An Introduction To Explosion Isolation Flap Valve

April 4, 2023 Mason Tisdall

Explosion isolation flap valves are a critical component in many industrial plants and processes. It is a safety device that is designed to protect personnel and equipment from the effects of an explosion caused by combustible dust or gas.

The valve works by creating a barrier between the hazardous area and the non-hazardous area, preventing the combustible dust or gas from entering the non-hazardous area. This helps to minimize the potential for damage to personnel and equipment.

Explosion isolation flap valves are typically made of stainless steel, aluminum, or other non-combustible materials. They are available in a variety of sizes, shapes, and configurations to meet the specific requirements of each application.

The design of the valve typically consists of two or more flaps that are hinged together and are able to move independently of each other. The flaps are designed to open and close quickly, allowing the valve to act as a barrier against the hazardous material.

The flap valve is typically mounted onto the wall of the hazardous area with a flange, or it can be installed into the floor. The flaps are controlled by either manual or automated means, depending on the application and requirements. The manual method requires a person to open and close the valve, while the automated method utilizes a solenoid or other automated control device.

Know About Explosion Isolation

Explosion protection is intended to protect personnel and surrounding machinery. Explosion isolation involves "blocking" the explosion through the pipeline process. The goal here is to stop it from traveling any further.

An explosion can continue to gain momentum and create secondary explosions and fires. Despite the release or suppression of the explosion, the dust explosion can still move backward. This is carried from the process vessel to the rest of the process zone via inlet pipes and associated equipment. You can hire professionals to install an explosion isolation valve.

You can also use explosion-proof insulation on dust collectors, process vessels, or other equipment. In this case, it is used together with the connection pipe and adhering to the installation distance to the tank.

Dust collector insulation

The dust collector holds a large amount of dust. If this combustible dust spreads into the air and ignites, the result is catastrophic, so the dust collector must be isolated. Explosion ventilation then avoids this risk.

However, in some cases, pressure waves and dangerous flames can propagate back through the connecting line. This requires the use of a blast isolation valve, also known as a non-return valve, flap valve, or barrier valve.

In the event of an explosion, the pressure surge initially forces the valve to close, blocking further distribution of the flame through the process line connecting process ductwork, thereby isolating the collector from the explosion.
