Description

Technical Field

[0001] This application relates to the field of sealing technology, and in particular to an energy storage sealing assembly. Background Technology

[0002] Spring-storage seals are high-performance sealing structures with broad application prospects in ultra-high temperature, ultra-low temperature, corrosive media, and ultra-high pressure conditions.

[0003] The spring-storage sealing assembly includes an elastic jacket and a circumferential metal spring housed within the elastic jacket. Due to the significant difference in stiffness between the metal spring and the elastic jacket, under the same operating conditions, the metal spring, with its higher stiffness, experiences less deformation, while the elastic jacket, with its lower stiffness, undergoes greater deformation; the difference in deformation between the two is significant. Furthermore, the area of ​​the elastic jacket in contact with the metal spring is constrained by the spring, resulting in less deformation in this area; while the area of ​​the elastic jacket not in contact with the spring is unconstrained and experiences greater deformation. This leads to uneven deformation at different locations within the elastic jacket.

[0004] This uneven deformation reduces the sealing performance and lifespan of the spring energy storage seal assembly, hindering its application in complex and harsh working conditions. Summary of the Invention

[0005] This application provides an energy storage sealing assembly that can reduce uneven deformation of the energy storage sealing assembly.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] This application provides an energy storage sealing assembly, including an elastic jacket, a first elastic element and at least one second elastic element. The elastic jacket forms a closed ring, and a first end of the elastic jacket along its own axial direction has a first receiving groove. The first elastic element is disposed in the first receiving groove, and the first receiving groove is configured to contact a fluid medium. The elastic jacket is configured to seal against the element to be sealed circumferentially by the first elastic element or the fluid medium under the pressure of the first elastic element or the fluid medium.

[0008] The second elastic element is disposed on the sidewall of the second end of the elastic sleeve along its own axial direction and is configured to suppress the deformation of the elastic sleeve.

[0009] In one possible implementation, the elastic sleeve expands radially to both sides under the elastic force of the first elastic element or the pressure of the fluid medium to seal against the element to be sealed.

[0010] In one possible implementation, the second elastic element is disposed on at least one of the circumferential inner wall and the circumferential outer wall of the elastic sleeve.

[0011] In one possible implementation, the second elastic element is provided on both the inner and outer circumferential walls of the elastic sleeve, and the positions of each second elastic element in the axial direction of the elastic sleeve are matched with each other.

[0012] In one possible implementation, the second elastic element is wound around the elastic sleeve once in the circumferential direction.

[0013] In one possible implementation, the second end sidewall of the elastic sleeve is provided with a second receiving groove corresponding to the second elastic member. The opening of the second receiving groove is opened radially along the elastic sleeve, and the second elastic member is disposed in the second receiving groove through the opening of the second receiving groove.

[0014] As one possible implementation, the second elastic member and the second receiving groove are interference-fitted.

[0015] In one possible implementation, the second receiving groove is an annular groove surrounding the circumferential sidewall of the elastic jacket.

[0016] In one possible implementation, at least two second elastic elements are provided on the same circumferential sidewall of the elastic sleeve, and the second elastic elements located on the same circumferential sidewall of the elastic sleeve are spaced apart along the axial direction of the elastic sleeve.

[0017] In one possible implementation, at least one of the first elastic element and the second elastic element is a spring.

[0018] This application provides an energy-storing sealing assembly, including an elastic jacket, a first elastic element, and at least one second elastic element. The elastic jacket forms a closed shape, and a first receiving groove is provided at a first end along its own axial direction.

The second elastic element is disposed on the sidewall of a second end of the elastic jacket along its own axial direction and is configured to suppress deformation of the elastic jacket. Through the cooperation between the second elastic element and the sidewall of the second end of the elastic jacket, when the elastic jacket deforms, it is still constrained by the elastic force of the second elastic element and does not produce structural deformation.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In the absence of conflict, the following embodiments and features can be combined with each other.

[0037] In existing technologies, spring-energy-storing sealing assemblies include an elastic jacket and a circumferential metal spring housed within the elastic jacket. Because the stiffness of the metal spring and the elastic jacket differs significantly, under the same operating conditions, the metal spring, with its higher stiffness, experiences less deformation, while the elastic jacket, with its lower stiffness, undergoes greater deformation; the deformation difference between the two is significant. Furthermore, the area of ​​the elastic jacket in contact with the metal spring is constrained by the spring, resulting in less deformation in this area; while the area of ​​the elastic jacket not in contact with the metal spring is unconstrained, leading to greater deformation. This results in uneven deformation at different locations within the elastic jacket. This uneven deformation reduces the sealing performance and lifespan of the spring-energy-storing sealing assembly, hindering its application in complex and demanding operating conditions.

