Description

Blind plate and intelligent management method thereof Technical Field The application relates to the technical field of blind plates, in particular to a blind plate and an intelligent management method. Background Blind plates are a critical safety isolation component in industrial piping systems, which are essentially a solid, circular plate without a central hole, with bolt holes drilled in its outer edges, and the main function of the blind plates is to permanently or temporarily, completely block the flow of media within the piping, forming a reliable isolation barrier. The blind plate is applied to 1, safety isolation, namely, when equipment or a pipeline section needs to be overhauled and maintained, the blind plate is installed to ensure complete isolation from a running system, so that toxic, harmful, inflammable and explosive mediums are prevented from being leaked accidentally, and the safety of personnel is ensured. 2. System separation, in new, expanded or retrofit projects, is used to isolate the portions of different sub-systems or stage construction from the main system. 3. Pressure test, in which a blind plate is used for plugging at the tail end of a system to establish test pressure when a pipeline strength test or a tightness test is carried out. 4. And (3) plugging the waste port, namely permanently plugging a pipeline branch port, a discharge port or a reserved port which are not used any more. In the related art, the safety production accidents are possible to happen due to the fact that the blind plate is additionally arranged in wrong positions and the blind plate is extracted in wrong positions, and safety measures are not implemented in place in the process of extraction and blockage, and related accident events at home and abroad are fully proved.
