Electric sealed off valve performance and multi-leaf structure: (1) Structure: electric sealed off valve is the basis of multi-leaf valve on the valve closed manually adjust the handle to manipulate ZAJ-2 electric actuator manipulation electric control valve closed price manipulation by the Executive Motor Linkage opening angle of the blade to control air flow. ZAJ-2-type electric actuator stroke angle of rotation with a flat gear reducer leafy off valve price, through a set of gear to make a reversible motor came from a high-speed, low torque into a low-speed, high transfer moments, while taking advantage of dew outside the actuator coupled to the output shaft of the switching valve seat on the blade shaft associated company, in order to achieve electrical, mechanical linkage. When pressed by hand so that gear is disengaged, anywhere you can adjust the angle of pull, so that the angle of the control valve to work as needed. According to the actual needs, adjust the seat position switch before connecting valve work must correspond with the observation hole location. Product Name: smoke fire control valve function · 70 ℃ temperature sensor operation, the valve automatically closes. · 280 ℃ temperature sensor operation, the valve automatically closes. · Manually shut down; manual reset open. · Manually adjusting the blade angle. (Five-speed adjustment). · Output signal or interlock control valve closed signal. · Amount of air leakage: the national standard (see test report). · Refractory time: ≥90min. · Corrosion resistance and reliability are in line with the national movement.