[0038] To overcome the deficiencies in the prior art, this application provides an energy storage sealing assembly, including an elastic jacket, a first elastic element, and at least one second elastic element. The elastic jacket forms a closed ring, and a first accommodating groove is provided at a first end along its own axial direction. The first elastic element is disposed within the first accommodating groove, and the first accommodating groove is configured to contact a fluid medium. The elastic jacket is constructed to seal against the component to be sealed circumferentially under the pressure of the first elastic element or the fluid medium. The second elastic element is disposed on the sidewall of the second end of the elastic jacket along its own axial direction and is configured to suppress deformation of the elastic jacket. Through the cooperation between the second elastic element and the sidewall of the second end of the elastic jacket, when the elastic jacket deforms, it is still constrained by the elastic force of the second elastic element and no structural deformation occurs.

[0039] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0040] This application provides an energy storage sealing assembly, including an elastic sleeve 110, a first elastic element 120 and at least one second elastic element 130. The elastic sleeve 110 forms a closed ring, and the first end of the elastic sleeve 110 along its own axial direction has a first receiving groove 1101. The first elastic element 120 is disposed in the first receiving groove 1101, and the first receiving groove 1101 is configured to contact a fluid medium. The elastic sleeve 110 is configured to seal against the circumferentially sealed member 140 of the elastic sleeve 110 under the pressure of the first elastic element 120 or the fluid medium.

[0041] The second elastic element 130 is disposed on the side wall of the second end of the elastic sleeve 110 along its own axial direction and is configured to suppress the deformation of the elastic sleeve 110.

[0042] Figure 1 This is a schematic diagram of the energy storage sealing assembly provided in the embodiments of this application; Figure 2A bottom view of the energy storage sealing assembly provided in the embodiments of this application; Figure 3 This is a top view of the energy storage sealing assembly provided in an embodiment of this application.

[0043] Specifically, such as Figures 1-3 As shown, this application provides an energy storage sealing assembly, including an elastic sleeve 110, a first elastic element 120, and a second elastic element 130.

[0044] like Figure 2 As shown, the elastic sleeve 110 forms a closed ring, and has an opening at the first end of the elastic sleeve 110 along its own axial direction. The opening is recessed away from the first end of the elastic sleeve 110, forming a first receiving groove 1101, a first lip 1102 and a second lip 1103.

[0045] The first elastic element 120 is disposed within the first receiving groove 1101. The first elastic element 120 is a closed annular element, such as a spring. Figure 1 As shown, the first elastic member 120 abuts against the first lip 1102 and the second lip 1103 on opposite sides along its own radial direction.

[0046] The first end of the elastic sleeve 110 is in contact with the fluid medium. Under the combined action of the fluid medium and the first elastic element 120, the first lip 1102 and the part to be sealed 140 are sealed together. It should be noted that, for ease of understanding, the part to be sealed 140 in this embodiment is a cylinder, and the shape of the part to be sealed 140 is not limited to a cylinder.

[0047] At least one second elastic element 130 is provided on the side wall of the second end of the elastic sleeve 110 along its own axial direction. The second elastic element 130 can be provided on the inner circumferential side of the second end of the elastic sleeve 110 or on the outer circumferential side of the second end of the elastic sleeve 110. It is easy to understand that when there are multiple second elastic elements 130, the second elastic elements 130 can be provided on both sides of the second end of the elastic sleeve 110.

[0048] The second elastic element 130 can suppress the deformation of the elastic sleeve 110 according to its own elastic force characteristics. That is, when the elastic sleeve 110 expands radially, the second elastic element 130 is compressed. At this time, under the elastic force of the second elastic element 130, the deformation of the second elastic element 130 changes with the elastic sleeve 110, thereby resisting the expansion deformation of the elastic sleeve 110.

[0049] When the elastic sleeve 110 contracts radially, the pressure on the second elastic element 130 decreases. At this time, the elastic force of the second elastic element 130 will cause the second elastic element 130 to expand radially and expand accordingly with the contraction of the elastic sleeve 110, so as to counteract the contraction deformation of the elastic sleeve 110.

