Description
Technical field
The utility model relates to a kind of special purpose parts that keeps in repair supply pipe, and the special-purpose rapid pipe joint especially for the repairing PE feedwater piping of not cutting off the water supply belongs to the plumbing technical field.
Background technique
In recent years, PE tubing development rapidly, application quantity increases year by year, Comparatively speaking really relatively lags behind with supporting construction, the equipment of maintenance aspect, the experience of PE pipeline, then more lags behind aspect the quick damage repair technology of PE feedwater piping.Along with of the extensive use of PE tubing in the feedwater field, this problem day by day shows especially, in laying or Construction and Maintenance process, causes piping failure as pipeline for various reasons, even tubing dug disconnected phenomenon, is badly in need of a kind of assembly of not cutting off the water supply and just can rush to repair fast this moment.Because the toughness of PE material is better, its mode of failure mostly is local hole, the method and the rapid pipe joint of some repairings at present, all be not suitable for PE tubing, its reason is that the PE pipeline mainly connects, repairs by electric smelting or hot melt, but when water supply line breaks down suddenly, even throttle down, in pipeline, also be difficult to thoroughly water be stopped breaking, heat, electric smelting welding all need be carried out under very dry condition, so can not adopt the way repairing of heat, electric smelting, can only adopt the method for mechanical coupling, and the mechanical coupling key is the sealing problem of the tubing that will solve.Because the material characteristic of PE pipe, under the effect of different pressures inside and outside the tube wall, its long-term creep performance can cause the sealing part diameter to diminish or axial shrinkage causes and leaks, and the out of roundness of tubing also is the main cause that the PE pipe is different from PVC-U pipe damage repair technology in addition.Based on above-mentioned factor, demand providing a kind of structural member that can under the condition of not cutting off the water supply, solve the repairing of PE supply pipe fast urgently.
Summary of the invention
The utility model is used to overcome the defective of prior art and provides a kind of PE of avoiding pipeline because of distortion is leaked, reliable sealing PE supply pipe is not cut off the water supply repairing rapid pipe joint.
The alleged problem of the utility model is that following technological scheme solves:
The repairing rapid pipe joint of not cutting off the water supply of a kind of PE supply pipe, comprising in the formation can be by bolt sealed two halves round bush and the seal ring that is arranged in the sleeve, its specialization is: described semicircle sleeve 1 inwall two end part are provided with pawl 5, and pawl tilts to semicircle sleeve ends direction.
The repairing rapid pipe joint of not cutting off the water supply of above-mentioned PE supply pipe, described seal ring is made up of 2 butt joints of two halves seal ring, its interface is along pipeline axial, the semitight circle is similar to the frame shape, it is made of with the axial seal bar 2-2 that is connected two radial seal semi-rings the radial seal semi-ring 2-1 that is positioned at two end part, and the inwall of radial seal semi-ring is provided with Contact Tooth 2-4.
The repairing rapid pipe joint of not cutting off the water supply of above-mentioned PE supply pipe, described semicircle sleeve middle part is provided with ring-type tubing docking groove 3, and its groove width, groove depth are advisable to contain tubing hot melt butt joint, and ring-type tubing docking groove is provided with radial direction through hole 9, and the hole is provided with plug 6.
The repairing rapid pipe joint of not cutting off the water supply of above-mentioned PE supply pipe, described semicircle sleeve lining are provided with the restraining groove 7 with semitight circle profile phase coupling.
The repairing rapid pipe joint of not cutting off the water supply of above-mentioned PE supply pipe, described axial seal bar middle part is provided with and the corresponding male part 2-3 of ring-type tubing docking groove.
The utility model is the rapid pipe joint that a kind of PE of being mainly used in pipeline is not cut off the water supply and rushed to repair, it designs according to the material characteristics and the deformation rule of PE tubing, its main feature is as follows: 1. overall structure is to be made up of two sealed hollow semicircle sleeves of bolt, and fitting operation is very convenient; 2. the pawl of semicircle sleeve lining end setting not only can play the purpose to PE tubing Hui Yuan, still can effectively prevent to cause the problem of destroying sealability that moves axially because of tubing stretches; 3. the special construction of seal ring can make axial seal and radial seal solve simultaneously, and easy for installation, and sealing is reliable.Show that through on probation the utility model is simple in structure, easy to connect, operation is rapid, sealing is reliable, repairs same suitable for the breakage of pvc pipe material.
