Description

Technical Field

[0001] This utility model relates to the field of electrolytic cells for hydrogen production by water electrolysis, and in particular to a sealing gasket support clamp for an electrolytic cell. Background Technology

[0002] The sealing gaskets of large-scale water electrolysis hydrogen production electrolyzers are mainly composed of polymer materials such as rubber and PTFE. These materials have low rigidity and are prone to creep, relaxation, and cold flow, which can cause permanent deformation of the gaskets. They are also highly sensitive to temperature, with a large coefficient of linear expansion, resulting in poor dimensional stability under temperature changes. Long-term storage and transportation can cause dimensional changes, rendering the gaskets unusable. Currently, many large-scale water electrolysis hydrogen production electrolyzers are used in cold regions, and the gaskets stored there experience significant dimensional shrinkage, making them unsuitable for long-term storage as spare parts. Utility Model Content

[0003] The purpose of this utility model is to provide a gasket support fixture for electrolytic cells, which prevents the gaskets used in electrolytic cells from easily deforming during storage or transportation, and keeps the dimensions of the gaskets stable.

[0004] This utility model provides a sealing gasket support clamp for an electrolytic cell, comprising: Base; Support column, the support column is fixedly installed on the base, and the support column is used to fit the sealing gasket; A clamping ring is movably fitted around the outer periphery of the support column along the axial direction of the support column. The clamping ring is used to apply a clamping force toward the base to the sealing gasket between the clamping ring and the base.

[0005] In the above technical solution, the base serves as a support platform, with the support column fixedly mounted on it for positioning and mounting the sealing gaskets. A clamping ring is coaxially fitted around the support column and can move axially along the support column, covering and pressing the upper surface of the sealing gaskets. During operation: multiple sealing gaskets are fitted onto the support column. Then, pressure is applied to the clamping ring towards the sealing gaskets via an external drive device or manually, driving the clamping ring to move along the support column towards the base, applying a clamping force to the sealing gaskets fitted onto the support column, thus constraining the sealing gaskets axially. Simultaneously, because the sealing gaskets are fitted onto the support column, the support column also radially restricts the deformation of the sealing gaskets. Through the synergistic effect of the radial deformation restriction of the support column and the axial deformation restriction of the clamping ring, the axial clamping force inhibits creep relaxation of the sealing gasket material, and the radial support of the support column inhibits radial deformation of the sealing gaskets, ensuring that the sealing gaskets maintain their initial shape and dimensions throughout storage or transportation.

[0006] In some possible implementations, the clamping ring has at least one positioning hole corresponding to the flow channel hole on the sealing gasket, and the base has at least one support rod, with the clamping ring movably fitted onto the support rod through the positioning hole.

[0007] In some possible implementations, the number of positioning holes and support rods are the same as the number of flow channel holes on the sealing gasket and correspond one-to-one.

[0008] In some possible implementations, the cross-sectional area of ​​the support rod is 10 mm². 2 ~500mm 2 And / or, the cross-sectional shape of the support rod includes at least one of waist-shaped, circular, or rectangular.

[0009] In some possible implementations, the electrolytic cell gasket support fixture also includes a clamping assembly, which includes a drive component and a frame. The drive component is disposed between the frame and the clamping ring and is used to drive the clamping ring to move axially along the support column.

[0010] In some possible implementations, the frame includes a first vertical bar, a horizontal bar, and a second vertical bar connected in sequence, with the horizontal bar located on the side of the support column away from the base. Both the first and second vertical bars are detachably connected to the base, and the drive component is located between the clamping ring and the horizontal bar.

[0011] In some possible implementations, the driving component includes a hydraulic cylinder, with the fixed end of the hydraulic cylinder disposed on the clamping ring and the driving end of the hydraulic cylinder abutting against the crossbar; And / or, the drive component includes a cylinder or a linear motor, the fixed end of which is detachably mounted on the crossbar, and the drive end of which is abutted against the clamping ring.

[0012] In some possible implementations, the outer diameter of the base and / or the clamping ring is 100mm to 3000mm; and / or, the thickness of the base and / or the clamping ring is 3mm to 100mm.

[0013] In some possible implementations, the support column is a hollow support column.

