Audited Supplier Knife-shaped gate valve, also known as knife-shaped gate valve, knife-shaped gate valve, is suitable for pipelines with suspended particles, fibrous materials pulp, sewage, coal slurry, ash and slag cement mixture and other media, which are cut off by knife-shaped gate plates that can cut fiber materials. The valve body does not actually have a chamber, the gate is raised and lowered in the side guide groove, and is pressed against the seat by the bottom lug. If high dielectric sealing is required, the O-seal seat can be used to achieve a two-way seal. According to the driving mode, it is divided into manual knife gate valve, pneumatic knife gate valve and electric knife gate valve. Knife gate valve operation is light and flexible, small size, smooth channel, small flow resistance, light weight, easy to install, easy to disassemble, nominal size DN50~DN800, can be in the working pressure 0.6MPa~1.6MPa, the use temperature ≤100ºC under the condition of normal work. The knife gate valve has a shearing function, which can scrape the adhesive on the sealing surface and automatically remove debris. Stainless steel ram prevents leakage of seals caused by corrosion.
Function: Mainly used to empty and discharge the medium in the pipeline.
Applicable media: dust, sewage pulp, sewage, coal pulp, ash, slag water mixture, etc.
Application: It is mainly used for coal preparation, waste discharge and slag discharge in mine power plant, and can also be used for sewage treatment.
Features: The valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small size, smooth channel, small flow resistance, light weight, easy installation, easy disassembly and so on
Other technical parameters Note:
