產(chǎn)品結(jié)構(gòu)特點 Construction features 鍛鋼法蘭端閘閥有三種閥蓋設(shè)計形式。種是螺栓式閥蓋，按這種設(shè)計的閥門，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）?？蛻粲刑厥庖髸r也可采用金屬環(huán)連接。 There are three types of bonnet design for forged flange end valves. The first type is bolted bonnet, which is designed to connect the valve body to the bonnet with bolt nuts and coil gasket (316 clip flexible graphite). Metal ring connections may also be used when customers have special requests. 適用介質(zhì)：水、氣、油品、天然氣和酸堿腐蝕性介質(zhì) 適用溫度：-196~425℃ 驅(qū)動方式：手動、氣動、電動等 公稱壓力：1.6~16.0MPa 公稱通徑：DN15~50mm Applicable media: water, gas, oil, gas and acid and alkali corrosive medium Applicable temperature: -196~425℃ Driver: manual, pneumatic, electric, etc Nominal pressure: 1.6~16.0MPa Nominal size: DN15~50mm 試驗壓力 Test prssure 閘閥結(jié)構(gòu)長度和外接尺寸 Main connection dimensions
