Description

Technical Field

[0001] This application relates to the technical field of flanges, and more specifically, to a flange assembly. Background Art

[0002] A flange, also known as a flange convex disc or flange, is a part used to connect shafts to each other and is used for connecting between pipe ends; there are also flanges used at the inlets and outlets of equipment for connecting between two pieces of equipment, such as a reducer flange.

[0003] According to the search, a Chinese patent with the publication number CN213479440U discloses a flange assembly, which includes a first flange and a second flange. In the middle of one side of the first flange, there is a plugging mechanism, and in the middle of one side of the second flange, there is a groove mechanism. The plugging mechanism and the groove mechanism fit together. The plugging mechanism includes a first plugging ring and a second plugging ring, and the groove mechanism includes a first slot hole and a second slot hole. There is an annular groove on the first flange, and a protruding ring is provided on the second flange. The protruding ring and the annular groove correspond and fit together. The first plugging ring and the first slot hole are in close contact with each other, and the second plugging ring and the second slot hole are in close contact with each other, which not only increases the contact surface between the plugging mechanism and the groove mechanism, ensures the tight connection effect, but also guarantees the firmness and reliability of the plugging mechanism. The protruding ring and the annular groove are tightly connected together, further increasing the tight connection reliability between the first flange and the second flange, and avoiding the occurrence of fluid leakage.

[0032] The following will Figures 1-4 further elaborate on the present application in detail.

[0033] Please refer to Figures 1-4 , a flange assembly, including a main body module 100 and a connection module 200. The main body module 100 includes a first flange 110. A second flange 120 is provided on one side of the first flange 110. A first sleeve 130 and a second sleeve 140 are respectively provided on the opposite sides of the first flange 110 and the second flange 120. The connection module 200 is arranged between the first flange 110, the second flange 120, the first sleeve 130 and the second sleeve 140. The connection module 200 includes a disassembly and assembly component 210 provided on the first flange 110 and the second flange 120, and the two disassembly and assembly components 210 are respectively connected to the first sleeve 130 and the second sleeve 140. A sealing component 220 is provided on the second flange 120, and a fixing component 230 is provided between the first flange 110 and the second flange 120.

[0034] Through the setting of the disassembly and assembly component 210, the present flange assembly can replace sleeves of different sizes, thereby improving the applicability of the present flange assembly. Through the setting of the sealing component 220, the sealing performance between the first flange 110 and the second flange 120 can be increased. Through the setting of the fixing component 230, the first flange 110 and the second flange 120 can be connected and fixed.

[0035] The disassembly and assembly component 210 includes two clamping grooves 211 respectively opened on the opposite sides of the first flange 110 and the second flange 120. A snap ring 212 is movably clamped inside the two clamping grooves 211. The first sleeve 130 and the second sleeve 140 are respectively fixedly connected to the inner sides of the two snap rings 212. The disassembly and assembly component 210 further includes two annular grooves 213 respectively opened on the opposite sides of the two snap rings 212. A first sealing ring 214 is movably clamped inside the two annular grooves 213. The disassembly and assembly component 210 further includes two groups of fixing pins 215 respectively threadedly connected inside the two snap rings 212, and the two groups of fixing pins 215 respectively extend into the first flange 110 and the second flange 120.

[0036] By turning out the fixing pin 215 from the snap ring 212 and the first flange 110, and then taking out the snap ring 212 outward, the snap ring 212 can be withdrawn from the clamping groove 211, so that the first sleeve 130 can be disassembled, and then it is convenient to replace sleeves of different sizes.

[0037] The sealing assembly 220 includes a docking groove 221 opened on one side of the second flange 120. A second sealing ring 222 is arranged inside the docking groove 221, and one end of the first sleeve 130 is movably inserted into the docking groove 221 and abuts against the second sealing ring 222.

Nuts 232 are arranged on the plurality of connecting pins 231, and the plurality of nuts 232 all abut against the second flange 120.

[0038] When the first flange 110 and the second flange 120 are docked and assembled, one end of the first sleeve 130 will be inserted into the docking groove 221 and abut against the second sealing ring 222, so that the sealing performance between the first flange 110 and the second flange 120 can be increased. By inserting the connecting pin 231 between the first flange 110 and the second flange 120, and then threadedly connecting the nut 232 to the connecting pin 231 and abutting against the second flange 120, the first flange 110 and the second flange 120 can be connected and fixed.

[0039] The implementation principle of the embodiment of the present application is as follows: When it is necessary to replace sleeves of different sizes, the fixing pin 215 can be rotated to withdraw from the first flange 110 and the snap ring 212, so that the fixing of the snap ring 212 can be released. Then, the first sleeve 130 is pulled outward, and the first sleeve 130 will drive the snap ring 212 to withdraw from the clamping groove 211, so that the first sleeve 130 can be disassembled, and then it is convenient to replace sleeves of different sizes. Through the setting of the first sealing ring 214, the sealing performance between the snap ring 212 and the first flange 110 can be increased. Through the setting of the second sealing ring 222, the sealing performance between the first flange 110 and the second flange 120 can be increased. Through the cooperation of the connecting pin 231 and the nut 232, the first flange 110 and the second flange 120 can be connected and fixed.
