Abstract

The utility model relates to a sealing ring with openings. The sealing ring comprises an annular base (1), an annular step surface (2) and the sealing ring (5), wherein the annular base (1) and the annular step surface (2) are an integrally formed structure, and provided with the openings (3) in the radial direction, an annular groove (6) is formed in the inner wall of the annular base (1), and the sealing ring (5) is filled in the annular groove (6). The sealing ring disclosed by the utility model has the benefits that the annular groove is formed in the inner wall of the annular base, and the sealing ring is filled in the annular groove, so that the sealing ring is matched with a main shaft to facilitate better sealing performance; anti-rotating grooves are formed in the top surface of the annular step surface, and in a use process, the wear rate is lowered, so that the service life is greatly prolonged; the openings are formed in the annular base and the annular step surface along the radial direction, and the annular base is extruded during a mounting process, so that the openings are shrunk, and the mounting is more convenient and simpler, and the sealing effect is not affected.

Description

A kind of seal ring with opening
skill technical field
The utility model relates to a kind of seal ring, particularly a kind of seal ring with opening.
Background technique
Seal ring in the course of the work, except bearing the factors such as working temperature, pressure, corrosion, also need the friction pair end face friction of bearing due to seal ring to produce certain temperature simultaneously, thereby aggravated the wearing and tearing of the friction pair end face of seal ring, and then affected sealing effect and the working life of seal ring.
In mechanical system, seal arrangement is very important constituent element, under many circumstances, sealability will directly affect service behaviour and the quality of whole system, seal ring is generally used on the junction surface of the link of establishing stream in two, when seal ring is installed, need to be by seal ring inlay card in the adjacent groove that needs sealed connection part, then by bolt etc., two parts are connected, the sealing that keeps two links by seal ring, but such seal ring is easy to drop out when internal high pressure, and easily dislocation when mounted, cause sealing influenced, also may the internal flow path of link be formed and be disturbed simultaneously, give to install and use and bring very big inconvenience.
The inertia of existing seal ring oil ring when work is large, energy consumption is larger, the rate of wear is fast, and particularly existing seal ring opening is mostly flat design, and after long-time use, the opening at two ends can wear and tear and make the defective tightness of fitting, be easy to occur gas leak phenomenon, cause equipment to use.
Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of good seal performance, long service life and the seal ring with opening convenient for installation and maintenance are provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of seal ring with opening, it comprises annular base, annular table terrace and seal ring, described annular base and the annular table terrace structure that is formed in one, annular base and annular table terrace radially offer opening, on the inwall of annular base, offer annular groove, seal ring fills in annular groove.
Described opening has at least one rectangle step.
On the end face of described annular table terrace, also offer anti-rotation groove.
Described anti-rotation groove has 2~4.
The utlity model has following advantage:
1, on the inwall of annular base, offer annular groove, and in the in-built packing seal of annular groove, seal ring coordinates with main shaft, be difficult for gas leak phenomenon occurs, sealability is better.
2, on the end face of annular table terrace, anti-rotation groove is set, in use, reduces the rate of wear, increase substantially working life.
3, at annular base and annular table terrace, radially offer opening, when mounted, extruding annular base, shrinks opening, easier for installation simple, and can not affect sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional structure schematic diagram in Fig. 1;
In figure: 1-annular base, 2-annular table terrace, 3-opening, 4-anti-rotation groove, 5-seal ring, 6-annular groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As depicted in figs. 1 and 2, a kind of seal ring with opening, it comprises annular base 1, annular table terrace 2 and seal ring 5, described annular base 1 and annular table terrace 2 structure that is formed in one, annular base 1 radially offers opening 3 with annular table terrace 2, on the inwall of annular base 1, offer annular groove 6, seal ring 5 fills in annular groove 6.
Further, described opening 3 has at least one rectangle step.
Further, on the end face of described annular table terrace 2, also offer anti-rotation groove 4.
Further, described anti-rotation groove 4 has 2~4.
When mounted, extruding annular base 1, shrinks opening 3, annular base 1 distortion, and diameter diminishes a little, reduces installation difficulty, is convenient to when safeguarding more quick and easy.
Seal ring adopts Hardmetal materials to make, and its resistance to flexure is not less than 1500N/mm 2.
