Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flanges and relates to a flange which is easy to disassemble. Background Art
[0002] Most combination flanges in the prior art adopt a modular design, which means that it consists of multiple parts that can be separated or reassembled through quick connection or easy disassembly mechanisms. This design not only simplifies the installation and disassembly process, but also facilitates maintenance and replacement. Some combination flanges are designed with special disassembly tools or methods, allowing users to complete the disassembly work easily and safely. Combination flanges play an important role in certain applications, especially in situations where flexible connections are required. However, when faced with high-pressure gas, its pressure bearing capacity becomes a consideration that cannot be ignored. If the combination flange cannot withstand high-pressure gas, it may cause a series of problems.
[0003] One of the main functions of flanges is to ensure the tightness of gas or liquid. In the case of high-pressure gas, if the flange cannot withstand the pressure, it may cause the sealing gasket or sealing ring to deform, causing gas leakage. This not only affects the performance of the equipment, but may also cause safety hazards to operators and the environment.
[0004] Under the action of high-pressure gas, the flange connection may move or deform slightly, resulting in a loose connection. Long-term operation in this state may cause the connection to loosen or become damaged, increasing the frequency of maintenance and replacement.
[0005] High-pressure gas leaking through the flange will not only affect the normal flow of gas, but may also affect the performance of the equipment. For example, in pneumatic equipment, leakage may cause insufficient gas flow, which in turn affects the normal operation of the equipment and the stable operation of the production line.
[0006] Under the repeated action of high-pressure gas, the flange and its accessories (such as bolts, nuts, etc.) may become fatigued and damaged. This not only shortens the service life of the equipment, but may also cause sudden equipment failure or safety accidents.
[0007] Gas leakage not only affects the operating environment inside the equipment, but may also have a negative impact on the external environment. For example, the leaked gas may pollute the surrounding atmosphere.
[0008] In summary, the pressure bearing capacity of the combined flange is the key when facing high-pressure gas. If it cannot effectively withstand the pressure, it will cause a series of problems such as sealing failure and decreased connection stability, affecting the performance of the equipment, increasing maintenance costs and posing a threat to the environment and personnel safety. Therefore, a flange that is easy to disassemble is urgently needed to solve the above problems. Utility Model Content

[0029] A lower flange 160 is provided on the outer side of the lower end of the lower connecting seat 170, and an inner cavity 190 is provided on the inner side of the lower flange 160. A group of piston rings 230 are provided on the inner sides of the two groups of connecting seats 170.

[0030] There are two groups of connecting heads 100, and one group of connecting heads 100 is provided at the upper end of the upper flange 120 and the lower end of the lower flange 160. The two groups of connecting heads 100 are respectively integrated with the upper flange 120 and the lower flange 160. The connection effect of the upper flange 120 and the lower flange 160 can be enhanced by using the connecting heads 100.
[0031] The upper flange 120 and the lower flange 160 have the same specifications, and the upper flange 120 and the lower flange 160 are connected and fixed by four groups of support rods 150 and several groups of connecting nuts 140. External threads are provided on the outer sides of the upper and lower ends of the support rods 150. Each group of support rods 150 is threadedly connected with four groups of connecting nuts 140. The four groups of support rods 150 can be used to support and connect the upper flange 120 and the lower flange 160.
[0032] There are two groups of connecting seats 170, and the two groups of connecting seats 170 are respectively integrated with a group of pressure-reducing cylinders 180 on the upper and lower sides. A corrugated structure is provided in the middle position inside the pressure-reducing cylinder 180. The pressure-reducing cylinder 180 is made of a metal material and can further relieve the pressure between the upper flange 120 and the lower flange 160 through the pressure-reducing cylinder 180.
[0033] The two groups of connecting seats 170 have the same structure and are sealed and connected to the lower end of the upper flange 120 and the upper end of the lower flange 160 respectively. The interior of the inner cavity 110 is interconnected with the interior of the upper connecting seat 170, and the interior of the inner cavity 2 190 is interconnected with the interior of the lower connecting seat 170.
[0034] The interior of the pressure relief cylinder 180 is a hollow structure. The interiors of the two groups of connecting seats 170 are interconnected through the interior of the pressure relief cylinder 180 . A group of annular concave grooves are provided in each group of connecting seats 170 .
[0035] Each group of annular concave grooves is engaged and connected with a group of seats 210. The seats 210, connecting tubes 220, inner shells 200 and a group of pistons constitute a group of pressure-bearing reinforcement mechanisms. In addition, a group of pressure-bearing reinforcement mechanisms are provided inside the two groups of connecting seats 170. The seats 210 can be quickly connected by using the annular concave grooves. At the same time, the pressure-bearing reinforcement mechanisms can effectively increase the pressure inside the two groups of connecting seats 170.
[0036] See also Figure 1-Figure 4 As the first embodiment of the utility model: In order to solve the problem that under the action of high-pressure gas, the connection part of the flange may move or deform slightly, resulting in an unstable connection. Long-term operation in this state may cause the connection part to loosen or be damaged, increasing the frequency of maintenance and replacement. First, the staff connects the external high-pressure gas inlet end to the upper flange 120 by bolts, and seals and fits with the inner side of the upper end connecting head 100, and then connects the external gas outlet end to the lower flange 160 by bolts, and seals and fits with the inner side of the lower end connecting head 100, and forms a diversion path between the external high-pressure gas inlet end and the external gas outlet end. Subsequently, when the high-pressure gas enters the inner side of the connecting head 100, the high-pressure gas enters the connecting hole 240 through the inner cavity 110, and the high-pressure gas enters the connecting tube 220 through the connecting hole 240. Please refer to Figure 4 The connecting tube 220 can further enhance the pressure bearing capacity of the connecting seat 170 inside the connecting seat 170. At the same time, since each group of connecting seats 170 is provided with a group of annular concave embedding grooves, each group of annular concave embedding grooves is embedded and connected with a group of embedding seats 210, and the embedding seats 210 can provide a pressure stabilizing effect for the connecting tube 220.
[0037] See also Figure 1-Figure 4, as the second embodiment of the utility model: based on the description in the above embodiments, further, since there are two groups of connecting seats 170, and the two groups of connecting seats 170 are respectively integrated with a group of pressure-reducing cylinders 180 on the upper and lower sides, a corrugated structure is provided in the middle position inside the pressure-reducing cylinder 180, and the pressure-reducing cylinder 180 is made of a metal material. When the high-pressure gas enters the pressure-reducing cylinder 180 through the bottom of the connecting cylinder 220, the pressure-reducing cylinder 180 can release the expansion effect of the high-pressure gas, and at the same time prevent the high-pressure pressure from directly pressurizing the upper flange 120 and the lower flange 160, thereby causing damage to the upper flange 120 and the lower flange 160, thereby reducing the use loss cost.
[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
