Explosion proof valve
A normally closed one-way explosion-proof valve is characterized in that it includes a valve cover, a valve disc, and a valve body pipe flange. The valve cover is connected to the upper part of the valve body through a shaft, and the action of the valve disc is controlled by the airflow of the downstream fan of the dust removal equipment. When the fan starts working, the valve disc will slowly open and reach a state where medium can be transmitted after a period of operation.

Product Description
Unidirectional explosion-proof valve:
A normally closed one-way explosion-proof valve is characterized in that it includes a valve cover, a valve disc, and a valve body pipe flange. The valve cover is connected to the upper part of the valve body through a shaft, and the action of the valve disc is controlled by the airflow of the downstream fan of the dust removal equipment. When the fan starts working, the valve disc will slowly open and reach a state where medium can be transmitted after a period of operation.
The working principle of the explosion-proof valve:
When a dust explosion occurs, the shock wave is at the front end of the flame. The explosion-proof valve quickly closes due to the shock wave generated by the explosion and is 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 completed, it is manually reset and can be reused after simple maintenance. During normal operation, the valve disc is opened by an auxiliary opening device
Working principle of explosion-proof valve:
Explosion proof valve is a mechanical device designed to prevent the propagation of explosive flames and pressure between process equipment pipelines.
With the development of modern industry, the potential danger of dust explosion has greatly increased. Explosion proof technology can prevent explosions from spreading from the initial position to other process units, avoid "secondary" or system explosion accidents, and thus reduce explosion disasters. Reduce the risk of irreparable damage and loss in production.
The explosion-proof valve is a popular explosion-proof device internationally due to its simplicity and reliability.
Under normal operating conditions of the system, the internal back pressure valve disc floats due to airflow, and the explosion-proof valve opens; When the system is stopped, the back pressure valve disc relies on the inclined end face on the inlet side due to its own weight; If allowed, the outlet side of the explosion-proof valve experiences deflagration or explosion, and due to the increase of back pressure, the airflow flows in the opposite direction, causing the back pressure valve disc to close. The pressure wave generated by the explosion will cause the throttle blade to tightly close on the inclined end face of the inlet side, thereby preventing the explosion from spreading to the upstream pipeline and equipment, thereby preventing the occurrence of secondary explosions and protecting the safety of personnel and equipment.
