Embodiment Construction
[0011] Such as figure 1 and figure 2 As shown, the tube sheet provided with a hole sealing structure includes a tube sheet body 1, and the center of the tube sheet body 1 is provided with a central hole 2 for connecting pipes. The tube sheet body 1 is provided with a plurality of bolt holes 3, each The bolt holes 3 are provided with annular grooves 4, which are located in the bolt holes 3 close to the outer surface of the tube plate body 1, and the annular grooves 4 are provided with sealing rings (not shown in the figure).
[0012] In this embodiment, the sealing ring in the annular groove 4 of the bolt hole 3 is an O-shaped sealing ring with a steel wire skeleton; the tube plate body 1 is welded with the pipeline to form a sealing structure.
[0013] The present invention installs an O-shaped sealing ring with a steel wire skeleton in the annular groove 4 of the bolt hole 3, which is not only safe and reliable to use, but also easy to process and manufacture, convenient to...

The invention relates to a pipe plate provided with hole sealing structures. The pipe plate comprises a pipe plate body; a center hole for connecting with a pipe is formed in the center of the pipe plate body; multiple bolt holes are formed in the pipe plate body; annular grooves are formed in all the bolt holes; and sealing rings are arranged in the annular grooves. The pipe plate body is welded with the pipe to form a sealing structure; and the sealing rings in the annular grooves of the bolt holes are O-shaped sealing rings with steel wire skeletons. Compared with the prior art, the hole sealing structures are arranged in the bolt holes of the pipe plate, and the O-shaped sealing rings with the steel wire skeletons are mounted in the holes, so that the use is safe and reliable, the production is convenient, the use is convenient, the probability of a medium leaking through the bolt holes of the pipe plate is greatly reduced, and the sealing is reliable.
Description
technical field [0001] The invention relates to an end face sealing plate for a pipeline, in particular to a tube plate provided with a hole sealing structure. Background technique [0002] The tube sheet is a component used to connect pipes or pipes to other components, and is usually installed and connected to the pipe end. There are holes on the tube plate, which can pass through bolts, also known as bolt holes. Through the connection of the tube sheet, the two pipes can be tightly connected to form a seal. At present, when tube sheets are used for connection and sealing in existing industrial pipelines, gaskets are usually added between the tube sheets or between the tube sheets and other components, and then the bolts are tightened for sealing. Such a seal can generally maintain a good sealing effect. However, for pipeline equipment that needs to be disassembled frequently or has corrosion and vibration, sometimes small cracks appear in the gasket, and the medium lea...
