Bamboo composite pipe connecting structure and preparation method thereof

Abstract

The invention discloses a bamboo composite pipe connecting structure and a preparation method thereof and belongs to the technical field of bamboo composite pipe connection. One end of each bamboo composite pipe is set as a pipeline socket with a blocking platform and a sealing groove, and the pipeline sockets on the two corresponding to-be-connected bamboo composite pipes are set as cylindrical bundle sections, so that the pipeline sockets of the two bamboo composite pipes are inserted at the two ends of the bundle sections and corresponding connection of the two bamboo composite pipes is realized. The bamboo composite pipe connecting structure provided by the invention is simple in structure and convenient and rapid in preparation process; the process defect in the existing bamboo composite pipe connecting structure forming process can be effectively overcome; waste products of forming parts are reduced; waste of materials are reduced; the preparation cost and the application cost ofthe bamboo composite connecting structure can be saved; and good application prospect and promotion value are achieved.

Description

technical field [0001] The invention belongs to the technical field of bamboo composite pipe connection, and in particular relates to a bamboo composite pipe connection structure and a preparation method thereof. Background technique [0002] In people's daily life and industrial production, pipelines are widely used. Common pipeline connection methods include threaded connection, flange connection, welding, pipe socket connection, ferrule connection, hot melt connection and groove connection. These connection methods are widely used in various pipeline projects in many fields. However, for bamboo composite pipes, bamboo is used as the main raw material. Due to the particularity of bamboo, the existing interface connection methods cannot be effectively applied. [0003] At present, most of the bundle joints used for pipeline connection need to be matched with threads to achieve a sealed connection, and are usually used as the connection of metal pipes or plastic pipes, suc...

Problems solved by technology

However, during the testing and application of the above-mentioned tube bundle section structure, the researchers found that there are certain defects in the forming process of the above-mentioned tube bundle section structure: the installation groove of the sealing ring of the tube bundle section serves as the stress concentration point of the bundle section structure, and it is difficult to adopt the above-mentioned The forming method in the prior patent is one-time forming. Since the rubber ring is thin and soft, it is easy to form an arc surface instead of a right-angle surface at the position of the sealing ring installation groove when the bundle joint is wound and formed, and the bundle joint cannot pass through after forming. Process the sealing ring installation groove at the time of cutting and grinding, otherwise it will damage the inner lining surface of the bundle joint and affect the waterproof and aging resistance of the bundle joint

In addition, the technology of connecting bamboo composite pipes by bundle joints in the previous patents does not have sufficient limit measures, which may easily lead to longitudinal displacement of bundle joints and affect the stability and reliability of bamboo composite pipe connections
