Abstract: The present disclosure provides a valve device having a housing and a valve core. The housing internally is provided with at least two fluid passages and sealing members located at a port of each fluid passage. The valve core is disposed in the housing and comprises at least one closing wall. The valve core is configured to be capable of rotating around an axis in a first direction in the housing to enable the closing wall to align with the corresponding fluid passage to close the aligned fluid passage. The valve core is configured to be capable of making a linear motion in a second direction in the housing to allow the closing wall to tightly abut against the sealing member at the closed fluid passage. The second direction forms an angle with an imaginary bisecting plane of the closing wall of the valve core, the angle is an acute angle. When the closing wall is aligned with the fluid passage, the imaginary bisecting plane of the closing wall is parallel to the extending direction of the part of the fluid passage near a center of the housing. In the valve device of the present disclosure, the valve core can smoothly rotate between valve core positions.
