截止阀的启闭件是圆柱形的阀瓣，密封面呈平面或锥面，阀瓣沿流体的中心线作直线运动。阀杆的运动形式，有升降杆式（阀杆升降，手轮不升降），也有升降旋转杆式（手轮与阀杆一起旋转升降，螺母设在阀体上）。截止阀只适用于全开和全关，定做时允许作调节和节流。截止阀开启时，阀瓣的开启高度，为公称直径的25%～30%时，流量已达到zui大，表示阀门已达全开位置。所以截止阀的全开位置，应由阀瓣的行程来决定。以上内容均根据学员实际工作中遇到的问题整理而成，供参考，如有问题请及时沟通、指正。上海申弘阀门有限公司主营阀门有：截止阀,角式截止阀,电站截止阀,波纹管截止阀,真空截止阀,抗生素截止阀,水封截止阀,氧气截止阀,节流截止放空阀,低温截止阀，高温高压截止阀,气动截止阀,电动截止阀,氨气截止阀,止回阀，闸阀,安全阀、保温阀、低温阀、球阀蝶阀、过滤器、放料阀、隔膜阀、旋塞阀、柱塞阀、平衡阀、调节阀、疏水阀、管夹阀、排污阀、排气阀、排泥阀、气动阀门、电动阀门、高压阀门、中压阀门、低压阀门、水力控制阀、真空阀门、衬胶阀门、衬氟阀门。
截止阀的工作原理
打个比方，假设一个带盖的水缸，水从缸底进入，从缸口流出，缸盖就相当于阀的关闭件。要是用手向上提起缸盖，就相当于截止阀的工作原理。要是用手向旁边移开缸盖，相当于闸阀的工作原理。本阀适用于PN 1.6～42MPa，工作温度在-29～+570℃的石油、化工、火力电站冶金、城建等各种工况的管路上，切断或接通管路介质。根据用户不同需要，驱动装置可配电动、气动、液动和手动。
