[0026] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-6The utility model provides an embodiment: a three-way reversing valve, including a base 1, a liquid inlet 2 is fixedly connected to the front side of the base 1, a branch outlet 3 is fixedly connected to the rear side of the base 1, a partition 14 is arranged inside the branch outlet 3, and the branch outlet 3 is divided into two output chambers by the partition 14, two mounting sleeves 4 are connected inside the base 1, and the bottom ends of the two mounting sleeves 4 are connected by rotation, and the upper parts of the two mounting sleeves 4 are rotatably connected with a ball 2 6, and the bottom end of the ball 2 6 is fixedly connected with a ball 1 5, and the ball A flow path through hole 1 is provided inside the body 1 5, a flow path through hole 2 is provided inside the sphere 2 6, two flow path through holes 3 are provided on both the front and rear sides of the mounting sleeve 4, and two flow path through holes 4 are provided on both the front and rear sides of the base 1, the flow path through hole 1, the bottom flow path through hole 3 and the bottom flow path through hole 4 are connected, the flow path through hole 2, the top flow path through hole 3 and the top flow path through hole 4 are connected; the opening direction of the flow path through hole 1 is different from the opening direction of the flow path through hole 2, the top flow path through hole 4 is connected to the top output cavity, and the bottom flow path through hole 4 is connected to the bottom output cavity;

[0028] Specifically, the liquid inlet 2 serves as the inlet of the liquid, and the branch outlet 3 has two output ends, which are respectively connected to the corresponding output cavities and connected to different external liquid outlets. The directions of the flow path through hole 1 and the flow path through hole 2 are different. When the ball 1 5 and the ball 2 6 rotate 180°, the opening of one of the through holes of the flow path through hole 1 and the flow path through hole 2 will be connected to the flow path through hole 3 to transport the liquid. The other one will be restricted by the installation sleeve 4 after rotation, and the opening will be closed, so that different output cavities are selected for communication and the liquid outlet direction is changed. The modular design makes the maintenance and replacement of the valve easier. When repairs or replacement of parts are required, only the damaged module needs to be replaced instead of the entire valve system, thus saving time and cost.

[0029] The two separated sides of the two installation sleeves 4 are fixedly connected with plug-ins 7, and the installation sleeves 4 are plugged into the plug-in slots opened at the bottom of the base 1 through the plug-in 7. A locking member 10 is connected between two slide slots 1 8 opened on the upper left and right sides of the base 1 and a slide slot 2 9 opened at the top of the plug-in 7. One end of the locking member 10 is slidably connected to the inside of the slide slot 1 8, and the other end of the locking member 10 is interference-fitted inside the slide slot 2 9;

[0030] Specifically, the specification of the second slide groove 9 is slightly smaller than the locking member 10, so that after the locking member 10 slides into the second slide groove 9, the locking member 10 can be squeezed by the second slide groove 9 and thus fixed, so that the plug-in 7 and the base 1 are connected to each other, and the plug-in 7 and the installation sleeve 4 connected thereto are limited, and the installation sleeve 4 is stably installed inside the plug-in slot. By taking out and unfolding the installation sleeve 4, the surfaces of the mutually connected spheres 1 5 and 2 6 can be cleaned, and the inside of the plug-in slot can be cleaned and maintained simply and conveniently, thereby ensuring the normal operation of the reversing valve, and further preventing the accumulation of dirt and impurities inside the reversing valve, which would affect the work of conveying liquid.

[0031] The rotating handle 13 is rotatably connected to the top of the base 1, and is fixedly connected to the spline groove 11 at the top of the sphere 2 6. The top of the spline groove 11 passes through the top sides of the two mounting sleeves 4. The bottom end of the rotating handle 13 is fixedly connected to the spline shaft 12, and the spline shaft 12 is inserted into the inner wall of the spline groove 11.

[0032] Specifically, the tooth groove density inside the spline groove 11 is greater than the tooth groove density of the outer wall of the spline shaft 12, so that the spline shaft 12 can be inserted into the spline groove 11 from any angle. By rotating the rotating handle 13 connected to the spline shaft 12 externally, the spline shaft 12 drives the ball 1 5 connected to the spline groove 11 and the ball 2 6 to rotate.

[0033] Working principle: When changing the flow direction of the liquid, the rotating handle 13 connected to the spline shaft 12 is rotated externally, so that the spline shaft 12 drives the ball 1 5 connected to the spline groove 11 together with the ball 2 6 to rotate, so that the ball 1 5 and the ball 2 6 rotate 180°. At this time, the opening of one of the through holes of the flow path through hole 1 and the flow path through hole 2 is connected to the flow path through hole 3 to transport the liquid, and the other one is restricted by the installation sleeve 4 after rotation, and the opening is closed, so that different output cavities are selected for connection to change the liquid discharge direction. When it is necessary to clean and maintain the inside of the reversing valve, the locking piece 10 is slid to disengage the locking piece 10 from the slide groove 2 9, thereby releasing the connection between the base 1 and the plug-in 7, and then the mounting sleeve 4 is pulled out, so that the connected ball 1 5 and ball 2 6 located in the mounting sleeve 4 are taken out together. At this time, the spline groove 11 connected to the ball 2 6 is disengaged from the spline shaft 12, and then the mounting sleeve 4 is unfolded, and the surfaces of the interconnected ball 1 5 and ball 2 6 are cleaned, as well as the inside of the plug-in slot for simple and convenient cleaning and maintenance.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
