VALVE FOR STEAM COMPRESSION PLANT Russian patent published in 2013 - IPC F16K11/74 F25B41/04 

FIELD: machine building.

SUBSTANCE: invention refers to valve containing inlet branch pipe, to which fluid medium is supplied, and at least two outlet branch pipes, each of which is connected via fluid medium to flow path; with that, at least two of the above flow paths are located parallel as to fluid medium; each outlet branch pipe supplies fluid medium to one of the flow paths. Besides, valve includes the first valve part (1), in which there are at least two flow passages (2); each flow passage (2) is connected as to fluid medium to one of the above outlet branch pipes and the second valve part (3), in which there is at least one main flow passage (4) and at least one auxiliary flow passage (5, 6, 7). Main flow passage or passages (4) and auxiliary flow passage or passages (5, 6, 7) are connected as to fluid medium to the above inlet branch pipe; with that, the first valve part (1) and the second valve part (3) are installed so that they can be moved relative to each other so that mutual position of the first (1) and the second (3) valve parts determines fluid medium flow between inlet branch pipe and each of outlet branch pipes through flow passages (2, 4, 5, 6, 7) of the first valve part (1) and the second valve part (3). Each main flow passage (4) sets fluid medium flow rate that sufficiently exceeds fluid medium flow rate specified with each of auxiliary flow passages (5, 6, 7) so that if main flow passage of the second valve part is connected as to fluid medium to this flow passage of the first valve part, then, main part of fluid medium supplied through inlet branch pipe enters the flow path that is connected as to fluid medium to this flow passage, and if auxiliary flow passage of the second valve part is connected as to fluid medium to this flow passage of the first valve part, then, smaller part of fluid medium supplied through inlet branch pipe enters the flow path that is connected as to fluid medium to this flow passage.

EFFECT: improvement of plant.
