Description
Technical field
The utility model relates to repairing pipe technical field, in particular to a kind of pipe decompression patcher.
Background technique
Under particular surroundings or working condition, in the case that repairing pipe can not cut off the water supply or reduce hydraulic pressure, pipeline pressure
When larger, dressing type repairing, then gradually tighten outer screw when, patcher internal pressure is gradually increased, and is easily led in patcher
Portion's edge seal glue is deviate from by high pressure water flow strikes, can not be successfully repairing.
In existing pipeline patching device structure, it is equipped with relief hole usually on its patcher shell and is fitted with relief hole inserting
Match silently, when implementing repairing work, need to first unload silently, patcher upper-lower casing is mounted at damaged pipeline, with tight
Firmware compresses pipeline patching device upper-lower casing；The pressure in pipeline can be let out by the relief hole on patcher during the installation process
Pressure, in order to Fast Installation, will silently block relief hole, and complete entire repairing pipe process after being installed.
Although working as however, said modules structure and its operating process can satisfy basic repairing pipe operation needs
, can be very difficult by the operation being silently installed in relief hole when the internal pipe pressure being repaired is excessive, or even existing can not
The case where installation, brings inconvenience to the normal use of pipeline patching device.
Therefore, the closure of relief hole how is realized, simple and effective to improve operating efficiency and the reduction of pipeline patching device
Its operation difficulty is the important technological problems that those skilled in the art need to solve at present.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of pipe decompression patcher, are not cutting
In the case where disconnected high-pressure water or reduction hydraulic pressure, patcher internal pressure is reduced, prevents patcher internal edge sealant by height
It presses water impact and deviates from.
The technical solution of the utility model are as follows: a kind of pipe decompression patcher, including shell, straight coupling and sealing element,
There is relief hole, one end of straight coupling is connected to by relief hole with housing cavity, and the other end passes through sealing element on the shell
Sealing.
Further, the sealing element is plug or valve.
Further, the straight coupling has external screw thread, and the plug or valve have internal screw thread.
Further, the shell includes upper housing and lower case, and upper housing is connected with lower case by assembly parts, relief hole
The middle part of upper housing is set to straight coupling.
Further, the assembly parts include multiple front bands, multiple lower catch hoops, screw bolt and nut, multiple front band difference
Set on the two sides of upper housing, multiple lower catch hoops are respectively arranged on the two sides of lower case, and front band and lower catch hoop are respectively equipped with threaded hole,
Bolt passes through threaded hole and connect with nut, and upper housing is connected by way of assembly with lower case, even if having oil, water in pipe, because
It need not weld and also be not required to heat, and without fire, without explosion danger is applicable in and is installed on various leakage pipes.
Further, the diameter of the relief hole and straight coupling is 15-50mm.
Further, the distance between outer wall of the inner wall of the shell and leakage pipe is 1.5-3mm, when pipe leakage pressure
When power is smaller, the leakage fluid of leakage pipe can be temporarily accommodated, the installation of shell is facilitated.
Further, the axial ends of the shell is respectively equipped with seal gasket, and the outer wall of seal gasket and leakage pipe supports
It connects, the joining place of seal casinghousing and leakage pipe.
Further, the straight coupling is single-ended screw thread, and the non-threaded end of straight coupling is welded in housing central section.
Further, the straight coupling and shell are mold integrally casting shaping, and integral strength is big, good seal performance.
The working principle of above-mentioned pipe decompression patcher,
1), when pipe leakage point pressure is little, sealing element uses plug, and when installation first removes plug, can not stop
In the case where pressing, being changed without pipeline, leak repairing directly is carried out to leakage point using patcher, after mounting the housing to leakage pipe,
Again by plug seal feed-through connector；
2), when pipeline leakage point pressure is excessive, sealing element uses valve, first opens valve to normally open, then by shell
Body is installed to leakage pipe, and pipe leakage point can make shell smoothly complete peace by straight coupling to valve drainage pressure
Dress, directly closes valve after being installed, if after closing valve, shell and pipeline joining place still have leakage, can lead to
Opening valve pressure release is crossed, adjustment shell is reinstalled, convenient for operating repeatedly, while saving certain manpower and processing time.
The utility model compared with the existing technology, has the advantages that
The pipe decompression patcher of the utility model, can be in the case where not stopping to press, be changed without pipeline, to aging, rust
Situations such as losing the pipeline sand holes made, fracture progress Rapid-Repair, easy for installation, construction efficiency is high, can apply without special tool(s)
Work operation, it is especially prominent under conditions of construction environment is more severe.
The pipe decompression patcher of the utility model, in the case where not cutoff high water source or reduction hydraulic pressure, reduction is repaired
Device internal pressure is mended, prevents patcher internal edge sealant from being deviate from by high pressure water flow strikes, repairing personnel is reduced and is repairing
When to sealant return dress, adjustment, save repairing the time, smoothly complete repairing pipe.
The pipe decompression patcher of the utility model, assembly and disassembly are mutually constructed without flanged complete cycle, only twist spiral shell from a side chain
Bolt, thus pipeline arrangement and construction space can be saved up to 50%, when repairing pipeline, even if there is oily, water state in pipe, because need not
Welding is also not required to heat, and without fire, without explosion danger is repaired using wrapping mode, can be in manpower, material resources and financial resources
It is upper to obtain best Economic model.
