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, body is expanded rubber, and after body water-swellable, outer wall is against to pipeline leakage plugging device half On the inwall of body unit, the inwall of body is coated on pipeline 1 outer wall, is blocked by damaged part.Owing to filling up after set volume expansion Pipeline leakage plugging device and the cavity being wrapped by between pipeline, when being embodied as, do not allow outside the water effuser in pipeline, now in pipeline leakage plugging device The space accumulating water is no longer had except sealing shroud half is external, if pipeline shutdown decompression does not the most accumulate the water of breed bacteria in chamber Reflux and polluted water.
Accompanying drawing explanation
Fig. 1,2,3 are the structural representations of prior art;
Fig. 4,5 it is present configuration schematic diagram.
Detailed description of the invention
See Fig. 3,4, a kind of environmental protection pipeline leakage plugging device, including two pipeline leakage plugging device half body units 20, sealing shroud includes two sealings Set halfbody 10, sealing shroud halfbody 10 includes the semi arch sealing strip 11 being positioned at two ends and the sealing edge strip 12 being positioned at both sides and half Being the body 13 of arc surface between circular arc sealing strip 11 and sealing edge strip 12, described body 13 is expanded rubber, and body 13 is met Water expand after outer wall against on the inwall to pipeline leakage plugging device half body unit 20, the inwall of body 13 is coated on pipeline 1 outer wall.
Preferably, described semi arch sealing strip 11, seal edge strip 12, the body 13 of arc surface is integral type Conjoined structure and all use expanded rubber.
Preferably, the described inwall that body 13 wall thickness is pipeline leakage plugging device half body unit 20 and pipeline 1 outer wall spacing 1/2~1/6.
The scheme being more highly preferred to, between the described inwall that body 13 wall thickness is pipeline leakage plugging device half body unit 20 and pipeline 1 outer wall Away from 1/3~1/4.
Fig. 4 is that two pipeline leakage plugging device half body units 20 and two sealing shroud halfbodies 10 are arranged on original state on pipeline 1, figure Middle displaying is 1/3 footpath, chamber that body 13 wall thickness is perimetrical lumen in sealing shroud halfbody 10, expands and fill up cavity after meeting water, as Shown in Fig. 4.Expanded rubber is exactly with natural rubber and water-absorbing resin, such as sodium polyacrylate, for primary raw material, and with reinforcing agent, Reinforcing agent is that additive is mixed to prepare hydro-expansive rubber, and hydro-expansive rubber has nontoxic, tasteless, pressure advantage, permissible Drinking water pipeline uses.Accompanying drawing 3,4,5 show socket fitting type structure, somewhat more complex compared with Fig. 1, the straight tube structure shown in 2, The present invention is equally applicable.
