Inlet knife gate valve is a common type of valve, which is mainly used to cut off or turn on the medium. Its name ** is derived from the shape of the valve plate (ram), which is similar to a blade, so it is named imported knife type gate valve.
The structure of the imported knife gate valve is mainly composed of the valve body, valve, sealing ring, suspension device, handle, etc. This kind of valve is characterized by simple structure, small size, light weight, good sealing, corrosion resistance, flexible operation, etc.
Imported knife gate valves have a wide range of applications in various industrial fields, such as mining, metallurgy, chemical industry, sewage treatment, etc. It is particularly suitable for the conveying of media such as highly concentrated solid particles, dusts and particulate impurities, as it has a knife-type bevel cut at the bottom of the valve plate, which can easily pass through the solid particles in the pipe.
The operation mode of the imported knife gate valve is usually manual operation, but it can also be controlled by electric, pneumatic, hydraulic and other methods. It has a wide range of applications and can be used to control various media such as slurry, sewage, oil, natural gas, chemicals, etc.
The parameters of imported knife gate valve mainly include diameter, pressure level, material, connection method, etc.
Caliber: The caliber of the inlet knife gate valve refers to the opening diameter of the valve, usually in inches (inch). Different diameters of imported knife gate valves are suitable for different pipe sizes, the common calibers are DN50, DN80, DN100, etc., where DN represents the nominal diameter.
Pressure Rating: The pressure rating of the inlet knife gate valve refers to the maximum pressure that the valve can withstand. Different inlet knife gate valves have different pressure ratings, such as PN10, PN16, etc.
Material: The material of imported knife gate valve is usually carbon steel, stainless steel, etc. Depending on the media and operating conditions, different materials can be selected.
Connection: The connection methods of imported knife gate valve include welding, flange connection, etc. According to different pipe connection needs, different connection methods can be selected.
The imported knife gate valve has the following significant advantages:
Simple structure: The structure of the imported knife gate valve is relatively simple and consists of fewer parts, making it relatively easy to manufacture, install and maintain. This also helps to reduce breakdowns and repair costs.
Quick shut-off capability: The blade structure of the imported knife gate valve enables it to quickly cut off the medium. When a quick shutdown of the piping system or emergency repairs are required, the inlet knife gate valve responds quickly and cuts off the flow of media.
Strong wear resistance: The blades and seats of imported knife gate valves are usually made of wear-resistant materials, which have good wear resistance. This makes the inlet knife gate valve more reliable when handling media containing particulate matter, reducing wear and leakage issues.
High temperature and high pressure application: Compared with some other valve types, the imported knife gate valve has better adaptability under high temperature and high pressure medium. Due to the large contact area between the blade and the valve seat, the imported knife gate valve can withstand high operating temperatures and pressures.
High reliability: The inlet knife gate valve is usually only fully open and completely closed in the working state, and does not require frequent adjustment and operation. This makes the imported knife gate valve relatively stable and reliable, and it is not easy to fail or leak.
Low fluid resistance: When the fluid passes through the inlet knife gate valve, the flow resistance is small and the flow rate is large, which can save energy.
Reliable sealing: The imported knife gate valve has good sealing performance and can effectively prevent medium leakage.
Good elastic memory: The imported knife gate valve has good elastic memory, which can adapt to various working conditions and maintain good sealing performance.
Long service life: The imported knife gate valve has a long service life and can operate stably for a long time to ensure the continuity and stability of the production process.
