one way check butterfly damper valve is used for the ventilation duct of flue gas and other gases. Its main function is to prevent the backflow of the medium. The function of the check valve is to allow the medium to flow in only one direction and prevent the flow in the opposite direction. Usually, this valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the fluid pressure and the self weight of the valve disc act on the valve seat, so as to cut off the flow.
three-lever type damper butterfly valve
The three-lever type damper butterfly valve mainly composed of valve body, valve disc and transmission part; The opening and closing of the valve is achieved by the transmission device through the valve rod rotating lever to loosen the spring, and then through the locking device; After the valve is closed, the handle of the rotating device must be locked to ensure sealing. On the contrary, when it is opened, the locking state must be released.
It is mainly used to regulate and control the flow of air, smoke, dust and flammable gas in the process pipe.
