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)。客戶有特殊要求時也可采用金屬環(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.
