Abstract

The invention discloses a wear-resistant and anti-corrosion PVC plastic pipe set, which comprises a pipe fitting joint and a plastic pipe fitting connected and fixed through the pipe fitting joint. The outer surface of the side wall of each pipe fitting joint is close to the joint with the plastic pipe fitting and is provided with a limited fixing platform. , the inner surface of the side wall of the joint end of the pipe fitting has a limit hole extending to the inner cavity of the pipe fitting, the limit fixing platform is located directly above the limit hole, and the outer surface of the side wall of the plastic pipe fitting is provided with a hole corresponding limit slot. In the present invention, a limit fixing platform is arranged on the pipe joint, and an elastic limit seat is installed on the limit fixing platform, and the limit rod in the elastic limit seat is directly inserted into the groove on the surface of the plastic pipe through the pipe joint. Among them, it can effectively prevent the movement of the plastic pipe fittings, so that the reverse force accidentally applied during the long-term use of the pipe fittings will not easily cause the plastic pipe fittings to come out of the joints due to vibration, movement, etc., without frequent maintenance, reducing labor strength.

Description

technical field

[0001] The invention belongs to the field of plastic pipe kit preparation, and relates to a wear-resistant and anti-corrosion PVC plastic pipe kit and a preparation method thereof. Background technique

[0002] Plastic pipe kits generally include connectors and plastic pipe fittings. In order to facilitate disassembly, the connectors and plastic pipe fittings are usually fixed by threaded connections. Inadvertently applied reverse force will easily cause the plastic pipe fittings to come out of the joint, and then cause material leakage at the joint of the plastic pipe set, which requires frequent inspection and tightening, which is inconvenient to use and increases labor intensity.

[0003] Due to the high corrosion resistance of PVC, it is usually widely used in oil transportation tanks and acid-base transportation pipes, but the heat resistance and aging resistance of PVC itself are low, and the pipe fittings will age when exposed to the sun for a long tim...
