Abstract
This invention relates to a pressure air injection gun, which is characterized by the following: setting air valve and coating valve on same axis; setting one gas path in air channel connected to the pressure tar; the pressure cover and the pressure tar are connected by screw lines means; exerting power on the pressure tar through one gas path and sending coating materials with part of air exhausted from air spray to ensure three times of atomization on the air spray. The spray mouth is set with ring hole to make first atomization and the second atomization hole is the reverse flat hole and protective hole and the third hole is edge hole.
Description
Technical field:
The present invention relates to the air gun that a kind of field of coating is used.
Background technology:
At present, air gun is the formula of sucting basically, and the axis of its nozzle body import and the axis of outlet intersect in obtuse angle, promptly when swiftly flowing compressed air flows to air nozzle, form vacuum flow at the coating front end, with the coating sucking-off in the jar, because compressed air must arrive greatly to a certain degree, therefore, it is big to splash during this spray gun spraying, and utilization rate only is 20%-25%, serious environment pollution, and coating repeatedly can not be atomized, cause spraying inhomogeneous, quality is not attractive in appearance.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of utilization efficiency of coatings that improves aerial spraying, reduces environmental pollution, and coating is repeatedly atomized, and improves the pressure sending type air gun of its coating quality.
Technical scheme of the present invention is: air valve and paint valve are arranged on the same axis, being provided with a gas circuit in the air duct communicates with pressurized tank, pressure cover is connected with the screw-type that is connected to of pressurized tank, apply power force feed coating by this gas circuit to pressurized tank, portion of air penetrates from air nozzle, and air nozzle can guarantee that coating carries out three atomizings.The jet hole center is provided with ring-like hole coating is atomized for the first time; orifice is oppositely to flatten hole and protection hole for the second time, and orifice is lateral opening for the third time, and the coating cloud fan governor runs through air duct; be made of slide core, O-ring seals and a holder, lateral opening throughput size is regulated in the slide core turnover.
The present invention will be originally be used as power to inhale with negative pressure and penetrates coating and change into and directly exerting pressure; technology is simple; by the looping pit of this spray gun, oppositely flatten the hole, lateral opening and the protection hole coating is repeatedly atomized; thereby the utilization rate and the coating quality of coating have been improved; reduced the pollution of environment; the coating cloud fan governor is simple in structure, can obtain the coating cloud of broad, and coating is difficult for producing sagging.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view of air duct;
Fig. 3 is the air nozzle front view;
Fig. 4 is the air nozzle vertical view.
The specific embodiment:
With reference to accompanying drawing, air valve 5 and paint valve 3 are arranged on the same axis, being provided with a gas circuit 7 in the air duct communicates with pressurized tank 6, pressure cover is connected with the screw-type that is connected to of pressurized tank, apply power force feed coating by this gas circuit to pressurized tank, portion of air penetrates from air nozzle 1, and air nozzle can guarantee that coating carries out three atomizings.Jet hole center is provided with ring-like hole 10 coating is atomized for the first time; orifice is oppositely to flatten hole 11 and protection hole 9 for the second time; orifice is lateral opening for the third time; coating cloud fan governor 4 runs through air duct; constitute by slide core, O-ring seals and a holder; lateral opening 8 throughput sizes, the 2nd, paint spray nozzle are regulated in the slide core turnover.
