Abstract

The invention relates to a dosing technique and can be used, for example, for dispensing chemical reagents. The aim of the invention is to increase the reliability and accuracy of dosing. The liquid is packed through the vertical channels 2 of the slots 3 of the housing 1 through the holes 18 and 7 into the cavity of the housing I, filling the chamber of the housing 1, the liquid enters the measuring cup 20 to the level set in the tank, while the dose is adjusted by the propellant 2, while lifting the rod 4 under the action of the incoming vial, the valve 10 rises and closes the vertical channels 2. After further raising the stem 4, the opening 8 enters the chamber chamber J and the liquid is drained into the vial, silt. (ABOUT

The invention relates to a dosage technique and can be isiol 13ow Io, for example, for dispensing chemical reagents.

The aim of the invention is to increase the reliability, accuracy of dosing and the possibility of dosing various liquids.

i The drawing shows the proposed device.

1The device consists of a housing 1, connected by vertical channels

2 with side slits 3, located in it, a spring-loaded stem 4: about a drain channel 5 divided by a partition 6, on both sides of which holes 7 and 8 are formed for the first fluid passage installed on the valve 4 and located over it additional valve 10 with emphasis

1.1 and spring 12, centering the bell 3 with channel 1A,

To seal the case, the connector is 1 & H with a diaphragm 15 with a stem 4, and the last 16 17 for air outlet and the holes 18 and 19 for H1-SCALE are formed. The displacer 21 is installed in the measuring cup 20,

The device works as follows

 From the reservoir of the liquid filling machine, the packaged product through the vertical channels 2 of the slots 3 of the core 1 enters through the holes 18 and 7 into the chamber of the housing 1, the air is expelled through the hole 16. After filling the chamber of the housing 1, the product enters the measuring cup 20 to level installed in the reservoir of the automaton: the dose is adjusted by the exciter 21, the vial lifted by the automaton table rests against the centering bell 13 and raises the stem 4. At the first stage of the movement, the valve 10 closes the vertical channels 2 slots 3, to measure the lifting of the stem 4 by strengthening the clamp due to the reduction of the spring 12 to the specified value: After closing the channels of the side slots 3 with the valve 10, the stem 4 lifts

Ipeps at the entrance of the opening 8 into the chamber of the housing 1. In this position, the product dose is drained into the vial, the air from which is expelled and exits through the channels 14 of the bell 13. The opening 17 is under the valve O and, when the appropriate level of liquid is reached, provides air to the chamber housing 1, thereby maintaining flow stability and complete emptying of the chamber. The fluid that enters the space bounded by the diaphragm 15 is discharged through the opening 19. The diaphragm 15 itself seals the body chamber during the dose draining period. After the dose is drained, the table of the vending machine is lowered. The stem 4 is also lowered under the action of the spring 22, the valve 9 closes the connection between the drain holes 7 and 8, and then the valve 10 moves away from the vertical channels 2 of the side slots 3. From this moment the next filling of the dispenser begins, and then the dosing cycle is repeated.
