Description
Technical Field
The utility model relates to a pipe joint device technique, in particular to pipe connection spare.
Background
The connection mode of the existing plastic pipeline generally has three novel pipeline connectors: the adhesive method is mainly used for connecting hard PVC pipe and ABS pipe, and is characterized by that the socket and spigot are coated with adhesive, the spigot is extruded into the socket, after the adhesive is solidified, the solvent adhesive used is mostly solution of PVC in tetrahydrofuran or cyclohexanone, and its required viscosity is moderate, and its minimum viscosity at room temp. is 90 Pa.S.
Secondly, the welding method is mainly used for polyolefin pipes such as LDPE, HDPE and PP pipes, and has higher technical requirements on operation and unsatisfactory effect during welding.
And thirdly, the threaded connection is safe and reliable, but the wall thickness of the pipe fitting must be thicker than that of the pipe fitting by a solvent method due to the need of threading, and the connection method needs additional processing of a pipeline, so that the process is complicated and the cost is high.
