Description

Piston Valve Apparatus The present invention relates to a piston valve device, and more specifically, to a piston valve device capable of resolving the stagnation of stirring of organic matter within a chamber. Recently, the problem of food waste disposal has been increasing due to environmental issues. As organic waste, food waste can be recycled into animal feed, compost, and biogas through intermediate processing. Pipes or chambers are required as a space for the hydrolysis of organic waste. Generally, pipe flanges are essential to connect valves to pipes or chambers, but this creates dead space. If the medium remains stagnant in this dead space for an extended period, it reduces accuracy or lowers the yield when collecting samples from the chamber or pipe. Alternatively, there is a problem where the sample hardens, making it difficult to discharge. When using a ball valve to discharge hydrolyzed organic waste to the outside by stirring it inside the reactor, there is a problem in that complete hydrolysis (stirring) does not occur due to the presence of dead space where stirring does not take place when the valve is mounted at the bottom of the reactor. Therefore, there is a need to improve this. The background technology of the present invention is disclosed in Korean Patent No. 10-0880269 (registered on January 16, 2009, title of invention: Multi-valve device).
