Description
Technical Field
The utility model relates to a fire prevention valve equipment technical field particularly, relates to a refluence exhaust fire prevention valve.
Background
The fire damper is a valve type that is closed by the temperature control of the fusible alloy, using the action of gravity and the action of a spring mechanism. The novel product also utilizes the memory alloy to generate deformation to close the valve. It has the following functions: when the temperature of the flue gas reaches 280 ℃, people are basically evacuated, the actual meaning of the flue gas discharge is not realized, and the valve is automatically closed when the fire is brought in the flue gas, so that the fire is prevented from spreading. The smoke exhaust port of the system can also be a normally closed fireproof smoke exhaust port, and a smoke exhaust fireproof valve on a branch pipe is omitted. In case of fire, the tuyere is opened by a control center through 24V direct current or manually opened, and is automatically closed when the smoke temperature reaches 280 ℃, and the reset is also manually performed. The inlet of the smoke exhaust fan room is also provided with a smoke exhaust fire prevention valve to prevent fire from spreading to the layer where the fan room is located. In order to prevent fire and toxic high-temperature smoke from spreading and expanding through the air pipe in case of fire, a fire-proof valve is required to be arranged on the air pipe of the ventilation and air-conditioning system. When the exhaust duct of kitchen, bathroom and toilet etc. is connected with vertical shaft it also must adopt correspondent measures to prevent fire from spreading between every floor along the exhaust duct. When exhaust ducts of kitchens, bathrooms, toilets and the like are connected with a vertical shaft, fire valves are arranged on branch pipes if no measures for preventing backflow exist; when there is a measure to prevent backflow, the fire valve may not be provided. The fire damper can be automatically closed when the temperature reaches 70 ℃, and the traditional fire damper used in China at present is complex in structure, high in manufacturing cost and inconvenient to install in pipelines.
