Explosion proof valve is normally used on the inlet pipeline of dust collectors or cyclone separators. It is a simple, economical and reliable explosion-proof product, mainly used to block the flame and shock wave generated by internal explosion of equipment from transmitting to upstream pipelines and equipment. During operation, the valve disc of the one-way explosion-proof valve is opened by the normal working airflow in the pipeline or is in a normally open state. In the event of an explosion inside the protected equipment, the valve disc of the explosion-proof valve is closed due to the impact of the shock wave.

Explosion proof device for one-way explosion-proof valve of dust removal boxPrinciple:

Under normal operating conditions of the system, the internal back pressure valve disc floats up due to the airflow and spring force in the pipeline, and the explosion-proof valve opens. When the system is stopped, it remains in the open state under the spring force of the back pressure valve disc. When a dust explosion occurs, the shock wave is at the front end of the flame. The explosion-proof valve is quickly closed by the shock wave generated by the explosion and locked by a self-locking mechanism to prevent the valve disc from opening and prevent the spread of flame and pressure waves. After the explosion is over, it can be manually reset and can be reused after simple maintenance. During normal operation, the valve disc is opened by an auxiliary opening device. Installation of one-way explosion-proof valve for pipeline

Explosion proof valves are widely used in industries such as wood processing, plastics, tobacco, spraying, food and dairy products, pharmaceuticals, coal processing, plastic and fuel processing, electricity, cement, etc.

Dust explosion requires five elements, and when these five elements coexist, there is a possibility of explosion occurring. The five elements are as follows: oxygen; Combustible dust; Fire source; Dust cloud; confined space

Dust explosion is accompanied by strong shock waves and flames. Due to the lack of pressure resistance of the equipment, it will be damaged during the explosion, resulting in the risk of secondary or multiple explosions. So we are required to pay attention to dust explosion protection.

In order to prevent equipment from generating dust explosions or to avoid greater harm in the event of dust explosions, explosion-proof pressure relief equipment is particularly important.

Explosion venting is one of the commonly used and effective methods of explosion protection; Release pressure during potential industrial explosions and provide a well-designed pressure release!
