In a preferred embodiment of the present invention, the material of the anti-corrosive coating is iron red phenolic paint.
In a preferred embodiment of the present invention, the antifriction coating is made of a dry film lubricant.
In a preferred embodiment of the present invention, the cross-section of the primary piston ring is a "concave" structure, and the cross-section of the secondary piston ring is a "T" structure.
In a preferred embodiment of the present invention, the secondary piston ring having a "T" shaped cross-section is inserted into a mating primary piston ring having a "concave" shaped cross-section.
In a preferred embodiment of the present invention, the height of the limiting ring is the same as the depth of the limiting groove.
The utility model has the advantages that: the utility model provides a components of a whole that can function independently piston ring that leakproofness is good falls into main piston ring and vice piston ring with the piston ring, conveniently maintains the change when the piston ring is local to be damaged, utilizes the principle that magnetism opposite sex was inhaled to realize the fixed of main piston ring and vice piston ring to effect when can reaching better sealed, avoided the situation that the piston ring appears leaking when sealed.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
