Dust Removal Valve
Structural features and uses
This valve is composed of valve seat, cone, valve cover, valve stem, weight, limiter and other parts. The valve stem is a lever mechanism. The valve is opened and closed by the rise and fall of the valve stem, and the sealing surface is matched by the gravity of the weight. Due to the addition of the limit adjustment device, the conical valve cover has repeated positioning accuracy and reliable sealing, which is suitable for the venting system of blast furnace and hot blast stove system.
