Embodiment 1

[0010] A three-way explosion-proof joint, characterized in that: the main body of the three-way explosion-proof joint is T-shaped, one end of the T-shaped horizontal long side is an explosion-proof external thread and the other end is an explosion-proof internal thread, and the rest of the cross-section outside the external thread is square; T The vertical short side of the type is flameproof internal thread, and the cross section is circular; the three horizontal and vertical flameproof threaded ports can be connected to three explosion-proof ports.

Embodiment 2

[0012] In the present invention, the main body of the three-way explosion-proof joint is T-shaped, and the material is stainless steel. One end of the long horizontal side of the T-shape is an explosion-proof external thread and the other end is a flame-proof internal thread, and the rest of the cross-section of the external thread is square; the vertical short side of the T-shape is an explosion-proof internal thread, and the cross-section is circular. Three horizontal and vertical flameproof threaded ports can be connected to three flameproof ports, and the square cross-section structure can hold a wrench for easy installation.

Embodiment 3

Abstract

The invention discloses a three-way explosion-proof joint, which is characterized in that: the main body of the three-way explosion-proof joint is T-shaped, one end of the T-shaped horizontal long side is an explosion-proof external thread and the other end is an explosion-proof internal thread, and the other cross-sections of the external thread are Square shape; the short vertical side of the T-shape is an explosion-proof internal thread, and the cross-section is circular; the three horizontal and vertical flame-proof threaded ports can be connected to three explosion-proof ports. The invention can realize the assembly of three explosion-proof interfaces, not only has reliable explosion-proof performance, but also has a simple structure and is convenient for installation.

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. Contents of the invention [0003] In o...
