Abstract

The utility model relates to a booster spray gun, which comprises a spray gun, an air outlet pipe, an air inlet pipe, a paint suction pipe, an air compressor and a paint barrel. The utility model is characterized in that the paint barrel is arranged in a sealing barrel body; a suction pipe, a pressure gauge, a safety valve and a three-way valve are arranged on a barrel cover of the barrel body; the suction pipe is inserted on the inner bottom of a suction pipe; the pressure gauge, the safety valve and the three-way valve are communicated with an inner cavity of the barrel body which is hermetically connected with the barrel cover through a bolt; the air inlet pipe is connected with one way of the three-way valve, and the air outlet pipe is connected with one way of the three-way valve; the paint suction pipe is hermetically connected with the suction pipe. The utility model is a spray painting device.

Description

The booster-type spray gun

The utility model relates to ground booster-type spray gun, belongs to the spraying technique field, is a kind of injection apparatus that body surface is sprayed specifically.

The existing spray gun that sprays paint is to provide source of the gas by air compressor, the paint tube that on spray gun, connects a 2kg by tube connector, the disadvantage one that exists is an inefficiency, the 2nd, labour intensity is big, and the 3rd, can not multi-facetedly spray paint, the 4th, the paint tube capacity is little, cause gas pressure undesired, the paint cloudy surface of ejection is inhomogeneous, and the body surface of spraying does not reach light, cunning, bright requirement, and waste paint.

The purpose of this utility model is intended to improve above-mentioned deficiency, and a kind of high efficiency is provided, and labour intensity is little, saves paint and can reach more than 30%, can multi-facetedly spray, and can reach a kind of booster-type spray gun of minute surface requirement to the face of spraying paint.

In order to achieve the above object, the utility model is on the basis of existing technology, realize by improvement, it has spray gun 1, escape pipe 2, inhale lacquer pipe 3, air inlet pipe 10, air compressor machine 11, paint tube 13, be characterized in that paint tube 13 places in the cylindrical shell 12 of a sealing, on the cover on the cylindrical shell 12 15, establish a suction pipe 6, Pressure gauge 8, safety valve 7, triple valve 5, suction pipe 6 is inserted in paint tube 13 inner bottom parts, Pressure gauge 8, safety valve 7, triple valve 5 communicates with cylindrical shell 12 inner chambers, cylindrical shell 12 is tightly connected by bolt 4 and cover 15, one logical joining of air inlet pipe 10 and triple valve 5, escape pipe 2 leads to one of triple valve 5 and joins, and suction is coated with lacquer pipe 3 and is tightly connected with suction pipe 6.

The utility model is by the realization of said structure, can increase work efficiency, need not frequently feed, alleviate labor strength, can realize multi-faceted spraying, the pressure in the cylindrical shell is even, lacquer surface light, the cunning, bright of ejection, can save coating more than 30%, transmission efficiency reaches 60%, and this spray gun is present a kind of reasonable spraying equipment.

Accompanying drawing is a structural representation of the present utility model.

The explanation of accompanying drawing drawing: 1 spray gun, 2 escape pipes, 3 inhale lacquer pipe, 4 bolts, 5 triple valves, 6 suction pipes, 7 safety valves, 8 Pressure gauges, 9 handles, 10 air inlet pipe, 11 compressors, 12 cylindrical shells, 13 paint tubes, 14 supports, 15 covers.

In order to understand better and to implement, it is as follows with the accompanying drawing to be that embodiment further specifies below:

Air compressor machine 11 is a prior art, and the gas outlet of air inlet pipe 10 with air compressor machine 11 connected, and the suction lacquer pipe 3, the escape pipe 2 that connect on spray gun 1, the spray gun 1 are prior art, connects by accompanying drawing to get final product; By accompanying drawing requirement processing one cylindrical shell 12, for cylindrical, the cylindrical shell 12 upper ends cover 15 that is tightly connected, bore one on the cover 15 respectively sipper pore, Pressure gauge hole, safe valve opening, threeway valve opening are installed, hole by separately is tightly connected suction pipe 6, Pressure gauge 8, safety valve 7, triple valve 5 respectively, triple valve 5 is to regulate the pressure size and change the source of the gas direction, and paint tube 13 is placed in the cylindrical shell 12, and the paint tube 13 general paint of containing about 20kg that adopt get final product.Suction pipe 6 lower ends are placed paint tube 13 inner bottom parts, cylindrical shell 12 and cover 15 are tightly connected by a bolt 4.

For easy to use, cylindrical shell 12 lower ends can be equipped with the support 14 of a band universal wheel, can establish leader 9 on the support 14.

During use, open cover 15 by bolt 4, the paint tube 13 that mixes up color is placed in the cylindrical shell 12, paint tube 13 is a no cup, suction pipe 6 lower ends are placed paint tube 13 inner bottom parts, with cylindrical shell 12 and cover 15 good seals, air inlet pipe 10 is led to one of triple valve 5 join respectively by bolt 4, one logical joining of one end of escape pipe 2 and triple valve 5, the upper end of inhaling lacquer pipe 3 and suction pipe 6 is tightly connected.Provide source of the gas by compressor 11 then, when reaching certain air pressure, regulate triple valve 5, making Pneumatic pipe cleaner cross triple valve 5 enters in the cylindrical shell 2, enter in the spray tip by escape pipe 2 again, when observing pressure and reach 0.05-0.2MPa by Pressure gauge 8 in the cylindrical shell 12, can open Switch of spray pistol, by suction pipe 6, inhale lacquer pipe 3 and be transported on the spray tip, will coat with lacquer (or coating) by nozzle by the pressure of escape pipe 2 and spray on the working face.

The operation principle of its spray gun is to borrow the compressed air of compressor with pressurization in the sealed cylinder of splendid attire paint (or coating), makes paint vehicle be pressed into nozzle and atomizes; Simultaneously the pressure that produces of the paint vehicle pressure differential that is compressed air equally and produced carries out atomizing second time, and is sprayed on object surface formation finish paint, so far end-of-job.
