Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a high-strength flange for hydraulic equipment. Background Art

[0002] Flange, also known as flange flange or flange, is a part that connects shafts to each other and is used for connecting pipe ends. It is also used as flange on equipment inlet and outlet for connecting two devices. The flange used in general hydraulic equipment is called hydraulic flange, and hydraulic flange is generally strong and can withstand greater pressure.

[0003] However, the existing hydraulic equipment uses a high-strength flange. During use, the existing sealing ring gaskets are mostly directly bonded to the flange to prevent them from falling off, which makes it inconvenient to disassemble the sealing ring gasket when replacing it later.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] The embodiment of the utility model provides a high-strength flange for hydraulic equipment, which is intended to solve the technical problem that it is inconvenient to replace and disassemble the sealing ring gasket in the prior art;

[0028] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0029] A high-strength flange for hydraulic equipment includes a first flange 1, an inner ring 101 is provided inside the first flange 1, four groups of limiting grooves 1011 are provided on the inner wall of the inner ring 101, the limiting grooves 1011 limit and fix the sealing gasket 3, four groups of fixing grooves 1012 are provided on the top of the inner ring 101, the fixing grooves 1012 limit and fix the fixing ears 302, plug holes 1013 are provided inside the fixing grooves 1012, eight groups of docking columns 102 are fixedly connected to the outer side of the inner ring 101 and located on the top of the first flange 1, and threaded mounting holes 1021 are provided inside the docking columns 102.

[0030] Among them, see Figure 4 and Figure 5The top bolts of the first flange 1 are connected to the second flange 2, and an inner ring 201 is provided inside the second flange 2 at a position corresponding to the inner ring 101. The internal structure of the inner ring 201 is the same as the internal structure of the inner ring 101, and the inner ring 201 limits and fixes the sealing gasket 3. A fixing groove 2011 is provided at a position of the inner ring 201 corresponding to the fixing groove 1012, and the fixing groove 2011 limits and fixes the fixing ear 302. A plug-in rod 2012 is fixedly connected inside the fixing groove 2011 at a position corresponding to the plug-in hole 1013, and the plug-in rod 2012 is plug-connected to the plug-in hole 1013, which is convenient for quick docking and installation and fixation between the first flange 1 and the second flange 2.

[0031] For further information, see Figure 1 , Figure 4 and Figure 5 The bottom of the second flange 2 and the position corresponding to the docking column 1 102 are fixedly connected with a docking column 202. The docking column 1 102 and the docking column 202 can reduce the contact area between the hexagonal bolt 4 and the air, and prevent the hexagonal bolt 4 from rusting and oxidizing, which is inconvenient for later disassembly. The internal structure of the docking column 202 is the same as the internal structure of the docking column 102. The docking column 102 and the docking column 202 are connected by the hexagonal bolt 4. The hexagonal bolt 4 can withstand higher stress and torque. Compared with other types of screws, the hexagonal bolt 4 has higher strength and load capacity, can maintain stability under greater force, and enhance the connection strength between the first flange 1 and the second flange 2.

[0032] For further information, see Figure 2 , Figure 4 and Figure 6 The inner ring 1 101 and the inner ring 2 201 are both plugged with sealing gaskets 3, and the outer side of the sealing gasket 3 and the position corresponding to the limiting groove 1011 are fixedly connected with a limiting strip 301, and the sealing gasket 3 is plugged and connected with the limiting groove 1011 to be limited and fixed to prevent the sealing gasket 3 from moving inside the inner ring 1 101 and the inner ring 2 201. A fixing ear 302 is fixedly connected to one side of the sealing gasket 3 and the position corresponding to the fixing groove 1 1012. The fixing ear 302 is fixedly connected to the fixing groove 1 1012. 2 are respectively embedded in the fixing groove 1 1012 and the fixing groove 2 2011 for limiting fixation, so as to improve the fixing stability of the sealing gasket 3 and prevent the sealing gasket 3 from loosening and falling off during the installation process of the flange. A through hole 3021 is provided inside the fixing ear 302 at a position corresponding to the plug-in hole 1013. The second flange 2 is plugged and connected with the plug-in hole 1013 at the top of the first flange 1 through the through hole 3021 by the plug-in rod 2012, so as to further improve the fixing stability of the sealing gasket 3.

[0033] The working process of the utility model is as follows: first, the sealing gasket 3 is plugged into the inner ring 101 and the inner ring 201 by means of the limit strip 301 and the limit groove 1011, and the fixing ears 302 are respectively embedded in the fixing groove 1012 and the fixing groove 2011 for limit fixing, so as to improve the fixing stability of the sealing gasket 3 and prevent the sealing gasket 3 from loosening and falling during the installation process of the flange. After the first flange 1 is installed on the hydraulic equipment, the second flange 2 is plugged into the plug hole 1013 at the top of the first flange 1 through the through hole 3021 by means of the plug rod 2012, and the plug hole 1013 at the top of the first flange 1 is connected with the plug rod 2012. The first flange 1 is quickly docked for installation and fixation, which further improves the fixing stability of the sealing gasket 3 inside the flange. The docking column 1 102 and the docking column 2 202 are connected by hexagonal bolts 4. The hexagonal bolts 4 have higher strength and load capacity, and can maintain stability under greater force, thereby enhancing the connection strength between the first flange 1 and the second flange 2. The docking column 102 and the docking column 202 can reduce the contact area between the hexagonal bolts 4 and the air, thereby preventing the hexagonal bolts 4 from rusting and oxidizing and making it inconvenient to disassemble later. The sealing gasket 3 can be disassembled and replaced by reverse operation.

[0034] The entire operation process is simple and convenient. Compared with the existing high-strength flanges, the utility model can facilitate the replacement and disassembly of the sealing ring gasket through design, enhance the installation stability and convenience of the sealing ring gasket, and improve the overall connection strength of the flange.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
