Revolutionary Patented Technology in Eccentric Expanded Ball Valves in China

The eccentric expanded metal sealed ball valve is a ball valve with unique structure and superior performance. It achieves precise control of the fluid medium through eccentric design and expanded sealing structure. However, during long-term use, the sealing surface of the ball valve may affect the sealing effect due to wear. For this reason, the development of an eccentric expanded metal sealed ball valve with a wear self-compensation structure has become an important task.

I、Features of eccentric expanded metal sealed ball valve

1. Structural advantages: The eccentric design reduces the friction between the sealing surface and the valve seat when the ball valve is opened and closed, effectively reducing wear.

2. Sealing performance: The expanded sealing structure ensures that the ball valve can still maintain good sealing performance under high pressure difference conditions.
3. Wear resistance: The metal sealing surface has high wear resistance and is suitable for conveying abrasive media.

II、Analysis of patented technology of wear self-compensation structure

1. Technical principle: This patented technology sets a special compensation mechanism. When the sealing surface is worn, the compensation mechanism can automatically adjust the position of the sealing surface to restore the sealing effect.

2. Structural composition: The wear self-compensation structure mainly includes compensation springs, compensation sliders, guide mechanisms and drive mechanisms.

3. Working principle: When the sealing surface wears and the sealing effect decreases, the compensation spring pushes the compensation slider to move, and the sealing surface is adjusted to a suitable position through the guide mechanism to achieve self-compensation.

4. Patent advantages: This wear self-compensation structure can effectively extend the service life of the ball valve, reduce maintenance costs, and improve the reliability and safety of the system.

The patented technology of the wear self-compensation structure of the eccentric expansion metal sealing ball valve provides an innovative solution for the valve industry. This structure not only improves the sealing performance and service life of the ball valve, but also reduces maintenance costs, with significant economic and social benefits.
