摘要

Screen of angled tubes (1) for treatment of aseptic product, with a shell body (2) extended in the form of a cup, which is detachably closed with a housing lid (6), with a sieve insert (5 ) extended in the form of a tube that is oriented with its longitudinal axis at least parallel to the longitudinal axis of the body of the housing (2) therein, and which is interchangeably housed, on the one hand, on a floor of the housing (2b) of the housing body (2) and on the other hand in the housing cover (6), in which between a perforated drum (5a) of the sieve insert (5) and a housing envelope ( 2a) of the housing body (2) an annular space (11) is formed with an inlet support (2d) arranged on the floor of the housing with an inlet opening (2e), which establishes a continuous joint for fluids towards the inner space of the perforated drum (5a), with an outlet support (2f) disposed in the housing envelope (2a) with n an outlet opening (2g) that establishes a continuous connection for fluids to the annular space (11) with at least one passage opening (5e) formed in the region of the housing cover (6) in the sieve insert (5), optionally connectable, through which the inner space of the perforated drum (5a) is optionally connected with the annular space (11), in which the passage opening (5e) is surrounded by a seat ring ( 5d) that surrounds the perforated drum (5a) on the front, in which, or in the passage opening (5e), a first seating surface (5f) is formed, in which the passage opening (5e), through a closing element (4a) that travels by translation, which acts together with a second seating surface (4c) with the first seating surface (5f) optionally opens or closes, being joined the closing element (4a) through the valve rod (4e) passed through the cover of the housing (6) with a drive (3) that can be operated remotely, and this step being bridged with a bellows (4) that coaxially surrounds the valve rod (4e) and which, on the one hand, is connected with the closing element (4a), and on the other hand with the housing cover (6).
