Description

Technical Field

[0001] The utility model relates to the technical field of electric execution equipment, in particular to a flameproof split control box. Background Art

[0002] Electric actuators are installed in various locations on the production site. When the pipelines and valves are closely distributed, the space for operators to operate the electric actuators is extremely small, which makes operation inconvenient and makes it impossible to monitor the various parameters of the electric door display window. For example, if the temperature on site is too high, the vibration is too large, or the installation site is inconvenient, in these situations, the operator cannot or is difficult to reach, so a split structure is introduced; and the existing split structure needs to be connected through a control line after the control end and the execution structure are separated. Conventional split control boxes can only be used in ordinary occasions and are difficult to adapt to explosion-proof occasions. The existing split electric control box cavity stoppers are not uniform, installation is inconvenient, and there are many installation screws, which brings great inconvenience to production and users. To this end, we propose a flameproof split control box. Utility Model Content
