(57) The invention relates to a liquid dispensing equipment, can be applied, for example, as an irrigator for gas cleaning apparatuses in the chemical and other industrial sectors, as well as for washing products. The goal is to increase the efficiency of the device when removing products — by creating a uniform long-range conical flare. For this, the involute nozzle is equipped with

plates, the inner surfaces of which are made in the form of open curves, formed by a successive conjugation of 1/4 of the circumferences of the arcs, the radii of which increase by the same amount equal to the radius of the channel outlet opening. The smallest of the arcs of these curves coincide with 1/4 of the arc of the circumference of the outlet. The plates are rigidly fixed to the inserts on each other with a consistent uniform displacement along the arc of the circumference of the outlet channel opening in the direction of the swirling of the liquid jet. The number of overlays is chosen from the ratio n L / L, where n is the number of overlays, L is the circumference of the channel opening, L is the length of the arc of a circle, by the value of which the subsequent overlay is displaced relative to the predecessor. 1 hp f-ly, 3 ill.

for spraying a liquid and can be used, for example, as an irrigator for gas cleaning devices in the chemical and other industries, as well as for products.

The aim of the invention is to quench the jet of fluid. The number of overlays 8 is determined from the ratio L 5 neither n - -, where n is the number of overlays 8; L is the circumference of the hole 4 of the output channel 3; L is the length of the arc of a circle, by the amount of which the efficiency of the device operation and the subsequent pad are shifted relative to the washing of products due to the creation of the present (a) uniform long-range cone plume.

FIG. 1 depicts an involute

Involute nozzle works as follows.

Fluid is supplied to the inlet nozzle, side view; in fig. 2 - section 15 of the cuttings 1 and at the entrance to the chamber 2, screw-A-A in FIG. one; in fig. 3 - the inner surface of the liner and linings, the cross section.

The stream is divided into several streams. One part of the fluid continues to move along the evolvent of the nozzle; in the swirling chamber 6 it acquires

4, a uniform long-range cone-shaped torch is formed, which allows to ensure uniform removal of the processed products.

Claims (2)

The use of the invention will allow creating a more uniform, cone-shaped torch due to the separation of the curves which increase by the same amount equal to the radius o of the outlet 4 of channel 3, and the smallest of arcs a b of the specified curve coincides with 1/4 of the arc of a circle; the swirling orifice 4, and the largest cd of the nik threads, and at the outlet from the orifice is a continuation of the inner side surface of the inlet 1. The input height is 0.3-0.7 of the height of the twist chamber 2. Torsion chamber 2 is provided with overlays 8, the inner surfaces of which are made in the shape of unclosed curves, and Lc is formed in the tightening chamber on separate sequential conjugation 1/4th flows with different radii, part of circular arcs, corresponding to twisting (different resistance but B with d and bb with both the liquid being swirled and the angles oro, IbV, the radii: of which of the growing torch) followed by the same amount, equal to the co-interaction in the channel evolutively responsive to the radii of pla This will lead to the formation of the outlet 4 of channel 3, with the 50 more uniform and long-range of the smallest arcs, and the total irrigation plume, and the curves recorded coincide with 1/4, respectively, to an increase in the efficiency of the circumference of the outlet 4. These involute nozzles at the cover plate 8 are rigidly fixed in the camera of the product with the retention of its heat of twisting 2 on the insert 7 each 55 barites, on the friend with a consistent uniformity. 1. Involute nozzle according to ed. St. №1297922, about tl and ch yu e e g nym offset a  by arc of circle a and aperture 4; The number of overlays 8 is determined from the ratio L 5 to n - -, where n is the amount of liquid. The liquid is fed into the inlet pipe 1 and at the entrance to the chamber 2, twisted The stream is divided into several streams. One part of the fluid continues to move along the evolvent of the nozzle; in the swirling chamber 6 it acquires     h h p / e 3. Another part of the fluid moving along the internal surfaces of the curves. a b c d insert 7 and abed curves, and a b with cover plates 8, also receives a rotational motion and creates 4, a uniform long-range cone-shaped torch is formed, which allows to ensure uniform removal of the processed products. The use of the invention will make it possible to create a more uniform, cone-shaped torch due to separation, the interaction of these swirling flows is found, and at the outlet of the opening in the swirling chamber into separate streams with different swirling radii (different resistance of the swirling liquid and the angles of the irrigation flame) interaction in the channel of the involute nozzle. This will lead to the formation of a more uniform and long-range total irrigation torch, and, accordingly, to an increase in the efficiency of the involute nozzle during the washing of products with the preservation of its dimensions, In order to increase the efficiency of the device when washing products by creating a uniform long-range conical flare, it is equipped with lining installed in the tightening chamber, the inner surfaces of which are made in the form of open curves, 1/4 of the arcs circles whose radii increase by the same amount, equal to the radius of the channel outlet, the smallest of the arcs of these curves coincide with 1/4 of the arc of the circumference of the outlet, rigid LZ227. - - t-1 -1 / | ////////// 7 /.
