CRV双偏置蝶阀

Butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow. It is often said that butterfly valves can be used to regulate the flow. However, we do not recommend doing this, as it can damage the valve disk and have a negative effect on the sealing properties. They are used in a wide variety of process media and industries especially in water supply, collection, and distribution, as well as pumping stations, and have a broad range of use cases especially in flow isolation. A couple of their key advantages over other valve families are their simple construction and compactness, resulting in the end products being of lighter weights and lower cost and with smaller installation footprints and faster actuation speeds.

CRV蝶阀是法兰双偏心 (双偏置) 型。双偏移或偏心是指这样的事实，即该阀设计涉及阀瓣从阀体的中心或阀杆的旋转轴线的两个偏移。蝶阀的结构相对简单，阀盘的旋转控制流体流动。在关闭位置中，盘阻塞阀孔，而在打开位置中，盘垂直于流动方向定向以允许流动。蝶阀通常提供双向流动和关闭能力。然而，它们不是全通径的，这使得它们不适合清管或擦拭。主体材料为球墨铸铁，内外表面均具有环氧粉末涂层。根据具体的应用要求和技术规范，阀通常由手轮、齿轮或致动器或其组合来操作。我们将在本文后面讨论驱动方法。
