Abstract

Disclosed is a two-way air control valve, comprising a valve body (10) and an air cylinder (20), wherein the valve body (10) is provided with an inlet (11), an outlet (12) and a movable valve core (13); the air cylinder (20) is internally provided with a slidable piston (21); the centre of the piston (21) is connected with a piston rod (22) capable of pressing the valve core (13) to move to open / close a channel arranged between the inlet (11) and the outlet (12); and the outer wall of the air cylinder (20) is provided with an air control interface (23). The two-way air control valve is characterized in that a spacer bush (30) is sheathed between the air cylinder (20) and the piston rod (22), and one side of the spacer bush (30) is fixedly connected to the valve body (10) and the other side of the spacer bush (30) is rotatably connected to the air cylinder (20). The air cylinder portion of the two-way air control valve is rotatable and provides convenience in installation for a client during usage, and the service life of a sealing gasket is prolonged.
