Abstract
A kind of triangle convex ring for sealing circle is provided, there is sealing circle body, described sealing circle body is O type ring structure, the sectional shape of described sealing circle body is E font, the inner side surface of described sealing circle body is dimpling arc surface, symmetrically on two working surfaces up and down of described sealing circle body be shaped with the different triangle bulge loop of multiple diameter, described triangle bulge loop and sealing circle body are formed in one structure.The utility model adopts symmetry on two working surfaces up and down of O RunddichtringO body to be shaped with the different triangle bulge loop of multiple diameter, when the sealing surface of valve components is by the sealing of flange fastening force, triangle bulge loop on seal ring working surface and valve components sealing surface form multilayer and combine closely, thus play the effects such as good sealing effect, dust-proof and flange fastening force be little.
Description
Technical field
The utility model belongs to Sealing manufacturing technology field, is specifically related to a kind of triangle convex ring for sealing circle.
Background technique
Sealing is that anti-fluid, gas or solid particle leak between adjacent junction plane, and prevent introduced contaminants such as dust and moisture etc. from invading the component of machinery equipment inside, it is the vitals preventing and reduce environmental pollution, be widely used in the national economy main industries such as national defence, chemical industry, oil, coal, communications and transportation and machine-building, the functional reliability of Sealing and working life are the important indicators weighing hydraulic system quality.Now the production of China's sealing article and quality progress into a new stage, but these also far can not meet the needs of development to sealing article of all industries, such as valve, because valve is the direction controlling fluid in fluid system, pressure, the device of flow, it is the device making the media flow in pipe arrangement and equipment or stop also controlling its flow, so the sealability of valve is one of leading indicator of valve mass quality, particularly large-scale for some, when the end face seal of relatively large valve components connects, not only require valve both sides end face seal effective, dust-proof, anti-leak, but also require that connecting end surface flange Tightening moment is little, in order to address this problem, be necessary to propose to improve.
Model utility content
The technical problem that the utility model solves: a kind of triangle convex ring for sealing circle is provided, symmetry on two working surfaces up and down of O RunddichtringO body is adopted to be shaped with the different triangle bulge loop of multiple diameter, when the sealing surface of valve components is by the sealing of flange fastening force, triangle bulge loop on seal ring working surface and valve components sealing surface form multilayer and combine closely, thus play the effects such as good sealing effect, dust-proof and flange fastening force be little.
The technical solution adopted in the utility model: triangle convex ring for sealing circle, there is sealing circle body, described sealing circle body is O type ring structure, the sectional shape of described sealing circle body is E font, the inner side surface of described sealing circle body is dimpling arc surface, symmetrically on two working surfaces up and down of described sealing circle body be shaped with the different triangle bulge loop of multiple diameter, described triangle bulge loop and sealing circle body are formed in one structure.
Wherein, two working surfaces up and down of described sealing circle body are all shaped with the different triangle bulge loop of 3 diameters, form 3 astragal type sealings, each triangle bulge loop described is all connected with coaxial and adjacent two the triangle bulge loop roots of sealing circle body, and the cross section of described triangle bulge loop is the equal isosceles triangles in both sides.
Further, described sealing circle body and triangle bulge loop are the integrated elastic sealing configurations be made up of rubber.
The utility model advantage compared with prior art:
1, symmetry on two working surfaces up and down of O RunddichtringO body is adopted to be shaped with the different triangle bulge loop of multiple diameter, form 3 astragal type sealings, when the sealing surface of valve components is by the sealing of flange fastening force, triangle bulge loop on seal ring working surface forms multilayer by plastic deformation and valve components sealing surface and combines closely, thus elimination gap, there is the effects such as good sealing effect, dust-proof and flange fastening force be little;
2, the material of seal ring main body adopts rubber, and densify, not easily leaks working medium, adaptability and good stability, compressibility and recoverability are good, permanent deformation is little, anticorrosive, rebound elasticity good, ageing resistance is good, long service life;
3, cross section adopts E type cross section, easily installs, easily locates during use;
4, the end face seal that the utility model is specially adapted to large-scale, relatively large valve components connects, and the groove only need processing definite shape during use on valve sealing face can install and part sealing surface does not need fine finishing;
5, the utility model sealing is reliable, and structure is simple, compact dimensions, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the I portion enlarged view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing 1-3, embodiment of the present utility model is described.
Triangle convex ring for sealing circle, have sealing circle body 1, described sealing circle body 1 is O type ring structure, and cross section 2 shape of described sealing circle body 1 is E font, adopts E type cross section, easily installs, easily locates during use, the inner side surface of described sealing circle body 1 is dimpling arc surface 4, on two working surfaces up and down of described sealing circle body 1, symmetry is shaped with the different triangle bulge loop 3 of multiple diameter, described triangle bulge loop 3 and sealing circle body 1 are formed in one structure, two working surfaces up and down of described sealing circle body 1 are all shaped with the different triangle bulge loop of 3 diameters and form 3 astragal types sealings, 3, two triangle bulge loop 3 roots that each triangle bulge loop 3 described is all coaxial and adjacent with sealing circle body 1 are connected, the cross section of described triangle bulge loop 3 is the equal isosceles triangles in both sides, symmetry on two working surfaces up and down of O RunddichtringO body is adopted to be shaped with the different triangle bulge loop of multiple diameter, when the sealing surface of valve components is by the sealing of flange fastening force, triangle bulge loop on seal ring working surface forms multilayer by plastic deformation and valve components sealing surface and combines closely, thus elimination gap, there is good sealing effect, the effects such as dust-proof and flange fastening force is little, described sealing circle body 1 and triangle bulge loop 3 are the integrated elastic sealing configurations be made up of rubber, rubber material is closely knit, not easily leak working medium, adaptability and good stability, compressibility and recoverability are good, permanent deformation is little, anticorrosive, rebound elasticity good, ageing resistance is good, long service life.
The end face seal that the utility model is specially adapted to large-scale, relatively large valve components connects, only need process the groove of definite shape on valve junction surface during use, seal ring and groove adaptation are installed, sealing, the effect such as dust-proof can be played by part sealing surface flange is fastening, and part seal face does not need fine finishing, processing cost is low, has sealing reliable, and structure is simple, compact dimensions, advantage easy to use.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalence changes done with content described in the utility model claim, all should be included within the utility model right.
