Abstract

The invention relates to instrumentation and allows automation of the dosing process. In the high-pressure pipe 3, an open vessel 12 is placed with a gap, attached below the iK to the shut-off member of the exhaust valve 5. In the process of filling the tank 1 with the liquid through the inlet valve 2, the floating float 9 contacts the stop 11, ensuring through the lever system 8 the opening of the exhaust valve 5. The dosing fluid filling vessel 12 flows out of it into the gap between the shank of the pop-up dump 13 and the hole in the bottom of the vessel 12. The closure of the nozzle 3 is provided by the float 10, the bottom surface of which is made sealing against the bottom of the vessel 1. The area of the open portion of the vessel 12 exceeds the area of the exhaust valve closure member 5. 1 ZP f-ly, 3 ill. with $ (L

The invention relates to instrumentation and can be used in the chemical, food and other industrial sectors.

The purpose of the invention is to automate dosing.

Fig. 1 shows the dispenser for liquids in the filled state; figure 2 - the same, when draining the liquid; on fig.Z - section aa in figure 2.

The liquid dispenser contains a tank 1 with inlet 2 fixed at the bottom and 3 outlet pipes equipped with corresponding valves 4 and 5 with rods 6 and 7, connected between each other by a lever system 8 and passed through tank 1, in which two floats 9 and 10 are placed, for one of which, a stop 11 is fixed to the stem 6 of the inlet valve 4. An open vessel 12 with a hole in the bottom is placed with a gap in the outlet and attached to the stop valve of the exhaust valve 5 from below, and the open part of the vessel 12 exceeds the area shut out Body exhaust valve 5. Shutoff valve bodies 4 and 5 are arranged in nozzles 2 and 3, the floats 9 and 10 are mounted on valve stems 4 and 5 to be vertically movable and the lower surface of the exhaust valve of the float 5 is capable of sealing against the container bottom. In the open vessel 12 introduced the float 13 with the shank, which is passed through the hole in the bottom of the vessel with a gap.

The dispenser works as follows.

Due to the fact that the weight of the intake valve 4 is greater than the weight of the exhaust valve 5, the vessel 12 with the float 13, the inlet valve is open and liquid enters the vessel through it, as a result of raising the level in the vessel the floats 9 and 10 float, and as a result of the interaction of the float 9 with an emphasis 1 1 the rshazhna system 8 provided. closes the intake valve 4 and the opening of the exhaust valve 5. The discharge of the metered liquid begins, which, once in the open vessel 12,

determines the state of the exhaust valve in the open state. The float 13 in the open vessel 12 floats up and the liquid flows through the gap between the shank of the float 13 and the hole in the bottom of the vessel 12 into the outlet nozzle 3. As the liquid flows out of the tank 1, the floats 9 and 10 lower, and the float 10 after reaching the bottom of the tank 1 along sealing connection of its lower surface with the bottom of the container provides closure of the outlet of the outlet. The fluid continues to flow from the cavity of the outlet and the open vessel through the hole in its bottom. After the discharge is completed, the weight of the valve 5 with the vessel 12 and the float 13 is lower than the weight of the valve 4, which determines its opening, i.e. the beginning of the next tank filling cycle 1.
