METODO Y APARATO PARA EFECTUAR UNA ESTANQUIDAD DE PRESION ENUN VAPORIZADOR DE ALTA PRESION PARA EL TRATAMIENTO DE PRO- DUCTOS FIBROSOS.

摘要

A method of forming a pressure seal by employing an air balance in a high pressure steamer in which pressurized sealing gas is introduced into an air seal chamber which is shut off from the outside air by a roll seal mechanism installed at the fiber feed in and take out openings of a high pressure steamer vessel body, so that the sealing gas and steam leaking from within the vessel body into the air seal chamber buffer each other for forming and air balance within the vessel body.
