Abstract
The utility model relates to a self-tight seal ring; the interior of an annular elastic member is provided with a hollow cavity; thermal expansion medium with heat expansion and cold contraction effect is filled with the hollow cavity. The utility model can realize self-tight seal depending on the thermal expansion feature of the medium, and has the advantages of sealing effect and long service life, being used for cooker, machine, chemical equipment, various conveyance fluid, and gas pipeline sealing.
Description
The utility model relates to a kind of seal element, relates in particular to a kind of seal ring of pressurization cooking-vessel for kitchen use.
Existing seal element mostly is solid, it seals the pressuring action of the plasticity, elasticity and the external force that mainly rely on sealing material or claims externally screwed effect, in case the elasticity of seal element, plasticity and external force lose wherein any one, its sealing effect just reduces greatly.For moving sealing element, because of constantly wearing and tearing, sealing effect is used poorer and poorer in the course of the work for it.Existing seal element mostly is rubber material, and rubber at high temperature easily wears out and follows the string, and shortened working life, and existing seal element needs the external force effect, and materials consumption is more, and sealing effect is relatively poor.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and a kind of seal ring of realizing self-energized seal, good sealing effect, long service life, saving material is provided.
The purpose of this utility model can reach by following measure:
A kind of self-fastening ring comprises a ring elastic parts, and its special way is: be provided with cavity in the described elastic component, the thermal expansion medium is housed in the cavity.
Cavity of the present utility model can be single hole cavity or cellular porous cavity.
Thermal expansion medium of the present utility model can be gas, liquid or gas-liquid mixture.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is the utility model embodiment 1 a outline drawing;
Fig. 2 is the utility model embodiment 1 a structural representation;
Fig. 3～6 are respectively the utility model embodiment 2～5 structural representation.
Below in conjunction with accompanying drawing the utility model is elaborated:
Referring to Fig. 1～2, seal ring is made of ring elastic parts 1, and its profile can be designed to circular seal ring.Elastic component 1 is a hollow object, promptly has a cavity 2 in the elastic component 1, and cavity 2 can be the single hole cavity, also can be cellular porous cavity, can charge into inflating medium in the cavity 2, inflating medium can be a gas, also can be the volatile liquid of low boiling, can also be gas, liquid mixture.Elastic component 1 of the present utility model can adopt materials such as rubber, plastics, plastic cement, if inflating medium gas then can adopt CO
2, N
2Deng; If inflating medium liquid then can adopt low boiling volatile liquids such as water, alcohol; Cavity 2 is if adopt the single hole cavity, and then its shape of cross section can be trapezoidal, circular, oval a, triangle etc.The shape of seeing Fig. 3～6 elastic components 1 also can be designed to it cross section as required and be shapes such as circle, ellipse, triangle, trapezoidal, polygonal.During use, seal ring is positioned over sealing part, needn't exerts pressure, with flat getting final product on the link elastic component 1.Because sealed material operating temperature and pressure all are higher than ambient temperature and pressure, the gas in the seal ring elastic component 1 is expanded for this temperature difference and pressure difference or liquid evaporation expands, pressure in the cavity 2 rises, and elastic component 1 is expanded, and sealing part is by tight seal.When cutting off sealed material or reducing its operating temperature or pressure, temperature, pressure decreases in the elastic component 1, and seal ring restores to the original state gradually.Impacting force sheds voluntarily.
The utility model compared with prior art has following advantage:
1, adopt self-energized seal, sealing effectiveness is good.
2, sealing ring resilient makes big leap ahead in service life.
3, can save manpower, during especially for engineering field.
4, adopt hollow-core construction, save raw material.
5, can be widely used in the sealing of cooker, machinery, chemical industry equipment and various conveyance fluid, gas piping.
Claims (3)
1, a kind of self-fastening ring comprises a ring elastic parts, it is characterized in that: be provided with cavity in the described elastic component, the thermal expansion medium is housed in the cavity.
2, as claim 1 or described self-fastening ring, it is characterized in that: described cavity is single hole cavity or cellular porous cavity.
3, self-fastening ring as claimed in claim 2 is characterized in that: described thermal expansion medium is gas, liquid or gas-liquid mixture.
