Embodiment Construction

[0025] figure 1 Shown is a mixing system 1 for mixing chemical products such as phytosanitary products with water. The system 1 comprises a water inlet 3 suitable for connection to a pressurized water inlet such as a sprinkler hose. The system 1 also includes a chemical product inlet 5 suitable for connection to a chemical storage tank. Finally, the system 1 also comprises a mixture outlet 7 through which the mixture of water and said chemical product can be directed, for example, to a spray hose or a product nozzle.

[0026] The system 1 comprises a main pipe 9 arranged between the water inlet 3 and the outlet 7, in which main pipe the water flows in the direction of the arrow F1. The upstream side of the system 1 is located on the side of the water inlet 3 , and the downstream side is located on the side of the outlet 7 , and the upstream and downstream sides are defined relative to the direction of water flow in the main pipe 9 .

[0027] The system 1 comprises a main ch...

Abstract

The invention relates to a device for controlling the flow of liquid in a tube comprising a hollow body comprising an inlet and an outlet between which liquid can flow. The control device includes at least one adjusting element rotatable in the hollow body, the adjusting element includes a plurality of turntables that rotate together with each other, and each turntable has a plurality of holes with different diameters. Said device comprises an intermediate disc fixed relative to said adjustment element and interposed between said turntables, said intermediate disc being perforated with at least one hole. The adjustment element is adapted to be turned so that one of the holes of the turntable is opposite the hole of the intermediate disc.

Description

technical field [0001] The invention relates to a control device for regulating the flow of a liquid, and a mixing system for mixing a chemical product with water comprising the regulating device. Background technique [0002] The regulating devices of the liquid flow known in the prior art do not allow to obtain precisely adjustable low liquid flow rates, especially in the case of spraying phytosanitary products mixed with water in very precise concentrations. Contents of the invention [0003] More specifically, the present invention aims to solve the above-mentioned drawbacks by proposing a novel device for controlling liquid flow, which allows high precision regulation of small liquid flows. [0004] To this end, the invention relates to a device for controlling the flow of liquid in a tube, comprising a hollow body comprising an inlet and an outlet between which the liquid can flow. The control device includes at least one adjusting element rotatable in the hollow bo...
