Abstract
A valve device is provided. The valve device of the present invention includes a planetary component and two valve plates. The two valve plates are disposed on a hole portion of the planetary component opposite to each other, so as to provide a quick opening and closing with a relatively high opening and closing speed, and to reduce the space occupied. Therefore, the provided valve device does not need to perform adjustment (processing) to reduce the operating force on the sluice valve or to assure the closing function of the valve. Further, the function and the producibility of the valve are improved significantly.
