一、Z41Y鍛鋼法蘭閘閥概述：
鍛鋼閘閥有三種閥蓋設(shè)計(jì)形式.*種是螺栓式閥蓋,按這種設(shè)計(jì)形式設(shè)計(jì)的閥門,其閥體與閥蓋用螺栓螺母連接,纏繞式墊片（316夾柔性石墨制造）密封.客戶有特殊要求時(shí)也可采用金屬環(huán)連接.二種設(shè)計(jì)形式是焊接式閥蓋,按這種設(shè)計(jì)形式的閥門,其閥體與閥蓋用螺紋連接,全焊密封.客戶有特殊要求時(shí)也可采用透焊連接.三種是自密封閥蓋,按這種設(shè)計(jì)形式設(shè)計(jì)的閥門,其閥體與閥蓋用螺紋連接,內(nèi)壓自密環(huán)密封。
鍛鋼閘閥是指關(guān)閉件(閘板)沿通路中間線的垂直方向移動(dòng)的閥門。鍛鋼閘閥在管路中主要作切斷用。鍛鋼閘閥是使用很廣的一種閥門，一般口徑DN≤50的切斷裝置都選用它。鍛鋼閘閥比較常見。
