阀门英文 电动球阀的工作原理

阀门英文：

Valve：

Valves are mechanical devices that control the flow of fluid and pressure within a system or process. Valves are used in a wide variety of applications, including controlling the flow of water, gas, steam, oil, and other liquids, as well as controlling the pressure of liquids and gases. Valves are available in a variety of materials and sizes, and can be operated manually or automatically.

电动球阀的工作原理：

电动球阀的工作原理是通过电动机驱动，使球阀转动杆杆轴上的螺母，调整球阀的开启角度从而改变流量通过阀体的方向和大小。当电动机的相位转变时，螺母会带动球阀转动杆杆轴上的螺母，从而改变球阀的开启角度，从而调节流量的大小和方向。当电动机转动到预定位置时，电动球阀的位置就稳定了，流量也相应的改变了。
