There are many types of one-way explosion-proof valves, which use the function of one-way valves to isolate the explosion point. As the name suggests, a modern one-way explosion-proof valve is a type of valve that functions to isolate explosive use. It is used on the inlet pipeline of dust collectors or cyclone separators, and is a simple, economical and reliable explosion-proof product. It is mainly used to block the flames and shock waves generated by internal explosions of equipment from transmitting to upstream pipelines and equipment.

Unidirectional explosion-proof valve pipeline explosion-proof valve product features:

Unidirectional explosion-proof valve is 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 flames and shock waves generated by internal explosions 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.

The installation method of one-way explosion-proof valve: horizontal installation, flange connection.

Installation location: The explosion-proof valve is about 2-7 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.

During construction, it should be noted that the dust removal pipeline should be purged of accumulated dust before installing the explosion-proof valve, and the pipeline should be cut according to the size of the explosion-proof valve. Use auxiliary equipment such as cranes for installation, and fix the bracket of the explosion-proof valve.

Preparation before construction of one-way explosion-proof valve pipeline explosion-proof valve by the construction party:

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 2-7 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.
