Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] In the embodiment of the present invention, the outer layer of the composite sleeve joint is a glass fiber reinforced plastic layer, and the inner layer is a rubber sealing layer. The glass fiber reinforced plastic structure layer and the rubber sealing layer have good integrity and are not easy to delaminate. When the pipes are connected, the quality of the interface is stable and reliable. The rubber will not shift, which overcomes the problem that the rubb...

Abstract

The invention discloses a composite sleeve joint which takes the shape of a drum with the two ends open. The composite sleeve joint comprises an inner drum layer and an outer drum layer which is tightly attached on the outer circumference of the inner drum layer. The inner drum layer is made of rubber and the outer drum layer is made of glass fiber reinforced plastic. According to the invention, the outer layer of the composite sleeve joint is a glass fiber reinforced plastic layer and the inner layer is a rubber sealing layer; the glass fiber reinforced plastic layer and the rubber sealing layer are of good integrality, and the layers are not easy to peel; when the sleeve joint is used to connect pipes, the connection joint is stable and reliable in quality and the phenomenon of displacement of the rubber cannot happen; so the sleeve joint overcomes the problem that when a flexible socket O-shaped rubber seal ring is used for connection, the rubber seal ring is easy to twist and displace, which affects the sealing effect of the joint. In addition, the invention further provides a manufacturing method of the composite sleeve joint.

Description

technical field [0001] The invention relates to water supply and drainage engineering technology, in particular to a composite sleeve joint and a manufacturing method thereof. Background technique [0002] There are many types of pipes used in the existing water conservancy and municipal pipe network projects, including traditional pipes such as steel pipes, cast iron pipes, and concrete pipes, as well as new pipes such as glass fiber reinforced plastic pipes and plastic pipes. The connection methods of pipes generally adopt flexible connection or rigid connection. way. [0003] When the flexible connection is adopted, the "O" rubber ring socket connection is mainly used. During installation, the "O" rubber ring rubs against the inner surface of the pipe socket, and the "O" rubber ring is easily twisted and displaced in the rubber groove, which affects the joint seal. Effect. Contents of the invention [0004] The technical problem to be solved by the embodiments of the ...
