[0042] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used only for explanation of the present application, and cannot be understood as a limitation of the present application.

[0043] The sealing gasket 10 according to the embodiments of the present application is described below with reference to the drawings.

[0044] Referring to Figures 2-5 , the sealing gasket 10 according to the first aspect of the present application comprises: a metal skeleton sheet layer 1, for example, the metal skeleton sheet layer 1 can be an iron sheet layer, a copper sheet layer or an aluminum sheet layer. The metal skeleton sheet layer 1 has opposite first and second faces 12 and 13 in the thickness direction thereof, and the metal skeleton sheet layer 1 has a convex 14 protruding from the first face 12 in the direction from the second face 13 to the first face 12. For example, the convex 14 can be located in the middle region of the metal skeleton sheet layer 1, and the convex 14 can also be located in the edge region of the metal skeleton sheet layer 1 and include the radial outer edge of the metal skeleton sheet layer 1.

[0045] In the process of abutting against the two abutting members, the sealing end face of one of the abutting members can abut against the side of the convex 14 away from the first face 12, and the sealing end face of the other abutting member can abut against the second face 13, so that in the process of abutting against the two abutting members, the sealing gasket 10 has a large deformation space in the thickness direction thereof, so that the metal skeleton sheet layer 1 has a large amount of deformation, and the sealing gasket 10 has a large elastic energy after the two abutting members are connected together, thereby reliably abutting the first and second faces 12 and 13 of the metal skeleton sheet layer 1 against the corresponding sealing end faces, ensuring the reliability of the pipe connection assembly 100 and ensuring the sealing effect of the pipe connection assembly 100.

[0046] Moreover, compared with the technical solution of "generating a sealing force by deforming a metal gasket by setting a convex tooth structure on the sealing end face of the abutting member", since the sealing gasket 10 in the present application can have a large elastic energy after the two abutting members are connected together, it is not necessary to set a convex tooth structure on the sealing end face of the abutting member, so that the sealing end face of the abutting member can be set as a flat surface, which can reduce the processing difficulty of the abutting member, reduce the production cost of the abutting member, and reduce the production cost of the pipe connection assembly 100, compared with setting a convex tooth structure on the sealing end face of the abutting member.

[0047] For example, referring to Figure 2 , the metal skeleton sheet layer 1 can be in the form of a circular ring, and the metal skeleton sheet layer 1 defines an avoidance flow-through opening 11, and when the abutting member is a pipeline, the two abutting members can be connected through the avoidance flow-through opening 11 when they are abutted against each other.

[0048] According to the sealing gasket 10, the convex 14 is arranged on the metal framework sheet layer 1, when the sealing gasket 10 is arranged between two abutting pieces for sealing, the sealing gasket 10 has a large deformation space in the thickness direction, the metal framework sheet layer 1 has a large deformation amount, the sealing gasket 10 has a large rebound energy after the two abutting pieces are connected together, so that the first surface 12 and the second surface 13 of the metal framework sheet layer 1 are reliably abutted on the corresponding sealing end surfaces, the reliability of the pipe connection assembly 100 is ensured, and the sealing effect of the pipe connection assembly 100 is ensured.

[0049] Referring to Figures 2-5 According to some embodiments of the utility model, the sealing gasket 10 further comprises: a sealing function sheet layer 2, the sealing function sheet layer 2 is two, and the two sealing function sheet layers 2 are connected on both sides in the thickness direction of the metal framework sheet layer 1. For example, the sealing function sheet layer 2 can be a rubber layer, and the sealing function sheet layer 2 can be a silica gel layer.

[0050] When it is needed to seal the gap between the two abutting pieces connected by the sealing gasket 10, the sealing gasket 10 can be clamped between the sealing end surfaces of the two abutting pieces needing to be sealed, and then the two abutting pieces are abutted, and then the two abutting pieces are connected together.

[0051] When the sealing end surfaces of the two abutting pieces needing to be sealed are both flat surfaces, the two abutting pieces can extrude and deform the sealing function sheet layer 2, seal the gap between the two abutting pieces, and ensure the reliability of the sealing effect.

