Knife gate valve, also known as knife gate valve and knife gate valve, is suitable for pipelines with suspended particles, fibrous materials, pulp, sewage, coal slurry, ash and slag cement mixture and other media. Cut off these media. There is actually no chamber in the valve body, the gate rises and falls in the side guide groove, and is pressed against the valve seat by the lugs at the bottom. an O-ring sealing valve seat can be used to achieve Two-way sealing If a higher medium sealing performance is required, it is divided into manual knife gate valve, pneumatic knife gate valve and electric knife gate valve. Knife gate valve is light and flexible in operation, small in size, smooth in passage, small in flow resistance, light in weight, easy to install and disassemble, nominal size DN50~DN800, can work normally under the condition of working pressure 0.6MPa~1.6MPa and operating temperature ≤100℃ Work. The gate of the knife gate valve has a shearing function, which can scrape off the adhesive on the sealing surface and automatically remove the sundries. Stainless steel gates prevent seal leakage caused by corrosion.
Function: Mainly used to empty and discharge the medium in the pipeline.
Applicable media: dust, sewage pulp, sewage, coal slurry, ash, slag-water mixture, etc.
Application: Mainly used for coal preparation, gangue discharge and slag discharge in mining power plants, and can also be used for sewage treatment.
Features: This valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small size, smooth passage, small flow resistance, light weight, easy installation and disassembly, etc.
