Abstract

The invention discloses a pipeline connecting device which comprises a pipeline connecting device body, wherein a plurality of annular steps are axially formed on an inner wall of a pipe opening of the body; a sealing ring, a sealing compression ring, a clamping tooth compression ring, a locking tooth clamping ring and an end cover which are axially and sequentially arranged are arranged on the annular steps; one end of the end cover extends out of the pipe; a connecting piece is sleeved outside the end cover; and the end cover is detachably connected with the body through the connecting piece. According to the pipeline connecting device, because the end cover is detachably connected with the body through the connecting piece, parts are greatly conveniently mounted and detached, the assembling efficiency is improved, the parts are convenient, reliable and firm to connect, the sealing performance is high, the water pressure-bearing capacity is high, the pipe joint can be easily and rapidly connected and exchanged, an auxiliary tool and sealing filler are not required, and after the pipeline connecting device is used for a long time, the phenomenon that looseness is caused and the sealing performance is reduced is avoided.

Description

technical field [0001] The invention relates to the field of pipeline connection, in particular to a pipeline connection device. Background technique [0002] Pipelines are essential infrastructure for industry. The pipeline connection device is an indispensable means of connection. [0003] At present, the well-known pipeline connections mainly include threaded connections (metal pipes) and hot-melt connections (PP-R and PE pipes, etc.). The threaded connection is to use the internal and external threads of the joint and the pipe as the screw connection, and use white paint hemp silk or polytetrafluoroethylene raw material tape as the sealing packing to seal; the hot-melt connection is to use electric heating to connect the pipe and the joint to be connected. (End faces or connection contact surfaces) heated to a molten state, and then pressed against each other, so that the homogeneous materials on the contact surfaces melt together to make them connected and sealed. Bu...
