MULTIPLE PRESSURE REGULATING APPARATUS FOR OFFSHORE PLANT

摘要

The present invention relates to a multiple pressure regulating apparatus for offshore plant including a first pressure control part to control the extent of openness of a pipe line at a first point; and a second pressure control part to control the extent of openness of the pipe line at a second point spaced apart from the first point. The second pressure control part opens the second point with a size smaller than that of which the first pressure control part opens the first point so that pressure can be decreased step by step while marine resources pass through the first point and the second point. According to the present invention, the apparatus can decrease risk that the pipe line is damaged or destroyed due to a drop in temperature by preventing temperature change caused by drop in pressure while marine resources are transferred along the pipe line, and can prevent not only economic loss but also improve productivity in acquiring the marine resources since a transfer amount of the marine resources may not decrease by preventing extraneous matter from being formed in a pipe line.
