Abstract
The present invention relates to a kind of PE seamless linear-mounted repairing pipe, it is characterized by that when said repairing pipe is extruded, it is circular, after it is folded along axial direction, its section is made into C-type form so as to reduce cross-section area of repairing pipe, so that the repairing pipe can be easily inserted into the pipe to be repaired. After said PE seamless linear-mounted repairing pipe is inserted into the pipe to be repaired, it utilizes the features of PE material which has memory, and adopts the process of injecting steam to heat and make it be restored into the initial circular section state, and lined in the pipe to repaired, then high-pressure air is injected to cool and make it be tightly closed to inner wall of repaired pipe so as to attain the goal of repairing repaired pipe.
Description
The present invention relates to a kind of PE and repair pipe, particularly a kind of PE seamless lining repairing pipe.
Have known pipeline rehabilitation now, the old pipelines of on-the-spot excavation that adopt be welded into new pipe, or interspersed new pipe are repaired more.Easily cause poor, the easy to leak of firm welding degree in operation, defectives such as pipeline flow minimizing.
The objective of the invention is to propose a kind of PE seamless lining repairing pipe that is repaired inner tube wall of being close to.
Task of the present invention is finished like this: PE seamless lining repairing pipe is rounded when extruding, and cross section, folding vertically back becomes C type shape, has reduced to repair the cross-section area of pipe, makes to repair to manage to insert easily to be repaired in the pipe.After PE seamless lining repairing pipe inserts and is repaired pipe, utilize the PE material to have the characteristics of memory, employing pours into water vapor heating makes it revert to initial circular cross-section state, is lining in to be repaired in the pipe, it is close to be repaired inner tube wall by pouring into the high-pressure air cooling then; Or adopt and directly to pour into the empty vapour of pressure and make it revert to initial circular cross-section state to be close to and to be repaired in the pipe, repair the purpose that is repaired pipe thereby reach.For keeping the C type sectional shape of PE seamless lining repairing pipe, can the adhesive tape stickup fix before the plug-in mounting, after insertion is repaired pipe, make the bandage fracture through adding compression swelling.
The present invention constructs convenient, and pipeline rehabilitation quality and working life can reach again the level of pipe laying, is specially adapted to the reparation of pipeline that can't slot grooving.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is the axially folding sectional view of PE seamless lining repairing pipe of the present invention.
Fig. 2 is a PE seamless lining repairing pipe erection drawing of the present invention.
According to Fig. 1, Fig. 2, PE seamless lining repairing pipe is rounded when extruding, and is folded into C type sectional shape (1) vertically before the lining dress, and to reduce cross-section area, insertion is repaired in pipe (2) road easily.After PE seamless lining repairing pipe inserts and to be repaired pipe (2), adopt the sealing of pipe tail, pour into the water vapor heating and make it revert to initial circular cross-section state (3), cool off and it is close to be repaired pipe (2) inwall by pouring into high-pressure air then; Or adopt the sealing of pipe tail, directly pour into the empty vapour of pressure and make it revert to initial circular cross-section state (3) to be close to and to be repaired in the pipe (2), thereby reach the purpose that reparation is repaired pipe (2).Be the C type sectional shape (1) of maintenance PE seamless lining repairing pipe, can adhesive tape (4) stickup fix before the lining dress, after insertion is repaired pipe (2), make adhesive tape (4) fracture through adding compression swelling.
Claims (4)
1, a kind of PE seamless lining repairing pipe, it is characterized in that not serving as a contrast the dress before can be folded into C type sectional shape (1) vertically.
2, PE seamless lining repairing pipe according to claim 1, it is characterized in that inserting be repaired pipe (2) after, the water steam heating makes it recover initial circular cross-section state (3), cools off by high-pressure air then it to be close to be repaired pipe (2) inwall.
3, PE seamless lining repairing pipe according to claim 1, it is characterized in that inserting be repaired pipe (2) after, the also available pressure sky vapour that directly pours into makes it revert to initial circular cross-section state (3) and is close to and is repaired in the pipe (2).
4, according to claim 2 or 3 described PE seamless lining repairing pipes, it is characterized in that can pasting fixation of C type sectional shape (1) by adhesive tape (4) before the lining dress, after insertion is repaired pipe (2), make adhesive tape (4) fracture through adding compression swelling.
