Description

Technical Field

[0001] The invention relates to the technical field of mechanical connection, in particular to a flange gasket and a flange assembly. Background Art

[0002] Flange is a part that connects pipes to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection that is connected by flange, gasket and bolts as a combined sealing structure. There are holes on the flange, and bolts make the two flanges tightly connected.

[0003] The existing flange and its gasket need the cooperation of multiple workers during the installation process. If you are not careful, the gasket cannot be installed well, resulting in the gasket and the flange boss offset. Therefore, we propose a flange gasket and a flange assembly. Summary of the invention

Through the action of the plurality of return springs, the block inserted into the interior of the first flange is moved, and then the two adjacent blocks are moved away from each other, thereby realizing the preliminary connection between the first flange and the second flange, and making it more convenient to fix the first flange and the second flange by fixing bolts.

[0008] Preferably, a T-shaped slider is fixedly installed on the top of several of the blocks, and the T-shaped slider is inserted into the interior of the auxiliary block and slidably connected thereto. By setting the T-shaped slider on the top of the block, pressure is applied to the T-shaped slider to bring two adjacent blocks closer to each other, thereby moving the auxiliary block out from the interior of the first flange.

[0010] Preferably, the gasket is provided with holes and grooves that cooperate with a number of fixing bolts, and friction textures are provided on the corresponding two sides of the gasket. The two auxiliary blocks pass through the gasket and are slidably connected thereto.

[0023] The auxiliary structure includes two clamping blocks 7, both of which are slidably connected to the auxiliary block 6, and T-shaped slide bars 8 are fixedly installed on the corresponding two sides of the auxiliary block 6. The T-shaped slide bars 8 are inserted into the interior of the clamping blocks 7 and slidably connected thereto, and the two clamping blocks 7 are slidably connected to the first flange 1. A plurality of return springs 9 are fixedly installed on one side of the two clamping blocks 7 close to the auxiliary block 6 and on the corresponding two sides of the T-shaped slide bar 8, and one end of the plurality of return springs 9 away from the clamping blocks 7 is fixedly connected to the auxiliary block 6. Through the action of the plurality of return springs 9, the clamping block 7 inserted into the interior of the first flange 1 is moved, and then the two adjacent clamping blocks 7 are moved away from each other, so as to realize the preliminary connection between the first flange 1 and the second flange 2, so as to facilitate the fixing of the first flange 1 and the second flange 2 by the fixing bolts 11. At the same time, by connecting the first flange 1 and the second flange 2, it is realized that there is no need for multiple workers to cooperate in the installation.

[0024] A T-shaped slider 10 is fixedly installed on the top of several clamping blocks 7. The T-shaped slider 10 is inserted into the interior of the auxiliary block 6 and is slidably connected thereto. By setting the T-shaped slider 10 on the top of the clamping block 7, pressure is applied to the T-shaped slider 10 to bring two adjacent clamping blocks 7 closer to each other, thereby moving the auxiliary block 6 out from the inside of the first flange 1, thereby releasing the initial fixation of the first flange 1 and the second flange 2.

[0025] A first protective shell 12 and a second protective shell 13 are arranged on the outside of the first flange 1 and the second flange 2. Two slide grooves 15 are provided on the first protective shell 12. U-shaped plugs 16 are slidably connected inside the two slide grooves 15. Fixed blocks 14 are fixedly installed on the outside of the second protective shell 13 and on the corresponding two sides of the pipeline 5. The U-shaped plugs 16 are inserted into the inside of the fixed blocks 14 and slidably connected thereto. Threaded rods 17 are arranged on the tops of the two fixed blocks 14. The threaded rods 17 penetrate the U-shaped plugs 16 and are threadedly connected thereto. The threaded rods 17 are inserted into the inside of the fixed blocks 14 and are threadedly connected thereto. The first protective shell 12 and the second protective shell 13 are fixed with a plurality of bolts. 11 is a sliding connection, by inserting the U-shaped plug 16 into the inside of the slide groove 15 and the fixed block 14, and further fixing the fixed block 14 and the U-shaped plug 16 through the provided threaded rod 17, thereby achieving a fixed connection between the first protective shell 12 and the second protective shell 13, and the first protective shell 12 and the second protective shell 13 are provided to protect the first flange 1 and the second flange 2 inside, thereby further improving the service life of the first flange 1 and the second flange 2, and further by providing the first protective shell 12 and the second protective shell 13 and the fixing bolt 11 with a sliding connection, the position of the fixing bolt 11 is restricted, and the possibility of loosening of the fixing bolt 11 is reduced.

