Abstract
The utility model relates to a device for repairing damaged pipe lines, comprising a lining, a flat support and a locking mechanism. When the utility model is used, the damaged part of a pipe line is cut off, then the pipe line is inserted in the opening of the flat support, the lining is arranged in the port of the pipe line, and the flange of the flat support is tightly locked by the locking mechanism. The device for repairing damaged pipe lines has the advantages of simple structure, low requirement on environment when working, convenient and quick repair of a pipe line, and avoidance of water leakage caused by the deformation of the pipe line due to the creep deformation of P E and P Pmaterials, and solves the problem that the pipe line made of P E and PP materials can not be connected mechanically due to creep deformation.
Description
Technical field
The utility model belongs to pipe rehabilitation technology, particularly relates to a kind of pipeline rehabilitation device.
Technical background
Be used for draining, pipelines such as protection cable etc. use of a specified duration can be aging and part occurs and damage phenomenon; electric smelting saddle type is repaired, connection, the quick interconnection technique of flange etc. are overlapped in electric smelting and present restorative procedure has; these technology all are to utilize the good welds of PE material, adopt the form of homogeneity sweat soldering to repair.The welding interface that this kind mode requires must be clean.What but the cracking of normal conditions water supply water pipe or seepage required is quick repairing, is difficult to could weld behind the pipeline bone dry by the time.Need special-purpose welding equipment during construction, therefore must draw when construction and establish electric wiring, and need certain installing space when mounted, these generally are difficult to be met in actual repairing process.
Mainly contain two kinds of first-aid repair machines now at the PVC repairing, a kind of is flanged quick repairing joint, and another is the repairing joint of Hough formula, flanged repairing joint manufacture cost height, and need axially tight a bolt during owing to installation, so mounting hardness is also bigger; The first-aid repair machine of Hough formula, simple structure, it is also convenient to install, but the sealing reliability of Hough rubber ring is lower, occurs seepage easily, and generally be the pipeline rehabilitation device of Φ below 300.
Chinese patent application number is that 200320101191.8 utility model patent discloses a kind of water supply line straight tube leakage repairing device, consist predominantly of first circular buckle and lower semi-circular buckle, offer the upper and lower seal groove of sealing respectively in the edge of upper and lower semicircle buckle, and be inlaid with upper and lower seal ring respectively; Be provided with the bolt hole at the axial edge position of upper and lower semicircle buckle and cross-under has clamping bolt; Offer the dewatering orifice and be provided with seal plug in the center portion of first circular buckle or lower semi-circular buckle.Repair the effect that water pipe decreases leakage though this utility model patent can play to a certain extent, this patented technology can not effectively prevent the pipe deforming that PE, PP material creep cause and produce problems such as leaking, can't use mechanical connection.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of novel rapid pipeline obturator is provided.
The technical solution adopted in the utility model is:
A kind of pipeline rehabilitation device that is used to repair damaged pipe, comprise at least two flat hold, two linings and a locking framework, described lining lays respectively in two ports of pipeline to be repaired, described flat holding then is nested with on the outer surface of pipe ends mouth to be repaired, and described locking framework is fastenedly connected between two flat holding.
In order to make the sealability after the pipeline rehabilitation more outstanding, the utility model is with seal ring on the flat flange that holds, and the flat socket that holds also is equipped with seal ring, and also is provided with baffle plate between two flat holding.
Described locking framework will be put down and be held flange, seal ring and baffle plate locking.
Lining of the present utility model adopts corrosion-resistant and robust material is made, and preferably adopts steel to mould lining.In order to strengthen being connected of lining and pipeline, stainless stirrup can also be set where necessary on lining as auxiliary lining.
During the utility model work, at first that the pipe section that damages is sawed-off, two end mills are flat.The flat socket that holds is loaded onto seal ring, pipeline is inserted the flat bellmouth that holds again; Put a steel respectively in the port of pipeline then and mould lining, can add that in case of necessity stainless stirrup makees auxiliary lining, on the flat flange that holds, also put seal ring; To put down at last and hold flange, baffle plate is connected and fixed with bolt.
Quick obturator of the present utility model has following advantage:
1, the utility model can be directly used in the connection that butterfly valve, the pipeline breaking of flange place are installed;
2, the utility model effectively prevents from the pipe deforming that PE, PP material creep cause and produces to leak by steel being moulded the port that lining is put into pipeline to be repaired, has solved PE, PP pipeline can't use mechanical connection because of the creep problem problem;
3, the utility model is less demanding to the drying property and the spatter property of pipeline when work, can just can repairing be installed at once when cutting off the water soon or having less water pressure, helps the fast quick-recovery normal water supply of pipeline;
4, the utility model does not need too big excavation works when work, helps saving the repairing time and saves the repairing expense;
5, the equipment of the utility model use is simple, need not power by electric wiring;
6, the utility model is by placing seal ring on flat bellmouth that holds and flange, makes sealing and repairing reliability height.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a flat bearing structure schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structural representation of the present utility model as shown in Figure 1, by steel mould lining 2, flat hold 3, bolt 4 and nut 5, baffle plate 6, seal ring 7 form, present embodiment is sawed-off with the impaired part of pipeline 1 to be repaired, mills the port at flat two ends; Adopt identical flat of two specifications to hold 3, each is flat holds 3 socket and loads onto seal ring 7, and a port with pipeline 1 to be repaired inserts flat 3 the bellmouth that holds then; Respectively put a steel in two ports of pipeline 1 to be repaired and mould lining 2, also put seal ring 7 each flat holding on 3 the flange then; At last with two ports alignment of pipeline 1 to be repaired, in the middle of holding 3, port flat place a baffle plate 6, with bolt 4 and nut 5 two flat flanges of 2 of holding are locked together with the baffle plate 6 of centre again.
Flat bearing structure schematic representation of the present utility model by placing seal ring 7 flat holding on 3 bellmouth and the flange, makes sealing and repairing reliability height as shown in Figure 2.
The utility model is moulded steel the port that lining 2 is put into pipeline 1 to be repaired again, effectively prevent from the pipe deforming that PE, PP material creep cause and produce to leak, and has solved PE, PP pipeline can't use mechanical connection because of the creep problem problem;
The equipment that the utility model uses is simple, need not power by electric wiring, less demanding to the drying property and the spatter property of pipeline when work, can when cutting off the water soon or having less water pressure, just can repairing be installed at once, help the fast quick-recovery normal water supply of pipeline; Do not need too big excavation works in addition, help saving the repairing time and save the repairing expense.
