功能原理 Functional principle

有两种不同型式:阀块型KHB-DN04-25 ,袖套型KHM-DN32-50  There are two different types: valve block type KHB-DN04-25, sleeve type KHM-DN32-50

(KHB，KHM)进口高压球阀旋转控制芯轴使球体从开启位置切换到关闭位置，系统压力将球体推向密封碗的无压侧并无泄漏地切断液流 RETZ品牌 (KHB，KHM) inlet high-pressure ball valve rotates the control spindle to switch the ball from the open position to the closed position, and the system pressure pushes the ball to the non pressure side of the sealing bowl to cut off the liquid flow without leakage

性能特点 Performance characteristics

通过控制手柄芯轴上的指示槽位观察开关位置 Observe the switch position through the indication slot on the control handle spindle

通过限位销和限位垫限定开关位置 Limit switch position through limit pin and limit pad

在控制芯轴密封上装有支撑环 A support ring is installed on the control spindle seal

采用浮球式密封原理，双侧密封、全流量通流便于介质的无阻尼流动容易操作 The floating ball sealing principle is adopted, and the double side sealing and full flow passage are convenient for the undamped flow of medium and easy operation
