Abstract
The utility model discloses a spray gun feeding structure's check valve, include the disk seat and install in the case of disk seat, the case include ceramic valve core case and with ceramic valve core case complex porcelain bead, the passageway is established to ceramic valve core case, has spring and porcelain bead to offset and makes porcelain bead seal the passageway export of ceramic valve core case. The pottery valve core case has good abrasion resistance with porcelain bead's cooperation, even high -speed flow of polish also can not be to its life who produces wearing and tearing, extension check valve that consequently can be great.
Description
Technical field
The utility model is related to a kind of valve body of spray gun.
Background technology
In addition to using polishing wheel, some workpiece also need to add polishing fluid glossing.In order to can be equal by polishing fluid
Even is sprayed to burnishing surface, it is therefore desirable to use spray gun, and existing gun design, especially check valve are usually to be matched somebody with somebody using metal
Part etc. makes.But due to being dispersed with abrasive in polishing fluid, when polishing fluid high speed is in unidirectional valve flow, abrasive can be to it
Abrasion is produced, so the sandblasting that existing spray gun is used to polish also easily into the situation of check valve damage occurs.
The content of the invention
The purpose of this utility model is just to provide a kind of check valve of spray gun feeding structure to be caused with solving check valve abrasion
The problem of damage.
The utility model is realized in that above-mentioned purpose：
The check valve of spray gun feeding structure, including valve seat and the valve element of valve seat is installed on, the valve element includes ceramic valve
Core print seat and the porcelain bead coordinated with ceramic valve core print seat, ceramic valve core print seat set passage, have spring to be offseted with porcelain bead and close porcelain bead
The channel outlet of ceramic valve core print seat.
Wherein, the valve element is connected with valve seat by screw thread and ceramic valve core print seat is locked in valve seat.
The beneficial effects of the utility model are：Ceramic valve core print seat has good abrasion resistance with the cooperation of porcelain bead, even if
Polishing fluid flow at high speed will not also produce abrasion to it, therefore, it is possible to greatly extend the service life of check valve.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
Fig. 1 is cross section view of the present utility model.
Specific embodiment
Reference picture 1, the check valve of spray gun feeding structure, including valve seat 1 and the valve element of valve seat 1 is installed on, the valve element
The porcelain bead 3 coordinated including ceramic valve core print seat 2 and with ceramic valve core print seat 2, ceramic valve core print seat 2 sets passage, there is spring 4 and porcelain bead 3
Offset and make porcelain bead 3 to close the channel outlet of ceramic valve core print seat 2.The cooperation of ceramic valve core print seat 2 and porcelain bead 3 is with good wear-resistant
Performance, even if polishing fluid flow at high speed will not also produce abrasion to it, therefore, it is possible to greatly extend the service life of check valve.
For the ease of the installation and replacing of ceramic cartridge and porcelain bead 3, the valve element is connected simultaneously by screw thread with valve seat 1
Ceramic valve core print seat 2 is locked in valve seat 1.
