Description
Technical Field

With the development of automobiles, particularly new energy vehicle types, liquid circulation systems inside automobiles become more and more complex, a large number of pipelines, water valves, tee joints or cross joints and the like can be used in the systems, so that the space of the whole automobile is more and more compact, and certain parts in the front cabin of the automobile are difficult to arrange or even cannot be arranged.
Fig. 1 shows a conventional circulation system including two three-way valves a and b. When the circulating system works, the motor drives the internal shaft of the three-way valve a or b, so that the valve core arranged on the internal shaft of the three-way valve a or b is driven to move to block the corresponding pipe orifice flow channel, and the aim of controlling the flow direction of liquid is fulfilled.
The flow path mode of the circulating system mainly comprises a single circulation (series mode) and a double circulation (parallel mode), and the flow path mode comprises the following specific steps:
single cycle: at the moment, the K1 port of the three-way valve a is communicated with the K3 port, the K1 port is communicated with the K2 port, the K5 port of the three-way valve b is communicated with the K4 port, and the K5 port is communicated with the K6 port; the liquid circulation path is: the mouth C is greater than the mouth B, the engine is greater than the mouth A, the mouth D is greater than the air conditioner and the mouth C is greater than the mouth C.
Double circulation: at the moment, the K1 port of the three-way valve a is communicated with the K2 port, the K1 port is communicated with the K3 port, the K5 port of the three-way valve b is communicated with the K6 port, and the K5 port is communicated with the K4 port; the liquid circulation path is divided into two paths, one path is C port-D port-air conditioner port-C port, the other path is A port-B port-engine port-A port.

Meanwhile, as the circulating system has too many parts and complex assembly relation, the circulating system has more leakable points and larger leakage risk.
