Description

Technical Field

[0001] This utility model relates to the field of gasket technology, and more specifically to a precision-ground aluminum alloy gasket. Background Technology

[0002] Gaskets are materials placed between two planes to enhance the seal. They are sealing elements placed between static sealing surfaces to prevent fluid leakage and are used to fill irregularities on machined surfaces. Precision gaskets are a type of gasket; they have precise dimensions and shapes and provide sealing, isolation, and support functions during equipment assembly and operation.

[0003] For example, the existing technology disclosure number CN218883000U describes a deformation-resistant precision gasket. This utility model allows the gasket to be completely removed from the metal sheet by tearing off the tear ring along the tangential direction of the gasket. This method does not cause axial deformation of the gasket edge, has uniform thickness, high installation accuracy, complete overall function, and strong practicality.

[0004] However, the existing technology described above still has the following problems in use: after long-term use, the upper and lower surfaces of the traditional precision aluminum alloy gaskets that connect the gasket to the equipment suffer severe wear, while the middle part of the gasket wears less. Since precision aluminum alloy gaskets are usually molded as a single piece, the entire gasket needs to be replaced, resulting in waste and increased usage costs. Based on this, this utility model provides a detachable and replaceable precision-ground aluminum alloy gasket. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a precision-ground aluminum alloy gasket, which consists of an upper layer, a middle layer, and a lower layer to form the main body of the precision gasket. The detachable design facilitates subsequent disassembly and replacement of individual layers, thereby saving usage costs. Furthermore, the first and second rubber sealing rings improve the sealing performance of the precision gasket main body during installation, while also absorbing and buffering vibrations at the connection points of the precision gasket main body, reducing vibration transmission, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision-ground aluminum alloy gasket, comprising a precision gasket body, wherein the precision gasket body comprises an upper layer, a middle layer and a lower layer stacked sequentially from top to bottom, wherein the top and bottom of the middle layer are machined with annular grooves, the upper layer and the lower layer are respectively disposed in the two annular grooves, wherein a first rubber sealing ring is provided between the middle layer and the upper and lower layers, wherein the top of the upper layer and the bottom of the lower layer are provided with two convex rings and multiple convex strips distributed in an annular array, wherein the multiple convex rings are respectively fixed to the upper layer and the lower layer, and a second rubber sealing ring is sleeved on the outer wall of each convex ring.

[0007] In a preferred embodiment, the top surface of the upper sheet and the bottom surface of the lower sheet are both machined with grooves equal in number to the number of protrusions. The protrusions are fixed inside the grooves and extend out of the grooves. The multiple protrusions make the surfaces of the upper and lower sheets uneven, thereby increasing the friction when they are connected to the equipment, and thus improving the connection firmness of the precision gasket body to a certain extent.

[0008] In a preferred embodiment, each protrusion has two arc-shaped grooves machined on its outer wall, and the second rubber sealing ring is disposed in the arc-shaped grooves, which can improve the stability of the second rubber sealing ring.

[0009] In a preferred embodiment, multiple reinforcing ribs are fixedly arranged in a ring array on the inner walls of the two annular grooves. The bottom of the upper layer and the top of the lower layer are machined with positioning grooves with the same number of reinforcing ribs. The end of the reinforcing rib near the positioning groove is inserted into the positioning groove. The reinforcing ribs can improve the strength of the entire precision gasket body and limit the upper and lower layers to prevent them from rotating and affecting the connection firmness.

[0010] In a preferred embodiment, the outer wall surface of the upper layer and the outer wall surface of the lower layer are both machined with a plurality of slots arranged in a ring array. The outer wall surface of the middle layer is provided with the same number of mounting slots as the number of slots. Each mounting slot is fixed with a spring pin, which is inserted into the slot to improve the connection between the upper layer, the lower layer and the middle layer, and facilitates the subsequent disassembly of the upper layer and the lower layer.

[0011] In a preferred embodiment, the upper, middle, and lower layers are all made of aluminum alloy, and the protrusions are made of thermally conductive metal material, which can further improve the thermal conductivity of the upper and lower layers.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model consists of an upper layer, a middle layer, and a lower layer forming a precision gasket body. The detachable design facilitates the replacement of individual layers, thereby saving usage costs. The first and second rubber sealing rings improve the sealing performance of the precision gasket body during installation, while also absorbing and buffering vibrations at the connection points of the precision gasket body, reducing vibration transmission.

