Abstract

The invention discloses a large-caliber tapered inserted electric heat fusion type plastic pipe. The plastic pipe comprises a pipe body, a socket end, a plug end and an electric heating piece. The socket end is arranged at one end of the pipe body, and the plug end is arranged at the other end of the pipe body. The socket end is in a funnel shape. The plug end is in a conical shape. The slope of the conical surface of the plug end is consistent with the slope of the inclined face of the funnel of the socket end. The electric heating piece is installed at the socket end and / or the plug end. The plug end and the socket end are of the inclined face design, and after the caliber is changed, only the plug end needs to be inserted in the socket end, and then fusion faces can be closely attached. In addition, the principle of the conical center positioning is utilized, the slope of the cone of the plug end is consistent with the slope of the socket end, and the function of positioning the plug end can be achieved; and it is ensured that butt fusion cannot be eccentric, and the electric heating fusion quality between connectors is improved.

Description

technical field [0001] The invention belongs to the field of plastic pipe industry and pipe connection technology, in particular to a large-caliber tapered socket electric hot-melt plastic pipe. Background technique [0002] At present in our country, the connection of large-diameter and super-large-diameter drainage and sewage structural wall pipes mostly uses heat shrinkable tape or electric melting tape. Pipe connections with a diameter of more than one meter are only connected with a few millimeters thick heat-shrinkable tape, and the connection is easily damaged, causing leakage accidents. Since the ground is moving, there must be subsidence, and the connection of the heat shrinkable belt is easy to lose its function when the ground subsides. Large-scale collapses often occur in many cities, and the reason for chasing them all is caused by the leakage of large-caliber pipelines. [0003] In the past, the technology of connecting plastic pipes by electrothermal fusion ...
