The imported pneumatic knife gate valve is a mechanical device that controls the flow of pipeline fluid, which has the characteristics of small size, light weight, simple structure, convenient operation, good sealing performance and accurate flow control. It is mainly composed of valve body, valve plate, valve stem, seal and pneumatic actuator, etc. Among them, the design of the valve plate is the core part of the valve, which can be made with different materials and processes according to the needs of different working conditions.
The inlet pneumatic knife gate valve is usually installed at the opening and closing position of the pipeline, which plays the role of cutting off or connecting the fluid medium, and can adjust the flow rate. According to the sealing form, it can be divided into hard seal gate valve and soft seal gate valve;According to the connection type, it can be divided into flange connection valve and assembled valve.
The opening and closing parts of the imported pneumatic knife gate valve are disc or spherical"Floating"The circular ram can be rotated by the handwheel to drive the transmission shaft to rotate to open or close the valve. The pneumatic knife globe valve uses compressed air as the power source to drive the piston to open and close the medium in the gas pipeline, which has a variety of significant advantages, such as low fluid resistance, reliable sealing, good elastic memory, long service life, etc.
Parameters of imported pneumatic knife gate valve:
DN: DN15-DN600mm
Nominal pressure: pn10-pn4.0mpa
Sealing surface material: cemented carbide, ceramic, etc.
Drive mode: The opening and closing of the valve are controlled by compressed air.
Operation: Control the opening and closing speed and force of the valve by controlling the flow and pressure of the compressed air.
Connection: flange connection or clamp connection.
Medium: all kinds of fluid media, such as gas, liquid, slurry, etc.
Operating temperature: between -20 and -250.
Structure: straight-through or angled.
The parameters of the imported pneumatic knife gate valve vary according to the specific use occasions and working conditions, and need to be selected and configured according to the actual situation.
Imported pneumatic knife gate valve has the following advantages:
