Problems solved by technology

[0002] At present, the technology of large-diameter valves has not been fully digested in China, and imported valves are still basically used.
At the same time, large-diameter valves have large torque and difficult movements. The fork cylinder for the driving device is expensive and takes up space. In addition, the traditional fork-type cylinder can only maintain any position within the range of 90 degrees, which cannot satisfy customers in some cases. need

Abstract

The invention discloses a valve rotation driving device. The valve rotation driving device comprises an air motor, a connecting part, a gear box, a limiting switch, a bracket, a torque transmission mechanism and a valve, wherein the air motor is rigidly connected with the gear box through the connecting part; the upper part of the gear box is provided with a positioning device, and the lower part of the gear box is supported by the bracket; the valve is located beneath the bracket. For adopting the air motor as the power device, the valve rotation driving device is compact in overall structure, and capable of greatly reducing the occupied space of the device; it has very big advantage in some occasions with small space structures, and the air motor can be kept at any position; the air source pressure that the air motor can bear is greatly more than a forked type cylinder; therefore, the valve rotation driving device can greatly promote the output torque thereof and satisfy the demand of working condition.

Description

technical field [0001] The invention relates to a driving device, in particular to a valve rotation driving device. Background technique [0002] At present, the technology of large-diameter valves has not been fully digested in China, and imported valves are still basically used. At the same time, large-diameter valves have large torque and difficult movements. The fork cylinder for the driving device is expensive and takes up space. In addition, the traditional fork-type cylinder can only maintain any position within the range of 90 degrees, which cannot satisfy customers in some cases. need. Contents of the invention [0003] In order to solve the above problems and defects, the object of the present invention is to provide a valve rotation driving device. The driving device can realize parking at any position while providing high torque, and occupies a small space. [0004] In order to achieve the above object, the present invention adopts the following technical so...
