The invention discloses a pneumatic control valve which comprises a main valve body and a pneumatic executing mechanism. The main valve body comprises a front valve body, a middle valve body and a rear valve body which are coaxially arranged and communicate with one another; the middle valve body is arranged in the front valve body and close to the rear valve body; a valve clack seat is arranged on the side, close to the middle valve body, of the rear valve body; a valve clack piece is arranged on the valve clack seat; the pneumatic executing mechanism comprises a hollow valve element and an elastic piece; the hollow valve element is coaxially arranged in the main valve body; the outer wall of the hollow valve element is in sliding connection with the inner wall of the front valve body and the inner wall of the middle valve body; the elastic piece is arranged on the hollow valve element in a sleeving mode and makes contact with the front valve body; the hollow valve element is pressed on the valve clack piece under the action of the elastic piece; an air source connector is arranged on the front valve body; and high-pressure air is introduced into the air source connector, and drives the hollow valve element to move and be separated from the valve clack piece. According to the pneumatic control valve provided by the invention, the main valve body and the pneumatic executing mechanism are integrated, so that the structure is compact, and the pneumatic control valve can be used in a small space.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a pneumatic control valve. Background technique [0002] Pneumatic valve is a valve driven by compressed air to realize switching, which is suitable for controlling gas, steam, liquid and other media. The current pneumatic valve structure is that the actuator and the valve are separated, and the middle is connected by a transmission mechanism. For example, a pneumatic valve control mechanism disclosed in the patent No. CN109538787A, the pneumatic valve includes: a valve body and its upper bonnet, valve core , the valve shaft; the valve core is provided with a channel; it includes a rotary cylinder, a cylinder-driven actuator, a sealing control mechanism, and a valve core action position detection mechanism; the outer walls of the two ports of the valve core are respectively provided with sealing grooves along the circumferential direction, and the sealing grooves An inflatable se...
