Technical features of knife gate valve and precautions in use

Technical features of knife gate valve (Fengquan) and precautions in use: the opening and closing parts of knife gate valve are the gate, the movement direction of the gate is perpendicular to the direction of the fluid, and the knife gate valve can only be fully opened and closed, not be adjusted and throttled The ram has two sealing surfaces The wedge and wedge angle formed by the two sealing surfaces of the commonly used model of Zui gate valve vary with the valve parameters, usually 50 The wedge-shaped knife gate valve RAM can be made into a whole, which is called a rigid ram It can also be made into a ram that can produce slight deformation, so as to improve its processability and make up for the deviation caused by the angle of the sealing surface in the processing This kind of gate When the plate is called elastic ram knife gate valve closed, the sealing surface can only be sealed by the medium pressure, that is to say, the sealing surface of the ram is pressed to the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self sealing Most knife gate valves adopt forced sealing, that is to say, when the valve is closed, the gate shall be forced against the valve seat by external force to ensure the sealing of the sealing surface Because knife gate valve adopts knife gate valve, it has good shearing effect Zui is suitable for the fluid which is difficult to control, such as pulp, powder, fiber, etc it is widely used in papermaking, petrochemical, mining, drainage, food and other industries It has a variety of valve seats to choose from, and can be equipped with electric or pneumatic actuators according to the needs of field control to realize the automatic operation of the valve Material: cast iron, carbon steel, stainless steel size range: DN50 ～ dn600zui large pressure: 1.0MPa knife gate valve has good shearing effect due to the use of knife gate valve Zui is suitable for slurry, powder, fiber and other uncontrollable fluids, widely used in papermaking, petrochemical, mining, drainage, food and other industries It has a variety of valve seats to choose from, and can be equipped with electric or pneumatic actuators according to the needs of field control to realize the automatic operation of the valve Material: cast iron, carbon steel, stainless steel size range: DN50 ～ dn600zui large pressure: 1.0MPa provided by Wenzhou Fengquan valve
