The invention discloses a manual valve-operating mechanism driven by a cylindrical gear, which comprises an input shaft, a handwheel assembly is arranged on one end of the input shaft, and a transmission gear is fixed on the other end of the input shaft; the transmission gear is engaged with the cylindrical gear, and can drive the cylindrical gear to rotate; a worm is fixed on the cylindrical gear, and can rotate along with the cylindrical gear; the worm is connected with a worm gear; and a valve connector is arranged on the worm gear, and is used for connection with a valve to be operated, so that the service state of the valve can be controlled by rotating the handwheel assembly. When the manual valve-operating mechanism is in use, by means of the transmission of the transmission gear and the cylindrical gear, the transmission ratio on the input shaft driven by the handwheel assembly to rotate can be decreased and transmitted to the valve connector arranged on the worm gear, consequently, the valve can be accurately controlled, and thereby the functions of finely adjusting and accurately controlling the operated valve can be achieved.
Description
technical field [0001] The invention relates to a valve control device, in particular to a cylindrical gear-driven valve manual device capable of fine-tuning and precisely controlling the valve. Background technique [0002] General valve control needs to be done manually. When the valve is manually controlled, it is easy to control the switch. However, when the valve size needs to be adjusted, errors often occur in manual control, and the fluctuation of the adjustment is relatively large. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a valve manual device with cylindrical gear transmission that can realize fine adjustment and precise control of the valve. [0004] The technical solution of the present invention is realized as follows: a valve manual device driven by a cylindrical gear, including an input shaft, one end of the input shaft is provided with a handwheel assembly, and the...
