Description

The two-tube spray gun of self-absorption adjustable

The utility model belongs to injection apparatus, especially belongs to two-tube spray gun.

The spray gun of manufacturer production has two kinds at present, a kind of is air blow gun, a kind of is paint spray gun, air blow gun only is to utilize gases at high pressure to dry up or cleaning objects, paint spray gun has plenty of by pressurized tank (in coating leaves in) carries coating, have plenty of and carry paint can on the rifle body and spray the troublesome poeration clumsiness in entering jar by compressed air again.

The purpose of this utility model is to provide a kind of can cleaning and can blowing the two-tube spray gun of the self-absorption adjustable that all dries up to dope layer at once of air blow gun and paint spray gun that integrate.

The technical scheme that the utility model adopted is that the two-tube spray gun of self-absorption adjustable comprises spraygun body, handle, carrier pipe, sprayer body, suction nozzle, liquid inlet port, valve control system are arranged on the spraygun body, sprayer body has four cavitys, be respectively A chamber, B chamber, C chamber, D chamber, the A chamber links to each other with air delivery pipe, B chamber and liquid delivery tube join, and communicate with the C chamber, C chamber and control valve join, the A chamber is to one section contraction section is arranged between the B chamber, one circular protrusion is arranged in the B chamber, and its height is flat with the center line in C chamber, and the bottom surpasses the shrinkage hole in C chamber.

C of the present utility model chamber becomes an oblique angle with the B chamber on the plane perpendicular to D chamber center line, angle is preferably 8 ° at 5-15 °, and then the atomizing effect of coating is better.

Advantage of the present utility model: when compressed air pressure during greater than 0.4Mpa, the coating hoisting depth can reach 0-5m and need not pressurized tank or carry a jar work high above the ground, the long distance operation is quite convenient, by eddy current atomization, quite well-to-do to the coating channels designs, coating solute diameter all can spray with interior at φ 0.5mm like this, and is less demanding to coating solute thickness, atomizing area size is by cut-out governing, and spray amount is regulated by control valve.

Fig. 5 is the B-B profile of Fig. 4

Wherein: 34D chamber, 33C chamber, 32B chamber, 1 spraygun body, 11 valve control system 111 feed liquor spools, 112 fluid hole 113 sealing rings, 114 inlet opening 115 nuts, 116 air inlet spool 117 ventholes, 118 air admission hole 119 springs, 12 suction nozzle 13 liquid inlet ports, 14 carrier pipe 2 handles, 3 sprayer body 31A chamber 35 control valves, 36 contraction sections, 37 circular protrusions, 38 shrinkage holes, 39 nozzles

Below in conjunction with view the utility model is described in detail

Comprise spraygun body 1, handle 2, valve control system 11, suction nozzle 12, liquid inlet port 13, carrier pipe 14, control valve 35, sprayer body 3, nozzle 39 as the two-tube spray gun of Fig. 1 self-absorption adjustable shown in Figure 2, air flue and fluid passage have separately independently passage and control system, gas, liquid mix in sprayer body 3, through nozzle 39 sprayings, suction nozzle 12 connects air compressor machine, and liquid inlet port connects paint can.

As shown in Figure 3, control system 11 air inlets of valve, feed liquor is controlled respectively, they comprise spool respectively, spring 119, sealing ring 113, nut 115, sealing ring 113 is enclosed within the spool, air admission hole 118, venthole 117 are positioned at the two ends of air seal circle 113, inlet opening 114, fluid hole 112 lay respectively at the two ends of liquid sealing ring 113, spring 119 is contained between spool and the nut 115, air inlet, feed liquor spool can contact with handle 2, and it is nearer with handle 2 distances that air inlet spool 116 is higher than feed liquor spool 111.

Gas, liquid turnover control principle: press lower handle 1, handle 1 backs down air inlet spool 116 earlier, compressed air enters from air admission hole 118, enter air shooter 14 from nozzle 39 ejections from venthole 117, reach the purpose of air blowing, continue to press lower handle 1, feed liquor spool 111, backed down simultaneously, liquid (coating) enters fluid hole 112 influent carrier pipes 14 from inlet opening 114, and gas, liquid mix in sprayer body 3, ejection reaches the spraying purpose from nozzle 39, release handle 1 stops hydrojet earlier and continues to blow, whole release handle 1, and work stops.

As shown in Figure 4, sprayer body 3 has four chambeies, be respectively A chamber 31, B chamber 32, C chamber 33, D chamber 34, A chamber 31 links to each other with air delivery pipe, and B chamber 32 joins with liquid delivery tube, and communicate with C chamber 33, C chamber 33 joins with control valve 35, and there is one section contraction section 36 in the A chamber between 31 to the B chambeies 32, and a circular protrusion 37 is arranged in the B chamber 32, the center line in its height H one end and C chamber 33 is flat, and the other end surpasses the shrinkage hole 38 in C chamber 33.After air intake valve is opened, compressed air enters B chamber 32 from A chamber 31, B chamber 32 links to each other with nozzle 39, and nozzle 39 belongs to the sudden expansion type, compressed air is given C chamber 33 like this, D chamber 34 vacuumizes until the whole liquid pipeline, and causes the whole liquid pipeline to produce negative pressure, and liquid storage all can be sent to certain altitude in any vessel like this.
