Principle of Explosion proof Device (Pipeline Explosion proof Valve) for Dust Removal System:

Under normal operating conditions of the system, the internal back pressure valve disc is affected by pipeline airflow andspringUnder the action of force, it floats up and the explosion-proof valve opens. When the system is stopped, it remains in the open state under the action of the back pressure valve disc spring force. 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.

Application fields:

Production workshops for artificial boards, wood, and furniture.

Fibers, shavings, and dust generated by objects such as metals and sand in the process.

The spark environment generated during the operation of high load equipment.

Enterprises that generate high dust environments such as tobacco, food, feed, leather, etc.

Nowadays, environmental inspections are becoming increasingly strict, and the installation of explosion-proof valves is also a mandatory requirement for many enterprises. Due to the increasing demand, many enterprises disregard quality and only strive for itpriceOnly installing security checks is enough, but have you considered the anti riot capability of the product? There are many thick explosion-proof valves on the market now, but their anti explosion ability is very poor. Of course, their price is advantageous. The explosion-proof valve produced by Century Xing is four thick, and only when the thickness is reached can its anti explosion ability meet the standard. So for enterprisessafetyWe must strictly control our products. We can't just deal with inspections from security departments. But to truly consider the safety of the enterprise.

Characteristics of explosion-proof device (pipeline explosion-proof valve) for dust removal system:

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:
Unidirectional 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 after 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.

Notes:

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.
