進口截止閥—美國威盾VTON品牌,(stop valve,Globe Valve)截止閥的啟閉件是塞形的閥瓣,密封面呈平面或錐面,閥瓣沿閥座的中心線作直線運動。閥桿的運動形式,(通用名稱:暗桿),也有升降旋轉桿式,方工閥門根據(jù)閥瓣的這種移動形式,閥座通口的變化是與閥瓣行程成正比例關系。因此,這種類型的截流截止閥閥門非常適合作為切斷或調節(jié)以及節(jié)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由于該類閥門的閥桿開啟或關閉行程相對較短,而且具有非??煽康那袛喙δ?,又由于閥座通口的變化與閥瓣的行程成正比例關系,非常適合于對流量的調節(jié)。美國威盾VTON截止閥主要產(chǎn)品有鑄鋼截止閥,不銹鋼截止閥,法蘭截止閥,美標截止閥,電動截止閥,球閥截止閥,鉻鉬鋼截止閥,高壓截止閥,高溫截止閥,高壓高溫截止閥,低溫截止閥,保溫截止閥,波紋管截止閥,德標截止閥,美標截止閥,日標截止閥,開關截止閥,鍛鋼截止閥,焊接截止閥,對焊截止閥,承插焊截止閥等產(chǎn)品。
