Description

(54) LIQUID FLOW REGULATOR

one

The invention from 1 / osit to the field of automatic control and can be used to automatically maintain predetermined flow rates of liquids.

Fluid flow controllers are known that contain a membrane or bellows coupled to a supply pipe and a control valve mounted on the supply pipe.

However, these controllers are distinguished by design complexity and insufficient regulation accuracy due to mechanical connections of the elements.

A device for regulating the flow of a liquid by means of a thermoelectric battery is known.

This device is the closest to its technical nature of the invention. It contains a thermoelectric battery, the tapes of which are installed on the feeding pipe.

installed in the pipeline controls the current supply to the thermoelectric battery. When the thermoelectric switch is turned on, the liquid in the pipeline freezes, forms

the ice plug and the liquid supply is stopped. When the thermoelectric switch is turned off, the ice on the plug melts and the fluid supply resumes. With this device it is impossible to automatically adjust the smooth. fluid flow due to the positional mode of operation of the controller.

The purpose of the invention is to simplify the design and increase the accuracy of the controller. This is achieved by the fact that the code of the supply pipeline is connected to an additional pipeline on which the heat-generating junctions of the thermoelectric battery are installed.

In the drawing, the design of the regulator is given.

The regulator consists of thermoelectric battery 1, heat-absorbing junctions 2 of which are installed on supply pipe 3, which is connected to heat supply section by means of secondary pipe 4 of thermo electric battery 1 by means of auxiliary pipe 4 and supply pipe 3 and 4 are equipped with valves 6 and 7.

The regulator works as follows. With the inclusion of thermo-lactating 1

A layer of crystalline liquid, for example ice, is formed in the supply line 3. The required thickness of the ice layer, which determines the required water supply, is established by changing the current supplying the thermoelectric battery 1. The water supply can also be adjusted by means of the valve 6. Part of the water through the additional pipe 4 is fed to the cooling of the thermal melts of the junctions 5 of the thermoelectric power 1. Supply of the same part water is regulated | valve 7. With a constant supply of stabilized power supply to thermoelectric battery 1 section for the passage of water in the supply pipe 3 is constant. When amening water supply, for example, when it decreases, the heat output of the junctions 5 deteriorates with cooling condition, the cooling capacity of thermoelectric battery 1 decreases, some of the ice melts, the water for itipox.oau increases and the water supply increases. With an increase in water supply, the cooling capacity of thermoelectric battery 1 increases due to more intensive cooling of heat-generating junctions, the ice layer increases, narrowing the cross section for the passage of water, and the water supply decreases.

Thus, by introducing an additional pipeline and connecting it with a thermoelectric battery, the incompatibility in complex mechanical and electronic control systems is eliminated to ensure accurate flow of the fluid being pumped.