[0014] In some possible implementations, the outer diameter of the support column is 100mm to 3000mm; and / or, the wall thickness of the hollow support column is 3mm to 100mm. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figure 1 As shown, this utility model embodiment provides a gasket support fixture for an electrolytic cell. The gasket support fixture for an electrolytic cell includes a base 100, a support column 200, and a clamping ring 300. The support column 200 is fixedly disposed on the base 100 and is used to fit the gasket. The clamping ring 300 is movably fitted around the outer periphery of the support column 200 along the axial direction of the support column 200 and is used to apply a clamping force toward the base 100 to the gasket between the clamping ring 300 and the base 100.

[0023] In specific implementation, such as Figure 3 As shown, multiple sealing gaskets 600 are fitted onto the support column 200. Then, pressure is applied to the clamping ring 300 towards the sealing gaskets via an external drive device or manually, driving the clamping ring 300 to move along the support column 200 towards the base 100. This applies a clamping force to the sealing gaskets 600 fitted onto the support column 200, thus constraining the sealing gaskets 600 axially. Simultaneously, because the sealing gaskets 600 are fitted onto the support column 200, the support column 200 also radially restricts the deformation of the sealing gaskets 600. Through the synergistic effect of the radially constrained deformation of the support column 200 and the axially constrained deformation of the clamping ring 300, the axial clamping force inhibits creep relaxation of the sealing gasket material 600, and the radial support of the support column 200 inhibits radial deformation of the sealing gaskets 600, ensuring that the sealing gaskets 600 maintain their initial shape and dimensions throughout storage or transportation.

[0024] Understandably, when pressure is applied to the clamping ring 300 toward the base 100, the clamping ring 300 contacts and presses against the upper surface of the sealing gasket 600. At this time, the clamping ring 300 can maintain its axial position by relying on the contact friction between its inner ring surface and the support column 200, thereby maintaining the clamping force on the sealing gasket 600 and constraining the axial deformation of the sealing gasket 600; or, the clamping ring 300 itself has a certain weight, and when the clamping ring 300 is pressed against the upper surface of the sealing gasket 600, it constrains the axial deformation of the sealing gasket 600 by its own weight.

[0025] In some embodiments, such as Figure 1As shown, the clamping ring 300 has at least one positioning hole that corresponds to the flow channel hole on the sealing gasket 600, and the base 100 is provided with at least one support rod 500. The clamping ring 300 is movably sleeved on the support rod 500 through the positioning hole.

[0026] Specifically, such as Figure 1 As shown, the clamping ring 300 has multiple positioning holes, the number of which can be one, two, three, six, ten, fifteen, or more. The positions of the positioning holes correspond to the positions of the flow channel holes on the sealing gasket 600. That is, when the clamping ring 300 is pressed against the upper surface of the sealing gasket 600, the positions of the positioning holes correspond to the positions of the flow channel holes. At least one support rod 500 is provided on the base 100, the number of support rods 500 corresponding to the number of positioning holes. The clamping ring 300 is movably fitted onto the support rod 500 through the cooperation of the positioning holes and the support rod 500. Specifically, the sealing gasket 600 has a first through hole at its axial center for the support column 200 to pass through, and multiple flow channel holes are formed around its axial periphery for the support rod 500 to pass through. During operation: When the sealing gasket 600 is fitted onto the support column 200 through its first through hole on its axis, the multiple flow channel holes distributed around the axis naturally pass through the multiple support rods 500. The positioning hole of the clamping ring 300 passes through the support rod 500, and the clamping ring 300 moves downward along the axial direction of the support rod 500 to clamp the sealing gasket 600. At this time, the support rod 500 and the support column 200 together form a radial constraint, which provides radial limiting effect on the outer edge area of ​​the gasket, preventing the sealing gasket 600 from radially expanding or twisting during clamping or storage and transportation. In this way, through the synergistic radial limiting formed by the support rod 500 and the support column 200, the constraint ability on the radial deformation of the sealing gasket 600 is enhanced while providing axial clamping force.

