FLOW CONTROL VALVE

原文（中国語）

A flow control valve is provided, including: a valve body defining an inlet and an outlet, and including a transparent tube; and a control module including a control unit, a sensor assembly, a driving source and a valve core. The driving source cooperates with the valve core. The sensor assembly is located at an outer side of the transparent tube, and the sensor assembly is configured to detect a flow rate of bubbles. When the control unit monitors that the flow rate of the bubbles exceeds a threshold, the control unit controls the driving source to operate to make the valve core reduce a gas inflow at the inlet. When the control unit monitors that the flow rate of the bubbles is lower than threshold, the control unit controls the driving source to operate to make the valve core increase the gas inflow at the inlet.
