The invention relates to diluents and liquid dispensers of multicomponent systems and can be used to prepare samples of aqueous solutions with predetermined concentrations of various substances in instrument-making, chemical, petroleum and any other industry where it is required to obtain aqueous solutions of different concentrations,

The purpose of the invention is to improve the accuracy of dosing of liquids,

The drawing shows the proposed device, the overall appearance.

The automatic fluid diluent contains auxiliary vessel 1 of a constant level of the dilutable liquid and auxiliary vessel of a constant level 2 diluted

common fluid. The vessel 1 is rigidly connected to the working vessel 3 at a constant level of the dilutable liquid. The vessel 3 contains a piston 4 equipped with a scale 5 with graduated divisions, a pointer 6 level. The vessel 3 is connected to the siphon 7, the vessel 2 of a constant level of the diluent liquid is rigidly connected to the working vessel B of a constant level of the diluent liquid, and the vessel B to a siphon 9 connected to the jet pump 10 brought into the mixing vessel 11 This siphon 7 is also connected to the jet

10, the vessel is rigidly connected to the working vessel 3 via pipe 12, and the vessel 2 is connected to the working vessel 8 through pipe 13, vessels 1 and 2 are filled through pipes 14 and 15, constant liquid level in vessels 1,2 , 3 and 11 are supported by drain pipes 16-19, respectively.

Automatic diluent, the fluid works as follows.

Diluted, for example, the waste liquid is supplied to vessel 1 through conduit 14, the stock of excess liquid is maintained through a conduit 16 to maintain a constant level. Then the liquid enters working vessel 3 of the dilutable liquid through conduit 12. The volume of fluid in vessel 3 is adjusted by moving the piston 4 with a scale of 5 and a level indicator 6, while the dimensional divisions can be scaled in a volume ratio of mixed fluids, since vessel 8 has a constant volume. The excess liquid from the vessel. 3 is drained through the pipe 18. At the same time, the diluent, for example, the clean liquid through the pipe 15 enters the vessel 2 at a constant level. The drain of excess liquid to maintain a constant level is carried out through the drain pipe 17, Vessels 1 and 2 are used to pre-accumulate volumes of liquids. Then the dilution fluid through conduit 13 enters the working vessel 8. In this design, vessels 3 and 8 are such that the working vessel 3 is filled earlier than the working vessel 8 and is in standby mode. Then the filling of the working vessel 8 with the dilution liquid is completed and a siphon is triggered.

9 which starts the jet pump

10, and the liquid from the vessel 8 through the siphon 9 enters the mixing vessel 11 and empties the vessel B. At the same time, the jet pump 10 through the siphon 7 pumps out the diluted liquid from the vessel 3 to the mixing vessel 11, the excess liquid from which is drained through pipe 19, After discharge of liquids from vessels 3 and 8 jet pump 10 stops CBOJO work, there is a new filling of working vessels 3 and 8, after which the cycle of discharge

and the mixing of liquids is repeated.

Thus, during one dilution cycle, liquids are automatically dispensed. The volumes of diluted and dilution liquids remain constant during one cycle, resulting in

high dosing accuracy is achieved. By preliminarily changing the volume of the diluted liquid with the help of a piston, it is possible to achieve the required ratio of the volumes of the liquids to be drained, with this, the accuracy of dosing is improved,
