进口铸钢法兰截止阀(globe valve),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。
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。
优点:1.结构简单,制造和维修比较方便。2.工作行程小,启闭时间短。3.密封性好,密封面间磨擦力小,寿命较长。
截止阀产品主要包括
进口铸钢法兰截止阀,进口不锈钢截止阀,进口电动截止阀,进口高压截止阀,进口波纹管截止阀,进口蒸汽截止阀,进口锻钢高压截止阀。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
(stop valve,Globe Valve)的启闭件是塞形的阀瓣,密封面呈平面或锥面,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,方工阀门根据阀瓣的这种移动形式,阀座通口的变化是与阀瓣行程成正比例关系。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。Globe Valve opening and closing parts are plug shaped valve, sealing surface flat or cone, the valve along the centerline of the valve seat for linear motion. Stem form of exercise, (generic name: dark bar), but also lift rotating rod, party work valve according to this form of valve, valve seat through the mouth of change is directly proportional relationship between the valve stroke. Therefore, this type of cut-off valve is suitable for cutting or regulation and throttle use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。美国威盾VTON截止阀主要产品有铸钢截止阀,不锈钢截止阀,法兰截止阀,美标截止阀,电动截止阀,球阀截止阀,铬钼钢截止阀,高压截止阀,高温截止阀,高压高温截止阀,低温截止阀,保温截止阀,波纹管截止阀,德标截止阀,美标截止阀,日标截止阀,开关截止阀,锻钢截止阀,焊接截止阀,对焊截止阀,承插焊截止阀等产品。
