Non-guided Structure Features
1. The innovative non-guided gate design eliminates the need for a guide hole, resulting in an exceptionally compact, lightweight valve structure that optimizes space and weight efficiency.
2. The gate's versatile design offers V-shaped, semi-circular, or pentagonal channels, empowering the valve with exceptional regulating capabilities to adjust effortlessly to any opening degree. This flexibility ensures precise flow management tailored to the pipeline system's dynamic requirements (refer to the diagram on the right for clarity).
3. Engineered for durability, the two floating valve seats incorporate a soft-hard composite seal that promises an extended service life. In scenarios where the valve experiences abnormal internal cavity pressure, the intelligent floating valve seat efficiently releases excess high pressure back into the pipeline, maintaining safety and integrity.
4. Thoughtfully designed with grease injection valves located at the external seats of the valve body, this feature enables the injection of sealing grease to counteract leakage caused by seal wear, effectively preventing valve leakage and enhancing reliability during use.
5. Strategically positioned, a drain valve at the bottom of the valve body efficiently eliminates accumulated impurities, ensuring the valve's optimal performance and longevity.
Guided Gate Structure Diagram
1. When fully opened, the valve's guide hole in the gate aligns seamlessly with the valve body channel, creating a straight pipe section that facilitates direct media purging. Please refer to the above diagram for visual reference.
2. Throughout the gate's operational travel, the valve seat consistently maintains contact and alignment with the gate. The soft valve seat ingeniously scrapes away impurities during operation, rendering the flat gate valve ideal for media containing suspended particles and fibers, while safeguarding the seal surface from potential damage due to valve body thermal deformation.
3. Crafted for longevity, the two floating valve seats integrate a soft-hard composite seal, ensuring an extended service life.
4. In the event of an unexpected rise in valve cavity pressure, the floating valve seat proactively releases excess high pressure back into the pipeline, maintaining safe operation.
5. A strategically placed drain valve at the bottom of the valve body effectively purges accumulated impurities, safeguarding the valve's efficiency and durability.