[0052] When at least one of the sealing end surfaces of the two abutting pieces needing to be sealed is a curved surface (that is, at least one sealing end surface has a concave or convex defect), in the process of abutting the two abutting pieces, the metal framework sheet layer 1 can be extruded and deformed, because the metal framework sheet layer 1 has good elasticity, the metal framework sheet layer 1 has a large rebound energy under the action of the deformation force driven by the metal framework sheet layer 1, so that a part of the metal framework sheet layer 1 can abut the sealing function sheet layer 2 on one side in the thickness direction on one sealing end surface, and another part of the metal framework sheet layer 1 can abut the sealing function sheet layer 2 on the other side in the thickness direction on the other sealing end surface, so that the sealing gasket 10 maintains good contact with the two sealing end surfaces, the sealing effect of the sealing gasket 10 on the gap between the two abutting pieces is good, and the reliability of the sealing effect is ensured.

[0053] Moreover, since the sealing function sheet layer 2 has good deformation ability, when the metal framework sheet layer 1 abuts against the sealing end face, the sealing function sheet layer 2 can generate large deformation, so that the sealing function sheet layer 2 can fully fill the gap between the metal framework sheet layer 1 and the sealing end face. In this way, the machining precision of the sealing end face does not have to be set to be high, the machining process difficulty of the butt joint piece can be reduced, the production efficiency of the butt joint piece can be improved, and the production cost of the butt joint piece can be reduced.

[0054] With reference to Figure 3 According to some embodiments of the present application, the convex envelope 14 includes the radial outer edge of the metal framework sheet layer 1, that is, the convex envelope 14 is arranged at the edge of the metal framework sheet layer 1. In this way, the number of bending inflection points on the metal framework sheet layer 1 can be reduced, the machining process difficulty of the metal framework sheet layer 1 can be reduced, the production efficiency of the metal framework sheet layer 1 can be improved, and the production cost of the metal sheet layer can be reduced.

[0055] With reference to Figure 3 In some embodiments of the present application, the area of the metal framework sheet layer 1 except the convex envelope 14 is a main body part 15, the convex envelope 14 includes a first ring body 141 and a second ring body 142, the first ring body 141 is connected to the radial outer side of the main body part 15, and the second ring body 142 is connected to the radial outer side of the first ring body 141.

[0056] In the thickness direction of the metal framework sheet layer 1, the surface of the main body part 15 away from the second ring body 142 is a first connecting surface 151, the surface of the second ring body 142 away from the main body part 15 is a second connecting surface 1421, the distance between the first connecting surface 151 and the second connecting surface 1421 in the thickness direction of the metal framework sheet layer 1 is an abutting distance L1, and the abutting distance L1 is greater than the thickness L2 of the metal framework sheet layer 1. For example, the thickness L2 of the metal framework sheet layer 1 can be 0.2mm, 0.21mm, 0.22mm, 0.23mm, 0.24mm, 0.25mm, 0.26mm, 0.27mm, 0.28mm, 0.29mm, or 0.3mm.

[0057] In the process of abutting against each other, the sealing end face of one of the butt joint pieces can abut against the first connecting surface 151, the sealing end face abutting against the first connecting surface 151 is a first sealing end face, and the sealing end face of the other butt joint piece can abut against the second connecting surface 1421, the sealing end face abutting against the second connecting surface 1421 is a second sealing end face.

[0058] The stop distance is set to be greater than the thickness L2 of the metal framework sheet layer 1, the first sealing end surface contacts the first connecting surface 151, the second sealing end surface contacts the second connecting surface 1421, and the two connecting pieces do not apply force to the sealing gasket 10, so that there is a certain gap between the surface of the main body 15 away from the first connecting surface 151 and the second sealing end surface, so that there is a certain gap between the surface of the second ring body 142 away from the second connecting surface 1421 and the first sealing end surface, so that the second ring body 142 has a certain space in the thickness direction of the metal framework sheet layer 1, so that the main body 15 has a certain space in the thickness direction of the metal framework sheet layer 1, so that the metal framework sheet layer 1 has a certain deformation space, so that the sealing gasket 10 has enough elastic energy after the two connecting pieces are connected together, and the first surface 12 and the second surface 13 of the metal framework sheet layer 1 are reliably stopped on the corresponding sealing end surface, ensuring the reliability of the pipe connection assembly 100 and ensuring the sealing effect of the pipe connection assembly 100.

