Description

Flexible connecting device for glass fiber reinforced plastic pipeline

Technical Field

The utility model relates to a pipeline compensation arrangement, specific glass steel material pipeline flexible coupling device that says so.

Background

The flexible connection device is also called a connector or a compensator, is mainly used in the middle of a heat delivery pipeline for compensating the deformation amount of the pipeline during cold and hot telescopic deformation, and is one of important components for ensuring the safe transportation of the pipeline. The outer surface of the main body of the flexible connecting device is corrugated and is a corrugated pipe, the two ends of the main body are both provided with connecting end faces, and a connecting rod body is connected between the two connecting end faces. When the high-pressure pipe is used in a high-pressure use scene, the pipe body is pressed greatly in work, so that the pipe wall of the pipe body is thick, the strength requirement is high, and a main body is generally made of metal steel. In the actual use process, the corrugated concave edge of the pipe body can generate metal fatigue under the telescopic action, so that cracks are generated, and finally the leakage of the flexible connecting device is caused.

In addition, in some use scenes, the existing flexible connection device contains fluorine, boron, acid, alkali, water vapor and the like, the outer surface of the pipeline needs to be weather-resistant, and at the moment, the pipe body of the metal steel is easy to corrode.

Based on the above situation, the service life of the existing flexible connection device is short, the flexible connection device is often required to be replaced only about two months, time and labor are wasted, the maintenance cost is high, and a large improvement space exists.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough that prior art exists, provide a pipeline flexible connection device who improves the durability when using multilayer composite construction in order to guarantee glass steel material pipeline structural strength.

In order to achieve the above object, the utility model adopts the following technical scheme: a glass fiber reinforced plastic pipeline flexible connection device comprises a pipe body, a left flange and a right flange, wherein the left flange and the right flange are respectively arranged at two ends of the pipe body, and the left flange and the right flange are fixedly connected with the pipe body into a whole; the inner pipe surface of the pipe body is arc-shaped, and a plurality of annular reinforcing ribs are arranged on the outer pipe surface of the pipe body; the pipe body is fixedly connected with the annular reinforcing rib into a whole; the annular reinforcing ribs are made of glass fiber reinforced plastic; the pipe wall of the pipe body is of a multilayer composite glass steel structure and comprises an inner layer, a secondary inner layer, an intermediate layer, a secondary outer layer and an outer layer, wherein the inner layer, the secondary inner layer, the intermediate layer, the secondary outer layer and the outer layer are tightly matched and are connected into a whole through resin adhesion, so that a compact and complete pipeline structure is formed; the inner layer and the outer layer are both of solid structures formed by mixing a plurality of layers of woven glass fibers with resin and then curing the resin; a secondary inner rubber layer; the secondary outer layer is a metal tube.

Furthermore, a plurality of groups of mounting bosses are arranged on the outer wall surface of the pipeline, and the opposite mounting bosses are connected and matched through screws.

The utility model discloses during the implementation, utilize glass steel material to combine composite construction to realize the compound body of high strength, inside and outside all can be corrosion-resistant, the protruding movable deformation volume that acts as in the inner arc of recycling body can effectively reduce the stress that forms in trough department in the use to increase of service life can improve the fatigue resistance ability of compensator, not only low in manufacturing cost, installation and maintenance are convenient, have improved security and reliability moreover.
