Embodiment Construction

[0026] The high-pressure airless spray gun without spraying dead angle of the present invention is described in detail below in conjunction with accompanying drawing:

[0027] Such as figure 1 As shown, the high-pressure airless spray gun without spraying dead angle of the present invention includes an assembly consisting of a gun handle 1, a pressure regulating valve 3 and a high-pressure nozzle 4. Among them, high-pressure nozzles are divided into two types: circular nozzles and fan nozzles.

[0028] The high-pressure airless spray gun without spraying dead angle of the present invention also includes a diaphragm pump (omitted and not shown in the figure) driven by a motor. When the spray gun performs spraying operations, the static pressure generated by the diaphragm pump is used as the driving force for paint spraying. Spray paint directly onto the workpiece surface.

[0029] Such as figure 2 As shown, the high-pressure airless spray gun without spraying dead angle of ...

Abstract

The invention discloses a high-pressure airless spray gun without a blind spraying corner. The high-pressure airless spray gun comprises a gun grip and a high-pressure spray nozzle. A pressure-regulating valve is mounted on the high-pressure spray nozzle, an access end of the high-pressure spray nozzle is a connector matched with an exit end of the gun grip, and the exit end of the gun grip is connected with the access end of the high-pressure spray nozzle. The high-pressure airless spray gun further comprises a diaphragm pump driven by a motor. During a spraying operation, the high-pressure airless spray gun sprays coatings directly on the surface of a workpiece to be sprayed and processed by means of taking static pressure generated from the diaphragm pump as driving force to spray the coatings. Due to the fact that compressed air is not taken as the driving force to spray the coatings, rebounding and splashing of the coatings during the spraying process are basically avoided, and coating fog particles sprayed out can smoothly enter corner cracks and edges of the workpiece with less spraying pollution and no dead corner. The high-pressure airless spray gun has the advantage that a sprayed coating is compact, uniform, glossy, high in flatness and the like.

Description

technical field [0001] The invention relates to a high-pressure spray gun for spraying, in particular to a high-pressure airless spray gun without a spray dead angle. Background technique [0002] As a traditional painting equipment, air spray gun is a kind of finishing equipment widely used in painting construction at present. The working principle of the air spray gun is to use the airflow generated by compressed air to deliver the paint to the surface of the workpiece to be sprayed to complete the spraying of the workpiece. When the airflow generated by the compressed air flows through the nozzle hole of the spray gun, a negative pressure is formed inside the spray gun, so that the paint is sucked through the paint suction pipe of the spray gun, and then the compressed air is used as the driving force to pass through the nozzle of the spray gun driven by the compressed air flow Spray in the form of mist onto the surface of the workpiece to be sprayed to form a uniform pa...