[0050] As one possible implementation, the elastic jacket 110 expands radially to both sides under the action of the elastic force of the first elastic member 120 or the pressure of the fluid medium, so as to seal against the member to be sealed 140.

[0051] For details, see Figure 1 The first elastic element 120 is disposed in the first receiving groove 1101 on the elastic sleeve 110. The first elastic element 120 abuts against the first lip 1102 and the second lip 1103 on both sides along its own radial direction. The first lip 1102 is located between the first elastic element 120 and the member to be sealed 140, and the first lip 1102 abuts against the first elastic element 120 and the member to be sealed 140.

[0052] When the energy storage seal is working and the fluid medium in the system is in a stable state, the first elastic element 120 uses its own elastic force to move the first lip 1102 closer to the side of the component to be sealed 140, and the first lip 1102 seals the component to be sealed 140.

[0053] When the pressure of the fluid medium in the system increases, the fluid medium fills the first receiving groove 1101 of the elastic jacket 110. Under the combined action of the pressure of the fluid medium and the elastic force of the first elastic element 120, the first lip 1102 moves closer to the object to be sealed 140, so as to complete the sealing of the object to be sealed 140 by the first lip 1102.

[0054] Optionally, the second elastic element 130 is disposed on at least one of the circumferential inner wall and the circumferential outer wall of the elastic sleeve 110.

[0055] When the second elastic element 130 is disposed on the inner circumferential sidewall of the elastic sleeve 110, the elastic sleeve 110 will expand radially outward in a high-temperature working environment. The second elastic element 130 disposed on the inner circumferential sidewall of the elastic sleeve 110 is compressed by the expansion of the elastic sleeve 110, and the resulting elastic force causes the second elastic element 130 to contract to resist the expansion deformation of the elastic sleeve 110 so that the elastic sleeve 110 remains deformed and stable.

[0056] It is easy to understand that the second elastic element 130 is disposed on the circumferential inner wall of the elastic sleeve 110. When the temperature of the working environment decreases, the elastic sleeve 110 will shrink and deform inward along its own radial direction. At this time, the compression of the second elastic element 130 disposed on the circumferential inner wall of the elastic sleeve 110 becomes smaller, and the corresponding elastic force will change. The internal elastic force of the second elastic element 130 causes the second elastic element 130 to expand and deform relatively on the axial inner wall of the elastic sleeve 110, thereby ensuring the deformation stability of the elastic sleeve 110.

[0057] When the second elastic element 130 is disposed on the circumferential outer wall of the elastic sleeve 110, the elastic sleeve 110 will expand radially outward in a high-temperature working environment. The second elastic element 130 disposed on the circumferential outer wall of the elastic sleeve 110 is forced to expand, and the resulting elastic force causes the second elastic element 130 to contract to counteract the expansion deformation of the elastic sleeve 110, so as to keep the elastic sleeve 110 stable in deformation.

[0058] Correspondingly, the second elastic element 130 is disposed on the circumferential outer wall of the elastic sleeve 110. When the temperature of the working environment decreases, the second elastic element 130 will shrink radially inward. At this time, the compression of the second elastic element 130 disposed on the circumferential outer wall of the elastic sleeve 110 decreases, and the corresponding elastic force will also change. The internal elastic force of the second elastic element 130 causes the second elastic element 130 to expand to ensure the stability of the elastic sleeve 110.

[0059] One possible implementation is that a second elastic element 130 is provided on both the inner and outer circumferential walls of the elastic sleeve 110, and the positions of each second elastic element 130 in the axial direction of the elastic sleeve 110 are matched with each other.

[0060] Still Figure 1 As shown, in this embodiment, there are two second elastic elements 130, which are respectively disposed on the inner circumferential sidewall and the outer circumferential sidewall of the elastic sleeve 110. The positions of the two second elastic elements 130 on the inner and outer circumferential sidewalls of the elastic sleeve 110 correspond to each other, that is, the two second elastic elements 130 are at the same height along the axial direction of the elastic sleeve 110 on the inner and outer circumferential sidewalls of the elastic sleeve 110.

