            国标截止阀系列有铸钢,不锈钢,合金钢材料,驱动有手动,齿轮传动,电动

            国标截止阀系列

                超达集团专业研制生产的国标截止阀的启闭件是圆柱形的阀瓣,密封面呈平面或锥面,阀瓣沿流体的中心线作直线运动。GB国标截止阀只适用于全开和全关用以接通或截断介质,不允许作调节和节流。在开启或关闭时,阀瓣沿阀座中心线上下移动,介质由阀座下进入,经截止阀阀瓣后出,通常称为“低进高出”,因此在阀体上标出介质流向的箭头,使用时要注意介质流动方向,不能装反。通常采?#38376;?#26681;密封,可旋拧压盖螺母使盘根进一?#25509;?#38400;杆形成严密贴合挤压或更换盘根加以解决。

                国标铸钢截止阀的使用极为普通,但由于开启和关闭力矩较大、结构长度较长,通常公称通径都限制在250mm以下,也有到400mm的。选用时需特别注意进出口方向。?#35805;?50mm以下的截止阀介质大都从阀瓣的下方流入,而200mm以?#31995;?#25130;止阀介质大都从阀瓣的上方流入。这是考虑到阀门的关闭力矩所致。为了减小开启或关闭力矩,?#35805;?00mm以?#31995;?#25130;止阀都设内旁通或外旁通阀门。

            国标截止阀

            国标截止阀产品简介

                国标截止阀适用于DN15~DN200、PN16~PN160的各?#27490;?#36335;上,国标截止阀是截止阀系列中较常用的产品,用于截断或接通管路中的介质。通过选择碳钢、不锈钢、合金钢等阀门材质,超达集团的国标截止阀可?#30452;?#36866;用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。国标截止阀的驱动装置可选用手动、蜗轮传动、气动或电动。国标截止阀?#35805;?#37319;用法兰连接,也可采用对焊连接。API美标截止阀执行ANSI和API标准。

                国标低温截止阀通常指工作温度低于 -110℃ 的阀门,广泛应用于液化天然气,液化石油气体和其它低温行业。可制造适用温度达 -196℃ 的截止阀,全部零件采用液氮进?#26800;?#28201;预处理,完全避免使用过程中密封变形泄露。 

                超达集团?#36718;?#30005;子商务有限公司是超达阀门集团股份有限公司的全?#39318;?#20844;司,专业销售“超达”牌阀门产品。“超达”牌阀门询价电话0577-57755553。

                超达集团除了生产国标截止阀,还生产日标截止阀、氧气截止阀、美标铸钢截止阀等。

            国标截止阀产品特点

                超达研制生产的中国标准截止阀的阀瓣和阀座的密封面采用不同硬度的司太立(Stellite)钴基硬质合金堆焊而成,密封可靠、硬度高、耐磨、耐高温、耐腐蚀、抗擦伤性能好、寿命长。
