Description

Technical Field

[0001] The utility model belongs to the field of electronically controlled metering, and in particular relates to an electronically controlled automatic throttling metering system. Background Art

[0002] The electronically controlled automatic throttling metering equipment is also called electronically controlled flow valve. Electronically controlled flow valve is a device that adjusts the flow by adjusting the valve opening. It drives the valve opening and closing by controlling the switch of the electromagnet to achieve flow regulation. Electronically controlled flow valves are widely used in modern industry, construction, agriculture and other fields, and can be used to control the flow of various media.

[0003] At present, the Chinese utility model with the announcement number of CN220435564U discloses an electrically controlled regulating flow valve, which belongs to the technical field of flow valves, including a cavity seat, on which a motor cavity seat is arranged, and a flange ring fixed to the valve stem cavity seat of the flow valve; the flange ring is fixed to the valve stem cavity seat of the flow valve; an electrically controlled drive is installed on the inner side of the cavity seat, a circular grating scale is arranged between the electrically controlled drive and the valve stem of the flow valve, and a reading head is attached to the side of the circular grating scale; the electrically controlled drive includes a servo motor, a driving shaft is fixed on the output shaft of the servo motor; the driving shaft is installed with a small bearing; a small gear ring is fixed on the driving shaft, and the small gear ring is meshed with a large gear ring. The electrically controlled regulating flow valve of the utility model can accurately monitor whether the flow valve is adjusted in place, and the flow opening is set externally, and the controller responds roughly through the servo motor, and sends a signal to the controller through the angle detection part to drive the servo motor to accurately position.

[0004] When the servo motor of the flow valve is stopped and not running, even if the servo motor is a motor with a shutdown self-locking function, when the motor is out of power for too long, the locking force of the motor will gradually decrease. When the motor locking force is not enough to overcome the shear force, it will not be able to maintain the self-locking state, thereby reducing the service life of the flow valve. At the same time, the valve is not convenient for internal inspection and maintenance. Utility Model Content
