- Multi-way valves are widely used in the thermal management system of electric vehicles to switch pipelines.
- the present application provides a multi-way valve to address the above technical issues.
- a multi-way valve comprising: a valve body, the valve body being constructed with at least one first opening and at least one second opening; a valve core, the valve core being installed in the valve body and being able to rotate around its own axis in the valve body, the valve core being provided with a first channel and a connecting port, the connecting port being connected to the first channel; wherein the first channel is always connected to at least one of the first openings, and when the valve core is rotated to a mode in which the connecting port and the second opening are connected, the connecting port is connected to at least one of the second openings.

- FIG2 is a three-dimensional view from another angle of one embodiment of the multi-way valve provided in the present application.
- FIG5 is a schematic structural diagram of a valve core at another angle of one embodiment of the multi-way valve provided in the present application.
- FIG15 is a flow rate variation table of the multi-way valve provided in the present application when the valve core is at different rotation angles.
- first feature when a first feature is “above” or “below” a second feature, it can mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediary. Furthermore, when a first feature is “above,” “above,” or “above” a second feature, it can mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is higher in level than the second feature. When a first feature is “below,” “below,” or “below” a second feature, it can mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is lower in level than the second feature.
- first opening 11 and the second opening 12 are spaced apart in the axial direction of the valve body 10, and the valve core 20 and the first opening 11 are located at different axial positions of the valve body 10. In this way, the rotation of the valve core 20 does not affect the first opening 11, ensuring that the first opening 11 is always open and the first channel 21 is always connected to one of the first openings 11.
- the communication port includes a second communication port 212, and there are two second openings 12.
- the second communication port 212 can communicate with both second openings 12, and the first opening 11 can communicate with both second openings 12.
- the medium can flow into the valve body 10 from the first opening 11 and flow out of the two second openings 12 through the second communication port 212.
- the specific process is as follows: the second communication port 212 can first partially communicate with at least one second opening 12, then fully communicate, and then, as the valve core 20 further rotates, communicate with two adjacent second openings 12.
- the first opening 11 serves as inlet A
- the two second openings 12 are outlets B and C respectively.
- the flow of inlet A is equal to that of outlet B in the initial state (see Figure 13); thereafter, part of the flow of inlet A flows out from outlet B, and the other part flows out from outlet C.
- the valve core 20 has a large rotation angle range. As the valve core 20 rotates, the flow curves of the two second openings 12 change smoothly, and there will be no exponential mutation of the flow.
- the communication port also includes a third communication port 213.
- the third communication port 213 can partially communicate with at least one second opening 12, then fully communicate, and then communicate with two adjacent second openings 12.
- medium can enter the first channel 21 through the first opening 11 and then flow out of the second opening 12 through the third communication port 213.
- the third communication port 213 communicates with two second openings 12, with the first opening 11 serving as the inlet, medium can enter the first channel 21 through the first opening 11 and then flow out of each second opening 12 through the third communication port 213.
- Rotating the valve core 20 adjusts the conduction area between the two second openings 12 and the third communication port 213, achieving precise regulation of the flow rate of the two second openings 12.
- the valve core rotates in a wide angle range, and the flow curves of the two second openings 12 change smoothly.
- the third communication port 213 cooperates with the second communication port 212 to increase the range of conduction mode adjustment of the valve core 20.
- the sealing gasket 30 improves the sealing performance between the valve core 20 and the valve body 10, preventing leakage of the medium.
- the cutout 31 of the sealing gasket 30 can prevent the sealing gasket 30 from affecting the communication between the valve core 20 and the first opening 11 and/or the second opening 12 .
- the sealing gasket 30 there are two cutouts 31, each of which communicates with a corresponding second opening 12.
- one side of the sealing gasket 30 in the thickness direction serves as the inner circumference of the sealing gasket 30.
- the outer circumference of the valve core 20 abuts the inner circumference of the sealing gasket 30.
- the second communication port 212, the third communication port 213, and the fourth communication port 221 each communicate with the cutout 31 and, in turn, communicate through the second opening 12 corresponding to the cutout 31. Fluid passing through the cutout 31 can only flow through the second opening 12 directly opposite it, ensuring accurate flow at each second opening 12 and preventing internal leakage.
- the outer circumference of the gasket 30 is defined by its other side in the thickness direction. This outer circumference is provided with a plurality of ribs 32 arranged in an array and connected to the valve body 10.
