Description
Technical Field
The invention relates to the technical field of flange plate manufacturing, in particular to a firm and durable flange plate.
Background
Flanges, i.e. flanges, which are parts for interconnecting pipes, are connected to the pipe ends, and flanges at the inlet and outlet of equipment are also used for the connection between two pieces of equipment, such as reducer flanges. The flange is provided with a pipe connecting port for connecting a pipeline, a plurality of bolt holes are distributed on the flange, the two flanges are tightly connected through bolts, and the flanges can be sealed by gaskets.
The engineering pipeline can be in a vibration state during working, and at the moment, the connection of the flanges needs to be firmer and more durable than the common flanges, so that more force can be borne, and the separation of the connecting pipelines is caused if the flanges are not broken.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the firm and durable flange plate, which is firm in connection and ensures the stability of pipeline connection.
In order to achieve the purpose, the invention discloses a firm and durable flange plate which comprises a pipe body, reinforcing ribs, bolt holes, a front flange, a pipe connecting port and a rear flange, wherein the centers of the front flange, the rear flange and the pipe body are the pipe connecting port, the front flange and the rear flange are connected through the pipe body, a plurality of bolt holes are distributed in the front flange, the bolt holes are positioned on the periphery of the pipe connecting port, the front flange and the rear flange are directly connected with the reinforcing ribs, and the reinforcing ribs are fixed on the periphery of the pipe body.
The beneficial effect of adopting above-mentioned technical scheme is: the reinforcing ribs are arranged between the front flange and the rear flange to increase the strength of the flange joint, so that the connection is firmer and the stability of pipeline connection is ensured.
Furthermore, one end of the inner side of the rear flange is provided with a circle of shock absorption pad. Some pipelines are in the environment of vibrations, and the snubber block can play the effect of buffering shock attenuation to the junction of pipeline, improves life.
Further, the shock pad is made of rubber and is fixed through bolts. The rubber can freely determine the shape, has large internal friction and good damping effect, and is beneficial to crossing a resonance area and attenuating high-frequency vibration and noise; the maintenance is easy; the quality is little, and installation and dismantlement are convenient.
In addition, the outer surfaces of the front flange and the rear flange are bonded with protective layers. The protective layer is additionally arranged on the outer surface of the flange body, so that the corrosion resistance and the wear resistance of the flange plate are effectively improved, the flange plate is favorable for being used in a severe environment, and the service life of the flange plate is prolonged.
Further, the protective layer material is polytetrafluoroethylene. The protective layer can be made of various plastics or other anticorrosive materials, and preferably polytetrafluoroethylene is waterproof, and has good anticorrosive performance and high wear resistance.

In another embodiment of the present invention, as shown in fig. 1, a ring of shock absorbing pad 7 is disposed at one end of the inner side of the rear flange 6. Some pipelines are in the environment of vibrations, and the snubber block can play the effect of buffering shock attenuation to the junction of pipeline, improves life.
In another embodiment of the present invention, as shown in fig. 1, the shock absorbing pad 7 is made of rubber and fixed by bolts. The rubber can freely determine the shape, has large internal friction and good damping effect, and is beneficial to crossing a resonance area and attenuating high-frequency vibration and noise; the maintenance is easy; the quality is little, and installation and dismantlement are convenient.
In another embodiment of the present invention, as shown in fig. 1, a protective layer is adhered to the outer surfaces of the front flange 4 and the rear flange 6. The protective layer is additionally arranged on the outer surface of the flange body, so that the corrosion resistance and the wear resistance of the flange plate are effectively improved, the flange plate is favorable for being used in a severe environment, and the service life of the flange plate is prolonged.
In another embodiment of the present invention, as shown in fig. 1, the material of the protective layer is polytetrafluoroethylene. The protective layer can be made of various plastics or other anticorrosive materials, and preferably polytetrafluoroethylene is waterproof, and has good anticorrosive performance and high wear resistance.
