Description
Technical Field
The invention relates to the technical field of plastic pipe socket connection pipe fittings.
Background
The vehicle everywhere visible pipe fitting parts comprise metal and plastic, and for plastic pipe fittings, the connection modes are mainly modes such as connection of electric melting belts, clamp connection, heat shrinkage connection, flange connection and the like, and are generally connected in a manual mode, and the strength of some connection modes is good, but the connection is difficult and the process is complex. Some are not suitable for water carrying operations, especially those heated by flame guns, which are believed to be greatly affected by operational factors. When in hot melting, as the centering mechanism is not adopted, uneven connection strength of the socket type plastic pipe and the pipe connecting sleeve and deviation of the axle center between the socket type plastic pipe and the pipe connecting sleeve occur, the end surfaces between the socket type plastic pipe and the pipe connecting sleeve cannot be guaranteed to be mutually propped, and the strength between the connection part of the socket type plastic pipe and the pipe connecting sleeve is easy to be reduced. The buried pipe of the socket type plastic pipe is deformed and cracked at the joint of the socket type plastic pipe and the connecting pipe sleeve due to uneven gravity during sedimentation, so that the engineering has to be reworked, the engineering materials and manpower are wasted, the construction period is prolonged, and the operation cost of the engineering is increased.
