The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
Next, referring to the drawings, a multi-way valve 100 according to an embodiment of the present invention is described.
As shown in fig. 1 to 7, a multiway valve 100 according to an embodiment of the present invention includes: a housing 1 and a valve core 2, wherein the housing 1 is provided with at least three through holes; the valve core 2 is rotatably arranged in the shell 1, the valve core 2 is provided with a plurality of switching flow passages, the plurality of switching flow passages comprise a first switching flow passage 21 and a second switching flow passage 22, and the first switching flow passage 21 is configured so that one of the through holes is in switching communication with at least two through holes; the second switching flow passage 22 is configured such that different communication holes are switched to communicate, and the second switching flow passage 22 is also configured such that the number of communication holes that communicate can be changed.
Therefore, the multi-way valve 100 can have both reversing function and proportion adjusting function, realizes integrated arrangement, reduces the number of driving parts 4, is beneficial to reducing cost, saves installation space, and can realize the purpose of continuous flow.
For example, referring to fig. 1 to 5, the multi-way valve 100 includes a housing 1 and a valve cartridge 2, an open fitting chamber is formed in the housing 1, the valve cartridge 2 is mounted to the fitting chamber, and a cover plate 5 is detachably mounted to the housing for closing the open end of the fitting chamber, thereby sealing the valve cartridge 2 in the housing 1. The valve core 2 is arranged to be rotatable relative to the shell 1, the shell 1 is also provided with a driving piece 4, and the output end of the driving piece 4 is connected with the valve core 2, so that the driving piece 4 can drive the valve core 2 to rotate around the axis of the valve core.
The side wall of the assembly cavity of the shell 1 is provided with at least three through holes which are arranged at intervals along the radial direction of the valve core 2 and are opposite to the valve core 2 and communicated with a flow passage for circulating medium. The spool 2 is provided with a plurality of switching flow passages including a first switching flow passage 21 configured such that one of the through-holes is in switching communication with at least two through-holes, and a second switching flow passage 22 configured such that different through-holes are in switching communication, the second switching flow passage 22 also being configured to vary the number of through-holes that are in communication. It should be noted that, by switching the flow channels through different flow through holes, the function of the multi-way valve reversing valve can be realized, so that the thermal management module with the multi-way valve reversing valve can perform mode switching.
For example, as shown in fig. 4 to 7, the circulation through holes may be provided to include a first circulation through hole 111, a second circulation through hole 112, a third circulation through hole 113, a fourth circulation through hole 121, and a fifth circulation through hole 122. The first switching flow path 21 may be used to communicate the second flow passage 112 with the first flow passage 111, or may be used to communicate the second flow passage 112 with the third flow passage 113. Since the second communication hole 112 is always provided with a communication hole communicated with the second communication hole during the rotation of the valve body 2 to perform the mode switching, the purpose of continuous flow of the multi-way valve 100 can be achieved, and the pipe connected with the multi-way valve always has liquid flow. In the process of rotating the valve element, the valve element may be in switching communication with at least a plurality of through holes through different through holes, for example, the first switching flow passage 21 may correspond to four or more through holes, the flow passage may be switched between the first through hole 111 and the third through hole 113 through the second through hole 112, and then may be in switching communication with the fourth through hole 121 and the fifth through hole 122 through the third through hole 113, so that the purpose of reversing the multi-way valve 100 is ensured.
The second switching flow passage 22 may be used to communicate the fourth flow through hole 121 with the third flow through hole 113, or may be used to communicate the fifth flow through hole 122 with the third flow through hole 113. The second switching flow passage 22 may be used to communicate two flow holes, and may be used to communicate the fourth flow hole 121 and the fifth flow hole 122 with the third flow hole 113, respectively. Alternatively, the second switching flow passage may be configured to communicate with three or more through-holes, whereby the number of through-holes to be communicated is changed.
In the process of switching the second switching flow passage 22 from communication with the fourth through-hole 121 to communication with the fifth through-hole 122, the second switching flow passage 22 is simultaneously communicated with the fourth through-hole 121 and the fifth through-hole 122 and then is separately communicated with the fifth through-hole 122 as the valve body 2 rotates. In the process of simultaneously communicating the second switching flow passage 22 with the fourth flow through hole 121 and the fifth flow through hole 122, the area of the second switching flow passage 22 communicating with the fourth flow through hole 121 may be gradually reduced along with the rotation of the valve element 2, so that the area of the second switching flow passage 22 communicating with the fifth flow through hole 122 is gradually increased, and vice versa. Therefore, the proportion adjusting function can be realized, and the purpose of continuous flow in the proportion adjusting process can be realized.
The above-described embodiments are merely exemplary, and do not limit the present application, and the present application may also provide six through holes or more, and the present application is not limited thereto.
