Description

Technical Field

[0002] C-type sealing rings are mainly used in special working conditions with high temperature, high pressure, high vacuum, ultra-low temperature, long life, extremely low leakage rate and large pressure and temperature cycle requirements, such as grooved flanges or flat flanges of pressure vessels, heat exchangers, gas turbines, ultra-high vacuum equipment, semiconductor equipment and special valves. In the high-temperature sealing of radiation furnace tube quenchers, C-type sealing rings can play an important role to ensure the normal operation and safety of the equipment; C-type sealing rings generally use high-performance materials such as nickel-based alloys as their structural skeleton. These materials have the characteristics of high temperature resistance, high pressure resistance, aging resistance, high strength, etc., and can meet the stringent requirements of high-temperature sealing of radiation furnace tube quenchers.

[0003] In the prior art, there is an ultra-high vacuum elastic energy storage metal sealing ring and its manufacturing method, such as the publication number CN116592141A, in which the sealing ring includes a sealing ring body, a sealing ring interlayer and a sealing ring outer layer arranged in sequence from the inside to the outside, the radial cross section of the sealing ring body is O-shaped, the radial cross sections of the sealing ring interlayer and the sealing ring outer layer are respectively C-shaped with a notch, and the upper and lower sides of the sealing ring outer layer are respectively horizontal planes with a sealing protrusion in the middle. The manufacturing method is to first use cold-drawn steel wire to make the sealing ring body to form an annular O-shaped spring; then, on the basis of the sealing ring body, use nickel alloy thin sheets to make the sealing ring interlayer; then, on the basis of the sealing ring interlayer, use pure aluminum ring belt or pure platinum ring belt to make the sealing ring outer layer, and cut and form the sealing protrusion on the sealing ring outer layer.

Figure 4 As shown, the upper matching panel 33 and the lower matching panel 43 are higher than the sealing outer ring 1 and the sealing inner ring 2, and at this time, the upper matching embedded top 32 and the lower matching embedded top 42 together with the upper ring cover plate 3 and the lower ring cover plate 4 are just snapped with them, and the upper snap ring plate 34 and the lower snap ring plate 44 are adapted to form a quick docking of the inner cavity of the upper matching panel 33 and the lower matching panel 43, and the spliced ​​upper snap ring plate 34 and the lower snap ring plate 44 can form a connecting piece and penetrate the inner wall of the upper matching panel 33 and the lower matching panel 43, thereby increasing the installation structure strength between the upper ring cover plate 3, the lower ring cover plate 4 and the sealing outer ring 1 and the sealing inner ring 2; and through the snap connection of the upper snap ring plate 34 and the lower snap ring plate 44, the supporting strength of the combined C-shaped ring can be improved to avoid stress deformation during the adaptation and extrusion of the radiation furnace tube quencher.

[0023] Embodiment 3, refer to the attached Figure 1-19 On the basis of the second embodiment, in order to ensure that the upper ring cover plate 3 and the lower ring cover plate 4 are squeezed from the outside and increase the self-tightening of the sealing surface and the C-ring: the elastic extrusion component includes a support sleeve 321, the support sleeve 321 is a hollow columnar structure, the lower end of the support sleeve 321 is movably abutted against the inner surface of the upper matching panel 33, the upper end of the support sleeve 321 is fixedly connected to the inner wall of the upper matching embedded top 32, and a sliding block 322 is slidably connected to the inner wall of the support sleeve 321, and the cross-section of the sliding block 322 is a "T"-shaped structure; the lower end of the sliding block 322 is fixedly connected to the abutment The contact rod 323 and the sleeve spring 324, the sleeve spring 324 is movably sleeved on the outside of the contact rod 323, the lower end of the contact rod 323 is fixedly provided with a conical angle 3231, the lower outer surface of the contact rod 323 passes through the bottom of the support sleeve 321 and is slidably connected to the inner wall of the reserved groove, and the lower end of the sleeve spring 324 is fixedly connected to the bottom surface of the inner cavity of the support sleeve 321; a horizontal groove 20 is opened on the central inner wall of the sealing inner ring 2, and a push rod 325 is movably connected to the inner surface of the horizontal groove 20, and one end of the push rod 325 is movably abutted against the outer surface of the conical angle 3231; In this embodiment, when the upper ring cover plate 3 and the lower ring cover plate 4 are squeezed from both sides, the upper protruding ring 31 and the lower protruding ring 41 cooperate with the elastic squeezing components on the inner sides of the upper matching embedded top 32 and the lower matching embedded top 42 respectively. Since the elastic squeezing components on the inner sides of the upper matching embedded top 32 and the lower matching embedded top 42 have the same structure, the structure on the inner side of the upper matching embedded top 32 is illustrated below by way of example: when the upper protruding ring 31 is continuously squeezed inward by the outer contact surface, the top of the sliding block 322 is squeezed. At this time, the sliding block 322 drives the resisting rod 323 to move inward, and the sleeve spring 324 is squeezed to produce compression deformation, such as Figure 4-Figure 5 As shown, the conical angle 3231 set at the end of the resistance rod 323 squeezes the push rod 325 on one side, and the push rod 325 moves horizontally, thereby driving the push rod 325 to push the inner elastic tight ring 23 to move outward, and the inner elastic tight ring 23 is deformed to fit the inner contact surface to be sealed, thereby reducing the contact gap. In this way, it is ensured that the C-ring can withstand the plastic deformation on both sides, and the gap compensation between the inner elastic tight ring 23 and the inner contact surface is simultaneously realized, thereby further improving the sealing effect of the C-ring.

