The embodiment of the utility model provides an adopt progressive mode to write.
In an embodiment of a three-way valve with exhaust, as shown in fig. 1, a three-way valve body 1 with exhaust comprises a valve body 11, wherein the valve body 11 is provided with an inlet, a main outlet and a branch outlet; an exhaust nut 12 installed at an inlet end of the valve body 11 and having an exhaust hole 13 at a top thereof; a ball valve 14 is mounted at the main outlet end of the valve body 11. The valve body 11 of the three-way valve body 1 with exhaust has an inlet, a main outlet and a branch outlet, an exhaust nut 12 is arranged at the inlet end of the valve body 11, an exhaust hole 13 is arranged at the top of the exhaust nut 12, and a ball valve 14 is arranged at the main outlet end of the valve body 11. An inlet, a main outlet and a branch outlet of a valve body 11 of the three-way valve are respectively connected with a cooling water path and an expansion kettle water path of a cooling system. When cooling liquid circulates in a cooling water path or gas with certain pressure is left in the filling process, the ball valve 14 of the three-way valve is closed, only the water path of the expansion pot is unblocked, the cooling liquid is filled from the expansion pot 2, at the moment, the exhaust nut 12 is opened, and the gas is discharged through the exhaust hole 13 at the top of the exhaust nut 12 to finish the exhaust; when no gas is discharged from the pipeline, the exhaust nut 12 is locked, the ball valve 14 is opened, and the cooling water path is recovered. When the ball valve 14 is opened, the cooling water path is communicated with the two water paths of the expansion kettle; when the ball valve 14 is closed, the water path of the expansion pot is communicated, and the air exhaust work can be carried out.
Preferably, on the basis of the above embodiment, the ball valve 14 and the vent nut 12 are controlled by an automatic control system. The three-way valve with exhaust corresponds to a liquid flow direction switching valve. When the gas in the cooling system is detected to exceed the standard, the automatic control system is intelligently switched to the expansion pot water path to control the ball valve 14 to be intelligently closed, meanwhile, the automatic control system controls the exhaust nut 12 to be intelligently opened, the cooling liquid is filled from the expansion pot 2, and at the moment, the gas is exhausted through the exhaust hole 13 in the top of the exhaust nut 12; when no gas is discharged from the cooling system pipeline, intelligently closing the exhaust nut 12 and opening the ball valve 14; namely, the cooling system controls the action of related components through an automatic control system, and performs automatic exhaust and cooling water path recovery.
An embodiment of a cooling system, as shown in fig. 2, comprises a cooling water path and an expansion pot water path, wherein a battery pack cooling water pipe 3, a cooling fan 4 and a water pump 5 are arranged on the cooling water path; an expansion pot 2 is arranged on the water way of the expansion pot; the expansion pot water path is connected with the water pump 5 in parallel; an inlet, a main outlet and a branch outlet of the valve body 11 of the three-way valve with the exhaust function are respectively connected with the cooling water path and the expansion kettle water path.
