The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1-4, the number of the multi-way valves 100 of the thermal management module of the present invention is one or more.
The multi-way valve 100 comprises a valve body 1, a valve core 2 arranged in the valve body 1, a first sealing element 3, a second sealing element 4, a connecting flow passage 5 and a transmission shaft 6 for driving the valve core 2 to rotate.
The valve core 2 has at least one common flow passage 21 with openings arranged oppositely in the axial direction, at least one balance flow passage 22 which is not communicated with the common flow passage 21, and a support member 23. The normal flow passage 21 and the balance flow passage 22 are overlapped in axial projection and have different depths along the axial direction. In this embodiment, the depth of the common flow channel 21 is greater than the depth of the balance flow channel 22. The common flow passage 21 is used for normally passing through fluid, and the balance flow passage 22 is used for passing through fluid with the same pressure as that in the common flow passage 21, so that two sides of the valve core 2 are pressed equivalently, and the problems of inclination, large difficulty in opening the valve, easiness in abrasion and the like of the valve core 2 are avoided.
The valve body 1 comprises a valve body 11 and a valve cover 12, the valve core 2 is arranged in the valve body 11, and the valve cover 12 is used for limiting the position of the valve core 2 in the axial direction. The common flow passage 21 is disposed at a side close to the valve cap 12, and the balance flow passage 22 is disposed at a side far from the valve cap 12.
The valve body 1 is provided with a runner port 121 communicated with the common runner 21 and a balance port 122 communicated with the balance runner 22, and the runner port 121 and the balance port 122 are axially arranged on the end face of the multi-way valve 100 close to the common runner 21.
Further, the flow port opening 121 and the balance port 122 are disposed on the valve cover 12 and penetrate through the valve cover 12, and the balance port 122 is disposed radially outside the flow port opening 121.
The connection flow passage 5 is provided between the valve body 1 and the valve body 2 to communicate the balance port 122 with the balance flow passage 22. Further, the support 23 is disposed at a middle portion of an end of the valve body 2 away from the valve cover 12, so that the balance flow passage 22 is spaced apart from the valve body 11 by a distance, and the balance flow passage 22 and the connection flow passage 5 can communicate with each other.
The runner port 121, the balance port 122 and the connecting runner 5 are arranged in a circumferential array along the axis of the valve body 1. Preferably, the number of the common flow channels 21 and the number of the balance flow channels 22 are both greater than or equal to two, in this embodiment, the number of the common flow channels 21 and the number of the balance flow channels 22 are both four, and the number of the flow channel openings 121 and the number of the balance openings 122 are both eight. When the device works, the two common flow channels 21 are communicated with the two flow channel openings 121 to realize the communication effect.
In this embodiment, since the depth of the balance flow passage 22 is smaller than that of the common flow passage 21, the area of the balance port 122 may be smaller than that of the flow passage port 121, and the cross section of the connection flow passage 5 may also be smaller, so as not to increase the volume of the multi-way valve 100 too much. The equalizing port 122 and the flow port 121 communicate with each other, so that the equalizing port 122 and the flow port 121 are supplied with fluid at the same pressure.
The valve cover 12 is recessed towards one side of the valve body 11 to form a receiving portion 123, the first sealing element 3 is arranged in the receiving portion 123 of the valve cover 12, and the first sealing element 3 is abutted with the valve core 2 to isolate at least two common flow passages 21 from each other.
The second seal 4 abuts the spool 2 to isolate at least two of the balance flow passages 22 from each other.
The transmission shaft 6 is used for driving the valve core 2 to rotate, so that the common flow passage 21 is communicated with different flow passage ports 121.
In this embodiment, the common flow channel 21 is configured to communicate with at least two flow channel openings 121 to transmit fluid, and the balance flow channel 22 having a projection area coinciding with the common flow channel 21 is configured, so that when fluid is introduced into two sides of the valve core 2 at the same time, the whole force of the valve core 2 is balanced and is not prone to tilt, and thus the friction force between the valve core 2 and the first and second sealing members 3 and 4 is not increased. And the cross section of the connecting flow channel 5 is small, without increasing the excessive volume of the multi-way valve 100. The provision of the equalizing port 122 and the flow port 121 on the valve cap 12 does not interfere with the mounting of a counterpart on the other end of the multi-way valve 100.
According to the multi-way valve 100, the balance flow channel 22 and the balance port 122 are arranged, so that the valve core 2 is stressed in a balance mode when fluid is introduced, the valve core is not prone to tilting, the abrasion risk of the valve core 2 can be reduced, and the installation of a hand piece cannot be influenced.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
