Abstract

The invention relates to a spray technique and can be used in construction for the installation of mastic roofs and waterproofing coatings and the application of finishing compositions. The goal is to improve spray quality. For this, the sprayer is provided with a distributor placed in the outlet section of the feed channel, made in the form of a grid with generators arranged at an acute angle to the axis of the feed channel in the direction of flow of the sprayed material. The forming grids can be made with a rhomboid or ellipsoid cross section. The atomizer provides effective fragmentation and deviation of the jets of the fractured viscous flow from the initial flow direction, which contributes to the formation of a fine aerosol suspension of the sprayed material in the annular flow of the ejecting compressed air in the jet plume after it leaves the atomizer. 2 hp f-ly, 2 ill.

(57) The invention relates to the technique of spraying and can be used in construction for the installation of mastic roofs and waterproofing coatings and the application of finishing compositions. The goal is to improve the quality of brushing. For this purpose, the spray gun is provided with a spreader in the outlet section of the feed channel made in the form of a grid with formers located at an acute angle to the axis of the feed channel in the direction of movement of the flow of the screwed material. The forming grids can be made with a rhomboid or an ellipsis cross-section. . The dispenser provides effective crushing and deflection of the jets of the fractured viscous stream. fluid from the original direction. flow, which contributes to the formation of fine air suspension of the material to be fi ned in the annular flow of the ejecting compressed air in the jet plume after it leaves the sprayer. 2 hp f-ly, 2 ill.

The invention relates to the technique of spraying, can be used in construction for the installation of mastic roofs in waterproofing coatings, as well as for applying finishing compositions and is an improvement of the invention, according to the author. St. No. 741950. I

The purpose of the invention is to improve spray quality.

Figure 1 shows the sprayer, a general view; figure 2 - section aa in figure 1.

The sprayer includes a housing 1, covered by an air cap 2,

in which there is a nozzle mounted on the pipe 4 supplying the sprayed material connected to the fitting 3, made in the form of i of the piston 5 with the inlet channel 6. And the outlet section in the form of a conical socket 7 installed with the possibility of reciprocating movement and equipped a shut-off valve in the form of a ball 8, discharged in the supply channel 6.

The connecting channel 6 is made tapering with a cross-sectional shape other than a circle.

The ripper is also provided with an inlet placed in the outlet section.

eo

the channel 6 with the divider 9, made in the form of a grid with the generators arranged at an acute angle ct to the axis of the supply channel 6 in the direction of flow of the material to be blended.

The grids forming 10 can be made with a rhomboid or ellipsoidal cross section.

The piston 5 and the pipe 4 have threaded grooves under the spring 11. A seal 12 is fixed on the outer surface of the piston 5 in the groove. The compressed spray air is supplied into the cavity of the housing 1; through the fitting 13, the Air head 2 is made with an outlet 14, The fitting 3 is connected to the flexible hose 15, which supplies the material to be sprayed,

The driver works the following way,

In the initial position, the ball 8 under the action of the spring 11 is pressed to the pipeline 4, Channel 6 is closed. To put the atomizer into operation, compressed air is supplied through fitting 13 into the cavity of housing 1. Under the action of compressed air, piston 5 is displaced forward (down), and with it ball 8 displaces, channel 6 is opened, material passes through splitter windows 9, dissected separate streams, and enters the aerated stream of compressed

air and then to the outlet 14 in the air head 2,

When the pressure in the cavity of the housing 1 drops, the piston 5 returns to its initial position under the action of the force of the spring 11, presses the ball 8 to the pipeline 4, stopping the flow of material

Due to the oscillatory movement of the piston carrying the divider 9 and the ball 8, the viscous material is dispensed from the puller.

Claims (1)

1. The driver of the auth. Yev. No. 741950, characterized in that, in order to improve the quality of the distribution and the material, it is provided with a divider placed in the outlet section of the inlet channel, formed in the form of a grid with generators located under the sharp angle to the axis of the inlet channel in the direction of flow unraveled material 2, A thinner according to claim 1, characterized in that the forming grids are made with a rhomboid cross section, 3, The raspipitel in accordance with claim 1, clause 1, and tl, which is due to the fact that the forming grids are made with a zllipse-like cross section. 15 FIG L Compiled by L.
