[0028] Further, the driving mechanism includes a valve rod 320 extending in the up-down direction, the upper surface of the valve shell 310 is provided with an opening 315, the valve rod 320 is fixedly connected with the upper end of the valve core 340 through the opening 315, and the valve rod 320 can rotate around its own axis, so as to realize the rotation of the valve core 340 around the first axis.

[0029] Further, the outer surface of the valve core 340 is provided with two parallel arranged ring grooves 341, the axis of each ring groove 341 is parallel to the second axis, a gear ring 342 is coaxially arranged in the ring groove 341, the driving mechanism further includes two rotating rods 330 extending in the up-down direction, the lower end of each rotating rod 330 is provided with a gear 331, both rotating rods 330 are inserted into the corresponding ring groove 341 through the opening 315, and the gear 331 is engaged with the corresponding gear ring 342, and the two rotating rods 330 can synchronously rotate around their own axes, so as to realize the rotation of the valve core 340 around the second axis.

[0030] Further, the opening 315 is coaxially provided with a valve sleeve 321, the valve rod 320 is located in the inside of the valve sleeve 321, and the rotating rod 330 is arranged on the valve sleeve 321, and both the rotating rod 330 and the valve rod 320 can rotate relative to the valve sleeve 321.

[0031] Further, the driving mechanism further includes an operation box 200, the operation box 200 is located above the valve shell 310, a rotating handle 201 is rotatably arranged in the operation box 200, the rotating handle 201 is in transmission connection with the valve rod 320, and the rotating handle 201 can rotate around the second axis, so as to drive the valve rod 320 to rotate around the first axis. Specifically, the rotating handle 201 and the valve rod 320 can be in transmission cooperation through a bevel gear.

[0032] Furthermore, the drive mechanism also includes an electric controller 100, which is located above the control box 200. The electric controller 100 can drive the valve stem 320 to rotate around the first axis and the two rotating rods 330 to rotate synchronously around their own axes.

[0033] Based on the above embodiments, the usage principle and working process of the embodiments of the present invention are as follows: like Figure 11 As shown, valve 300 is in the first state (i.e., the initial state). At this time, the second valve port 312 on valve body 310 is connected to the first valve port 311 through the first docking channel, and the third valve port 314 is connected to the fourth valve port 316 through the second docking channel, realizing the first four-way mode.

[0034] When it is necessary to change the connection method of the four-way valve, rotate the valve stem 320 by turning the handle 201, so that the valve stem 320 rotates clockwise around the first axis (i.e., the upper and lower axes). Figure 11 (Viewed from top to bottom) Rotate 90°. At this point, the third valve port 314 on the valve housing 310 is connected to the first valve port 311 through the first docking channel, and the fourth valve port 316 is connected to the second valve port 312 through the second and third docking channels, thus realizing the second four-way mode. Alternatively, continue to rotate the valve stem 320 by rotating the handle 201, so that the valve stem 320 continues to rotate clockwise to 180°, so that the fourth valve port 316 on the valve housing 310 is connected to the first valve port 311 through the first docking channel, and the third valve port 314 is connected to the second valve port 312 through the third docking channel, thus realizing the third four-way mode.

[0035] When it is necessary to switch to two-way mode, valve 300 should be reset to its original position. Figure 11 The first state is shown. Subsequently, the electric controller 100 controls the two rotating rods 330 to rotate synchronously and in the same direction, causing the valve core 340 to rotate clockwise around the second axis (i.e., the horizontal axis). Figure 11 (Viewed from top to bottom) Rotate 90° to make valve 300... Figure 12 The second state is as follows. At this time, the third valve port 314 is connected to the first valve port 311 through the third docking channel, while the second valve port 312 and the fourth valve port 316 are closed, achieving the first two-way mode. Then, the electric controller 100 controls the two rotating rods 330 to rotate synchronously and in the same direction, causing the valve core 340 to rotate clockwise around the second axis (i.e., the horizontal axis). Figure 12 (Viewed from top to bottom) Rotate 90° to make valve 300... Figure 13the third state shown in FIG. 3B. At this time, the second valve port 312 and the third valve port 314 are communicated through the third interface channel, the first valve port 311 and the fourth valve port 316 are closed, and the second two-way mode is realized. Then, the handle 201 is rotated to drive the valve rod 320 to rotate the valve core 340 by 180°, so that the third valve port 314 and the fourth valve port 316 are communicated through the second interface channel, the first valve port 311 and the second valve port 312 are closed, and the third two-way mode is realized. Subsequently, the handle 201 is rotated to drive the valve rod 320 to continuously rotate the valve core 340 by 270°, so that the second valve port 312 and the fourth valve port 316 are communicated through the second interface channel and the third interface channel, the first valve port 311 and the third valve port 314 are closed, and the fourth two-way mode is realized.

[0036] Then, the valve 300 can be reset to the third state shown in FIG. 3B by the electric controller 100, and the two rotating rods 330 are controlled to rotate synchronously and in the same direction by the electric controller 100, so that the valve core 340 is rotated clockwise (from top to bottom in FIG. 3B) by 90° around the second axis (i.e., the horizontal axis), and the valve 300 is in the fourth state shown in FIG. 3C. Figure 13 Figure 13 Then, the handle 201 is rotated to drive the valve rod 320 to rotate clockwise (from top to bottom in FIG. 3B) by 180°, so that the second valve port 312 and the first valve port 311 are communicated through the first interface channel, and the third valve port 314 and the fourth valve port 316 are closed, and the fifth two-way mode is realized. Figure 14 Figure 13 Then, the handle 201 is rotated to drive the valve rod 320 to rotate clockwise (from top to bottom in FIG. 3B) by 180°, so that the second valve port 312 and the first valve port 311 are communicated through the first interface channel, and the third valve port 314 and the fourth valve port 316 are closed, and the fifth two-way mode is realized.

[0037] In summary, the valve 300 can realize three four-way modes and six two-way modes, so as to realize the communication of any two valve ports and the closing of the remaining two valve ports, and the two-by-two communication of the four valve ports, and is flexible to use and good in versatility.

[0039] ​​Any combination of the technical features in the above embodiments can be made, and for the sake of brevity, not all possible combinations are described above. However, any combination of the technical features is deemed to be within the scope of the present disclosure as long as such a combination does not result in an inconsistency.

[0040] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but should not be understood as a limitation on the scope of the present application. It should be noted that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
