SU39595A1 - Liquid dispenser in modified quantities - Google Patents

Description

The device is a kind of siphon devices for dispensing liquid in measured quantities that are automatically charged when the liquid reaches the limit level set by moving the siphon knee in the vertical direction, with the siphon breaking through the use of inlet and drain liquid pipes of different cross section.

The novelty, according to the invention, is that in order to correct errors when dispensing doses of liquid observed in already known siphon devices, the measuring tank has an auxiliary intermediate tank that bypasses the liquid from the supply pipeline from the moment it starts to the end of the overflow of the measured quantity.

The proposed device consists of a tank 7, a tightly closed lid 2. The ground pipe enters this tank 3 and the pipes and the troughs 5. The pipe 3 is a siphon and reaches the bottom. It can be moved out of the tank and secured in the desired position by a nut 6 provided with a leather spacer. Into the tube 4 of the tube 7, through the valve 8, communicating with the tube leading to the liquid. Through tube 5, air is displaced during filling. Inside the tank 7

in a small vessel, a ring-shaped vessel 9 equipped with a small siphon / O (preferably several siphons from a tube, if possible with a large diameter). The tube 7 enters this ring-shaped vessel. If a uniform stream (from a tank with a constant level) is supplied through the tube 7, then when the height of the fluid in tube 4 reaches a known, well-defined level, a siphon 3 will start to act, which quickly pours liquid from the tank to the crockery. The liquid flowing during the emptying period is retained in the annular vessel 9 (which at the time of emptying by means of small siphons the JO is emptied first of all). If the device is preliminarily adjusted, retracting and extending the tube 3 to a certain volume of liquid produced (coarse adjustment is made by dividing the tube 3), then with the valve 8 in the same position, the meter will automatically eject accurate volumes of liquid for an indefinitely long time until the valve eight.

The meter can be used for measuring standard volumes: when dispensing kerosene and gasoline, when pouring beverages, tea, etc., in canteens, when pouring medicinal liquids in pharmacy warehouses, etc.

Subject and sourcing.

An instrument for dispensing a liquid in measured quantities, consisting of a tank with a self-exchanging liquid with an increase in the level of the liquid and vertically interchangeable to establish a siphon of a certain amount of liquid, differing

In order to prevent the liquid from entering the tank 7 from the supply pipe during the emptying of the tank, the latter is provided with a box P fortified at the top, connected to the liquid supply pipe 7 and the tank / siphon small pipes 10 and intended for receiving the liquid during the transfer of the measured amount of liquid from the reservoir / siphon 3.
