Abstract (en)

[origin: WO2023285506A1] The invention relates to a slide gate valve (10) for chemical and/or petrochemical industrial plants, comprising: - a valve housing (11), which comprises an inlet port (12) having an exit opening (13) and an outlet port (14) having an entry opening (15), which correspond with each other when the slide gate valve (10) is in an open position; - a blocking device (16) having at least one blocking plate (17) and having a pipe bridge (18), which is movably disposed between the inlet and outlet ports (12, 14) for the opening and closing of the slide gate valve (10); and - at least one guiding device (19) for guiding flow, the guiding device (19) having at least one guiding element (21), which is located on an inner wall (22) of the inlet port (12) and reduces the exit opening (13) of the inlet port (12) such that, as the slide gate valve (10) is being opened, an opening cross-section (23) of the exit opening (13) is enlarged at the moment of an initial, in particular first, flow ingress into the pipe bridge (18).
