Description

Automated Valve Leakage Inspection System The present invention relates to an automated valve leakage and leak inspection system, and more specifically, to an automated valve leakage and leak inspection system that automatically performs a series of processes to check for leakage and leaks in a valve using hydraulic or pneumatic pressure to inspect whether a valve opening and closing a flow path is defective. Generally, the fluid path is formed to move in one direction, allowing the fluid to move from one point to another. This involves installing fluid flow piping to transport fluid to the location where it is needed, allowing the fluid to travel along the installed channels and be supplied at that location; this can be utilized in various applications, such as workplaces and domestic sewage. However, rather than simply moving the fluid from one point to another, it must be possible to regulate the amount supplied and the amount moved by restricting the movement of the fluid; to this end, it is common practice to equip the piping with valves capable of selectively opening and closing the flow path. However, valves that open and close the flow path must be able to withstand pressure from a large amount of fluid, and since they cannot perform their function properly if the gaps are not sealed, it is essential to inspect whether the valve can withstand hydraulic or pneumatic pressure and whether water or air is leaking out. As such, in order to inspect for valve leakage, it is essential to perform a process of applying a certain amount of water or air pressure to check whether leakage is occurring on the opposite side of the valve; this is also important for preventing various accidents caused by valves. However, various problems could exist, such as leaks occurring in extremely small amounts that were impossible to visually confirm, or leaks caused by worker error during the separation process being deemed normal and shipped. Therefore, various methods are being devised to ensure that no errors occur even while performing a series of processes that are difficult to visually verify during the work process, and means are needed to address this. The summary described above, as well as the detailed description of the preferred embodiments of the present application described below, will be better understood when read in conjunction with the accompanying drawings.
