1. The bolts welded onto the valve disc should not be excessively long. If they are too long, they may protrude into the flow passage of the valve body, causing the sealing surface to become misaligned or "overhead," which can prevent proper sealing. During assembly, it is essential to check the bolt length and ensure that the sealing surfaces make full contact for an effective seal.
2. Choose the right adjustment pad, with a thickness slightly less than or equal to the step height of the valve disc's sealing surface. This ensures that the soft gasket fits snugly against the sealing surface and remains in the same plane, enhancing the overall sealing performance.
3. To prevent the compression nut from loosening or falling off, it should be tightened properly and then slightly loosened after securing. This helps maintain the correct tension without over-tightening, which could damage the components.
4. When selecting a valve, consider the properties of the fluid medium being used. Factors such as corrosion resistance and temperature stability should be taken into account to avoid damage caused by chemical reactions or thermal expansion, ensuring long-term reliability.
5. If the sealing surface of the valve seat is severely damaged, it may need to be replaced. However, if the valve core is still in good condition, it can be paired with a new valve seat of the same specification after necessary improvements, saving costs and time.
6. When adjusting the valve, mark the position to avoid sudden or sharp openings. This prevents excessive stress on the gasket, which can lead to premature wear and reduce the service life of the sealing components.
Proper maintenance and attention to detail during installation and operation are crucial for the optimal performance of any valve system. Always follow manufacturer guidelines and use high-quality parts to ensure safety and efficiency.
