Abstract

FIELD: machine building.
SUBSTANCE: in an ejector-type liquid flow spreader for a nozzle, a liquid flow spreader is fixed to the end face surface of a captive nut axisymmetrically to a casing. The spreader consists of three coaxially set pyramidal shells in the form of generating grids: inner, intermediate and outer ones. Each of the shells comprises a wire frame from two bases of square shape and lateral edges of a truncated pyramidal surface. The outer shell is fixed to the casing by the bigger base. The second base of the shell, the smaller one, is simultaneously the bigger base of the intermediate shell with lateral edges. The smaller base of the intermediate shell is simultaneously the bigger base of the inner shell with smaller base. The generating grids in the form of truncated pyramidal surfaces are arranged so that all their vertices lay on the axis coinciding with the casing axis. The direction of the vertices of the outer and the inner generating grids is the same. The vertex of the intermediate generating grid is counter directed in relation to the vertices of the outer and the inner generating grids to the side of a throttling orifice with a jet.
EFFECT: higher efficiency of liquid atomising.

Description

The invention relates to techniques for spraying a liquid.

The closest technical solution to the claimed object is a liquid flow divider according to patent RU No. 2450837, А62С 31/02 (prototype), containing a hollow cylindrical body with a throttle washer connected to a union nut to which the liquid flow divider is mounted, made in the form of two in series connected meshes, one of which has the shape of a circle, and the other hemisphere.

The technical result is an increase in the efficiency of fine atomization of a liquid.

This is achieved by the fact that in the ejection-type liquid flow divider for the nozzle, which contains a hollow body, consisting of a cylindrical part with an external thread for connecting to the nozzle of the distribution pipe for fluid supply, and a union nut fixed to the lower part of the body with the liquid flow divider, and a cylindrical hole is made coaxially to it in the housing, in the upper part of which a strainer is installed, and in the lower part - a throttle washer with a nozzle, to the end surface of the axle nut The flow splitter is mounted metrically to the body, which consists of three coaxial coaxially arranged pyramidal shells in the form of generating grids: external, intermediate and internal, each shell containing a wire frame of two bases in the form of a square and side edges of a truncated pyramidal surface, while the external the shell is attached with a large base to the body, and its second, smaller base is simultaneously a large base of the intermediate shell with side ribs, and its smaller base At the same time, the base is the large base of the inner shell with a smaller base, and the generating grids in the form of truncated pyramidal surfaces are located in such a way that all their vertices lie on the axis coinciding with the axis of the housing, the direction of the vertices of the external and internal generating grids coincides, and the vertex of the intermediate generating the grid is directed opposite to the vertices of the external and internal generating grids, and toward the throttle washer with a jet.

In Fig.1 presents a diagram of a divider flow of liquid ejection type assembly with a nozzle, Fig.2 is a General view of the divider.

An ejection-type liquid flow divider for a nozzle, which contains a hollow body 1, consisting of a cylindrical part with an external thread for connection to a nozzle (not shown) of a distribution pipe for fluid supply, and a union nut 6 fixed to the lower part of the body with a fluid flow divider 7. In the housing 1, a cylindrical hole 2 is made coaxially with it, in the upper part of which a strainer 4 is installed, and in the lower part there is a throttle washer 3 with a nozzle 5.

A divider 7 is mounted axially symmetrically to the housing 1 to the end surface of the union nut 6, which consists of three coaxial coaxially arranged pyramidal shells 8, 9, 10 in the form of generating grids: external 8, intermediate 9 and internal 10. Each of the shells contains a two-base wire frame in the form of a square and side edges of a truncated pyramidal surface. The outer shell 8 with a large base is attached to the union nut 6, and its second, smaller base is at the same time the large base of the intermediate 9 shell with side ribs, and its smaller base is simultaneously the larger base of the inner 10 shell with a smaller base. Generating grids in the form of truncated pyramidal surfaces are arranged in such a way that all their vertices lie on an axis coinciding with the axis of the housing 1, and the direction of the vertices of the outer 8 and inner 10 of the generating grids coincides, and the vertex of the intermediate 9 generating grid is opposite to the vertices of the outer 8 and inner 10 generating grids, and towards the throttle washer 3 with nozzle 5.

The ejection-type liquid flow divider for the nozzle operates as follows.

At the beginning of the formation of the torch, the sprayed liquid stream has the highest speed, and when it enters the generating grid, foam is formed with small air bubbles (2 ÷ 3 mm across), due to air ejection through the grids 8, 9, 10 of the divider 7, and with removal from jet 5, the jet velocity drops and then foam forms with larger bubbles (4 ÷ 12 mm across) of air on the mesh. Thus, the divider produces polydisperse (differently sized for bubbles) foam, which has the property of rapid spreading over the surface. Obtaining foam is carried out according to the principle of ejection of air by sprayed jets of liquid in the divider 7.

The proposed nozzle divider design can be used as a finely dispersed sprayer in fire fighting equipment, for example, as part of sprinkler or deluge fire extinguishing systems, in agriculture - for spraying various types of substances on sown areas and in industrial premises, as well as in chemical technology devices and in the power system - for spraying fuel, as well as in industries where the generation of atomized finely dispersed fluid flows is required both in closed and open anstve.
