Abstract
This utility model relates to wet blast device technique field, particularly to a kind of wet blast rifle, including gun body, sandpipe joint, blast nozzle, the gentle joint of air nozzle, gun body has first passage and the second channel connected with first passage, blast nozzle and air nozzle are installed in first passage successively, gas joint is connected to the end of first passage, is provided with non-return pearl between gas joint and air nozzle, and sandpipe joint is connected to the end of second channel.First passage of the present utility model disposably machines, and improves the axiality of first passage, it is to avoid blast nozzle and air nozzle can not install produced impact with one heart；Further, since this utility model adds non-return pearl, when there being inverted draft, non-return pearl directly blocks gas circuit, thus can avoid the destruction of siphonage.
Description
Technical field
This utility model relates to wet blast device technique field, particularly to a kind of wet blast rifle.
Background technology
The one of institute's use sand blasting units such as the surface process of workpiece, the sand blasting unit of prior art is by being sprayed to workpiece by the serosity containing grinding agent in liquid, carries out the surface process of workpiece.The sand-blasting gun that wet blast device is used includes: have the gun main body that slurry stream is entered the room；Gas injection (air jet) parts of injection gas (air)；Nozzle (nozzle) parts etc. of serosity are sprayed together with the gas of injection.
At present, the sand-blasting gun of prior art is usually present problems with: 1) sand-blasting gun is all divided into two parts on the market, gun body and blast nozzle mould set connection and form, after so assembling, bigger error will be produced for the axiality of valve and nozzle, affect sand production rate and sandblasting dynamics；2) compressed air hose of common sand-blasting gun is all that the larynx hoop used is tightened fixing on the market so that efficiency of assembling is low；3), there is the situation that sandblasting dynamics is inadequate in the valve of common sand-blasting gun and nozzle distance about 5mm on the market；4) valve of common sand-blasting gun is connected with nozzle through type on the market, terminates moment in sandblasting, after valve the most not jet, can produce siphonage, a small amount of sand is sucked trachea, directly destroys pneumatic element, even if installing check valve, also damages very fast.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provides a kind of wet blast rifle, and this wet blast rifle can solve the technical problem in above-mentioned background technology.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of wet blast rifle, including gun body, sandpipe joint, blast nozzle, the gentle joint of air nozzle, described gun body has first passage and the second channel connected with described first passage, described blast nozzle and described air nozzle are installed in described first passage successively, described gas joint is connected to the end of described first passage, being provided with non-return pearl between described gas joint and described air nozzle, described sandpipe joint is connected to the end of described second channel.
As a kind of improvement of wet blast rifle described in the utility model, described gas joint screw thread is connected to the end of described first passage, and described sandpipe joint screw thread is connected to the end of described second channel, and the end of sandpipe joint is provided with installation protuberance.
As a kind of improvement of wet blast rifle described in the utility model, described blast nozzle, described air nozzle and described first passage are formed and converge district, and the width H converging district is 18 ~ 25mm.
As a kind of improvement of wet blast rifle described in the utility model, described in converge the width H in district be 20mm.
As a kind of improvement of wet blast rifle described in the utility model, described gun body also has stop part, and described stop part props up described blast nozzle.
As a kind of improvement of wet blast rifle described in the utility model, the outer wall of described gun body has hangers and groove position.
As a kind of improvement of wet blast rifle described in the utility model, also include that quick connector, described quick connector are connected with described gas joint screw thread.
The beneficial effects of the utility model are: this utility model includes gun body, sandpipe joint, blast nozzle, the gentle joint of air nozzle, gun body has first passage and the second channel connected with first passage, blast nozzle and air nozzle are installed in first passage successively, gas joint is connected to the end of first passage, being provided with non-return pearl between gas joint and air nozzle, sandpipe joint is connected to the end of second channel.First passage of the present utility model disposably machines, and improves the axiality of first passage, it is to avoid blast nozzle and air nozzle can not install produced impact with one heart；Further, since this utility model adds non-return pearl, when there being inverted draft, non-return pearl directly blocks gas circuit, thus can avoid the destruction of siphonage.

Detailed description of the invention
Below in conjunction with detailed description of the invention and Figure of description, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
As shown in Fig. 1 ~ 4, a kind of wet blast rifle, including gun body 1, sandpipe joint 2, blast nozzle 3, the gentle joint of air nozzle 45, gun body 1 has first passage 11 and the second channel 12 connected with first passage 11, blast nozzle 3 and air nozzle 4 are installed in first passage 11 successively, gas joint 5 is connected to the end of first passage 11, is provided with non-return pearl 6 between gas joint 5 and air nozzle 4, and sandpipe joint 2 is connected to the end of second channel 12.
Preferably, gas joint 5 is threadedly connected to the end of first passage 11, and sandpipe joint 2 is threadedly connected to the end of second channel 12, and the end of sandpipe joint 2 is provided with installation protuberance 21, installs protuberance 21 and is used for sandpipe, pricks locking by larynx hoop.
Preferably, blast nozzle 3, air nozzle 4 and first passage 11 are formed and converge district 7, and the width H converging district 7 is 18 ~ 25mm, meets the demand of use in the range of this；The width H converging district 7 is set to 20mm by present embodiment, because actually water spray is sprayed with dry and differ, when water sprays, we need to increase the width converging district 7, is so conducive to increasing sandblasting amount and sandblasting dynamics, thus improves sandblasting efficiency.
Preferably, gun body 1 also has stop part 13, and stop part 13 props up blast nozzle 3, prevents blast nozzle 3 to be rushed out in sandblasting procedures.The outer wall of gun body 1 has hangers 14 and groove position 15, when gun body 1 uses mounting, it is possible to use hangers 14 uses bolt fixed mode to install；When gun body 1 plug-in type is installed, groove position 15 is to use standard axle snap ring to fix gun body 1, and groove position 15 may be used for gun body 1 and installs the regulation of insertion depth.
This utility model also includes that quick connector 8, quick connector 8 are used for connecting compressed air hose, due to the setting of quick connector 8, so that trachea is inserted soon is connected to quick connector 8, substantially increases efficiency of assembling；Quick connector 8 is threadeded with gas joint 5, certainly can also adopt and connect in other ways, be not especially limited here.
The announcement of book and teaching according to the above description, above-mentioned embodiment can also be changed and revise by this utility model those skilled in the art.Therefore, this utility model is not limited to above-mentioned detailed description of the invention, and any conspicuously improved, replacement or modification that every those skilled in the art are done on the basis of this utility model belong to protection domain of the present utility model.Although additionally, employ some specific terms in this specification, but these terms are merely for convenience of description, this utility model is not constituted any restriction.