[0061] At this time, when the operating temperature of the energy storage sealing assembly rises, the second end of the elastic sleeve 110 undergoes an expansion deformation that increases radially outward along the elastic sleeve 110 itself. The second elastic element 130, which is provided on the inner circumferential sidewall of the elastic sleeve 110, is compressed, and the internal elastic force of the second elastic element 130 on the inner circumferential sidewall of the elastic sleeve 110 increases, causing the second elastic element 130 on the inner circumferential sidewall of the elastic sleeve 110 to expand circumferentially to counteract the deformation of the elastic sleeve 110 on the inner circumferential sidewall.

[0062] At the same time, the second elastic element 130 provided on the outer circumferential wall of the elastic sleeve 110 is forced to expand, and the internal elastic force of the second elastic element 130 on the outer circumferential wall of the elastic sleeve 110 increases, causing the second elastic element 130 on the outer circumferential wall of the elastic sleeve 110 to contract along its own circumferential direction to counteract the deformation of the elastic sleeve 110 at the outer circumferential wall.

[0063] By setting two second elastic elements 130 on the inner and outer circumferential walls of the elastic sleeve 110, when the elastic sleeve 110 deforms, the second elastic elements 130 change with the deformation of the elastic sleeve 110 by relying on their own elastic force, thereby suppressing the deformation of the elastic sleeve 110 and ensuring the structural stability of the sealing components inside the system.

[0064] Possibly, the second elastic element 130 is arranged around the elastic sleeve 110 in the circumferential direction.

[0065] Figure 2 This is a bottom view of the energy storage sealing assembly provided in an embodiment of this application.

[0066] Combination Figure 1 and Figure 2 In this embodiment, two second elastic elements 130 are arranged around the inner and outer circumferential walls of the elastic sleeve 110 along its own axial direction. The two second elastic elements 130 are closed rings and abut against the inner and outer circumferential walls of the elastic sleeve 110.

[0067] Optionally, a second receiving groove 1104 corresponding to the second elastic member 130 is provided on the second end side wall of the elastic sleeve 110. The groove opening of the second receiving groove 1104 is opened radially along the elastic sleeve 110, and the second elastic member 130 is disposed in the second receiving groove 1104 through the groove opening of the second receiving groove 1104.

[0068] like Figure 1 As shown, the elastic sleeve 110 in this embodiment includes a second receiving groove 1104. The second receiving groove 1104 is disposed on the side wall of the second segment of the elastic sleeve 110 along its own axial direction. The second receiving groove 1104 has a slot that is opened radially along the elastic sleeve 110, and the second elastic member 130 is disposed in the second receiving groove 1104 through the slot.

[0069] It should be noted that the second receiving groove 1104 and the second elastic element 130 are correspondingly provided. When there is only one second elastic element 130, and the second elastic element 130 is located on the inner wall of the elastic sleeve 110, then the second receiving groove 1104 is only provided on the inner wall of the elastic sleeve 110. Correspondingly, when one second elastic element 130 is located on the outer wall of the elastic sleeve 110, then the second receiving groove 1104 is only provided on the outer wall of the elastic sleeve 110.

[0070] There is still a feasible implementation method where multiple second elastic elements 130 are present in the energy storage sealing assembly, specifically, as shown in... Figure 1As shown, the energy storage sealing assembly in this embodiment includes two second elastic elements 130, and the two second elastic elements 130 are respectively disposed on the inner circumferential sidewall and the outer circumferential sidewall of the elastic sleeve 110 along its own axial direction. At this time, the inner circumferential sidewall and the outer circumferential sidewall of the elastic sleeve 110 are both provided with second receiving grooves 1104.

[0071] It should be noted that the number of the second elastic element 130 in this embodiment is not specifically limited. A reasonable number of the second elastic element 130 can be selected according to the actual application conditions of the energy storage sealing assembly and the deformation of the elastic sleeve 110. After determining the setting position of the second elastic element 130, the second receiving groove 1104 can be set accordingly.

[0072] Possibly, there is an interference fit between the second elastic element 130 and the second receiving groove 1104.

[0073] Specifically, the second receiving groove 1104 is disposed on the elastic sleeve 110, and the second elastic member 130 and the second receiving groove 1104 are interference-fitted, that is, the second elastic member 130 and the elastic sleeve 110 are interference-fitted.

[0074] Optionally, the second receiving groove 1104 is an annular groove surrounding the circumferential sidewall of the elastic sleeve 110.

