Abstract
The invention provides a sealing device applicable to a high-temperature and high-pressure environment and relates to a sealing device. The inner side surface of a reinforced ring plate (3) is provided with an inner bulge strip (1); the outer surface of a rubber strip (5) is provided with a narrow slot (11) which corresponds to the inner bulge strip (1); the inner bulge strip (1) of the reinforced ring plate (3) is inserted in the narrow slot (11) in the outer surface of the rubber strip (5). According to the sealing device applicable to the high-temperature and high-pressure environment, local loosening caused by outward displacement of the rubber strip is restricted by use of the reinforced ring plate and the inner bulge strip, stable seal of the rubber strip in the high-temperature and high-pressure environment is achieved, and the displacement problem brought by ageing of the rubber strip is effectively delayed.
Description
[technical field]
The present invention relates to a kind of seal arrangement, be specifically related to a kind of seal arrangement being applicable to high temperature, hyperbaric environment.
[background technique]
Known, seal ring is all almost O shape structure, and cross section is the rubber ring of rectangular or circle, and seal ring is most popular a kind of Sealing in hydraulic pressure, pneumatic system.Seal ring has good sealing, both can be used for static seal, also can be used in reciprocating movement sealing; Not only can be used alone, and be element in many sealer with assembled, the seal ring of rectangular cross-sectional is used in equipment pipe or adpting flange, sealing is obtained by extruding, the basic functional principle of extrusion pressing type sealing relies on Sealing generation resiliently deformable, and sealing contact surface causes contact, and contact is greater than the interior pressure of sealed medium, then do not leak, otherwise then leak; But during due to liquid medium sealing to pipeline, because the reasons such as time, high temperature or high pressure can make rubber ring aging, occur further leaking, to be under pressure and displacement is ineffective.
[summary of the invention]
In order to overcome deficiency of the prior art, the invention discloses a kind of seal arrangement being applicable to high temperature, hyperbaric environment, utilize the partial relaxation caused to outer displacement of enforced loop plane and internal projection bar restriction rubber strip, obtain the stabilized seal of rubber strip under high temperature, hyperbaric environment, effectively delay the aging displacement problem brought of rubber strip.
In order to realize described goal of the invention, the present invention adopts following technology:
A kind of seal arrangement being applicable to high temperature, hyperbaric environment, comprise enforced loop plane and rubber strip, the inner side surface of enforced loop plane is provided with internal projection bar, and the exterior face of rubber strip is provided with the narrow groove of corresponding internal projection bar, the internal projection bar of enforced loop plane be inserted in rubber strip exterior face narrow groove in.
The described seal arrangement being applicable to high temperature, hyperbaric environment, be provided with spheric end in internal projection bar the inner of enforced loop plane, the groove bottom of the narrow groove of described rubber strip is provided with spherical groove, and the spheric end of internal projection bar is stuck in the spherical groove of described narrow groove.
The described seal arrangement being applicable to high temperature, hyperbaric environment, the outer edge surface of described rubber strip is provided with sipes, and enforced loop plane is stuck in described sipes.
The described seal arrangement being applicable to high temperature, hyperbaric environment, the upper side and bottom surfaces of rubber strip are respectively equipped with at least one " V " shape raised item.
The described seal arrangement being applicable to high temperature, hyperbaric environment, passes through chamfered transition between the inner face of described rubber strip and upper side, bottom surfaces.
Owing to have employed technique scheme, the present invention has following beneficial effect:
The seal arrangement being applicable to high temperature, hyperbaric environment of the present invention, limits the partial relaxation caused to outer displacement of rubber strip by enforced loop plane, by internal projection bar make the form of rubber strip high temperature, hyperbaric environment stable; The present invention can limit that the transition of rubber strip under long-term high pressure, hot environment is lax, displacement and deterioration phenomenon, obtains the guarantee of rubber ring elasticity and airtight quality; Structure of the present invention is simple, and user cost is lower
