二位三通，二位五通截止阀原理K25JD-25W.K23JD-25W
点击次数：1695 发布时间：2009-4-26
: 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,...
K23JD-10W.K23JD-15W.K23JD-25W.K25JD-10W.K25JD-15W.K25JD-25W截止阀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六时K23JD-10W.K23JD-15W.K23JD-25W.K25JD-10W.K25JD-15W.K25JD-25W，操作力所需要克服的阻力，是阀杆和填料的磨擦力与由介质的压力所产生的推力，关阀门的力比开阀门K23JD-10W.K23JD-15W.K23JD-25W.K25JD-10W.K25JD-15W.K25JD-25W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，K23JD-10W.K23JD-15W.K23JD-25W.K25JD-10W.K25JD-15W.K25JD-25W截止阀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。K23JD-10W.K23JD-15W.K23JD-25W.K25JD-10W.K25JD-15W.K25JD-25W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，截止阀的流向，一律采用自上而下。
K23JD-10W.K23JD-15W.K23JD-25W.K25JD-10W.K25JD-15W.K25JD-25W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。
K23JD-10W.K23JD-15W.K23JD-25W.K25JD-10W.K25JD-15W.K25JD-25W截止阀，也叫截门，是使用zui广泛的一种阀门，它之所以广受欢迎，是由于开闭过程中密封面之间摩擦力小，比较耐用，开启高度不大，制造容易，维修方便，不仅适用于中 低压，而且适用于高压。
K23JD-10W.K23JD-15W.K23JD-25W.K25JD-10W.K25JD-15W.K25JD-25W截止阀的闭合原理是，依靠阀杠压力，使阀瓣密封面与阀座密封面紧密贴合，阻止介质流通。
K23JD-10W.K23JD-15W.K23JD-25W.K25JD-10W.K25JD-15W.K25JD-25W截止阀只许介质单向流动，安装时有方向性。截止阀的结构 长度大于闸阀，同时流体阻力大，*运行时，密封可靠性 不强。
