📖 Terms & Definitions / 术语和定义 ai_extracted
- 电动切换阀 step valve / step valve
- 一种步进电动机驱动阀，设置有一个进口和一个或多个出口，按预设的程序控制步进电动机的运转， 电动机转子直接驱动滑块，在预设工作位置改变出口管的开闭状态，从而控制制冷剂流向的电动阀。
- A stepping motor-driven valve, equipped with one inlet and one or more outlets, controls the operation of the stepping motor according to a preset program. The motor rotor directly drives a slider to alter the open/close state of outlet tubes at predetermined working positions, thereby regulating the flow direction of refrigerant in an electric valve.
- 流量特性 air flow late / Flow characteristics
- 流过电动阀各出口的流量与输入步进电动机线圈的脉冲数之关系。
- The relationship between the flow rate through each outlet of the electric valve and the number of pulses input to the stepper motor coil.
