SU1408230A1 - Metering tank - Google Patents

Abstract

This invention relates to a measurement technique and makes it possible to exclude carbonated 1e metered liquid. The hermetic tank 1 is divided by an impenetrable partition 5 into two cavities interconnected in the upper part. The upper end of the baffle 5 is located above the level of the liquid to be dosed 2. From the tank, the liquid flows out through a siphon tube 3 made with a small diameter. Air tube 4 and tube 3 are located in different cavities. The tube 3 can be installed with a possible reciprocating movement. 1 il.

The invention relates to dosing devices and can be used to dispense various liquids.

The aim of the invention is to prevent gassing of the metered liquid.

The drawing shows the dispenser Liquid, rbsky view. ; The dispenser, the liquid contains an airtight container 1 with the dispensed liquid 2 provided with an outlet nozzle in the form of an oyphon tube 3, an air tube 4, one end of which is located below the liquid level and the other with the atmosphere. The dispenser is provided with an impenetrable septum 5 dividing the container into two cavities communicated with each other in the upper part, the upper end of the septum being located above the level of the dispensed liquid, and the ends of the siphon and air tubes are placed in different cavities. The siphon tube is made in a small diameter tube.

I The liquid dispenser works in the following way.

I When preparing for operation, a slight overpressure iS is applied to the hermetic tank 1. This increases the hydrostatic pressure, under the action of which | the liquid from the tank 1 begins to flow through the siphon tube 3 in a drop of 1 l m.

An impenetrable partition eliminates the carbonation of the metered liquid by the air supplied through the tube 4.

To stop the flow of fluid through the siphon tube 3, the free end of the air tube 4 is closed, and the surface tension of the fluid at the lower free end of the siphon tube prevents it from flowing out.

The siphon tube can be installed with the possibility of vertical reciprocating movement. In this case, it is enough to lift the siphon tube to stop the flow of fluid.
