原装力士乐REXROTH截止阀，力士乐截止阀简单介绍：
力士乐REXROTH截止阀又称截门阀，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。按连接方式分为三种：法兰连接、丝扣连接、焊接连接。从自密封的阀门出现后，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。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。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。

，截止阀（stopvalve,GlobeValve）的启闭件是塞形的阀瓣，密封上面呈平面或海锥面，阀瓣沿阀座的中心线作直线运动。阀杆的运动形式，（通用名称：暗杆），也有升降旋转杆式可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。因此，这种类型的截流截止阀阀门非常适合作为切断或调节以及节流用。由于该类阀门的阀杆开启或关闭行程相对较短，而且具有非常可靠的切断功能，又由于阀座通口的变化与阀瓣的行程成正比例关系，非常适合于对流量的调节。
