Description

Technical Field

[0001] The utility model relates to the technical field of multi-way fluid valves, and in particular to a nine-way valve used in a thermal management system of a new energy vehicle. Background Art

[0002] At present, the nine-way valves of the thermal management system of new energy vehicles are mainly divided into column type and disc type. The column type nine-way valve has the problems of complex valve core structure, large flow resistance and large torque; although the disc type nine-way valve has improved some shortcomings of the column type nine-way valve, under the condition of high working pressure, its structural principle may cause material deformation, thereby affecting the compression amount of the seal, and the deformation may cause failure of the internal seal and leakage, thereby affecting the normal operation of the valve. Utility Model Content

[0003] The utility model aims to solve the above-mentioned problems and specifically designs a nine-way valve for a thermal management system of a new energy vehicle to improve the internal sealing performance of the valve and ensure its normal operation.

[0004] To achieve the above-mentioned objectives, the utility model provides a nine-way valve for a thermal management system of a new energy vehicle, comprising a main body, an actuator and a valve core rotatably installed in the main body, wherein a plurality of pipe orifices are provided in the circumference of the main body close to the valve core, the output end of the actuator drives the valve core, and the outer shell of the actuator is detachably connected to the main body through fasteners; the valve core comprises an upper flow channel and a lower flow channel arranged in sequence, the upper flow channel and the lower flow channel are both double-arc channels, the side wall of the valve core is provided with a plurality of outlets, and the outlets of the two layers of flow channels are located in the same horizontal plane; it also includes an upper cover and an inner seal with a through hole, the upper cover is fixedly connected to the valve core and closes the upper flow channel, the inner seal is a curved sealing gasket, which is installed between the main body and the valve core, and the through hole is adapted to the pipe orifice.

[0005] Furthermore, there are 9 groups of pipe openings, including the first pipe opening, the second pipe opening, the third pipe opening, the fourth pipe opening, the fifth pipe opening, the sixth pipe opening, the seventh pipe opening, the eighth pipe opening and the ninth pipe opening. The first pipe opening, the second pipe opening, the third pipe opening, the sixth pipe opening, the seventh pipe opening, the eighth pipe opening and the ninth pipe opening are all double-position pipe openings, and the fourth pipe opening and the fifth pipe opening are single-position pipe openings.

[0006] Furthermore, there are 8 groups of outlets, which are connected to the pipe openings, and the shape and size of the outlets match the flow channel.

[0007] Furthermore, the valve core is equipped with a shaft sealing ring.

[0008] Preferably, the shaft sealing ring is an X-shaped sealing ring.

[0009] Furthermore, the main body is fixedly mounted with a flange, and the flange is arranged between the actuator and the main body.

[0010] Furthermore, an external sealing gasket is installed on one side of the main body close to the pipe opening.

[0011] Furthermore, the outer wall of the main body is further provided with reinforcing ribs.

[0012] In summary, the present invention has the following advantages and beneficial technical effects:

[0013] 1. Compared with the column-type nine-way valve, the utility model is simpler, and one valve core can realize multiple working modes. This design not only simplifies the structure, but also reduces the manufacturing cost and the complexity of maintenance. Moreover, since there is only one valve core, the overall structure of the nine-way valve is more compact and efficient, which reduces the internal friction resistance, so the corresponding valve body torque will also be smaller. In addition, the design of the valve core divides the flow channel into two layers, and the outlet is located on the same layer. By reducing the height of the valve core structure, the height of the inner seal is reduced, which means that the friction path of the sealing ring during operation is reduced, thereby reducing the friction resistance. Due to the reduction in friction resistance, the inner seal can better fit the valve body, effectively solving the problem of sealing ring distortion, improving the product sealing performance and reliability, and saving maintenance costs. When the working pressure in the circuit is large (200kpa), the state of the inner seal will not change, that is, the seal will not fail.

[0014] 2. The setting of the central shaft sealing ring of the utility model is used to prevent fluid leakage at the valve core shaft and ensure the normal operation of the valve; the outer sealing gasket further ensures the sealing of the valve and prevents fluid leakage; the setting of the flange connects the valve body and the actuator to improve the overall stability and sealing performance. The flange design makes installation and disassembly more convenient.

[0015] 3. The setting of reinforcing ribs is used to increase the strength and rigidity of the main body and enhance the material's ability to resist deformation, thereby improving the overall stability and safety of the nine-way valve. BRIEF DESCRIPTION OF THE DRAWINGS
