1. Structural Design and Sealing Mechanism
The through conduit knife gate valve relies on a simple yet effective structure for optimal fluid control.
- Gate Blade and Seat: The valve's core components, the gate blade and seat, form a tight seal through continuous contact. The gate blade features a circular aperture for precise fluid control.
- Groove-Free Design: Unlike other valves, the absence of grooves in the valve body minimizes obstruction, ideal for conveying granular media in powder equipment pipelines.
- Adaptable Sealing: The sealing mechanism can be tailored to incorporate either soft or hard sealing, offering damage resistance and extended longevity.
2. Operational Principles
In operation, the gate blade of the through conduit knife gate valve offers swift and precise control over fluid flow.
Closing Sequence: When closing, the gate blade fully inserts into the valve body, effectively cutting off the connection between upstream and downstream flow paths.
Opening Procedure: Upon opening, the gate blade quickly retracts from the flow channel, restoring fluid passage with efficiency.
Opening Procedure: Upon opening, the gate blade quickly retracts from the flow channel, restoring fluid passage with efficiency.
3. Features and Advantages
Key features of the through conduit knife gate valve include:
- Integral design for reduced fluid resistance and enhanced operational flexibility.
- Dual-plane bearing design for the transmission screw drive, minimizing friction and ensuring smooth valve opening.