[0075] In one possible implementation, at least two second elastic elements 130 are provided on the same circumferential sidewall of the elastic sleeve 110, and the second elastic elements 130 located on the same circumferential sidewall of the elastic sleeve 110 are spaced apart along the axial direction of the elastic sleeve 110.

[0076] The energy storage sealing assembly provided in this embodiment includes at least two second elastic elements 130. Furthermore, the second elastic elements 130 in this embodiment can be disposed on the same inner wall of the elastic sleeve 110. When one second elastic element 130 cannot meet the design requirements, or when the second end of the elastic sleeve 110 deforms significantly in a complex working environment, multiple second elastic elements 130 can be used.

[0077] Optionally, at least one of the first elastic element 120 and the second elastic element 130 is a spring.

[0078] Specifically, in this embodiment, both the first elastic element 120 and the second elastic element 130 are springs, and the cross-section of the springs can be selected as follows: Figure 1 The circle shown can also be an ellipse, rectangle, etc. It should be noted that when both the first elastic element 120 and the second elastic element 130 are springs, the cross-sectional shapes of the first elastic element 120 and the second elastic element 130 can be the same or different, as long as the first elastic element 120 and the second elastic element 130 meet the design requirements.

[0079] Optionally, the energy storage sealing assembly also includes a housing 150, which is disposed on the outside of the elastic sleeve 110. The second lip 1103 of the elastic sleeve 110 abuts against the inner wall of the housing 150. The elastic sleeve 110 is clamped between the object to be sealed 140 and the housing 150, so that the compressive force on both sides of the elastic sleeve 110 is balanced. The elastic sleeve 110 is supported on both sides by the object to be sealed 140 and the housing 150, respectively, so that the energy storage sealing assembly can withstand greater fluid medium pressure.

[0080] The outer casing 150 includes an annular sleeve 1502 and a first stop 1501 and a second stop 1503 respectively disposed at both ends of the annular sleeve 1502. The second stop 1503 is opposite to the first receiving groove 1101 and has a fluid flow gap with the first receiving groove 1101. The first stop 1501 is opposite to the second end of the elastic sleeve 110.

[0081] When the fluid medium pressure is high, the first lip 1102 is tightly fitted with the part to be sealed 140, and the second lip 1103 is tightly fitted with the annular sleeve 1502 to seal the fluid medium, and the first stop 1501 does not come into contact with the fluid medium; when the fluid medium pressure is low, the first lip 1102 is tightly fitted with the part to be sealed 140, and the second lip 1103 is tightly fitted with the annular sleeve 1502, and under the compression of the elastic restoring force of the first elastic element 120, the fit between the first lip 1102 and the part to be sealed 140, and the second lip 1103 and the annular sleeve 1502 is even tighter, and the first stop 1501 also does not come into contact with the fluid medium.

[0082] When the fluid medium pressure is low, the second retaining edge 1503 can effectively prevent the elastic jacket 110 from axially displacing towards the fluid medium flow direction; when the fluid medium pressure is high, the first retaining edge 1501 can effectively prevent the elastic jacket 110 from axially displacing away from the fluid medium flow direction. The arrangement of the first retaining edge 1501 and the second retaining edge 1503 restricts the axial movement of the elastic jacket 110, further improving the stability of the elastic energy storage sealing assembly.

[0083] This application provides an energy storage sealing assembly, including an elastic jacket 110, a first elastic element 120, and at least one second elastic element 130. The elastic jacket 110 forms a closed annulus, and a first receiving groove 1101 is provided at a first end along its own axial direction. The first elastic element 120 is disposed within the first receiving groove 1101, and the first receiving groove 1101 is configured to contact a fluid medium. Under the pressure of the first elastic element 120 or the fluid medium, the elastic jacket 110 seals against the circumferentially sealed component 140. The second elastic element 130 is disposed on the sidewall of the second end of the elastic jacket 110 along its own axial direction, and can suppress the deformation of the elastic jacket 110. Through the elastic force of the second elastic element 130 disposed on the sidewall of the second end of the elastic jacket 110 along its own axial direction, the second elastic element 130 changes with the deformation of the elastic jacket 110, achieving the effect of stabilizing the elastic jacket 110, making the internal structure of the sealing system more stable, thereby improving the sealing performance of the system.
