Devices for measuring predetermined amounts of liquid using a measuring vessel, which is periodically filled with liquid coming from the tank and emptied, are known.

The peculiarity of the proposed device is that it uses two partially communicating vessels, one of which is suspended and connected to the cavity of the measuring vessel, and the other to move in height, and depending on its descent it is poured a smaller part of the liquid from the stationary vessel, creating a vacuum in it and in the measuring vessel connected to it, so that depending on the degree of resolution it is possible to establish the amount of liquid measured ,. sucked into the measuring vessel from the tank.

FIG. Figures 1 and 2 show the proposed device in two projections.

The liquid storage tank consists of a body / tube 2 that maintains the level of the liquid in the measuring vessel at the level of the drain valve b, gauge glass 4 and the i-epMetic plug 3. The tank is connected to the measuring vessel with a Yu pipe with a crane.

Measuring vessel 5 is connected to vessel 8 by tube i / and vessel S is connected by flexible hose 5 to moving vessel 7. Vessel 7 by thread 22 through rollers 16 and 21 can be turned by turning knob 19 connected to scale 15 and roller 2 /. way down. The process of measuring the fluid is as follows.

Before weighing, the main tank 1 is filled with liquid, which from tank 1 enters measuring vessel 5, and is installed at the level of drain valve 6.

For the production of measurement, measuring vessel 5 is connected to vessel S, previously filled with any kind of liquid. After that, the dial / 5 is turned by the knob 19 until the division of the scale with the number indicating the number of fluids is set against the pointer 14.

When the scale 15 is rotated, the vessel 7 is lowered and the liquid from the vessel 8 is poured into it. At that, m in the vessel 5 and in the measuring vessel 5 a vacuum occurs and the measured liquid from the tank / enters the measuring vessel 5.

When the hydrostatic pressure in the tank in the measuring vessel 5 is reduced, the drain valve is opened 6 and the valve on the tube 10 is closed. The measuring vessel 5 is disconnected from the vessel 5, which is first connected to the atmosphere (everything is mechanically connected between what is not shown in the drawing). When this fluid from the vessel 5, will flow out. To measure the next batch of liquid, the handle 19 returns the entire system to its original position.

Claims (2)

1. A device for measuring the prescribed amounts of a liquid using a measuring vessel, into which the liquid flows from the bait F   r rm gut ka, which is distinguished by the use of two communicating vessels partially filled with any liquid, one of which is fixed and connected to the cavity of the measuring vessel, and the other can be moved in height so that, depending on whether it is lowered, more or less from a stationary vessel, creating in it and in a measuring vessel connected to it a vacuum with a view to depending on the degree of vacuum it is possible to determine the amount of liquid sucked into a smaller vessel of the tank when connecting the opening of the faucet. 2. The form of the device according to claim 1, characterized in that the device for lowering the moving vessel is equipped with a scale calibrated directly in the values; the quantities of fluid that need to be measured.
