Abstract

The invention discloses a butting pipe sleeve of plastic socket pipes and a connection of the plastic socket pipes. The butting pipe sleeve comprises a structure in which sealing washers and the plastic socket pipes are arranged and is characterized in that a circular ring conjoined with a butting pipe sleeve outer wall is arranged in the middle of an inner cavity of the circular butting pipe sleeve outer wall; and holes at the two ends of the butting pipe sleeve are respectively horn mouths. In the connection of the plastic socket pipes, the ends of the two plastic socket pipes are respectively sleeved into the basin-shaped sealing washers; and when the plastic socket pipes sleeved into the sealing washers pass through the horn mouths, the sealing washers are compressed by the horn mouths and enter a straight pipe section of the butting pipe sleeve, so that the bottom surfaces of the sealing washers are respectively pressed against with the two side surfaces of the circular ring. When the two plastic socket pipes are connected with each other, the defects that the connecting strength of an electric hot-melting belt is not uniform, and the pipes are easy to deform and crack are overcome. The plastic socket pipes are suitable for construction in the various environments, are particularly suitable for operation in the water environment, are convenient to connect, have lower cost and reduce the labor intensity of operators.

Description

technical field [0001] The invention discloses a socket-type plastic pipe butt joint sleeve and its connection, which relates to the technical field of double-wall winding pipe socket connection pipe fittings, and is used for underground drainage pipes. Background technique [0002] In existing drainage projects, underground drainage pipes are buried, and plastic pipes are used as buried pipes. The connection methods include electric melting belt connection, clamp connection, heat shrink connection, flange connection, etc. Some connection methods have better strength. But the connection is difficult and the process is complicated. There are also some connection methods that are not suitable for working with water, and some connection plastic pipes are subsidence, which is easy to cause deformation and cracking of the pipes, especially the human factor of heating with a flame gun is very large, resulting in uneven connection strength of the plastic pipes and deformation of th...
