The present invention can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed by the present invention.

[0027] Explanation of reference numerals: Since the reagent inlet 11, the cleaning medium inlet 12, the passage 13 and the plurality of outlets 14 in the drawings are all equipped with connectors, the reference numerals of the above components actually refer to the corresponding ports rather than the connectors herein.

[0028] Embodiment: A highly integrated liquid pumping valve device, such as Figures 1 to 5 As shown, it includes a valve bracket 1, a switching valve 2 and a plurality of solenoid valves 3, the valve bracket is provided with a reagent inlet 11, a cleaning medium inlet 12, a passage 13 and a plurality of outlets 14, the switching valve is fixedly mounted at one end of the valve bracket, and the reagent inlet and the cleaning medium inlet are respectively connected to the corresponding positions of the switching valve;

[0029] The solenoid valves are arranged in sequence on the upper surface of the valve bracket, the passage is connected to the switching valve and all the solenoid valves at the same time, and the solenoid valves are also connected to the corresponding outlets;

[0030] The valve bracket is provided with a one-way valve (not shown in the figure) at the corresponding reagent inlet and cleaning medium inlet;

[0031] The reagent is injected into the switching valve through the reagent inlet; the cleaning medium is injected into the switching valve through the cleaning medium inlet.

The three-way valve is controlled by electromagnetic to open or close the valve, thereby controlling the flow or stop of the medium through the pipeline. Normally open and normally closed refer to the state of the valve when there is no power, also known as the initial state or dormant state. When there is no power on, the normally open valve is in a closed state, and the valve opens after power is turned on; when there is no power on, the normally closed valve is in an open state, and the valve closes after power is turned on.
