Continuously knitted composite wound glass reinforced plastic pipe straight joint

Abstract

The invention discloses a continuously knitted composite wound glass reinforced plastic pipe straight joint, which comprises a middle connector and a middle connecting piece and an inner pipe connecting piece that are symmetrically installed at the upper end and the lower end of the middle connector. Sealing adjusting mechanisms are evenly arranged on the outer wall of a pipeline of the inner pipeconnecting piece at equal intervals. The top of the middle connecting piece is connected to a flexible connecting pipe, and a locking mechanism is installed on the outer wall of a flexible connectingpipe. The continuously knitted composite wound glass reinforced plastic pipe straight joint provided by the invention can realize rapid installation, also can adapt to different pipe diameters, savesthe installation space, and can be designed into different joint forms to meet any pipe distribution requirement. Meanwhile the sealing performance between two sets of pipelines can be guaranteed after installation.

Description

technical field [0001] The invention discloses a direct joint of continuous knitting composite drawn glass steel pipes, in particular to the technical field of joints of conveying pipelines. Background technique [0002] With the development of my country's economy, the safety requirements for municipal engineering, building water supply and drainage, power system, chemical industry, communication, and water conservancy irrigation are also increasing, so it is more important to choose a better pipeline. For a long time, transportation pipelines have been made of metal materials, such as steel pipes, iron pipes, etc. Traditional metal pipelines consume a lot of energy in the production process, have many processes, and in the actual use process are wet, dirty, and coastal salt. The shortcomings of metal conductivity, easy to rust, short service life, and high facility maintenance costs in harsh environments such as fog have gradually been eliminated and replaced by pipes of v...

Problems solved by technology

For a long time, transportation pipelines have been made of metal materials, such as steel pipes, iron pipes, etc. Traditional metal pipelines consume a lot of energy in the production process, have many processes, and in the actual use process are wet, dirty, and coastal salt. The shortcomings of metal conductivity, easy to rust, short service life, and high facility maintenance costs in harsh environments such as fog have gradually been eliminated and replaced by pipes of various new materials. Now the common ones on the market are pipes wound and formed by glass fiber reinforced plastic composite materials. Extruded PVC, PE, PP and other plastic pipes and various plastic corrugated pipes

[0003] With the emergence of a new type of FRP reinforced pipe, the use of traditional joints at its joints can no longer meet the requirements of use. The connection of FRP reinforced pipes cannot be welded like plastic pipes. If plastic flat pipes are used for glue bonding, Due to the existence of corrugation, its tightness is poor
