[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0035] like Figures 1 to 9 As shown, an embodiment of the utility model provides a multi-way valve, including a valve body 10, a valve core member 21, a valve core shaft 22, a limit assembly 30 and an elastic member 40. The valve core shaft 22 is located in the valve body 10 and one end is fixedly arranged at the bottom of the cavity of the valve body 10. The valve core member 21 is sleeved on the outer periphery of the valve core shaft 22 and is rotatably arranged in the valve body 10 to switch the flow condition of the multi-way valve. The limit assembly 30 is arranged on the valve core shaft 22 and is located on the side of the valve core member 21 away from the bottom of the cavity of the valve body 10. The two ends of the elastic member 40 are respectively abutted against the limit assembly 30 and the valve core member 21 to press the valve core member 21 against the bottom of the cavity of the valve body 10.

[0036] In this embodiment, one end of the valve core shaft 22 is fixed to the bottom of the cavity of the valve body 10 and the limit assembly 30 is arranged on the valve core shaft 22, which is conducive to limiting the relative positions of the valve core shaft 22, the limit assembly 30 and the valve body 10, and further ensuring the compression effect of the elastic member 40 on the valve core member 21. On the other hand, compared with the situation in the prior art that the two ends of the elastic member 40 are respectively in contact with the driving shaft 51 of the execution drive assembly 50 and the valve core member 21, this scheme is conducive to reducing the height of the area for placing the elastic member 40, thereby increasing the compression degree of the elastic member 40 and the downward pressure effect on the valve core member 21, avoiding the situation in the prior art that the elastic member 40 is prone to insufficient pressure on the valve core member 21, resulting in the valve core member 21 being easy to move, and then causing the multi-way valve to leak. In addition, the elastic force at both ends of the elastic member 40 can be transmitted to the valve body 10, and the valve cover 12 is not subjected to force. The strength of the valve body 10 is greater than that of the valve cover 12, and even if the valve body 10 is subjected to the elastic force of the elastic member 40, it is not easy to deform. The valve cover 12 is not subjected to force, so that deformation of the valve cover 12 due to the elastic force of the elastic member 40 can be avoided, thereby improving and ensuring the stability of the valve core member and the accuracy and reliability of the multi-way valve in controlling the fluid.

[0037] like Figure 2 and Figure 3 As shown, the limit assembly 30 includes a clamping spring 31 and a gasket 32 ​​sleeved on the valve core shaft 22, the two ends of the elastic member 40 respectively abut against the gasket 32 ​​and the top surface of the valve core member 21, the clamping spring 31 is clamped on the valve core shaft 22, and the gasket 32 ​​cooperates with the clamping spring 31 as a stop. In this way, the end of the elastic member 40 abuts against the gasket 32, which is conducive to increasing the abutment effect between the elastic member 40 and the limit assembly 30. On the other hand, the clamping spring 31 can realize the stop restriction of the gasket 32 ​​along the axial direction of the valve core shaft 22, so as to ensure the reliability of the height of the area for placing the elastic member 40 to improve the compression degree of the elastic member 40.

[0038] like Figure 3 As shown, the outer periphery of the valve core shaft 22 is provided with an annular clamping groove 221, and the clamping spring 31 is clamped in the annular clamping groove 221 to limit the position of the clamping spring 31 on the valve core shaft 22. This arrangement further ensures the limitation of the relative position of the clamping spring 31, the valve core shaft 22, and the valve body 10, and the compression effect of the elastic member 40 on the valve core member 21. There is a certain assembly gap between the annular clamping groove 221 and the clamping spring 31 to ensure the reliability of the installation of the clamping spring 31.

[0039] like Figure 4 As shown, the clamping spring 31 is a strip-shaped circular ring with an opening, and the two ends of the clamping spring 31 can move closer to or farther from each other to drive the clamping spring 31 to elastically deform and clamp or loosen the annular clamping groove 221. It can be understood that the clamping spring 31 in this embodiment includes a clamping ring 311 and a clamping groove 312. The clamping ring 311 is a strip-shaped circular ring with an opening. The area surrounded by the clamping ring 311 forms a clamping area for clamping the annular clamping groove 221. Two clamping grooves 312 are symmetrically arranged at both ends of the clamping ring 311. The two clamping grooves 312 can move closer to or farther from each other to drive the clamping ring 311 to elastically deform and open and close the clamping area. In this way, the operator can control the elastic opening and closing of the clamping ring 311 by adjusting the two clamping grooves 312, which is convenient for operation.

[0040] like Figure 2 and Figure 6As shown, the valve core member 21 has a first limiting groove 211 on the side away from the bottom of the cavity of the valve body 10, at least part of the valve core shaft 22 is located in the first limiting groove 211, the gasket 32 ​​and the elastic member 40 are both located in the first limiting groove 211, the two ends of the elastic member 40 are respectively in contact with the gasket 32 ​​and the bottom wall of the first limiting groove 211, and a stop step is provided in the first limiting groove 211, and the side of the gasket 32 ​​away from the retaining spring 31 is engaged with the stop step. In this way, the first limiting groove 211 is used to guide and limit the installation of the limiting assembly 30, which is conducive to ensuring the coaxiality of the valve core shaft 22, the valve body 10, the limiting assembly 30, and the valve core member 21, and the stop step stops the gasket 32, so as to achieve the stop limit of the gasket 32 ​​along the axial downward direction of the valve core shaft 22, so as to ensure the reliability of the area height for placing the elastic member 40 to improve the compression degree of the elastic member 40.

