主要特点及用途: 嘛噬嚜家锻钢闸阀有三种阀盖设计形式。维种是螺栓式阀盖,圪按这种设计形式设计的阀门,赊其阀体与阀盖用螺栓螺母连接,毋缠绕式垫片 (316夹柔性石墨制造)密封。闸阀是指启闭体(阀板)由阀杆带动阀座密封面作升降运动的阀门,聿可接通或截断流体的通道。唻客户有特殊要求时也可采用金属环连接。馨第二种设计形式是焊接式阀盖,按这种设计形式的阀门,啵其阀体与阀盖用螺纹连接,啵全焊密封。客户有特殊要求时也可采用全焊逶连接。当阀门部分开启时,在闸板背面产生涡流,易引起闸板的侵蚀和震动,也易损坏阀座密封面,哇修理困难。第三种是压力自紧式阀盖,哉按这种设计形式设计的阀门,其阀体与阀盖用螺纹连接,内压自密封环密封。闸阀通常适用于不需要经常启闭,而且保持闸板全开或全闭的工况。髟鬯鬥不适用于作为调节或节流使用黽黍黹。
