Non-guided Structure Features
1. With a remarkable streamlined design, the gate boasts an absence of guide holes, resulting in a remarkably compact structure. This innovation contributes to a smaller size and lightweight valve, making it ideal for space-constrained applications.
2. Embracing versatility, the gate can be meticulously crafted with V-shaped, semi-circular, or pentagonal channels. This customization grants the valve exceptional regulating capabilities, adept at adjusting to any opening degree, precisely meeting the flow requirements of varied pipeline systems (refer to the right diagram for clarity).
3. Engineered for durability, the two valve seats are independently floating and incorporate a sophisticated soft-hard composite seal. This design guarantees an extended service life. In instances of abnormal internal cavity pressure escalation, the floating valve seat ingeniously releases excess pressure into the pipeline, ensuring safety and reliability.
4. Strategically placed, grease injection valves adorn the external seats of the valve body. In the event of leakage triggered by wear in the seal pair, the injection of sealing grease here effectively prevents further valve leakage, ensuring uninterrupted performance.
5. Thoughtfully integrated, a drain valve resides at the bottom of the valve body. It efficiently expels accumulated impurities, maintaining optimal valve performance and enhancing longevity.
Guided Gate Structure Diagram
1. Ingeniously designed, when the valve reaches full openness, the guide hole within the gate aligns seamlessly with the valve body channel. This alignment forms a straight pipe section, enabling unhindered media purging (as illustrated in the above diagram).
2. Throughout the gate's dynamic opening or closing motion, the valve seat consistently contacts and aligns with the gate. The resilient soft valve seat plays a crucial role by automatically sweeping away impurities during operation. This feature makes the flat gate valve especially suitable for media containing suspended particles and fibers, while also safeguarding the seal surface from potential damage due to thermal deformation of the valve body.
3. Designed for resilience, the two valve seats are floating and equipped with a soft-hard composite seal, ensuring they stand the test of time with a prolonged service life.
4. In scenarios where the valve cavity pressure experiences an abnormal surge, the floating valve seat acts autonomously, releasing the excess high pressure into the pipeline, thus averting potential complications.
5. As a safeguard against impurity buildup, a drain valve is strategically positioned at the bottom of the valve body, facilitating the discharge of accumulated impurities and maintaining pristine internal conditions.
