截止閥應(yīng)用很廣泛,主要用于壓力較高的及口徑較小的場(chǎng)合,一般只生產(chǎn)到DN400,更大的口徑規(guī)格僅應(yīng)用于特殊管道。列如,大型氧氣管道,由于其他閥類存在摩擦易產(chǎn)生靜電起火,所以采用大口徑不銹鋼截止閥。
J41H/W-16C/P不銹鋼截止閥工作原理:
不銹鋼截止閥閥桿一般都做旋轉(zhuǎn)升降運(yùn)動(dòng),手輪固定在閥桿頂端。當(dāng)順時(shí)針方向旋轉(zhuǎn)手輪時(shí),閥桿螺紋下旋,,閥瓣密封面與閥座密封面緊密接觸,截止閥達(dá)到關(guān)閉狀態(tài);當(dāng)逆時(shí)針方向旋轉(zhuǎn)手輪時(shí),閥桿螺紋上旋,閥瓣密封面與閥座密封面脫開,截止閥開啟。
J41H/W-16C/P不銹鋼截止閥閥體形式:
不銹鋼截止閥閥體形式為“T”型閥體,它具有低流動(dòng)特性和較高的壓降,可以用于快速節(jié)流,如在繞過控制閥的旁路上。也可以用于僅要求節(jié)流不考慮壓力降的場(chǎng)合。
