Liquid fluid conveying pipeline cleaning opening setting method and structure

Abstract

The liquid fluid conveying pipeline cleaning opening setting method and structure are suitable for straight pipes and also suitable for elbows, a pipeline cleaning opening is blocked by arranging a connecting pipe in the pipeline cleaning opening and an end cover in the connecting pipe, the part between the connecting pipe and a pipeline are sealed, the connecting pipe and the end cover are in clearance fit, one ends, far away from the cleaning opening, of the connecting pipe and the end cover are sealed, the shapes of the end surfaces, located in the pipeline, of the connecting pipe and the end cover are kept consistent with the shape of the inner surface of the pipeline, so that the smooth transition connection in the whole pipe is ensured, thick liquid is not hung, the pressure is stable, and a liquid fluid can smoothly flow in the pipe.

Description

technical field [0001] The invention relates to a setting method and structure of a pipeline cleaning port, in particular to a setting method and structure of a liquid fluid delivery pipeline cleaning port. Background technique [0002] When the fluid is conveyed in the pipeline, it is necessary to ensure the smooth flow of the pipeline so that the fluid can pass through smoothly. For example, in the paper production process, the raw materials need to be crushed into pulp, and then the pulp is transported to the forming equipment, and this process needs to ensure that the pulp will not be polluted. Therefore, the existing paper mills are becoming more and more mechanized to reduce manual participation. To improve efficiency and reduce labor costs, a special conveying device is used to send pulp directly to the forming equipment through pipelines. In the process of pulp transportation, if the pipeline is used for a long time, some pulp will stick to the inside of the pipelin...

Problems solved by technology

[0005] Although the above-mentioned patent also opens on the pipe, the pipe cover plate in the scheme is only a part of the original pipe, and a part will be lost during the cutting process, so the direct gap between the pipe cover plate and the pipe is relatively large, and the pipe cover plate and the pipe The space formed between the sealing plate and the cover plate is large, and the pipe cover plate is blocked from the pipe by welding the support plate on the pipe cover plate to prevent it from falling, so the contact part between the pipe cover plate and the pipe cannot be guaranteed. Smooth, there may be steps, it can only be used in environments with low requirements for sealing and flow rate accuracy, and the document also states that it is used for garbage transportation under negative pressure environments, and cannot be used in environments with high sealing requirements and The smoothness of the pipeline requires high liquid fluid delivery, so it needs to be improved
