Abstract
The invention discloses a three-position and three-way control valve which comprises a valve body. An upper cavity, a middle cavity and a lower cavity are formed in the valve body. Ports including A, B and C communicating with the upper cavity, the middle cavity and the lower cavity correspondingly are formed in the valve body. Seal sleeves are arranged in the upper cavity and the lower cavity correspondingly and are pressed to the corresponding valve ports under the effect of a main spring. A centre is arranged on each seal sleeve. A rotary shaft is arranged in the middle cavity. A protruding part is arranged on the rotary shaft. By rotating the rotary shaft, the protruding part on the rotary shaft is matched with the corresponding centre and overcomes the acting force of the main spring to enable the portions, at the corresponding valve ports, of the seal sleeves to be ejected open, so that the port B communicates with the port A or the port C correspondingly. A handle rotates to drive the rotary shaft connected with the handle to rotate so as to eject open the centres on the corresponding seal sleeves, and on-off of corresponding gas circuits is achieved, so that an inflating position, a pressure maintaining position and an exhausting position of a vehicle are switched stably and reliably.
