[0019] 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.
[0020] Please see Figure 1-5 This utility model provides a technical solution: a flange gasket for convenient positioning and installation, including a flange 1, a connecting pipe 2, a first flange gasket 3, a second flange gasket 4, a sealing ring mounting groove 5, a sealing ring 6, a threaded mounting groove 7, a positioning mounting ring 8, a positioning splicing buckle 9, and a positioning splicing buckle groove 10. The second flange gasket 4 is installed at one end of the first flange gasket 3, and the flange 1 is fitted to the outer walls of both the first flange gasket 3 and the second flange gasket 4. The first flange gasket 3 is positioned and spliced with the second flange gasket 4 through the positioning splicing buckle 9 and the positioning splicing buckle groove 10. The positioning splicing buckle 9 and the positioning splicing buckle groove 10 are distributed in a ring matrix on the first flange gasket 3 and the second flange gasket 4, which makes the splicing installation of the first flange gasket 3 and the second flange gasket 4 more stable and avoids installation misalignment.
[0021] The first flange gasket 3 and the second flange gasket 4 are distributed in a double layer on the flange 1, and the first flange gasket 3 and the second flange gasket 4 are installed with the flange 1 by compression sealing through the sealing ring 6. This provides double-layer support for the first flange gasket 3 and the second flange gasket 4, and the sealing effect can be achieved by the sealing ring 6. The first flange gasket 3 and the second flange gasket 4 are installed with the flange 1 by positioning and insertion splicing through the positioning and installation ring 8. This makes it easy for the first flange gasket 3 and the second flange gasket 4 to be positioned and inserted into the flange 1, and the installation is precise and stable.
[0022] One end of the flange 1 is connected to a connecting pipe 2. The other edge of the first flange gasket 3 and the second flange gasket 4 is provided with a sealing ring mounting groove 5, and a sealing ring 6 is inserted into the inner wall of the sealing ring mounting groove 5. The sealing ring 6 is installed in a snap-fit connection with the first flange gasket 3 and the second flange gasket 4 through the sealing ring mounting groove 5. The sealing ring 6 and the sealing ring mounting groove 5 are distributed in three concentric layers at one end of the first flange gasket 3 and the second flange gasket 4. This makes it easy to snap-fit the sealing ring 6, easy to replace, and can provide a three-layer seal.
[0023] The first flange gasket 3 has a positioning splicing groove 10 on one edge, and a positioning splicing block 9 is inserted into the inner wall of the positioning splicing groove 10. The positioning splicing block 9 is fixedly connected to one edge of the second flange gasket 4. The inner walls of the first flange gasket 3 and the second flange gasket 4 have threaded mounting grooves 7, and a positioning mounting ring 8 is inserted into the inner wall of the threaded mounting groove 7. One edge of the inner wall of the positioning mounting ring 8 is inclined, and the positioning mounting ring 8 is rotatably spliced with the first flange gasket 3 and the second flange gasket 4 through the threaded mounting groove 7. This makes the positioning mounting ring 8 easy and quick to disassemble and install, and can be replaced independently. The positioning mounting ring 8 is inserted into the inner wall of the flange 1.
[0024] Working principle: When using this conveniently positioned flange gasket, firstly, the flange 1 and connecting pipe 2 of the device are rotated and spliced together. Then, the first flange gasket 3 and the second flange gasket 4 are inserted into the flange 1 through the positioning and installation ring 8 for positioning and splicing. Next, the two sets of flanges 1 are connected, and the first flange gasket 3 and the second flange gasket 4 are positioned and spliced through the positioning and splicing buckle 9 and the positioning and splicing groove 10. Then, bolts are used to fix them, thereby squeezing and locking the first flange gasket 3 and the second flange gasket 4. After installation, the sealing ring 6 can be used to achieve a three-layer compression seal with the flange 1. When the sealing ring 6 and the positioning and installation ring 8 need to be replaced, they can be quickly replaced by inserting and rotating them through the sealing ring installation groove 5 and the threaded installation groove 7. This is the usage process of this conveniently positioned flange gasket.
