Abstract

The invention relates to an overpressure sa-fety device (1) for pipeline networks, comprising an inlet pipe leading from the pipeline network to be secured to the overpressure safety device (1), at least one safety valve, and a discharge pipe. According to the invention, at least two safety valves (2, 3) are provided, and both safety val-ves comprise an inlet side and an outlet side, wherein the first safety valve (2) is connected to a pipe of the pipeline network, and the first is connected to the second safety val-ve (3) by a connecting pipeline (4). The connecting pipe (4) thereby has an inlet pipe and a discharge pipe, by means of which a liquid or gaseous purge, cleaning, and/or sterilization agent can be fed in and discharged.
