Full analysis of knife gate valve characteristics: from structure to application
Wafer knife gate valve is a kind of valve that controls the flow of the medium by the lift of the gate plate. It is widely used in the industrial field because of its simple structure, small size, light weight and good sealing.
1. Structure and working principle
Knife gate valve through the lifting of knife gate to cut off or adjust the flow of the medium, its structure is simple, the opening and closing mechanism is the gate, the direction of movement is perpendicular to the fluid.
2. Application field
Knife gate valve is suitable for industrial pipeline, municipal construction, water conservancy engineering, metallurgy, petroleum, chemical, electric power and pharmaceutical industries, suitable for water, oil, gas, steam and acid and alkali liquid and other media. For high viscosity media and media containing particulate matter, special attention should be paid to the use of knife gate valves, because these media may cause the gate to stick.
3. The difference between knife gate valve and ordinary gate valve
The main difference of knife gate valve is that its structure is simple, suitable for high consistency medium and solid particles, relying on knife gate to cut off the medium.
Outstanding advantages:
Full diameter design, so that the medium through the strong capacity. At the same time, it can be easy to install, easy to disassemble and easy to maintain under the working condition of dirt medium. The valve seal can be replaced without removing the valve, making the valve maintenance simpler.
The gate plate with knife function has good breaking effect, can effectively remove all kinds of debris in the breaking medium, and solve the leakage phenomenon after the breaking of the block, particle and fiber medium.
Knife gate valve ultra-short structural length, small volume, small flow resistance, light weight, material saving, occupy a small effective space