[0041] Specifically, the first limiting groove 211 includes a first groove section 2111 and a second groove section 2112 which are connected to each other. The radial dimension of the first groove section 2111 is larger than that of the second groove section 2112. The first groove section 2111 is located on the side of the valve core member 21 away from the bottom of the cavity of the valve body 10. The gasket 32 ​​is movably arranged in the first groove section 2111. A part of the elastic member 40 is telescopically arranged in the second groove section 2112. The connection position of the first groove section 2111 and the second groove section 2112 forms a stop step. The gasket 32 ​​and the inner wall limiter of the first groove section 2111 cooperate with each other and cooperate with the bottom wall stop of the first groove section 2111.

[0042] In this embodiment, the radial dimension of the gasket 32 ​​is greater than the radial dimension of the elastic member 40, and the gasket 32 ​​is limitedly matched with the inner wall of the first slot section 2111, and the movement of the gasket 32 ​​is guided by the first slot section 2111 to avoid deviation or deflection of the gasket 32 ​​during movement, and the elastic member 40 and the inner wall of the second slot section 2112 are limitedly matched to facilitate the installation of the elastic member 40. Such a configuration is conducive to ensuring the installation and guiding effect of the elastic member 40 and the limiting assembly 30, and is also conducive to the forming of the stop step.

[0043] Preferably, the valve core shaft 22 in this embodiment is injection molded and embedded in the bottom of the cavity of the valve body 10. This arrangement facilitates the fixed connection between the valve core shaft 22 and the valve body 10, and is also conducive to reducing assembly time, reducing costs, and increasing overall structural strength.

[0044] like Figure 1 , Figure 2 and Figure 5As shown, the multi-way valve further includes an actuator drive assembly 50 having a drive shaft 51, which is disposed at the top of the valve body 10, one end of the drive shaft 51 penetrates into the cavity of the valve body 10, and one end of the drive shaft 51 penetrates into the cavity of the valve body 10 and is limitedly matched with the valve core member 21 and is drivingly connected to the valve core member 21. This arrangement is conducive to ensuring the reliability and stability of the drive shaft 51 driving the valve core member 21.

This arrangement facilitates the driving shaft 51 to drive the valve core member 21.

[0046] Specifically, the mating portion is a snap-fitting protrusion 512 , and the mated portion includes a first limiting groove 211 and a plurality of limiting snap-fitting grooves 212 circumferentially spaced around the opening edge of the first limiting groove 211 , and the plurality of snap-fitting protrusions 512 are disposed in the plurality of limiting snap-fitting grooves 212 in a one-to-one correspondence.

[0047] In this way, the driving shaft 51 is clamped with the valve core 21 to ensure that the driving shaft 51 drives the valve core 21 to rotate. A plurality of limiting grooves 212 are arranged at intervals along the circumferential edge of the opening of the first groove section 2111 of the first limiting groove 211, and the depth of the limiting grooves 212 is less than the depth of the first groove section 2111.

[0048] like Figure 2As shown, the multi-way valve also includes a valve core sealing gasket 61 disposed between the valve core member 21 and the bottom of the cavity of the valve body 10, and the elastic member 40 is used to press the valve core member 21 onto the valve core sealing gasket 61 and press the valve core sealing gasket 61 onto the bottom of the cavity of the valve body 10. In this embodiment, the bottom of the valve body 10 has a plurality of flow holes 101 distributed along its circumference, and the valve core member 21 also has a plurality of flow channels spaced from each other, and the openings at both ends of the flow channels correspond to the flow holes 101 at different positions, respectively. The valve core sealing gasket 61 is disposed around the plurality of flow holes 101, and the plurality of flow channels include a first flow channel 213 and a second flow channel 214. The valve core sealing gasket 61 is used to seal the edges of the plurality of flow holes 101 and the opening edges of the flow channels, so as to prevent the fluid from leaking easily from the connecting position between the flow hole 101 and the opening of the flow channel. Specifically, an annular sealing groove for installing a valve core sealing gasket 61 is provided on the bottom of the cavity of the valve body 10. The thickness of the valve core sealing gasket 61 is greater than the groove depth of the annular sealing groove and protrudes out of the annular sealing groove. The valve core member 21 is pressed down on the valve core sealing gasket 61 located in the cavity of the valve body 10 under the action of the limit assembly 30 and the elastic member 40 to ensure the sealing effect and reliability of the valve core sealing gasket 61 between the valve body 10 and the valve core member 21.

[0049] Optionally, the valve body 10 is composed of a valve seat 11 and a valve cover 12, the valve seat 11 and the valve cover 12 together surround a cavity of the valve body 10, and a plurality of flow holes 101 are arranged at the bottom of the valve seat 11.
