材料 Material 钢制部件:SUS304,SUS316L 密封圈: 硅橡胶 (VMQ)、氟橡胶(FPM)、三元乙丙(EPDM) Steel parts:SUS304,SUS316L Seal: silicone (VMQ) , fluoroelastomer (FPM) , EPDM 应用 Applications 该类型阀门系列是一款卫生型自动或手动操作的蝶阀系列,广泛适用于不锈钢管道系统内调节介质流量的一类阀门。 The series of this valve are sanitary pneumatic or manual butterfly valves, which are widely used in stainless steel pipeline system to control and regulate medium flow. 工作原理 Working Principle 该类型阀门既可以通过一个电动执行器或气动执行器进行远程遥控操作,也可以通过一个手柄进行人为操控。 电动执行器或气动执行器是将一个活塞的轴向运动转换为阀门轴的90°旋转,实现对管道流体的控制和开/关任务。气动执行器装置有三种标准:常开(NO)型,常闭(NC)型,气/气(A/A)型。 鸭嘴式手动操作用的多位手柄可通过15°位置的调节将阀门机械式锁定在其开启或关闭的12位子上,达到控制介质流量的目的: 拉杆式手动操作用手柄通过4个多功能定位,将阀门机械式锁定在其开启或关闭的4个位子上,也达到控制介质流量的目的。 This kind of valve can be handled by manual an electric actuator, and also can be handled by a pneumatic actuator. Electric actuator or pneumatic actuator covert the axial movement of piston to be 90° rotation of valve shaft. So that the valve can be open or close to achieve the requirement of control and open/close for the pipeline system. They have three type of actuator : normally open (NO) , normally closed (NC), air/ air (A/A). Muti-position handle regulates the valve by 15 ° in its open or close 12 seats achiening control of medium flow purpose: Pulling handle regulates the valve through four multi-function positioning, in its open or close four position,also achieves control of medium flow purpose.
