Problems solved by technology

[0009]Because the current multi-layer pipes are made of a mixture of metal substances such as PEX and aluminum to enhance their strength, these metal substances are usually harmful to human health, however , when this mixed material is made into a pipe, the pipe will be cut off during use, and the metal substance on the end face of the pipe will be exposed; once the pipe is inserted into the joint and comes into contact with drinking water, it may endanger human health
For the pipe joints of the above patents, when the pipe or bushing is inserted into the joint and the liquid is introduced, the end face of the pipe will be in contact with the liquid. Once the liquid is drinking water, it will directly bring great harm to the health of the human body. harm

Abstract

The invention discloses a bushing for a pipe joint. The bushing comprises a bushing body which is provided with an axial channel internally; the bushing body comprises a joint connecting section which is butt joint with the joint body and a pipe connecting section which is butt joint with the pipe; the joint connecting section is provided with a first O-shaped seal ring; the pipe connecting section is provided with a second O-shaped seal ring; the first O-shaped seal ring is used for forming seal connection with the inner wall of the joint body after the butt joint of the joint connecting section and the pipe joint; the second O-shaped ring is used for forming seal connection with the inner wall of the pipe joint in the butt joint of the pipe connecting section and the pipe; the invention also discloses a pipe joint adopting the bushing; and after the liquid is introduced in the pipe, the pipe end surface does not contact with the liquid, thus the pipe joint can not cause harm to the health of people, and has high tightness.

Description

technical field [0001] The invention relates to a pipe connection device, in particular to a bushing for a pipe joint and a pipe joint using the bushing. 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 and hot-melt connections (PP-R and PE pipes, etc.). The threaded connection is to use the joint and the pipe and its own internal and external threads for screw connection, and use the polytetrafluoroethylene raw material tape as the sealing packing to seal; the hot-melt connection is to use electric heating to heat the connecting part of the pipe and the joint to a molten state , and then pressed against each other, so that the homogeneous materials on the contact surface melt into each other to connect and seal them. The above two connection methods are cumbersome to connect,...
