DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] 1 to 7, the present application provides a control valve 1000, which includes a valve body 1, a first valve core 2 and a second valve core 3. The valve body 1 is provided with a valve chamber 11, and the valve body 1 includes a body 14 and a valve cover 15, the body 14 is provided with an assembly port 141, and the valve cover 15 is fitted over the assembly port 141 and removably connected to the body 14. The valve chamber 11 is provided in the body 14, and the first valve core 2 and the second valve core 3 are installed in the valve chamber 11 of the body 14 through the assembly port 141. A side wall of the valve body 1 is provided with a plurality of communication holes 121, which pass through the side wall of the valve body 1 and communicate with the valve chamber 11. The first valve core 2 is rotatably mounted at one end of the valve chamber 11, the second valve core 3 is rotatably mounted at the other end of the valve chamber 11, and the second valve core 3 and the first valve core 2 are coaxially mounted.

[0011] 9, 14 and 20, the first valve core 2 is provided with a plurality of first passages 21 and a plurality of second passages 22 on its circumferential side, the second valve core 3 is provided with a third passage 31, and the communication hole 121 includes a plurality of first passages 121a and a plurality of second passages 121b. When the first valve core 2 is rotated by a first predetermined angle, the first passage 21 can communicate with two first passages 121a correspondingly, and the second passage 22 can communicate with one first passage 121a correspondingly. When the second valve core 3 is rotated by a second predetermined angle, the third passage 31 can communicate with one or two second passages 121b correspondingly, so that one first passage 121a communicates with one or two second passages 121b through the second passage 22 and the third passage 31 correspondingly, and the third passage 31 can communicate with the second passage 22 correspondingly.

[0012] Since the control valve 1000 includes two coaxially arranged first and second valve cores 2 and 3, the first and second valve cores 2 and 3 can be rotated by different angles to form a plurality of different communication modes in the control valve 1000. Specifically, assuming that the first valve core 2 can realize a type of communication mode by rotating by different angles, and the second valve core 3 can realize b type of communication mode by rotating by different angles, the entire control valve 1000 can realize a*b types of communication modes.

[0013] The communication modes include two-way or three-way flow paths formed at different positions of the control valve 1000. A two-way flow path refers to a fluid path that has only one inlet and only one outlet, and a three-way flow path refers to a fluid path that has only one inlet but two outlets, or two inlets but only one outlet.

[0014] The first passage 21 in the first valve core 2 can correspondingly connect the two first passages 121a in the communicating valve body 1 so that one or more two-way flow paths are formed in the control valve 1000, i.e., in this two-way flow path, a fluid enters the control valve 1000 from one of the first flow paths 121a and flows out of the control valve 1000 from the other first flow path 121a via the first passage 21.

[0015] Further, the second passage 22 can communicate with one first flow passage 121a, the third passage 31 can communicate with one or two second flow passages 121b, and the third passage 31 can communicate with the second passage 22. Therefore, one first flow passage 121a communicates with one or two second flow passages 121b via the second passage 22 and the third passage 31.

[0016] When one first flow path 121a correspondingly communicates with one second flow path 121b via the second passage 22 and the third passage 31, the control valve 1000 has a two-way flow path, i.e., fluid can enter the control valve 1000 from the first flow path 121a, then enter the second flow path 121b via the second passage 22 and the third passage 31, and finally leave the control valve 1000 via the second flow path 121b, or fluid can enter the control valve 1000 from the second flow path 121b, then enter the first flow path 121a via the third passage 31 and the second passage 22, and finally leave the control valve 1000 via the first flow path 121a.

[0017] When one first flow path 121a communicates with two second flow paths 121b correspondingly through the second passage 22 and the third passage 31, the control valve 1000 has a three-way flow path, that is, the fluid can enter the control valve 1000 from the first flow path 121a, then enter the two second flow paths 121b respectively through the second passage 22 and the third passage 31, and finally leave the control valve 1000 through the two second flow paths 121b; or the fluid can enter the control valve 1000 from the two second flow paths 121b, then enter the control valve 1000 from the third passage 31 and the second passage 32, and finally leave the control valve 1000 through the two second flow paths 121b. Fluid can enter the control valve 1000 through one of the first flow paths 121a via path 22 and finally leave the control valve 1000 through the first flow path 121a, or fluid can enter the control valve 1000 from one of the first flow paths 121a and one of the second flow paths 121b and finally leave the control valve 1000 through the other of the second flow paths 121b, or fluid can enter the control valve 1000 from one of the second flow paths 121b and finally leave the control valve 1000 through one of the first flow paths 121a and one of the second flow paths 121b.

