Knife Gate Valves
Introduction:
Knife gate valve has a wide range of applications, from coal preparation, gangue discharge and slag discharge in mines and power plants to urban sewage treatment; From slurry transportation in cement and paper mills to professional pipelines for food, health and medicine. The ultra-thin knife gate valve, with its advantages of small volume, light weight, small flow resistance, no slag accumulation, easy installation and disassembly, completely solves the difficult problems such as large flow resistance, space occupation, slag accumulation, difficult installation and maintenance of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves, etc. Therefore, a large number of universal shut-off valves and regulating valves have been replaced by knife gate valves.
The tooth shape of the knife gate valve is circular arc, and it is generally conical, like an umbrella, so it is called bevel gear. Bevel gear has high transmission efficiency, stable transmission ratio, large arc overlap coefficient, high bearing capacity, smooth transmission, reliable operation, compact structure, energy saving, material saving, space saving, wear resistance, long service life and low noise.
