阀门在全开时，通道平滑为直线，流阻系数极小，无压力损失，可通毛球清扫管线。
When fully opened, the valve's channel is smooth and linear, with an extremely small flow resisting coefficient and no pressure loss, and the pipeline can be cleaned with hair-ball through it.
介绍了一套阀门流量流阻系数测试装置的设计特点、工作原理、主要设备选型以及测试能力。
The design feature, work elements, the main equipment choose and test ability and so on of one test device for flux characteristics and resistance coefficient of valve were introduced.
其缺点主要是流阻系数比较大，因此造成压力损失，特别是在液压装置中，这种压力损失尤为明显。
Its shortcoming is mainly the resistance to flow coefficient is quite big, therefore creates the pressure loss, in the hydraulic unit, this pressure loss especially is specially obvious.
