Explosion-proof windows and doors are designed to resist the occasional explosive forces from external installations in industrial buildings, ensuring the normal operation of personnel and internal equipment within the industrial structure without damage from the shock waves. They also prevent the continuation of explosion damage. What are the functions and maintenance aspects of explosion-proof windows and doors?

The Function of Explosion Relief Windows and Doors

Under爆破conditions, the blast entry pressure and reflection force are in accordance with the pre-set parameters. Explosion relief windows and doors can withstand the blast pressure within this scale, thereby achieving the protective effect.

After the blasting condition occurred, the blast force did not reach the pre-set level; the explosion-proof windows and doors can be used normally.

3. Upon the occurrence of an explosion, the explosive force reaches the pre-set level, causing deformation, but the components of the explosion relief windows and doors can still be used to prevent personnel from being trapped.

4. The enclosed barrier function prevents direct air exchange between the enclosed space and the external air, thereby reducing external contamination of the isolated and protected area.

Maintenance of Explosion Relief Windows

Do not alter the membrane material and thickness of the explosion relief windows; they must be executed according to the design plan.

2. Explosion relief windows should not use whole membrane panels except for the slotted aluminum panels; they also require a single-jawed jointing method, with the joint positions adhering to the design standards.

3. Explosion relief windows and doors should have open screw holes around the perimeter to minimize resistance when pressure is released; there should be asbestos rope or other sealing materials between the door body and the flange, and the pressure ring should be securely fastened with screws to ensure a tight seal.

4. Rust and peeling paint on explosion relief windows and doors should be promptly coated and repaired; if there is rust on the moving parts of the explosion relief windows and doors, they should be wiped clean and re-oiled. Any de-gummed sealant strips should be replaced promptly.

5. After the explosion relief door blast, the cause should be investigated; the repaired explosion relief doors and windows can be restarted. When replacing or inspecting the explosion relief doors and windows, the powder-making system must be stopped, and precautionary measures should be taken.
