Abstract
A kind of hermetically sealed seal ring is provided, there is seal ring main body, described seal ring main body is square structure, the material of described seal ring main body is high/low temperature rubber, described seal ring body interior is provided with oval hermetically sealed inner chamber, sealed gas up for safekeeping in described hermetically sealed inner chamber, described gas is air, and the cross section of described seal ring main body is mainly made up of oval ring, back taper lip and triangle.The utility model is by adopting square structure and profiled-cross-section, and in the hermetically sealed inner chamber of ellipse, seal a certain amount of gas up for safekeeping, constitute one be applicable to relatively large equipment component install and have that good sealing effect, damping property are good, good stability, easily location and installation, the seal ring that not yielding, long service life, structure are simple, easy to use.
Description
Technical field
The utility model belongs to Sealing manufacturing technology field, is specifically related to a kind of hermetically sealed seal ring.
Background technique
Seal ring is of a great variety and be widely used in five metals plastic cement, water supply and drainage, fire-fighting, boats and ships, etc. pipe-line system, Qi Che ﹑ motorcycle, various Ji Xie ﹑ Jia Yong electricity Qi ﹑ electricity ﹑ Yun moves the industries such as Qi Cai ﹑ pneumatic element, there is sealing, grease proofing, waterproof, anticorrosion, anti-leak, reduce to rub between part, anticorrosive, the characteristic such as anti-extrusion, but when some relatively large machinery component are installed, be flexible coupling because the connection between component belongs to, thus require that seal ring not only has the basic roles such as sealing, but also good cushioning effect will be had, therefore be necessary to propose to improve.
Model utility content
The technical problem that the utility model solves: a kind of hermetically sealed seal ring is provided, by adopting square structure and special-shaped cross section, and seal a certain amount of gas up for safekeeping at the hermetically sealed inner chamber of ellipse, constitute one and be applicable to relatively large equipment component and install and there is good sealing effect, good, the easy location and installation of damping property, the seal ring that not yielding, long service life, structure are simple, easy to use.
The technical solution adopted in the utility model: hermetically sealed seal ring, there is seal ring main body, described seal ring main body is square structure, described seal ring body interior is provided with oval hermetically sealed inner chamber, sealed gas up for safekeeping in described hermetically sealed inner chamber, the cross section of described seal ring main body is made up of oval ring, back taper lip and triangle.
Wherein, the lower end of the oval ring in described cross section is connected as one by joint and back taper lip, connection transition position between described oval ring and back taper lip is arc transition, and the both sides, upper end of described oval ring are provided with and connect as one triangle with it.
Further, the material of described seal ring main body is high-low temperature resistant rubber.
Described gas is the air pressure range 0.1-0.3Mpa of air, described gas.
The utility model advantage compared with prior art:
1, the utility model adopts and seals a certain amount of gas up for safekeeping at the hermetically sealed inner chamber of ellipse, and flexible seal ring main body is combined with flexible gas and makes seal ring have good cushioning effect;
2, the material of seal ring main body adopts rubber to make, and has good recoverability, makes seal ring not yielding and returns to prototype at once after distortion;
3, the gas in seal ring inner chamber adopts nitrogen, and due to nitrogen chemical property pole torpescence, not easily expand with heat and contract with cold, amplitude of deformation is little, has stable air pressure, so seal ring good stability, long service life;
4, this seal ring adopts square structure, and the installation between the component being specially adapted to relatively large equipment, can realize the sealing to liquids and gases effective and safe;
5, cross section adopts the profiled-cross-section that oval ring, back taper lip and triangle are formed, and easily installs, easily locates during use;
6, due to the form structure that the utility model is special, component position of installing corresponding to it does not need fine finishing;
The performance such as 7, there is good sealing effect, good, the easy location and installation of damping property, not yielding, long service life, structure are simple, 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.
Hermetically sealed seal ring, has seal ring main body 1, and described seal ring main body 1 is square structure, and employing square structure is specially adapted to the installation between the component of relatively large equipment, can realize the sealing to liquids and gases effective and safe; Described seal ring main body 1 inside is provided with oval hermetically sealed inner chamber 2, gas 3 has been sealed up for safekeeping in described hermetically sealed inner chamber 2, adopt and seal a certain amount of gas 3 up for safekeeping at the hermetically sealed inner chamber 2 of ellipse, flexible seal ring main body 1 is combined with flexible gas 3 and makes seal ring have good cushioning effect; The cross section of described seal ring main body 1 is mainly made up of oval ring 11, back taper lip 12 and triangle 13, the lower end of described oval ring 11 is connected as one by joint 14 and back taper lip 12, connection transition position 15 between described oval ring 11 and back taper lip 12 is arc transition, the both sides, upper end of described oval ring 11 are provided with and connect as one triangle 13 with it, adopt oval ring, back taper lip and triangle to form special-shaped cross section, easily install during use, easily locate; The material of described seal ring main body 1 is high-low temperature resistant rubber, and rubber has good recoverability, makes seal ring not yielding and returns to prototype at once after distortion; Described gas 3 is the air pressure range 0.1-0.3Mpa of air, described gas, and due to nitrogen chemical property pole torpescence, not easily expand with heat and contract with cold, amplitude of deformation is little, has stable air pressure, so seal ring good stability, long service life; In addition, due to the form structure that the utility model is special, component position of installing corresponding to it does not need fine finishing, and there is good sealing effect, good, the easy location and installation of damping property, the performance such as not yielding, long service life, structure are simple, 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.
