Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Refer to Fig. 1 to Fig. 5, the utility model provides a kind of novel high-pressure spray gun, comprise rifle body 1, handle 2 that rifle body 1 one end is extended downwards and the lower kettle 3 be located at below rifle body 1, lower kettle 3 inside is provided with suction pipe 4, handle 2 lower end is provided with snap joint 5, and rifle body 1 front end is provided with rifle head 6, is provided with the coating pin 7 of through rifle body in rifle body 1, rifle body 1 afterbody is provided with the coating pin adjusting device 8 be connected with coating pin 7, is provided with a gas storage space 9 in described rifle body 1 front portion; Described rifle body 1 is provided with an air volume regulating device 10 connected with gas storage space 9; A safety valve 11 connected with lower kettle 3 inner space is provided with above described lower kettle 3; Described air volume regulating device 10 is connected with safety valve 11 by a tracheae 12; Described rifle head 6 comprises nozzle 13, and nozzle 13 is covered with an amplitude modulation spring 14; Described amplitude modulation spring 14 is connected with a stream cap 15 matched with nozzle 13; Described stream cap 15 is connected with a stream hatband 16 matched with it, and stream hatband 16 is threaded connection and is fixed on rifle body 1.
Described handle 2 inside is provided with an air inlet pipeline 17 through each other with snap joint 5; An air flue pipeline 18 connected with air inlet pipeline 17 is provided with in described rifle body 1; Described air flue pipeline 18 connects with gas storage space 9; Described rifle body 1 afterbody is provided with an air releasing device; Described air releasing device comprises disappointing valve seat 19, filtering head 20; Described disappointing valve seat 19 is positioned at air flue pipeline 18; Described disappointing valve seat 19 one end has an opening 21; Be provided with a gas bleeder valve 22 in described disappointing valve seat 19, opening 21 blocks by gas bleeder valve 22; Described gas bleeder valve 22 is connected with a disappointing spring 23; Described disappointing spring 23 is fixed on a nut 24, and nut 24 is positioned at air flue pipeline 18.
Described stream cap 15 center is provided with a mesopore 25; Described nozzle 13 comprises the shower nozzle 26 being positioned at mesopore place; Described shower nozzle 26 external diameter and mesopore 25 diameter ratio are 4.7:2.8.
Using method of the present utility model is as follows:
When needing to use high-pressure spray gun to carry out spray coating operations, first be connected with external gas source by the snap joint 5 of flexible pipe by handle 2 lower end, after opening external gas source, gas enters into the air inlet pipeline 17 li in handle along snap joint 5, because air inlet pipeline 17 and air flue pipeline 18 connect, and air flue pipeline 18 and gas storage space 9 connect, therefore after gas enters air inlet pipeline 17, enter into air flue pipeline 18 thereupon, then enter in gas storage space 9, the air-flow entering its space can gather by gas storage space 9, play the effect of an accumulator tank, and energy strengthening flow pressure, balanced gas shock, the atomization quality that coating is atomized when spraying is protected, when the gas storage space 9 of accumulated gases in rifle body front portion, part gas enters in tracheae 12 by air volume regulating device 10, enter in lower kettle 3 finally through safety valve 11, air pressure in lower kettle 3 is changed, full-bodied coating along suction pipe 4 moment by be drawn onto in rifle body 1, spray eventually through nozzle atomization, therefore the existence of air volume regulating device 10 makes full-bodied coating can be sucked out lower kettle easily, the situation causing suction pipe 4 cannot draw lower kettle 3 inside courtyard because dope viscosity is too high can not be there is.
If when needing to regulate the atomization Amplitude Width of coating in spraying process, convection current hatband 16 carries out rotation when making it be subjected to displacement toward handle 2 direction, stream cap 15 retreats thereupon, the nozzle 13 now matched with stream cap 15 protrudes to flowing outside cap 15 gradually, when nozzle 13 exposes to the projection outside stream cap 15 more, the atomization Amplitude Width that nozzle 13 sprays is wider, if in spraying process, when finding that atomization Amplitude Width is wide, stream hatband 16 can be made to carry out displacement towards the opposite direction of handle 2, now the elastic force of amplitude modulation spring 14 makes stream cap move forward, nozzle 13 expose to stream cap 15 outside projection then start to diminish, the atomization Amplitude Width that nozzle 13 sprays starts to narrow, owing to just can be changed the width of the atomization amplitude that nozzle 13 sprays by rotating flow hatband 16, therefore in spraying process, can be regulated atomization Amplitude Width by stream hatband 16 according to needing the size of spraying area, this atomization amplitude adjusted mode can not only accelerate the spray efficiency of larger spraying area, and the coating quality of less spraying area can be ensured, without the need to changing spray gun because spraying area is not of uniform size in spraying process, avoid the trouble that staff changes spray gun, and in a general case, the length that nozzle 13 protrudes stream cap 15 plane is 1.5mm, this protrusion length adapts to most spraying situation, and nozzle 13 at every turn ejection coating number, regulate by coating pin adjusting device 8 needed for actual.
When the gas of external gas source constantly enters in rifle body 1, if when the air pressure in rifle body 1 exceeds safe air pressure, cross strong air pressure and can promote gas bleeder valve 22, gas bleeder valve 22 is moved toward nut 24 direction, the opening 21 of disappointing valve seat no longer blocks by final gas bleeder valve 22, and the gas in rifle body 1 enters in disappointing valve seat 19 along the opening 21 of disappointing valve seat, then be discharged to rifle body 1 through nut 24 from filtering head 20, because filtering head 20 has filter effect, therefore the gas of discharging outside rifle body 1 is all safe gas, can not impact the health of staff, when gas is discharged after outside rifle body 1, air pressure numerical value in rifle body 1 returns to safe range, now, the spring 23 that loses heart makes gas bleeder valve 22 reset by the elastic force of self, gas bleeder valve 22 is made again to be blocked by the opening 21 of disappointing valve seat.
Stream cap 15 and the combined situation of nozzle 13 determine the atomizing effect of spray gun, when shower nozzle 26 external diameter of nozzle is 4.7mm and stream cap mesopore 25 diameter is 2.8mm, shower nozzle 26 external diameter is 4.7:2.8 with stream cap mesopore 25 diameter ratio, now the atomizing effect of spray gun is best, can ensure that spray gun uses high viscosity coating medium to be atomized, stream cap 15 liang of ear angular apertures are strengthened, strengthen the pincer attack dynamics of fan-shaped spraying swath, be aided with the atomization aperture around stream cap mesopore 25, can in minimizing bounce-back during direct spraying high viscosity coating under high pressure draught, strengthen adhesive force, promote uniform atomizing spraying.
General high-pressure spray gun only can carry out the atomization of about about 20 seconds to coating, once exceed this time period, spraying coating out just can become larger particle from mist particles, causes coating quality extreme difference, and when atomizing particle is excessive, spray gun even can be made to spray coating, and novel high-pressure spray gun of the present utility model is by self structure, nebulisation time can be made to maintain about 30 seconds, due to the prolongation of nebulisation time, spraying can be made more even, ensure coating quality.
