Abstract
The utility model relates to a spray gun for the inner wall of a long narrow tube. A negative-pressure cavity body is screwed on a high-pressure air nozzle, the right end of the negative-pressure cavity body is fixed with a paint discharge pipe which is of the same shaft center with the high-pressure air nozzle, and a cylindrical hole is arranged in the negative-pressure cavity body and is communicated with the paint discharge pipe through a conical transition hole. A paint suction mouth is communicated below the cylindrical hole, the front end head of the high-pressure air nozzle exceeds the paint suction mouth, and an annular negative-pressure cavity is formed between the outer wall of the high-pressure air nozzle and the inner wall of the cylindrical hole in the negative-pressure cavity body. The utility model has the advantages of simple structure and convenient operation, makes sprayed paint form mist-shaped beam flow and have certain pressure, and successfully solves the problem of the inner wall spray of a long narrow tube. The spray gun can be used for spraying the long narrow tube within one meter, and can also be used for washing an inner hole of the long narrow tube.
Description
The utility model relates to a kind of elongated tubular inwall spray gun.
The spray gun that uses adopts the high pressure valve that pressure-vaccum lacquer mouth is produced negative pressure now, make the paint of ejection when the hurried expansion of gas, the principle of the atomization of liquid be made, be the large tracts of land divergent shape during paint (or other liquid coating) ejection, the suitable outer surface spraying that is easy to large tracts of land or complex object, for tube wall, particularly the tube wall of slim pipe diameter then can't spray into, and the materials of widely applying in the industrial production such as steel pipe, owing to reasons such as easy corrosion in use need be carried out coated to inwall, penetrate pipe as the whip antenna width of cloth of producing in the electron trade, make by caliber φ 3.5～φ 12 steel pipes, because inwall can't be handled, the steel pipe corrosion takes place in the use, influence serviceability, reduced service life, become a difficult problem anxious to be solved in the production, in the domestic and external like product, internal surface of elongated tube is handled does not all have desirable processing method.
The purpose of this utility model is to design a kind of specific purpose tool elongated tubular inwall spray gun that can solve an elongated tubular inner-wall spraying difficult problem.
Design of the present utility model: a kind of elongated tubular inwall spray gun, comprise rifle body (1), high-pressure jet mouth (2), inhale lacquer mouth (4), lacquer chamber (5), handle (6), pressing plate (7), air valve (8) and joint (9), inhaling lacquer mouth (4) is contained on the suction lacquer pipe (10) that coats with lacquer chamber (5), lacquer chamber (5) spinning is in rifle body (1) front end below, handle (6) be positioned at rifle body (1) rear end the below and with rifle body (1) be an integral body, the rear end of rifle body (1) is hinged with pressing plate (7), air valve (8) and joint (9) are housed, being shaped on high pressure air flue (11) in addition in the rifle body (1) joins with the high-pressure jet mouth (2) that is fixed on rifle body (1) end, be installed with vacuum cavity (13) on the high-pressure jet mouth (2), the right-hand member of vacuum cavity (13) is fixed with the lacquer that goes out of high-pressure jet mouth (2) concentric and manages (3), be shaped in the vacuum cavity (13) greater than the cylindrical hole (12) that goes out lacquer pipe (3) internal diameter, cylindrical hole (12) right-hand member by tapering transition hole (14) with go out lacquer pipe (3) and communicate, the below of cylindrical hole (12) communicates with suction lacquer mouth (4), and the front end of high-pressure jet mouth (2) surmounts inhales lacquer mouth (4), formation ring-type negative pressure cavity (15) between the inwall of the cylindrical hole (12) in the outer wall that makes high-pressure jet mouth (2) and the vacuum cavity (13).
Operation principle of the present utility model:
Utilize the jet-action of pressure-air, the negative pressure that when pressure-air enters out the lacquer pipe through air nozzle, flows and produce rapidly, at the high-pressure jet mouth and go out to coat with lacquer between the pipe negative pressure cavity of design, negative pressure cavity links to each other with the lacquer chamber by inhaling Qi Zui, utilize negative pressure that (or other liquid coating) sucking-off is painted in the chamber of lacquer, inject out the lacquer pipe through negative pressure cavity, because liquid sucks out the gases at high pressure atomizing that the lacquer pipe is flowed rapidly through the annular gap, when going out the ejection of lacquer pipe, form vaporific line, realize spraying tube wall owing to go out to coat with lacquer tiing up of pipe.
The utlity model has following advantage and effect:
1, because the lacquer (or other liquid coating) of this spray gun ejection is vaporific line, and the spray atomizing effect is good, line is long, and has certain pressure, has successfully solved the difficult problem of elongated tubular inner-wall spraying, can spray 1 meter with interior elongated tubular, and outer surface is had no effect.
2, simple in structure, easy to operate, the efficient height, paint film is even, except that compressed air, need not special auxiliary equipment, not limited by operation field, and is very practical.
3, because the spray of this lance ejection has certain pressure, except that being used for spraying, also can be used for the cleaning of elongated tubular endoporus.
4, this spray gun is tried out in the electronic product whip antenna width of cloth and is penetrated the inner surface of pipe and spray paint, this antenna length of tube 365mm, and totally seven kinds of maximum caliber φ 9, minimum pipe φ 3.5, it is good evenly to cover through the surperficial paint film of spraying, and the working (machining) efficiency height is about to be used for produce in batches.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is an A portion enlarged drawing among Fig. 1.
1,2 embodiment of the present utility model is described in conjunction with the accompanying drawings.
