Abstract

The invention discloses a composite water pipe, which comprises a first connecting pipe, a second connecting pipe and an intermediate connecting piece. The intermediate connecting piece has a sealed cavity in the middle, and two ends of the intermediate connecting piece are respectively provided with a connecting portion. A screw hole is provided in the middle of the connecting part, and the outer walls of the first connecting pipe and the second connecting pipe are provided with external threads, and the first connecting pipe and the second connecting pipe are all threaded into the screw hole and Together they protrude into the sealed chamber inside the intermediate connecting piece, the first connecting pipe is sealed and connected to the opposite surface of the second connecting pipe, and a negative pressure device is installed on the first connecting pipe or the second connecting pipe. The invention has a simple structure, can effectively realize the sealed connection of the connected water pipe, increases the sealing ability of the joint, prevents water leakage at the joint due to high pressure burst, double seals, increases the safety of use, and has the function of blocking and dredging.

Description

technical field [0001] The invention relates to a sewer pipe, in particular to a composite water pipe. Background technique [0002] In the prior art, the sewer pipes are assembled with each other through threads. Although the connection can be sealed, the strength here is the lowest in the whole pipe. Once the pressure of the pipe is high or it has been used for a long time, the joint will Cracks occur, causing problems of aging and water leakage. Therefore, after the pipeline is damaged, maintenance personnel are required to come and repair it. During this period, the pipeline cannot be used, which brings inconvenience to people's lives. Furthermore, sewer pipes are extremely easy to block, and it is difficult to unblock them after they are blocked. Professional plumbing repairers are needed to complete the repairs, which is a waste of time and increases daily expenses. Contents of the invention [0003] The technical problem to be solved by the present invention is to...
