Description

Explosion-proof pressure-proof fire-proof valve Technical Field The utility model relates to the technical field of fire valves, in particular to an explosion-proof pressure-proof fire valve. Background An explosion-proof pressure-proof fire-proof valve is a safety device for preventing accidents in a pipeline system under fire, explosion or high-pressure environment. Is generally applied to dangerous environments such as industrial facilities, chemical factories, petrochemical industry, gas stations and the like. These valves are designed to be material and structure selected based on the pressure rating, temperature range and fire protection requirements of the pipe, thereby ensuring safe operation under extreme conditions. Fire protection valves typically employ a trigger mechanism to control the opening and closing of a gate, and when a fire occurs in a ductwork, the fire will trigger the closing mechanism of the fire protection valve via a sensor or a thermal sensing device. With the rise of temperature, the triggering device can be fused or activated at a certain temperature, so that the valve is automatically closed. The process can rapidly cut off the spreading path of the fire source at the initial stage of the fire, and effectively prevent the fire from spreading to other areas, thereby reducing the loss of the fire and protecting the safety of the whole pipeline system. Such conventional fire damper systems, while capable of responding quickly in the event of a fire, have certain limitations. Because the triggering device is triggered by fusing or mechanical action, once a fire is extinguished, the trigger device is damaged and must be replaced in time to restore the normal function of the system.
