The knife gate valve (also known as Knife Gate Valve) is a commonly used valve type for controlling the flow of fluid media. It is named after its gate or valve plate, which resembles a blade. The valve plate of the knife gate valve can be moved vertically to open or close the flow channel, similar to the action of a blade being opened or closed.
The key features of the knife gate valve include:
1. Valve Plate Shape: The valve plate is typically rectangular or wedge-shaped, resembling a blade. This design enables the valve plate to quickly cut off or open the flow channel when moving.
4. Low Flow Resistance: The knife gate valve has minimal flow resistance, allowing fluid to pass through the valve body with almost no pressure loss. This makes it highly advantageous in applications where reducing flow resistance, minimizing energy consumption, or improving system efficiency is crucial.
5. Simple Structure: The knife gate valve has a relatively simple structure with few main components, making it easy to manufacture, install, and maintain. This lowers operation and maintenance costs while enhancing the valve's reliability and availability.
When choosing a suitable type and specification of the knife gate valve, it is essential to consider specific application requirements and system needs. The knife gate valve is particularly advantageous in specific industrial applications, especially where rapid cutoff of fluid flow is necessary.
