Super-small flow regulating valve

The utility model relates to the technical field of regulating valves, and provides a super-small flow regulating valve. The super-small flow regulating valve comprises an executing mechanism and a valve assembly. The executing mechanism comprises a thin film type executing assembly, a push rod of the thin film type executing assembly penetrates into a hole of a sliding plate, and the push rod is fixedly connected with the sliding plate through a fastener. One end of the push rod is inserted in a guiding element of a transmission case. One end of a sliding plate pin is arranged in a sliding plate groove, and one end of the sliding plate pin is connected with the sliding plate groove in a sliding mode. The other end of the sliding plate pin is arranged in a regulating groove of a rocker arm, the sliding plate pin is fixedly connected with the rocker arm through a fastener, and the rocker arm is fixedly connected with a conversion nut. A regulating rod is connected with the conversion nut in a threaded mode. A protruding part on a guide cover at the bottom of the transmission case is inserted into a guide groove of the regulating rod. The valve assembly comprises a valve rod, a valve body, a valve seat, a valve element and a gap eliminating mechanism. According to the super-small flow regulating valve, the large linear stroke output by the executing mechanism is converted into the small valve element opening degree, so that the super-small flow resolution ratio is improved, and the super-small Kv value design of the super-small flow regulating valve is achieved.
