Fluid supply interface with safety valve for a cell culture plant, use of such a fluid supply interface for the management of cell culture containers and cell culture management plant

摘要

A fluid supply interface (10) comprises: - at least one supply coupling formation (20, 22, 24, 26, 28), - at least one disposal coupling formation (82, 84), - at least one consumer coupling formation (104), and - a fluid channel (16), a supply valve (64, 66, 68, 70, 72) through which, depending on its position, the supply coupling formation (20, 22, 24, 26, 28) is connected to each other, the supply, the disposal and the consumer coupling formation (104); ) can be flowed through by fluid or is blocked for a flow, - a disposal valve (94, 96) through which the Entsorgungskopplungsformation (82, 84) is traversed by fluid depending on its position or blocked for flow through, wherein the supply valve (64 , 66, 68, 70, 72) is biased in a flow-preventing blocking position and by sufficiently high pressure difference between the two sides of Versorgu ngsventils (64, 66, 68, 70, 72) opens against the biasing force for flow in the direction of the supply coupling formation (20, 22, 24, 26, 28) to the fluid passage (16) out, and wherein the disposal valve (94, 96) is also biased in a closed position preventing its flow. According to the invention, a disposal valve (94, 96) is designed as a safety valve (96), when a predetermined pressure difference between the two sides of the safety valve (96) is exceeded, against its biasing force to flow in the direction of the fluid channel (16) and to the disposal coupling formation (82 , 84) open.
