A novel air-pressure type automatic control valve is characterized by comprising a handle, a valve core, a gland cover, a compression spring, an adjusting ring, an air inlet, an air outlet, a sealing ring, an exhaust port, a piston, an air cylinder body and a control port. The valve core of the control valve is installed on a center axis of the control valve and can move along the same; the air inlet, the air outlet and an air discharging port are formed on the valve body; the lower end of the valve body is provided with the air cylinder body; the movable piston is disposed in the air cylinder body; the control port is formed in the bottom end of the air cylinder body; the uppermost end of the control valve is provided with the compression spring; the upper end of the compression spring is provided with the gland cover; the adjusting ring is mounted on the lower end of the compression spring; the adjusting ring is fixedly connected with the valve core; the upper end of the valve core is fixedly connected with the handle; and the piston is fixedly connected with the lower end of the valve core. The novel air-pressure type automatic control valve is advantaged by great sealing effect, rational structure, automatic control and high brake efficiency; and accidents can be avoided, so the novel air-pressure type automatic control valve is safe and reliable.
