Definitions
- the invention relates to an overpressure safety device (1) for pipeline networks, which comprises a supply line which leads from the pipeline network to be secured to the overpressure safety device (1), has at least one safety valve and one discharge line.
- a supply line which leads from the pipeline network to be secured to the overpressure safety device (1)
- at least two safety valves (2) (3) are provided, and both safety valves have an inlet side and an outlet side, wherein the first safety valve (2) is connected to a line of the pipeline network, and the first with the second safety valve ( 3) is connected via a connecting pipe (4).
- the connecting line (4) has a supply line and a discharge line, via which a liquid or gaseous rinsing, cleaning and / or sterilizing agent can be supplied and discharged.
- an overpressure safety device (1) for pipeline networks which comprises a supply line which leads from the pipeline network to be secured to the overpressure safety device (1), at least one safety valve and one discharge line.
- the connecting pipe (4) has a supply line and a discharge line, via which a liquid or gaseous rinsing, cleaning and / or sterilizing agent can be supplied and discharged.
- the first safety valve (2) is constructed or adjusted such that it withstands a higher limit pressure than the safety valve (3).
- This design allows the opening of the first safety valve not to lead to sterility, but the process must not be interrupted following a pressure shock or a pressure peak.
- the pipe interior of the connecting pipe can be acted upon after such an event and regularly with a suitable sterilizing agent, such as steam, ozone, H 2 O 2 or peracetic acid.
- limiting pressure is meant here the pressure level at which the respective safety valve opens.
- the load capacity of the safety valves is such that the limit pressure of the second safety valve (3) is 50% below the limit pressure of the first safety valve (2) or even smaller.
- the pressure of the sterilizing medium, which is passed through the connecting pipe is below the limit pressure of the second safety valve.
- the flow guide in the connecting pipe (4) can be problematic especially when using liquid sterilizing agents, so that leads in an improved variant, the supply of sterilizing agent directly into the outlet side of the first safety valve (2) and the derivative directly with the inlet side of the second safety valve (3) is connected. This ensures that a defined flow in the connecting pipe (4) takes place.
- This variant can be further improved by the end of the supply line in the outlet side or in the connecting pipe is oriented such that its outlet is directed to the valve seat of the first safety valve (2). This ensures the fastest possible and highly effective sterilization of the valve seat.
- the end of the supply line should be a maximum of 20 mm away from the valve seat of the first safety valve (2).
- the invention further comprises a method for overpressure protection of piping networks, which comprises an embodiment of the aforementioned devices.
- FIG. 2 also shows schematically the overpressure protection device 1, which is particularly suitable for the use of a liquid sterilization medium.
- the supply line 7 branches in the connecting pipe into a left and a right branch.
- the right branch leads into the outlet side 12 of the first safety valve 2 and the outlet 13 of the right branch of the supply line 7 is directed directly onto the valve seat 14.
- the left branch of the supply line 7 leads into the inlet side 15 of the second safety valve 3 and the outlet 16 is the valve seat 17 directly opposite and is directed to this.
- an extension is provided so that residual liquid or condensate can collect and drain there.
- the discharge line 10 is also arranged. This arrangement certainly an ideal Stromungssselung in the connecting pipe. 4
