Description

Stainless steel combination flange

Technical Field

The utility model relates to a combination flange technical field especially relates to a stainless steel combination flange.

Background

The flange is a connecting tool, and the flange connection refers to the detachable connection of a group of combined sealing structures formed by the mutual connection of the flange, a gasket and a bolt. The flange is divided into a threaded connection (screw thread connection) flange, a welding flange and a clamping flange. The flange connection has the advantages of good connection sealing performance, stable structure, high strength, convenient use, low cost and the like, and is widely applied to the industries such as the building industry, urban water supply, boiler pressure vessels, the petroleum industry, gas supply, the chemical industry, the food industry, fire fighting, the pharmaceutical industry, power stations, water conservancy, heating ventilation and the like. The existing flange does not have a filtering function and cannot fully meet the industrial requirements.

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.