- the ribs 32 reduce the contact area between the gasket 30 and the valve body 10, thereby increasing the pressure per unit area and thereby improving the tightness and strength of the connection. This ensures a stable position and prevents positional shifting due to friction with the rotating valve core 20, while also enhancing sealing performance.

- the second opening 12 serves as the water outlet
- the first opening 11 and the first channel 21 are always connected through the first connecting port 211

- the first opening 11 communicates with the first channel 21 via the first communication port 211, and the third communication port 213 communicates with two adjacent second openings 12.
- the position of the third communication port 213 rotates from communicating with only one second opening 12 to communicating with both adjacent second openings 12.
- the communication area of the second opening 12 that first communicates with the third communication port 213 gradually decreases, while the communication area of the second opening 12 that later communicates with the third communication port 213 gradually increases.
- the black area represents the area through which the medium can flow
- the light gray area represents the sealing gasket 30
- the off-white area represents the cutouts 31 formed in the sealing gasket 30, namely, the two cutouts 31 that can communicate with the two second openings 12.

- At least one second opening 12 functions as a water inlet
- at least one second opening 12 functions as a water outlet
- the second channel 22 is in communication with both the water inlet and the water outlet. That is, as the valve core 20 rotates further, the second communication port 212 and the third communication port 213 both rotate to positions where they are no longer in communication with the second opening 12. Fluid flowing into the second and third communication ports 212 and 213 through the first opening 11 is unable to flow out through the second opening 12.
- the first opening 11 functions neither as a water inlet nor as a water outlet. Instead, one of the two second openings 12 functions as a water inlet, and the other functions as a water outlet.

- the positions of the second communication port 212 and the third communication port 213 are symmetrical with respect to the center line of the valve core, and the structures and technical effects of the two are the same. Therefore, in other embodiments, the positions of the second communication port 212 and the third communication port 213 can also be interchanged, and are not limited to the above-mentioned embodiment in which the first cavity 214 and the second communication port 212 correspond to each other.