[0024] Embodiment 4, refer to the attached Figure 1-19 On the basis of the third embodiment, in order to realize the elastic deformation of the fixed ring plate 22 and make up for the joint surface gap between the sealing inner ring 2 and the device to be sealed: the inner ring surface of the sealing outer ring 1 is fixedly provided with a protruding lining 12, the outer ring surface of the sealing inner ring 2 is fixedly provided with a protruding lining 201, and the inner ring surface of the sealing inner ring 2 is fixedly provided with a fixed ring plate 22. The fixed ring plate 22 is provided with six groups and arranged in a circular array about the central axis of the sealing inner ring 2. The inner wall of the fixed ring plate 22 is provided with a protruding groove 220, and the inner surface of the protruding groove 220 is matched with the outer surface of the fixed ring plate 22 one by one; the two sides of the inner elastic tight ring 23 are respectively fixedly connected with the inner surface of the fixed ring plate 22, the inner elastic tight ring 23 is movably installed on the inner side of the fixed ring plate 22, the inner wall of the inner elastic tight ring 23 is provided with a heat dissipation through hole 230, and one side surface of the inner elastic tight ring 23 is fixedly connected with one end of the push rod 325; In this embodiment, the boss 21 is integrally formed with the sealing inner ring 2, the protruding groove 220 provided on one side of the fixed ring plate 22 is adapted to the position of the boss 21, and the protruding lining 201 at this time serves as a movable channel for the push rod 325, and the deformation degree of the inner elastic tight ring 23 can be controlled according to the pushing distance of the push rod 325. It is worth noting that a heat dissipation through hole 230 is provided on the inner wall of the inner elastic tight ring 23, and the position of the heat dissipation through hole 230 is distributed at the horizontal position of the boss 21. When the inner elastic tight ring 2 When the inner elastic ring 23 is not pushed by the push rod 325 and is not deformed, the heat dissipation hole 230 is in contact with the boss 21, and the heat dissipation hole 230 is in a blocked state. When the inner elastic ring 23 is pushed by the push rod 325 and deformed, the middle of the inner elastic ring 23 is away from the boss 21, and the heat dissipation hole 230 is in an open state. This design can release the air pressure in the closed cavity formed by the inner elastic ring 23 and the fixed ring plate 22 to avoid damage and compression of various components.

[0025] The working principle and use process of the present invention are as follows: first, the C-shaped ring is set as a plurality of combined rings to form an assembly. When the C-shaped ring is assembled, the upper matching panel 33 and the lower matching panel 43 are relatively distributed to connect the sealing outer ring 1 and the sealing inner ring 2. This is used as the basis of the skeleton mechanism. The upper matching embedded top 32 and the lower matching embedded top 42 are respectively adapted and embedded with the upper matching panel 33 and the lower matching panel 43. The upper snap-fit ​​ring plate 34 and the lower snap-fit ​​ring plate 44 are adapted to form a quick docking of the inner cavity of the upper matching panel 33 and the lower matching panel 43. The spliced ​​upper snap-fit ​​ring plate 34 and the lower snap-fit ​​ring plate 44 can form a connecting piece and penetrate the inner wall of the upper matching panel 33 and the lower matching panel 43, thereby increasing the installation structure strength between the upper ring cover plate 3, the lower ring cover plate 4 and the sealing outer ring 1 and the sealing inner ring 2. Subsequently, when the upper ring cover plate 3 and the lower ring cover plate 4 are subjected to the pressure from both sides, the upper ring cover plate 3 and the lower ring cover plate 4 are fastened to the sealing outer ring 1 and the sealing inner ring 2. When the upper protruding ring 31 and the lower protruding ring 41 are squeezed, they cooperate with the elastic extrusion components on the inner sides of the upper matching embedded top 32 and the lower matching embedded top 42 respectively. When the upper protruding ring 31 is continuously squeezed inward by the outer contact surface, the top of the sliding block 322 is squeezed. At this time, the sliding block 322 drives the contact rod 323 to move inward, and the sleeve spring 324 is squeezed to produce compression deformation. The tapered angle 3231 set at the end position of the contact rod 323 squeezes the push rod 325 on one side, and the push rod 325 moves horizontally, thereby driving the push rod 325 to push the inner elastic tight ring 23 to move outward. The inner elastic tight ring 23 is deformed and fits with the inner contact surface to be sealed to reduce the contact gap. In this way, it ensures that the C-shaped ring can withstand the plastic deformation on both sides, and simultaneously realizes the gap compensation between the inner elastic tight ring 23 and the inner contact surface.
