功能原理 Functional principle

(KHB3K)进口二位三通高压球阀旋转控制芯轴使液流按球口形状换向，同时无泄漏地截断对立的一侧。系统压力把球体推向密封的无压侧。球体无泄漏地截断从接口1到接口2或3的液流。当流向从接口2或3到接口1时，会有少许泄漏，但取决于压力。转向过程中三个接口互相连接。retz品牌 (KHB3K) The imported two position three-way high pressure ball valve rotates the control spindle to make the liquid flow reverse according to the shape of the ball mouth, while cutting off the opposite side without leakage. The system pressure pushes the ball towards the non pressure side of the seal. The ball can cut off the liquid flow from interface 1 to interface 2 or 3 without leakage. When the flow direction is from interface 2 or 3 to interface 1, there will be a little leakage, but it depends on the pressure. The three interfaces are connected to each other during steering.
