Description

Technical Field

[0001] The present invention relates to a sealing element for high-pressure connection, a sealing unit, and a system for electrolysis. Background Technology

[0002] Currently, there are many different solutions available for designing sealing elements. The demand for innovative and robust sealing elements continues to increase due to the growing number of systems used in electrolysis and the increasing requirements for quality and output.

[0003] In factory engineering, the continuous pursuit of efficiency improvements to reduce energy consumption, coupled with increasingly fierce competition, has led to greater cost pressures, resulting in higher demand for more cost-effective and efficient system components. Summary of the Invention

[0004] An improved sealing element can be advantageously provided through embodiments of the present invention. The invention is defined in the independent claims. Advantageous improvements of the invention arise from the dependent claims and the description below.

[0005] One advantage of the sealing element having the features of claim 1 is that it can be activated by ambient pressure by means of a specific arrangement of the first side relative to the second side, thereby preventing leakage in high-pressure applications, even when the sealing element is compressed between the two components. By means of the arrangement of the first portion relative to the second portion, a gap to spacing height ratio of at most 0.3 can be achieved during use to create a seal.

[0006] This is achieved according to the invention, wherein the sealing element for high-pressure connection includes a first portion and a second portion, wherein the first portion is configured to place the sealing element in the gap, wherein a first side of the first portion is configured to be substantially orthogonal to a second side of the second portion, wherein the second portion has a third side, wherein the second portion is specifically designed to press the third side against the gap to be sealed when increased ambient pressure is applied to the second side.

[0007] By utilizing the cross-section of the sealing element derived from the first side of the first portion and / or the second side of the second portion, it is possible to activate the sealing element in a compressed state when ambient pressure is applied, thereby increasing the sealing performance of the sealing element or the gap to be sealed when the gap to be sealed is impacted by a high-pressure fluid. The sealing element preferably has two portions, which are arranged on the sealing element in the form of a web or similar material. The first web is preferably arranged substantially orthogonal to the second web. In this way, the first portion having the first side and the second portion having the second side are arranged substantially orthogonal to each other. In this context, substantially orthogonal to each other should be understood to specifically cover variations of ±45°, particularly covering production-related tolerances. The first portion forms a base for the sealing element, which can be inserted into the spacer of the assembly to enable the sealing element to be fixed in a fixed position relative to this assembly. The second portion of the sealing element protrudes from the spacer in such a way that this second portion is supported on another assembly. In this way, gaps that may arise between the assembly and the other assembly can be sealed by means of the sealing element. Preferably, pressure is applied to the second side of the second part so that the third side is pressed against the gap to be sealed.

[0008] The dependent claims set forth preferred improvements of the invention.

[0009] The first and second sides preferably have an intersection point, wherein the third side has at least partially a contour around the intersection point, specifically a curved shape.

[0010] One advantage of this embodiment is that the sealing performance of the sealing element can be further increased because a larger contact surface is formed between the sealing element and the assembly when the sealing element is under pressure. For example, the area covering the gap can be enlarged. Furthermore, the profile can have any shape or form. Preferably, the profile can be curved.

[0011] The second and third sides are preferably connected to each other by means of rounded corners.

[0012] One advantage of this implementation is that the contact surface between the sealing element and the other component is increased, thus improving the overall sealing performance or increasing the maximum pressure.

[0013] The first length of the first side and the second length of the second side preferably have a length ratio between 0.7 and 1.3.

[0014] One advantage of this implementation is that, surprisingly, it is possible to establish that the sealing performance is greatest at this length ratio, and specifically, the possible limit of the pressure is at most 80 bar.

[0015] Furthermore, preferably, the first portion has a fourth side, wherein the first thickness between the first side and the fourth side and the second thickness between the second side and the third side have a thickness ratio between 0.5 and 1.2.

[0016] One advantage of this embodiment is that, by means of the thickness ratio, a relatively large gap to spacing height ratio (up to 0.3) can be maintained substantially sealed. The first and fourth sides are preferably formed to be opposite each other on the first portion, and the second and third sides are preferably formed to be substantially opposite each other on the second portion.

[0017] The first part preferably has two molded parts, which are specifically designed to secure the sealing element in the spacer.

[0018] One advantage of this embodiment is that the assembly process of another component on the assembly is simplified because the sealing element is held securely in or between the first component by means of the molding material.

[0019] The sealing element preferably has a substantially continuous profile in order to form a ring.

[0020] One advantage of this implementation is that the variable gap between components can be corrected over the entire contour of the sealing unit by means of the sealing element.

[0021] Another aspect of the present invention relates to a sealing unit having:

[0022] -First component,

[0023] -Second component,

[0024] -A sealing element as described above and below, wherein the sealing element is specifically designed to substantially prevent fluid from flowing through the gap between the first component and the second component.

[0025] One advantage of this embodiment is that the sealing element can seal the gap between the first and second components, a seal that an O-ring or similar device might not be able to achieve. Here, the sealing element between the components can, specifically, self-seal under high pressure, as the pressure applied to the sealing element increases its sealing performance.

[0026] Preferably, the height ratio between the height of the gap and the height of the interval is at most 0.3.

[0027] One advantage of this implementation is that, specifically, a larger gap can be sealed under high pressure by means of the proposed sealing element.

[0028] Another aspect relates to a system for electrolysis having sealing elements as described above and below, and / or sealing units as described above and below.

[0029] Furthermore, it should be noted that the term "unit" in this document should similarly be understood in a broad sense, and includes the configuration of individual units in one component or the configuration of individual units in multiple components, wherein the corresponding sub-units need not be located in one place in the system, but may be distributed throughout the system.

[0030] All disclosures made above and below in the context of one aspect of the invention are equally applicable to all other aspects of the invention. Attached Figure Description

[0038] like Figure 1 As shown, the first side 18 and the second side 20 preferably have an intersection point 26. The third side 22 preferably has at least partially a contour 28 surrounding the intersection point 26. The center of the contour 28 is preferably at the same location as the intersection point 26. The second side 20 and the third side 22 are preferably connected to each other by means of a rounded corner 30, which specifically forms the tip of the second part 14.
