Let’s take a look at the function of explosion-proof doors.

　　1. In the event of an explosion, based on the predicted blast overpressure and reflected pressure acting on the reflective surface as specified in the preliminary design, the explosion-proof door can withstand the blast pressure within this range, thereby achieving the intended protective function.

　　2. Even if the explosive event does not reach the pre-set blast intensity, the explosion-proof door can still operate normally.

　　3. In the event of an explosion, the destructive force is pre-set to allow for deformation while ensuring that the main door components remain functional, thereby preventing personnel from being trapped or cut off.

　　4. Enclosed protective function: it prevents and isolates direct thermal convection between the indoor space and the external atmosphere, thereby reducing environmental pollution from outside that could affect renovated partitions and legally protected spaces.

　　5. An explosion-proof door is a safety device that features self-closing functionality and serves as an emergency escape route.

　　I. Design Concept: To safeguard against accidental or readily occurring explosions in industrial production facilities, chemical plants, defense industry enterprises, military units, and other engineering and construction sites; to ensure the safety of personnel, the integrity of building structures, and the undamaged condition of equipment and machinery, thereby preventing harm from blast shock waves.

　　II. Operational Capabilities: The blast-resistant door system exhibits outstanding blast-resistant performance, with a blast resistance rating of 0.152 MPa, as confirmed by numerous accredited tests and inspections. The control system is designed for flexible and reliable operation, while also providing fire resistance and blast resistance.

　　III. Application Areas: These doors are typically used in public buildings, such as main and ancillary facilities in power enterprises, the petroleum industry, petrochemical plants, military installations, and other similar settings. Examples include shelters, substations, main control rooms, and emergency escape routes—specialized functional doors installed to meet safety requirements for isolating and mitigating damage from explosion sources.

　　4. Key Features: The explosion-proof door is lightweight—only half the weight of a conventional explosion-proof door. It is easy to open and close, meeting the project’s requirements for light weight and high load-bearing capacity.

　　V. Safety Equipment: The system is equipped with relevant accessories, including an explosion-proof door that automatically deploys under normal conditions of an explosion. Once personnel have safely evacuated, the door will automatically close.

　　Function of explosion-proof doors:

　　1. In the event of an explosion, based on the blast reflection surface force and the resulting ejection pressure specified in the trailer, the explosion-proof door can withstand the blast pressure within this range, thereby providing protective functionality and preventing casualties and economic losses.

　　2. Even if the explosive event does not reach the pre-set blast intensity, the explosion-proof door can still operate normally.

　　3. In the event of an explosion, the destructive force is pre-set to allow for deformation while ensuring that the main door components remain functional, thereby preventing personnel from being trapped or cut off.

　　4. Enclosed protective function, preventing immediate thermal convection between the protected indoor space and the external atmosphere.

　　5. An explosion-proof door is a safety device that features self-closing functionality and serves as an emergency escape route.
