With ioxc and iocti, decrease: and the reagent consumption to drive the peristaltic pump 3 through the control unit 10 is given an electrical signal 3 ensuring its counterclockwise rotation.

The valve is opened by applying an electric signal to the ijaco-ca actuator, in which its rotor rotates clockwise. A portion of the working fluid is pumped out of the control cavity into the container due to the ability of the pressure in the control cavity, the plunger rises, and the flow cross section of the reagent is increased and the flow rate increases.

the error signal between the specified n actual costs.

Increased operational reliability (the device is provided by the shape of the bore section of the seat (equilateral triangle) and the corresponding plunger profile (canted triangular prism). With this shape, the maximum inscribed circumference is achieved, which corresponds to a lower probability that the valve-metered dose channel is blocked by solid particles present in the solution. The maximum plunger stroke is determined by the material and construction of the membrane.

Invention Formula one . A device for dispensing flotation reagents, containing a reagent tank, a reversing multi-turn actuator, an associated control unit and a metering valve divided by a membrane with a plunger mounted on its center into two chambers - a control and a working one, the inlet of which is connected to the pipeline reagent tank, and a calibrated seat is installed in the output coaxially to the plunger, which is due to the fact that in order to increase operational reliability and simplify the device, made in the form of an equilateral three-35 perforated sleeve with the possibility of a faceted prism, which is accelerated in one translational movement itself from the corners, and the area and configuration of the sleeve is rigidly fixed in the control hole in the saddle chamber coaxially with the plunger. 07 At the same time, the operating mechanism is equipped with a rotor mounted gun / 1b m on its shaft, with different i-; a circumflex circle in which, no less than three, on which is installed, ynpyrnii uuiaer, one end of the connection; 1vv with control camera the valve 5 and the other connected to the vessel with the working fluid. 2. The device according to claim 1, characterized in that, in order to linearize the flow characteristic, depending on the movement of the plunger, its bevel profile is made in accordance with the dependence - plunger thickness as a functor of its displacement, MMJ K is a constant, depending on the maximum throughput of the valve and the pressure; at its inlet, mm; Y. - is full of the profiled part of pa, mm. 3.