According to the multi-way valve 100 of the embodiment of the invention, one through hole and at least two through holes can be switched and communicated by arranging the first switching flow passage 21, and different through holes can be switched and communicated by arranging the second switching flow passage 22, and the number of the communicated through holes can be changed, so that the multi-way valve 100 can have both a reversing function and a proportion adjusting function, realize integrated arrangement, reduce the number of driving parts 4, facilitate reducing cost, save installation space and realize the purpose of continuous flow.
In some embodiments of the present invention, the first switching flow passage 21 extends in the rotation direction of the spool 2, and the plurality of through-holes are sequentially arranged in the extending direction of the first switching flow passage 21.
For example, referring to fig. 3, a first switching flow passage 21 is provided on the outer peripheral wall of the spool 2, the first switching flow passage 21 being arranged to extend in the rotational direction of the spool 2. The casing 1 has a plurality of through holes sequentially arranged in the extending direction of the first switching flow passage 21, the first switching flow passage 21 is used for communicating two (or more of course) adjacent through holes, and when the valve element 2 rotates, the first switching flow passage 21 can communicate the through holes with another adjacent through hole.
In a practical arrangement, as shown in fig. 4 to 7, the first through-hole 111, the second through-hole 112, and the third through-hole 113 may be arranged in this order, and when the first switching flow passage 21 communicates the first through-hole 111 and the second through-hole 112, the spool 2 may be rotated so that the first switching flow passage 21 may communicate the second through-hole 112 and the third through-hole 113, and vice versa. Thereby, the switching stability of the first switching flow path 21 is advantageously improved, and the reliability of the multi-way valve 100 is improved.
In some embodiments of the present invention, the housing 1 is provided with at least two rows of through-hole groups arranged in the direction in which the central axis of the valve spool 2 extends, each of the rows of through-hole groups including a plurality of through-holes arranged in the direction of rotation of the valve spool 2, the at least two rows of through-hole groups including a first row of through-hole groups 11 and a second row of through-hole groups 12, at least two through-holes in the first row of through-hole groups 11 being in switching communication by a first switching flow passage 21, and the second switching flow passage 22 being configured to communicate the through-holes in the first row of through-hole groups 11 and the second row of through-hole groups 12.
For example, referring to fig. 2 to 4, the housing 1 may be provided with at least two rows of through-hole groups, which are sequentially arranged along the central axis extending direction of the valve element 2, each row of through-hole groups including a plurality of through-holes, and the plurality of through-holes of the same group may be sequentially arranged along the rotation direction of the valve element 2. Wherein the at least two rows of through-hole groups include a first row of through-hole groups 11 and a second row of through-hole groups 12, at least two of the through-holes in the first row of through-hole groups 11 are switched in communication by a first switching flow passage 21, and a second switching flow passage 22 is configured for communicating the through-holes of the first row of through-hole groups 11 and the second row of through-hole groups 12.
For example, as shown in fig. 4 to 7, the first row of through-hole groups 11 may be provided to include the first through-hole 111, the second through-hole 112, and the third through-hole 113, the first through-hole 111, the second through-hole 112, and the third through-hole 113 being sequentially arranged in the rotation direction of the spool 2, the second row of through-hole groups 12 including the fourth through-hole 121 and the fifth through-hole 122, the fourth through-hole 121 and the fifth through-hole 122 being sequentially arranged in the rotation direction of the spool 2.
The first switching flow path 21 may communicate the first flow passage 111 with the second flow passage 112, or may communicate the second flow passage 112 with the third flow passage 113. The second switching flow passage 22 may communicate the fourth flow through hole 121 with the third flow through hole 113, may communicate both the fourth flow through hole 121 and the fifth flow through hole 122 with the third flow through hole 113, and may communicate the fifth flow through hole 122 with the third flow through hole 113. The above embodiments are merely exemplary and do not limit the present invention.
Through the arrangement, the valve core 2 can communicate the circulation through holes of different through hole groups, so that the arrangement of the circulation through holes can be flexible, the practicability of the multi-way valve 100 is improved, and the layout difficulty of the multi-way valve 100 is reduced.
In some embodiments of the present invention, the second switching flow passage 22 is disposed in the valve core 2, the second switching flow passage 22 is provided with at least one first communication hole 221 and a plurality of second communication holes 222, the first communication hole 221 is in communication with or offset from the first row of through hole groups 11, and the second communication hole 222 is in communication with or offset from the second row of through hole groups 12.
For example, referring to fig. 2 to 4, the second switching flow passage 22 is provided in the valve body 2 and is spaced apart from the first switching flow passage 21, and a communication hole is formed in the side wall of the valve body 2 corresponding to the second switching flow passage 22, and the communication hole penetrates the side wall of the valve body 2 in the radial direction of the valve body 2. The second switching flow passage 22 is provided with at least one first communication hole 221 and a plurality of second communication holes 222, and the first communication holes 221 and the second communication holes 222 are arranged in order in the axial direction of the spool 2. The first through holes 221 are disposed opposite to the first row of through holes 11, and the first through holes 221 may be communicated with or staggered with the through holes of the first row of through holes 11; the second communication holes 222 are disposed opposite to the second row of through holes 12, and the second communication holes 222 may be in communication with or offset from the through holes of the second row of through holes 12.
