stainless steel knife gate valve adopt knife switches, shear effect is good, the most suitable for mud, such as powder, fiber is not controllable fluid. Widely used in papermaking, petrochemical, mining, water drainage, food and other industries. It has a variety of seats to choose from, and can request according to the on-site control equipped with electric or pneumatic actuators, realize the automatic operation of the valve. Stainless steel knife gate valve is widely used due to its own characteristics. One is the sealing effect is good, U gasket has good elasticity; Second, the diameter design, passing ability; Three is the braking effect is good, can effectively solve the brake block, particles, fiber media after the leakage phenomenon; Third, good braking effect, can effectively solve the brake after leakage phenomenon; Fourth, has good tightness and elasticity. Good sealing effect. Because maintenance is convenient, without removal of valve replacement valve seals. Imports of stainless steel knife gate valve opening and closing parts for the gate. The direction of flow direction and the vertical of the gate. Import knife gate valve can only be fully open close, can't adjust and throttling. Remind you when using stainless steel knife gate valve, valve has two sealing surface, the two most commonly used way is to put the gate seal face into a wedge, the wedge Angle changes over the valve parameters, usually in the form of 50, wedge knife gate valve can be made into a whole, known as the rigid gate; Can can can produce slight deformation of the gate. In order to improve the manufacturability, make up for the sealing surface Angle deviation caused by the machining process, the gate is called the resilient gate. When stainless steel knife gate valve is closed, sealing surface can only use medium pressure seal, with medium pressure to press the sealing surface of the gate to the other side of the seat, to ensure the sealing surface is sealed. Most knife gate valve is forced to seal, namely when the valve is closed, must use outside the gate is forced into the seat, to ensure the sealing surface.
