the system of high reliability for protection from excess pressure (HIPPS) for the line of water environment

摘要

the invention relates to a system of high reliability for protection from excess pressure (HIPPS) (1) containing u0434u0432u0443u0445u043fu043eu0437u0438u0446u0438u043eu043du043du044bu0439 valve (2) includes housing (10), i. that u0432u043fu0443u0441u043a (11) and the output (12) and the channel (13) for the passage of fluid from the inlet to the manufacturing environment, and with the closing element (14); a hydraulic executive the mechanism (3), a control element (23).which u043au0438u043du0435u043cu0430u0442u0438u0447u0435u0441u043au0438 connected with the closing element (14); u043fu0435u0440u0435u043au043bu044eu0447u0430u0435u043cu044bu0439 block (4) of the hydraulic environment, which in the active state of a dove in the control surface (25) of the element (23), and a passive state or operating pressure control surface (25); sensormeasuring pressure of water environment on the flow below the output (12); and a logical device which compares the pressure below the critical value of the flow, u043fu0435u0440u0435u043au043bu044e for the block of the hydraulic environment in active state, so that the closing element remains in the position of the opening, at any time, when the right of less critical valueand a switching block for hydraulic environment in passive condition to move the closing element in a closing position, or to stay in this p u043eu043bu043eu0436u0435u043du0438u0438 at any moment of time, when the pressure exceeds the critical value.the invention proposes that on the surface of the element opposite to the surface, bad pressure fluid environment, u043du0430u0445u043eu0434u044fu0449 u0435u0439u0441u044f below on the flow, resulting in pressure pushes the closing element in a closing position.
