Description
Technical field
The present invention relates to pipe first-aid equipment technical fields, especially for leakage or in broken pipe repaired
Lining formula pipeline patching device.
Background technique
Pipeline is modern society's " blood vessels system ", is responsible for important social function, such as water supply, gas supply, fuel feeding, blowdown
Damaged or leakage often occurs Deng, these pipelines.Relatively the repairing mode of mainstream is first to be excavated at present, then uses pairing
Formula patcher is connected on the outside of broken pipe and is repaired.
Opposite patcher is very convenient, but also has its limitation, the degree of roughness and pipeline to pipeline external surface
Circularity has very big requirement, such as: bigbore Prestressed concrete cylinder pipe, and the pipeline in many cities is located at major trunk roads
In the following, these pipelines Yi Dan damage once must road pavement excavated, normal traffic certainly will be will affect.
Interior packing method technique is to be pressed to stainless steel packing, using professional hydraulic device by special high-intensity sealing sealing
Band (material is ethylene propylene diene rubber) is fixed on pipeline joint-seam or leakage position two sides, repairs, makes to pipe joint
The extensive recovery design bearing capacity of pipeline is not limited by apart from conditions such as length, pipeline reducing diameter, pipe joint form, buried depth of pipeline
System.
As disclosed in the application for a patent for invention that publication No. is 105822867 A of CN " a kind of internal expansion type rubber seal and its
Using ", internal expansion type rubber seal includes rubber seal zone circle and internal expanding steel ring, and rubber seal zone circle is applied to pipeline socket
The gap location formed after insertion pipeline birdsmouth, internal expanding steel ring are close to rubber seal zone circle inner wall, form internal expansion type structure.Specifically
Ground, the quantity of internal expanding steel ring are two, the middle part of rubber seal zone circle trend shape after pipeline socket insertion pipeline birdsmouth
At gap, the inner wall at both ends and two internal expanding steel rings form internal expansion type structures, and form two seals band in gap two sides, interior
Steel ring both ends of rising are provided with clamping opening, are caught in elastic slice between clamping opening, prop up internal expanding steel ring using elastic slice.
This internal expansion type rubber seal has the following disadvantages:
First, since two internal expanding steel rings are mutually indepedent, when being repaired to pipeline, it is necessary to respectively in two
The steel ring that rises is operated, and two procedures are excessively cumbersome, not only bad for improving repairing efficiency, and it is difficult to ensure that two internal expanding steel
Enclose position, in terms of consistency.
Second, when strutting internal expanding steel ring, it is necessary to use special mechanically or hydraulically tool, moreover, in order to mechanical or
Hydraulic tool provides stress supporting point, needs to weld corresponding cushion block on the inner wall of internal expanding steel ring clamping opening two sides.
Third, clamping opening is the opening of equal in width, for different pipelines, internal expanding steel ring is after strutting, the width of clamping opening
Different, this just needs to prepare in advance the elastic slice of various different dimensions, and needs by repeatedly attempting just to can determine that most
Suitable elastic slice.
Fourth, internal expanding steel ring damages rubber seal zone circle since clamping opening is constantly opened, needs when strutting in order to prevent
One piece of stainless steel gasket is still further added between internal expanding steel ring and rubber seal zone circle.
Therefore, how to overcome disadvantages described above existing for internal expansion type rubber seal, be that those skilled in the art need to solve
The technical issues of.
