Abstract

The invention relates to a measurement technique and allows the dosing range to be extended. The liquid entering the container 2 through the supply pipe 3 through the inlet 4 passes through the channels 14 and the openings 8 into the cavity of the hollow perforated tube 7 of non-magnetic material. With the help of the movable electrode 16, moving in the tube in a vertical direction

The invention relates to devices for dispensing liquids.

The purpose of the invention is the expansion of diaazon dosing.

The drawing shows the dispenser, rodolnaya section.

The liquid dispenser contains a unit 1, a container 2 of a non-magnetic material, equipped with a supply pipe 3, an upper inlet 4 in the container cap and an outlet 5 in the bottom of the container. On the outer side of the vessel 2, an annular electromagnet 6 is located. Inside the vessel 2, a perforated tube 7 with holes 8 is installed, provided with ends with plugs 9 at the ends. contain a core 11 of magnetic material, and an inlet valve 12 of non-magnetic material. The valves 10 and 12 are interconnected by means of a spring 13 mounted on the tube 7. The valve 10 in its lower part is equipped with radial channels 14. The container 2 of the dispenser is equipped with signaling devices, executed in the form of electrodes 15

and 16, the first of which is installed in the bottom of the container 2, and the second is installed with the possibility of vertical movement inside the tube 7. The electrodes 15 and I b and the ring electromixes 6 are connected to the control unit 1.

The dispenser works as follows.

Dosing the liquid through the supply line 3 through the inlet port 4 enters the tank 2 of the dispenser. The outlet hole 5 is closed by the solenoid valve 10. The liquid is collected in the dispenser.

in its lower part between the wall of the container 2 and the valve 10, the liquid through the channels 14 in the valve 10 and the holes 8 enters the cavity of the tube 7.

The required volume of fluid dose is set by the movable electrode 16, which is moved in the vertical direction and sets its lower end to the position corresponding to the volume of the given dose of fluid. When the liquid level in the tank 2 reaches the level set by the electrode 16

(shown by a dashed line), the electrodes of the control unit I of the control unit I are closed through the electrodes of 15 and 16, and the electromagnet 6 and the time relay included in the control unit 1 are turned on. The valve 10 under the action of a magnetic field on the core 11 rises upwards, while the upper inlet 4 is blocked by the valve 12, which is held in this position by the spring 13. The valve 10 by the electromagnet 6, controlled by a time relay, is held for a while during which the metered dose of fluid through the outlet 5 is drained from the dispenser. The time switch turns off the electromagnet 6, the valve 10 goes down and closes the outlet 5, and the clanan 12 opens the inlet 4, the liquid enters the cavity of the container 2, and the whole process repeats again. By changing the position of the electrode 16, it is possible to adjust the volume of the dose of the dosed liquid.

The dispenser operates automatically, while providing a wide range of dosing (0.002-0.1 l), with this dosing accuracy being a composition-.

lt ± 1.5%.
