DZ61Y低溫鍛鋼閘閥是指能夠在低溫≤－196o 工況下使用的閥門, mso-hansi-font-family:"Times New Roman"">通常把工作溫度低于-40 "Times New Roman"">℃的閥門稱為低溫閥門. "Times New Roman"">低溫閥門是石油化工、空氣分離、天然氣等工業(yè)不可缺少的重要設(shè)備之一, "Times New Roman"">其質(zhì)量的優(yōu)劣決定著使用企業(yè)能否安全、經(jīng)濟、持續(xù)地生產(chǎn)。低溫閥門的主要特點是所有零部件的材料必須經(jīng)過深冷處理。

DZ61Y鍛鋼低溫閘閥產(chǎn)品詳細介紹:

DZ61Y低溫鍛鋼閘閥閥門有二種閥蓋設(shè)計形式。第一種是螺栓式閥蓋，按這種設(shè)計形式設(shè)計的閥門，其閥體與閥蓋用螺栓螺母連接，纏繞式墊片 (31 6夾柔性石墨制造) mso-hansi-font-family:"Times New Roman"">密封。客戶有特殊要求時也可采用金屬環(huán)連接。第二種設(shè)計形式是焊接式閥蓋，按這種設(shè)計形式的閥門，其閥體與閥蓋用螺紋連接，全焊密封?？蛻粲刑厥庖髸r也可采用全焊逶連接。閘閘、截止閥、球閥都可設(shè)計成低溫閥。為了能在-196 mso-hansi-font-family:"Times New Roman"">℃(320oF) "Times New Roman"">的低溫下使用，一般將閥門設(shè)計成加長式閥蓋。
