API閘閥(Fa)

閘閥(Fa)的啟閉件是閘闆,閘闆的(De)運動(Dong)方向與流體方向相垂直,閘閥[Fa]隻能作全開和全關 , 不(Bu)能作調節和節流[Liu]。閘闆有兩個(Ge)密封面(Mian) , 常用的模式閘[Zha]闆(Pan)閥(Fa)的兩個密封面形成楔[Xie]形、楔形角随閥門參數而異 , 楔式閘閥(Fa)的閘闆可以(Yi)做成一個[Ge]整 體,叫做剛性閘闆;也可以做成[Cheng]能産生微量變形的(De)閘闆 , 以改(Gai)善(Shan)其工藝性,彌補密封面角度[Du]在加工過[Guo]程[Cheng]中(Zhong)産生的偏差 , 這種閘闆叫做彈性(Xing)閘闆。
法蘭連[Lian]接的API鑄鋼閘(Zha)閥(Fa)适用于ANSI Classl50-2500,工[Gong]作溫度在<600℃的石油、化[Hua]工、火力電站[Zhan]等多種工況的管(Guan)路上,切斷[Duan]或接(Jie)通管路介[Jie]質。适用介(Jie)質為:水、油[You]品、蒸[Zheng]汽等。操作方式有:手動、齒輪傳動、電動、氣[Qi]動等。
