Description

Technical Field

[0001] The utility model provides a pressure regulating valve, belongs to the technical field of coating equipment, and particularly relates to a novel coating pressure regulating valve. Background Art

[0002] Paint is a material that can be applied to the surface of an object to form a solid coating with protective, decorative or other special functions. Its main components include film-forming substances, pigments, fillers, solvents and additives. Paint can form a protective film on the surface of an object to prevent the object from being eroded by environmental factors such as water, air, chemicals, ultraviolet rays, etc., thereby extending the service life of the object. Paint can provide objects with various colors and glosses, giving them beautiful appearances and meeting people's aesthetic needs. Some paints have specific functions, such as fire prevention, anti-corrosion, waterproofing, insulation, antibacterial, etc., and can play a special protective role in specific environments.

[0003] Paint is usually applied manually or by spraying with a spray gun. Spraying with a spray gun is more convenient and greatly saves manpower and material resources. However, if the pressure in the delivery pipe is insufficient, the spray pressure may be unstable, thus affecting the uniformity and quality of the coating. In addition, too high a pressure may damage the spray gun and equipment, while too low a pressure may cause the paint to fail to atomize effectively, affecting the spraying effect.
