Abstract
The invention relates to an overpressure safety 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 valves 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 valve (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.
Claims12
A pressure relief device for pipeline networks, said pressure relief device comprising:
- a supply line, which leads from a pipeline network to be made safe to the pressure relief device, and in addition has at least one safety valve and one discharge line,
- at least two safety valves, the at least two safety valves including
- a first safety valve having an inlet side and an outlet side, the first safety valve being connected to a line of the pipeline network;
- and
- a second safety valve having an inlet side and an outlet side, the second safety valve being connected to the first safety valve via a connecting pipeline,
- wherein the connecting pipeline has a supply line and a discharge line, by means of which a liquid or gaseous flushing, cleaning and/or sterilizing agent can be supplied or removed.
A method for pressure relief in pipeline networks, said method comprising:
- providing a pressure relief device comprising a supply line, which leads from the pipeline network to be made safe to the pressure relief device, the supply line having at least one safety valve and one discharge line, at least two safety valves, the at least two safety valves including a first safety valve having an inlet side and an outlet side, the first safety valve being connected to a line of the pipeline network;
- a second safety valve having an inlet side and an outlet side, the second safety valve being connected to the first safety valve via a connecting pipeline, wherein the connecting pipeline has a supply line and a discharge line, by means of which a liquid or gaseous flushing, cleaning and/or sterilizing agent can be supplied or removed.
