[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] At present, my country's new energy vehicle industry is developing rapidly. Compared with fuel vehicles, the heat dissipation, heating, water circulation and other systems of new energy vehicles are highly integrated, and the pipelines are interconnected, requiring the use of multiple water valves. However, there is currently no water valve regulating mechanism that can achieve seven-channel water control and regulation. Therefore, there is an urgent need for a seven-channel water valve regulating mechanism.

[0030] During the water valve adjustment process, the valve core and sealing gasket installed inside the valve body are not tightly sealed. After a period of time, the sealing gasket will be displaced during the rotation. After the displacement, the sealing gasket will be worn, worn or compressed and permanently deformed too much, affecting its use.

[0031] The utility model provides Figures 1 to 10 A dual-axis seven-way column valve device is shown, including a valve body 1, a sealing mechanism is provided inside the valve body 1, a valve core is provided inside the sealing mechanism, the sealing mechanism is used to prevent leakage between the valve core and the valve body 1, an end cover 3 is provided at the top end of the valve body 1, a mounting hole for the valve core is provided on the end cover 3, the mounting hole is used for positioning the valve core during the installation process, an integrated actuator 2 is provided at the top end of the end cover 3, and the integrated actuator 2 is used to drive the valve core to rotate.

[0032] When in use, the sealing mechanism inside the valve body 1 is used to seal between the valve core and the valve body 1 to avoid leakage of water (fluid) between the valve core and the valve body 1 during use, which affects the use of the valve. A mounting hole for the valve core is provided on the end cover 3. The mounting hole is used to position the valve core during the installation process to avoid positional displacement of the valve core during use, resulting in uneven compression of the dynamic sealing gasket and wear of the sealing gasket. The integrated actuator 2 at the top of the end cover 3 controls the angle and position of the valve core.

[0033] The integrated actuator 2 is integrated with a control mechanism, a motor and a reduction gear system, and independently controls the rotation of the two valve cores. It can act and control independently, or it can coordinate the control of the valve core A5 and the valve core B6 to achieve different connection modes of the seven-way valve.

[0034] The valve body 1 is provided with two cavities, which are interconnected. A sealing mechanism is installed inside the cavity, and the sealing mechanism includes a sealing gasket A4 and a sealing gasket B7.

[0035] When in use, the sealing gasket A4 and the sealing gasket B7 are installed in the cavity inside the valve body 1. The valve body 1 has a large cavity and a small cavity. The sealing gasket A4 is installed in the large cavity, and the sealing gasket B7 is installed in the small cavity.

[0036] The valve core includes a valve core A5 and a valve core B6. The valve core A5 is disposed inside the sealing gasket A4, and the valve core B6 is disposed inside the sealing gasket B7.

[0037] When in use, the valve core A5 is installed inside the sealing gasket A4, and the valve core B6 is installed inside the sealing gasket B7. The cavity inside the valve body 1 is used to install the valve core A5 and the valve core B6 respectively. The large and small cavities are connected by connecting channels. There are 12 channels evenly spaced along the circumferential direction of the inner wall of the large valve cavity, of which the inlet and outlet ends of 9 channels are connected to the channel port 101 at the bottom end of the valve body 1, and 3 channels are connected to the small valve cavity. According to the mode requirements, the 2 groups of 3 channels on the outside merge into one channel at the bottom of the valve body 1.

[0038] Two channels are symmetrically arranged on both sides of the small valve cavity, and the water inlet ends of the two channels are both connected to the channel opening 101 at the bottom end of the valve body 1.

[0039] By cooperating with the corresponding rotation angles of the two valve cores, the flow section on the valve core connects the two groups of different channels on the valve body 1.

[0040] Spool A5 has two independent channels, while spool B6 has one channel. Spool B6 is always connected to a channel on spool A5. Adjusting the angle of spool A5 allows for different flow modes. Adjusting the angle of spool B6 allows for a constant flow in one channel while proportionally adjusting the flow in the other channel connected to spool B6.

[0041] Inner protrusions 403 are provided on the upper and lower sides of the interior of the sealing gasket A4 . The inner protrusions 403 are tightly fitted with the outer circumferential surface of the valve core A5 , and the outer protrusions 402 are tightly fitted with the inner wall of the valve body 1 .

[0042] When in use, the outer protrusion 402 of the sealing gasket A4 cooperates with the valve body 1 to form a seal, and the inner protrusion 403 of the sealing gasket A4 contacts the cylindrical surface of the valve core A5 to form a seal.

[0043] The inner side wall of the valve body 1 is provided with a plurality of raised limiting ribs 102 , and the outer circumferential surface of the sealing gasket A4 is provided with a plurality of grooves 401 , and the raised limiting ribs 102 are engaged with the grooves 401 of the sealing gasket A4 .

[0044] When in use, the groove 401 of the sealing gasket A cooperates with the raised limiting rib 102 of the valve body 1 to prevent the sealing gasket from falling out when rotating with the valve core. At the same time, the raised limiting rib 102 positions the sealing gasket to avoid wear of the sealing gasket during displacement. The inner cylindrical surfaces on both sides of the raised limiting rib 102 of the valve body 1 are interference fit with the protrusions 404 on the dynamic sealing gasket to form a seal.

[0045] There are 10 ribs evenly distributed inside the valve body 1, which are wedged into the groove 401 of the sealing gasket A4 to limit the sealing gasket A4 and prevent the sealing gasket A4 from moving with the valve core. The raised limiting ribs 102 of the valve body 1 can also increase the strength of the valve body 1.

