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.
As shown in fig. 1 to 5, the present invention provides a thermal management module having a multi-way valve 100 therein, and the number of the multi-way valves 100 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 used for driving the valve core 2 to rotate, wherein the valve core 2 is arranged in the valve body 1.
The valve core 2 has at least one through flow passage 21 axially penetrating the valve core 2, at least one horizontal flow passage 22 radially extending, a composite flow passage 23, a baffle plate 24 disposed in the composite flow passage 23, and a support 25 disposed at one axial end of the valve core 2.
The horizontal flow channel 22 includes a first flow channel 221 and a second flow channel 222 that are oppositely arranged along an axial opening, and projections of the first flow channel 221 and the second flow channel 222 in the axial direction are overlapped, in this embodiment, depths of the first flow channel 221 and the second flow channel 222 are not limited, that is, depths of the first flow channel 221 and the second flow channel 222 may be the same or different.
As shown in fig. 3, the compound flow passage 23 axially penetrates through the valve core 2, and the blocking plate 24 partially blocks the compound flow passage 23 in the radial direction. It is understood that the composite flow channel 23 is formed by communicating the horizontal flow channel 22 with the through flow channel 21. Fig. 3 shows only the through flow channel 21 and the compound flow channel 23, but in other embodiments, the through flow channel 21, the horizontal flow channel 22 and the compound flow channel 23 may be provided at the same time.
In this embodiment, the two ends of the through flow channel 21 along the axial direction of the valve element 2 are open, and the through flow channel 21 axially penetrates through the valve element 2, so that when a fluid enters the valve element 2, the pressure of the fluid inside the valve element 2 is balanced, and the problem of uneven stress on the whole valve element 2 is not caused.
When fluid is introduced into the first flow passage 221, the entire force on the valve element 2 can be balanced by introducing the same hydraulic fluid into the second flow passage 222.
Similarly, when the fluid enters the composite flow passage 23, the whole stress of the valve core 2 can still reach balance. Therefore, 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 solved.
The valve body 1 is provided with at least two runner ports 11 communicated with the through runner 21 and the horizontal runner 22.
The flow channel port 11 includes an inner flow channel port 111 and an outer flow channel port 112, the inner flow channel port 111 and the outer flow channel port 112 are disposed at one axial end of the valve body 1, and are close to one end of the first flow channel 221, and the outer flow channel port 112 is disposed at the outer side of the inner flow channel port 111 along the radial direction. In this embodiment, the number of the outer flow openings 112 is equal to that of the inner flow openings 111, and the outer flow openings and the inner flow openings are arranged in a circumferential array along the axis of the multi-way valve 100.
The inner channel opening 111 is used for communicating with the first flow channel 221 and the through flow channel 21. In this embodiment, when the first flow channel 221 communicates with at least two of the inner flow channel openings 111, the fluid enters the first flow channel 221 from one of the inner flow channel openings 111 and is discharged from the other inner flow channel openings 111.
The connecting channel 5 is used to communicate the end of the through channel 21 away from the channel opening 11 with the external channel opening 112, and to communicate the second channel 222 with the external channel opening 112. Further, the support member 25 is disposed in the middle of an end of the valve element 2 away from the port opening 11, so that the through flow passage 21 and the second flow passage 222 are spaced apart from the valve body 12 by a distance, and the through flow passage 21 and the second flow passage 222 can communicate with the connection flow passage 5.
In this embodiment, when the second flow passage 222 communicates with at least two of the external flow passages 112, the fluid enters the second flow passage 222 from one of the external flow passages 112 and is discharged from the other external flow passages 112.
When the inner channel port 111 and the outer channel port 112 communicate with the through channel 21, the fluid enters the through channel 21 from the inner channel port 111 and is discharged from the outer channel port 112 through the connecting channel 5.
The valve body 1 includes a valve body 12 and a valve cover 13, the valve cover 13 is used for limiting the position of the valve core 2 along the axial direction, and the connecting flow passage 5 is arranged between the valve body 12 and the valve cover 13.
The first flow channel 221 is disposed near the valve cover 13, and the flow channel opening 11 is disposed on the valve cover 13 and penetrates through the valve cover 13.
The valve cover 13 is recessed towards one side of the valve body 12 to form a receiving portion, the first sealing element 3 is arranged in the receiving portion, and the first sealing element 3 is abutted against the valve core 2 to isolate the through flow passage 21 and/or the first flow passage 221 from each other.
The second seal 4 abuts against the valve body 2 to isolate the through flow passage 21 and/or the second flow passage 222 from each other.
The compound flow passage 23 can simultaneously communicate with a plurality of outer flow passage openings 112 and inner flow passage openings 111.
The transmission shaft 6 is used for driving the valve core 2 to rotate, so that the through flow passage 21 and the horizontal flow passage 22 can be communicated with different flow passage ports 11.
In this embodiment, the horizontal flow channel 22 is arranged to be connected to at least two flow channel openings 11 to transmit fluid, and the first flow channel 221 and the second flow channel 222 with overlapped projection areas are arranged, so that when fluid is introduced into two sides of the valve core 2 at the same time, the overall stress of the valve core 2 is balanced, and when fluid enters the through flow channel 21, the fluid pressure inside the valve core 2 is balanced, which also does not cause the problem of uneven overall stress of the valve core 2, and is not easy to incline, and further does not increase the friction force between the valve core 2 and the first sealing element 3 and the second sealing element 4. The arrangement of the flow passage port 11 on the valve cover 13 on the same side does not affect the installation of the hand piece at the other end of the multi-way valve 100.
According to the multi-way valve 100 and the valve core 2, the through flow passage 21 and the horizontal flow passage 22 are arranged, so that the valve core 2 is stressed in a balanced manner and is not easy to incline when fluid is introduced, 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, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
