Description

Technical Field

[0001] This utility model belongs to the field of sealing gasket technology, specifically relating to a pressure-bearing sealing gasket with ultra-strong wear resistance. Background Technology

[0002] In various industrial equipment, piping systems, and mechanical devices, gaskets are key sealing elements. Rubber gaskets come in various styles, most of which are made of rubber. Commonly seen are transparent gaskets, EVA gaskets, etc. They have excellent wear resistance, high elasticity, tensile strength, and elongation. However, rubber gaskets are prone to aging in air, become sticky when heated, and easily swell and dissolve in mineral oil or gasoline. They are alkali-resistant but not resistant to strong acids.

[0003] For example, a wear-resistant rubber gasket is described in application number CN202020877763.5. This device strengthens the rubber gasket structure to make it more compact, improves the strength of the rubber gasket structure, makes it less prone to breakage, ensures the integrity of the rubber gasket, and improves the service life of the gasket.

[0004] In the above cases, due to the different objects that the top and bottom of the sealing gasket contact, the degree of damage is also different. When the top, bottom, or one side of the rubber gasket is worn, the entire rubber sealing gasket needs to be replaced. However, the other unworn side of the sealing gasket can be used. Replacing the entire rubber gasket is a waste. Therefore, this utility model provides a pressure sealing gasket with super wear resistance. Utility Model Content

[0005] The purpose of this invention is to provide a pressure-bearing sealing gasket with superior wear resistance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressure-bearing sealing gasket with ultra-strong wear resistance, comprising a main gasket, an upper gasket on the top of the main gasket, a lower gasket at the bottom of the main gasket, the main gasket, the upper gasket, and the lower gasket all being annular structures, the main gasket having two symmetrically arranged second mating grooves on the side facing the upper gasket, and the main gasket having a first mating groove on the side facing the lower gasket.

[0007] In a preferred embodiment, the bottom of the upper pad is provided with two arc-shaped snap-fit ​​portions, the shape of which is the same as that of the second mating groove.

[0008] In a preferred embodiment, the top of the lower pad is provided with a docking portion, the top of the docking portion is circular, and the shape of the docking portion is adapted to the first docking groove, and two second docking grooves are wrapped around the outside of the first docking groove.

[0009] In a preferred embodiment, the outer and inner rings at the top and bottom of the main body pad are provided with fitting grooves, and a limiting groove is provided on the outward-facing side of the fitting groove.

[0010] In a preferred embodiment, the outer and inner rings of the bottom of the upper pad and the outer and inner rings of the top of the lower pad are provided with fitting portions adapted to the fitting groove, and each fitting portion has a limiting protrusion on the side facing the fitting groove.

[0011] In a preferred embodiment, each of the fitting portions has an outward-facing groove at its top, and each fitting groove has an extension at its top that is adapted to the groove.

[0012] In a preferred embodiment, the main pad, the upper pad, and the lower pad are all integrally injection molded structures.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This high-wear-resistant pressure sealing gasket consists of a main gasket, an upper gasket, and a lower gasket. The layers are detachably connected by a specific mating structure. This design allows for the replacement of individual layers (such as the upper or lower gasket) when they wear out, without replacing the entire gasket. This significantly improves the gasket's efficiency and economy. Since each layer of the gasket can be replaced independently, when one layer wears out, the other unworn layers can still be used, reducing material waste. This has significant economic benefits for gaskets that require long-term use and are prone to wear.

[0015] This high-wear-resistant pressure sealing gasket allows for the selection of different wear-resistant materials or special wear-resistant treatments for each layer according to actual needs, thereby further improving the overall wear resistance of the gasket. In addition, when a layer wears out, it can be replaced with a new material layer with higher wear resistance to adapt to different working environments and requirements. Attached Figure Description

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3 This utility model provides a pressure sealing gasket with super wear resistance, including a main gasket 1, an upper gasket 2 on the top of the main gasket 1, and a lower gasket 3 at the bottom of the main gasket 1. The main gasket 1, the upper gasket 2, and the lower gasket 3 are all annular structures. The main gasket 1 has two symmetrically arranged second mating grooves 102 on the side facing the upper gasket 2, and a first mating groove 101 on the side facing the lower gasket 3. The bottom of the upper gasket 2 has two arc-shaped snap-fit ​​parts 201, the shape of which is the same as that of the second mating grooves 102. The top of the lower gasket 3 has a mating part 304, the top of which is circular and its shape is adapted to the first mating groove 101. The two second mating grooves 102 wrap around the outside of the first mating groove 101.

