Description

Novel stainless steel flange

Technical Field

The utility model belongs to the technical field of the flange, especially, relate to a novel stainless steel flange.

Background

A flange, also known as a flange collar or flange. The flange is a part for connecting the shafts and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The flange connection or flange joint is a detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The pipeline flange is a flange for piping in a pipeline device, and is used on equipment to be an inlet and outlet flange of the equipment. The flanges are provided with holes, and the two flanges are tightly connected through bolts. The flanges are sealed with gaskets. The flange is divided into a threaded connection (screw thread connection) flange, a welding flange and a clamping flange. The flanges are used in pairs, the low-pressure pipeline can be screwed with the flanges, and the flanges are welded under the pressure of more than four kilograms. And a sealing gasket is arranged between the two flanges and then is fastened by bolts. The flanges of different pressures have different thicknesses and they use different bolts. When the water pump and the valve are connected with a pipeline, the parts of the equipment and equipment are also made into corresponding flange shapes, which are also called flange connection. The connecting parts which are connected by using bolts at the peripheries of two planes and are closed at the same time are generally called flanges, and for example, the connecting parts of the ventilating duct can be called flange parts. However, the connection is only a part of equipment, such as the connection between a flange and a water pump, and the water pump is not easy to be called as a flange part. The small-sized valve can be called as a flange part.

When some multi-pipeline structural connection is carried out, the existing flange cannot meet the use requirement and the connection strength requirement.

Furthermore, the liquid inlet pipeline flange is a flat welding flange.

Further, the size of the first through hole is consistent with that of the second through hole.

Furthermore, the positions and the sizes of the threaded holes correspond to those of the threaded through holes one to one.

Furthermore, the female flange and the male flange are both made of stainless steel.

About implementing the utility model discloses a beneficial technological effect does: the utility model discloses a cooperation between each component among the above technical scheme can realize the connection between six root pipelines at most, makes things convenient for the connection of the pipeline in different positions, the sub-flange is provided with the stiffening rib has improved the intensity of flange, has guaranteed the utility model discloses security during the use, the utility model has the characteristics of simple structure, practicality are strong, simple to operate.
