Abstract
The utility model belongs to a vacuum generator which is composed of a valve body, a nozzle, a shrink hole, a larynx hole, an expansion hole and an air suction port. The shrink hole, the larynx hole and the expansion hole are arranged in the valve body. The nozzle is arranged on the valve body which approaches to one side of the shrink hole. The shrink hole, the larynx hole, the expansion hole and the nozzle are positioned on the same shaft line. The air suction port is arranged in the valve body at the side of the nozzle and the shrink hole. When the vacuum generator works, high pressure air source ejects gas into the valve body through the nozzle. Vacuum is formed in the air suction port. A working piece can be sucked through a sucking disk. The utility model has the advantages of simple structure, easy manufacture, small volume, light weight, low cost, higher vacuum degree, little air consumption and long service life. The vacuum generator of the utility model can be used in various industries, such as electronic industry, light industry, food industry, paper industry, printed industry, etc.
Description
The utility model belongs to a kind of vacuum generating device.
At present the black vacuum equipment that more generally adopts mainly is the mechanical type vavuum pump, and the mechanical type vavuum pump is to rely on the reciprocating motion of parts in the driven by motor pump or gas that certain space is extracted in gyration out and obtain vacuum.Because the mechanical type vavuum pump need be furnished with special motor-driven, its shortcoming is that complex structure, volume are big, cost is high, the life-span is short.
The present utility model task provide a kind of simple in structure, volume is little, noise is low, cost is low, do not need motor-driven black vacuum generating means.
The utility model is characterised in that: it comprises valve body, nozzle, air entry, shrinkage hole, larynx hole, expanded bore and air entry, in valve body, be provided with shrinkage hole, larynx hole and expanded bore, near on the side valve body of shrinkage hole a nozzle is being housed, shrinkage hole, larynx hole, expanded bore and nozzle are provided with air entry in a side of valve body inner nozzle and shrinkage hole on same axis.
Assembling one silencer on the close valve body of expanded bore one side.
Be provided with a vacuum chamber in valve body, vacuum chamber communicates with air entry, establishes a piston in the vacuum chamber, and the pin of posting a letter is set on the piston, and piston links to each other with a spring.
Accompanying drawing 1 is the mechanical construction drawing of vacuum generator.
Below in conjunction with accompanying drawing the utility model is further described.In valve body ［ 6 ］, be provided with shrinkage hole ［ 7 ］, larynx hole ［ 5 ］, expanded bore ［ 3 ］, air entry ［ 9 ］ and vacuum chamber ［ 11 ］, going up installation one nozzle ［ 8 ］ near the valve body ［ 6 ］ of shrinkage hole ［ 7 ］ one sides, shrinkage hole ［ 7 ］, larynx hole ［ 5 ］, expanded bore ［ 3 ］ and nozzle ［ 8 ］ are on an axis, going up installation one silencer ［ 1 ］ near the valve body ［ 6 ］ of expanded bore ［ 3 ］ one sides, one piston ［ 2 ］ is set in vacuum chamber ［ 11 ］, piston ［ 2 ］ links to each other with a compression spring ［ 4 ］, inherent shrinkage hole ［ 7 ］ one sides of valve body ［ 6 ］ are provided with air entry ［ 9 ］, vacuum chamber ［ 11 ］ communicates with air entry ［ 9 ］, locates to link to each other with a sucker ［ 10 ］ by pipeline at air entry ［ 9 ］.
During work, high-pressure air source feeds gases at high pressure to nozzle ［ 8 ］, nozzle ［ 8 ］ ejection high velocity air, air-flow is discharged through shrinkage hole ［ 7 ］, larynx hole ［ 5 ］, expanded bore ［ 3 ］, eliminate noise through silencer ［ 1 ］ again, because the effect of entrainmenting of jet, produce vacuum in the air entry ［ 9 ］, just can pick up workpiece by sucker ［ 10 ］, meanwhile, piston overcomes the elastic force of compression spring ［ 4 ］ under the atmospheric pressure effect, move downward, the drive pin ［ 12 ］ of posting a letter is depressed microswitch ［ 13 ］, sends the signal of telecommunication.Behind the cutoff high source of the gas, no longer be vacuum in the air entry ［ 9 ］, sucker ［ 10 ］ loses suction, puts down workpiece simultaneously, resets at the effect lower piston ［ 2 ］ of spring ［ 4 ］, and the signal of telecommunication disappears, and so far finishes once action.
Vacuum generator provided by the utility model is compared with the black vacuum pump, have simple in structure, volume little (3.5 * 2 * 6cm), in light weight, vacuum higher (720mmHg), air consumption little (90 liter/mins), handling ease, cost is low, and the life-span is long, because vacuum generator is equipped with silencer, makes its work noise little. Vacuum generator can send the signal of telecommunication. Be the ideal device of realization machine-electricity-gas integral, can be widely used in the industries such as electronics, light industry, food, papermaking, printing.
