Description

The invention relates to devices for automatic metering of a liquid by weight values - weight liquid dispensers, in which the distribution valves are controlled by an electromagnet, the circuit of which closes when the liquid reaches the highest and the lowest level.

The proposed apparatus for dispensing a liquid, made in the form of an intermediate measuring tank with the use of filling and drain valves, has the difference 1 that a liquid pressure gauge connected to the bellows installed at the bottom 3 of the measuring tank is used in the automation slot for controlling the electromagnet circuit breaker.

The drawing shows a diagram of the proposed dispenser.

The liquid to be dispensed comes from the distributing reservoir through pipe 1. Turning the tap 2 opens the access of the fluid through the chamber 3, in which the double-sided ball is placed: valve 4, into the reservoir 5. Turning the tap 2 simultaneously switches on the current, which is used “Other operations. Before turning up valve 2, therefore, open the access of fluid to tank 5 and turn on so that regulator 6 by turning dial 7 sets its arrow so that it coincides with the number on the scale 8 indicating the quantity of liquid needed for dosing. The rotation of the dial 7 moves in the vertical direction the contact 9 inserted into the U-shaped tube 10 filled with mercury. The second contact 11 of the electrical circuit is inserted into the U-shaped tube 10 iB of its lower part and is in constant connection with mercury.

After turning. 2, the liquid begins to fill the reservoir 5 and, with its weight, connect 1 to 1 in 1 to the assembled bottom of the reservoir, the sylphon 12, filled in turn with a heat-resistant liquid. The pressure of the liquid column filling the reservoir 5 causes the bellows 12 to compress in the axial direction and thereby displace the fluid inside the bellows through the tubes 13 and 14. On the one hand, moving the tube 14 the action of the pointer of the indicating device 15, and on the other hand, moves the mercury, which, detaching itself from the contact 16, opens the circuit, preparing the self connected in the circuit, the relay 17 to the next operations. As a result, all merging pressure of mercury comes, and rings, into the base with cycle number 9. Thus, the mercury column connects pins 9 and 11 of VJ, thus closing the circuit with relay 17 inserted into it. leads electromagnet 19 into operation in chamber 20. A servo plate of electromagnet 19 uses lever 21 to actuate a ball valve 4. When the tank 5 is filled with liquid, the upper filling opening of the chamber is open and the lower drain opening of the chamber is closed with a ball 4 . Etc and discharging the measured liquid from tank 5, valve 4 opens the drain hole of the chamber 3 and closes the filling liquid.

As the fluid flows out of the reservoir 5, its pillar, which exerts pressure on the bellows 12, decreases, and the bellows, respectively, which relieves pressure, gradually returns to its original position, and the filling fluid and the tubes 13 and 14 of the thermal fluid move towards the bellows 12, weakening at this pressure the pressure exerted earlier through the tube 14 on the mechanism of the no-quoting device 15 and “ia mercury.

At the moment of complete emptying of the reservoir 5, the bellows 12, and together with it; the liquid and the mercury fill the tubes 13 and 14, (return to the initial position, the arrow of the indicating device 15 takes the position 10, and the mercury goes into contact with step 16, closes the circuit and leads the action to include the relay 17. This circuit de-energizes the electromagnet 19, and the spring 22 accepts 3 Action ball valve 4, which, closing the opening of chamber 3 with the lower ball, simultaneously opens the upper opening of this chamber 5 fluid.

This ends one and begins the second cycle of operation of the pattern. The number of such CYCLONE is counted on a special counter 23, which allows the dispenser to remain operating for a long period of time without observation. The operation of the meter & ket is also performed with the help of relays that receive a pulse FROM photocells.
