Description

Изобретение относитс к автсматическому управлению и может быть использовано в системах пневмоавтсма-; тики.;The invention relates to automatic control and can be used in pneumatic systems; tiki .;

По основному авт.св. № 798740 известен струйный регул тор расхода, содержащий корпус с входным каналом, соединеннымс соплом, выходной, канал , расположенный соосно с соплом, и ко.льцевую камеру управлени , соединенную с соплом через кольцевую п;е.пь, причем внутренн поверхность сопла выполнена в виде выпукло криволинейной поверхности вращени , а ко.льцева щель расположена тангенциально к внутренней поверхности сопла 13According to the main auth. No. 798740 is well known for an inkjet flow regulator, comprising a housing with an inlet channel connected to the nozzle, an outlet channel aligned coaxially with the nozzle, and a control chamber connected to the nozzle through an annular n; e; as a convex curvilinear surface of rotation, and the co-fissure gap is located tangentially to the inner surface of the nozzle 13

Недостатком известного устройства вл етс узкий диапазон регулировани , обусловленный отсутствием органов воздействи на характеристику регул тора.A disadvantage of the known device is a narrow control range, due to the absence of organs affecting the characteristics of the regulator.

Цель изобретени - расширение диапазона регу.лировани .The purpose of the invention is to expand the range of regulation.

Поставленна цель достигаетс тем, что регул тор снабжен дополнительной кольцевой камерой управлени , соединенной с соплом через дополнительную кольцевую , при The goal is achieved by the fact that the regulator is provided with an additional annular control chamber connected to the nozzle via an additional annular

этом кольцевые щели направлены навстречу друг другу.This annular gap directed towards each other.

Изменение давлени в дополнительной камере управлени позвол ет воздействовать на характеристики регул тора, расшир тем сгшьм диапазон регулировани .The change in pressure in the additional control chamber allows you to influence the characteristics of the regulator, expanding to increase the control range.

На чертеже общий вид пред10 лагаемого устройства, разрез. In the drawing, a general view of the proposed device, section.

Струйный регул тор расхода оостоит из корпуса 1 с соосно расположенными в нем входных 2 и выходньм 3 каналам, св занными соплом 4. В The jet flow regulator consists of a housing 1 with inlet 2 and 3 outlet channels coaxially arranged in it, connected by a nozzle 4. In

- 15 корпусе 1 имеютс кольцева камера 5 управлени дл подачи потока управлени через канал 6 и дополните .пьна кольцева камера 7 управле- ни дл подачи потока управлени - 15 casing 1 has an annular control chamber 5 for supplying control flow through channel 6 and add more control valve to the annular control chamber 7

20 через канал 8. Камера .5 и дополнительна камера 7 св заны с соплом 4 с помощью кольцевой ще.ли 9, направ-, ленной вдоль основного потока, и дополнительной кольцевой щели 10, нап25 равленной навстречу основному потоку. Внутренн поверхность выходного канала 3 - выпукла криволинейна поверхность вращени , образующа продолжение внутренней поверхности 20 through the channel 8. The chamber .5 and the additional chamber 7 are connected to the nozzle 4 by means of an annular gap 9 or 9, directed along the main flow, and an additional annular gap 10, which is opposite to the main flow. The inner surface of the output channel 3 is a convex curvilinear surface of rotation, forming a continuation of the inner surface.

Claims

30 nozzles 4. On the line of action of the jets from the output channel 3, a nozzle 11 is installed therewith. The device operates as follows. The channel 2 of the housing 1 is supplied with working medium, which flows through the nozzle 4, flows into the output channel 3, and then into the receiving nozzle 11. At the same time, the flow of control channel 8 into the chamber 5 and, independently, through the additional chamber 7. These flows through the annular slots 9 and 10 go out into the nozzle 4 towards each other. The presence of a counter flow control / feed through the annular gap 10 inhibits the main flow of the working medium, due to which the effect of flow control increases with less control air consumption. The presence of an additional chamber 7 and an additional annular slit 10, as well as an independent flow of controlled flow through them, makes the control characteristic flexible. By making the output channel 3 in the form of a convex curved surface of rotation which is a continuation of the I surface of the nozzle, control flow streams envelop the surface of the output channel 3, forming a control flow layer practically on the mixing flow of the pine flow when entering the receiving nozzle II. The use of a counter-flow in the proposed jet flow rate regulator can significantly improve the quality of controlling the flow rate of a liquid or gas. Claims of invention Inkjet flow rate regulator according to author. No. 798740, in order to expand the range of adjustment, it is equipped with an additional annular control chamber connected to the nozzle through an additional annular slot, with the annular: slots facing each other.
