进出口可调比例三通阀和热管理系统

Abstract

一种进出口可调比例三通阀和热管理系统，涉及阀门领域，其包括阀体和阀芯，阀体设置有流体腔和均连通流体腔的三个阀口，三个阀口围绕预设轴线间隔排布；阀芯设置有连通孔，连通孔具有在其延伸方向上的第一端口和第二端口；阀芯插接于流体腔内，阀芯与阀体绕预设轴线可转动地连接，三个阀口通过连通孔连通；在阀芯转动过程中，能够使三个阀口中任意相邻两个阀口均位于第一端口所在一侧，剩余的一个阀口位于第二端口所在一侧，且阀芯能够调节位于同一侧的两个阀口中的一个阀口的流通面积。其能够灵活切换进出口以调节流体流向，且进出口调节后均能够实现入口或出口的比例调节。

Claims

The valve core (200) can adjust the flow area of ​​one of the two valve ports located on the same side.

2. The inlet and outlet adjustable proportional three-way valve according to claim 1, characterized in that: One end of the valve port penetrates the inner wall of the fluid cavity (101); The valve core (200) has an outer peripheral arc surface that fits against the inner wall surface; when the valve core (200) rotates relative to the valve body (100), the outer peripheral arc surface can pass through the corresponding valve port to adjust the area of ​​the valve port being blocked.

3. The inlet and outlet adjustable proportional three-way valve according to claim 2, characterized in that: The adjustable proportional three-way valve also includes two sealing strips, which are respectively installed on both sides of the valve core (200) in the extension direction of the preset axis, and each sealing strip is clamped between the valve core (200) and the valve body (100).

4. The inlet and outlet adjustable proportional three-way valve according to claim 3, characterized in that: The valve core (200) is provided with a positioning groove, and the sealing strip is embedded in the corresponding positioning groove.

5. The inlet and outlet adjustable proportional three-way valve according to claim 3, characterized in that: The sealing strip and the valve core (200) are vulcanized into an integral structure.

6. The inlet and outlet adjustable proportional three-way valve according to any one of claims 1-5, characterized in that: The valve core (200) has a first side (110) and a second side (120) opposite each other in the extension direction of the connecting hole (201), the first port is located on the first side (110) and the second port is located on the second side (120); both the first side (110) and the second side (120) are configured as arc surfaces.
