Explosion proof valve for pipeline dust collector

Product Features:Explosion proof valve for pipeline dust collector

1. Material: Carbon steel or stainless steel, in accordance with national standards.

2. Size range: DN100-DN1000

3. Mechanical isolation equipment that does not require electrical or triggering systems

4. Low maintenance cost under pressure loss, 5. Easy to install with self-locking device, safe and reliable

Under normal operation, the self balancing device of the baffle cylinder remains open. When it occurs, due to the effect of airflow, the baffle automatically closes and remains closed under the action of the self-locking device. Therefore, it prevents transmission to other parts of the equipment or production processes.

With the development of modern industry, the potential danger of dust has greatly increased. Explosion proof technology can prevent the spread from the initial position to other process units, avoid secondary or system accidents, and thus reduce disasters. Explosion proof valve is a popular explosion-proof device that is simple and reliable. Utilize the pressure generated to push the moving valve core to block flames and pressure. Commonly used for explosion-proof isolation of trace dust transportation and clean air outlet side of dust collectors.Explosion proof valve for pipeline dust collector

Explosion proof valves can be equipped with flanges. Click on Shandong Tiancheng customer service for details before design.

This device is an economical and practical passive dust explosion-proof device, which is widely used now. It is mainly designed for use at the inlet of the protected equipment (dust collector, silo, etc.) when dust occurs in the protected equipment. Prevent the propagation of pressure waves and flames generated by dust inside the protected equipment along the connected pipelines, and avoid destructive occurrences caused by the propagation of flames and pressure waves inside the connected pipelines or to indoor buildings or other equipment.

With the development of modern industry, the potential danger of dust has greatly increased. Explosion proof technology can prevent the spread from the initial position to other process units, avoid secondary or system accidents, and thus reduce disasters. Explosion proof valve is a popular explosion-proof device due to its simplicity and reliability. Its principle is to use the pressure generated during operation to push the valve core to move and block flames and pressure. It is commonly used for explosion-proof isolation of trace dust transportation and clean air outlet side of dust collectors.

The existing explosion-proof valves mainly achieve pressure control through the movement of the valve core, which generates a huge shock wave when it occurs. The valve core is easily damaged by the shock wave, resulting in explosion-proof failure and low reliability.

The purpose of this article is to provide a unidirectional airflow explosion-proof valve to address the problem of low explosion-proof reliability caused by the easy damage of the valve core in existing explosion-proof valvesThe manufacturing method of one-way explosion-proof valve

The technical solution adopted is as follows: a unidirectional explosion-proof valve for air flow, comprising a cylindrical valve body and flanges located at both ends of the valve body and used for connecting with pipelines. The valve body is horizontally provided with a movable rod, and a switch assembly is connected to the movable rod to form and close the air flow channel. The switch assembly is at least 2 sets; The switch component comprises an upper movable plate and a lower movable plate hinged to the inner wall of the valve body, a blocking ring vertically fixed to the inner wall of the valve body and limiting the upper movable plate and the lower movable plate, wherein a sealing ring is bonded to one side of the blocking ring near the upper movable plate and the lower movable plate, and the side of the upper movable plate and the lower movable plate near the air inlet end is connected to the movable rod through a spring. When the upper movable plate and the lower movable plate are subjected to the action of air flow on one side of the spring, they rotate in the direction away from the blocking ring to form an air flow channel in the valve body. The end of the upper movable plate and the lower movable plate near the movable rod is provided with an arc-shaped groove to vertically connect the upper movable plate and the lower movable plate to close the air flow channel. Form a through hole that matches with the movable pole; The movable rod is vertically fixed downwards at the end of the airflow inlet end with an induction rod, and a baffle is provided on the inner wall of the valve body between the blocking ring and the airflow inlet end to restrict the movement of the induction rod towards the airflow outlet end.
