(57) Abstract:The invention relates to a device for spraying (spray) gas, liquid and powdered products and can be used in various fields of economic activity. The atomizer is a disk enclosure with cast nozzle half of its diameter with two symmetrical sectoral dampers on one quarter of its circumference. Rotate pie dampers allows you to adjust the length of the slot nozzle from zero to half of the diameter of the casing and provides a spray angle of the product from 0 - 180o. The technical result of the invention is to enable adjustment of the angle and width of the spray in a small gap spaces. 3 Il. The invention relates to a device for spraying (spray) gas, liquid, gas-liquid and powdered funds and can be used in burners and nozzles of various combustion devices, paint sprayers, hydromechanik machines, dyes, subsurface distribution media under tillage in agriculture, etc.Known spray containing cylindrical body, which is made radially-slotted nozzle (patent is I spray angle.Known dispenser containing a hemispherical body and a valve with radially-slotted nozzles (U.S. patent N 2544933, class B 05 B 1/30, 1953).A disadvantage of the known atomizer is a control spray angle around the circumference, and the impossibility of using it in a small slot spaces, in particular, in the interests of the applicant, under pokorivshij paws agricultural tools for subsurface tillage.The prototype of the invention may be recognized as a dispenser, comprising a housing and a flat nozzle with tube feeding spray (USSR author's certificate N 528950, class B 05 B 1/30, 1977).The disadvantage of the atomizer is the inability to adjust spray angle and applying it in the small slot spaces.The proposed atomizer allows you to obtain a new technical effect of the adjustment of the angle and width of the spray in a small gap spaces.This technical effect is achieved by the fact that the body is made in the form of a disc (washer), and cast the nozzle in the form of radial slits in the plane of the disk to one-half of its diameter, in this case by his form has two symmetric sector, one quarter Okruzhnoye.In Fig. 2 - view of Fig.1 by the arrow A.In Fig. 3 is a cross - section of Fig. 1 along a-A.The sprayer consists of a disc (washer) of the housing 1, which in its plane to one-half the diameter of a radial jet slit 2 with a cylindrical bore 3 opposite from the nozzle 4. Along the axis of the body 1 has a through hole 5 with the axial bolt 6. In an integral part of the housing 1 above to allow the slit 2 is made of two symmetrical through holes 7. The housing 1 by its shape with two symmetrical about one quarter of its circumference, sector flaps 8, movably mounted on the axial bolt 6.The spray works as follows. Loosen the nut axially of the bolt 6, turn it flaps 8 and symmetrically overlap with both sides of the nozzle slit 2 buildings 1. Set the angle and width of the spray pattern. The nut of the bolt 6 is tightened and fixed to the specified position of the vanes 8. Through holes 7 of the bolt body 1 is fixed in position, for example under pastoriusa paw agricultural implements in the direction to allow the slit 2 on the sector sweep legs (not shown). The fitting 4 with excess pressure in the nozzle slit 2 apply the product to be processed, which RASplus 1 and adjustment of the angle and width of the spray valves 8 may be performed in reverse order.Thus, due to the small size of the disk body 1 in the form of washers it is possible to install small gap spaces, like under the paw of agricultural implements, and due to the adjustment of the sector to allow the slit 2 and the adjustment of the spray angle possible to set the width of the spray pattern width of capture of this paws. Spray containing cylindrical body and a flat nozzle with the inlet connection of the atomizer, wherein the body is made in the form of a disk, and cast the nozzle in the form of radial slits in the plane of the disk to one-half of its diameter, in this case, according to its form, has two symmetric sector, one quarter of the circumference of the body, each of the flaps can be rotated on its axis.
FIELD: oil and gas industry.
SUBSTANCE: in end piece, flow conic slit-like channel of variable section is made screwed with rotation of longitudinal axis for angle 20-60°. Section at output is decreased in comparison to input in 1.5-3 times.
EFFECT: higher efficiency.
