Изобретение относитс к устройствам до получени посто нных расходов жидкости .The invention relates to devices for obtaining constant fluid flow rates.

Известен стабилизатор расхода жидкости , содернсаший корпус с установленными в нем держателем .и сифоном с поплавком . ,,Known liquid flow stabilizer, sodersshiy case with a holder. And a siphon with a float installed in it. ,,

Посто нный расход жидкости в данном стабилизаторе обеспечиваетс посредством сифонно-по1шавков9го устройства, установленного подвижно в корпусе 1 .A constant flow rate in this stabilizer is provided by means of a siphon-poppet device, which is movably mounted in the housing 1.

Однако такое исполнение стабилизирующего уст|5Ойства обеспечивает равномер : ность выдачи лишь при небольших расходах , а его эксплуатаци св зана с неудоб-,5 ством запуска в работу и сложностью соединени с потребителем жидкости.However, such a design of the stabilizing device ensures uniformity of delivery only at low costs, and its operation is associated with inconvenience in starting up the operation and the complexity of connecting with the consumer of the liquid.

Наиболее близким по технической сущности к изобретению вл етс стабилизатор расхода жидкости, содержащий гер- 20 метичный резервуар со сливнь1м устройством и установленную вертикально в герметичном резервуаре трубку, верхний ко1недкоторой соединен с атмосферой 2 .The closest to the technical essence of the invention is a liquid flow stabilizer, containing a sealed tank with a drainage device and a tube installed vertically in a sealed tank, the upper one with which is connected to the atmosphere 2.

Недостатком известного стабилизатора вл етс то, что он не обеспечивает равномерного расхода всей жцдкости, наход щейс в герметичном резервуаре.A disadvantage of the known stabilizer is that it does not ensure uniform consumption of all the liquid in the hermetic tank.

Цель изобретени повышение точности стабилизатора.The purpose of the invention is improving the accuracy of the stabilizer.

Указанна цель достигаетс .тем, что в стабилизаторе расхода на дне герметичного резервуар вьшопнена выемка, в которой установлен нижний конец трубки, на котором на уровне дне герметичного резервуара вьшсвшены отверсти , а сливное устройство установлено на дне герметичного резервуара.This goal is achieved. In the flow stabilizer at the bottom of the sealed tank, a recess is installed, in which the lower end of the tube is installed, which has holes at the bottom of the sealed tank, and the drain device is installed on the bottom of the sealed tank.

На чертеже изображен стабилизатор расхода жидкости.The drawing shows the stabilizer fluid flow.

Claims

The fluid flow stabilizer contains a hexagon tank 1, in the upper part of which an air valve 2 is installed. A tube 4 is attached to the neck 3 of the sealed tank, and a drain device 5 is attached to its ZESH tube. The tube 4 is uncovered for the entire height of the sealed tank and its lower end. The device is installed in a spherical recess fc and has openings 7 located at the level of the bottom of the sealed tank, which allows full use of the volume of the sealed tank. The device works as follows. To fill the tank 1, shut off the drain device 5 and wash down the liquid through the neck 3 into the tube 4. The liquid enters the tank through the lower end of the pipe and the holes 7, displaces air from it through the air valve

2. Dip the dispensing fluid open the drain device 5. A vacuum forms between the upper level of the liquid and the upper part of the tank. A pressure difference is created, under the action of which the fluid in tube 4 is moved to reservoir 1. As soon as the level of the bone in tube 4 drops to the openings 7, air bubbles enter the reservoir 1 and through the fluid volume they rise to its upper part - the pressure is balanced (the start of operation of the vacuum regulator). At the moment of equilibrium of the pressures, the aperture 7 instantly overlaps with liquid. At the same time, the drainage forces outflow of the overflow device 5 and the vacuum process re-forms in the upper part of the tank and re-forms. The change in pressure occurs almost instantaneously, without interrupting the flow of fluid. At the level of the vacuum regulating holes 7, an equal pressure plane is formed during the operation of the vacuum regulator. At each point of this plane, the pressure is composed of the height of the liquid supply and the magnitude of the vacuum in the upper part of the tank. As the fluid is dispensed, the magnitude of the pressure of the height of the water column and the magnitude of the vacuum change in reverse, but their sum remains constant and is approximately equal to the atmospheric pressure at each point of the plane of equal pressure. The distance difference between the plane of equal pressure and the level of the lower section of the drain device 5 is also constant and does not depend on the pressure of the water column; a plane of equal pressure and liquid level in the reservoir. Therefore, the liquid is discharged from the reservoir as if from a single level with a constant flow rate. Making a part of the bottom of the tank at the installation site of the pipe in the form of a spherical recess allows the entire volume of liquid to be discharged at a constant rate. The flow rate stabilizer provides a more uniform flow of fluid. Claims of Invention A fluid flow stabilizer comprising a sealed tank with a drain device and a tube installed vertically in a sealed tank, the upper end of which is connected to the atmosphere, characterized in that, in order to improve the accuracy of the stabilizer, a recess is formed at the bottom of the sealed tank. the lower end of the tube is installed, on which holes are drawn at the bottom of the sealed tank, and the drainage device is installed on the bottom of the sealed tank.
