Abstract
A metal rubber sealing ring relates to a sealing component. The sealing performance of the existing rubber sealing component is not satisfied in the working conditions of high temperature, low temperature, big temperature difference, cankerous medium and long service life due to the intrinsic characteristics of the materials, the utility model comprises a ring elastic component (1), the outer of the ring elastic component (1) is covered with an outer wrapping skin (2), the cross-section of the ring elastic component (1) has a well-regulated shape, the outer wrapping skin (2) is provided with a gap (2-1). The innovation of the utility model structure results in the innovation of the performance, the organic combination of the elastic component and the elastic outer wrapping skin enables the sealing ring has the ability of enduring the axial loads and the radial loads, the sealing performances of the sealing ring along two directions are ensured; the sealing reliability and the working stability are ensured in the operation, the utility model is the ideal substitute of the ordinary rubber sealing ring.
Description
Technical field: the utility model relates to a kind of sealing component.
Background technique: in mechanical system, seal arrangement is a very important constituent element, and under many circumstances, sealability will directly influence whole system operation performance and quality, and poor sealing will cause systemic-function to descend, even accidents caused.In recent years, the research of sealing technique and seal arrangement has had significant progress, the structure shape and the performance quality of Sealing have had large increase, in numerous seal form, with rubber is that raw-material various Sealing occupies very big ratio in actual application in engineering, but rubber seal is limit owing to its material inherent characteristic, at high temperature, low temperature, the big temperature difference, under the operating mode such as aggressive medium and long lifetime, its sealability is difficult to satisfactory, the R and D that are operated in the dedicated sealing member under these extraordinary operating modes are one of major subjects of mechanical engineering field always, therefore, developing the novel seal member is very necessary with the demand that satisfies these special operation conditions.
The model utility content: the purpose of this utility model is to provide a kind of and does not contain General Purpose Rubber but have than the better metal-rubber seal ring of General Purpose Rubber seal ring performance.
The metal-rubber seal ring comprises annular elastic element 1, in the coated outside of elastic element 1 exoperidium 2 is arranged, and the cross section of described elastic element 1 has the shape of rule, has breach 2-1 on the described exoperidium 2.
The utlity model has the better elastic performance, compare with the General Purpose Rubber sealing component, the metal-rubber seal ring has high temperature resistant, low temperature resistant, the anti-big temperature difference, characteristics such as anticorrosive, aging; Metal-rubber seal ring sectional shape can be prepared into circle, ellipse, square, rectangle or trapezoidal etc. according to different operating mode demands, its exoperidium opening direction can be on internal diameter, external diameter or upper and lower surface, therefore, the metal-rubber seal ring can either be realized the sealing with elastic element parallel axes direction, can realize having adaptability very widely again along elastic element sealing radially; Select the suitable opening direction, to help improving the sealability of seal ring, its principle is as follows: sealing medium can enter into the metal-rubber elastic element by the opening of foreskin, because the metal-rubber elastic element has porosity, when medium is full of, will produce active force to foreskin, further the working pressure between raising and the sealed member surface of contact, thereby raising sealing, these characteristics are the distinctive performances of metal-rubber seal ring; The innovation of the utility model seal ring structure has caused the innovation on the performance, and the organic assembling of elastic element and elasticity exoperidium makes seal ring have the ability of thrust load of bearing and radial load, has guaranteed the sealability of seal ring along both direction; Change material, sectional dimension, the pre compressed magnitude of elastic element, can make seal ring have different sealabilities, help forming series product, satisfy the needs of different operating modes; The sealing ring can be used for the inoperable environment of General Purpose Rubber, is particularly suitable for the sealing of extraordinary operating modes such as Aero-Space; The sealing ring is made the cross section for circular, oval, square, rectangle or structure shape such as trapezoidal, satisfy of the requirement of the installation place of seal ring, realize different sealabilities simultaneously seal ring structure.The sealability of the utility model seal ring is better than the sealability of General Purpose Rubber seal ring, can guarantee the reliability that seals and the stability of work in the course of the work, is the ideal substitute of rubber seal ring under the extraordinary operating mode.
Description of drawings: Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 are that the cross section is the structural representation of difformity elastic element 1, Fig. 6 is the structural representation of embodiment two, Fig. 7 is the structural representation of embodiment three, Fig. 8 is the structural representation of embodiment four, Fig. 9 is the structural representation of embodiment five, and Figure 10 is the structural representation of embodiment six.
Embodiment one: present embodiment comprises annular elastic element 1, coated outside at elastic element 1 has exoperidium 2, the cross section of described elastic element 1 has the shape of rule, have breach 2-1 on the described exoperidium 2, when the metal-rubber element is installed in the foreskin, guarantee that the metal rubber element has certain pre compressed magnitude, to guarantee the contact pressure between seal ring and the extraneous seal casinghousing.
Embodiment two: with reference to Fig. 1, Fig. 6, the cross section of elastic element 1 is circular in the present embodiment, and exoperidium 2 is wrapped in elastic element 1, and breach 2-1 is arranged on the internal diameter of exoperidium 2.
Embodiment three: with reference to Fig. 2 and Fig. 7, the cross section of elastic element 1 is oval in the present embodiment, and breach 2-1 is arranged on the upper end of exoperidium 2.
Embodiment four: with reference to Fig. 3, Fig. 8, the cross section of elastic element 1 is square in the present embodiment, and breach 2-1 is arranged on the upper end of exoperidium 2.
Embodiment five: with reference to Fig. 4, Fig. 9, the cross section of elastic element 1 is a rectangle in the present embodiment, and breach 2-1 is arranged on the external diameter of exoperidium 2.
Embodiment six: with reference to Fig. 5, Figure 10, the cross section of elastic element 1 is trapezoidal in the present embodiment, and breach 2-1 is arranged on the external diameter of exoperidium 2.
The utility model is applicable to the sealing under the extraordinary operating modes such as Aero-Space, national defence, communications and transportation, light industry and the contour temperature of various civilian machineries, low temperature, the big temperature difference, corrosive environment, impulsive load, space radiation effect, is the ideal substitute of General Purpose Rubber seal ring under the extraordinary operating mode.