[0059] For example, when the metal framework sheet layer 1 has sealing functional sheet layers 2 on both sides in the thickness direction, in the process of stopping the two connecting pieces, the first sealing end surface can be stopped on the sealing functional sheet layer 2 connected to the first connecting surface 151, and the surface of the sealing functional sheet layer 2 stopped by the first end surface 32 is the first stop surface 21; the second sealing end surface can be stopped on the sealing functional sheet layer 2 connected to the second connecting surface 1421, and the surface of the sealing functional sheet layer 2 stopped by the second end surface 42 is the first stop surface 21.

[0060] The stop distance is set to be greater than the thickness L2 of the metal framework sheet layer 1, the first sealing end surface contacts the first connecting surface 151, the second sealing end surface contacts the second connecting surface 1421, and the two connecting pieces do not apply force to the sealing gasket 10, so that there is a certain gap between the surface of the main body 15 away from the first connecting surface 151 and the second sealing end surface, so that there is a certain gap between the surface of the second ring body 142 away from the second connecting surface 1421 and the first sealing end surface, so that the second ring body 142 has a certain space in the thickness direction of the metal framework sheet layer 1, so that the main body 15 has a certain space in the thickness direction of the metal framework sheet layer 1, so that the metal framework sheet layer 1 has a certain deformation space, so that the sealing gasket 10 has enough elastic energy after the two connecting pieces are connected together, and the first surface 12 and the second surface 13 of the metal framework sheet layer 1 are reliably stopped on the corresponding sealing end surface, ensuring the reliability of the pipe connection assembly 100 and ensuring the sealing effect of the pipe connection assembly 100.

[0061] Referring to Figure 3 and Figure 5In some embodiments of the utility model, first connecting surface 151 and second connecting surface 1421 are parallel to each other. In the process of abutting against two butt joints, the contact area of first connecting surface 151 and first sealing end face can be made larger, the sealing effect between sealing gasket 10 and first sealing end face can be made better, the contact area of second connecting surface 1421 and second sealing end face can be made larger, the sealing effect between sealing gasket 10 and second sealing end face can be made better, and the sealing performance of sealing gasket 10 can be improved.

[0062] For example, when the two sides of the metal framework sheet layer 1 in the thickness direction are provided with the sealing function sheet layer 2, the first abutting surface 21 and the second abutting surface 22 can be made parallel to each other, the contact area of the first abutting surface 21 and the first sealing end face can be made larger in the process of abutting against two butt joints, the sealing effect between the sealing gasket 10 and the first sealing end face can be made better, the contact area of the second abutting surface 22 and the second sealing end face can be made larger, the sealing effect between the sealing gasket 10 and the second sealing end face can be made better, and the sealing performance of the sealing gasket 10 can be improved.

[0063] Referring to Figure 3 In some embodiments of the utility model, the ratio of the abutting distance L1 to the thickness L2 of the metal framework sheet layer 1 is greater than or equal to 1.5 and less than or equal to 3.5. For example, the abutting distance L1 and the thickness L2 of the metal framework sheet layer 1 can be 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.3, 3.3, 3.4, 3.5.

[0064] The greater the ratio of the abutting distance L1 to the thickness L2 of the metal framework sheet layer 1, the greater the abutting distance L1, the greater the range of movement of the metal framework sheet layer 1 after being compressed, and the greater the rebound energy of the sealing gasket 10 after the two butt joints are connected together. The smaller the ratio of the abutting distance L1 to the thickness L2 of the metal framework sheet layer 1, the smaller the abutting distance L1, and the smaller the space occupied by the metal framework sheet layer 1 in the thickness direction, and the smaller the change degree of the metal framework sheet layer 1 in the radial direction after being compressed.

[0065] By setting the ratio of the abutting distance L1 to the thickness L2 of the metal framework sheet layer 1 to be greater than or equal to 1.5 and less than or equal to 3.5, the metal framework sheet layer 1 can have a larger range of movement after being compressed while being relatively compact as a whole, the sealing gasket 10 can have both compactness and reliability, and the butt joints can be arranged relatively compactly.

[0066] Referring to Figure 3In some embodiments of the utility model, the width of first ring body 141 in its radial direction is connection width L3, the ratio of stop distance L1 and connection width L3 is greater than or equal to 0.2 and less than or equal to 0.45. For example, the ratio of stop distance L1 and connection width L3 can be 0.2, 0.21, 0.22, 0.23, 0.24, 0.25, 0.26, 0.27, 0.28, 0.29, 0.3, 0.31, 0.32, 0.33, 0.34, 0.35, 0.36, 0.37, 0.38, 0.39, 0.4, 0.41, 0.42, 0.43, 0.44, 0.45. Specifically, connection width L3 can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm.

