SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing an inflatable sealing ring.
In order to realize the purpose, the utility model adopts the following technical scheme:
an inflatable gasket comprising:
the sealing ring comprises a sealing ring body, a sealing ring body and a sealing ring body, wherein the sealing ring body is internally provided with a hollow structure, and a certain amount of gas is filled in the sealing ring body;
the sealing ring is characterized in that a through hole communicated with the inside is formed in one side of the sealing ring body, a valve core is arranged in the through hole in a sealing mode, a reinforcing block is fixedly arranged on the sealing ring body corresponding to the valve core, and cylindrical protrusions matched with the valve core are arranged on the reinforcing block.
Preferably, the cross section of the sealing ring body is O-shaped.
Preferably, the gas filled in the sealing ring body is inert gas.
Preferably, the upper side and the lower side of the sealing ring body are respectively and fixedly provided with an annular contact bulge correspondingly.
Preferably, sealing washer body one side is provided with the metal enclosed piece, the metal enclosed piece corresponds with the protruding position of cylinder type, the metal enclosed piece is surrounded around being provided with a plurality of triangle legs, be provided with a plurality of spacing recesses that match with the triangle leg on the protruding lateral wall of cylinder type on the reinforcing block.
Compared with the prior art, the beneficial effects of the utility model are that: the sealing ring is designed into a hollow sealing ring structure, the cross section of the sealing ring is arranged into an O shape, the sealing ring has a small contact area when in sealing, the sealing stress is increased, and meanwhile, the O shape has a high bearing force effect, so that the using effect of the whole sealing ring is high; the sealing ring is filled with inert gas in the inner hollow part, and the strength loss of the metal sealing ring at high temperature is compensated by utilizing the characteristic that the gas expands at high temperature, so that the sealing ring is particularly suitable for an ultrahigh-temperature flange structure; in this sealing washer structure, in order to make things convenient for fill inert gas into inside the sealing washer, run through fixed valve inside on the sealing washer to set up reinforcing block and increased the connection steadiness and the leakproofness between valve inside and the sealing washer, still equipped with extra metal enclosed piece and be used for inlaying on the valve inside, simple structure just can guarantee the guard action.
