Entering the country from the eighties. In less than two years time, the use of common areas ranging from extended to a broader industries. Coal mines from the plant, discharge refuse, slag. The development of the city's sewage treatment, the development of industrial pipes from the general to the food, health, medicine, and other professional piping systems. Slim knife gate valve with its small size, low flow resistance, light weight, easy to install, easy to disassemble, etc. solve the ordinary valve, flat gate valve, ball valves, globe valves, control valves, butterfly valves and other types of flow resistance , heavy, difficult to install, large area, such as the difficult problems. After the knife gate there, a lot of generic classes off valves and regulating valves have been the replaced. Today, the world's largest amount of knife gate valve is the United States and Japan. Electric knife gate valve, electric knife gate valve knife gate valve knife gate valve American Standard Precautions product and its characteristics: Knife gate valve opening and closing parts is, the direction of movement of the fluid direction perpendicular to the gate, knife gate can only be fully open and fully closed, can not be adjusted and the throttle. Ram has two sealing surfaces, the two most common mode of sealing surface to form a wedge gate valve, wedge angle with the valve parameters vary, usually 50, wedge type knife gate valve can be made of a whole, called rigid gate; when it can be made to produce micro deformation gate, in order to improve its process, make up the sealing surface angle deviation generated in the process, this gate is called the flexible gate knife gate valve is closed, the sealing surface You can only rely on media pressure to seal, that will depend on the sealing surface of the medium pressure ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. most of knife gate valve is sealed by force, that is When the valve is closed, to rely on external pressure to force the gate valve to ensure tightness of the sealing surface.
