Description

technical field

[0001] The present invention relates to an explosion-proof joint, in particular to a three-way explosion-proof joint. Background technique

[0002] In the field of explosive gas environments, explosion-proof electrical equipment is widely used, and the installation methods between various equipment are also very diverse. The explosion-proof structural parts used to connect two equipment are called explosion-proof joints. Commonly used explosion-proof joints are generally composed of two It is composed of an explosion-proof thread structure at the end, which is used to connect two explosion-proof threaded ports with the same or different ports, and can be easily connected with explosion-proof threaded ports of the same gas path. When there are three interfaces in one gas circuit, when the third interface needs to be connected, the explosion-proof joints of the two interfaces can no longer meet the requirements of use.
