Three-eccentric Center Butterfly Valve
Product introduction:
The shaft center of the valve stem deviates from the center of the disc and the center of the body at the same time, and the axis of rotation of the valve seat and the axis of the valve body channel have a certain angle, which is called a triple eccentric butterfly valve.
Features:
The triple eccentric butterfly valve is widely used in industrial pipelines such as metallurgy, electric power, petrochemical industry, water supply and drainage and municipal construction where the medium temperature is ≤425°C, for flow regulation and fluid load-off. Material: cast iron, cast steel, stainless steel.
Structural Principles：
The sealing between the sealing surface of the valve plate and the valve seat is to press the plate against the valve seat by the torque of the transmission device. In the positive flow state, the higher the medium pressure, the tighter the seal squeezes. When the flow channel medium flows back and the medium pressure rises, the unit positive pressure between the valve plate and the valve seat of the triple eccentric butterfly valve becomes lower than the medium pressure, and the seal begins to leak.
