Abstract
The utility model relates to a high viscosity paint gun. A distributing valve is arranged in a spray head body; an upper air passage, a lower air passage and a paint feeding passage are arranged on the distributing valve; a net group and a spray head cavity are arranged between the distribution valve and the spray head; the upper air passage is provided with a regulating valve. Having the advantages of simple structure, flexible use and convenient use, the utility model has a high atomizing ability under the same work (air pressure) condition, and can directly spray high viscosity paint. The utility model can save great amount of solvent, can reduce cost, can lighten environmental hazard from the solvent volatilization and can improve labor condition; coating layers can not be easy to flow and the utility model can spray thickness once, so the utility model can enhance work efficiency; having the advantages of high paint mist density, the utility model can lighten that the moisture in air influences paint film quality and can enhance the adhesion quality and the surface quality of the paint film.
Description
The utility model relates to spray gun, more particularly is the high viscosity paint airbrush.
Present air atomization spray gun is under the gases at high pressure effect of 0.4MPa, the high viscosity lacquer is fully diluted afterwards (about viscosity 30S---coating-4 viscosity meter), spray to working face, the condition of this spray gun is to use the Macrodilution agent with the dilution of high viscosity lacquer, need spray multipass during the spraying thick coating, work efficiency is low, cost is high, contaminated environment is serious, and because the good paint film diluent of spraying is by surface progressively volatilization inwards, and what influence paint film adheres to quality and surface quality.
The purpose of this utility model can be eliminated above-mentioned shortcoming in order to provide a kind of exactly, can directly spray the high viscosity paint airbrush of high viscosity lacquer.
In order to achieve the above object, this device is provided with distributing valve (4) in sprayer body (3), distributing valve is provided with air flue (6), downtake (14) and supplies lacquer passage (11), is provided with net sheet group (10) and shower nozzle cavity (7) between distributing valve and shower nozzle (9), and last air flue is provided with control valve (15).
The last air flue (6) of this device distributing valve (4) connects shower nozzle cavity (7) by control valve (5), and downtake (14) connects compound storage tank (13), and net sheet group (10) is to be formed by stacking by many external diameters fine-structure mesh sheet identical with shower nozzle (9) internal diameter.
The utility model is simple in structure, flexible and convenient to use, applied widely, under the identical situation of condition of work (air pressure), has very high atomizing ability, can directly spray the high viscosity lacquer, not only save a large amount of solvents, reduce cost, alleviate the harm of solvent evaporates to environment, improve working conditions, and because coating is difficult for trickling, can disposable spray thick, can improve work efficiency greatly, and because coating cloud concentration is higher, can alleviate the influence of airborne moisture to painting quality, that can improve paint film adheres to quality and surface quality.
Be described further below in conjunction with accompanying drawing:
Description of drawings: figure is the device cutaway view.
This device is provided with distributing valve (4) in sprayer body (3), distributing valve is provided with air flue (6), downtake (14) and supplies lacquer passage (11).
The downtake of this device (14) connects compound storage tank (13), and gases at high pressure enter in the compound storage tank, and under the gases at high pressure effect, the paint in the compound storage tank enters being sprayed by shower nozzle (9) for lacquer passage (11) of distributing valve (4) by transmission pipe (12).The lacquer mode that supplies like this is that pressure is for the lacquer mode.In order to improve the atomizing ability, the utility model is provided with net sheet group (10) between distributing valve and shower nozzle (9), net sheet group is to be formed by stacking by many external diameters fine-structure mesh sheet identical with the shower nozzle internal diameter, also can make a kind of similar trickle mesh-structured integral material that has, there is a centre bore (15) at the center of net sheet group, the spray orifice of centre bore and confession lacquer passage (11), shower nozzle (9) is on same straight line, the diameter of centre bore is littler than the injection diameter of shower nozzle, and lacquer liquid is by entering net sheet group switching centre hole for the lacquer passage and being sprayed by spray nozzle.
The key of this device is to be provided with air flue (6) on distributing valve (4), when gases at high pressure enter compound storage tank by downtake, the part gases at high pressure enter shower nozzle cavity (7) by last air flue, enter the gases at high pressure in the shower nozzle cavity, can enter by the micropore of net sheet group (10) by in the middle of the lacquer stream that flows to net sheet group switching centre hole (15) for lacquer passage (11), and gases at high pressure are when and irregular micropore tiny by net sheet group, be separated into countless strands of superfine little and inconsistent high pressure draughts of flow direction, after entering in the lacquer stream, these air-flows have just become special dispersant, when lacquer stream is gone out shower nozzle, compressed air acutely expands, make the fragmentation of lacquer stream be dispersed into superfine coating cloud particulate, reach the purpose that improves the atomizing ability.
In order to regulate air inflow that enters air flue (6) and the ratio of coating with lacquer liquid, this device is provided with control valve (5) on last air flue, turn control valve and can control the air inflow of air flue, under the certain situation of lacquer fluid viscosity, control valve opening is excessive, and will to use the lacquer amount very few, and coating cloud concentration is little, if control valve opening is too small, air-flow undersupply then, lacquer stream concentration is excessive, influences atomizing effect.
During the work of this device, plug tracheae plug (1) and connect gases at high pressure, pull in the distributing valve (4) that trigger (2) gases at high pressure enter sprayer body (3), and enter air flue (6) and downtake (14) respectively, the gases at high pressure that enter downtake make lacquer liquid coat with lacquer passage (11) along the confession that transmission pipe (12) enters distributing valve, and are sprayed by shower nozzle (9) through net sheet group (10).The gases at high pressure that enter air flue are regulated the tolerance that enters shower nozzle cavity (7) with control valve (5), can carry out work when atomizing effect reaches the best.
This device can be arranged to two spray orifices or many jet orifice structures form.
The utility model is simple in structure, the atomizing ability strong, use no or little diluent, can reduce cost, improve work efficiency, reduce environmental pollution, be the regeneration product of normal air atomizing lance, can be widely used in the spraying application of industries such as auto repair, furniture production, construction and decoration.
