There are many types of gate valves. Knife gate valves are one of them. It is also called a knife gate valve. Gate valves can be divided into slab gate valves and knife gate valves according to different types of structures. Depending on the connection method, the knife gate valve can be divided into flange type, lug type and wafer type.
Compared with ordinary gate valves, the structure of the knife gate valve is simple. Its opening and closing member is a shutter. The direction of movement of the shutter 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 mediums with higher consistency and solid particles. From the name we can see that the knife gate valve mainly relies on the blade-shaped shutter to cut the medium. The shutter has two sealing faces that form a wedge shape. The shutter can be made as a unitary rigid shutter. It can also be made into a flexible shutter that produces a small amount of deformation and improves the sealing property from the process. In summary, the knife gate valve has the following product advantages compared to the ordinary gate valve:
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 is easy to install, easy to disassemble and easy to maintain under the working condition of the dirt medium. The valve seal can be replaced without removing the valve, which makes valve maintenance easier.
3. The ram gate with the function of the knives has a good effect. It can effectively break all kinds of debris in the medium and solve the leakage phenomenon after the blockage of the block, particle and fiber media.
4. The ultra-short structural length of the knife gate valve makes it small in size, small in flow resistance, light in weight, saves material, and takes up less space.
Although the price of the knife gate valve is about 20% higher than that of the ordinary gate valve, its better performance has been widely recognized by the market, and it has quietly boarded the list of the most popular products of the Bundor company.
