进口V型球阀，V形调节旋转阀性能描述 Performance description

V型球阀(高压V形旋转阀)的启闭件是带特殊V型开口的半球体，具有锋利的刃口。在球体回转过程中，密封面具有强有力的切断力和自清洁功能。球体的V型开口与阀座流道形成一个扇形区域，在回转过程中可改变流道截面积，形成对介质的线性等比例精确调节  RETZ The opening and closing parts of V-shaped ball valves (high-pressure V-shaped rotary valves) are hemispheres with special V-shaped openings, with sharp edges. During the rotation of the ball, the sealing face has strong cutting force and self-cleaning function. The V-shaped opening of the ball and the valve seat flow channel form a sector area, which can change the sectional area of the flow channel during the rotation process, forming a linear and equal proportion accurate adjustment of the medium
