清管阀一种高性能球阀,专为恶劣的工业环境而设计,具有多种功能,旨在优化管道清洁和维护。该阀有利于管道清管器的运动,有效去除水垢、沉积物和其他杂质,保持管道的清洁度和流动效率。
欧菲C型球阀采用双偏心设计:C球回转中心(轴心)与C球密封面几何中心(球心)、C球回转中心与阀座密封中心的双偏心设计。阀杆在两个平面上的偏移产生C球旋转+平移的双矢量凸轮运动。阀门关闭时,C球与阀座产生凸轮楔紧的扭矩密封。扭矩密封的动力来自于手柄、齿轮、执行机构,从机械原理上确保不依赖弹簧或工艺压力而实现严密关断。
The Cryogenic Temperature and High Performance Butterfly Valve adopts an offset valve stem and eccentric butterfly plate design. When opening and in the middle position, the valve seat and the butterfly plate do not contact each other, which reduces the friction on the valve seat while reducing the torque, and improves the durability of the valve. It is a high-performance regulating and cutting valve. The valve is designed to handle various media that are most difficult to handle in today's industrial environment, including liquid oxygen, liquid natural gas and other cryogenic liquids.
