Technical field
The utility model relates to a kind of spray gun for paint, particularly a kind of high flow capacity low-pressure air spray gun for paint.
Background technology
The English of high flow capacity low-pressure aerial spraying is High Volume Low Pressure, be abbreviated as HVLP, be that the environmental protection that Environmental Protection Agency (EPA) is formulated economizes lacquer spraying standard, the a lot of countries in the whole world all adopt this standard, the transmission efficiency of this standard-required spraying equipment or spray gun (promptly painting utilization rate) must be higher than 65%, nozzle place air outlet slit pressure is equal to or less than 10PSI (0.68 crust), just can be referred to as the HVLP spraying equipment.
But present traditional paint airbrush is because its structural design defect is difficult to reach this standard.Existing spray gun for paint mainly includes rifle body and nozzle, and nozzle comprises a nozzle carrier, and nozzle carrier rear end and rifle body link together, and an air-flow cage ring is set in both junctions; Nozzle carrier front end intermediate throughholes is provided with the material nozzle, and nozzle the inside is provided with the pin plug, and pin plug rear end is stretched out material nozzle and nozzle carrier endoporus and linked to each other with paint vehicle outlet on the rifle body; One air current spray nozzle is set on the nozzle carrier front outer, and air current spray nozzle links together by centring ring and nozzle carrier; In described nozzle carrier is provided with, outer two row's passages, wherein outer vent is communicated with through nozzle carrier outline and the formed gap of centring ring endoporus and with outer venthole on the air current spray nozzle, and interior passage is communicated with through air current spray nozzle endoporus and the material formed gap of nozzle outline and with interior venthole on the air current spray nozzle, in use, Compressed Gas is in nozzle carrier, outer vent is come in, and respectively in air current spray nozzle, outer venthole comes out, thereby reach the uniform purpose of the paint spraying that the pin plug is come out, but because the passage on the existing nozzle carrier directly is communicated with venthole on the air current spray nozzle, the centre is not provided with the baffle structure, cause the air pressure of coming out from the air current spray nozzle venthole too high, and air-flow skewness, had a strong impact on the mist width of cloth effect of pin plug ejection paint, the transmission efficiency of spray gun for paint approximately has only about 30% simultaneously, and other about 70% paint spreads in the middle of the surrounding environment along with flying mist, this not only increases cost, and contaminated environment, have a strong impact on constructor's health.
The utility model content
The purpose of this utility model is to provide a kind of high flow capacity low-pressure air spray gun for paint; it is provided with the baffle structure between the venthole of the passage of nozzle carrier and air current spray nozzle; compressed air is flowed out from the venthole of air current spray nozzle uniformly; can greatly reduce and fly mist and bounce-back; reduce paint and solvent discharge amount; save the paint consumption greatly, can keep the clean and tidy of working environment simultaneously, protection atmospheric environment and workmen are healthy.
For achieving the above object, the utility model is by the following technical solutions:
A kind of high flow capacity low-pressure air spray gun for paint, include rifle body and nozzle, described nozzle is by nozzle carrier, the air-flow cage ring, the material nozzle, the pin plug, air current spray nozzle and centring ring are formed, in described nozzle carrier is provided with, outer two row's passages, wherein outer vent is communicated with through nozzle carrier outline and the formed gap of centring ring endoporus and with outer venthole on the air current spray nozzle, and interior passage is communicated with through air current spray nozzle endoporus and the material formed gap of nozzle outline and with interior venthole on the air current spray nozzle, it is characterized in that: between described nozzle carrier outline and the formed gap of centring ring endoporus an outer flow-stopping plate is set, between air current spray nozzle endoporus and the formed gap of material nozzle outline, flow-stopping plate in is set also simultaneously.
Above-mentioned inside and outside flow-stopping plate is independent split design.
Above-mentioned outer flow-stopping plate is set directly at above the outline of nozzle carrier, itself and the one-body molded design of nozzle carrier.
Flow-stopping plate is set directly at above the outline of material nozzle in above-mentioned, itself and the one-body molded design of material nozzle.
Flow-stopping plate is set directly at above the inner hole wall of air current spray nozzle in above-mentioned, itself and the one-body molded design of air current spray nozzle.
The utility model is provided with flow-stopping plate outside between nozzle carrier outline and the formed gap of centring ring endoporus; between air current spray nozzle endoporus and the formed gap of material nozzle outline, flow-stopping plate in is set also simultaneously; in use; when Compressed Gas when the nozzle carrier passage comes out; at first impact on flow-stopping plate; enter the venthole of air current spray nozzle subsequently again from the slit between flow-stopping plate and the gap, place; thereby compressed-air actuated pressure is reduced and outflow uniformly; the mist of ejection paint is effective; can greatly reduce and fly mist and bounce-back; reduce paint and solvent discharge amount; save the paint consumption greatly; can keep simultaneously the clean and tidy of working environment, protection atmospheric environment and workmen are healthy.
According to actual processing technology requirement, the inside and outside flow-stopping plate that adopts in the utility model can be independent split design, also can with the one-body molded design of the accessory in the nozzle, when one-body molded design, outer flow-stopping plate can be set directly on the outer surface of nozzle carrier, and interior flow-stopping plate can be set directly on the outer surface of expecting nozzle or be set directly on the inner hole wall of air current spray nozzle.
