Difference between explosion vent door and explosion proof door

Explosion venting doors and explosion-proof doors are both types of industrial doors. They are different in structure, use, and performance. Below we will introduce the differences between explosion-venting doors and explosion-proof doors in detail from different angles.

1. Structure

Explosion vent doors and explosion-proof doors have obvious differences in structure. Because the explosion vent needs to work in an explosion situation, its door leaf, door frame, door latch and other components need to be able to withstand huge explosion pressure. Consider the protective factor. In addition, the corners of the explosion vent door are generally thickened, and the corners are made into smooth arcs to improve its ability to withstand impacts. In contrast, the structure of the explosion-proof door is relatively simple and direct. It is essentially a door that can help isolate places with dangerous substances, and prevent the explosion generated in the explosion from affecting the surrounding areas. Because the use of explosion-proof doors is different from that of explosion-venting doors, the structure of explosion-proof doors pays more attention to functionality than to stress.

2. Purpose

The use of explosion vents and explosion-proof doors can be seen as one of the biggest differences between the two. Explosion venting doors are mainly used in hazardous places, such as chemical plants, petrochemical plants, oil refineries, etc. When an explosion occurs inside the factory, the explosion venting door can resist the high pressure generated by the explosion to reduce or avoid the effect of the explosion spreading to the surroundings. At the same time, the explosion vent door also needs to prevent secondary accidents caused by gas diffusion after the explosion. Explosion-proof doors are mainly used in places with a wide range of industries, such as light industry, shopping malls, warehouses, hospitals, etc. For example, explosion-proof doors can be used in radiology cabinets, oxygen rooms, and ward doors in hospitals to help isolate dangerous or toxic substances and protect the safety of surrounding staff and patients. In addition, explosion-proof doors generally have the functions of fire prevention and smoke prevention, which can play a good role in isolation when a fire occurs.

3. Performance

Explosion vent doors and explosion-proof doors are naturally very different in terms of performance. Explosion venting doors can withstand great pressure and heat. The door leaf and door frame need to adopt special structural design, and the material must be higher than that of ordinary doors. For example, steel or aluminum alloy can be used to meet special environments. demand. The performance of explosion-proof doors is mainly reflected in many aspects such as isolation performance, fire prevention, and smoke prevention. Usually, a special closed design is adopted to ensure that dangerous or toxic substances will not leak out. In addition, the explosion-proof door also needs to have certain waterproof and moisture-proof performance. The performance requirements of the explosion vent door are relatively simple, mainly needing to be able to withstand the pressure normally during the explosion, and to prevent possible dangers such as gas diffusion after the explosion.
Through a detailed analysis of the structure, use and performance of explosion-venting doors and explosion-proof doors, it can be seen that the difference between the two types of doors is quite significant. On the one hand, explosion-proof doors use more demanding materials and complex structures, so their costs are relatively high; on the other hand, explosion-proof doors have wider application scenarios, stronger usability, and relatively low prices, which are suitable for some ordinary places . Of course, whether it is an explosion-proof door or an explosion-proof door, it has its own unique application scenarios, and it needs to be selected according to the actual situation. At the same time, whether it is an explosion venting door or an explosion-proof door, its design and manufacture need to attach great importance to the knowledge level and technical strength of experts and technicians in related fields to ensure the quality and effect of the product.
