Abstract
A kind of Novel sealing ring, relate to sealing configuration, it comprise the first seal ring and with the first seal ring with the use of the second seal ring, the first described seal ring comprises the first circle body, first circle body cross section is the isosceles triangle having unfilled corner, the unfilled corner of isosceles triangle is positioned at the base angle of the outer side of the first circle body, leg-of-mutton drift angle is provided with arc transition, described arc transition is semi-circular arc, the second described seal ring comprises the second circle body, the upper-end surface of the second circle body is provided with the annular groove with first lap mates, the cross section of annular groove is V-type, the length of the inner side edge of V-type is greater than the length of outer side, the first described seal ring and the material of the second seal ring are polyurethane synthetic material.The utility model has the feature of good sealing effect, long service life.
Description
Technical field
The utility model relates to sealing configuration, is a kind of Novel sealing ring specifically.
Background technique
Seal ring using scope is wide, be widely used in the mechanical seal of every profession and trade, the working life of existing seal ring is short, the situation of seal failure especially corrosive atmosphere application is easily occurred to, and the seal ring that common two-piece combines, because structural design is unreasonable, the two-piece concentricity of seal ring is bad, overall unstable, cause stressed between part and part and wear and tear uneven, not having effect and the effect of monolithic stability.Grown service time, the effect of the flexibility decrease impact sealing of seal ring simultaneously.
Model utility content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of Novel sealing ring, and it has the feature of good sealing effect, long service life.
In order to solve the problem, the utility model is by the following technical solutions: a kind of Novel sealing ring, it is characterized in that, comprise the first seal ring and with the first seal ring with the use of the second seal ring, the first described seal ring comprises the first circle body, first circle body cross section is the isosceles triangle having unfilled corner, the unfilled corner of isosceles triangle is positioned at the base angle of the outer side of the first circle body, leg-of-mutton drift angle is provided with arc transition, described arc transition is semi-circular arc, the second described seal ring comprises the second circle body, the upper-end surface of the second circle body is provided with the annular groove with first lap mates, the cross section of annular groove is V-type, the length of the inner side edge of V-type is greater than the length of outer side, the first described seal ring and the material of the second seal ring are polyurethane synthetic material.
The beneficial effects of the utility model are:
1, the application of polyurethane synthetic material and the design of its structural type make that it is more wear-resisting, corrosion-resistant, shock resistance, long service life.
The cross section of 2, described annular groove is V-type, the length of the inner side edge of V-type is greater than the length of outer side, due to seal ring inner ring and the tactile phase mutual friction that is coupling, makes the thickness inside it be greater than the thickness in outside like this, enhance its wear resistance, improve working life.
3, leg-of-mutton drift angle is provided with arc transition, described arc transition is semi-circular arc, gap is there is between the annular groove of arc transition and the second circle body, can shock absorbing, when after the first seal ring and the second ring wear, the existence due to gap makes the arc transition of the first seal ring to enter in gap, thus increases the amplitude of the spreading of the second seal ring, ensure good sealing effect, thus improve its working life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the structural representation of using state of the present utility model;
Fig. 2 is the plan view of the first seal ring of the present utility model;
Fig. 3 is the plan view of the second seal ring of the present utility model;
In figure: 1 first circle body, 12 arc transition, 13 unfilled corners, 2 second circle bodies, 21 annular grooves.
Embodiment
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of Novel sealing ring, comprise the first seal ring and with the first seal ring with the use of the second seal ring, the first described seal ring comprises the first circle body 1, first circle body 1 cross section is the isosceles triangle having unfilled corner 13, the unfilled corner 13 of isosceles triangle is positioned at the base angle of the outer side of the first circle body 1, leg-of-mutton drift angle is provided with arc transition 12, described arc transition 12 is semi-circular arc, the second described seal ring comprises the second circle body 2, the upper-end surface of the second circle body 2 is provided with the annular groove 21 matched with the first circle body 1, the cross section of annular groove 21 is V-type, the length of the inner side edge of V-type is greater than the length of outer side, the first described seal ring and the material of the second seal ring are polyurethane synthetic material.
The utility model is not only confined to above-described embodiment.
