Water pipe elastic connection device, the connecting body of the device is installed on the connecting part between the pipe, and a sealing ring is installed on the inside of the end of the connecting body. The end of the pipe is inserted in the seal ring. The end of the pipe is installed with a fixed part, the front end of the fixed part is connected to the connecting body, the rear end is machined with a cone type, and the fixed part conical mouth is in the end. The water pipe on the side is fitted with an elastic jacket with an opening. The outer wall of the elastic card is conical, and the inner wall is processed with a bite ring. The connecting body is a straight through joint, a elbow, a three connection or a four connection. This technical scheme can be adapted to the connection of metal pipe and plastic pipe. The application range is wide; the sealing ring is elastic seal between the connecting body and water pipe. When the pipe is installed and used, a small amount of installation angle, length change or heat expansion and shrinkage can be taken place. The elastic deformation of the sealing ring can reduce the rigid variable of the pipe line and extend the density of the pipe. Sealing and service life; no need to use special tools for on-site connection of water pipes, simple operation and high efficiency.

水管弹性连接装置
本技术属水管连接件
,涉及一种水管弹性连接装置。
技术介绍
现有技术中,传统的金属水管一般通过直通接头、弯头或三通接头进行连接,连接方式是在连接头端头内壁加工内螺纹,在水管端头加工外螺纹,在外螺纹上缠绕密封带,将金属管外螺纹旋进连接头内螺纹内完成连接。这样的连接方式水管与水管之间是刚性连接,受热胀冷缩影响水管接头处容易损坏漏水,操作时现场需要在水管端头进行攻丝,需要携带的工具多,操作繁琐,工作效率低。随着技术的进步PVC塑料管在供水系统中大量采用,PVC塑料管的连接通常采用热熔方式实现,连接时将需要连接的塑料管和管件连接套分别插入热熔工具中同时加热,使其表面熔化,溶化后将塑料管插入管件连接套中固定、冷却,通过管件连接套实现水管的连接。这种连接方式也是固定刚性连接方式,需要施工现场有电源,使用专用的热熔工具才能实现连接,连接后水管不能拆除,安装维修不方便。