[0027] Furthermore, the number of positioning holes and support rods 500 are the same as the number of flow channel holes on the sealing gasket 600 and correspond one-to-one. That is, the number and arrangement of the positioning holes on the clamping ring 300 and the support rods 500 on the base 100 completely correspond to the flow channel holes on the sealing gasket 600, and each flow channel hole on the sealing gasket 600 has an independent positioning hole and support rod 500 to cooperate with it. During operation: When the sealing gasket 600 is installed, each of its flow channel holes can be fitted onto the corresponding support rod 500. Then, the clamping ring 300 moves axially along the support rod 500 through its positioning hole and presses against the upper surface of the uppermost sealing gasket 600. The positioning hole on the clamping ring 300 always maintains its correspondence with the flow channel hole of the sealing gasket 600 during the clamping process. Through this one-to-one corresponding positioning method, each flow channel hole on the sealing gasket 600 can obtain a uniform radial support force, effectively preventing deformation of the flow channel hole of the sealing gasket 600 due to uneven force during clamping and storage. This configuration ensures that the multiple flow holes on the sealing gasket 600 are radially supported by matching the flow holes, positioning holes, and support rods 500 one by one, thus reducing the possibility of deformation. It also reduces the assembly difficulty, as it only requires aligning the flow holes on the sealing gasket 600 with the support rods 500 and aligning the positioning holes on the clamping ring 300 with the support rods 500, thereby improving assembly efficiency.

[0028] In some embodiments, the cross-sectional area of ​​the support rod 500 is 10 mm². 2 ~500mm 2 And / or, the cross-sectional shape of the support rod 500 includes at least one of the following: oblong, circular, or rectangular. Specifically, the cross-sectional area of ​​the support rod 500 may be 10 mm². 2 100mm 2 200mm 2 300mm 2 400mm 2 Or 500mm 2 And any area within the interval. With this configuration, the cross-sectional area of ​​the support rod 500 is optimized to provide sufficient support strength while maintaining structural compactness. Through the precisely designed cross-sectional dimensions of the support rod 500, it can provide sufficient radial constraint strength without affecting the installation and positioning of the sealing gasket 600 due to an excessively large cross-section. This ensures that the sealing gasket 600 maintains its shape and precise hole alignment during compression operations and long-term storage and transportation, guaranteeing radial constraint.

[0029] In some embodiments, such as Figure 2As shown, the cross-sectional shape of the support rod 500 includes at least one of the following: waist-shaped, circular, or rectangular. One end of the support rod 500 is fixedly mounted on the base 100, and the other end extends upward and passes through the corresponding through holes on the clamping ring 300 and the sealing gasket 600. The cross-sectional shape of the support rod 500 can adopt various geometric shapes such as waist-shaped, circular, or rectangular to adapt to the shape of the through holes on the sealing gasket 600 and the clamping ring 300. With this configuration, when the sealing gasket 600 is fitted onto the support rod 500 through its circumferential through hole, the support rods 500 with different cross-sectional shapes can provide radial constraints with different forces on the outer edge area of ​​the gasket. The circular cross-section provides a uniform circumferential constraint force, while the rectangular or waist-shaped cross-section provides a larger contact area to enhance the deformation resistance of the sealing gasket 600. These support rods 500 with different shapes effectively prevent the gasket from deforming or displacing in various radial directions, maintaining stable geometric constraints on the sealing gasket 600.

[0030] In some embodiments, the electrolytic cell sealing gasket support fixture further includes a clamping assembly 400, which includes a driving component 410 and a frame 420. The driving component 410 is disposed between the frame 420 and the clamping ring 300 and is used to drive the clamping ring 300 to move axially along the support column 200.

[0031] Specifically, the frame 420 can be connected to the base 100 to form a support frame, or the frame 420 can be connected to an external structure to form a support frame, providing a connection position for the drive component 410. The drive component 410 is disposed between the frame 420 and the clamping ring 300, and can drive the clamping ring 300 to move axially along the support column 200 toward the base 100, thereby applying a clamping force to the sealing gasket 600. Through the continuous action of the drive component 410, the clamping ring 300 can maintain a constant clamping state on the sealing gasket 600, which can overcome the relaxation characteristics of the sealing gasket 600 material. With this configuration, the controllable drive mechanism provided by the clamping component 400 achieves precise pressure control of the sealing gasket 600, ensuring that the sealing gasket 600 is always in the optimal clamping state during transportation or storage.

