Spray

 

(57) Abstract:

The atomizer is a hemispherical body, which is made of cast coplowe device, and the scope is equipped with an adjustable damper, which made two diametrically spaced cut two arcs with endpoints on the axis of rotation to change the spray angle from 0oto the maximum. When you turn the throttle it cuts provide for changing the spray angle from 0 to 180oi.e. any width slot nozzle of the torch. The technical result of the invention is the possibility of obtaining an adjustable angle flat spray and two-way spray pattern with uniform distribution of the sprayed substance. 2 Il.

The invention relates to a device for spraying (spray) gas, liquid, liquid-gas and dust environments 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. Such nozzles do not provide the setting in which ipom invention is an atomizer, containing a hemispherical body and a movable louver damper, having a radially-slotted nozzle. This spray also does not provide adjustment of the spray angle (U.S. patent N 2544933, class B 05 B 1/30, 1951).

Also known dispenser containing a hemispherical housing and louver damper, having a radially-slotted nozzle (USSR author's certificate N 528950, class B 05 B 1/30, 1977).

The disadvantage of the prototype is that the adjustment of the spray angle is provided on the cone, which eliminates the possibility of its application in terms of tape processing, for example soil in agriculture, where cast (and not circular) process in motion, because the circular dispersion in the movement does not provide the uniformity of distribution. This is because the movement on the sides of the circle are made in two times less than the sprayed substance, and along an axis of motion - twice, because the pass front and rear part of the circle. In the condition of agriculture sprayers are installed under agricultural implements, as an opener and subsurface cultivator. where the height of the soil surface is very small, and the width of the processing variable within wide limits. So you want planar nozzles shall sabreena allows you to obtain a new technical effect of an adjustable angle flat spray and two-way spray pattern with uniform distribution of the sprayed substance.

This technical effect is achieved in that on the housing radially-slotted nozzle is made in the same diametrical plane, and the flap is in the form of two diametrically spaced notches between two identical arcs with endpoints on the axis of rotation to ensure that changes the spray angle from 0 degrees to maximum.

In Fig. 1 shows a General view of the dispenser with allow the parties.

In Fig. 2 is a cross - section of Fig. 1 along a-A.

The sprayer consists of a hemispherical casing 1, made of solid material, which in one diametrical plane made two radially-slotted nozzle 2 jumper 3 between them. In the housing 1 from the reverse side of its hemispherical surface on the axis and its shape is made hemispherical distribution chamber 4 with the cover 5 and product nozzles 6. The housing 1 on its hemispherical surface provided with a valve 7, in which the two diametrically spaced cutout 8, each between two arcs 9 and 10 with the ends on the axis of the rotation.

The flap 7 is provided with an annular rams 11 and the housing 1 to the mounting bracket 12. Valve 7 is fixed to the body 1 along its axis by a bolt 13 in threaded connection with jumper 3 of the housing 1. When this flap 7 operate as follows. Bracket 12 case 1 atomizer is fixed, for example, under the agricultural pastoriusa paw. Through the product outlet 6 into the hemispherical chamber 4 under pressure is fed a liquid medium which is divided diametrically spaced radially-slotted nozzles 2 and through the notch 8 arcs between 9 and 10 in the valve 7 radially in the form of a sector of a semicircle is thrown on the soil (down). In this case the maximum cutting width at the maximum angle of spray is about 180 degrees. Depending on the width and height of the gun, which has a sprayer, adjust the angle of spray. To do this, loosen the bolt 13 and, turning lamb 11 counterclockwise (as shown in the drawing), turn the valve 7, while the arc 10 of the recess 8 of the valve 7 begin to overlap pereferiynye the ends of the radially-slotted nozzles 2. So as you turn the valve 7 is diametrically narrowing cast spray liquid medium, i.e., the decrease of the angle of the spray to the desired width agricultural implements, in particular pastoriusa paws up to zero. Set the spray angle is fixed by fastening flaps 7 bolt 13. When turning the valve 7 in the mod is OTE valve 7 begin to overlap arcs 9 cut 8 from the axis of rotation, i.e. the middle to the periphery when the full width of the spray pattern in the form of two strips of the desired width.

When turning the parts of the valve 7 counter arcs 10 and 9 to each other in the cut-outs 8 regulate as spray angle, and the width of the strips.

Dispenser containing a hemispherical body and form a movable louver damper, having a radially-slotted nozzle, characterized in that on the housing radially-slotted nozzle is made in the same diametrical plane, and the flap is in the form of two diametrically spaced notches between the two arcs with endpoints on the axis of rotation to change the spray angle from 0oto the maximum.
