[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. This type of high-temperature resistant and high-load explosion-proof door has a reinforcement frame and a reinforcement plate inside the door leaf body that are both made of high-strength steel, which can increase the overall load-bearing capacity of the explosion-proof door. At the same time, the filling layer on the outside of the reinforcement plate is a mixture of ceramic fiber and carbon fiber composite materials, which has excellent high-temperature resistance and heat insulation performance. A protective layer made of aluminum alloy is provided inside the door leaf body to ensure that the door leaf can maintain its integrity when subjected to pressure or impact. Through the coordination of the reinforcement plate, the filling layer and the protective layer, the explosion-proof door is suitable for environments that require high safety and fire resistance, ensuring the safety of personnel and facilities in dangerous environments;

[0012] 2. This type of high-temperature resistant and high-load explosion-proof door has multiple sets of ventilation holes on the door leaf body. When the external wind pressure comes into contact with the door leaf body, the wind force can push the rubber plug in the ventilation hole. At this time, the rubber plug can squeeze the spring on one side through the ventilation plate. Due to the reaction force of the squeezed spring, the rubber plug can be pushed through the ventilation plate and the wind pressure inside the door leaf body can be discharged through the air outlet, thereby reducing the wind force and pressure on the entire door leaf body, improving the overall impact resistance of the explosion-proof door, and further improving the safety of the explosion-proof door.
