Abstract
The utility model discloses a sealing washer with interior location structure, including the sealing washer body, the inside hollow structure that is of sealing washer body, just an annular opening has been seted up to the inner wall, just annular opening with the sealing washer body is coaxial, the annular opening inside callipers is equipped with the spring buckle structure. The sealing ring of the utility model is a C-shaped sealing ring, a spring buckle structure is clamped at the inner opening, and the buckle conveniently clamps inner shafts or bolts and other installation workpieces, and is convenient to use during installation; meanwhile, two annular strips are arranged inside the sealing ring, an annular cavity is formed between the two annular strips and the sealing ring body, and inert gas is filled in the annular cavity, so that the rigidity of the whole sealing ring is improved, and the resistance to high-temperature loss and the like is improved.
Description
Technical Field
The utility model relates to a sealing washer technical field especially relates to a sealing washer with interior location structure.
Background
The sealing ring plays an important role in sealing the connection relationship of the two parts, so that the gap between the two parts is reduced, and the structure and the material selection of the sealing ring have important significance on the sealing performance and the service life of the sealing ring; the sealing position of the pipeline joint is generally realized by a metal sealing ring, the joint of the existing pipeline is generally realized by structures such as flanges, but the existing sealing ring structure adopts an annular sheet or is additionally provided with a plurality of annular grooves, so that the sealing property and the applicability are poor; aiming at the problem, a C-shaped sealing ring is provided at present, and the sealing ring forms a contact pressure between a reinforced sealing ring and a rigid body under the action of medium internal pressure, so that the sealing ring can be suitable for the sealing problems of high temperature resistance, high pressure resistance, corrosion resistance and the like in a fluid sealing system; however, the existing C-shaped sealing ring has the problems that the installation workpiece is not convenient to clamp when the C-shaped sealing ring is installed and fixed, and the installation action is inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a sealing ring with an internal positioning structure.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a sealing washer with interior location structure, includes the sealing washer body, the inside hollow structure that is of sealing washer body, and its inner wall has seted up an annular opening, just annular opening with the sealing washer body is coaxial, the inside card of annular opening is equipped with spring buckle structure.
Preferably, the spring snap structure extends out of the annular opening.
Preferably, the sealing ring body is internally and symmetrically provided with two annular strips, the two annular strips are fixedly connected with the sealing ring body, and two annular cavities are formed between the annular strips and the sealing ring body.
Preferably, both said annular chambers are filled with an inert gas.
Preferably, both of said annular strips are arcuate in cross-section.
Compared with the prior art, the beneficial effects of the utility model are that: the sealing ring can be flexibly used for a non-planar flange, has the characteristics of high-temperature strength, good resilience, corrosion resistance, fatigue resistance and the like, is particularly suitable for sealing high-temperature high-pressure high-vacuum media, and adopts the addition of the strength of a jacket and hydrostatic pressure to increase the sealing force at higher pressure; meanwhile, compared with the common C-shaped sealing ring, the sealing ring is provided with a spring buckle structure at the position of the inner opening, and the spring buckle structure is convenient for clamping inner shafts or bolts and other installation workpieces and can be used conveniently during installation; further, this sealing washer has still set up two annular strips inside, all forms annular cavity and fills inert gas between two annular strips and the sealing washer body, has at first increased the rigidity of sealing washer, can utilize inert gas's high temperature expansion characteristic to resist the intensity loss under the high temperature simultaneously when actually carrying out the use, and the curved setting of annular strip can let the better effort of inside medium provide stress at two annular strips moreover.
Drawings
Fig. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic view of the vertical cross-sectional structure of the present invention;
fig. 3 is a schematic view of the horizontal cross-sectional structure of the present invention.
In the figure:
1 sealing washer body, 2 spring buckle structures, 3 annular strips.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a seal ring with an inner positioning structure includes:
the sealing ring comprises a sealing ring body 1, wherein the interior of the sealing ring body 1 is of a hollow structure, an annular opening is formed in the inner wall of the sealing ring body 1, and the annular opening is coaxial with the sealing ring body 1, so that the sealing ring body 1 forms a C-shaped sealing ring structure, the using effect of the whole sealing ring is improved, a spring buckle structure 2 is clamped in the annular opening, the spring buckle structure 2 extends out of the annular opening, and the spring buckle is convenient for clamping mounting workpieces such as an inner shaft or a bolt and the like and is used in the aspect of mounting;
two annular strips 3 are symmetrically arranged in the sealing ring body 1, the two annular strips 3 are both fixedly connected with the sealing ring body 1, annular chambers are formed between the two annular strips 3 and the sealing ring body 1, the design of the two annular strips 3 does not influence the arrangement of the spring buckle structure 2 at first, and the two annular strips 3 can increase the rigidity of the whole sealing ring, meanwhile, because the metal material is lost in a high-temperature state, the compensation effect can be achieved through the thermal expansion effect of the inert gas, but the inert gas is not convenient to be directly filled in the sealing ring, and the arrangement of the structure is influenced by the existence of the spring buckle structure 2, therefore, the two annular chambers are filled with the inert gas, the high-temperature metal loss is compensated through the high-temperature expansion property of the inert gas, the sections of the two annular strips 3 are arc-shaped, when the medium enters the sealing ring, the contact surface is the arc, can let internal pressure better act on the sealing washer, increases the sealing washer leakproofness.
The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
