Abstract
The invention relates to a regulating valve with high corrosion resistance for a vent pipe and belongs to the technical field of automotive vent-pipes. The regulating valve comprises a valve seat and a regulating bar, wherein the valve seat is provided with two cavities with different opening diameters; the regulating bar penetrates the area between the two cavities of the valve seat; the two ends of the regulating bar are sealed with the valve seat by seal rings; a twisting pipe with a round cross section is arranged at one end part of the regulating bar. The regulating valve with high corrosion resistance for the vent pipe is simple and reasonable in structural design, and simple and convenient to adjust. As the valve seat is subjected to corrosion-resistant treatment, the corrosion resistance of the regulating valve is remarkably improved.
Description
Technical field
The present invention relates to the blast pipe control valve that a kind of corrosion resistance is strong, belong to automobile exhaust pipe technical field.
Background technology
The blast pipe control valve that existing corrosion resistance is strong, structure is comparatively complicated, and manufacturing cost is high. And the corrosion resistance of valve seat is very poor, service life is very short.
Summary of the invention
For the technical problem existing in prior art, the invention provides the blast pipe control valve that the simple corrosion resistance of a kind of structural design is strong.
To achieve these goals, the technical scheme of employing is as follows:
The blast pipe control valve that a kind of corrosion resistance is strong, comprise valve seat and adjusting rod, valve seat is provided with the cavity that two opening diameters differ, the region of adjusting rod through two cavitys of valve seat, the two ends of adjusting rod by sealing ring make itself and valve base sealing, the end of adjusting rod have cross section rounded turn pipe.
Described valve seat forms protecting film by anti-corrosion treatment on its surface, and processing technology is:
Step 1., on valve seat, brush anticorrosion basal liquid, anticorrosion basal liquid is mixed by 20 parts of polyvinyl acetate emulsions, 12 parts of diethanol amine, 10 parts of glycerine, 2 parts of watery hydrochloric acid, 0.5 part of anthocyanin, 10 parts of potash and 85 parts of water;
Step 2., adopt Implantation mode to inject basic zirconium phosphate, silica, chromic acid chromium and the prodan insoluble network layer altogether that to form thickness be 80nm at valve base surface;
Step 3., form metal oxide layer again on insoluble altogether network layer;
Step is coated with the priming paint that thickness is 100nm 4., again on metal oxide layer.
The blast pipe control valve that corrosion resistance of the present invention is strong, structural design is simple, reasonable, regulates easy. In addition, by anti-corrosion treatment valve seat, its decay resistance is significantly improved.
Brief description of the drawings
For the ease of it will be appreciated by those skilled in the art that the present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Refer to Fig. 1, the blast pipe control valve that a kind of corrosion resistance is strong, there is valve seat and adjusting rod 2, valve seat is provided with cavity 3 and the cavity 6 that two opening diameters differ, the region of adjusting rod 2 through two cavitys of valve seat, the two ends of adjusting rod 2 by sealing ring 5 and sealing ring 4 make itself and valve base sealing, the end of adjusting rod 2 have cross section rounded turn pipe 1, the outer surface that turns pipe 1 is continuous wavy shaped configuration.
Described valve seat forms protecting film by anti-corrosion treatment on its surface, and processing technology is:
Step 1., on valve seat, brush anticorrosion basal liquid, anticorrosion basal liquid is mixed by 20 parts of polyvinyl acetate emulsions, 12 parts of diethanol amine, 10 parts of glycerine, 2 parts of watery hydrochloric acid, 0.5 part of anthocyanin, 10 parts of potash and 85 parts of water;
Step 2., adopt Implantation mode to inject basic zirconium phosphate, silica, chromic acid chromium and the prodan insoluble network layer altogether that to form thickness be 80nm at valve base surface;
Step 3., form metal oxide layer again on insoluble altogether network layer;
Step is coated with the priming paint that thickness is 100nm 4., again on metal oxide layer.
Above content is only to structure example of the present invention and explanation; affiliated those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of invention or surmount this scope as defined in the claims, all should belong to protection scope of the present invention.
