Abstract
The utility model relates to an anti-twisty D-shaped seal ring. The outer outline of the cross section of the seal ring is of a D shape which is formed by three straight flanges and an arc-shaped line, wherein the straight flanges and the arc-shaped line are connected end to end, the facing direction of the D shape is consistent with the facing direction of a groove opening of an installation groove, and a stainless steel spring O-shaped ring is further arranged inside the solid of the seal ring in a circular mode. The anti-twisty D-shaped seal ring has the advantages that the phenomenon that the seal ring is damaged by compression, hurt by biting and distorted in the installation use process can be avoided, installation and location are convenient to do, and the seal ring has the anti-extrusion property due to the existence of the stainless steel spring O-shaped ring, and after the seal ring is deformed, the seal ring is speedy to recover and not easily ruptured, sealing property is also better, and then the service life of the seal ring is prolonged.
Description
[technical field]
The utility model relates to a kind of mechanical assistance accessory, relates in particular to a kind of anti-twist D shape seal ring.
[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.The seal ring of above-mentioned this pure O shape, though that it has is simple in structure, the advantage of standard degree height and highly versatile, the situation that occurs crushing in using installation process but it is exposed to outside the mounting groove easily, and be easy to produce the phenomenon that chews, particularly cooperate with the shallow mounting groove of large scale when installing, it is particularly evident to chew phenomenon, in addition, the seal ring of pure O shape not only is difficult for the location, and when using distortion occurs easily and cause long situation in its working life.
[model utility content]
Technical problem to be solved in the utility model is to provide a kind of anti-twist D shape seal ring, not only have and anti-extrude, be out of shape the back and restore quick, anti-twist and the advantage of easy-rupturing not, the phenomenon that can avoid seal ring crushing in installing and using process, to occur, chew and twist also, and be convenient to installing and locating.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of anti-twist D shape seal ring, wherein: the external frame of sealing ring cross-section forms a D shape by three straight flanges and a circular arc line end-to-end, and this D shape towards with the mounting groove notch towards being consistent; And stainless steel spring O shape circle is also established in sealing circle entity inside.
Further, described stainless steel spring O shape circle is located at the middle position of sealing circle entity inside.
Further, incomplete filled rubber or complete filling rubber in the described stainless steel spring O shape circle.
The beneficial effects of the utility model are: the sealing ring cross-section is arranged to D shape, can avoid seal ring in using installation process, to be exposed to outside the mounting groove and cause the situation of crushing, and can prevent to chew the appearance of phenomenon, also be easy to the location during installation, not be prone to distortion during use; In addition, establish stainless steel spring O shape circle in the entity inside of seal ring, effectively the anti-of lift-off seal circle extruded, and restores 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 schematic cross-section of the anti-twist D shape seal ring of the utility model.
[embodiment]
See also Fig. 1, the D shape seal ring that the utility model is anti-twist, the external frame of sealing ring cross-section forms a D shape by a circular arc line 1 and three straight flange end-to-ends, and this D shape towards with mounting groove 10 notches towards being consistent, three straight flanges are respectively straight flange 2, straight flange 3 and straight flange 4.And stainless steel spring O shape circle 5 is also established in sealing circle entity inside, and described stainless steel spring O shape circle 5 can be located at the middle position of this D shape seal ring entity inside.Described stainless steel spring O shape circle 5 interior not exclusively filled rubber or complete filling rubber.
When installing and using, straight flange 4 planes closely are positioned in the mounting groove 10, by the acting in conjunction of straight flange 2, straight flange 3 and straight flange 4, make seal ring in mounting groove 10, well to locate, and can avoid seal ring to be exposed to the situation that mounting groove 10 causes crushing, chews and twists outward; The existence of stainless steel spring O shape circle makes seal ring have more the anti-characteristics of extruding, and restores easy-rupturing fast and not in seal ring distortion back, and sealing is also better, and then has prolonged the working life of seal ring.
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 D shape seal ring, it is characterized in that: the external frame of sealing ring cross-section forms a D shape by three straight flanges and a circular arc line end-to-end, and this D shape towards with the mounting groove notch towards being consistent; And stainless steel spring O shape circle is also established in sealing circle entity inside.
2. a kind of anti-twist D shape seal ring as claimed in claim 1 is characterized in that: described stainless steel spring O shape circle is located at the middle position of sealing circle entity inside.