[0023] When assembling this high-wear-resistant pressure-bearing sealing gasket, the lower gasket 3 is first joined to the main gasket 1. The mating part 304 at the top of the lower gasket 3 is aligned with the first mating groove 101 inside the side of the main gasket 1 facing the lower gasket 3. Since the top of the mating part 304 is round and its shape matches the first mating groove 101, by applying appropriate pressure, the mating part 304 is smoothly inserted into the first mating groove 101, thus connecting the lower gasket 3 and the main gasket 1. Next, the upper gasket 2 is assembled with the main gasket 1. The two arc-shaped snap-fit ​​parts 201 at the bottom of the upper gasket 2 are aligned with the two symmetrically arranged second mating grooves 102 inside the side of the main gasket 1 facing the upper gasket 2. Because the shape of the snap-fit ​​part 201 is the same as that of the second mating groove 102, appropriate pressure is applied again to make the snap-fit ​​part 201 embed into the second mating groove 102, thus completing the connection between the upper gasket 2 and the main gasket 1. Due to the compression of the mating part 304, the second mating groove 102 and the snap-fit ​​part 201 are more tightly connected, which improves the stability of the gasket connection. The assembled gasket is installed in the corresponding industrial equipment, pipeline system or mechanical device to seal the gap between the two components. During the operation of the equipment, the gasket bears a certain pressure. The main gasket 1, the upper gasket 2 and the lower gasket 3 work together to prevent media leakage by tightly fitting the contact surface.

[0024] After a period of use, if wear is found on the upper pad 2 or the lower pad 3, it needs to be replaced. Since the upper pad 2 is detachably connected to the main pad 1 via a snap-fit ​​part 201 and a second mating groove 102, simply apply appropriate external force to overcome the friction between the snap-fit ​​part 201 and the second mating groove 102 to remove the upper pad 2 from the main pad 1. Then, follow the assembly process described above to insert the snap-fit ​​part 201 into the second mating groove 102 of the main pad 1 to complete the replacement of the upper pad 2. The replacement process for the lower pad 3 is similar to that of the upper pad 2. Simply disassemble the connection between the mating part 304 and the first mating groove 101, and then install the new lower pad 3.

[0025] The specific docking structure of the snap-fit ​​part 201 with the second docking groove 102 and the docking part 304 with the first docking groove 101 makes the assembly and disassembly of the gasket simple and quick. In practical applications, it can greatly shorten the installation and maintenance time of the equipment and improve work efficiency. For example, in some industrial scenarios where gaskets need to be replaced frequently, this convenient assembly and disassembly method can significantly reduce downtime and reduce production losses. The matching design of the docking part 304 with the first docking groove 101 and the snap-fit ​​part 201 with the second docking groove 102 ensures that each layer can be accurately positioned. When the gasket is under pressure, this accurate positioning allows each layer to fit tightly without misalignment or loosening, thereby ensuring the sealing performance and pressure resistance of the gasket.

[0026] In practical use, the objects that the top and bottom of the sealing gasket come into contact with are different, and the degree of wear may also be different. This layered design allows for targeted replacement of severely worn layers based on the actual wear condition. For example, if the upper gasket 2 comes into contact with a rougher object and wears faster, while the lower gasket 3 wears slower, then only the upper gasket 2 needs to be replaced, without replacing the entire sealing gasket, thus improving the flexibility and economy of using the sealing gasket.

[0027] In this embodiment, the outer and inner rings at the top and bottom of the main body pad 1 are provided with fitting grooves 103. The outer side of the fitting groove 103 is provided with a limiting groove 105. The outer and inner rings at the bottom of the upper pad 2 and the outer and inner rings at the top of the lower pad 3 are provided with fitting parts 301 that are adapted to the fitting grooves 103. Each fitting part 301 is provided with a limiting protrusion 302 on the side facing the fitting groove 103. The outer side of the top of each fitting part 301 is provided with a slanted groove 303. The top of each fitting groove 103 is provided with an extension part 104 that is adapted to the slanted groove 303.

[0028] When assembling the upper pad 2 and the lower pad 3 with the main pad 1, the fitting portions 301 at the bottom outer and inner rings of the upper pad 2, and the fitting portions 301 at the top outer and inner rings of the lower pad 3, will align with the corresponding fitting grooves 103 at the top and bottom of the main pad 1. As pressure is applied, the fitting portions 301 gradually embed into the fitting grooves 103. This fitting design allows the docking process to proceed smoothly, ensuring that the layers initially achieve positional correspondence. After the fitting portions 301 are embedded into the fitting grooves 103, the limiting protrusions 302 on the fitting portions 301 will engage with the limiting grooves 105 on the outward-facing side of the fitting grooves 103. The 05 mechanism restricts the relative horizontal movement between layers, further enhancing the stability of the connection between layers and preventing misalignment or sliding between layers when the sealing gasket is under pressure or subjected to external force. At the same time, the inclined groove 303 on the top of the bonding part 301 facing outwards will cooperate with the extension 104 on the top of the bonding groove 103. During the assembly process, the contact surface between the inclined groove 303 and the extension 104 can play a certain guiding role, guiding the bonding part 301 to be more accurately embedded in the bonding groove 103. Moreover, this cooperation can also increase the contact area between layers, improve the sealing effect, and prevent the medium from leaking from the gaps between layers.

