Imported manual knife gate valve is a commonly used type of valve, its main characteristics are simple structure, small size, light weight, good sealing, corrosion resistance, flexible operation and other advantages. It is a valve with a knife-edged ram that can easily pass through solid particles in the pipeline, such as pulp, sewage, coal slurry, ash and cement mixture, and other media.
The imported manual knife gate valve is mainly composed of valve body, valve, sealing ring, suspension device, handle, etc. The valve has a knife-like design that can easily cut off these media. Its operation mode is usually manual operation, but it can also be controlled by electric, pneumatic, hydraulic and other methods.
Imported manual knife gate valve has a wide range of applications, which can be used to control various media such as slurry, sewage, oil, natural gas, chemicals, etc., and is widely used in transportation pipelines, sewage treatment, mine beneficiation, chemical industry and other fields. The ram has a shear function, which can scrape off the adhesive on the sealing surface and automatically remove debris. Stainless steel ram prevents seal leakage caused by corrosion.
The imported manual knife gate valve is mainly composed of valve body, valve cover, ram, sealing ring, transmission device, etc. Among them, the valve body is the core component of the whole valve, which is connected with the pipeline and plays a role in controlling the flow of the medium. The bonnet is the top part of the valve body, which protects the spool from direct impact of the medium. The ram is the control component of the valve, and the opening and closing state of the valve is controlled by moving the ram up and down. The sealing ring is used to seal the valve and can prevent the leakage of the medium. The transmission device is used to drive the valve action, which can be manual, electric, pneumatic, etc.
The ram of the imported manual knife gate valve is designed in the shape of a knife edge, which can easily cut off the solid particles in the medium. When the valve is closed, the bladed ram forms a tight seal with the valve body, preventing media leakage. At the same time, the valve adopts an open rod design, which can easily observe the degree of opening of the valve.
The advantages of imported manual knife gate valve mainly include:
1.The structure is simple and compact, the design is reasonable, the light material is saved, the sealing is reliable, the operation is light and flexible, the volume is small, the channel is smooth, the flow resistance is small, the weight is light, the installation is easy, the disassembly is easy, etc.
2.Can be at a working pressure of 10mpa-2.5MPa, operating temperature -29-650 under the condition of normal operation.
3.The sealing surface is sealed by the medium pressure, that is, the medium pressure presses the sealing surface of the ram on the opposite side of the valve seat to ensure the sealing of the sealing surface.
The ram must be pressed when closing the valve.
4.The ram has a shear function, which can scrape off the adhesive on the sealing surface and automatically remove debris.
5.Stainless steel ram prevents seal leakage caused by corrosion.
6.It can also be installed in horizontal pipes, or in inclined pipes.
