Description

Technical Field

[0001] This invention relates to the field of six-way valve technology, and in particular to a multi-mode six-way valve and a method for switching its fluid passage. Background Technology

[0002] Traditional six-way valves, based on a six-port design, are limited by their simple valve core structure and flow channel layout, enabling only 2 to 4 basic flow path modes. This makes it difficult to meet the diverse flow path combinations required by complex application scenarios. Although attempts have been made to improve flexibility by increasing the number of ports or optimizing the flow channel arrangement, these improvements are often constrained by the physical structure, and the number of achievable modes has not been effectively increased, resulting in low port utilization. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-mode six-way valve and its fluid path switching method, which can realize twelve fluid path modes and improve port utilization.

[0004] To achieve the above-mentioned objectives, the multi-mode six-way valve and its fluid path switching method of the present invention adopt the following technical solution:

[0005] A multi-mode six-way valve includes a drive assembly, a valve body, and a valve core. The valve body has a valve cavity inside, and the valve core is rotatably mounted inside the valve cavity. The drive assembly drives the valve core to rotate. The valve body has a flow channel connecting to the valve cavity, and the outer wall of the valve body has a port connecting to the flow channel. The inner wall of the valve cavity has a flow area with ten flow ports arranged in a three-row, four-column matrix, occupying the entire first row, the middle two columns of the second row, and the entire third row. There are ten flow channels and ten ports, with one end of each flow channel connected to a port and the other end connected to a flow port. The outer surface of the valve core has six inwardly recessed independent connecting cavities, which are divided into two groups along the circumference of the valve core: a first connecting cavity group and a second connecting cavity group. The first connecting cavity group includes one first connecting cavity and two second connecting cavities, and the second connecting cavity group includes one third connecting cavity. The valve core comprises a first connecting cavity and two fourth connecting cavities. The first connecting cavity is located at the upper end of the valve core and, when the valve core rotates, can simultaneously connect to a maximum of three consecutive flow ports in the first row. The third connecting cavity is located at the lower end of the valve core and, when the valve core rotates, can simultaneously connect to a maximum of three consecutive flow ports in the third row. The two second connecting cavities are located at the same axial height and are respectively located below the two ends of the first connecting cavity. The two fourth connecting cavities are located at the same axial height and are respectively located above the two ends of the third connecting cavity. When the valve core rotates, the second connecting cavity can connect to the second and third rows of flow ports in the same column, and the fourth connecting cavity can connect to the first and second rows of flow ports in the same column. The valve core body areas located between the two second connecting cavities and between the two fourth connecting cavities can block the fluid passage of two flow ports in the same column of the flow area.

[0006] Preferably, when the valve core rotates, the second connecting cavity simultaneously spans the second and third rows of flow ports in two adjacent columns of the flow area, forming a partially overlapping area with one of the flow ports in that column; the fourth connecting cavity simultaneously spans the first and second rows of flow ports in two adjacent columns of the flow area, forming a partially overlapping area with one of the flow ports in that column. This invention, through the cross-column design of the second and fourth connecting cavities, forms a variable-area overlapping area with the flow ports in two adjacent columns during rotation. By adjusting the valve core angle to continuously change the fluid flow cross-sectional area of the overlapping area, stepless adjustment of the flow rate ratio between the two columns of flow ports is achieved.

The first semi-cylindrical surface and the second semi-cylindrical surface are symmetrically distributed at 180° to each other with the valve core central axis as the boundary.

[0008] Preferably, the arrangement of the ten ports is the same as the arrangement of the ten flow ports. The ten ports are divided into three rows along the vertical direction, namely the upper row port group, the middle row port group, and the lower row port group. The upper row port group includes the fourth port A, the sixth port A, the sixth port B, and the fifth port A arranged horizontally in sequence. The middle row port group includes the first port and the second port arranged horizontally in sequence. The lower row port group includes the fourth port B, the third port A, the third port B, and the fifth port B arranged horizontally in sequence.

[0009] Preferably, the ten circulation ports include the first circulation port, the second circulation port, the third circulation port and the fourth circulation port arranged horizontally in the first row of the circulation area; the ten circulation ports also include the fifth circulation port and the sixth circulation port arranged horizontally in the second row of the circulation area; and the ten circulation ports also include the seventh circulation port, the eighth circulation port, the ninth circulation port and the tenth circulation port arranged horizontally in the third row of the circulation area.

[0010] The first flow port connects to port A (fourth port) via a flow channel; the second flow port connects to port A (sixth port) via a flow channel; the third flow port connects to port B (sixth port) via a flow channel; the fourth flow port connects to port A (fifth port) via a flow channel; the fifth flow port connects to port A (first port) via a flow channel; the sixth flow port connects to port B (second port) via a flow channel; the seventh flow port connects to port B (fourth port) via a flow channel; the eighth flow port connects to port A (third port) via a flow channel; the ninth flow port connects to port B (third port) via a flow channel; and the tenth flow port connects to port B (fifth port) via a flow channel. The port positions strictly correspond to the flow port rows and columns, simplifying the external piping layout logic and reducing assembly error rates.

[0011] Preferably, a sealing ring is provided between the valve core and the valve body, and the sealing ring has a channel that is connected to the flow port.

During operation, the first connecting cavity 4 horizontally covers a maximum of three consecutive flow ports in the first row, and the third connecting cavity 7 covers a maximum of three consecutive flow ports in the third row. The second connecting cavity 5 can vertically... The fourth connecting cavity 6 can vertically connect the first and second rows of flow ports in the same column, and can also cross the first and second rows of flow ports in two adjacent columns of the flow area, forming a partially overlapping area with the flow port in one of the columns; therefore, by controlling the rotation angle of the valve core 3, the present invention can generate twelve conflict-free flow path modes, and with the sealing ring 30 to suppress leakage, ultimately achieving twelve flow path switching within a single valve body 2.
