Abstract
An air valve assembly device of a paint gun comprises an air valve spool, an air valve seat, an air valve inlet valve, a nut, a sealing part and a sealing ring, wherein the air valve seat and the air valve inlet valve are sequentially sleeved on the air valve spool, the nut is mounted in the air valve seat, the sealing part is arranged between the air valve seat and the air valve spool, and the sealing ring is mounted on the air valve inlet valve. The air valve assembly device is characterized in that the air valve seat and the air valve inlet valve are cast integrally. The air valve assembly device is simple in assembly and fine in sealing performance.
Description
Technical field
The utility model relates to a kind of paint spray gun air valve device, relates in particular to a kind of air valve assembly device of paint spray gun.
Background technique
The air valve assembly device is the important composition parts of paint spray gun, is that control enters the compressed-air actuated switch of paint spray gun.Existing paint spray gun air valve assembly device structure comprises air valve core 1, air valve gate seat 2, Sealing 3, air valve suction valve 4, seal ring 5 as shown in Figure 1, and air valve gate seat 2 and air valve core 1 are by being threaded.Be provided with groove in the air valve gate seat 2 Sealing 3 is installed, air valve suction valve 4 and air valve gate seat 2 are by being threaded, and air valve suction valve 4 is installed on the air valve core 1.Air valve suction valve 4 rear ends are equiped with seal ring 5.In the time of use, air valve suction valve 4 makes and produces sealing between Sealing mounted thereto 3 and the air valve gate seat 2 by the screw thread extruding.In the practicality, promote air valve core 1 its generation is moved axially, and then air valve core 1 is separated with air valve suction valve 4, thereby realize the opening and closing of air inlet.Adopt the air valve assembly device of this structure, can realize controlling the purpose that enters the paint spray gun pressurized gas, but have following shortcoming: 1, air valve suction valve 4 and air valve gate seat 2 are by being threaded, occur out-of-alignment phenomenon between two accessories easily, thereby cause air valve core 1 and air valve suction valve 4 poor fits to cause gas leakage; 2, air valve gate seat 2 and air valve suction valve 4 splits design require two accessory assembling backs coaxial again, make that air valve assembly device accessory is various, and assembling is complicated.
The model utility content
The utility model aims to provide a kind of paint spray gun valve valve assembly device simple, good seal performance that assembles.
The technological scheme that the utility model adopted is: a kind of air valve assembly device of paint spray gun, comprise air valve core, air valve gate seat, air valve suction valve, nut, Sealing, seal ring, be set with air valve gate seat, air valve suction valve on the air valve core in turn, be equiped with nut in the air valve gate seat, be provided with between air valve gate seat and the air valve core on Sealing, the air valve suction valve seal ring is installed, it is characterized in that: the integrated one that is cast as of described air valve gate seat and air valve suction valve.
The beneficial effects of the utility model are: air valve gate seat and air valve suction valve adopt the integral type casting, have overcome existing air valve gate seat and the air valve suction valve disalignment defective that is threaded and produces.Simultaneously because air valve gate seat and air valve suction valve adopt integrated casting, not only process simple and convenient, and be convenient to installation and removal.
Description of drawings
Accompanying drawing 1 is the existing structure schematic representation of the air valve assembly device of a kind of paint spray gun of the utility model;
Accompanying drawing 2 is improvement structural representations of the air valve assembly device of a kind of paint spray gun of the utility model;
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:
Embodiment of the present utility model as shown in Figure 2, a kind of air valve assembly device of paint spray gun, comprise air valve core 1, air valve gate seat 2, air valve suction valve 3, nut 4, Sealing 5, seal ring 6, be set with air valve gate seat 2, air valve suction valve 3 on the air valve core 1 in turn, be equiped with nut 4 in the air valve gate seat 3, be provided with between air valve gate seat 3 and the air valve core 1 seal ring 6 is installed on Sealing 5, the air valve suction valve 3.
In the time of actual the use, air valve gate seat 2 adopts the integral types casting with air valve suction valve 3, has overcome that existing air valve gate seat 2 is threaded with air valve suction valve 3 usefulness and the disalignment defective that produces.Simultaneously,, not only process simple and conveniently, and be convenient to installation and removal because air valve gate seat 2 adopts integrated casting with air valve suction valve 4.
