The invention provides a pneumatic butterfly valve device, which includes main parts such as a valve, a sealing ring, a valve body, a valve stem, a bracket, a cylinder body, a rotary piston assembly, and an adjustment limit. The valve uses compressed air as a power source, and the rotary cylinder Rotate to perform opening or closing action; the valve stem is connected with the piston shaft of the rotary piston assembly through the connecting block; the valve body is integrally cast; the sealing ring is integrally pressed with high-quality rubber; the cylinder body is composed of upper and lower cylinders The body is fastened together by bolts, the cylinder body is fixed on the bracket, and the bracket is installed on the valve body; the adjustment limit can control the rotation angle of the rotary piston assembly. Compared with the prior art, the pneumatic butterfly valve device of the present invention uses compressed air as a power source, has high pressure resistance and good sealing performance, and the control process is very energy-saving and environment-friendly, effectively improves work efficiency, and can also realize automatic control.
Description
technical field [0001] The invention relates to an actuator for industrial valves, which belongs to the actuator for conveying fluid media such as air, water, and vacuum on an industrial automation assembly line, and in particular to a pneumatic butterfly valve device. Background technique [0002] The traditional butterfly valve is composed of a valve sealing part, a valve body, and an opening and closing actuator control part, which is a manual device. The valve sealing part relies on manual opening and closing to perform the action of the control part, so as to open the fluid and block the flow of the fluid. The manual opening and closing device sets the opening and closing gears to adjust the opening and closing of the valve. Due to the low precision of manual gears and lax closing, fluid leakage is caused, energy is wasted, quality problems often occur, and the environment is seriously affected. [0003] The pneumatic butterfly valve device uses compressed air as the ...
