[0030] As described in the background, the current complex flow path system is usually realized by configuring different numbers of three-way valves or / and four-way valves. For example, if the current system needs to realize a working mode of six interfaces, two four-way valves are usually needed to be set, as shown in Figure 1 The two four-way valves are a first four-way valve 1-0 and a second four-way valve 2-0, which are connected through pipelines. The specific connection mode can be referred to Figure 1 , Figure 1 The figure is a schematic diagram of forming a six-way valve by two four-way valves in the prior art, Figure 1 The first four-way valve 1-0 has four interfaces, which are a first valve interface 1-1, a second valve interface 1-2, a third valve interface 1-3, and a seventh valve interface 1-7. The second four-way valve 2-0 has four interfaces, which are a fourth valve interface 1-4, a fifth valve interface 1-5, a sixth valve interface 1-6, and an eighth valve interface 1-8. The seventh valve interface 1-7 of the first four-way valve 1-0 is in communication with the eighth valve interface 8 of the second four-way valve 2-0 through a pipeline. By controlling the valve core actions of the first four-way valve 1-0 and the second four-way valve 2-0 respectively, four modes can be selected. Figure 1 The double-headed arrow in the figure represents two interfaces in communication.
[0031] In mode 1, the first valve interface 1-1 and the second valve interface 1-2 are in communication, the third valve interface 1-3 and the seventh valve interface 1-7 are in communication, the sixth valve interface 1-6 and the eighth valve interface 1-8 are in communication, and the fourth valve interface 1-4 and the fifth valve interface 1-5 are in communication.
[0032] In mode 2, the first valve interface 1-1 and the second valve interface 1-2 are in communication, the third valve interface 1-3 and the seventh valve interface 1-7 are in communication, the fifth valve interface 1-5 and the sixth valve interface 1-6 are in communication, and the fourth valve interface 1-4 and the eighth valve interface 1-8 are in communication.
[0033] In Mode 3, the first valve interface 1-1 and the seventh valve interface 1-7 are communicated, the second valve interface 1-2 and the third valve interface 1-3 are communicated, the sixth valve interface 1-6 and the eighth valve interface 1-8 are communicated, and the fourth valve interface 1-4 and the fifth valve interface 1-5 are communicated.
[0034] In Mode 4, the first valve interface 1-1 and the seventh valve interface 1-7 are communicated, the second valve interface 1-2 and the third valve interface 1-3 are communicated, the fifth valve interface 1-5 and the sixth valve interface 1-6 are communicated, and the fourth valve interface 1-4 and the eighth valve interface 1-8 are communicated.
[0035] That is, by controlling the two-by-two communication of the other six interfaces of the two four-way valves, the control of the four modes is realized. Such a structure not only occupies a large space, but also the control logic is relatively complex.
[0036] Therefore, how to use a valve structure with a smaller volume to realize the control of four flow path modes in the case of six interfaces is the goal pursued by those skilled in the art.
