More Information
Summary:The utility model relates to the technical field of pneumatic actuators, in particular to a novel pneumatic actuator for a regulating valve, which comprises a shell, a first pneumatic actuator, a second pneumatic actuator and a third pneumatic actuator. The piston is located in the shell, the piston is connected with the tooth column in a meshed mode, and the piston is used for being stressed to move towards the outer side so that the tooth column can be stressed to rotate; the driving shafts are fixedly connected with the pistons, the driving shafts are used for being pushed by the pistons to move transversely, the driving shafts are additionally arranged on the two sides of the device, the pistons are pushed by air pressure to move towards the two sides, the rotating shaft at the bottom can be driven to rotate through the tooth columns, and transverse movement power can be provided for the external driving shafts; the device is not only suitable for a plurality of different regulating valves, but also saves
