Description

Technical Field

[0001] The utility model relates to the technical field of flanges, and more specifically, to a flange with good sealing performance. Background Art

[0002] A flange, also known as a flange boss disc or a flange, is a part used to connect shafts to each other. It is an element for connecting or sealing two pipes, valves, containers or devices. Generally, a flange consists of two flange discs, which are connected by bolts and use sealing materials to achieve the sealing effect between pipes, valves or devices.

[0003] For example, Chinese Patent CN219755649U discloses a flange with good sealing performance, which includes a flange disc. An installation hole is provided on one side of the flange disc, a sealing mechanism is arranged on one side of the flange disc, and a filtering mechanism is arranged on the other side of the flange disc. This can prevent the deformation and dislocation of the sealing ring when the sealing ring is squeezed, thereby affecting the sealing effect of the sealing ring. In this way, every time the flange disc is used to connect a water pipe, the sealing ring is in a proper position, making the sealing effect between the flange discs better.

[0004] However, while the above-mentioned flange achieves sealing, it cannot clamp the front flange disc and the rear flange disc together to form a tight connection at the interface, reducing the connection tightness between the flange and the connected water pipe. It may cause medium leakage after long-term use, reducing the safety of the entire pipeline system.

[0005] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0006] In view of the problems in the related art, the utility model provides a flange with good sealing performance to overcome the above-mentioned technical problems existing in the prior related art.

[0007] Therefore, the specific technical solution adopted by the utility model is as follows:

[0008] A flange with good sealing performance includes a front flange disc. A rear flange disc is arranged on one side of the front flange disc. A plurality of groups of connection holes are provided at one end of both the front flange disc and the rear flange disc. Sealing components are arranged inside both the front flange disc and the rear flange disc. A clamping component is arranged between the front flange disc and the rear flange disc.

[0009] Furthermore, in order to achieve the purpose of waterproof sealing through the waterproof sealing sheet, and at the same time, the waterproof sealing sheet can always be in contact with the connecting water pipe under the action of the compression spring, thereby effectively increasing the connection tightness between the front flange and the rear flange and the connecting water pipe, achieving the waterproof sealing effect. The sealing assembly includes mounting grooves opened inside the front flange and the rear flange. A waterproof sealing ring is arranged inside the mounting groove. An annular groove is opened on one side of the waterproof sealing ring. A number of groups of compression springs are arranged inside the annular groove, and one end of the compression spring is connected to the inner wall of the mounting groove; a number of groups of waterproof sealing sheets are evenly arranged on the other side of the waterproof sealing ring.

[0010] Furthermore, in order to be able to fasten the front flange and the rear flange together under the action of the clamping shaft and the groove, form a tight connection at the interface, and thereby effectively prevent the leakage of the medium and improve the safety of the entire pipeline system, the clamping assembly includes jacks symmetrically installed at one end of the front flange and the rear flange. A clamping shaft is arranged inside one of the jacks; semi-circular holes are opened on the outer sides of the front flange and the rear flange. An adjusting rod is arranged inside the two semi-circular holes. A knob is arranged on the outer side of the adjusting rod; a groove matching with the clamping shaft is opened on the outer side of the adjusting rod, and the groove is an arc-shaped structure.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. The structure of the present utility model is simple and the operation is convenient. By setting the clamping assembly, the front flange and the rear flange can be clamped together under the action of the clamping shaft and the groove, form a tight connection at the interface, and thereby effectively prevent the leakage of the medium and improve the safety of the entire pipeline system.

[0013] 2. By setting the sealing assembly, the present utility model can achieve the purpose of waterproof sealing through the waterproof sealing sheet, and at the same time, the waterproof sealing sheet can always be in contact with the connecting water pipe under the action of the compression spring, thereby effectively increasing the connection tightness between the front flange and the rear flange and the connecting water pipe, achieving the waterproof sealing effect.
