SU665947A1 - Nozzle for producing fan-shaped jets - Google Patents

Description

-; I

The invention relates to the field of washing nets, shafts and other paper-making and board-making machines and can be used in the paper industry, as well as in other industries: in cooling towers, in agriculture for sprinkling and processing of plants with chemicals, in the building industry. for spraying paints and solutions, watering streets, etc.

Known nozzles for obtaining see-through jets include a housing with a placed & It has a spring loaded piston with a central channel and a reflector of a complex configuration ij.

A fan-shaped jet is formed in the gap between the piston and the reflector,

However, such attachments do not provide stable operation,

The closest to the invention in its technical essence and the achieved result is the nozzle of receiving fan-shaped jets containing

housing with a nozzle and mounted on the housing head with a reflector at its end 2,:. .

The disadvantage of it is that it does not always ensure obtaining the required thickness and angle of the fan, does not allow to accurately reproduce the parameters of the fan-shaped jet in the manufacture of the new nozzle instead of the worn out one and adjust the thickness of the jet without replacing the nozzle.

The aim of the invention is to provide the possibility of adjusting the angle of divergence and the thickness of the jet and to simplify the design of the device.

This goal is achieved by the fact that in the pre, lagging nozzle, the end of the bent hole is made as part of a cut cylinder, and the reflector is in the form of a plate facing the working surface to the nozzle, the head being mounted on the body with the possibility of axial movement. In addition, the ratio of the distance from the lower edges of the cut-off part of the cylinder to its inner diameter to the diameter of the body is 0.35-0.712. FIG. 1 shows a general view of the top; in fig. 2 - side view; in fig. 3 is a section along A-A in FIG. 1, the nozzles for receiving fan-shaped jets comprise a housing 1 with a nozzle 2 and a head 3 mounted on the housing 1 with a reflector 4 at its end. . The housing 1 is screwed into the shower pipe 5 and secured with a nut 6. The end-heads 3 are made as part of a cut cylinder, and the reflector 4 is in the form of a semicircular flat plate with a diameter B (2 - 3) d, where d is the diameter of the barrel 1. The head 3 is mounted on the housing 1 with the possibility of axial movement. A locking screw 7 is mounted on the head 3, fixing the position of the head 3 and the reflector 4 fixed to it relative to the end of the body 1, in order to obtain a fan-shaped jet of the required thickness “c. , --- -. On the inner cylindrical surface of the head 3 there are four labyrinth seal grooves. A fan-shaped jet is formed in the gap between the protruding end of the housing 1, the reflector 4 and two lateral horizontal planes formed as a result of cutting off a part of the cylindrical surface of the head 3. The stream comes out of the nozzle perpendicular to the axis of the housing 1, and the angle of divergence of the jet fan depends on sizes E and d, where E is the depth of the remaining part of the cut on the head 3, the outer diameter of the housing 1. So with respect to eO, 712, OL в90 °, with I аО, 462. (А 15О ° and at j: tO, 35 "X 180 °. From these data the required depth of cut B is determined, in order to provide the necessary angle of divergence of the fan, also with the known diameter d of the body, 1..... .-. - .., - - - The change in the gap between the end face of the housing 1 and the reflector 4 is adjusted

Claims (2)

665947 the tolgcine of the jet is needed, followed by fixing the hapovka 3 and the reflector 4 fixed to it on the housing 1 with the help of the locking screw 7. The proposed nozzle for allowing fan-shaped jets has the following advantages compared to the existing nozzles: ease of manufacture of the nozzle; ability of fan-shaped struit thickness and divergence angle of the fan, possibility of obtaining fan divergence angle by selecting the ratio CG V .. stability of obtaining the required parameters of fan-shaped jets: thickens the jet and the angle of divergence of the fan when the new nozzle is made instead of worn out. Claim 1. A nozzle for producing fan-shaped jets comprising a housing with a nozzle. and a head mounted on the housing with a reflector at its end, which is designed so that, in order to ensure the possibility of adjusting the divergence angle and jet thickness and simplifying the design, the end; the heads are made as part of a cut cylinder, and the reflector is in the form of a plate facing the working surface to the nozzle, with i the head mounted on the body with the possibility of axial movement. 2. The nozzles of claim 1 are also distinguished by the fact that the ratio of the distance from the lower edges of the cut part of the cylinder to its internal diameter to the diameter of the body is 0.35. 0.712.
