Embodiment Construction

[0010] Such as figure 1 As shown, the combined quick sealing flange includes a flange end 1 and a blind plate end connected to each other. The flange end and the blind plate end are connected to form an integral structure. The flange end 1 and the blind plate end 2 are respectively provided with A plurality of bolt holes are provided with an annular groove, and the sealing ring in the annular groove is an O-shaped sealing ring (not shown in the figure). The upper end surface and the lower end surface of the flange end 1 and the blind plate end 2 are respectively provided with bolt grooves 3 arranged transversely.

[0011] The present invention chooses to use the BS type flange in the standard number of GB / T4450-1995, which is usually called a combined quick sealing flange, which can realize fast and free conversion of blind-through flanges with a minimum of bolts removed. The combined fast sealing flange has a wide range of applications, and all the ports that need to install th...

Abstract

The invention relates to a combined rapid sealing flange, which comprises a flange end and a blind plate end that are connected to form an integral structure; multiple bolt apertures are made on the flange end and the blind plate end respectively; a sealing groove and a sealing ring are arranged in each bolt aperture; and a bolt groove is arranged transversally on the upper transverse planes and the lower transverse planes of the flange end and the blind plate respectively. Compared with prior art, the combined rapid sealing flange has the advantages of convenient usage and simple operation; the action of dismounting all bolts for replacing the flange is avoided; and the combined rapid sealing flange can be replaced without taking the flange out of a pipeline. The combined rapid sealing flange can be manufactured conveniently; the usage is convenient; the sealing is reliable; and the difficulty for replacing a blind plate is reduced.

Description

Technical field [0001] The invention relates to a flange for the shipbuilding industry, in particular to a combined quick sealing flange. Background technique [0002] The flange is a part that connects the pipe to the pipe, and is usually connected to the pipe end. There are holes on the flange, bolts can be used to make the two flanges tightly connected. At present, in the piping system of ships, there are many pipelines that need to be cut off when not in use and need to be connected when in use. In this case, the use of traditional combined quick-seal flanges requires all bolts to be removed before they can be adjusted. The workload is heavy and it is easy to cause the liquid in the pipeline to flow into the engine room. Summary of the invention [0003] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a combined quick sealing flange, which is not only easy to manufacture, but also easy to use, reducing the difficulty of ...