It can be appreciated that by providing the first row of through holes 11 and the second row of through holes 12 that can be respectively communicated with the second switching flow channel 22 through different communication holes, the situation that the first row of through holes 11 and the second row of through holes 12 are directly communicated can be avoided, which is beneficial to improving the flow stability of the liquid in the second switching flow channel 22 and improving the reliability of the multi-way valve 100. Further, by arranging the second switching flow passage 22 inside the valve element 2, the internal space of the valve element 2 can be reasonably utilized, and the flexibility of the shape setting of the second switching flow passage 22 can be increased.
In some embodiments of the present invention, the first communication hole 221 is configured to communicate with at least two communication holes at the same time, and the second switching flow passage 22 communicates with one of the communication holes through the second communication hole 222. That is, when the second communication hole 222 rotates to be blocked by the housing 1 without fluid inflow during rotation of the valve body 2, the first communication hole 221 may also have a communication hole communicating therewith, so that the first communication hole 221 may be switched to communicate with a different communication hole on the housing 1 through the second switching flow passage 22 and the second communication hole 222, and the number of the communication fluid holes may also be changed. Thereby, the structure of the valve element 2 is made simple.
In some embodiments of the present invention, as shown in fig. 3, the extension length of the first communication hole 221 in the circumferential direction of the spool 2 is at least twice the extension length of the second communication hole 222.
In some embodiments of the present invention, for example, referring to fig. 3, in the rotational direction of the spool 2, both sides of the first switching flow path 21 are provided with first communication holes 221. With the above arrangement, the first row of through holes 11 always have the through holes in communication with the first switching flow passage 21 and/or the first through holes 221 during rotation of the spool 2, so that the purpose of continuous flow can be achieved.
For example, as shown in fig. 4 to 7, the first row of through-hole groups 11 may be provided to include a first through-hole 111, a second through-hole 112, and a third through-hole 113, the first through-hole 111, the second through-hole 112, and the third through-hole 113 being sequentially arranged in the circumferential direction of the spool 2, the first switching flow passage 21 being configured to communicate adjacent two of the first through-hole 111, the second through-hole 112, and the third through-hole 113, and the first through-holes 221 may be provided on both sides of the first switching flow passage 21, respectively, in the rotational direction of the spool 2. When the first switching flow passage 21 communicates the first communication hole 111 and the second communication hole 112, the corresponding-side first communication hole 221 may communicate with the third communication hole 113, and when the first switching flow passage 21 communicates the second communication hole 112 and the third communication hole 113, the corresponding-side first communication hole 221 may communicate with the first communication hole 111.
In some embodiments of the present invention, the first communication hole 221 and/or the first switching flow passage 21 are disposed directly opposite to the at least one second communication hole 222 in the extending direction of the central axis of the spool 2. For example, as shown in fig. 3, the first communication hole 221 may be provided so as to face the at least one second communication hole 222 in the extending direction of the central axis of the valve body 2; or the first switching flow passage 21 may be provided so as to be disposed opposite to the at least one second communication hole 222; alternatively, the first communication hole 221 and the first switching flow path 21 may be provided so as to face the at least one second communication hole 222. Through the above arrangement, concentrated arrangement is realized, which is beneficial to reducing the size of the multi-way valve 100, and further reducing the overall size of the multi-way valve 100.
In some embodiments of the present invention, the second communication hole 222, which is disposed opposite to each of the first communication holes 221, is located at an end of the corresponding first communication hole 221 facing away from the first switching flow path 21. For example, referring to fig. 3, in the extending direction of the central axis of the valve body 2, each of the first communication holes 221 is held in opposition to one of the second communication holes 222, and the second communication hole 222 in opposition to the first communication hole 221 is located at an end of the first communication hole 221 facing away from the first switching flow passage 21. Thus, when the second communication hole 222 facing the first communication hole 221 is offset from the communication hole of the second row of through holes 12, the first communication hole 221 can still communicate with the same communication hole of the first row of through holes 11. Thus, the communication between the first communication hole 221 and the different communication holes in the second row of through-hole groups 12 can be realized, which is advantageous for improving the practicality of the multi-way valve 100.
Further, referring to fig. 3, in the extending direction of the central axis of the valve body 2, both ends of the first switching flow passage 21 are provided with one second communication hole 222 facing each other. For example, as shown in fig. 4 to 5, when the first switching flow passage 21 communicates with the first and second flow through holes 111, 112, the first communication hole 221 located on the right side may communicate with the third flow through hole 113.