[0014] 2. By adding multiple raised strips to the surfaces of the upper and lower sheets, the unevenness of the surfaces increases friction, thereby improving the firmness of the connection between the upper and lower sheets and the equipment to a certain extent. Furthermore, the raised strips are made of thermally conductive metal material, which can further improve the thermal conductivity of the upper and lower sheets. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figures 1-5 This utility model provides a precision-ground aluminum alloy gasket, including a precision gasket body 1. The precision gasket body 1 includes an upper layer 101, a middle layer 102, and a lower layer 103 stacked from top to bottom. The upper layer 101, the middle layer 102, and the lower layer 103 are all made of aluminum alloy. The top and bottom of the middle layer 102 are machined with annular grooves 104. The upper layer 101 and the lower layer 103 are respectively disposed in the two annular grooves 104. A first rubber sealing ring 2 is provided between the middle layer 102 and the upper layer 101 and the lower layer 103. The top of the upper layer 101 and the bottom of the lower layer 103 are provided with two protruding rings 3. Multiple protruding rings 3 are respectively fixed to the upper layer 101 and the lower layer 103. A second rubber sealing ring 5 is sleeved on the outer wall of each protruding ring 3.

[0024] Furthermore, multiple reinforcing ribs 8 are fixedly arranged in a ring array on the inner wall of both annular grooves 104. The bottom of the upper layer 101 and the top of the lower layer 103 are both machined with positioning grooves 9 in the same number as the reinforcing ribs 8. The end of the reinforcing rib 8 near the positioning groove 9 is inserted into the positioning groove 9.

[0025] The outer wall surface of the upper layer 101 and the outer wall surface of the lower layer 103 are both machined with a plurality of slots 10 arranged in a ring array. The outer wall surface of the middle layer 102 is provided with the same number of mounting grooves 11 as the slots 10. Each mounting groove 11 is fixedly provided with a spring pin 12, which is inserted into the slot 10. The connection between the spring pin 12 and the slot 10 is fixed, which can improve the connection between the upper layer 101 and the lower layer 103 and the middle layer 102 to a certain extent, and also facilitates the quick disassembly and replacement of the upper layer 101 and the lower layer 103.

[0026] In practical use, the upper layer 101, middle layer 102, and lower layer 103 form the precision gasket body 1. A first rubber sealing ring 2 is placed between the middle layer 102 and the upper and lower layers 101 and 103. Two layers of second rubber sealing rings 5 ​​are placed on the surfaces of the upper layer 101 and the lower layer 103. The second rubber sealing rings 5 ​​are supported and limited by the convex ring 3. The first rubber sealing rings 2 and the second rubber sealing rings 5 ​​can improve the sealing performance of the precision gasket body 1 during installation and can also absorb and buffer the connection of the precision gasket body 1. To reduce vibration transmission, the upper layer 101 and the lower layer 103 are respectively inserted into two annular grooves 104, and both are connected to the reinforcing rib 8 to prevent rotation. This improves the stability of the connection between the upper layer 101 and the lower layer 103 and the middle layer 102. The precision gasket body 1 adopts a detachable design, which does not affect the sealing performance and facilitates the subsequent disassembly and replacement of individual layers, thereby saving usage costs. In addition, removing the upper layer 101 and the lower layer 103 also facilitates the removal and replacement of the first rubber sealing ring 2.

[0027] Refer to the instruction manual appendix Figures 1-5 The top of the upper layer 101 and the bottom of the lower layer 103 are provided with a plurality of protrusions 4 arranged in a ring array. The protrusions 4 are made of thermally conductive metal material. The top surface of the upper layer 101 and the bottom surface of the lower layer 103 are both machined with the same number of grooves 6 as the protrusions 4. The protrusions 4 are fixed inside the grooves 6 and the surface of the protrusions 4 extends out of the grooves 6. The outer wall of each protrusion 4 is machined with two arc-shaped grooves 7. The second rubber sealing ring 5 is disposed in the arc-shaped grooves 7.

[0028] By providing raised strips 4 on both the surface of the upper layer 101 and the surface of the lower layer 103, and setting the thickness of the raised strips 4 to be less than the thickness of the second rubber sealing ring 5, when the precision gasket body 1 is connected to the equipment, the raised strips 4 make the surfaces of the upper layer 101 and the lower layer 103 uneven, increasing the friction between the two surfaces, thereby improving the connection firmness to a certain extent. Furthermore, the raised strips 4 are made of thermally conductive metal materials (such as copper), which can further improve the thermal conductivity of the upper layer 101 and the lower layer 103.

[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
