SU1541185A1 - Apparatus for dispensing liquid - Google Patents

Abstract

The invention relates to the technique of dosing liquids and can be used, for example, for the subsoil application of liquid organic fertilizers. The aim of the invention is to ensure uniform distribution of fluid as the tank is emptied. The safety valve 4 is calibrated for the actuation pressure, which ensures the required flow rate at the initial moment of the device operation. Compressed gas is supplied to the tank 1 filled with liquid through the pipe 3. When opening the valve 13 on the nozzle 2, as the fluid flows out of the tank 1, the pressure in the tube 6 drops. At the same time, the diaphragm bends, pulling the rod 10 of the lever mechanism 8, which acts on the safety valve 4 through the rack 9 and the rod 11, changing the response pressure valve 4 in the direction of large values. Thereby, the gas pressure in the supra-fluid cavity 5 increases in proportion to the amount of liquid dispensed. 1 il.

device.

A device for dispensing a liquid from the supply tank 1 with a pipe 2 to drain the liquid, a pipe 3 for supplying compressed gas and a safety valve k mounted in the supra-fluid cavity 5 of the tank 1, as well as a gas-pressure regulator in the supra-fluid cavity 5 including a tube 6, installed in front of the pipe 2 of the liquid outlet and fixed on the inside of the super-ductile cavity 5 of the tank 1, and the membrane 7 installed in the upper end of the tube 6 and connected to the safety valve k by means of a lever th mechanism 8.

The lever mechanism 8 includes a stand 9 on which the rod 10 is attached, connected to the diaphragm 7 and the rod 11 connected to the safety valve 4, and a spring 12 with which the safety valve Ts is calibrated. To close the pipe 2 to drain the liquid. .

The device works as follows.

The safety valve k is calibrated by means of a spring 12 to the actuating pressure, which ensures the required flow rate at the initial moment of operation of the device. 6, the reservoir I, filled with liquid, is supplied through the nozzle 3 with compressed gas, for example, 45 exhaust gas from the engine 30

rack 9 and rod 11, changes the response pressure of the safety valve by k in the direction of larger values. T the most gas pressure in the supra-fluid cavity 5 increases in proportion to the amount of fluid dispensed, h ensures uniform distribution of the bone as the tank 1 is empty.

The use of the proposed device for dispensing a liquid, for example, subsurface application of liquid organic fertilizers, allows savings due to the rational use of fertilizers.

invention formula

A device for dispensing a liquid, containing a supply tank with a pipe for discharging the liquid, a pipe for supplying compressed gas and a safety valve mounted in the chest cavity, which is intended to ensure that the liquid is evenly dispensed as the tank is empty it is equipped with a pressure regulator in the supra-fluid cavity, consisting of a tube installed opposite the cutting chamber and fixed on the inner side of the supra-fluid reservoir, and a membrane installed in the upper end of the tube and one with the safety valve through the lever mechanism

rack 9 and rod 11, changes the opening pressure of the relief valve k in the direction of larger values. Thereby, the gas pressure in the supra-fluid cavity 5 increases in proportion to the amount of liquid dispensed, thus ensuring that the liquid is evenly discharged as the reservoir 1 is empty.

The use of the proposed liquid dispensing device, for example, the sub-application of liquid organic fertilizers, results in savings due to the rational use of fertilizers.

invention formula

A device for dispensing a liquid, containing a supply tank with a pipe for discharging liquid, a pipe for supplying compressed gas and a safety valve mounted in the suprafluid cavity of the tank, so that, in order to ensure uniform distribution of the liquid as the tank is empty, it is equipped a gas pressure regulator in the supra-fluid cavity, consisting of a tube installed opposite the liquid outlet nozzle and fixed on the inner side of the supra-fluid cavity of the reservoir, and a membrane, constant in the upper end of the tube and connected to the safety valve through the link mechanism.
