锻钢截止阀

2024-01-21 14:29:46 来源:本站
锻钢截止阀是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。因此,这种类型的阀门非常适合作为切断或调节以及节流使用,在开启和关闭过程中,由于阀瓣于阀体密封面间的摩擦力比闸阀小,因而耐磨,开启高度一般仅为阀座通道直径的1/4,因此比闸阀小的多。通常在阀体和阀瓣上只有一个密封面,因而制造工艺性比较好,便于维修,在高温、高压介质的管路或装置上宜选用截止阀,如火电厂、核电站,石油化工系统的高温、高压管路上,也可适用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。
