		J41W/Y-16P/25P/40P/64P/100P/160P/R/RL不锈钢截止阀的启闭件是塞形的阀瓣,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)。不锈钢截止阀只适用于全开和全关,不允许作调节和节流。属于强制密封式阀门,所以在阀门关闭时,必须向阀瓣施加压力,以强制密封面不泄漏。当介质由阀瓣下方进入阀门时,操作力所需要克服的阻力,是阀杆和填料的摩擦力与由介质的压力所产生的推力,关阀门的力比开阀门的力大,所以阀杆的直径要大,否则会发生阀杆顶弯的故障。近年来,从自密封的阀门出现后,的介质流向就改由阀瓣上方进入阀腔,这时在介质压力作用下,关阀门的力小,而开阀门的力大,阀杆的直径可以相应地减少。同时,在介质作用下,这种形式的阀门也较严密。我国阀门“三化给”曾规定,的流向,一律采用自上而下。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。
