The utility model content
In view of this, the purpose of this utility model is to provide a kind of high-pressure airless spraying gun, and the advantages such as trigger operated is laborsaving, the spray gun volume is little that it has can solve the shortcoming that existing high-pressure airless spraying gun exists.
The utility model high-pressure airless spraying gun, comprise rifle body, core assembly and valve seat, described rifle body comprises handle section and the valve pocket section that core assembly is installed, described core assembly comprises valve body, described valve seat is connected on valve body, and the coating spout that is provided with the coating chamber on valve seat and is communicated with the coating chamber is provided with outlet and is arranged on coating via hole on the coating chamber on described valve body, be provided with the material conveying tube that is coated with that is communicated with the coating via hole in described handle section.
Further, described core assembly also comprises the pull bar that is connected with spool on being arranged on the spool that coordinates with the coating spout in the coating chamber and being connected valve body, axially overlap successively along it on described pull bar block, sealing shroud, sealing block set and spring are arranged, described block is fixed on valve body, one end of described sealing shroud withstands on block, the other end of sealing shroud is fixed on the sealing block set, and an end of described spring withstands on the sealing block set, the other end of spring withstands on valve body;
Further, to withstand on the end on block be taper to described sealing shroud;
Further, described block is connected with valve body screw thread;
Further, also be provided with the sealing ring that coordinates with valve body on described sealing block set.
The beneficial effects of the utility model:
1, the utility model high-pressure airless spraying gun, it is coated with material conveying tube, and to be arranged at the rifle body inner, and spray gun has advantages of that contour structures is simple, volume is little, is not only applicable to the large tracts of land spraying, more is applicable to carry out spraying operation in little space; Coating chamber on the outlet that is coated with simultaneously material conveying tube and valve seat is communicated with, coating is without the back-moving spring chamber of core assembly, and this structure makes the back-moving spring pretightning force of core assembly less, and the power that therefore operates spray gun trigger is less, the spray gun rapid operation is conducive to reduce operator's labour intensity.
2, the utility model high-pressure airless spraying gun, it coordinates by sealing shroud and tie-rod sealing, and compares with the hermetically-sealed construction that pull bar coordinates by many groups sealing ring in conventional lance, and the dismounting of its seal is more convenient, and sealing effectiveness is better.
Description of drawings
Fig. 1 is the cutaway view of high-pressure airless spraying gun,
Fig. 2 is the zoomed-in view of P section in Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment high-pressure airless spraying gun, comprise rifle body 1, core assembly and valve seat 2, described rifle body 1 comprises handle section 111 and the valve pocket section 112 that core assembly is installed, described core assembly comprises valve body 3, described valve seat 2 is connected on valve body 3, and the coating spout 22 that is provided with coating chamber 21 on valve seat 2 and is communicated with coating chamber 21, be provided with outlet on described valve body 3 and be arranged on coating via hole 31 on coating chamber 21, be provided with in described handle section 111 be communicated with coating via hole 31 be coated with material conveying tube 4.
In the present embodiment, the described material conveying tube 4 that is coated with is structure independently, and being coated with material conveying tube 4 can make with resistant material, and the life-span is long.Certainly in different embodiments, the described material conveying tube 4 that is coated with also can be with valve body 3 and makes integrative-structure, a coating namely directly is set on valve body 3 carries the duct, also can realize the purpose of this utility model.
The present embodiment high-pressure airless spraying gun, it is coated with material conveying tube 4 and is arranged at rifle body 1 inside, and spray gun has advantages of that contour structures is simple, volume is little, is not only applicable to the large tracts of land spraying, more is applicable to carry out spraying operation in little space; Coating chamber 21 on the outlet that is coated with simultaneously material conveying tube 4 and valve seat 2 is communicated with, coating is without the back-moving spring chamber of core assembly, this structure makes back-moving spring 11 pretightning forces of core assembly less, therefore the power that operates spray gun trigger is less, the spray gun rapid operation is conducive to reduce operator's labour intensity.
