Connecting sleeve piece structure for connecting polyethylene pipes

Abstract

The invention discloses a connecting sleeve piece structure for connecting polyethylene pipes. The connecting sleeve piece structure comprises a pipe body which is made of a polyethylene material. The two ends of the pipe body are inserted into the end heads of the two polyethylene pipes to be connected correspondingly. An electric heating element is pre-embedded in the pipe body. When the end heads of the polyethylene pipes to be connected are inserted into the ends of the pipe body, the electric heating element gives out heat so that the end heads of the polyethylene pipes to be connected and the ends of the pipe body can be connected together through fusion. According to the connecting sleeve piece structure for connecting the polyethylene pipes, the electric heating element is pre-embedded in the pipe body so that the ends of the pipe body 1 can be heated to be molten in a more balanced mode; and in particular, the part, making contact with the end heads of the polyethylene pipes to be connected, of the inside of the pipe body can be heated more directly, and therefore the condition that the ends of the pipe body are heated to be damaged is effectively avoided, the connecting speed is increased, connecting efficiency is improved and field operation is greatly facilitated.

Description

technical field [0001] The invention relates to a connection sleeve structure, in particular to a connection sleeve structure for connecting polyethylene pipes. Background technique [0002] In actual use, polyethylene pipes often need to be cut and spliced. For this reason, a series of splicing tools have been born. [0003] Among them, the electric heating connection method is the most common. The so-called electric heating connection is to put the connection set on the end of the polyethylene pipe to be connected, and then use a separate electric heating element to heat the outer ring of the connection set. When the connection set reaches the melting critical state, the electric heating element is removed, and after a certain period of cooling, the connection set is integrated with the ends of the polyethylene pipes to be connected, thereby realizing the splicing of the polyethylene pipes to be connected. [0004] The above-mentioned connection method of heating the out...
