How to achieve rapid pressure relief with explosion proof vent plug - Wuxi Sinceriend New Material Technology Co., Ltd.

Explosion proof vent plugs usually achieve rapid pressure relief in the following ways:
1. Reasonable structural design
Vent plugs are generally designed with larger vent holes or multiple ventilation channels to reduce the obstruction of gas discharge. For example, a large-diameter circular vent hole or a combination of multiple smaller square vent holes is used to allow gas to pass quickly under pressure. At the same time, the internal channel is designed to be smooth and streamlined to avoid sharp corners or narrow bottlenecks, reduce the resistance of gas flow, and allow gas to be discharged smoothly, thereby achieving rapid pressure relief.
2. Accurate pressure sensing mechanism
Equipped with high-precision pressure sensing elements, when the internal pressure of the equipment reaches the preset opening pressure value, the pressure sensing element will respond quickly. For example, using a spring-piston structure, when the pressure exceeds the set elastic force of the spring, the piston is pushed to open the vent. This mechanism can accurately open the vent plug in time when dangerous pressure comes, ensuring the timeliness of pressure relief. Moreover, some advanced vent plugs also use intelligent pressure sensing systems, which can automatically adjust the opening degree of the vent according to the rate and amplitude of pressure rise, so as to achieve more efficient and rapid pressure relief.
3. Selection of high-quality materials
The material of the vent plug usually has good strength and toughness, which can not only withstand the pressure of the normal operation of the equipment, but also quickly deform or rupture under the impact of explosion pressure to release pressure. For example, easily broken metal sheets or plastic films are used as pressure relief elements. When the pressure reaches a certain level, these elements will instantly rupture to form a pressure relief channel. At the same time, the shell material is made of high-strength alloy or engineering plastic to ensure that it will not be damaged by pressure during the pressure relief process, and to ensure the overall structural stability of the vent plug to achieve rapid and safe pressure relief.
