The mechanical explosion-proof valve is a flame explosion-proof device installed on dust collectors, cyclone separators, and other air ducts. It has a simple design, is economical and reliable, and is selected according to the diameter of the air duct (different air duct diameters correspond to different models of mechanical explosion-proof valves). ), mainly used to隔断 the flames and shock waves generated by explosions, preventing them from being transmitted to upstream equipment, protecting the safety of front-end facilities.

Device Description
Device Description

The core working logic of the mechanical explosion-proof valve revolves around airflow guidance and explosion impact response:
The core working logic of the mechanical explosion isolation valve operates around airflow direction and explosion shock response:

u Normal working condition (normally open state): When the system is operating normally, due to the airflow in the duct (such as the directional airflow generated by negative pressure extraction), the valve plate remains in the open state, not obstructing normal ventilation and process flow;
Normal working condition (Normally open state) : During normal system operation, due to the directional airflow (e.g., negative pressure ventilation) in the air duct, the valve flap remains open, without hindering normal ventilation and process flow;

u Explosion Trigger (Rapid Shutdown): When an internal explosion (or reverse airflow impact, essentially an explosive shock) occurs within the device, the valve plate closes instantly under the action of the shock wave, blocking the propagation path of the explosive flame, heat, and pressure. For example: installed on the duct between the rear filter and the large cyclone, when the rear filter explodes, it can prevent the explosion from transferring to the large cyclone; if installed on the duct between the cyclone separator and the powder spraying room, an explosion in the cyclone separator will not endanger the powder spraying room;
Explosion trigger (Quickly close) : When an explosion occurs inside the equipment (or reverse airflow shock, essentially an explosion shock), the valve flap closes instantly under the action of shock waves, blocking the propagation path of explosion flames, heat, and pressure. For example: Installed on the air duct between the after-filter and the large cyclone, if an explosion occurs in the after-filter, it can prevent the explosion from transmitting to the large cyclone; if installed on the air duct between the cyclone separator and the powder spray booth, an explosion in the cyclone separator will not endanger the powder spray booth;

u System Shutdown (Keep Open): When the system stops operating, the back pressure valve remains in the open state, which does not affect the daily start-up, shutdown, and maintenance of the equipment.
System shutdown (Remain normally open) : When the system stops operating, the back-pressure valve flap remains open, without affecting daily startup, shutdown, and maintenance of the equipment.

Functions and Features
Functions and features

(1) The core function of flame and shock wave isolation is to block the propagation of explosive flames and shock waves, protecting upstream equipment (such as large cyclones, powder spray booths, etc.) from the impact of explosions.
The core function is to block the propagation of explosion flames and shock waves, protecting upstream equipment (e.g., large cyclones, powder spray booths) from explosion impact.

(2) The airflow adaptation under normal conditions keeps the airflow open, explosionI'm sorry, but it seems that there is no text provided for translation. Please provide the text you would like me to translate.Reverse airflow triggers rapid closure, accurately responding to different airflow conditions.
Remains open due to airflow under normal conditions, and closes quickly when triggered by explosions or reverse airflow, responding accurately to different airflow states.

(3) Chain sensor compatibility (optional) can integrate sensors to monitor operating conditions, supports chain control with the system, and extends equipment maintenance cycles (customization required).
Can integrate sensors to monitor operating conditions, support interlocking control with the system, and extend equipment maintenance intervals (custom function required).
