自由侧翻式拍门无水闭门运动特性研究

Movement Characteristics Research of Side-Turn-Over Flap Value Working in Pump Stations without Water

根据自由侧翻式拍门的结构特点,研究了该种拍门的工作原理,对其在无水条件下的闭门运动进行了分析,推导了闭门运动方程,求解了闭门时门体对门座的撞击力,并与其它形式的拍门进行了对比研究。研究结果表明:自由侧翻式拍门在无水条件下对门座的撞击力小很多,工作更安全。

Based on the structure of side-turn-over flap value and working without water, We study Working principle of side-turn-over flap value, analyze law of motion, deduce the equations of motion, calculate collision force on value seat, and comparatively study other forms of flap value. The research suggests： side-turn-over flap value can work with more small collision force on value seat, work more safety.
