Zusammenfassung:	The utility model relates to an NB-IoT (Narrow Band Internet of Things) control valve. The NB-IoT control valve comprises a valve body, a control valve lower cover and a control valve upper cover which are sequentially arranged from bottom to top. The motor assembly is arranged on the right side of the bottom of an inner cavity of the control valve lower cover, the circuit board is fixedly connected to the top of the control valve upper cover, the control valve upper cover and the control valve lower cover are arranged in an up-down split mode, one ends of the control valve upper cover and the control valve lower cover are hinged, and the other ends of the control valve upper cover and the control valve lower cover are buckled, so that maintenance of the control valve is facilitated; the circuit board located on the top of the control valve upper cover is connected with and separated from the control valve upper cover and the circuit board through the adjusting assembly. When the whole circuit board needs to
