Abstract
The utility model relates to a sealing ring used for the soft packing of the reciprocating movement of axial type, which is characterized in that a sealing ring body (1) is provided with a taper cut (2), and an angle alpha between the taper cut (2) and one side face of the sealing ring body (1) is more than 0 DEG and less than 90 DEG or more than 90 DEG and less than 180 DEG, which causes the sealing ring body (1) to be in off state. The utility model has the advantages of simple structure, convenient assembly and disassembly, reliable sealing, prolongable service life, light regulation of axial pressure, protection of casings and long service life. Assembly and disassembly are reduced so as to reduce the cost.
Description
Technical field: the utility model relates to a kind of seal ring, especially a kind of class to-and-fro motion soft packing seal circle that is used for.
Background technique: an existing axle class to-and-fro motion soft packing seal circle type has " O " RunddichtringO, rectangular seal, lip-type seal circle, combined seal ring etc., utilizes axial compression soft packing seal circle, makes it produce radial elastic distortion, filling gap and sealing.When compressing the soft packing seal circle, because the elastoplasticity of soft packing seal circle self, make Organizational Structure under the effect of external force, produce distortion and molecular distortion slippage and reach the purpose of clogging the gap, therefore in using journey, impacting force is constantly adjusted in the wearing and tearing that form along with to-and-fro motion, makes the very fast disappearance of elasticity of soft packing, thereby it is very fast that seal ring was lost efficacy.
The model utility content:
The technical problems to be solved in the utility model is: at above-mentioned prior art deficiency, provide a kind of sealing more reliable, prolong the seal ring technology in working life significantly.
The technical scheme in the invention for solving the above technical problem is: be shaped on angular cut in sealing on the circle body, and the angle a between the side of angular cut and sealing circle body is: 0 °＜a＜90 ° or 90 °＜a＜180 ° make that sealing circle body is off state.
The utility model beneficial effect compared with prior art:
1, simple in structure, mounting or dismounting are convenient;
2, sealing is reliable, can increase the service life;
3, the adjustment of axial pressure is light, the protection body;
4, long service life has reduced user cost thereby reduce mounting or dismounting.
Description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a plan view of the present utility model.
Describe a most preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, be shaped on angular cut 2 on the circle body 1 in sealing, and between the side of angular cut 2 and sealing circle body 1 angle a=60 °, make that sealing circle body 1 is off state.
Sealing circle body 1 cross section of the present utility model can be rectangle, circle, lip type or is one of other arbitrary shape.
Working principle:
Soft packing seal circle of the present utility model is under the effect of axial force, the packing seal circle is not only from producing distortion and molecule slippage in the power effect, simultaneously owing on the seal ring angular cut is arranged, under otch, produce slippage,, force filler to be out of shape to internal diameter because the external diameter direction has the restriction of Stuffing box, thereby reach the gap of clogging more easily between axle journal and the seal ring, make sealing more reliable, prolonged the life-span of seal ring significantly, reduced user cost.
Claims (2)
1, a kind of cut sealing circle, containing sealing circle body (1) forms, it is characterized in that: on sealing circle body (1), be shaped on angular cut (2), and the angle a between the side of angular cut (2) and sealing circle body (1) is: 0 °＜a＜90 ° or 90 °＜a＜180 ° make the ring body of sealing circle body (1) be off state.
2, a kind of cut sealing circle according to claim 1 is characterized in that: the cross section of sealing circle body (1) is rectangle, circle, lip type or is one of other arbitrary shape.