[0032] Understandably, the drive component 410 can drive the clamping ring 300 to move toward the base 100 or away from the base 100. This configuration ensures that a precise and controllable axial clamping force can be applied to the sealing gasket 600. By controlling the drive component 410 to drive the clamping ring 300 away from or toward the base 100, the drive stroke and the pressure applied to the sealing gasket 600 can be controlled. This ensures that the sealing gasket 600 is adequately constrained and also avoids damage to the sealing gasket 600 material due to excessive pressure, increasing the flexibility of pressure adjustment on the sealing gasket 600.

[0033] In some embodiments, the frame 420 may include multiple longitudinal platforms disposed on the base 100 and extending parallel to the axial direction of the support column 200. A lead screw and slider mechanism and a drive motor are provided on the longitudinal platforms. The length direction of the lead screw of the lead screw and slider mechanism, i.e., the direction of movement of the slider, is parallel to the axial direction of the support column 200. The drive component 410 may include a rigid body structure detachably connected to the slider, one end of which may overlap the clamping ring 300. With the above technical solution, the connection between the rigid body structure and the slider is disconnected, allowing sufficient space for the multiple sealing gaskets 600 to be fitted onto the support column 200. Then, the clamping ring 300 is fitted onto the support column 200, with the clamping ring 300 positioned above the sealing gaskets 600. The rigid body structure is then connected to the slider, and the drive motor is started. This drives the slider, along with the rigid body structure, to press the clamping ring 300 downwards along the axial direction of the support column 200. The clamping ring 300 then compresses the sealing gaskets 600, completing the clamping operation.

[0034] It is understandable that the support column 200 is cylindrical. When the sealing gasket 600 is fitted onto the support column 200, the cylindrical support column 200 can apply uniform constraint to the radial direction of the sealing gasket 600, preventing deformation of the sealing gasket 600 caused by local stress concentration.

[0035] In some embodiments, such as Figure 1 As shown, the frame 420 includes a first vertical bar 421, a horizontal bar 422, and a second vertical bar 423 connected in sequence. The horizontal bar 422 is located on the side of the support column 200 away from the base 100. The first vertical bar 421 and the second vertical bar 423 are both detachably connected to the base 100. The drive component 410 is located between the clamping ring 300 and the horizontal bar 422.

[0036] The frame 420 is detachably connected to the base 100 via the first vertical rod 421 and the second vertical rod 423. The detachable connection includes the first vertical rod 421 and the second vertical rod 423 being bolted to the base 100. Specifically, the base 100 has threaded holes on its side, and the first vertical rod 421 and the second vertical rod 423 are threadedly connected to the side of the base 100 via bolts. When it is necessary to put the clamping ring 300 and the sealing gasket 600 onto the support column 200, the connection between the first vertical rod 421 and the second vertical rod 423 and the base 100 is disconnected, so that the crossbar 422 will not obstruct the movement path of the clamping ring 300 and the sealing gasket 600. After the clamping ring 300 and the sealing gasket 600 are installed, the first vertical rod 421 and the second vertical rod 423 are connected to the base 100 to complete the installation of the entire support fixture. A crossbar 422 connects to the top of the first vertical bar 421 and the second vertical bar 423 and spans above the support column 200. Specifically, the crossbar 422 can be detachably connected to the first vertical bar 421 and the second vertical bar 423. When installing the clamping ring 300 and the sealing gasket 600, the connection between the crossbar 422 and the first vertical bar 421 and the second vertical bar 423 can be disconnected. Alternatively, the crossbar 422 can be integrally fixed with the first vertical bar 421 and the second vertical bar 423 to further ensure the rigidity of the entire support clamp and increase its stability and reliability. A drive component 410 is disposed between the clamping ring 300 and the crossbar 422, with its two ends contacting the lower surface of the crossbar 422 and the upper surface of the clamping ring 300, respectively.

[0037] In some embodiments, the drive component 410 includes a hydraulic cylinder, the fixed end of which is disposed on the clamping ring 300, and the drive end of which is abutting against the crossbar 422.