- the second channel 22 communicates with at least two second openings 12 via the fourth communication port 221. This ensures the implementation of the sixth conduction mode.
- the fourth communication port 221 allows the medium in the second opening 12 to enter the second channel 22 and then exit through another second opening 12, achieving pipeline switching. The presence of this port on the sidewall allows the valve core 20 to directly face and connect the fourth communication port 221 to the second opening 12 with a simple rotation.

- the first partition plate 27 is located between the first sector 23 and the fourth sector 26, and the second partition plate 28 is located between the third sector 25 and the fourth sector 26. In this way, the first partition plate 27 ensures that the medium between the first sector 23 and the fourth sector 26 is isolated, preventing the mixing of the medium when only the first channel 21 or the second channel 22 is opened.
- the second partition plate 28 ensures that the medium between the third sector 25 and the fourth sector 26 is isolated.
- the dividing block 29 separates the first sector 23 and the third sector 25 so that both can independently communicate with the second opening 12.

请参见图1-图3,多通阀100包括阀体10和阀芯20,阀体10构造有至少一个第一开口11和至少一个第二开口12,阀芯20安装于阀体10中,并能够在阀体10中绕着自身轴线转动,在本实施例中,阀芯20以及阀体10的至少部分设置为圆形,因此阀芯20能够在阀体10中自由转动而不产生干涉,且在本实施例中阀芯20和阀体10同轴设置,也就是说阀芯20绕着阀体10的轴线转动。
请参见图4-图6,阀芯20中开设有第一通道21和连通口,连通口与第一通道21连通;其中,第一通道21始终与一个第一开口11连通,当阀芯20转动到连通口与第二开口12连通的模式下,连通口与至少一个第二开口12连通。如此,第一连通口211始终与第一开口11连通,因此第一通道21始终能够与第一开口11实现介质的流通,介质能够从第一开口11流入第一通道21内,也能够从第一通道21内流出第一开口11。第一通道21始终能够与第一开口11实现介质的流通,有助于在多通阀100的导通模式调整的过程中,简化了阀体10与阀芯20结构。
进一步地,第一开口11和第二开口12于阀体10的轴向间隔设置,阀芯20和第一开口11位于阀体10的轴向的不同位置。如此,阀芯20的转动不影响第一开口11,保证第一开口11始终处于敞口状态,保证第一通道21始终与一个第一开口11连通。
在本实施例中,连通口包括第二连通口212,第二开口12的数量为两个,随着阀芯20的转动,第二连通口212能够与两个第二开口12均连通,第一开口11能够与两第二开口12均连通,也就是说介质能够从第一开口11处流入阀体10,并通过第二连通口212流出两个第二开口12。具体的过程为:第二连通口212能够先与至少一个第二开口12部分连通,再全部连通,之后随着阀芯20的进一步旋转与相邻的两个第二开口12连通。当第二连通口212与一个第二开口12连通时,第一开口11作为进口时,介质能够通过第一开口11进入第一通道21,再经由第二连通口212从第二开口12流出。当第二连通口212与两个第二开口12连通时,第一开口11作为进口时,介质能够通过第一开口11进入第一通道21,再经由第二连通口212分别从第二开口12流出,转动阀芯20,调整两个第二开口12分别与第二连通口212导通面积,实现两个第二开口12流量的精准调节。
请参见图13-图15,第一开口11作为进口A,两个第二开口12分别为出口B与出口C,进口A的流量在初始状态下与出口B相等(参见图13);之后进口A的流量一部分从出口B流出,另一部分从出口C流出,在进行两个第二开口12流量调节的全过程中,阀芯20转动角度范围大,随着阀芯20的转动,两个第二开口12的流量曲线变化平滑,不会出现流量的指数型突变。
