. "

The invention relates to a device for spraying liquids and can be used for spraying and applying paints and varnishes,

A sprayer of paints and varnishes is known, comprising a detachable body, a spray plate fixed to the body with a conical shaped outlet in communication with a paint supply channel, and with two additional conical shaped holes in communication with a compressed air supply.

A disadvantage of the known device is the insufficiently high reliability and quality of the resulting coating using high viscosity paints and varnishes.

The aim of the invention is to increase the reliability of the work and improve the quality of the coating.

This goal is achieved by the fact that in the sprayer of paints and varnishes containing a detachable body, a spray plate fixed to the housing with a conical shaped outlet in communication with a paint supply channel and with two additional conical shaped holes in communication with the compressed air supply and a vibrator , the vibrator is made in the form of a spring-loaded ball-valve located at the outlet of the paint supply channel in the area of the outlet of the spray plate.

In FIG. 1 shows a spray booth; in FIG. 2 - spray, section; in FIG. 3 is a section AA in FIG. 2; in FIG. 4 is a section bB in FIG. 2.

The painting apparatus contains a pressure tank 1 with a loading neck and a spray 2.

The tank 1 is connected by a hose 3 to the compressed air supply system and valves 4, 5 are connected to the spray gun 2. The spray gun 2 is equipped with 7.8 valves for supplying compressed air and paint, respectively.

The sprayer 2 comprises a detachable body 9 and a spray plate 10. The spray plate is fixed to the body 9 by means of a cover 11, a frame 12 and a wing bolt 13.

A sealing gasket 14 is installed in the housing 9. The spray plate 10 is made with a conical shaped outlet 15 in communication with the paint supply channel 16 and with two additional conical shaped holes 17 in communication with the compressed air supply channels 18 and located on both sides from a convex hole at a converging acute angle. At the exit of the paint supply channel 16, a vibrator is arranged in the form of a spring-loaded ball-valve 19 in the area of the conical hole 15.

Between the holes 15 and 17, grooves 20 communicating them are made.

The painting apparatus works as follows.

Tank 1 is filled with paint and varnish material and connected to a compressed air supply system. „-,

Under the pressure of compressed air, the paint material from the tank 1 is fed through a hose 5 to a valve 8 with a spray gun 2.

From the upper part of the cavity of the tank 1, compressed air is supplied through a hose 4 to the valve 7 of the spray gun 2. When the valve 8 is opened, the paint material enters the channel 16 and the outlet 15 of the spray plate 10. When the valve 7 is opened, the compressed air enters the channels 18 and then leaves atmosphere through additional openings 17. Exiting from openings

15, the paintwork material is sprayed with two jets of compressed air and deposited on the surface to be treated,

In the process of spraying paint and varnish material, the spring-loaded ball-valve 19 is in constant oscillatory motion and creates a vibration of the flow of paint and varnish, which increases the dispersion of its spray.

The presence of grooves 20 between the holes 15 and 17 also contributes to an increase in the dispersion of the spray paint and uniformity of the resulting coating.

When the supply of compressed air to the tank 1 is stopped, the pressure of the paint material in the channel 16 decreases and the ball-valve 19 closes the outlet 15, which prevents the outflow of paint and increases the reliability of the sprayer.

Claims (1)

The claims Sprayer of paints and varnishes, comprising a detachable body, a spray plate fixed to it with a conical-shaped outlet in communication with a paint supply channel and two additional conical-shaped holes in communication with a compressed air supply, and a vibrator, characterized in that, for the purpose of To increase operational reliability and improve the quality of the coating, the vibrator is made in the form of a spring-loaded ball valve. placed in the area of the outlet of the spray plate. 3 / J-- air Puz.j SO eleven 76 eighteen Editor O.
