2, is closed to test the reliability of multi-leaf delivery outlet fire: temperature sensor action, leafy outlet should be automatically and reliably closed. Reliable closed include: leafy outlet automatically turns off; the gap between multi-leaf delivery outlet vane or between flaps and no more than 2mm. Now we know how to detect leafy outlet The quality of the bar, leafy outlet quality related to future results. We can according to two aspects mentioned above is carried out in the purchase, choose the right product. My company has many years of production and marketing experience, the products meet the design specifications, the performance of your table usually was normally closed, smoke is sent to the control center via the electrical signal (DC24V) In case of fire, the solenoid is energized actions performed within the organization, the valve automatically turn on and turn on the electrical signal output. PYK-DY remote valves can be opened manually. After the manual reset valve operation (PYK-DY type of remote manual reset). Technical parameters air volume (pressure 300Pa): ≤700m3 / m2.h control voltage: DC24V Micro Switch contact capacity: AC 380V 3A when full drag coefficient: <0.5 fuse action temperature: 280 ℃ structure of the main components: a valve body, valve leaves, shafts, bushings, inspection port, the actuator maximum production size 800 * 800 (WXH) PYK-DY-type wire rope with a length of not more than 6 m range: Press gbj45-82 exhaust port installed in the aisle, smoke before the room and the exhaust system of the room with no windows, Anqing remote control multi-leaf smoke vents, smoke outlet mounted on the front of the room and the elevator walkway, usually in a normally closed state. Outlet exhaust port with the same form factor, Anqing fire leafy exhaust port, install the form of vertical and horizontal considerations usually NC NC leafy outlet installation, electric, manual opening. Output on the start signal. Manual reset closed. 280 ℃ temperature sensor operation, Anqing electric leafy exhaust port, the valve is closed again. The use of thin body, reduce operating box size, increase the effective area of ??the ventilation exhaust. Other notes major components: body, valve, bushing, thin executive body, grille panel. b size ≥800 when assembling two actuators. Size a × b × l Rectangular: 400 × 400 × 150 ~ 2000 × 1250 × 150 NC leafy outlet is a commonly used air-conditioning system, an important device, commonly used in the building of multi-leaf aisle electric outlet wholesale, stairs antechamber, Huaiyuan leafy exhaust port, exhaust pipes, engine room entrance and so on. Leafy outlet for fire safety building has a very important role, so I chose to be detected when its quality. 1, the test normally closed outlet shut leafy reliability: leafy outlet 10 closed operations, should be able to close the open position flexible and reliable, all parts should be no significant deformation, wear and other influences sealing performance damage. Linquan multi-leaf smoke vents, Shia ventilation equipment, Anqing galvanized sheet provided by the multi-leaf smoke vents Air Conditioning Equipment Co., Ltd. Shandong GREAT fan. Linquan multi-leaf smoke vents, Shia ventilation equipment, Anqing galvanized sheet multi-leaf smoke vents Shandong GREAT Fan Air Conditioning Equipment Co.
