Abstract
The utility model relates to a distortion resistant O-shaped sealing ring with a straight edge. The outer contour of the cross section of the sealing ring is formed by the fact that the straight edge and a circular arc line are in butt joint in a head-to-tail mode. The straight edge is contacted with the plane of an installation groove. The length of the straight edge is smaller than the diameter of the sealing ring. A stainless steel spring O-shaped ring is further arranged inside the sealing ring in a surrounding mode. The distortion resistant O-shaped sealing ring with the straight edge has the advantages of being resistant in extrusion, rapid in recovery after distortion, not prone to breakage and capable of preventing a distortion phenomenon of the sealing ring from occurring during a using process, thereby improving reliability of sealing and prolonging the service life of the sealing ring.
Description
[technical field]
The utility model relates to a kind of mechanical assistance accessory, relates in particular to the anti-twist O-ring seals that contains straight flange of a kind of tool.
[background technique]
2012.10.10 disclosed, notification number is that the Chinese utility model patent of CN202484293 discloses a kind of inner liner stainless steel spring O shape circle, it is made up of rubber o-ring and stainless steel spring, is lining in the rubber o-ring in the stainless steel spring.This inner liner stainless steel spring O shape circle has anti-ly to be extruded, is out of shape the back and restore quick, anti-twist and the characteristics of easy-rupturing, good airproof performance, long service life not, can be widely used in as Sealing in the equipment such as oil cylinder, cylinder and pump in fields such as bioengineering, mechanical industry and sewage treatment.Though it has the advantage of simple in structure, standard degree height and highly versatile above-mentioned this pure O-ring seals, but it in use is easy to generate the phenomenon of distortion, during especially for the sealing of axially reciprocating machinery, twisted phenomena is particularly evident, thereby cause the reliability of seal action relatively poor, reach shortening of working life.
[model utility content]
Technical problem to be solved in the utility model is to provide a kind of O-ring seals that contains straight flange, not only have and anti-extrude, be out of shape that restore fast the back, the advantage of easy-rupturing not, can prevent that also the phenomenon of twisting from use appearring in seal ring, and then improve the reliability of its sealing and prolong the life-span of its use.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of anti-twist O-ring seals that contains straight flange, the external frame of sealing ring cross-section is docked respectively by a straight flange and circular arc line head and the tail and forms, described straight flange and mounting groove plane contact, and the length of this straight flange is less than the diameter of seal ring; And stainless steel spring O shape circle is also established in the entity inside of sealing circle.
Further, described straight flange is located at bottom, inboard or the outside of O-ring seals, and described stainless steel spring O shape circle is located at the middle position of sealing circle entity inside.
The beneficial effects of the utility model are: the external frame of sealing ring cross-section has a straight flange, and establish stainless steel spring O shape circle in the entity inside of seal ring, effectively the anti-of lift-off seal circle extruded, restore performance fast after the distortion, it is anti-twist also to be promoted preferably, and easy-rupturing, good airproof performance, long service life are not prolonged preferably.
[description of drawings]
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the utility model seal ring embodiment one a schematic cross-section.
Fig. 2 is the utility model seal ring embodiment two a schematic cross-section.
Fig. 3 is the utility model seal ring embodiment three a schematic cross-section.
[embodiment]
Embodiment one
See also Fig. 1, a kind of O-ring seals that contains straight flange of the utility model, the external frame of sealing ring cross-section is formed by a straight flange 1 and circular arc line 2 head and the tail butt joints, described straight flange 1 and mounting groove 3 plane contact, and the length of this straight flange 1 is less than the diameter of seal ring, and the straight flange 1 in the present embodiment is located at the bottom of O-ring seals; And stainless steel spring O shape circle 4 is also established in sealing circle entity inside, and described stainless steel spring O shape circle 4 is located at the middle position of sealing circle entity inside.
For the purpose of simplifying the description and be convenient to each embodiment's of comparison the utility model different place, in the explanation of following examples, use identical symbol mark for identical assembly, and only describe, and no longer repeat to give unnecessary details existing together mutually at different place.
Embodiment two
See also Fig. 2, unique difference of present embodiment and embodiment one is: the straight flange 1 in the present embodiment is located at the outside of O-ring seals.
Embodiment three
See also Fig. 3, unique difference of present embodiment and embodiment one is: the straight flange 1 in the present embodiment is located at the inboard of O-ring seals.
The utility model is not only simple in structure, cost is lower, and sealing effect is preferable, especially be fit to be applied to the sealing of axially reciprocating machinery, not only have and anti-extrude, be out of shape that restore fast the back, the advantage of easy-rupturing not, can prevent that also the phenomenon of twisting from use appearring in seal ring, and then improve the reliability of its sealing and prolong the life-span of its use.
The manufacture method of the seal ring that the utility model is realized is basic identical with the manufacture method of the O-ring seals of using always, specifically be that rubber or other manufactured materialss are filled in the corresponding mould, again stainless steel spring O shape circle is placed on the correct position of mould, the heating pressurization, vulcanize to finishing by its conditions of vulcanization, take out trimming and get final product.
Claims (3)
1. anti-twist O-ring seals that contains straight flange is characterized in that: the external frame of sealing ring cross-section by a straight flange and circular arc line head and the tail respectively butt joint form described straight flange and mounting groove plane contact, and the length of this straight flange is less than the diameter of seal ring; And stainless steel spring O shape circle is also established in the entity inside of sealing circle.
2. a kind of according to claim 1 anti-twist O-ring seals that contains straight flange is characterized in that: described straight flange is located at bottom, inboard or the outside of O-ring seals, and described stainless steel spring O shape circle is located at the middle position of sealing circle entity inside.
