Reinforcement device and reinforcement method for joints of antibacterial water pipes

Abstract

The invention discloses a reinforcement device and a reinforcement method for the joint of an antibacterial water pipe, comprising an antibacterial water pipe and a reinforcement device, the reinforcement device comprising an upper arc-shaped plate and a lower arc-shaped plate that cooperate with each other, and the materials of the two arc-shaped plates are Same as the antibacterial water pipe, both ends of the two arc-shaped plates are integrally connected with fastening plates, and the bottom surfaces of the two arc-shaped plates are attached and fixed with matching silicone heating sheets, and the two ends of the silicone heating sheets extend To the end face of the fastening plate, several threaded rods are distributed in a matrix on both sides of the width range of 5-10mm in the middle of the silicone heating sheet. One end of the several threaded rods passes through the silicone heating sheet and extends vertically to the inside of the arc-shaped plate, and the exposed length of the other end is antibacterial water. One-third of the pipe wall thickness, several threaded rods are threaded with nuts that fit with the silicone heating sheet, and several threaded rods are located in the arc surface of the arc-shaped plate, and the silicone heating sheet is provided with a wire. Effectively enhance the tensile and shear strength of the joints of antibacterial water pipes and reduce the occurrence of cracks.

Description

technical field [0001] The invention relates to the technical field of antibacterial water pipes, in particular to a reinforcement device and a reinforcement method for joints of antibacterial water pipes. Background technique [0002] Antibacterial water pipes are water supply and drainage pipes. With the continuous acceleration of urbanization and the gradual improvement of people's economic level, the demand for tap water has increased significantly, so the demand for tap water supply and drainage pipes is increasing. ; With the increasing demand for antibacterial water pipes for tap water, the demand for antibacterial water pipe connection devices is also steadily increasing. [0003] As the carrier of drinking water, antibacterial water pipes need to be used in large quantities. PE antibacterial water pipes are the most frequently used. PE pipes are currently in the municipal pipe market in China. Plastic pipes are developing steadily. PE pipes, PP-R pipes, and UPVC pip...

AI Technical Summary

Problems solved by technology

When processing different types of PE pipes, according to the different application conditions, the corresponding resin grades are selected, and the requirements for extruders and molds are also different. The polyethylene pipe systems are connected by electrothermal fusion, and the strength of the joints is high. Depending on the strength of the pipe body, the connection steps are: clamp and clean the port, adjust and grind the port, straighten the port, apply pressure to weld, and release pressure to cool. In the long-term practical process, due to external forces, the antibacterial water pipe will be cut. Cutting force or pulling force, and the reinforcement device at the connection of the existing antibacterial water pipe is unreasonable in design and unreliable in firmness, and there will be cracks or breaks in the joint of the antibacterial water pipe, causing drinking water leakage, resulting in waste of resources, and easy to carry to safety hazard
