Jiangsu JFHT fire control valve

 Jiangsu JFHT fire control valve when the valve is closed, the output shutdown signal, installed in the ventilation and air conditioning system, the air return duct, usually was turned on, when the fire shut down the pipeline when the flue gas temperature reaches 70 degrees, and in some time to meet the leakage amount of smoke and fire integrity requirements, since the role of smoke fire retardant. Smoke fire control valve is usually installed in the need to adjust the amount of wind power or signals need control valve closes the duct ventilation and air conditioning systems. Small fire control valve is usually installed in the ventilation duct area is small, compact space ventilation and air conditioning systems for horizontal or vertical airflow duct, for horizontal or vertical airflow duct. Usually in a normally open valve, when the airflow temperature reaches 70 ℃, the temperature sensor operation, the valve closes, fire control valve is usually installed on the need to adjust the air flow duct ventilation and air conditioning systems for horizontal or vertical airflow duct. Jiangsu JFHT fire control valve installed in the ventilation, air conditioning system, the return air duct on the road, usually was turned on, when the gas pipeline fire when the temperature reached 70 ℃, fusible film fuse, the valve automatically closes under the force of the torsion spring within a certain period of time to meet the fire resistance stability and fire integrity requirements, from smoke fire retardant valves.
