In some embodiments, the valve disc of smoke controlling valve is provided with multiple tracks crooked position, and crooked position has angle, and every sheet valve disc is all integrated, and its thickness is between 1.2-2.5mm.This design makes smoke controlling valve when closing, valve disc and valve disc overlap joint are closely, gap between valve disc and valve disc reduces, crooked position is utilized to add the rigidity of whole valve disc and ensure the straightness accuracy of blade when being out of shape extension, hinder air-flow along the leakage in lap gap direction, better improve the tightness of valve.
In some embodiments, the crooked position angle on the valve disc of smoke controlling valve is less than 90 °, but is greater than 80 °.This design makes the valve disc of smoke controlling valve can flexible rotating smoothly, plays its effect every cigarette back-fire relief during use.
In some embodiments, the valve disc of smoke controlling valve can operate in 0-90 ° of rotation according to actuator, and it runs the unlatching or the closedown that are smoke controlling valve.This design ensure that the validity of the counter measure of smoke controlling valve.
In some embodiments, the valve body both sides of smoke controlling valve are respectively equipped with air intake pipe and air outlet tube, and air intake pipe is located at the left side of valve body, and air outlet tube is located at opposite side.This design makes smoke controlling valve better play its effect every cigarette back-fire relief in use.
In some embodiments, the actuator shaft in the actuator of smoke controlling valve and sharf adopt split type convexly, recessed to take turns, and also use lever construction simultaneously.This design makes smoke controlling valve blade axle and actuator shaft when bias, and can also keep good running, valve disc can open and close flexibly, and plays power-saving function.
In some embodiments, it is movable assembled that the valve body of smoke controlling valve is connected by fastener bolt with housing vertical module by housing level module, and its plate thickness is between 1.8-3mm.This design strengthens body strength, increases work efficiency, overcomes welding deformation, for quality of product performance reliability, conformity provide guarantee.
