Description

Detachable sealing connection device for pipes of two different materials

technical field

The utility model relates to a connection device, in particular to a detachable sealing connection device used for pipes of two different materials.

Background technique

In daily production and life and scientific research experiments, it is inevitable to encounter situations that require connections between different pipe materials.

At present, commonly used pipe connection methods include threaded connection, flange connection, adhesive connection, ferrule connection, hot-melt connection and other forms. However, for metal pipes and non-metal pipes, especially the connection between metal pipes and quartz glass pipes, threaded connections, flange connections and hot-melt connections are not easy to process or cannot be realized, while adhesive connections and ferrule connections cannot guarantee the connection strength at the same time And sealing performance, especially in scientific research experiments that require high connection strength and high sealing performance, and sometimes need to arrange measuring points.

The patent number is 200710009502.0, and the invention is named "A Pipe Connecting Device". A pipe connecting device described in it includes a pipe joint with a cavity and at least two threaded connection ends communicating with the cavity and a threaded connection. The pipe connection is realized by fitting the threaded connector on the pipe with flanging and threading it with the pipe joint. Although the damaging thread processing of the connecting pipes is avoided, flanging processing is required for the connecting pipes, and it cannot meet the requirements for the arrangement of measuring points in scientific research experiments.

Therefore, there is an urgent need to develop a connecting device between different pipes that is simple in processing, easy to use, does not need to be processed to connect pipes, and can fully ensure the connection strength and sealing performance.
