Abstract
The invention discloses a novel sealing ring made of high polymer materials. The novel sealing ring made of the high polymer materials comprises a ring body consisting of a reinforcing ring, a PEEK (poly ether ether ketone) ring and a positioning ring, each of the reinforcing ring and the positioning ring is a rubber elastic body, square positioning grooves are formed on the inner side of the positioning ring, and connecting grooves are formed at the joint of the reinforcing ring and the PEEK ring as well as at the joint of the PEEK ring and the positioning ring and are trapezoidal grooves. The novel sealing ring made of the high polymer materials has the advantages that corrosion resistance, high-temperature resistance, abrasive resistance, heat stability and the like of the sealing ring can be improved greatly by the aid of a structure consisting of the reinforcing ring, the PEEK ring and the positioning ring; the square grooves formed in the positioning ring can position the ring body effectively, and accordingly the novel sealing ring is convenient to use; and the sealing ring is convenient and simple to assemble by the aid of the connecting grooves, and each portion of the sealing ring can be reused by the aid of the detachable structure, so that production cost can be greatly saved for enterprises.
Description
Technical field
The present invention relates to a kind of Sealing, particularly a kind of novel high polymer material seal ring.
Background technique
Seal ring is the main Sealing of swivel joint, bears pressure medium and running shaft (outer tube), housing friction during operation, the working life of factor appreciable impact seal rings such as temperature, rotating speed and medium.At present the conventional seals ring that uses mostly is metallic packing ring greatly, and shortcomings such as working life is short, easy to wear are arranged in use,
Summary of the invention
The objective of the invention is provides a kind of novel high polymer material seal ring in order to overcome above deficiency, improves compression resistance and the working life of seal ring.
Purpose of the present invention realizes like this:
A kind of novel high polymer material seal ring of the present invention comprises ring body, and wherein, described ring body is by stiffening ring, and PEEK encircles, and positioning ring is formed; Described stiffening ring is for being rubber elastomer with positioning ring; Described PEEK ring constitutes for high molecular polyether ether resin of copper material.
Above-mentioned a kind of novel high polymer material seal ring, wherein, described stiffening ring is processed by acrylate rubber.
Above-mentioned a kind of novel high polymer material seal ring, wherein, described positioning ring is processed by nitrile rubber.
Above-mentioned a kind of novel high polymer material seal ring, wherein, described positioning ring inboard is provided with the location square groove.
Above-mentioned a kind of novel high polymer material seal ring, wherein, described stiffening ring, PEEK ring, the positioning ring joint is provided with connecting groove.
Above-mentioned a kind of novel high polymer material seal ring, wherein, described stiffening ring, PEEK ring, positioning ring joint connecting groove is trapezoidal groove.
Compared with prior art, the present invention has the following advantages:
1) stiffening ring is set, utilizes the peculiar elastic compensating ability of rubber elastomer, improve the seal ring seal performance.
2) high molecular polyether ether resin of copper has advantages such as excellent model-performance, excellent self-lubrication, corrosion resistance, heat-resisting quantity, wear resistance, thermostability, can effectively improve usability and the using effect of seal ring.
3) the positioning ring inboard is provided with the location square groove, can be effectively with the ring body location, and convenient the use.
4) stiffening ring, PEEK ring, the positioning ring joint is provided with connecting groove, uses connecting groove to connect, and outer shroud or interior ring can conveniently be replaced after using wearing and tearing, and the PEEK ring is reusable, saves cost.
A kind of novel high polymer material seal ring of the present invention, by stiffening ring, PEEK ring, locating ring structure can improve the performances such as corrosion resistance, heat-resisting quantity, wear resistance, thermostability of seal ring greatly.Be provided with square groove in the positioning ring, can be effectively with the ring body location, the convenient use.The connecting groove setting can make seal ring easy to assembly succinct, and splits structure and make that various piece can be recycling, can save enterprise's cost of production greatly.
Description of drawings
Fig. 1 is sectional view of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in the figure, a kind of novel high polymer material seal ring of the present invention comprises ring body, and wherein, described ring body is by stiffening ring 1, and PEEK encircles 2, and positioning ring 3 is formed; Described stiffening ring 1 is for being rubber elastomer with positioning ring 3; Described PEEK ring 2 is that high molecular polyether ether resin of copper material constitutes; Described stiffening ring 1 is processed by acrylate rubber; Described positioning ring 3 is processed by nitrile rubber; Described positioning ring 3 inboards are provided with location square groove 4; Described stiffening ring 1, PEEK ring 2, positioning ring 3 joints are provided with connecting groove 5; Described stiffening ring 1, PEEK ring 2, positioning ring 3 joint connecting grooves 5 are trapezoidal groove.
