Description

Technical Field

[0001] This utility model relates to the field of flange structure technology, specifically a composite isolation gasket structure. Background Technology

[0002] In the field of fluid transportation, when it comes to transporting corrosive gases, liquids and other types of fluids, the diversity and complexity of the working environment, as well as the significant differences in the materials used in the equipment manufacturing process, and the connection between different types of non-metallic materials, different types of metallic materials, and metal and non-metallic materials, put forward higher requirements for the sealing performance, corrosion resistance and service life of the connection.

[0003] Upon investigation, a utility model patent discloses a composite isolation gasket structure (publication number: CN209761977U), which includes a gasket. The main structure of the gasket is a connecting ring. One end face of the connecting ring is provided with multiple sleeves perpendicular to the end face. The gasket consists of a base layer and an anti-corrosion layer covering the surface of the base layer.

[0004] In the aforementioned patent, the anti-corrosion layer covering the surface of the base layer can effectively prevent adhesion (non-metallic flanges) and electrochemical corrosion (metallic flanges) caused by direct contact between fasteners and flanges, thereby improving the service life of fasteners, flanges, pipes, etc. However, when the gap space between the parts to be assembled is small, the operating channel is limited, or when a gasket needs to be added to a partially assembled device, the integral gasket cannot be disassembled and is usually difficult to be successfully embedded in the target position, which may reduce the installation efficiency.

[0005] Therefore, this utility model provides a composite isolation pad structure to solve the above problems. Utility Model Content

[0026] 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.

[0027] This utility model provides a composite isolation pad structure, such as Figure 1 , Figure 2 , Figure 4 , Figure 4 , Figure 5 and Figure 6 As shown, the isolation gasket structure includes a semi-circular gasket body 1, connecting plates 2 fixedly installed on both sides of the semi-circular gasket body 1, a fixing groove 3 opened inside one of the connecting plates 2, an insert plate 4 fixedly installed on one side of the other connecting plate 2, and a loading and unloading mechanism provided inside the fixing groove 3 for installing or removing the two semi-circular gasket bodies 1.

[0028] The loading and unloading mechanism includes telescopic rods 5 fixedly installed on the inner walls of both sides of the fixed groove 3, a first insert 7 and a second insert 8 fixedly installed on the movable ends of the two telescopic rods 5 on the same inner wall, a first spring 6 sleeved on the side surface of the telescopic rods 5, an inclined block 9 fixedly installed on the first insert 7 and the second insert 8, a control frame 10 slidably installed inside the fixed groove 3, a slide rod 11 fixedly installed on one side of the control frame 10, and a pressing plate 12 fixedly installed on the end of the slide rod 11 away from the control frame 10. The two sides of the insert plate 4 are respectively provided with slots for the first insert 7 and the second insert 8 to be inserted.

[0029] One end of the first spring 6 is fixedly connected to the inner wall of one side of the fixing groove 3, and the other end of the first spring 6 is fixedly connected to one side of the first insert 7 or the second insert 8.

[0030] The inclined surface of the control frame 10 fits into the inclined surface of the inclined block 9, and the slide rod 11 passes through the fixing groove 3.

[0031] In use, the isolation gasket structure first connects two semi-circular gasket bodies 1 via connecting plate 2. Then, insert plate 4 is inserted into the fixing slot 3. During insertion, insert plate 4 compresses the first insert 7 and the second insert 8, causing them to retract via telescopic rod 5. Simultaneously, the first spring 6 is compressed. The first insert 7 and the second insert 8 are of different sizes, as are the two slots, to prevent the second insert 8 from being inserted into the slot before insert plate 4 is fully inserted. Once insert plate 4 is fully inserted into the fixing slot 3, the first spring 6 uses its elasticity to push the first insert 7 and the second insert 8... The second insert 8 is reset and moved, so that the first insert 7 and the second insert 8 are respectively inserted into the inside of the slot, thereby fixing the insert plate 4 and splicing and fixing the two semi-circular gasket bodies 1. When disassembly is required, by pressing the pressing plate 12, the pressing plate 12 will drive the control frame 10 to move through the slide rod 11, so that the inclined surface of the control frame 10 will press against the inclined surface of the inclined block 9, thereby pushing the first insert 7 and the second insert 8 to retract and move. When the first insert 7 and the second insert 8 are completely pulled out from the inside of the slot, the insert plate 4 can be pulled out from the inside of the fixing groove 3, thereby separating the two semi-circular gasket bodies 1. The operation is simple and convenient, and easy for the staff to use.

[0032] In order to reposition the parts after disassembly, such as Figure 1 , Figure 4 and Figure 6 As shown, a movable plate 13 is slidably connected inside the fixed groove 3. The side of the control frame 10 away from the slide rod 11 is in contact with the side of the movable plate 13. A limit slider 14 is provided inside the fixed groove 3.

[0033] The inner walls on both sides of the fixed groove 3 are provided with limiting grooves 15 for the sliding of the limiting slider 14. A second spring 16 is provided inside the fixed groove 3. One end of the second spring 16 is fixedly connected to one side of the inner wall of the fixed groove 3, and the other end of the second spring 16 is fixedly connected to the side of the moving plate 13 away from the control frame 10.

[0034] When the pressure plate 12 is pushed inward, the control frame 10 moves synchronously. The movement of the control frame 10 pushes the moving plate 13 and the limiting slider 14 along the limiting groove 15, while simultaneously squeezing the second spring 16. When the pressure plate 12 is not subjected to external force, the second spring 16 will use its own elasticity to push the moving plate 13 to reset. During the reset movement, the moving plate 13 will drive the control frame 10 to reset. During the reset movement, the control frame 10 will move away from the inclined block 9. At this time, the first spring 6 will again use its own elasticity to push the first insert 7 and the second insert 8 to reset, ensuring that each part can be reset after disassembly, which is convenient for the next use and improves the practicality of the pressure plate structure.

[0035] Furthermore, to reduce the shaking that occurs after the two semi-circular gasket bodies 1 are assembled, such as... Figure 1 , Figure 2 and Figure 5 As shown, a protrusion 17 is fixedly connected to one side of the connecting plate 2, and a groove 18 that matches the protrusion 17 is provided on one side of the connecting plate 2.

[0036] When in use, the two semi-circular gasket bodies 1 are spliced ​​together, so that the protrusion 17 is inserted into the groove 18. Through the cooperation of the protrusion 17 and the groove 18, the two semi-circular gasket bodies 1 can be limited, reducing the shaking that occurs after the two semi-circular gasket bodies 1 are spliced, and further improving the stability of the isolation gasket structure. At the same time, the setting of the protrusion 17 and the groove 18 also makes it easier for workers to splice and disassemble the two semi-circular gasket bodies 1, improving work efficiency.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
