蜗轮球阀
蜗轮球阀只需要用旋转90度的操作和很小的转动力矩就能关闭严密。完全平等的阀体内腔为介质提供了阻力很小、直通的流道。通常认为球阀最适宜直接做开闭使用,但近来的发展已将球阀设计成使它具有节流和控制流量之用。球阀的主要特点是本身结构紧凑,易于操作和维修,适用于水、溶剂、酸和天然气等一般工作介质,而且还适用于工作条件恶劣的介质,如氧气、过氧化氢、甲烷和乙烯等。球阀阀体可以是整体的,也可以是组合式的。
The worm gear ball valve only needs to rotate 90 degrees and a small rotating torque to close tightly. The completely equal inner cavity of the valve body provides the medium with a small resistance and a straight flow path. It is generally considered that ball valve is most suitable for direct opening and closing, but in recent development, ball valve has been designed for throttling and flow control. The main characteristics of ball valve are its compact structure, easy operation and maintenance, suitable for water, solvent, acid, natural gas and other general working media, but also suitable for the working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene. The valve body can be integral or combined.
