Problems solved by technology

Since the traditional alarm control device usually adopts a non-explosion-proof structure design shell as the equipment in the control room, when the working conditions on the site are complex, it is easy to use the space inside the control room to generate flammable or toxic and harmful gases, which will cause harm to people and the site. Equipment poses a safety hazard

Abstract

The invention discloses an anti-explosion alarm control shell device which comprises an upper cover and a lower shell. The anti-explosion alarm control shell device is characterized in that the bottom of the upper cover is connected with the top of the lower shell through bolts, the lower shell is provided with cable introducing devices, and the connecting part of the upper cover and the lower shell serves as a welding isolating joint surface. The anti-explosion alarm control shell device has the advantages that the alarm control shell of an explosion-proof structure is adopted, and therefore not only is field personnel and equipment safety guaranteed, but also the shell is high in strength and durable.

Description

technical field [0001] The invention relates to an explosion-proof alarm control shell device, in particular to an explosion-proof alarm control shell device with a visible window. Background technique [0002] In industrial gas detection and alarm control equipment, the alarm control device is often used as a control and monitoring device, which is arranged inside the control room for real-time monitoring of the concentration and realization status of each detected gas in the job site. Since the traditional alarm control device usually adopts a non-explosion-proof structure design shell as the equipment in the control room, when the working conditions on site are complex, it is easy to use the space inside the control room to generate flammable or toxic and harmful gases, which will cause harm to people and the site. The device poses a safety hazard. Contents of the invention [0003] In order to solve the safety problem of the above-mentioned background technology, the ...
