Description

Instruments for pouring liquids in definite doses are known, consisting of two alternately filled and dispensed vessels and a metering tank fed from a supply tank by means of a siphon.

In the proposed device, the dosing reservoir is hermetically closed and installed between the supply tank and the liquid dispensing vessels; On the purpose of creating a vacuum. Inside the metering tank, it is equipped with a hose with a tap.

The drawing shows a vertical section of the device.

The non-proposed instrument consists of two or several measuring cylinders A connected through a multi-way valve D with a hermetically sealed metering tank B. The latter, using a siphon tube B G Crash H, communicates with tank G for the liquid to be measured. The said reservoir consists of a hermetically sealed vessel having three tubes in the cap, one of which, reaching almost to the bottom, is an extension of the siphon tube B; the second, which also reaches almost to the bottom, when exiting tank G, ends up with a funnel-shaped extension C, and the third, which is short, ending with tank head G, is equipped with a tap II (outside tank G). Dosing resedauao B, for the purpose of sodolnomuyuschim pipe with hose E, having a valve F with a mouthpiece.

The device is operated as follows. Mouth (go with the reverse end of the rubber spray gun), through the mouthpiece of the tube E, with open spots N and I and the closed tap II, suck the air to those shor until one of the cylinders A is filled (through the vessel B) to the desired desired division. After that, the valve G is closed and the tube. stays idle until the end of the entire work of marking.

By turning the tap D, the contents of the cylinda A tilts to zero in the bottle /, and during this time another cylinder A has time to be filled. Each next one. turning the crane will mechanically repeat this operation a limited number of times.

When tank T is filled, you must first close the k.ran N, then open the spot I and fill tank G through the pile C. After filling (not up to the top) of the vessel, you must suck out the air through the rubber tube at the tap I until bubbles start exit through the tube C in the tank G; it is necessary to close the edge I and only then open the tap I

To switch the device to measure other than the amount of liquid before, you must first turn off the tap I, then open the tap J and DOWOM kn. / 7 cmrRwtT. vnATJAtit. p poodp

sti in the cylinder; But it lowers to the required deletion, after which the valve W is closed or sucked again through the mouthpiece of the valve W so much air that the fluid level (with the stationary crane D) in cylinder A raises to the required division.

In order to clean the system of vessels A and B from escaping at the end of all work, before switching to measuring another%, it is necessary to close the tap I and, Sucking air through the mouthpiece of tap G, concentrate all residual liquid from cylinders A and all tubes into tank B , and the last to empty through a tube in its lower stopper. The subject matter of the invention.

A device for dispensing liquids in definite doses, consisting of two alternately filled and emptied VASKS and a dozing reservoir, is fed from the supply tank by means of a siphon, characterized in that the metering, hermetically sealed rezovuar B is installed between the supply tank and the vessels dispensing the liquid for the purpose of creating an additional vacuum inside: a branch pipe, with an E-hose with a tap.
