Description

one

The invention relates to devices for supplying a filler fluid to the main fluid flow and can be used in the chemical industry, construction, water supply systems, etc.

A known dispenser for chlorinating water, comprising a container for a filler fluid, a pressure conduit for the main fluid, a rotameter, and an ejector 1.

The closest to the proposed is a device for supplying a filler fluid to the water being treated, which contains a tank for the filler fluid with inlet, outlet and drain connections, a control valve, and a pressure pipe of the fluid being treated with a pressure gauge 2.

A disadvantage of this device is the difficulty of adjusting and controlling the operation, since it does not include adjustment elements and elements for controlling.

The purpose of the invention is to simplify the adjustment and provide visual control over the operation of the device.

This goal is achieved by the fact that the tank is equipped with a siphon tube with a rotameter and an air vent tube, and an ejector with a check valve and two control valves and a removable diaphragm are installed on the discharge pipe section.

The drawing shows the proposed device.

The device includes a container 1, a cover 2, an inlet 3, a valve 4, an air vent tube 5, a valve 6, a siphon tube 7, a valve 8, a rotameter 9, a water meter glass 10, a drain branch pipe 11, a valve 12, a branch pipe 13, a valve 14, check valve 15, ejector 16, pressure pipe 17, valves 18, 19, pressure gauge 20 and removable diaphragm 21.

The device works as follows.

The container 1 is filled through the valve 4 with an additive liquid. The filling level can be monitored using gauge glass 10. From the tank 1, the additive fluid is supplied through the outlet pipe 13 to the ejector 16 and further to the pressure pipe 17. The diaphragm 21 in the pressure pipe creates a pressure differential, under the action of which the main fluid is pumped through the ejector 16.

Claims (2)

The concentration of the additive fluid in the primary fluid is determined by the level in the tank 1, the pressure in the pressure pipe 17, the properties of the fluids, the resistance of the valves, and the diaphragm. The valves 18 and 19 regulate the flow rate of the main fluid in the ejector 16 and the flow of the filler fluid. The device can also be adjusted by means of a valve 14 in the pipeline 13 for supplying the additive fluid and changing the bore of the membrane 21. When sucking the reagent solution in the tank 1, a vacuum is created that facilitates the flow of air through the rotameter 9. The readings of the previously calibrated rotameter 9 correspond to the actual dose the reagent solution entering the treated water, and the level of the solution in the tank 1 is monitored by gauge glass 10. The application of the proposed device This will facilitate adjustment and visual control of the dosing process. 5 iO 15 20 26 Formula of the Invention A device for supplying an additive liquid, containing 1, its capacity for an additive liquid with an inlet, outlet and drain nozzles, a regulating valve installed on the outlet branch pipe, a pressure pipe of the treated liquid with a pressure gauge, characterized in that it is simplified adjusting and providing visual control over the operation of the device, the tank is equipped with a siphon tube with a rotameter and an air vent tube, and in the section of the nano pipeline of the treated liquid is us ejector with a check valve and two control valves E and the removable diaphragm.
