Abstract
The utility model discloses a pneumatic sealing ring, comprising a framework and a sealing ring, wherein the inner circumferential surface of the sealing ring is provided with two protruded upper and lower sharp corners between which a groove is arranged. The upper sharp corner comprises a first upper slope and a first lower slope which are crossed; the lower sharp corner comprises a a second upper slope and a second lower slope which are crossed; and the first lower slope and the second upper slope are crossed to form the groove. The pneumatic sealing ring provided by the utility model has the advantages of simple structure, low price and good sealing effect.
Description
Technical field:
The pneumatic auxiliary technical field of the utility model relates to a kind of pneumatic reciprocation sealing circle in particular.
Background technique:
The pneumostop circle, be important a kind of in the pneumatic auxiliary, it roughly is divided into two kinds of motive sealing and static seals, required sealing is a static seal between similar cylinder cap and the cylinder barrel, the place that it is used for fixing, and the sealing that is similar between piston rod and the cylinder barrel is called motive sealing, motive sealing is used in rotation, to-and-fro motion position, the static seal ratio is easier to, and is less demanding, and motive sealing then has very high requirement.
Existingly be used for reciprocal pneumostop circle, see accompanying drawing 1, B constitutes by skeleton A seal ring, when in use the inside and outside circle of seal ring its be subjected to gas pressure, expand the back and is formed a sealing surface, be used for sealing, and obtain reasonable sealing effect.But, facts have proved that existing pneumostop circle sealing effect is also bad.
The model utility content:
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of pneumostop circle is provided, its simple in structure, low price, good sealing effect.
Technology solution of the present utility model is as follows:
A kind of pneumostop circle comprises skeleton and seal ring, and the wedge angle up and down of two protrusions is arranged on the described seal ring inner peripheral surface, and is described fluted between the wedge angle up and down.
Described a kind of pneumostop circle, the described wedge angle of going up is made of first ramp, first lower inclined plane that intersect; Described wedge angle down is made of second ramp, second lower inclined plane that intersect; Described first lower inclined plane and second ramp intersect and to have constituted groove.
Described a kind of pneumostop circle, described wedge angle up and down is along the whole extending circumferentially of described seal ring inner peripheral surface.
Described a kind of pneumostop circle, described first ramp and first lower inclined plane intersect the obtuse angle, and the scope at this obtuse angle is between the 100-150 degree; Second ramp and second lower inclined plane intersect the obtuse angle, and the scope at this obtuse angle is between the 100-150 degree.
Described a kind of pneumostop circle, there is the section of seamlessly transitting described first lower inclined plane and the second ramp intersection.
Described a kind of pneumostop circle, the obtuse angle that described first ramp and first lower inclined plane intersect is degree; The obtuse angle that second ramp and second lower inclined plane intersect is 112 degree.
The utility model beneficial effect is:
1) this novel pneumostop circle, it is by being provided with the wedge angle up and down of two protrusions on the inner peripheral surface of seal ring, when in use, wedge angle is under pressure about in the of two, can form two sealing surfaces, such seal ring just is equivalent to two seal rings in usefulness, under the situation of a sealing surface damage therein, by the assurance sealing effect of another sealing surface continuation.
2) two of this novel pneumostop circle inner peripheral surfaces when wedge angle contacts with piston rod up and down surface of contact little, thereby reduced friction factor, improve natural life-span greatly during owing to the reciprocal dynamic seal (packing) of the reduction of friction factor.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of existing pneumostop circle;
Fig. 2 is this novel structural representation;
Fig. 3 is this novel solid figure.
Embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees accompanying drawing 2,3; A kind of pneumostop circle comprises skeleton 1 and seal ring 2, and the wedge angle up and down 201,202 of two protrusions is arranged on described seal ring 2 inner peripheral surfaces, between the described up and down wedge angle 201,202 fluted 203.
The described wedge angle 201 of going up is made of the first ramp 201a, the first lower inclined plane 201b that intersect; Described wedge angle 202 down is made of the second ramp 202a, the second lower inclined plane 202b that intersect; Described first lower inclined plane and second ramp intersect and to have constituted groove 203.
Described wedge angle 201,202 up and down is along the whole extending circumferentially of described seal ring 2 inner peripheral surfaces.
The described first ramp 201a and the first lower inclined plane 201b intersect the obtuse angle, and the scope at this obtuse angle is between the 100-150 degree; The second ramp 202a and the second lower inclined plane 202b intersect the obtuse angle, and the scope at this obtuse angle is between the 100-150 degree.
There is a section of seamlessly transitting 204 the described first lower inclined plane 201b and the second ramp 202a intersection.
The obtuse angle that the described first ramp 201a and the first lower inclined plane 201b intersect is 120 degree; The obtuse angle that the second ramp 202a and the second lower inclined plane 202b intersect is 112 degree.
