Do you know how to select 3C fire valve

 The effect of the 3C fire valve is to assemble the electronic components in the ventilation duct to provide safety protection when the duct enters the direct safe fire zone. Usually open, after overtemperature automatic off, for safety protection. The perforated plate is located inside the air duct and can not be seen from the outside. The role of the valve is in the case of fire, linkage to open the fan exhaust system or exhaust system, when the temperature exceeds the set temperature of the valve body fusible alloy steel, fusible alloy steel melt off, the valve automatically closed, prevent the fire from spreading. 1, the rotation of prefabricated components should use corrosion-resistant metal composite materials, and flexible rotation. Gate valve shell thickness can not be less than 2mm. 2. Except for the attitude temperature of the kitchen fume exhaust management system of the office building is 150 ° C, the general temperature is 70 ° C. 3. The oil passage plate blade is made of steel plate, the thickness is 2 ~ 6mm, and the oil passage plate is made of flame retardant material. 4, the efficacy of gate valves, to open or normally closed as usual, fully automatic closing and opening, manual closing and opening requirements. 5, if the gate valve and axial flow fan linkage should take with double-toggle switch machine equipment.3C fire valve installed in the air circulation and refrigeration unit ventilation and return air outlets. It's generally open. When the temperature of the gas in the pipe reaches, the fusible sheet will melt. Under the action of torsion spring, the valve will be automatically closed. In a certain time, the valve can take into account the fire safety stability and fire safety consistency requirements, and can prevent smoke and fire. The basic principle of 3C fire valve is to use the temperature control of fusible aluminum alloy profiles installed on the valve, to use the interaction force and the role of the yellowing mechanism, when the safety accident occurs, the flame invades the pipeline, high temperatures cause fusible aluminum profiles to melt on the valve, or deformation of the memory alloy causes the valve to automatically close, facilitating the use of vertical takeoff and landing and fire safety zones on site. The air sent by the centrifugal fan motor is distributed to the riser, and the dust is discharged from the riser into the exhaust fan. When there is a fire in the building, the gate valve on the 3C fire systems engineering is quickly shut off in the ventilation system to prevent the spread of the accident.
