Abstract
The invention discloses a pipeline expansion joint and relates to the field of pipe fittings. The pipeline expansion joint comprises a telescopic pipe, a left pair of semi-annular hoops, a right pair of semi-annular hoops, sealing rubber strips, locking bolts and the like. The telescopic pipe is made of low-density polyethylene and good in axial telescoping performance. The semi-annular hoops are made of glass fiber reinforced plastics and high in annular locking force. The elastic sealing rubber strips are rubber strips which expand when meeting water and good in sealing performance. The pipeline expansion joint has the advantages that the pipeline expansion joint is used for connecting large-diameter plastic draining pipes and is a multifunctional connecting device, and the pipeline expansion joint can adapt to axial contraction and expansion deformation caused by cold contraction and thermal expansion of the plastic pipelines and can also avoid pipeline inclination caused by partial foundation sinking so as to prevent connecting port cracking and prevent leakage.
Description
Technical field
The present invention relates to plumbing fitting field, is the linkage of various large-bore plastics draining blow-off pipes.
Background technology
Large-bore plastics draining blow-off pipe has been embedded at present underground with managing as urban rainwater, sewage collecting and discharge main, because following two kinds of reasons can cause being embedded in underground pipe leakage, thereby cause environment pollution:
1. due to approximately 8 to 12 meters of the production length of every segment pipe, between manhole and manhole, distance generally has tens meters, need link together and dock with manhole again with multistage pipeline, the method of attachment adopting in engineering construction at present mainly contains thermal shrinkable sleeve and connects, Electric thermal smelting belt connects, clamp connection, enlarging socket joint connects, the Lung biopsies such as electric heating melting socket joint connection, tens mitron roads after connection can be because of the cold shrinkage and thermal expansion characteristic of plastics, the cold and hot variation of weather, make the pipeline axial after buried produce serious contraction or expansion, make between tube and tube or pipe and manhole between connectivity port deform cracking or depart from, thereby cause leakage.
2. because pipeline is buried, rear because ground produces local sinking, body can tilt thereupon, thus make between tube and tube or pipe and manhole between deform cracking or depart from and cause leakage of connectivity port.
Summary of the invention
The object of the invention is to solve the sunken leakage causing of determining of the existing method of attachment of large-bore plastics draining blow-off pipe and cause problem of environmental pollution, provide a kind of pipeline expansion joint as the reliable method of attachment of large-bore plastics draining blow-off pipe for this reason, thoroughly solved an above-mentioned difficult problem.
In order to realize above object, the present invention solves its technical barrier and is achieved through the following technical solutions.
A kind of pipeline expansion joint, is characterized in that: comprise that by a telescoping tube two double ring-shaped clips paste elastic packing adhesive tape, the formations such as lock bolt group in clip.
Described telescoping tube is that low-density polyethylene material is made, and axially two ends are provided with retaining ring, and adapter ring is to being provided with folding crest.
Described semi-circular clip body is that glass steel are made, and axially two ends are provided with groove, and hoop both sides are provided with turns up junction plate and has connecting bolt hole.
In described clip, pasting elastic packing adhesive tape is that water-swellable adhesive tape is made, and is close in the axial two ends groove of semi-circular clip and on the junction plate that turns up.
Lock bolt group adopts stainless steel bolt.
Prior art relatively, advantage of the present invention and beneficial effect are:
Solve after the buried connection of large-bore plastics draining blow-off pipe the leakage causing because of the axial shrinkage of pipeline and the expand strain cracking that causes or disengaging.
Solved after the buried connection of large-bore plastics draining blow-off pipe, because ground sink, body tilts to and makes deform cracking or depart from the leakage that causes of connectivity port.
