Two minutes let you know the cast steel globe valve
截止阀，又称截止阀，是一种强制密封的阀门，所以在阀门关闭时，必须对阀瓣施加压力以强制密封面不泄漏。当介质从阀门下方进入阀门时，克服阻力所需的操作力是阀杆与填料的摩擦和介质压力所产生的推力，关闭阀门的力大于开启阀门的力，因此阀杆的直径应大些，否则会发生阀杆弯曲。按连接方式分为三种：法兰连接、螺纹连接、焊接连接。自密封阀出现后，截止阀改变介质的流动，从阀门顶部进入阀腔，然后在介质压力下，阀门关闭力小，而开启阀门力，阀杆直径可以减小。同时，在介质方面，这种形式的阀门也更加严格。我国的阀门“三向”都规定了阀门的流量，都是自上而下的。截止阀开启时，瓣开启高度为公称通径的25%～30%，流量已达到最大，说明阀门已达到全开位置。因此，阀门的全停位置、阀门行程应确定。表示阀门已达到全开位置。因此，阀门的全停位置、阀门行程应确定。表示阀门已达到全开位置。因此，阀门的全停位置、阀门行程应确定。 【打印】...
