Abstract:
A safety fitting for blocking a line, includes a blocking body that is located in a widened section of a housing, can be guided linearly in the direction of flow of the line and is held in an open position. The blocking body can be moved under the influence of a pressure fluctuation in the line or moved actively into a sealing position. The housing has a cylindrical sealing section, in which the blocking body engages with a cylindrical section thereby forming a cylindrical annular gap.