[0046] A groove 401 is provided on the outside of the sealing gasket A4 and the sealing gasket B7.

[0047] The top of the raised limiting rib 102 is provided with an inclined portion 103 , and the raised limiting rib 102 fits in the groove 401 .

[0048] During use, a certain slope is set at the top of the raised limiting rib 102, so that when the dynamic sealing gasket is assembled, it can easily slide from the raised limiting rib 102 to the predetermined position with the help of the inclined portion 103 set at the top of the raised limiting rib 102. The inclined portion 103 of the raised limiting rib 102 prevents the top from cutting the dynamic sealing gasket A4, which simplifies the difficulty of assembly, saves assembly time, and the process is smooth.

[0049] The bottom end of the valve body 1 is symmetrically provided with a channel opening 101 around the outer side of the sealing gasket A4, and the channel opening 101 extends into the cavity and communicates with the valve core.

[0050] When in use, end face sealing gaskets are installed in the bottom sealing groove of the valve body 1, and the end face sealing gaskets are respectively installed on the periphery of the corresponding channel openings 101. After the valve body 1 is installed, the end face sealing gaskets are pressed by the counterpart to achieve external sealing of the inlet and outlet ends of each channel.

[0051] Channel openings 101 connect to the large and small cavities, with two sets of channels symmetrically distributed on valve core A5. Valve core A5 rotates at different angles to connect to each channel opening 101 on the valve body. Valve core B6 has only one channel, while valve core A5 has two sets of channels. Valve core A5 rotates at different angles to connect to each channel opening 101 on valve body 1, achieving different modes.

[0052] There is only one channel on the valve core B6, which can connect to one or two channels on the valve body on the small valve side by changing the angle, realizing the opening and closing and proportional changes of the two channels on the valve core B6 side. The support column on the side is not shown in the figure. It can prevent uneven shrinkage and excessive vibration of the small valve due to structural asymmetry during injection molding.

[0053] How it works

[0054] The angle and start and stop of the seven-way valve are controlled by an integrated actuator. In the actuator, the control mechanism, motor and gear train on the large and small valve sides are integrated into an assembly. The two systems can independently control the rotation of the valve core A5 and the valve core B6. The valve is integrated with two column valves, which are sensitive to adjustment and easy to control. It occupies a small space and has a low cost. It can achieve the required connection, disconnection or proportional adjustment of the flow of two groups of flow channels among the seven flow channels. One set of wiring harnesses controls two sets of mechanisms at the same time, and can realize automatic action according to the program instructions of the vehicle ECU or host computer, and accurately control the valve opening and the stop position of the valve core. After the action is completed, the water valve actuator can feedback the valve core position to the ECU or host computer.

[0055] The sealing mechanism inside the valve body 1 is used to seal between the valve core and the valve body 1 to avoid (fluid) leakage between the valve core and the valve body 1 during use, which affects the use of the valve. The end cover 3 fixes the valve core to the upper part of the valve body 1 to avoid position displacement of the valve core during use. The integrated actuator 2 at the top of the end cover 3 drives the valve core to rotate.

[0056] Sealing gasket A4 and sealing gasket B7 are installed inside the cavity inside the valve body 1. A large and a small cavity are opened inside the valve body 1. Sealing gasket A4 is installed inside the large cavity, and sealing gasket B7 is installed inside the small cavity. The outer protrusion 402 of sealing gasket A4 cooperates with the valve body 1 to form a seal. The inner side is smooth. The inner linear protrusion 403 of sealing gasket A4 increases (can reduce) the contact area with the valve core A5, (reduces torque) and improves sealing.

[0057] The sealing gasket A4 cooperates with the raised limiting rib 102 of the valve body 1, so that when the dynamic sealing gasket is assembled, it can use the inclined portion 103 set at the top of the raised limiting rib 102 to easily slide from the raised limiting rib 102 to a predetermined position. This not only increases the ease of assembly and saves assembly time, but also prevents the top of the raised limiting rib 102 from cutting the dynamic sealing gasket A4, making the assembly action simple, the process smooth, and preventing the sealing gasket from falling out.

[0058] There are 10 ribs evenly distributed inside the valve body 1, which are wedged into the groove 401 of the sealing gasket A4 to limit the sealing gasket A4 and prevent the sealing gasket A4 from moving with the valve core. The raised limiting ribs 102 of the valve body 1 can also increase the strength of the valve body 1.

[0059] Sealing gasket A4 and sealing gasket B7 are double-layer composite material structures. The inner layer is made of a material with lubricating properties and is in contact with the valve core, which is beneficial to reducing the torque of the valve. The outer layer is EPDM and is in contact with the valve body 1. After assembly, the valve body 1 cooperates with the valve core to squeeze the dynamic sealing gasket A4 and sealing gasket B7 to form a certain amount of compression, which can prevent leakage between the channels. The channel openings 101 on the sealing gasket A4 and sealing gasket B7 correspond one-to-one with the channel opening 101 on the valve body 1.

[0060] The sealing gasket A4 is provided with a groove 401 that cooperates with the raised limiting rib 102 on the valve body 1 to prevent the sealing gasket A4 from rotating with the valve core.

[0061] There is an outer protrusion 402 structure on the outer side of the sealing gasket A4, which forms a seal by pressing against the inner wall of the valve body 1.

[0062] The inner side of the sealing gasket A4 also has an inner protrusion 403 structure, which forms a sealing structure after being pressed against the valve core. At the same time, the valve core and the inner protrusion 403 of the sealing gasket A4 are in a line contact structure with a small contact area, which is beneficial to reducing the torque of the water valve.

[0063] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
