【摘要】 由于在恶劣的流通介质和工况中Y形截止阀密封面极易磨损 ,使用寿命短。因此提出采用有反馈的变频调速电动驱动装置 ,使阀瓣在整个行程中 ,不同阶段用不同的速度运行 ,从而使阀瓣密封面受到的磨损减小到最低更多还原

【Abstract】 Owing to the sealed surface of Y type globe valve has short lifetime and is usually worn down to damage under poor working conditions,this paper proposes to adopt electric actuator with feedback and the speed adjustment by frequency change that can operate the disc by different speed in different phases of the whole disc moving distance,which will diminish the wearing of sealed surface to the minimum.更多还原
