Abstract
The utility model discloses a gas-liquid mixing device for a gas spray gun; the handle position is added with a liquid inlet pipe parallel with a gas inlet pipe, the bore position is added with a liquid outlet pipe communicated with the liquid inlet pipe and parallel with a gas outlet pipe, and a nozzle is firmly arranged on the gunpoint position; wherein the gas outlet pipe is sleeved outside the liquid outlet pipe and takes a tapered shape on the position near the front end of the liquid outlet pipe, which makes the gas flow form a high pressure area on the position after passing through the tapered shape structure; the liquid is taken out under the action of differential pressure in order to realize the gas-liquid mixture and then sprayed from the nozzle, which thereby reaches the double functions of simultaneously spraying gas and liquid. As the gas-liquid mixing device for the gas spray gun is improved, compared with the gas-liquid mixing device in the existing technology, the improved gas-liquid mixing device obviously reduces an adapter; therefore, the utility model has the advantages of the simple structure, the easy processing and the convenient assembly, and reduces components, namely reduces the possibility of the poor between components, which thereby further ensure the gas tightness of the whole gas spray gun.
Description
Technical field
The utility model relates to a kind of Liqiud-gas mixing device of jet gun.
Background technology
Jet gun in the past can only be jet, and can not hydrojet.Afterwards, in order to carry out other work of treatment, just there had been jet gun as shown in Figure 1, 2 to come out to required jet object is simultaneously jet.
This jet gun mainly is to set up a feed tube 12 parallel with air inlet pipe 11 at handle 1 position, set up with feed tube 12 at bore 2 positions and to communicate, the drain pipe 22 parallel with escape pipe 21, and drain pipe 22 is nested with outside escape pipe 21, and increase by one at muzzle 3 places and can make gas, the crossover sub 4 that liquid mixes, nozzle 5 is installed on the crossover sub 4, the center 41 of this crossover sub 4 formation gas circuit that communicates with escape pipe 21,42 communicate with drain pipe 22 and to form the liquid road on every side, the front end of crossover sub 4 is pre-small post-large Taper Pipe shape, be that whole gas circuit is gradually-reducing shape in the position near liquid road end, by this pre-small post-large gradually-reducing shape structure, behind air-flow process crossover sub 4, promptly form the higher-pressure region in the place ahead of crossover sub 4, liquid is taken out of under differential pressure action, and at the place ahead of crossover sub 4 realization gas, liquid mixes, spray by nozzle 5 again, thereby reach simultaneously jet, the double effects of liquid.
The detailed Liqiud-gas mixing device of seeing existing jet gun is not difficult to find, the crossover sub of setting up at muzzle 3 places 4, and not only complex structure is processed trouble, and assembling is also inconvenient, also influences the air-tightness of whole jet gun.
The utility model content
The purpose of this utility model promptly is to provide a kind of Liqiud-gas mixing device of jet gun, makes simple in structure, handling ease, and is easy to assembly, and guarantees the air-tightness of whole jet gun.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of Liqiud-gas mixing device of jet gun, set up a feed tube parallel with air inlet pipe at the handle position, set up with feed tube at the bore position communicate, the drain pipe parallel with escape pipe, nozzle is installed in the muzzle place, wherein: escape pipe is nested with outside drain pipe, and escape pipe is gradually-reducing shape in the position near the drain pipe front end, make air-flow through after this gradually-reducing shape structure, promptly form the higher-pressure region in this position, liquid is taken out of under differential pressure action, realize that gas, liquid mix,, thereby reach double effects jet simultaneously, liquid again by the nozzle ejection.
Wherein, described drain pipe front end directly stretches in the jet pipe of nozzle, thereby makes escape pipe be gradually-reducing shape in the position near the drain pipe front end indirectly, and its effect is constant.
Insert in the escape pipe described nozzle inner end, until the position near the drain pipe front end, thereby makes escape pipe be gradually-reducing shape in the position near the drain pipe front end indirectly, and its effect is constant.
Set up the control valve of regulating the flow size on described feed tube or the drain pipe.Control valve is screw shaped, and screw rod is arranged on the valve seat, and intert in feed tube or drain pipe the inner of screw rod, is used to control feed liquor amount or liquid outlet quantity, and the outer end of screw rod stretches outside valve seat, be convenient to adjusting screw(rod) into and out of.
After adopting said structure, the utility model is owing to the Liqiud-gas mixing device to jet gun is improved, make the Liqiud-gas mixing device after the improvement obviously reduce by a crossover sub than Liqiud-gas mixing device of the prior art, so, simple in structure, handling ease, easy to assembly, and, reduce member, promptly reduced the possibility that cooperates poor air-tightness between the member, thereby further guaranteed the air-tightness of whole jet gun.And the utility model has been owing to set up control valve on feed tube or drain pipe, so, can control the size of fluid flow by control valve according to needs, and then promote practicality of the present utility model.

The specific embodiment
Please referring to shown in Figure 3, the Liqiud-gas mixing device of the jet gun that the utility model discloses, be to set up a feed tube 12 parallel at handle 1 position with air inlet pipe 11, set up with feed tube 12 at bore 2 positions communicate, the drain pipe 22 parallel with escape pipe 21, nozzle 5 is installed in muzzle 3 places.
Cooperate shown in Fig. 4,5, key of the present utility model is: escape pipe 21 is nested with outside drain pipe 22, and escape pipe 21 is gradually-reducing shape in the position near drain pipe 22 front ends.
Specifically, insert in the escape pipe 21 nozzle 5 inner ends, until position near drain pipe 22 front ends, and, drain pipe 22 front ends directly stretch in the jet pipe 51 of nozzle 5, thereby make escape pipe 21 be gradually-reducing shape in the position near drain pipe 22 front ends indirectly, after this gradually-reducing shape structure of air-flow process, promptly the front position at drain pipe 22 forms the higher-pressure region, liquid is taken out of under differential pressure action, realize that gas, liquid mix,, thereby reach double effects jet simultaneously, liquid again by nozzle 5 ejections.Like this, the utility model is compared with Liqiud-gas mixing device of the prior art, obviously reduced by a crossover sub 4, so structure is simpler, processing is easier, assembles more convenient, and, reduce member, promptly reduced the possibility that cooperates poor air-tightness between the member, thereby further guaranteed the air-tightness of whole jet gun.
