Description

Technical Field

[0001] The utility model relates to the technical field of flange installation, in particular to a compression hardware flange capable of improving sealing performance. Background Art

[0002] Flange is a connector, usually used to connect pipes. There are holes on the flange. During installation, the two flanges can be fixed by passing the bolts through the holes on the two flanges and then screwing them together. During installation, in order to avoid leakage in the gap between the two flanges, gaskets are usually added between the two flanges. When the two flanges are installed, the bolts are tightened to drive the two flanges closer together, so that the two flanges squeeze the gaskets, so that the gaskets are pressed and deformed and then pressed against the flanges to avoid leakage in the gap. However, this installation method is a method of clamping the gasket, which is inconvenient to fix the gasket during installation, which is relatively inconvenient. You can also apply sealant on the gasket and then clamp it between the two flanges for installation. When using sealant for installation, the sealant needs to be dry before it can be used. The tighter the clamping between the two flanges, the longer the sealant takes to dry, which is relatively inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] See also Figures 1 to 5 In an embodiment of the utility model, a compression fitting flange capable of improving sealing performance includes two flanges 100, and the inner side walls of the two flanges 100 are fixedly sleeved with a tube body 200, a sealing mechanism 300 is provided between the two flanges 100, and a clamping mechanism 400 is provided between the two tube bodies 200;

[0023] The sealing mechanism 300 includes a rubber ring 310, and a plurality of circular holes 311 are provided on one side of the rubber ring 310. Annular rubber bags 320 are fixedly connected to opposite sides of the rubber ring 310, and the interiors of the two annular rubber bags 320 are connected to the interiors of the plurality of circular holes 311. An annular air guide groove 312 is provided inside the rubber ring 310, and the interior of the annular air guide groove 312 is connected to the interiors of the plurality of circular holes 311. A connecting groove 313 is provided on the outer wall of the rubber ring 310, and the interior of the connecting groove 313 is connected to the interior of the annular air guide groove 312. An annular clamping groove 101 is provided on adjacent sides of the two flanges 100, and the two annular rubber bags 320 are movably clamped in the two annular clamping grooves 101, respectively.

[0024] Specifically, the clamping mechanism 400 is placed between the two tube bodies 200, and the rubber ring 310 is sleeved on the clamping mechanism 400, and then an annular rubber capsule 320 on one side of the rubber ring 310 is inserted into the annular clamping groove 101 on one flange 100 to position and fix the rubber ring 310, and then the other flange 100 is aligned with the other flange 100 and pressed, so that the other annular rubber capsule 320 is automatically clamped into the annular clamping groove 101 on the other flange 100, and then the bolt is inserted into the rubber ring 310. The two flanges 100 are screwed into the holes on the two flanges 100 to fix the two flanges 100, so that the rubber ring 310 is compressed and deformed to seal the two flanges 100. Then the user can use an inflation device such as an air pump to inflate the connecting groove 313 inward, so that the air is simultaneously injected into the two annular rubber bags 320 through the annular air guide groove 312 and the multiple circular holes 311, so that the two annular rubber bags 320 expand and plug the annular grooves 101 that are inserted into each other, thereby improving the sealing effect between the two flanges.

[0025] Embodiment 1

[0026] like Figure 2-5 As shown, in this embodiment, the inner and outer surfaces of the two annular grooves 101 are both inclined surfaces, and a metal tube 330 is fixedly connected inside the connecting groove 313 .

[0027] In the present embodiment, the width of the opening of the cross section of the annular groove 101 is small and the width of the inner wall is large, so that when the annular rubber bag 320 is inflated and expanded, it can fit the shape of the annular groove 101 and be fixed inside the annular groove 101 to prevent the annular rubber bag 320 from escaping from the annular groove 101. The metal tube 330 can facilitate the user to inflate the inside of the rubber ring 310 with the inflation device. After the inflation is completed, the user can use pliers to flatten and bend the metal tube 330 to seal the metal tube 330 to avoid air leakage, thereby facilitating the user to inject air into and seal the rubber ring 310. When the rubber ring 310 needs to be removed, the user can use cutting equipment such as scissors to cut the metal tube 330. The metal tube 330 can be made of common metal materials such as aluminum and iron sheet.

[0029] In specific implementation, the collar 420 is made of rubber. When in use, the user clamps it between the two tube bodies 200. After the two flanges 100 are fixed by bolts, the collar 420 is clamped between the two tube bodies 200 to fix them, thereby improving the sealing effect between the two tube bodies 200.

[0030] Embodiment 2

[0031] On the basis of the first embodiment, the metal strip 430 and the guide hole 440 facilitate the fixing and positioning of the collar 420, so as to facilitate the use of the user.

The plurality of guide holes 440 on the same ring body 410 correspond one to one with the plurality of metal strips 430 on the same side of the collar 420, and the metal strips 430 are slidably engaged in the corresponding guide holes 440, and the guide holes 440 are J-shaped structures.

[0033] In specific implementation, when connecting two flanges 100, the user can insert the metal strip 430 on the ring 420 into the guide hole 440 on a ring body 410, and then the user presses the ring 420 to deform the metal strip 430 on one side along the shape of the adjacent J-shaped guide hole 440, so that the ring 420 is clamped on one ring body 410 through the deformed metal strip 430, and then the user can align the multiple guide holes 440 on the other ring body 410 with the metal strip 430 on the other side of the ring 420 and press it, so that the ring 420 is clamped between the two ring bodies 410 for fixation, so that the ring 420 assists in positioning the two flanges 100, which is convenient for flange installation, and the metal strip 430 is made of a softer and more deformable metal material.