[0038] Specifically, the driving component 410 can be a hydraulic cylinder. The fixed end of the hydraulic cylinder is located on the upper surface of the clamping ring 300, and the driving end extends upward and contacts the lower surface of the crossbar 422 of the frame 420. The crossbar 422 is firmly connected to the base 100 through the first vertical bar 421 and the second vertical bar 423 to form a rigid support structure. During operation: the hydraulic cylinder is controlled to extend its driving end upward, pressing against the lower surface of the crossbar 422. The crossbar 422, as a fixed fulcrum, provides a counterforce, thereby pushing the clamping ring 300 downward through the fixed end of the hydraulic cylinder, causing the clamping ring 300 to move axially downward along the support column 200, applying axial clamping force to the sealing gasket 600. With this configuration, the vertical lifting force is converted into a stable downward force on the clamping ring 300 through the lever-type force transmission mechanism formed by the hydraulic cylinder and the crossbar 422. The principle of reaction force is used to achieve efficient force transmission, ensuring the controllability and uniformity of the clamping force. Furthermore, by placing the fixed end of the hydraulic cylinder on the clamping ring 300, oil leakage from the hydraulic cylinder can prevent the sealing gasket 600 from being contaminated.

[0039] In some embodiments, the drive component 410 includes a cylinder or a linear motor, the fixed end of which is detachably mounted on the crossbar 422, and the drive end of which is abutted against the clamping ring 300.

[0040] Specifically, the driving component 410 can be a cylinder or a linear motor. The cylinder or linear motor is divided into a driving end and a fixed end. The fixed end is detachably set on the lower surface of the crossbar 422. The driving end is controlled to generate a downward displacement or thrust. With the crossbar 422 as a rigid reaction support point, the force is transmitted to the clamping ring 300, driving the clamping ring 300 to move axially along the support column 200 toward the base 100, thereby applying an axial clamping force to the sealing gasket 600 sleeved on the support column 200. This configuration, by detachably mounting the fixed end of the cylinder or linear motor on the lower surface of the crossbar 422, facilitates the assembly and disassembly of the clamping ring 300, enabling rapid assembly of the sealing gasket 600. The pressure structure formed by the crossbar 422 and the drive component 410 applies vertical pressure through the clamping ring 300 to the upper surface of the sealing gasket 600, effectively suppressing deformation of the sealing gasket 600 during storage and transportation caused by material creep or stress relaxation, and ensuring the dimensional stability of the sealing gasket 600.

[0041] In some embodiments, the drive component 410 includes a hydraulic jack, a mechanical jack, a pneumatic jack, a hydraulic cylinder, or a bolt jack.

[0042] In some embodiments, such as Figure 1 As shown, multiple support rods 500 are arranged at even intervals around the support column 200 in the circumferential direction.

[0043] With the above technical solution, the sealing gasket 600 has multiple flow channel holes circumferentially arranged around its center, and multiple support rods 500 are arranged circumferentially around the support column 200 at intervals, corresponding one-to-one with the flow channel holes on the sealing gasket 600. When installing the sealing gasket 600, the flow channel holes on the sealing gasket 600 are inserted into the corresponding support rods 500 to complete the installation of the sealing gasket 600. In this configuration, the circumferentially distributed support rods 500 form a ring array, creating a uniform circumferential constraint on the outer edge area of ​​the sealing gasket 600, eliminating local stress concentration, and effectively suppressing radial deformation or edge warping of the sealing gasket 600.

[0044] In some embodiments, the outer diameter of the base 100 and the clamping ring 300 is 100mm to 3000mm; and / or, the thickness of the base 100 and the clamping ring 300 is 3mm to 100mm.

[0045] Specifically, the outer diameters of the clamping ring 300 and the base 100 can be any size within the range of 100mm, 500mm, 1000mm, 1500mm, 2000mm, 2500mm, or 3000mm. The thicknesses of the base 100 and the clamping ring 300 can be any size within the range of 3mm, 10mm, 30mm, 50mm, 70mm, 90mm, or 100mm. The thickness of the base 100 and the clamping ring 300 refers to the thickness along the axial direction of the support column 200. The outer diameter and thickness of the base 100 and the clamping ring 300 can simultaneously meet the above-mentioned size ranges, or the outer diameter of the base 100 and the clamping ring 300 can individually meet the above-mentioned outer diameter size ranges, or the thickness of the base 100 and the clamping ring 300 can individually meet the above-mentioned thickness size ranges.