[0018] As can be seen from the above, the control valve 1000 provided in the present application can achieve more communication modes than the conventional control valve 1000 with a single valve core structure. In addition, since the first valve core 2 and the second valve core 3 of the control valve 1000 are arranged in the same valve chamber 11 of the valve body 1, and the first valve core 2 and the second valve core 3 are arranged coaxially, the control valve 1000 of the present application has a more compact structure and a smaller volume than the conventional control valve 1000.

[0019] 5, the control valve 1000 has 2n first flow paths 121a, where n≧2, and the control valve 1000 has two second flow paths 121b. Each first passage 21 can form n-1 or less two-way flow paths by connecting two different first flow paths 121a, and one first flow path 121a can form one two-way flow path by connecting one second flow path 121b via the second passage 22 and the third passage 31. Alternatively, each first passage 21 can form n-1 or less two-way flow paths by connecting two different first flow paths 121a, and one first flow path 121a can form one three-way flow path by connecting two second flow paths 121b via the second passage 22 and the third passage 31. In this way, by making maximum use of the communication holes 121 provided in the valve body 1, the number of two-way flow paths that can be formed in the control valve 1000 can be increased, thereby increasing the usage rate of the control valve 1000.

[0020] 5, the communication holes 121 are distributed in two rows on the valve body 1, each row of the communication holes 121 includes n first flow paths 121a and one second flow path 121b, and the two second flow paths 121b are provided at the same end of the valve body 1. In this way, the distribution of the communication holes 121 in the valve body 1 is made more reasonable and aesthetically pleasing, which is advantageous for machining the communication holes 121 in the valve body 1, and improves the machining efficiency of the control valve 1000. However, the present invention is not limited to this, and the communication holes 121 may be distributed in different numbers of rows, such as three rows, four rows, five rows, etc., and they will not be listed here one by one.

[0021] In one embodiment, as shown in Figures 9 to 11 and 20, the first valve core 2 has a columnar structure, and the first valve core 2 is provided with a stop groove 23, which closes one first passage 121a. The first passage 21 includes an axial two-way groove 211 and a circumferential two-way groove 212, and the axial two-way groove 211 can connect two first passages 121a provided along the axial direction of the valve body 1, and the circumferential two-way groove 212 can connect two first passages 121a provided along the circumferential direction of the valve body 1. The first valve core 2 includes a first sector segment 24, a second sector segment 25, a third sector segment 26, a fourth sector segment 27 and a fifth sector segment 28, which have sector-shaped cross sections and are connected to each other in the circumferential direction of the first valve core 2.

[0022] Specifically, one end of the first sector segment 24 remote from the second valve core 3 is provided with two circumferential two-way grooves 212 distributed along the axial direction of the first valve core 2, and one end of the first sector segment 24 close to the second valve core 3 is provided with one axial two-way groove 211, one stop groove 23 and one second passage 22, where the axial two-way groove 211 is located on one side of the first sector segment 24 close to the second sector segment 25, the stop groove 23 and the second passage 22 are distributed along the axial direction of the first valve core 2 on one side of the first sector segment 24 close to the fifth sector segment 28, and the second passage 22 is close to the second valve core 3. The second sector segment 25 and the first sector segment 24 are mirror symmetrical. The third sector segment 26 is provided with one axial two-way groove 211, one stop groove 23, and one second passage 22, in that order, from a position away from the second valve core 3 to a position approaching the second valve core 3. The fourth sector segment 27 is provided with two axial two-way grooves 211, in that order, from a position away from the second valve core 3 to a position approaching the second valve core 3. The fifth sector segment 28 is provided with one axial two-way groove 211, one stop groove 23, and one second passage 22, in that order, from a position away from the second valve core 3 to a position approaching the second valve core 3.

[0023] More specifically, since n is 4, the control valve 1000 is provided with eight first flow paths 121a, and the eight first flow paths 121a and two second flow paths 121b are divided into two rows, and the two rows of communication holes 121 are mirror symmetrical. In this embodiment, the first valve core 2 and the second valve core 3 both rotate along the first direction E. The corresponding central angle of the cross section of the first sector segment 24 is 720° / 7, the corresponding central angle of the cross section of the second sector segment 25 is 720° / 7, the corresponding central angle of the cross section of the third sector segment 26 is 360° / 7, the corresponding central angle of the cross section of the fourth sector segment 27 is 360° / 7, and the corresponding central angle of the cross section of the fifth sector segment 28 is 360° / 7.