[0026] The gasket 4 is provided with holes and grooves that cooperate with a number of fixing bolts 11, and friction textures are provided on the corresponding two sides of the gasket 4. The two auxiliary blocks 6 pass through the gasket 4 and are slidably connected thereto. The friction textures provided on both sides of the gasket 4 increase the friction between the first flange 1 and the second flange 2, and further make the first flange 1 and the second flange 2 more stable when fixed. At the same time, the gasket 4 is provided with holes and through grooves that cooperate with the auxiliary blocks 6 and the fixing bolts 11, so as to facilitate the installation of the gasket 4.

[0027] Two sealing gaskets 18 are provided on one side where the first protective shell 12 and the second protective shell 13 are close to each other and on the corresponding two sides of the pipeline 5. Several sealing gaskets 18 are fixedly connected to the first flange 1 and the second flange 2. The outer surfaces and inner walls of the first protective shell 12 and the second protective shell 13 are coated with waterproof coating. By providing the sealing gasket 18 on the side where the first protective shell 12 and the second protective shell 13 are close to each other, the sealing effect of the first protective shell 12 and the second protective shell 13 is improved. At the same time, by providing the waterproof coating on the first protective shell 12 and the second protective shell 13, the possibility of the first protective shell 12 and the second protective shell 13 being damaged by moisture after a long time is prevented.

[0028] In summary, when the flange gasket and flange assembly are used, two insertion rods 3 are arranged on the top of the first flange 1, so that the insertion rods 3 penetrate the gasket 4 to limit its position, and the first flange 1 and the gasket 4 are coaxially positioned. Then, when a plurality of fixing bolts 11 are penetrated through the first flange 1 and the second flange 2 to fix them, the fixing bolts 11 penetrate the gasket 4 at the same time to facilitate the positioning and fixing of the gasket 4, making it more convenient to install.

[0029] The position of the gasket 4 is preliminarily positioned by the provided insertion rod 3, and the first flange 1 is abutted against the second flange 2, so that the plurality of insertion rods 3 are inserted into the interior of the second flange 2, further driving the auxiliary block 6 to be inserted into the interior of the first flange 1, and the plurality of reset springs 9 are used to move the block 7 inserted into the interior of the first flange 1, so that the two adjacent blocks 7 are moved away from each other, thereby achieving a preliminary connection between the first flange 1 and the second flange 2, thereby facilitating more convenience in fixing the first flange 1 and the second flange 2 by the fixing bolts 11, and at the same time, by connecting the first flange 1 and the second flange 2, it is possible to achieve fixed installation of the first flange 1, the second flange 2 and the gasket 4 without the need for collaborative operation of multiple workers during installation, thereby improving the practicality of the device.

[0030] By setting a T-shaped slider 10 on the top of the block 7, the two adjacent blocks 7 are brought closer to each other by applying pressure to the T-shaped slider 10, so that the auxiliary block 6 is moved out from the inside of the first flange 1, and the initial fixation of the first flange 1 and the second flange 2 is released. At the same time, the friction lines are set on both sides of the gasket 4 to increase the friction between the first flange 1 and the second flange 2, and further make the first flange 1 and the second flange 2 more stable when fixed. In addition, a through groove that cooperates with the auxiliary block 6 is opened on the gasket 4, so that the auxiliary block 6 can pass through the gasket 4 and be inserted into the inside of the first flange 1, so as to perform a preliminary connection between the first flange 1, the second flange 2 and the gasket 4.

[0031] By inserting the U-shaped plug 16 into the inside of the slide groove 15 and the fixed block 14 on the first protective shell 12 and the second protective shell 13 outside the first flange 1 and the second flange 2, and further fixing the fixed block 14 with the U-shaped plug 16 through the provided threaded rod 17, the fixed connection of the first protective shell 12 and the second protective shell 13 is achieved, and the first protective shell 12 and the second protective shell 13 are provided to protect the first flange 1 and the second flange 2 inside, thereby further improving the service life of the first flange 1 and the second flange 2, and by providing a sealing gasket 18 on the side where the first protective shell 12 and the second protective shell 13 are close to each other, the sealing effect of the first protective shell 12 and the second protective shell 13 is improved, and by the first protective shell 12 and the second protective shell 13 being provided and slidingly connected with the fixing bolt 11, the position of the fixing bolt 11 is restricted, thereby further reducing the possibility of loosening of the fixing bolt 11.
