SU1547852A2 - Sprayer for heat moisture treatment of air - Google Patents

Abstract

The invention relates to an air-conditioning technique and can be used in sprays for heat and humidity treatment of air. The goal is to increase the efficiency of the sprayer by making it possible to control the dispersity of the sprayed liquid. For this purpose, in the spray gun for heat and air humidity treatment, the diameter of the wire section of the additional spring is different from the diameter of the wire section of the main spring. Additional spring is installed with the possibility of removal and replacement. To increase the reliability and durability of the sprayer operation, the main and additional springs are made of rectangular wire. The spring wire section profile can also be made in the form of segments facing the base of each other. The use of springs made of profiled wire allows for more effective self-cleaning of springs from salt deposits during the process of switching the spray gun on and off, as well as during pressure pulsation in the spray liquid supply system during the spray gun operation. 3 hp f-ly, 5 ill.

Description

The invention relates to an air-conditioning technique, can be used in sprays for heat and moisture treatment of air and is an improvement of the known spray gun according to the authors. St. No. 1156744.

The purpose of the invention is to increase the efficiency of the sprayer by allowing control of the dispersion of the sprayed liquid and increasing the reliability and durability of the sprayer.

FIG. 1 shows schematically the structure of a sprayer; in fig. 2 is a view A of FIG. 1 (installation of additional and main springs); in fig. 3 shows the node I in FIG. 1 (installation of the second additional spring); in fig. 4 and 5 - spring sections in

when using profiled wire.

The spray for heat and air treatment contains a manifold 1, installed at the outlet of it the main spring 2 with threads adjacent to each other and the plug 3 at the free end and an additional spring 4, made similarly and installed axially with the main spring 2, and the direction of the turns the spring 4 is opposite to the direction of the turns of the main spring 2, the inner diameter of one spring is equal to the outer diameter of the other, and the diameter of the wire section of the additional spring 4 is different from the diameter with Wire springs of the main spring 2.

An additional spring 4 is fixed to the collector 1 and the plug 3 by means of threaded bushings 5 and 6. Springs 2 and 4 can be made of rectangular wire (Fig. 3) and in the form of segments that are turned to each other with the bases (Fig. 4 ). Additional springs 4 may be several, and the direction of winding of each subsequent spring must be opposite to the direction of the previous winding. To install the second additional spring 7, there is a sleeve 8, which is threaded on sleeves 5 and 6. To install the spring 7, protective caps 9 and 10 can be used, in addition, sleeve 11 can be used to reduce the size of the caps 9 and 10.

The spray works as follows.

The sprayed liquid flows through a hole in the manifold 1 to the inside of the main spring 2. At a given pressure of the sprayed liquid, the turns of the main 2 and additional 4 springs diverge and form a large number of cells, which are obtained by intersecting the turns of the springs with different winding directions (Fig. 2). Through these cells, the liquid in the form of jets is sprayed into the surrounding space.

To change the stiffness, you need to remove the protective caps 9 and 10 and replace the additional spring 4 with another additional spring with the corresponding stiffness, or insert a second additional spring 7 with protective caps 9 and 10 of the appropriate size (Fig. 3). This adjustment is made

with minimal time without disassembling the main spring 2.

The use of springs made of profiled wire will heal the more efficient self-cleaning of springs from salt deposits during the on and off - sprayer, as well as during pressure pulsation in the sprayed supply system during the sprayer operation.

To increase the dispersion of the spray (increase the number of jets of sprayed liquid), the additional spring 1 is made of wire of a smaller diameter than the main spring 2.