[0067] The greater the ratio of stop distance L1 and connection width L3, the greater the stop distance L1, the greater the range of the metal skeleton sheet layer 1 after being compressed, and the greater the rebound energy of the gasket 10 after the two abutting pieces are connected together. The smaller the ratio of stop distance L1 and connection width L3, the smaller the stop distance L1, the smaller the space occupied by the metal skeleton sheet layer 1 in its thickness direction, and the smaller the change degree of the metal skeleton sheet layer 1 in the radial direction after being compressed.

[0068] By setting the ratio of stop distance L1 and connection width L3 to be greater than or equal to 0.2 and less than or equal to 0.45, the metal skeleton sheet layer 1 can have a larger movable range after being compressed, and the metal skeleton sheet layer 1 as a whole is more compact, so that the gasket 10 has both compactness and reliability, and the abutting pieces can be arranged more compactly.

[0069] According to some optional embodiments of the utility model, the metal skeleton sheet layer 1 and the sealing function sheet layer 2 are integrally formed, and the processing technology of integral forming is double material injection molding. In this way, the connection between the metal skeleton sheet layer 1 and the sealing function sheet layer 2 is more reliable, the sealing effect between the metal skeleton sheet layer 1 and the sealing function sheet layer 2 is better, and the sealing property of the gasket 10 is effectively improved.

[0070] Referring to Figure 1 , Figure 4 and Figure 5According to a second aspect embodiment of the present invention, a pipe assembly 100 includes: a first connector 30, a second connector 40, and a sealing gasket 10 according to a first aspect embodiment of the present invention. The first connector 30 defines a first flow channel 31, and one end face of the first connector 30 in the flow direction of the first flow channel 31 is a first end face 32. The second connector 40 is connected to the first connector 30, defines a second flow channel 41, and one end face of the second connector 40 in the flow direction of the second flow channel 41 is a second end face 42. The sealing gasket 10 is sandwiched between the first end face 32 and the second end face 42. For example, the metal skeleton sheet 1 can be annular, and the metal skeleton sheet 1 defines an avoidance flow port 11, through which the first flow channel 31 and the second flow channel 41 communicate with each other.

[0071] According to the pipe assembly 100 of this utility model, by setting the sealing gasket 10, the reliability of the seal between the first end face 32 and the second end face 42 can be guaranteed, so that the machining accuracy of the first end face 32 does not need to be set too high, and the machining accuracy of the second end face 42 does not need to be set too high, which can reduce the production cost of the first connector 30, reduce the production cost of the second connector 40, and reduce the production cost of the pipe assembly 100.

[0072] Reference Figure 3 In some embodiments of this utility model, the first connector 30 further includes a first connecting portion 33, which is connected to the outer peripheral side of the first end face 32 and defines a connecting cavity 331. The second connector 40 passes through the connecting cavity 331. The radially outer side of the first connecting portion 33 has an external thread. The pipe assembly 100 further includes a connecting sleeve 50, which is connected to the outer peripheral side of the second connector 40 and is rotatable relative to the second connector 40. The connecting sleeve 50 has an internal thread that matches the external thread of the first connecting portion 33, and the internal thread is coaxially arranged with the sealing gasket.

[0073] The threaded connection allows the first connector 30 and the second connector 40 to be connected and fixed securely, ensuring a reliable structure. The internal thread is coaxial with the sealing gasket. When the first connector 30 and the second connector 40 are connected together via the connecting sleeve 50, the sealing gasket 10 is subjected to uniform force. The forces applied by the first connector 30 and the second connector 40 to the sealing gasket 10 act perpendicularly on the sealing gasket 10, causing the sealing functional layer 2 to deform uniformly. This allows the sealing functional layer 2 to fully fill the gap between the metal skeleton layer 1 and the sealing end face, ensuring good contact between the sealing gasket 10 and both the first end face 32 and the second end face 42. This guarantees a good sealing effect of the sealing gasket 10 on the gap between the first connector 30 and the second connector 40, ensuring reliable sealing performance.
