Abstract
The utility model discloses a metal elastic sealing structure capable of resisting high temperature. The metal elastic sealing structure capable of resisting high temperature comprises a Y-shaped sealing structure main body, wherein the Y-shaped sealing structure main body comprises an inner lip and an outer lip, and an included angle is arranged between the inner lip and the outer lip. The sealing structure has the advantages of simple structure, high reliability and good sealing effect, can be repeatedly disassembled for use and is applicable to sealing lubricating oil of a thermal end component at a temperature of more than 100 DEG C.
Description
Technical field
The utility model relates to a kind of sealing configuration, especially relates to a kind of resistant to elevated temperatures metal elastic-sealed structure, belongs to the liquid seal field.
Background technique
Because between parts, often need to use seal arrangement, seal form is varied on the market at present, be used for hundreds of degree hot-end components seal structure complex, cost is high and be unfavorable for dismantling repeatedly.Increase labor intensity of operating personnel, reduced manufacturing efficiency.Traditional seal arrangement fecund industry rubber material is processed, on the market for simple in structure, reliability is high, the elevated-temperature seal topology requirement amount that can dismantle use repeatedly heightens.
The model utility content
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned existing technology; A kind of resistant to elevated temperatures metal elastic-sealed structure is provided; The sealing structure simple in structure, reliability is high, can dismantle use repeatedly, favorable sealing effect can be useful in the lubricating oil sealing of hundreds of degree hot-end components.
The purpose of the utility model realizes through following technical proposals: a kind of resistant to elevated temperatures metal elastic-sealed structure, comprise Y type sealing configuration body, and said Y type sealing configuration body comprises epipharynx and outer lip, is provided with angle between said epipharynx and the outer lip.
Said epipharynx and outer lip all are arranged on the same end face of Y type sealing configuration body, and the height of said epipharynx and outer lip is identical.
Be 30～38 ° angle between the inwall of said epipharynx and the inwall of outer lip.
Be 33 ° angle between the inwall of said epipharynx and the inwall of outer lip.
The outer wall of said epipharynx and the outer wall of outer lip are 50～58 ° angle.
The outer wall of said epipharynx and the outer wall of outer lip are 55 ° angle.
Said Y type sealing configuration body adopts spring steel to process.
In sum, the beneficial effect of the utility model is: the sealing structure simple in structure, reliability is high, can dismantle use repeatedly, favorable sealing effect can be useful in the lubricating oil sealing of hundreds of degree hot-end components.
Description of drawings
The installment state schematic representation of Fig. 1 the utility model;
Fig. 2 is the cross section structure schematic representation of the utility model;
Fig. 3 is the plan view of the utility model.
The mark of part in the accompanying drawing: 1---parts one; 2---parts two; 3---Y type sealing configuration body; 4---epipharynx; 5---outer lip.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the mode of execution of the utility model is not limited only to this.
Embodiment:
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of resistant to elevated temperatures metal elastic-sealed structure comprises Y type sealing configuration body 3, and said Y type sealing configuration body 3 comprises epipharynx 4 and outer lip 5, is provided with angle between said epipharynx 4 and the outer lip 5.Realize that elevated-temperature seal is made up of Y type sealing configuration body 3 and two sealing surfaces and accomplishes; The mounting point is a rectangular sealing cavity that is made up of the continuous face of transferring in the right angle of parts 1 and parts 22; The width of sealing cavity is more smaller than the width in Y type sealing configuration body 3 cross sections; During installation the sealed section axial direction is formed extruding, thereby make the shape metallic leak-proof structure body be close to two sealing surfaces, reach the purpose of sealing; The sealing structure is used for the lubricating oil sealing of hundreds of degree hot-end components, can dismantle repeatedly.
Said epipharynx 4 all is arranged on the same end face of Y type sealing configuration body 3 with outer lip 5, and said epipharynx 4 is identical with the height of outer lip 5.Because its cross section is
YType, the cross-sectional dimension structure of epipharynx 4 and outer lip 5 is all consistent, has guaranteed the seal process stress equalization,
Y The epipharynx 4 in type cross section and the limit, outer of outer lip 5 are sharp edge, the back sharp edge is installed is adjacent to sealing surface.
Be 30～38 ° angle between the inwall of the inwall of said epipharynx 4 and outer lip 5.Different angles is different on the effect of sealing, selects only angle according to different environment.
Be 33 ° angle between the inwall of the inwall of said epipharynx 4 and outer lip 5.According to the sealing configuration properties of materials, be 33 ° angle between the inwall of the inwall of epipharynx 4 and outer lip 5, can make the effect of sealing reach best, simultaneously stressed also the most balanced.
The outer wall of the outer wall of said epipharynx 4 and outer lip 5 is 50～58 ° angle.Different angles is different on the effect of sealing, selects only angle according to different environment.
The outer wall of the outer wall of said epipharynx 4 and outer lip 5 is 55 ° angle.According to sealing configuration properties of materials gained, the outer wall of the outer wall of epipharynx 4 and outer lip 5 is 55 ° angle, can make the effect of sealing reach best.
Said Y type sealing configuration body 3 adopts spring steel to process.Traditional seal ring adopts rubber to process, and when being used for slipper seal, utilizes the expansion function of rubber to realize sealing, still under the condition of high temperature, is prone to take place phenomenons such as thawing, can't sealing effect.The employing spring steel is made, and can bear high temperature, is applied to fixing seal, makes eyelet be close to sealing surface through side pressure, thus the sealing function under the condition that reaches a high temperature.
Take aforesaid way, just can realize the utility model preferably.
