Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a portable coal slurry cut-off valve. Background Art

[0002] Coal slurry conveying systems play a vital role in mining operations, transporting coal slurry, a mixture of coal powder and water, extracted from the mine, to a distant processing plant or storage location through a series of pipelines. In this process, an efficient and reliable valve system is needed to manage and control the flow of coal slurry to ensure the continuity and safety of the conveying process. Especially in the event of mechanical failure or regular system maintenance, it is crucial to be able to quickly cut off the flow of coal slurry, which not only helps prevent environmental pollution caused by coal slurry leakage, but also reduces economic losses caused by system downtime. Therefore, these valves are not just simple switching devices, they are key components to ensure smooth operation of the entire coal slurry conveying system.

[0003] Traditional coal slurry shut-off valves are mostly fixed and are usually installed at specific locations in mining pipeline systems to control and manage the flow of coal slurry in fixed transportation routes. This configuration performs well in long-term stable operating environments because it can reliably perform its closing or opening functions to ensure that the coal slurry flows as planned. However, in prospecting, testing new mining areas, or mines under construction, these fixed valves are not flexible enough because they cannot quickly adjust their positions or flow rates according to changes on site. For example, it is impossible to effectively respond to pipeline re-layouts caused by terrain changes, or after discovering new ore veins, it is impossible to adjust the pipeline system in time to start a new coal slurry transportation route. In addition, fixed valves cannot adjust the flow rate according to fluctuations in actual output during mining, which can cause bottlenecks or overloads in the coal slurry transportation process, affecting the production efficiency and safety of the entire mine.
