Abstract
The present invention relates to a T-shaped pressure container sealing ring which is used for sealing general pressure containers and daily pressure cookers and is composed of a ring body and a ring edge perpendicular to the ring body, wherein a plane surface perpendicular to the ring body is arranged on the inner side of the ring edge, and one or more one sealing rib is arranged on the outer side of the ring edge. The sealing performance is enhanced greatly, and the service life is extended in multiples. The T-shaped pressure container sealing ring also has the advantages of simple structure and convenient use and is a product capable of replacing a sealing ring for general pressure containers and daily pressure cookers.
Description
Technical field
The present invention relates to the sealing of general pressurized container, the sealing of daily pressure cooker.
Background technique
Y shape rubber seal is all adopted in the sealing of existing general pressurized container, daily pressure cooker.This seal ring has had NBS: GB4864-84 " rubber sealing ring for pressure cooker ", as shown in Figure 2.Two sealing strips of this seal ring are close to the circular arc portion of pressurized container and realize sealing under the effect of pressurized gas, i.e. cambered surface sealing.The Chinese patent about seal ring of Gong Buing is all thought hard on two sealing strips of y-shaped ring in recent years, increases the addition such as " muscle ", to strengthen sealability, increases the service life.For example CN91106681.0 " gas-filled type rubber seal and sealing configuration thereof " increases " muscle " on sealing strip, forms the hollow ring of sealing.In actual use, no matter increase how many annexes on two sealing strips of y-shaped ring, effect is not ideal.
Summary of the invention
The present invention's purpose is to disclose a kind of sealability breakthrough raising, and be doubled and redoubled working life, T shape pressure container sealing ring simple in structure, easy to use.
The present invention adopts the seal ring of T shape structure, changes the scheme that cambered surface is sealed into plane sealing and realizes above-mentioned purpose.
T shape pressure container sealing ring is made up of circle body and the circle limit vertical with circle body, and the inboard on circle limit is the plane vertical with circle body.There are one or more sealed muscles in the outside on circle limit, and one or two positioning bars are arranged on the circle body.The sectional shape semicircular in shape of sealed muscle or oval or triangle or trapezoidal.
Description of drawings
Accompanying drawing 1,3-9 are embodiment one to eight sectional drawings, and accompanying drawing 2 is NBS y-shaped ring sectional drawings.Wherein the embodiment shown in the accompanying drawing 1 one is the sectional drawing that is contained in the pressurized container.
Embodiment
Shown in accompanying drawing 1,3-9, T shape pressure container sealing ring is made up of circle body 3 and the circle limit 1 vertical with circle body 3.The inboard on circle limit 1 is the plane vertical with circle body 3.There are one or more sealed muscles 2 in the outside on circle limit 1.Circle body 3 can be an arc with the connecting part on circle limit 1, shown in accompanying drawing 1,3,5-9, also can be linear, as shown in Figure 4.The end of circle body 3 can be a cylindricality, also can be spherical.Sealed muscle 2 have only one shown in accompanying drawing 1,3-5 and 9, have two shown in accompanying drawing 6-8.
Shown in accompanying drawing 1,3-9, the sectional shape semicircular in shape of sealed muscle 2 or oval or triangle or trapezoidal or other geometrical shapies.Accompanying drawing 1 and 6 sealed muscle 2 semicirculars in shape, accompanying drawing 5 ovalizes, accompanying drawing 4 is triangular in shape, accompanying drawing 3 is trapezoidal, accompanying drawing 9 is other geometrical shapies, and 2 one semicirculars in shape of the sealed muscle of accompanying drawing 7, another is triangular in shape, and 8 one semicirculars in shape of accompanying drawing, another is trapezoidal.Certainly, sealed muscle 2 can also have 3,4 or the like.The seal ring of a plurality of sealed muscles 2, the sectional shape of its sealed muscle 2 can independent assortment.
Shown in accompanying drawing 5 and 7, also have one or two positioning bars 4 on the circle body 3.Certainly, there is not positioning bar 4 in other accompanying drawings.The effect of positioning bar 4 is to guarantee that seal ring is in moderate position between container body and container cover, to guarantee that sealed muscle 2 is on the vertical surface of container body and container cover.
Obviously, the T shape seal ring of the plane sealing pressure surface of being bullied is long-pending big, not yielding, even used for a long time, sealed muscle 2 does not play plane sealing, the effect that circle limit 1 also has cambered surface to seal.Therefore this seal ring has sealability advantage such as are doubled and redoubled in breakthrough raising, working life, simple in structure, easy to use is arranged, and is the update product of general pressurized container, daily pressure cooker seal ring.
In the embodiment shown in the figures, accompanying drawing 1,3-5 are that specification is the daily pressure cooker seal ring of 20cm, 22cm, and accompanying drawing 6 and 7 is general pressure container sealing rings, and accompanying drawing 8 and 9 is that specification is the daily pressure cooker seal ring of 24cm, 26cm.
Claims (1)
1, a kind of T type pressure container sealing ring, form by circle body (3) and the circle limit (1) vertical with circle body (3), the inboard on circle limit (1) is and the vertical plane of circle body (3), it is characterized in that there are one or more sealed muscles (2) in the outside of enclosing limit (1), one or two positioning bars (4) are arranged, the sectional shape semicircular in shape of sealed muscle (2) or oval or triangle or trapezoidal on the circle body (3).
