Description
Technical field
The utility model belongs to the workpiece cleaning field of surface treatment, more particularly, to a kind of nozzle for spraying fluid
And sand-blasting gun.
Background technology
Sand-blasting gun is widely used in the clearing up and processing process such as derusting, de-sludging, deburring of workpiece, sandblasting be using high pressure or
Sand material and air-flow are mixed to form the blasting jet that sand gas mixes by high-speed flow in sand blasting unit, and sand material is made to have certain speed
Degree striking work surface is to obtain the process of expected clearing up and processing effect.
The nozzle of sand-blasting gun is all internal diameter equal hollow cylindrical structure everywhere at present, when sand material is inputted from the side wall of nozzle
When, first, stream pressure is not big enough, the standard cleaned up is not achieved in injection pressure；Second is that since stream pressure is inadequate, sand material
Dispersion is uneven, the sandstone density bigger of the air-flow entrained with of close sand inlet, and the air-flow of the adjacent sidewalls opposite with sand inlet
The sandstone density of entrained with is smaller, that is, the sandstone density for the air-flow entrainment ejected is uneven everywhere, causes cleaning performance bad.
Invention content
For overcome the deficiencies in the prior art, the utility model a kind of injection pressure bigger is provided, the sandstone that ejects more
Uniform, cleaning performance is added more preferably to be used to spray the nozzle of fluid.
Technical solution adopted by the utility model to solve its technical problems is：A kind of nozzle for spraying fluid, packet
Nozzle body is included, the channel flowed for fluid is equipped in nozzle body, channel both ends are respectively formed fluid inlet and fluid outlet,
The necking section that internal diameter is less than channel internal diameter is formed on the channel, which is equipped with close to the side wall of fluid outlet into sand
Mouthful.
The setting that the utility model passes through necking section so that air-flow is after the smaller necking section of sectional area, and air-flow is from contracting
Injection pressure when the outflow of mouth section end increases, meanwhile, sand inlet is arranged close to necking section end so that sandstone is by larger pressure
Power moment impact disperses, and disperses evenly, and then cleaning performance is more preferably.
Further, the necking section includes the circulation section that section is equal everywhere, the second mistake expanded outwardly from circulation section
Section is crossed, the sand inlet is set on the second changeover portion side wall.
Further, the tapered expansion structure of the second changeover portion.The second mistake in tapered expansion is arranged in sand inlet
Cross in section, the injection pressure of air-flow gradually discharges, from sand inlet enter sandstone by the air-flow along the second changeover portion side wall by
Step dispersion, it is more uniform to be dispersed in sandstone of the same section everywhere in air-flow, and the side wall being obliquely installed ensure there is no
The dead angle of fluid flowing, avoids the delay of sandstone.
Further, the necking section further includes the first mistake shunk from channel to circulation section taper close to fluid inlet end
Cross section.The First Transition section that taper is shunk makes the fluid entered from fluid inlet be stepped up flowing pressure, is entirely pressurized
Cheng Gengjia is gentle, and structure design is more reasonable, not will produce the dead angle of fluid retention, and the flowing of fluid is more smooth.
The invention also discloses a kind of sand-blasting guns, include the ontology of pipe structure, and ontology rear end nozzle connects inlet tube,
Inlet tube is connect with the compression pump for providing highly pressurised liquid, and ontology is equipped with the control of control sand-blasting gun body interior pipeline break-make
Product, the ontology front end are connected with the nozzle, and the fluid inlet of the nozzle is connected with ontology front end nozzle, the spray
Sand inlet on mouth connects sand-feeding tube, and sand-feeding tube connects sand source.
Further, the control piece is operated pneumatic valve, by solenoid valve control, sandblasting gun body rear end as handle,
Linked switch is equipped at handle, control is for providing while linked switch is opened or closed by solenoid valve control operated pneumatic valve
The compression pump of highly pressurised liquid starts or stops.While opening sand-blasting gun, compression pump also opens simultaneously, the same luck of Liang Ge mechanisms
Make, it is easy to operate, it avoids in the original state high pressure liquid stream of opening sand-blasting gun without entrainment sandstone.
Further, the solenoid valve is fixed on the body.
Further, the gas that the connecting wire between the linked switch and compression pump and solenoid valve are connect with high-pressure air source
Pipe and inlet tube band together.
The utility model has the beneficial effects that：The injection pressure that necking section increases air-flow is set, and sand inlet is arranged in necking
The tail end of section, ensures the evenly dispersed of sandstone, finally improves parts in terms of uniform sandstone two from pressure and air-flow
Cleaning performance.
