产品详细信息
产品介绍:
法兰连接美标提升式硬密封旋塞阀适用于公称压力CLASS150LB~2500LB，工作温度-29~550℃的石油、化工、制药、化肥、电力行业等各种工况的管路上，切断或接通管路介质。
结构特点:
1、产品结构合理、密封可靠、性能优良、造型美观;
2、阀门的启闭过程是在密封面脱离的状态下进行的，不会造成密封面的磨损。
3、法兰提升式硬密封旋塞阀双向流动，安装使用更方便。
4、零件材质及法兰尺寸可根据实际工况或用户要求合理选配，满足各种工程需要。
阀门的启闭工作原理
旋塞阀的启闭过程:开启阀门时，要先旋转手轮，使塞子上升，于密封面脱离，再旋转手柄90°，使塞子的通道和阀体的通道相通，达到开启的目的。而阀闭的过程是先旋转手柄90°，使塞子的通道和阀体的通道垂直，再旋转手轮，使塞子下降，达到密封。
