[0026] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0027] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component can be changed at will, and the component layout may also be more complex.

[0028] The following is combined with Figure 1-5 The specific implementation methods of the present invention are further described.

[0029] Example:

[0030] The present invention discloses a universal temperature control valve. Figure 1 As shown, the installation diagram of 90 degree posture. Figure 2 This is an installation diagram for a 270-degree posture. Figure 3 It is a schematic diagram of installation in a 180-degree posture, and illustrates that the first type universal tube 41, the second type universal tube 42, the third type universal tube 43, and the fourth type universal tube 44 can be freely rotated and combined.

[0031] Specifically, in this solution, combined with Figure 4 and Figure 5 As shown, it includes an inner valve body 1, with a first valve core assembly 2 mounted on one end of the inner valve body 1 and a second valve core assembly mounted on the other end of the inner valve body 1. A first type through hole 11, a second type through hole 12, a third type through hole 13, and a fourth type through hole 14 are provided in the middle portion of the inner valve body 1. Four through holes 11 of each type are provided and are evenly distributed circumferentially on the side wall of the inner valve body 1. A first type universal tube 41 is sleeved and rotatably connected to the first type through hole 11 of the inner valve body 1, a second type universal tube 42 is sleeved and rotatably connected to the second type through hole 12, a third type universal tube 43 is sleeved and rotatably connected to the third type through hole 13, and a fourth type universal tube 44 is sleeved and rotatably connected to the fourth type through hole 14.

[0032] In order to make the structure more compact, save space and reduce the volume, the water inlets of the first and second universal tubes 41 and 42 have a staggered combination structure 5 , and the water inlets of the third and fourth universal tubes 43 and 44 also have a staggered combination structure 5 .

[0033] The specific staggered assembly mechanism is as follows: the staggered assembly structure 5 includes two complementary first and second assembly parts 51, 52, each of which includes a universal ring 61, a limit ring 62, and a tube 63. The universal ring 61 of the first assembly part 51 is located on the limit ring 62 of the second assembly part 52, and the universal ring 61 of the second assembly part 52 is located on the limit ring 62 of the first assembly part 51, so that the axis centers of the tubes 63 of the first and second assembly parts 51, 52 are in the same rotation plane. This structure not only reduces the overall volume, but also, by utilizing the limit position after assembly, makes the circumferential rotation between them more stable and reliable.

[0034] In order to avoid interference in the side-by-side rotation, a spacer tube 7 is provided between the second universal tube 42 and the third universal tube 43. The spacer tube 7 is sleeved between the second through hole 12 and the third through hole 13 of the inner valve body 1. This allows the left and right universal tubes to have a reasonable spacing and is also easy to install.

[0035] Of course, sealing rings 8 are respectively provided at both ends of the universal ring 61, and the sealing rings 8 are also fitted on the outer wall of the inner valve body 1. In this way, reliable sealing can be achieved, and liquid (water) will not leak during the rotation operation.

[0036] Further, in Figure 5 In the figure, the first valve core assembly 2 includes a seat body 21, a valve core 22, a valve stem 23, a spring 24, and a retaining spring 25. The seat body 21 is threadedly fixed on the end of the inner valve body 1, the valve stem 23 is passed through the seat body 21, the retaining ring is fixed on the valve stem 23 and is in the inner cavity of the seat body 21, the spring 24 is sleeved on the valve stem 23, one end of the spring 24 is in contact with the retaining spring 25, and the other end of the spring 24 is in contact with the inner cavity of the seat body 21, the valve core 22 is fixed on the end of the valve stem 23 and is on the outside of the seat body 21 and is kept in a retracted state by the action of the spring 24. The valve core 22 is used to close the channels of the first through hole 11 and the second through hole 12 inside the inner valve body 1.

[0037] The function of the first valve core assembly 2 is described as follows: the force of the spring 24 keeps the valve stem 23 moving backward (to the right in the figure), so that the retaining spring 25 rests against the rear seat position of the seat body 21. The seat body 21 is composed of a front seat and a rear seat, which are assembled through a threaded structure to form an inner cavity structure for the installation of the spring 24. By pushing the valve stem 23, the spring 24 can be compressed, so that the valve stem 23 is in an extended state. At this time, when the valve stem 23 pushes the valve core 22 to the hollow channel opening of the inner valve body 1, this channel is cut off and water cannot pass. Therefore, at this time, a type of universal tube 41 is cut off (closed) and water cannot flow out. That is, water cannot flow out in the D2 direction. On the contrary, after being released, the valve stem 23 is reset under the action of the spring 24, and water flow in the D2 direction is restored.

[0038] It should be noted that the first type universal tube 41 is for water outlet, the second type universal tube 42 is for water inlet, the third type universal tube 43 is for water outlet, and the fourth type universal tube 44 is for water inlet. The arrow directions shown by D1, D2, D3 and D4 are the directions of water flow.

[0039] On the other hand, for more reliable control, the second valve core assembly includes a first-level adjusting seat 31, a second-level adjusting seat 32, and a tail seat 33. The tail seat 33 is installed at the end of the inner valve body 1, the first-level adjusting seat 31 is installed at the inner end of the tail seat 33, and the second-level adjusting seat 32 is threadedly assembled inside the first-level adjusting seat 31. A sealing tube 34 is provided in the channel of the inner valve body 1 between the second-class through hole 12 and the third-class through hole 13. The second-class adjusting seat 32 is used to open and close the sealing tube 34, and the first-class adjusting seat 31 is used to open and close the connection between the fourth-class through hole and the third-class through hole 13.

[0040] As can be seen, the secondary adjustment seat 32 can either close or open the sealing tube 34. When the sealing tube 34 is opened, the secondary adjustment seat 32 and the primary adjustment seat 31 can move to the left together, allowing the third and fourth universal tubes 43, 44, and the internal channel of the inner valve body 1 to communicate with each other, thus allowing water to flow. Otherwise, the third and fourth universal tubes 43, 44 can be disconnected, thus cutting off the water flow.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, any equivalent variations based on the structure, shape, or principles of the present invention are intended to be within the scope of protection of the present invention.
