Portable valve operator

The invention belongs to the field of valve operation, and particularly relates to a portable valve operator. The right-angle speed reducing mechanism and the hollow speed reducing mechanism are arranged to carry out torque superposition speed decreasing to achieve power output, the servo motor achieves data recording and monitoring, meanwhile, over-torque protection and over-current protection in operation are provided, the mobile power source is selected to supply power to the servo motor so as to improve the adaptability of the manipulator, and the manipulator is convenient to carry, easy to operate and high in practicability. By replacing the connecting adapter, compatibility with different valves can be achieved, connection is reliable and safe, light-weight and corrosion-resistant alloy materials are selected as materials, and long-term use of the device is achieved. 本发明属于阀门操作领域，具体涉及一种便携式阀门操作器。配备直角减速机构、中空减速机构进行力矩叠加速度递减实现动力输出，伺服电机实现数据记录和监控，同时提供了操作中的过力矩保护和过电流保护，且选择移动电源为伺服电机供电以提高操作器的适应性，本操作器携带方便，易于操作，通过换取连