连通口还包括第三连通口213,随着阀芯20的进一步转动,当阀芯20转动到第三连通口213与第二开口12连通的模式下,第二连通口212转动到与第二开口12无法连通的位置,此时第三连通口213能够与至少一个第二开口12部分连通,再全部连通,之后与相邻的两个第二开口12连通。当第三连通口213与一个第二开口12连通时,第一开口11作为进口时,介质能够通过第一开口11进入第一通道21,再经由第三连通口213从第二开口12流出。当第三连通口213与两个第二开口12连通时,第一开口11作为进口时,介质能够通过第一开口11进入第一通道21,再经由第三连通口213分别从第二开口12流出,转动阀芯20,调整两个第二开口12分别与第三连通口213导通面积,实现两个第二开口12流量的精准调节。在进行两个第二开口12流量调节的全过程中,阀芯转动角度范围大,两个第二开口12的流量曲线变化平滑。第三连通口213与第二连通口212相配合,增加了阀芯20可进行导通模式调整的范围。
多通阀100包括密封垫30,密封垫30位于阀芯20与阀体10内壁之间,并与阀体10连接,阀芯20的外周侧与密封垫30朝向阀芯20的一侧抵接,密封垫30上开设有与第二开口12正对的切口31。第一开口11、密封垫30于阀体10的轴线方向的投影间隔设置。第一开口11位于阀体10与密封垫30对应的区域外。即阀体10的第一开口11处无需设置密封垫30,至少部分密封垫30位于第一开口11与第二开口12之间。密封垫30厚度方向的一侧表面与阀芯20的表面接触并密封配合,且密封垫30的厚度方向的另一侧表面密封连接于阀体10的内表面。因此,流体难以在阀芯20和阀体10的连接处发生泄漏。密封垫30能够提高阀芯20与阀体10之间的密封性能,防止介质泄漏。密封垫30的切口31能够避免密封垫30影响到阀芯20与第一开口11和/或第二开口12之间的连通。
具体地,切口31为两个且每一个切口31对应与一个第二开口12连通,如此,密封垫30厚度方向的一侧表面为密封垫30的内周侧。阀芯20的外周侧与密封垫30的内周侧相抵接,随着阀芯20的转动,第二连通口212、第三连通口213和第四连通口221分别实现与切口31连通,并分别通过与该切口31对应的第二开口12实现连通。经切口31的流体只能从与其正对的第二开口12流过,保证每一第二开口12流量的精准性,避免内漏。
密封垫30的厚度方向的另一侧为外周侧,外周侧设置有多根凸筋32,凸筋32呈阵列布设并且与阀体10连接。凸筋32能够减少密封垫30与阀体10之间的接触面积,以提高单位面积压强,从而提高连接紧密性和连接强度,确保自身位置稳定,不会因为与转动的阀芯20的抵接摩擦过程中出现位置偏移,同时也提高了密封性能。
多通阀100具有多种导通模式,包括第一导通模式、第二导通模式、第三导通模式、第四导通模式、第五导通模式和第六导通模式,前五种导通模式下,多通阀100通过第一通道21与第二开口12连通,在第六导通模式下,多通阀100通过第二通道22与第二开口12连通。多通阀100通过阀芯20的转动在多个导通模式之间切换,在此对于各个导通模式一一详细阐述:
当多通阀100处于第一导通模式下,第一开口11作为进水口,第二开口12为出水口,第一开口11与第一通道21导通,第二连通口212与一个第二开口12导通。如此,随着阀芯20的转动,第二连通口212与第二开口12的导通面积逐渐增大,直到第二连通口212和第二开口12完全导通,此时第二连通口212和一个第二开口12之间的流通面积达到最大。或者,第二连通口212与第二开口12的导通面积由面积最大到逐渐减小。介质的流动路径为,从第一开口11进入,通过第一连通口211进入第一通道21,再从第二连通口212通过第二开口12流出。
当多通阀100处于第二导通模式下,第一开口11依然作为进水口,第二开口12作为出水口,第一开口11与第一通道21通过第一连通口211始终处于导通,第二连通口212与相邻的两个第二开口12导通,也就是说第二连通口212的部分与一个第二开口12中的部分连通,第二开口12中的另一部分与一个第二开口12中的部分连通。随着阀芯20的转动,第二连通口212首先与一个第二开口12连通,进入第一导通模式,阀芯20进一步转动后,第二连通口212再与相邻的另一个第二开口12连通,继而进入第二导通模式,以此实现了介质流动路径的切换。而且,随着阀芯20的继续转动,先与第二连通口212连通的第二开口12的连通面积逐渐减小,后与第二连通口212连通的第二开口12的连通面积逐渐增大。
当多通阀100处于第三导通模式下,第一开口11依然作为进水口,第二开口12作为出水口,第一开口11与第一通道21通过第一连通口211始终处于导通,第二连通口212与一个第二开口12导通,第三连通口213与两个第二开口12中的另一个导通,也就是说两个第二开口12均有对应的连通口导通并与第一通道21实现连通。
当多通阀100处于第四导通模式下,第一开口11依然作为进水口,第二开口12作为出水口,第一开口11与第一通道21通过第一连通口211始终处于导通,区别在于,第三连通口213与一个第二开口12导通。也就是说,随着阀芯20的持续转动,处于第二导通模式下的第二连通口212转动到了与两个第二开口12均不连通的位置,此时第三连通口213转动到了在第一导通模式下的第二连通口212的位置,以与一个第二开口12连通,介质的流动路径为,从第一开口11进入,通过第一连通口211进入第一通道21,再从第三连通口213通过第二开口12流出。
当多通阀100处于第五导通模式下,第一开口11作为进水口,第二开口12作为出水口,第一开口11通过第一连通口211与第一通道21导通,第三连通口213与相邻的两个第二开口12导通。可以理解地,与第二导通模式类似,随着阀芯20的进一步转动,第三连通口213的位置从只与一个第二开口12连通的状态转动到与相邻的两个第二开口12均连通的状态,随着阀芯20的继续转动,先与第三连通口213连通的第二开口12的连通面积逐渐减小,后与第三连通口213连通的第二开口12的连通面积逐渐增大。
