Explosion Isolation Valve

Product Overview

In reality,many containers are connected with each other,such as dust collector and pipe、food bin and pipe,once adevice explodes,the flame and air pressure will spread to other devices along with the pipe,thus causing secondary explosion or multiple explosions of the device.Equipped the explosion isolation flap valve can effectively prevent the spread of explosion,protect adjacent device or workshop which can prevent secondary explosion or multiple explosions.

A pipeline explosion isolation valve is a safety device used in industrial pipeline systems. Its main function is to prevent the reverse propagation of explosive flames and pressure within the pipeline, thereby protecting downstream equipment and personnel safety.

The following is detailed information about the pipeline explosion isolation valve:

Product Features

Efficient Explosion Isolation: It can respond to explosive pressure in an extremely short time, quickly close the valve disc, and block the propagation of the explosion.

Adaptability to Complex Working Conditions: Manufactured using high-strength materials such as stainless steel or aluminum alloy, it is resistant to high temperatures, high pressures, dust, and corrosion.

Compact Structure: Small in size and light in weight, facilitating installation and maintenance.

Intelligent Design: Some high-end products are equipped with real-time monitoring devices, enabling remote monitoring of the valve status.

Efficient Explosion Isolation

With its precise structural design and sensitive pressure-sensing mechanism, it can respond quickly and close instantly when an explosion occurs. The explosion isolation efficiency is as high as over 99%, which greatly reduces the risk of explosion spread. For example, in a flour mill, if a dust explosion occurs in the grinding workshop, the one-way explosion isolation valve can immediately cut off the pipelines connected to other workshops to prevent the fire from expanding.

Long Service Life and Reliability

It is made of high-quality materials with high strength, high temperature resistance and corrosion resistance, such as stainless steel. It can adapt to harsh industrial environments, operate stably for a long time, reduce the frequency of maintenance and replacement, and lower the enterprise's safe operation costs.

One-Way Flow Design

It only allows materials or gases to flow in a single direction without affecting the normal production process. At the same time, the valve disc remains open in the non-explosion state, ensuring unobstructed pipelines and low resistance, which will not have a significant impact on the material conveying efficiency.

Working principle

During a dust explosion, the shockwave precedes the flame front. The explosion isolation valve rapidly closes upon detecting the shockwave and is securely locked in place by its self-locking mechanism, effectively preventing the propagation of both flames and pressure waves.

After the explosion event, the valve can be manually reset. Following simple maintenance and safety evaluation, it becomes ready for reuse. During normal operation, the valve disc remains open through an assisted opening device.

Blast Sensor: HE

Use and Maintenance

It is important to ensure that the bursting valve is open before the system fan is operated to prevent damage to the fan and other equipment due to locking of the valve flap closure.

Before operating the system fan, it is necessary to ensure that the explosion-proof valve is in the open state to prevent damage to the fan and other equipment due to the valve disc being closed and locked.

After installation and use, maintenance should be carried out at least once a month, and the frequency of maintenance can be appropriately increased according to specific working conditions.

After maintenance and assembly, a sealing test should be conducted and detailed records should be made for future reference.
