Non-guided Structure Features
1. This innovative gate is ingeniously crafted without a guide hole, resulting in an impressively compact structure. Its diminutive size and lightweight nature make it a marvel of engineering brilliance.
2. Expertly designed with versatile channels-be it V-shaped, semi-circular, or pentagonal-this gate empowers the valve with exceptional regulating prowess, adapting seamlessly to any desired opening degree. It meets the precise flow requirements of pipeline systems with unparalleled precision (see the right diagram).
3. The valve's engineering genius shines through its dual floating valve seats, which incorporate a robust soft-hard composite seal. This ensures an extended lifespan, while its automatic pressure relief feature safeguards the system by releasing excess internal cavity pressure into the pipeline when needed.
4. Enhanced with grease injection valves located at the external seats, this valve offers a proactive solution for potential leakage. By injecting sealing grease, it effectively curbs leaks caused by seal pair wear, maintaining optimal performance.
5. At the heart of clean operations lies the strategically placed drain valve at the bottom, expertly tasked with expelling accumulated impurities to keep the valve operating smoothly.
Guided Gate Structure Diagram
1. When fully opened, this valve aligns the guide hole in the gate with the valve body channel, ingeniously transforming it into a straight pipe section. This alignment allows for seamless direct media purging, as illustrated in the diagram above.
2. Throughout the gate's opening and closing journey, the valve seat maintains constant contact, adeptly fitting the gate. The soft valve seat excels in automatically scraping away impurities, making this flat gate valve ideal for media containing suspended particles and fibers. It also adeptly prevents seal surface damage caused by thermal deformation.
3. Featuring dual floating valve seats with sophisticated soft-hard composite seals, this system ensures longevity and reliable performance.
4. In instances of abnormal valve cavity pressure rise, the floating valve seat is designed to automatically channel the excess pressure back into the pipeline with precision.
5. The strategically placed drain valve at the base efficiently purges accumulated impurities, ensuring the valve remains free from obstructions and functions optimally.
