The present invention is a steam conditioning valve (12) for use in simul- taneousiy reducing temperature and pres- sure in a superheated steam line. The invention provides a butterfly-type valve with superheating water nozzles (26) oriented on its downstream face (22). In the preferred embodiment illustrated valving (38) is included to control the flow of water to each of the nozzles selec- tively. The present invention provides an improved steam conditioning valve which is both simpler and more economic than existing steam conditioning valves or the combination of pressure reducing valves and desuperheaters.
L'invention concerne un robinet de conditionnement de vapeur (12) servant à abaisser simultanément la température et la pression dans un conduit de vapeur surchauffé. L'invention décrit un robinet de type papillon comportant des gicleurs d'eau de désurchauffage (26) orientés sur sa face aval (22). Dans le mode de réalisation préféré et illustré, la robinetterie (38) permet de réguler le débit d'eau alimentant sélectivement chacun des gicleurs. Ce robinet amélioré de conditionnement de vapeur est à la fois plus simple et plus économique que ceux de l'état actuel de la technique ou que la combinaison de robinets de limitation de pression et de désurchauffeurs.
