Description
Technical Field
The invention belongs to the technical field of fire valves, and particularly relates to a novel fire valve external temperature sensing device.
Background
The fire-proof valve is arranged in the middle or the tail end of a ventilating pipeline which passes through the fire-proof subarea in a ventilation air-conditioning system of a building, the fire-proof valve is in an opening state under the normal operation working condition, the valve is closed under the fire working condition, a fire area is isolated from a pipe network, and the functions of smoke isolation, fire resistance and fire spread control are achieved.
The typical structure of the fire-proof valve comprises a valve body arranged on the ventilation pipeline, a blade, an actuating mechanism driving the blade to rotate so as to control the valve to close and open, and an internal temperature sensing device arranged in the valve body. When the temperature of the flue gas in the pipeline exceeds the fusing temperature set by the temperature sensing device, the internal temperature sensing device fuses to act, and sends a signal to the actuating mechanism or directly drives the actuating mechanism to act, so that the blades are driven to rotate to close the valve.
In view of the fact that the fire damper adopts the internal temperature sensing device, when a fire disaster occurs, the fire disaster can be prevented from spreading to other fire-proof subareas through the ventilation pipeline in the building, nuclear power engineering, tunnel engineering and the like cannot be met, and the requirement of closing the fire damper valve needs to be controlled by sensing the change of external temperature at first when the fire disaster occurs at the initial stage. However, the internal temperature sensing device cannot be externally mounted to achieve the same function due to the limitation of the internal structure.
The chinese patent publication No. CN103335164B discloses a fire damper and an external temperature sensing device thereof, which includes a fixing member for fixedly connecting with a housing of an actuator; the movable part is used for triggering the actuating mechanism to act so as to close the valve; the elastic element is arranged between the fixed piece and the movable piece; one end of the fusing part is fixedly connected with the fixed part, and the other end of the fusing part is fixedly connected with the movable part, so that the elastic element is in an energy storage state. When the external temperature of the fire-proof valve reaches the allowable fusing limit value of the fusing part, the fusing part is broken, the elastic element releases energy, and the movable part moves to a manual action deflector rod for starting the actuating mechanism relative to the fixed part under the action of the elastic force of the elastic element, so that the actuating mechanism acts to drive the fire-proof valve to close. However, in the actual production process, it is found that since the fuse link is fixed to the movable member and the fixed member by bolts, the assembly is very inconvenient, and not only is it difficult to improve the processing efficiency, but also the production cost is increased.
