Abstract
The utility model discloses an air brush, including the spray tube, the spray tube is cylindrical elongated tubular, and the pipe shaft is equipped with a plurality of little through -holes, spray tube one end is the confined, and the other end divide into two branch roads, and a branch road is the gas pipeline, is equipped with the gas valve between gas pipeline and the spray tube, and another branch road is combustion -supporting trachea way, is equipped with combustion -supporting pneumatic valve door between combustion -supporting trachea way and the spray tube. The utility model discloses an air brush of long and thin type, spray tube body have a plurality of tiny flame projecting holes, the effectual burning area that has increased, and the even heating is carried out to the die cavity in all flame projecting holes 360 degrees, provides gas and combustion -supporting gas simultaneously, and it is more continuous to burn, and work efficiency improves greatly.
Description
Technical field
The utility model belongs to aluminium casting mold heated apparatus field, is specifically related to a kind of spray gun.
Background technology
In aluminium casting casting cycle, need aluminium casting mould and die preheating, in prior art, usually make electricity consumption bake or gas burning, electric roasted journey is comparatively slow, inefficiency, the nozzle that original gas burns is just as horn mouth, only has a flame flame, because mold cavity is comparatively large, so the non-uniform heat flux time of being heated is longer.
Summary of the invention
For solving the problem, the utility model provides a kind of spray gun, and this lance combustion area is large, is heated evenly, saves time.
The purpose of this utility model realizes in the following manner:
A kind of spray gun, comprise jet pipe, described jet pipe is cylindrical elongate pipe, pipe shaft is provided with some small through hole, and described jet pipe one end is closed, and the other end is divided into two branch roads, one branch road is gas pipeline, be provided with burnt gas valve between gas pipeline and jet pipe, another branch road is combustion-supporting feed channel, is provided with combustion-supporting air valve between combustion-supporting feed channel and jet pipe.
Described jet pipe is connected by threeway and elbow with branch road front end.
Described jet pipe and branch road front end are formed in one.
Described combustion-supporting gas is compressed air.
Relative to prior art, the beneficial effects of the utility model are:
The utility model is by leptosomatic spray gun, and jet pipe body has some tiny fire jetting holes, effectively increases burning area, all fire jetting holes 360 degree carry out homogeneous heating to die cavity, provide combustion gas and combustion-supporting gas, burning is more continuous, and operating efficiency improves greatly simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of spray gun, comprise jet pipe 1, described jet pipe 1 is cylindrical elongate pipe, pipe shaft is provided with some small through hole 2, and described jet pipe one end 11 is for what close, and the other end is divided into two branch roads, one branch road is gas pipeline 4, be provided with burnt gas valve 3 between gas pipeline 4 and jet pipe 1, another branch road is combustion-supporting feed channel 6, is provided with combustion-supporting air valve 5 between combustion-supporting feed channel 6 and jet pipe 1.
Described jet pipe 1 is connected by threeway and elbow with branch road front end.
Described jet pipe 1 is formed in one with branch road front end.
Described combustion-supporting gas is compressed air.
Specific works process of the present utility model is as follows:
When aluminium casting mould needs heating, gas pipeline is connected fuel cartridge, and combustion-supporting feed channel connects air compressor machine, spray gun 1 is stretched into mold cavity inside, opens valve 3 and 5, in the igniting of jet pipe place, heats mould.The utility model can valve regulated flame size, after heating terminates, first closes fuel cartridge and air compressor machine, then valve-off.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for a person skilled in the art, do not departing under the utility model general idea prerequisite; can also make some changes and improvements, these also should be considered as protection domain of the present utility model.
