[Tianjin Jin Zhongji HVAC purification equipment to recommend the star product - plate discharges] scope mounted on the front walkway or smoke chamber, 280 degrees exhaust damper, smoke-free exhaust system of the window of the room mouth, can be mounted on a ceiling or mounted on the side wall. Features 1, usually normally closed, the control center DC24V electrical signal, fast open exhaust port. 2, long-distance manually open. 3, long-distance manually reset. 4, the output signal of the opening action, interlocking related equipment. 5, does not have a rear plate discharges the flue gas temperature of 280 degrees to open the re-closing function. 1, the event of fire frame (housing), the blades should be able to prevent deformation failure, 70 degrees normally open damper, its plate thickness not less than 2mm. 2, the fusible element should fire department recognized standard product, its melting temperature should meet the design requirements. 3, the valve action should be reliable, should shut tight, which allows air leakage should comply with the relevant regulations. [Tianjin Jin Zhongji HVAC purification equipment to recommend the star product - fire control valve] material: carbon material, galvanized plate installed in the ventilation and air conditioning system, the return air duct, normally closed damper, usually in an open state, the pipeline fires when the flue gas temperature reaches 70 degrees off, and in a certain amount of time to meet leakage of smoke and fire integrity requirements, since the role of smoke fire retardant. (1) The valve usually is always on when the airflow temperature reaches 70 ℃, the temperature sensor operation, the valve is closed; (2) within the range of 0 ° ~ 90 ° manually adjust the vane opening degree; (3) manually shut down or manual reset ; (4) the output valve closes signal can be interlocked with other fire-fighting equipment. Advantages: 1, low air leakage, airtight performance .2, strong corrosion resistance, Tianjin damper, long service life. 3. Actuated flexible. Feedback, interlock signal accurate. The main functions and characteristics 1, manual open, manual reset closed. 2, the output signal and valve interlock control signal is turned on. 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. 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. For horizontal or vertical airflow duct. 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. 70 degrees _ normally open damper in the base (online consultation) _ Tianjin Tianjin Jin Zhongji damper provided by HVAC purification equipment.
