Stainless steel knife gate valve profile knife gate valve open and close the component for the door, perpendicular to the direction of the fluid flow in the direction of the door, knife gate valve can only be fully open and fully closed, can't adjust and throttling. Plunger has two seal face, gate wedge formed two of the most common way of sealing surface and the parameters of the Industrial Valves, usually in the form of 50 wedge Angle, the wedge knife gate valve can be made into a whole, is called a rigid gate; When can make it generates trace of deformation of ram, in order to improve its technology, made up for in the machining process of sealing surface Angle deviation, the gate is called elastic disc type knife gate valve is closed, sealing surface can only rely on medium pressure to seal, which is dependent on the media pressure will ram pressure to the other side of the valve seat sealing surface, to ensure that the seal, this is the sealing surface of the seal. Most of the knife gate valve sealed by force, that is, when the valve is closed, the shutter will be forced to rely on the external pressure of the seat, to ensure the sealing surface of the seal. Stainless steel knife gate valve/overview of 1. Short the length of the structure, material saving, can greatly reduce the total weight of the piping system. Stainless steel knife gate valve/in the media just as its name implies is to take the board with knife oblique incision knife gate valve on the bottom of the valve plate, has the function of cutting medium piece of closed Industrial Valves from media. This valve is typically used for opening and closing the pulp, ash content, chemicals, sewage, food and other media flow. Usually the pressure range of 1. The use of 6 mpa, using the general under 120 ℃ high temperature can also be used, instead of using the special material. Sealing performance requirements, can be divided into soft seal and hard seal. According to the rank and inspection soft seal can achieve zero leakage hard seal leakage. The valve is easy to operate, free and open, flexible and reliable bill; Simple maintenance valve components and sealing structure is reasonable, convenient and practical seal replacement. 2. Little room for the effective, and can effectively support the strength of the pipe, tube can reduce the possibility of vibration. 3. Shutter austenitic stainless steel, corrosion resistance is greatly increased, the choice can effectively prevent corrosion by the shutter seal leakage of diarrhea. Adopt soft packing 4. Ptfe sealing is reliable and flexible operation of the light. 5 knife gate valve has a feature, which can effectively remove the media of all sorts of sundry.
