Abstract

The invention is suitable for the technical field of butterfly valves, and provides a pneumatic butterfly valve which comprises a valve body and a valve plate located in the valve body. The control mechanism is located on the valve body, and the control mechanism is connected with the valve plate through a rotating shaft; wherein the control mechanism comprises a pneumatic control module and an auxiliary control module, the auxiliary control module comprises a mounting box, at least one transmission assembly and a driving assembly used in cooperation with the transmission assemblies, and the auxiliary control module controls the working state of the valve plate in a mechanical transmission mode. The pneumatic butterfly valve is innovative in structure, and the problems that the butterfly valve cannot be controlled after the pneumatic control module is damaged, safety accidents are prone to occurring in emergency, and use is inconvenient are effectively solved.

Description

technical field [0001] The invention relates to the technical field of butterfly valves, in particular to a pneumatic butterfly valve. Background technique [0002] The pneumatic butterfly valve is composed of a pneumatic actuator and a butterfly valve. The pneumatic butterfly valve is a pneumatic valve that uses a circular butterfly plate that rotates with the valve stem to open and close to realize the activation action. It is mainly used as a cut-off valve, and it can also be designed to have the function of adjustment or section valve and adjustment. The butterfly valve operates at low pressure and large It is used more and more on medium-bore pipes. The main advantages of the pneumatic butterfly valve are simple structure, small size, light weight, and low cost. This characteristic of the pneumatic butterfly valve is particularly remarkable. It is installed in the high-altitude dark passage, and it is easy to operate through the control of the two-position five-way sol...
