Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and accompanying drawings, which are not intended to limit the present invention.
Referring to fig. 1 to 6, a novel piston ring for a high-pressure plunger pump of the present invention includes a body 1 and a sealing member 2, wherein the body 1 is provided with a first end portion 11 and a second end portion 12;
the first end 11 comprises a first convex part 111, the first convex part 111 extends towards the second end 12, and the thickness of the first convex part 111 is smaller than that of the body 1;
the second end portion 12 comprises a second convex portion 121, the second convex portion 121 extends towards the first end portion 11, and the thickness of the second convex portion 121 is smaller than that of the body 1;
the first convex part 111 and the second convex part 121 are overlapped, and the sum of the thicknesses of the first convex part 111 and the second convex part 121 is less than or equal to the thickness of the body 1;
the first projection 111 and the second projection 121 are connected to form a connection portion, the seal 2 is attached to the connection portion, and the sum of the length of the first projection 111 and the length of the second projection 121 is smaller than the length of the seal 2.
Specifically, in the present embodiment, the annular body 1 is cut and divided to form two end portions, i.e., a first end portion 11 and a second end portion 12, a first protrusion 111 is formed at the first end portion 11, a second protrusion 121 is formed at the second end portion 12, such that the first protrusion 111 and the second protrusion 121 overlap each other, the overlapping thickness of the first protrusion 111 and the second protrusion 121 is equal to the thickness of the body 1, a closed annular body is formed again, a first diameter is formed, the sealing member 2 is a rubber member and is adhered to the overlapping portion of the first protrusion 111 and the second protrusion 121, the sealing member 2 covers the first end portion 11, the sealing member 2 covers the second end portion 12, the sealing property of the annular body 1 is increased, the piston ring having the first diameter specification is formed, when the outer diameter of the piston ring having the first diameter is reduced due to friction during use, the sealing member 2 is removed, the first protrusion 111 and the second protrusion 121 are overlapped again, and a closed annular body is formed again, and then the sealing element 2 is bonded at the joint to form the piston ring with the second diameter specification, so that the production requirement is met, the service life of the annular body 1 is prolonged, and the production cost is reduced.
Through setting up first convex part 111 and second convex part 121, the overlap joint of the different degree of first convex part 111 and second convex part 121 forms the piston ring of different diameter specifications, improves the life of cyclic annular body 1, realizes reduction in production cost's purpose.
The thickness of the first protrusion 111 is half of the thickness of the body 1, which facilitates the processing and the overlapping with the second protrusion 121.
