Abstract

The utility model relates to a spraying gun without gas, which belongs to the field of spray painting without the gas. The disadvantage of the accumulation of paint caused by rough spraying gun line in the prior art is overcome. A reset spring is arranged on the tail of the spraying gun which is only provided with a soft sealing element. Thus, the flowing part of the paint does not have dead angles, and is oily and smooth. The accumulating and the plugging phenomena of the paint are reduced; the reliability of the high pressure sealing and the gun closing time are raised; the elasticity of the sealing ring can be conveniently regulated; the operation is simple; the leakage is eliminated; the cost is reduced; the service life is prolonged.

Description

Airless spray gun
The utility model relates to a kind of airless spray gun, belongs to the airless spraying field.
Airless spray gun of the prior art, the coating passage is typically provided with spring, and the rifle spool is provided with guider and multiple-sealed circle, therefore makes the not smooth piling that causes of circuit.Be socketed with back-moving spring as Chinese patent 92239334.6 disclosed " electric spray gun " beyond the Great Wall at pump, easily spring blocking uses inconvenience, and spray gun can not sufficiently and reasonably be used.
The purpose of this utility model is that a kind of coating passage of manufacturing does not have dead angle, circuit smoothness, prevents to stop up, and only place's sealing ring need be set and just can stop a leak, and reduces cost the airless spray gun that spraying effect is good.
To achieve these goals, by the following technical solutions: this spray gun is provided with back-moving spring at afterbody, and the external diameter of rifle spool is less than coating passage internal diameter, and the rifle seat design becomes big valve port and dual valve.Clamp nut one end that is close to sealing ring is in the rifle external body.Back-moving spring clamps valve rod by tapered opening cover, nut.
The utility model is arranged on the spray gun afterbody with back-moving spring, spray gun only has been equipped with place soft seal parts, the external diameter of adding the rifle spool is less than coating passage internal diameter, the rifle valve seat has adopted big valve port and dual valve port, make the rifle spool can own centering rifle valve seat the center, need not in the coating passage, guider be set, can make the coating position of flowing through not have the dead angle, slick and sly smooth, reduced the piling phenomenon of blocking; The reliability and the pass rifle time of high pressure sealing have been strengthened; Clamp nut one end of sealing ring can conveniently be regulated the degree of tightness of sealing ring in the rifle external body, and is easy and simple to handle and stop a leak, reduced cost; Back-moving spring is to transmit power by the valve rod that nut and opening sleeve compress the rifle spool, has avoided having prolonged service life with two nuts and tightly with valve rod and disconnected defective.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is airless spray gun one an example structure schematic diagram.
Fig. 2 is a rifle valve seat construction schematic diagram.
At the airless spray gun afterbody back-moving spring 7 is set, back-moving spring 7 clamps valve rod by tapered opening cover 6, nut 8.Rifle spool 3 is less than coating passage internal diameter, and is contactless with the coating vias inner walls.Rifle valve seat 2 is designed to valve port internal diameter 5.5mm, the dual valve port of the big valve port of the long 2.5mm of inner cone and 72 °, 50 °.Clamp nut 9 one ends that are close at sealing ring 1 are in rifle body 5 outsides.Airless spray gun is under the high pressure of 35MPa, and cocking 4 compresses the valve rod of rifle spool 3 by nut 8 and tapered opening cover 6, has spurred rifle spool 3, and coating flows to nozzle and sprays.When not needing work, the openhanded trigger 4 of opening, rifle spool 3 is closed spray gun forward under the effect of spring force.
