Explosion proof valves applied to pipelines can prevent the spread of explosions, avoid secondary explosions, and thus reduce explosion disasters. To reduce the risk of irreversible damage and loss in production, explosion-proof valves are a required explosion-proof device in safety supervision due to their simplicity and reliability.

Dust explosion-proof and pressure relief products: dust explosion-proof valve, flameless release device, one-way explosion-proof valve, explosion explosion-proof valve, spark detection and extinguishing device, etc.

Features:
1. Wide applicability
2. Self locking device, adjustable by balance hammer, slight pressure loss
3. The product adopts an anti explosion design with integrated sensors for monitoring, providing millisecond level response
4. Low maintenance cost
5. Applied to the inlet pipe of dust collectors, cyclone separators, and other dust process pipelines
6. The valve disc is designed to be normally open

Principle:
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.

A large number of spot pipeline explosion-proof valves DN400 explosion-proof valve application fields:
Production workshops for artificial boards, wood, and furniture.
The environment of fibers, shavings, and dust generated during the movement of objects such as metals and sand.
The spark environment generated during the operation of high load equipment.
Enterprises that generate high dust environments such as tobacco, chemical, textile, food, feed, metallurgy, leather, rubber processing, etc.

In the production and processing of many factories, there are often processes such as grinding, polishing, electroplating, etc. These processes produce a large amount of metal dust during the operation. In order to collect and process this dust, we use dust removal systems to collect and treat the dust. Due to the prolonged lack of cleaning and maintenance by the staff during the use of the dust removal system, a large amount of metal dust accumulates inside the system. When workshop workers are working, a large amount of high-temperature particles are generated, combined with various factors, leading to a series of explosions in the dust removal system and workshop, causing huge losses to personal safety and property. In reality, many containers are connected together, such as dust collectors and pipelines, silos and pipelines. Once a certain equipment explodes, flames and air pressure will spread to other equipment through the pipeline, causing secondary or multiple explosions of the equipment. Therefore, adding explosion-proof valves can effectively prevent the spread of explosions, protect adjacent equipment or workshops, and avoid secondary or multiple explosions. The explosion-proof valve is installed on the dust removal pipeline. The function of the explosion-proof valve is to prevent the dust collector from exploding and returning to the workshop through the dust removal pipeline. This is a one-way explosion-proof valve.

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.

A large number of spot pipeline explosion-proof valves DN400 explosion-proof valve precautions:
Before installing the explosion-proof valve, the dust removal pipeline should be purged of accumulated dust, and the pipeline should be cut according to the size measurement of the explosion-proof valve. Use auxiliary equipment such as cranes for installation, and fix the bracket of the explosion-proof valve.
Preparation by the construction party before construction:
1. Prepare construction tools: plasma cutting machine, polishing machine, pliers, wrench, screwdriver, inflatable drill, hand drill, etc.
2. Prepare the high-altitude homework rope, hat, and gloves.
3. Provide construction personnel with work certificates.
4. Renting scaffolding and cranes.
5. Measure the average wind speed of three dust removal pipelines and record it. Installation location: The explosion-proof valve is about 3-4 meters away from the dust removal equipment.

Installing explosion-proof valves can effectively prevent the spread of explosions, protect adjacent workshops or equipment, and avoid secondary or multiple explosions.
Our main products include one-way explosion-proof valves, flameless venting devices, pipeline spark detectors, and other security products. We can provide installation and technical consultation.
