Problems solved by technology

[0002] At present, the connection methods of aluminum-plastic composite pipes used in the field are mostly socket type, flange type or pipe end threaded type. The connectors used are generally made of metal materials. During the period, the joints were prematurely damaged and leaked due to corrosion, resulting in losses. Moreover, the site construction speed was slow during installation, and the labor intensity of the construction personnel was high.
In addition, the construction time of these three methods is long, and related construction tools are required, which has high requirements for construction operators, complicated operation, prone to operational errors, and time-consuming installation.

Abstract

The invention discloses an aluminum-plastic composite tube quick joint which comprises a sleeve and a connection part. The quick joint is characterized in that the connection part comprises an inner steel strip layer and a glass fiber plastic layer from outside to inside in an integral forming mode; the sleeve is provided with a pipeline insertion groove and an outward outer flange; an inverted kerf is formed in the pipeline insertion groove; the interior of the inverted kerf is sequentially provided with a clamped connection element and a locking ring in sequence from the bottom of the pipeline insertion groove to a notch; the groove wall of the inverted kerf and the outer wall of the locking ring are conical faces and make contact with each other; the inner wall of the glass fiber plastic layer is provided with an inner groove matched with the outer flange. The aluminum-plastic composite tube quick joint is quick in installation, resistant to corrosion and easy to operate.

Description

technical field [0001] The invention relates to a pipe joint, in particular to an aluminum-plastic composite pipe quick joint. Background technique [0002] At present, the connection methods of aluminum-plastic composite pipes used in the field are mostly socket type, flange type or pipe end threaded type. The connectors used are generally made of metal materials. During the period, the joints were prematurely damaged and leaked due to corrosion, resulting in losses. Moreover, the site construction speed was slow during installation, and the labor intensity of the construction personnel was high. In addition, the construction time of these three connection methods is long, and relevant construction tools are required. The requirements for construction operators are relatively high, the operation is complicated, and operation errors are prone to occur, and installation is time-consuming. Contents of the invention [0003] The object of the present invention is to provide ...
