Abstract
A processing method of channels in a control valve includes steps of (1) preparing materials, which provides a valve base having a connecting portion protrudingly formed at outer periphery of a first pressure chamber, and an enlarging portion expandingly formed downward from the connecting portion; and (2) manufacturing channels, wherein a vertical channel is formed from upper portion of the connecting portion of the valve base to the enlarging portion, and a horizontal channel is formed from periphery of the first pressure chamber slantedly toward the enlarging portion. The valve base can be adjusted by adjusting a disposing angle, so that a drill head can drill slantedly from periphery of the first pressure chamber toward the enlarging portion without being interfered by an opening of the valve base, to achieve the goal of connecting the vertical channel without drilling through valve body of the valve base to assure completeness thereof.