[0046] In some embodiments, the outer diameter of the clamping ring 300 is smaller than the outer diameter of the base 100. With this configuration, when the frame 420 is configured with a first vertical rod 421, a horizontal rod 422, and a second vertical rod 423 connected sequentially, the first vertical rod 421 and the second vertical rod 423 are respectively connected to the outer side of the base 100. If the outer diameter of the clamping ring 300 is smaller than the outer diameter of the base 100, the first vertical rod 421 and the second vertical rod 423 will not be obstructed by the periphery of the clamping ring 300, thus avoiding bending the relative positions of the first vertical rod 421 and the second vertical rod 423 to allow the larger outer diameter clamping ring 300 to pass through, thereby increasing the stability of the entire support fixture.

[0047] Furthermore, with the outer diameters of the clamping ring 300 and the base 100 adopting the aforementioned dimensions, the dimensions of the base 100 and the clamping ring 300 are adapted to the dimensions of the sealing gasket 600. The outer diameters of the base 100 and the clamping ring 300 fully cover the outer edge area of ​​the sealing gasket 600, and the thickness provides sufficient structural rigidity and stability. During operation: when the driving component 410 drives the clamping ring 300 to move towards the base 100, the clamping ring 300, with its appropriate outer diameter, can completely cover the gasket surface and apply a uniform clamping force, avoiding local stress concentration caused by insufficient clamping area; at the same time, the base 100 and the clamping ring 300, with their appropriate thickness, maintain small structural deformation during clamping, improving the overall structural stability of the support fixture and ensuring the stability of the clamping force transmission. This configuration, through optimized structural dimensions, allows the support clamp to accommodate sealing gaskets 600 of different specifications. While providing sufficient compression coverage, it maintains adequate structural rigidity, effectively preventing changes in the dimensions of the sealing gaskets 600 due to uneven compression or structural deformation.

[0048] The materials of the first vertical bar 421, the horizontal bar 422, and the second vertical bar 423 include stainless steel, steel, aluminum alloy or other metals, composite materials or engineering plastics, etc.

[0049] In some embodiments, such as Figure 1 As shown, the support column 200 includes a hollow support column 200. Specifically, the hollow support column 200 can be entirely hollow from its upper end face to its lower end face, meaning that the two end faces of the hollow support column 200 are directly connected, and any cross-section of the hollow support column 200 is annular; or the two end faces of the support column 200 have rigid structures, with only the central part of the support column 200 being hollow, meaning that part of the cross-section of the hollow support column 200 is annular, and part of the cross-section is entirely circular. This design effectively reduces the overall weight of the support clamp, and the hollow design allows the support column 200 to reduce material usage and improve portability while ensuring sufficient structural rigidity.

[0050] Furthermore, the outer diameter of the support column 200 is 100mm to 3000mm; and / or, the wall thickness of the support column 200 is 3mm to 100mm.

[0051] Specifically, the outer diameter of the support column 200 can be 100mm, 500mm, 1000mm, 1500mm, 2000mm, 2500mm, or 3000mm, or any size within this range. When the support column 200 is a hollow support column 200 with its upper and lower end faces connected, the wall thickness of the hollow support column 200 can be 3mm, 10mm, 30mm, 50mm, 70mm, 90mm, or 100mm, or any size within this range. Furthermore, the outer diameter and wall thickness of the support column 200 can simultaneously satisfy the aforementioned size ranges, or the outer diameter of the support column 200 can alone satisfy the aforementioned outer diameter size range, or the wall thickness of the support column 200 can alone satisfy the aforementioned thickness size range.

[0052] When the outer diameter and / or wall thickness of the support column 200 are as described above, the support column 200 is mounted on the base 100 for positioning and fitting the sealing gasket 600. Its outer diameter range is fully compatible with the inner hole dimensions of sealing gaskets 600 of different specifications, and its wall thickness range ensures that the support column 200 possesses sufficient structural strength and rigidity. The support column 200 with an appropriate outer diameter can form a precise fit with the inner hole of the gasket, providing a reliable radial positioning reference; simultaneously, the support column 200 with an appropriate wall thickness can maintain a small range of deformation when subjected to the axial pressure transmitted by the clamping ring 300, ensuring the stability of pressure transmission.
