Etc. several parts composition；The mobile phase of liquid chromatograph liquid chromatograph squeezes into system, sample solution warp by high-pressure pump in reservoir
Injector enters mobile phase, and chromatographic column is loaded into by mobile phase（Stationary phase）It is interior, because each component in sample solution is in two-phase
With different distribution coefficients, when being performed relative motion in two-phase, by the assigning process of repeated multiple times absorption-desorption, respectively
Component produces larger difference in translational speed, is separated into single component and is flowed out successively out of post, during by detector, sample
Product concentration is converted into electric signal and is sent to recorder, data with collection of illustrative plates form print high performance liquid chromatograph mainly have into
Sample system, transfusion system, piece-rate system, detecting system and data handling system, existing separate unit liquid phase complete inspection only for detection
, it is necessary to disassembly, cleaning after survey；It is wasted time and energy, and need to such as realize while cleaning chromatographic column function, high cost need to be put into again and is purchased
The Liquid apparatus of cleaning.
Utility model content
To solve the above problems, the utility model proposes a kind of on-line cleaning pump of liquid chromatograph, using triple valve
Coordinate with the pump housing, realize online wash cycles, without dismounting, you can complete the cleaning of chromatographic column.

The first triple valve on front side of valve, and the second triple valve being serially connected between chromatographic column and detector；The pump housing two ends connect respectively
It is connected to the 3rd end of the first triple valve and the second triple valve；Charging valve is provided between the pump housing and the first triple valve；It is described
Tapping valve is provided between second triple valve and the pump housing.
As preferred embodiment, the charging valve is connected to cleaning fluid proportioning storehouse；The cleaning fluid proportioning storehouse passes through
Proportioning valve is connected to single product fluid reservoir.
Further, the proportioning valve is quaternary proportioning valve.
As preferred embodiment, the tapping valve output end is provided with the 3rd triple valve；The 3rd triple valve bottom
