There are many types of gate valves. Knife Gate Valve is one of them, also called a knife gate valve. According to different structure types, gate valves can be divided into flat gate valves and knife gate valves. According to the different connection methods, knife gate valves can be divided into flange types; lug type and wafer type.
1. Valve control can be used for local and remote control, and can also realize remote position display and remote centralized control according to user requirements.
2. Lightweight: The body is made of carbon steel, and the weight is about 20%-30% lighter than the traditional gate valve. It is easy to install and maintain.
3. The use of this valve can improve the closing and sealing performance of the conveying pipeline system, prevent leakage to the maximum extent, and play a positive role in improving production efficiency and protecting the environment.
4. The sealing surface is made of highly wear-resistant and corrosion-resistant ceramic materials, and adopts inlay technology, which has high corrosion resistance and good wear resistance, so that the valve has a long life and the cost performance is 10 times higher than that of ordinary valves.
Knife Gate Valve
Compared with ordinary gate valves, the structure of the knife gate valve is simple, the opening and closing part is a gate, and the movement direction of the gate is perpendicular to the direction of the fluid. It is small in size, flexible in operation, and easy to install. It is more suitable for a medium with higher consistency and solid particles. As we can see from the name, the knife gate valve mainly relies on the knife-edge gate to cut off the medium. The gate has two sealing surfaces, forming a wedge shape. The gate can be made into an integral rigid gate; it can also be made into an elastic gate that can produce slight deformation and improve the sealing performance from the process. In summary, Knife Gate Valve China has the following product advantages compared with ordinary gate valves:
1. The U-shaped gasket has a good sealing effect.
2. The full-diameter design makes the medium passability strong. At the same time, it can be easily installed, easily disassembled, and maintained under the working condition of dirty media, and the valve seal can be replaced without removing the valve, making the valve maintenance easier.
3. The gate with knife function has a good gate braking effect, can effectively stop all kinds of debris in the medium, and solve the leakage phenomenon of the medium containing block, particle, and fiber after it is broken.
4. The knife gate valve has an ultra-short structure length, small size, small flow resistance, lightweight, material saving, and small effective space.
