Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a flange assembly with a guiding structure. Background Technology

[0002] Clamp connector flanges, also known as clamp flanges, are a special type of flange that does not have bolt holes itself, relying instead on an external clamp to apply locking force for quick connection and sealing. This type of flange typically consists of a pair of flanges, a gasket, and a clamp. The sealing principle is as follows: the two flanges are manually aligned, the gasket is clamped between the sealing faces of the two flanges, and then the clamp bolts are tightened, bringing the two flanges together and compressing the gasket to form a seal. However, existing clamp flanges still have the following shortcomings in application: 1) At least two workers are required to perform the connection operation when connecting flanges. One person needs to align the two flanges and initially fix the sealing gasket, while the other person needs to tighten the clamp bolts. The operation is difficult and wastes human resources.

[0003] 2) Misalignment of the two flanges is prone to occur, which can easily lead to gasket misalignment or damage during connection, resulting in poor sealing performance. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a flange assembly with a guide structure, which has a simple sealing connection operation, can effectively avoid alignment deviation, and can be performed by one person, thus effectively saving manpower.

[0005] The objective of this utility model is achieved through the following technical solution: A flange assembly with a guiding structure includes a first flange and a second flange; The first flange includes a first flange tube body and a first flange plate body fixed to one end of the first flange tube body. A guide tube body is connected to the inner edge of the first flange plate body. The guide tube body is coaxial with the first flange tube body and extends in a direction away from the first flange tube body. The second flange includes a second flange tube body and a second flange plate body fixed to one end of the second flange tube body. The inner side of the second flange is used to connect to the guide tube body and slides with the guide tube body.

[0006] Furthermore, the inner side of the second flange is provided with a front guide ring surface and a rear guide ring surface. One end of the front guide ring surface is connected to the sealing surface of the second flange body, and the other end of the front guide ring surface is connected to the rear guide ring surface. The diameter of the front guide ring surface gradually decreases from the sealing surface of the second flange body to the rear guide ring surface. The rear guide ring surface is used for sliding fit with the outer surface of the guide tube body.

[0007] Furthermore, the end of the guide tube body away from the first flange tube body is provided with an annular fillet, and the annular fillet is located between the outer side surface and the end face of the guide tube body.

[0008] Furthermore, both the first flange body and the second flange body have a trapezoidal structure.

[0009] Furthermore, the sealing surface of the first flange body is provided with a first annular groove, and the sealing surface of the second flange body is provided with a second annular groove.

[0010] Furthermore, the flange assembly also includes a sealing gasket and a clamp. The sealing gasket is used to be disposed between the sealing surfaces of the first flange body and the second flange body, and the clamp is used to lock the first flange and the second flange together.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The flange assembly with a guide structure provided by this utility model allows the guide tube of the first flange to be inserted into the inside of the second flange during sealing connection operations. This allows the second flange to temporarily overlap the guide tube, freeing up the operator's hands to tighten the clamp bolts to lock the first and second flanges. Therefore, one person can perform the sealing connection operation, effectively saving manpower. In addition, the alignment between the two flanges is achieved by inserting the guide tube of the first flange into the inside of the second flange, which is not only simple to operate but also effectively avoids deviation.

A guide tube 103 is connected to the inner edge of the first flange disc 102. The guide tube 103 is coaxial with the first flange tube 101 and extends in a direction away from the first flange tube 101. The second flange 200 includes a second flange tube 201 and a second flange disc 202 fixed to one end of the second flange tube 201. The inner side of the second flange 200 is used to connect to the guide tube 103 and slides in cooperation with it.

[0016] In the flange assembly of this utility model embodiment, the first flange body 102 has a trapezoidal structure, and the second flange body 202 has a trapezoidal structure; the sealing surface of the first flange body 102 is provided with a first annular groove 105, and the sealing surface of the second flange body 202 is provided with a second annular groove 205.

[0017] The flange assembly of this utility model embodiment also includes a sealing gasket and a clamp. The sealing gasket is used to be disposed between the sealing surface of the first flange body 102 and the sealing surface of the second flange body 202. The sealing gasket is usually provided with a protruding structure on both axial sides, which then engages with the first annular groove 105 and the second annular groove 205. The clamp is used to lock the first flange 100 and the second flange 200.

[0018] In the flange assembly of this embodiment, the inner side of the second flange 200 is provided with a front guide ring surface 203 and a rear guide ring surface 204. One end of the front guide ring surface 203 is connected to the sealing surface of the second flange body 202, and the other end of the front guide ring surface 203 is connected to the rear guide ring surface 204. The diameter of the front guide ring surface 203 gradually decreases from the sealing surface of the second flange body 202 to the rear guide ring surface 204. The rear guide ring surface 204 is used for sliding engagement with the outer surface of the guide tube body 103. With this configuration, the guide tube body 103 of the first flange 100 can be easily inserted into the inner side of the second flange 200 through the front guide ring surface 203, and the second flange 200 can be stably overlapped on the guide tube body 103 through the rear guide ring surface 204.