[0029] The tight fit between the mating part 301 and the mating groove 103, as well as the adaptive design of the inclined groove 303 and the extension part 104, greatly increases the contact area between the layers and reduces the channels for media leakage. Under harsh working conditions such as high pressure, high temperature or corrosive media, it can effectively prevent the media from leaking from the gaps between the layers of the sealing gasket, improve the reliability and stability of the seal, and ensure the safe operation of the equipment. The cooperation between the limiting protrusion 302 and the limiting groove 105 restricts the relative horizontal movement between the layers, so that the main gasket 1, the upper gasket 2 and the lower gasket 3 can act as a stable whole to withstand pressure and external forces. During the operation of the equipment, it avoids the seal failure or gasket damage caused by misalignment or sliding of the layers, and extends the service life of the sealing gasket.

[0030] In this embodiment, the main gasket 1, the upper gasket 2, and the lower gasket 3 are all integral injection molded structures. Integral injection molding can complete the molding of each layer of the sealing gasket in one go, reducing production processes and assembly steps, and greatly shortening the production cycle.

[0031] The working principle and usage process of this utility model are as follows: First, the lower pad 3 is joined with the main pad 1. The joining part 304 at the top of the lower pad 3 is aligned with the first joining groove 101 inside the side of the main pad 1 facing the lower pad 3. Since the top of the joining part 304 is round and its shape matches the first joining groove 101, by applying appropriate pressure, the joining part 304 is smoothly inserted into the first joining groove 101, thus connecting the lower pad 3 and the main pad 1. Next, the upper pad 2 is assembled with the main pad 1. The two arc-shaped snap-fit ​​parts 201 at the bottom of the upper pad 2 are aligned with the two symmetrically arranged second joining grooves 102 inside the side of the main pad 1 facing the upper pad 2. Since the shape of the snap-fit ​​parts 201 is the same as the second joining grooves 102, appropriate pressure is applied again to make the snap-fit ​​parts 201 insert into the second joining grooves 102, thus completing the connection between the upper pad 2 and the main pad 1. Due to the compression of the joining part 304, the second joining grooves 102 and the snap-fit ​​parts are aligned. The joint 201 is tighter, improving the stability of the gasket connection. The assembled gasket is installed in the corresponding industrial equipment, pipeline system or mechanical device to seal the gap between two components. During equipment operation, the gasket bears a certain pressure. The main gasket 1, upper gasket 2 and lower gasket 3 work together to prevent media leakage by tightly fitting the contact surface. After a period of use, if wear is found on the upper gasket 2 or lower gasket 3, it needs to be replaced. Since the upper gasket 2 and the main gasket 1 are detachably connected by the snap-fit ​​part 201 and the second mating groove 102, only appropriate external force needs to be applied to overcome the friction between the snap-fit ​​part 201 and the second mating groove 102 to remove the upper gasket 2 from the main gasket 1. Then, the new upper gasket 2 is assembled by inserting its snap-fit ​​part 201 into the second mating groove 102 of the main gasket 1 to complete the replacement of the upper gasket 2.The replacement process for the lower pad 3 is similar to that of the upper pad 2. It involves disassembling the connection between the mating part 304 and the first mating groove 101, and then installing the new lower pad 3. When assembling the upper pad 2 and the lower pad 3 with the main body pad 1, the fitting parts 301 at the bottom outer and inner rings of the upper pad 2, and the fitting parts 301 at the top outer and inner rings of the lower pad 3, will align with the corresponding fitting grooves 103 at the top and bottom of the main body pad 1, respectively. As pressure is applied, the fitting parts 301 gradually embed into the fitting grooves 103. This adaptive design allows the mating process to proceed smoothly, ensuring that the layers initially achieve positional correspondence. After the fitting parts 301 are embedded into the fitting grooves 103, the limiting protrusions 302 on the fitting parts 301 will engage with the fitting grooves 103. In the limiting groove 105 on the outer side, the limiting protrusion 302 and the limiting groove 105 cooperate to restrict the relative horizontal movement between the layers, further enhancing the stability of the connection between the layers and preventing misalignment or sliding between the layers when the sealing gasket is under pressure or subjected to external force. At the same time, the inclined groove 303 provided on the outer side of the top of the fitting part 301 will cooperate with the extension 104 at the top of the fitting groove 103. During the assembly process, the contact surface between the inclined groove 303 and the extension 104 can play a certain guiding role, guiding the fitting part 301 to be more accurately embedded in the fitting groove 103. Moreover, this cooperation can also increase the contact area between the layers, improve the sealing effect, and prevent the medium from leaking from the gaps between the layers.
