(57) Abstract:Usage: for application of different dyes on the substrate by spraying by means of compressed air. The inventive paint sprayer equipped with two cylinder actuator with continuous air channels and a ring. The socket shell is adjacent to an additional cone nozzle. Shell installed with capability between the nozzle and the nozzle of the nozzle by rotation of the actuator through the slotted couple and made cylindrical and perforated. The design of the spray gun is simple in manufacture and in operation, allows for colouring large surfaces by paint spraying compressed air, eliminating the loss of paint on misting, rebound from a painted surface and environmental pollution, especially in ceiling works and when exposed to wind. 5 Il. The proposed spray relates to the production of painting works. The preferred field of application is the application of various dyes on the substrate by spraying by means of compressed air.Known paint sprayer with the enclosing pneumoconiosis (and.with. b 1207504) though and creates a working torch and enclosing pneumococus at the same time, but the presence of an Autonomous regulator compressed air and values tailings pneumoconiosis create great inconvenience and complexity of optimal synchronization of their interaction. This is especially time-consuming when the replacement replaceable nozzle with a larger or smaller diameter of the outlet (due to different dispersion paints). Eventually came the need to create this semi-automatic paint sprayer.The invention consists in the creation of device related structurally and functionally mobile and fixed nozzles previously unknown forms and assignments, passing constructively in the nozzle controls liquid flow channel passes different forms and directions, slotted, threaded and channel relationships and clamps against twisting, two-cylinder disk drive with intercommunicating air channels communicating with nozzles-regulators (cone nozzle, funnel, cone optional attachment) and the movable locking needle.Izobreteniya surfaces by paint spraying compressed air, completely excluding loss of paint on misting, rebound from a painted surface and environmental pollution (especially for ceiling work, and when exposed to wind). The task turned out to be attainable by the application of design twin atomizer in which a working torch concluded in the regulated pneumococus emanating from the circular slit formed by two movable cone nozzles in cooperation with the movable conical nozzle of the working nozzle. Used in production (paint sprayer CO-71 and other) analogues lose on misting and rebound up to 40% of the ink on the print data of their characteristics.The design of the device illustrated in the drawing, where Fig. 1 shows a longitudinal section; Fig.2 is a section along a - a in the area of the spline of Fig. 3 is a section along B-B in the area of the drive control of Fig.4 - section b-b In the zone of maximum cross-section of the tubular nozzle; Fig. 5 - slice helical channel that replaces the screw connection (if necessary).The device consists of a housing 1 with a centrally installed tubular nozzle 2 having a sleeve 3 passes movable shut-off needle 4 with the piston 5 at the end. Tubular nozzle 2 provided with removable from the Assembly and disassembly between the two cylinder disk drive 11 and a conical additional nozzle 12. Two-cylinder drive disk 11 brings a whole body 1 with the shell 7 and is fastened to the housing 1 by the flange 13. The screw 14 is a stopper nozzle 2. The set screws 15 secure the cowling 7 against rotation, interacting with longitudinal channels 16 of the shell 7 at the time of its axial sliding. Wedge-shaped slots 17 of the socket 9 are connected with straight slots 18 additional cone nozzles 12 and serve as retainers from turning. The spring 19 through the piston 5 presses the shut-off needle 4. The screw 20 to regulate the flow shut-off needle 4. Paint and compressed air are fed through tubes (labels).The spray gun is assembled and operates as follows: on the cowling 7 put additional cone nozzle 12 with straight slots 18 to align them with the wedge-shaped slots 17 of the socket 9. The disk drive 11 of the screw ring 10, then the drive ring screw on the shell 7 with rigid fixing ring 10 for additional cone nozzle 12 and the assembled host put aside. Then in the tubular nozzle 2 is screwed a bushing 3, screw removable nozzle 6, insert the shut-off needle 4 with the piston 5 and the collected node connected with the first data collected by the node so that the set screws 15 entered in the longitudinal channels 16 of the shell 7. Collected in the including locking screw 14 and the fixed flange connection 13 with the disk drive 11. After installing the adjusting screw 20 and the Assembly is almost finished.The operation of the spray gun is practically no different from analogues, in addition to what is required to make the necessary adjustment (set at the average position of the stroke of the disk drive in the threaded connections, which can be replaced as needed helical channels, see Fig.5). Incremental control in the process is to rotate the drive disk 11 to the left or to the right side before the appearance (visually) the optimum ratio of the pressure difference of the working torch and pneumoconiosis, will disappear when misting, which is a sign of loss of paint. The spray gun comprising a housing, a centrally mounted tubular nozzle of variable diameter nozzle and bushing for locking the needle, spring through the piston concentrically located in the housing shell with a conical nozzle and the socket and the basic nozzle, characterized in that it is equipped with a two-cylinder actuator with intercommunicating air channels and a ring, with REDRUM shell located adjacent to the secondary nozzle is made conical, and the cowling is installed with the software wasteway couple and made cylindrical and perforated.
