Abstract

Una válvula de compuerta adaptada para asentamiento posterior de vástagotiene un conjunto de vástago y sombrerete con un anillo de cojineterotatorio al cual se fija de manera liberable el vástago durante lasoperaciones normales de abertura y cierre de la compuerta. Durante elasentamiento posterior, el vástago es liberado del anillo de cojinete y elanillo de cojinete es fijado a la tapa de sombrerete, permitiendo unasentamiento posterior de bajo momento de torsión mediante la rotación delvástago relativo al anillo de cojinete y tapa de sombrerete.
