上海融骏阀门锻钢闸阀有三种体盖衔接设计方式。第一种是体盖螺栓衔接,按这种衔接方式设计的阀门,其阀体与阀盖用螺栓衔接,缠绕式垫片密封,长处是便于维修。第二种体盖焊连续接,按这种衔接方式设计的阀门,其阀体与阀盖全焊密封,长处是无外走漏。第三种是压力自紧式阀盖,按这种衔接方式设计的阀门,其阀体与阀盖用螺纹衔接,内压自密封环密封,长处是外部压力越大,其密封功能越好。

rjvalve forged steel gate valve has three types of bonnet. One is bolted bonnet,which the body is connected with bonnet by
bolts and sealed by spiral gasket withadvantages of convenient maintenance; one is welded bonnet, which the body is
fullywelded with sealing bonnet of no leakage; another is pressure-in bonnet, which thebody is screwed into the bonnet and
sealed by inner pressure-in ring with bettersealing ability for higher pressure.
