Abstract

The invention discloses an electric angular-travel actuator which comprises a box. A box cover is fixedly connected onto the upper portion of the box, a braking motor is arranged below the box cover, the braking motor drives a gear to rotate by a motor gear shaft, the gear drives a planet reducing mechanism to move, the planet reducing mechanism drives a shaft extension gear to rotate, a bumper pin is arranged at a position, corresponding to the shaft extension gear, on the side wall of the box, two planes fitted to the bumper pin are arranged on the shaft extension gear, and a worm is located at the side of the periphery of the shaft extension gear to form an angle of 90 DEG with the shaft extension gear. The electric angular-travel actuator is suitable for an open-loop control system and a closed-loop control system in industrial process and can precisely control a valve and an air door reliably. The electric angular-travel actuator has the advantages of small size, light weight, multifunctionality, simplicity in mounting and wiring, convenience in maintenance, attractive appearance and the like and is widely applicable to industries of metallurgy, power, petrification, water treatment and the like.

Description

technical field [0001] The invention relates to an angular stroke electric actuator for opening and closing butterfly valves, ball valves, dampers and other 90° angular stroke valves. Background technique [0002] For petroleum systems, sewage treatment, pipeline ventilation and other fields, butterfly valves, ball valves, dampers and other 90° angle-stroke valves are often used, which requires an angle-stroke electric actuator that can accurately and reliably open and close these valves. In the past, some quarter-turn electric actuators were large in size, and some functions were not comprehensive enough, which was not conducive to the installation, commissioning and maintenance of valve users on site. How to develop a quarter-stroke electric actuator with beautiful appearance and comprehensive functions has always been the goal pursued by technicians. Contents of the invention [0003] The purpose of the present invention is to provide a quarter-stroke electric actuator...