示例性地,请参见图8,黑色区域为能够供介质流动的区域,浅灰色区域为密封垫30,灰白色区域为密封垫30上开设得切口31,也就是能够与两个第二开口12连通的两个切口31。在图8中,阀芯20的转动角度为0°初始位置,多通阀100处于第一导通模式,第二连通口212仅与一个第二开口12连通。在阀芯20转动至25°时,请参见图9,阀芯20依然处于第一导通模式。
请参见图10,当阀芯20转动至48°时,多通阀100处于第二导通模式,第二连通口212与相邻的两个第二开口12连通,并且两个第二开口12与第二连通口212连通的面积相同。请参见图11,当阀芯20转动至70°时,第二连通口212与另一个第二开口12完全连通,一个的第二开口12保持关闭状态。
请参见图12,当阀芯20再进一步转动70°,两个第二开口12都保持关闭状态,此时进入第六导通模式,第二通道22与两个第二开口12连通。
当多通阀100处于第六导通模式下,至少一个第二开口12作为进水口,至少一个第二开口12作为出水口,第二通道22同时与进水口和出水口导通。也就是说,随着阀芯20的进一步转动,第二连通口212和第三连通口213都转动到不与第二开口12连通的位置,经第一开口11流入第二连通口212、第三连通口213的流体无法经第二开口12流出。此时,第一开口11既不作为进水口,也不作为出水口,而是两个第二开口12中的一个作为进水口,另一个作为出水口,介质从第二开口12中的一个流入到第二通道22中,通过第二通道22从另一个第二开口12流出,以此实现了管路的切换。
进一步地,第一通道21包括互相连通的第一腔214和第二腔215,第一腔214位于阀芯20靠近第一开口11的一端,第一腔214朝向第一开口11的一端的腔壁上开设有第一连通口211,第一连通口211始终与第一开口11连通,第二连通口212开设于形成第一腔214的腔壁上,随着阀芯20的转动,第一腔214通过第二连通口212和至少一个第二开口12连通。第二腔215位于阀芯20靠近第一开口11的一端,第二腔215朝向第一开口11的一端腔壁设有第五连通口216,第五连通口216始终与至少一个第一开口11连通,第三连通口213开设于形成第二腔215的周向腔壁上,随着阀芯20的转动,第二腔215通过第三连通口213和至少一个第二开口12连通。如此,第一通道21分为第一腔214和第二腔215,且第一腔214和第二腔215各自通过不同的连通口与第二开口12连通,便于实现更多的导通模式。在其他实施例中,第一腔214和第二腔215也可不连通。
需要解释的是,在本实施例中,第一腔214通过第二连通口212与第二开口12连通,随着阀芯的转动,第二腔215通过第三连通口213与第二开口12连通。第二连通口212和第三连通口213的位置相较于阀芯的中线对称,两者的结构以及技术效果相同,因此在其他实施例中,第二连通口212以及第三连通口213的位置也可以互相替换,而不限于上述第一腔214与第二连通口212相对应的实施方案。第一连通口211和第五连通口216均开设于阀芯20轴向的一侧端面上,第一腔214和第二腔215的横截面均设置为扇形,且第二连通口212和第三连通口213于阀芯20的周向的侧壁间隔设置。如此,扇形的第一腔214和第二腔215更加适配于圆形的阀芯20,且第二连通口212和第三连通口213开设于阀芯20的外周侧,随着阀芯20的转动,便于第二连通口212和第三连通口213与第二开口12连通。
当然,在其他实施例中,第二连通口212和第三连通口213也可以开设于阀芯20的轴向侧面上,增设其他流道与第二开口12连通,而不限于上述开设在阀芯20外周侧壁的方案。
阀芯20还包括与第一通道21间隔设置的第二通道22,阀芯20周向的侧壁上还开设有第四连通口221,第二通道22通过第四连通口221与至少两个第二开口12连通。如此,能够保证第六导通模式的实现,第四连通口221使得第二开口12中的介质能够进入第二通道22中,再从另一个第二开口12流出,以实现管路的切换,开设于侧壁上能够使得阀芯20通过简单的转动就让第四连通口221与第二开口12直接相对并连通。
进一步地,第二通道22内设有加强筋222,加强筋222分别连接于第二通道22在阀芯20的周向上的两侧内壁。如此,加强筋222能够提高阀芯20的结构强度,帮助阀芯20应力分摊,以提高阀芯20的耐用性。加强筋222的形式还能够减少其对于第二通道22内介质流动的影响。
请参见图7,阀芯20沿着周向分为第一扇形区23、第二扇形区24、第三扇形区25以及第四扇形区26,第二连通口212位于第一扇形区23,第三连通口213位于第三扇形区25,第四连通口221位于第四扇形区26;第二扇形区24位于第二连通口212与第三连通口213之间且间隔第二连通口212与第三连通口213。阀芯20设有第一分隔板27、第二分隔板28以及分割块29,分割块29位于第二扇形区24,且位于第二连通口212与第三连通口213之间,第一分隔板27位于第一扇形区23与第四扇形区26之间,第二分隔板28位于第三扇形区25与第四扇形区26之间。如此,第一分隔板27能够保证第一扇形区23和第四扇形区26之间的介质隔断,在只打开第一通道21或者第二通道22时能够避免介质混合。第二分隔板28能够保证第三扇形区25和第四扇形区26之间的介质隔断。分割块29使得第一扇形区23和第三扇形区25间隔设置,使得两者均能够独立连通于第二开口12。
相较于相关技术,本申请通过在阀芯20上开设第二连通口212、第三连通口213,通过阀芯20的转动使上述连通口选择性地与一个或两个第二开口12连通,以切换不同的导通模式,并且在不同导通模式下,第二开口12既能够作为进口也能够作为出口,结构简单稳定,并且变化灵活。随着阀芯20的转动,第二连通口212和第三连通口213都能分别与两个第二开口12连接,随着阀芯20转动,精确调整两个第二开口12的流量。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对申请专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干变形和改进,这些都属于本申请的保护范围。因此,本申请专利的保护范围应以所附权利要求为准。
