Abstract
Official abstract text for this publication.
A pneumatic control valve includes a first valve body, a pushing block, a rotating block, a second valve body, an end cover, and a piston. The first valve body defines a first gas inlet and a receiving hole. The first valve body forms a plurality of guiding ribs evenly positioned on the inner surface of the receiving hole away from the first gas inlet, and each of the guiding ribs forms an inclined surface at a distal end thereof. The pushing block and the rotating block are slidably received in the receiving hole. The second valve body is connected to an end of the first valve body adjacent to the receiving hole of the first valve body. The end cover is fastened on an end of the second valve body away from the first valve body. A pneumatic control system using the pneumatic control valve is also provided.
