| 发明名称 | Safety fitting for blocking a line | ||
| 摘要 | 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. | ||

| 主权项 | 1. A Safety fitting for blocking a line, comprising: a housing having a widened section and a cylindrical closing section; and a blocking body, having a cylindrical section defining a maximal diameter of the blocking body, said blocking body being held in an open position in the widened section of the housing, and being guidedly and linearly displaceable in the line in a direction of flow of the line into a closed position, actively or in response to a pressure fluctuation, wherein in the closed position, the cylindrical section of the blocking body engages in the cylindrical section of the housing, thereby forming a cylindrical annular gap between the cylindrical section of the housing and the maximal diameter of the blocking body. | ||
