OVERPRESSURE PROTECTION MEANS

The invention relates to an overpressure protection means (1) comprising a housing (2), at least one outlet opening (3) formed in the housing (2), at least one rupture disc (4) arranged on the housing (2) in front of the outlet opening (3), and at least one housing connection (5) formed on the housing (2) for connecting the overpressure protection means (1) to a pressurised volume to be protected by the overpressure protection means (1), wherein the overpressure protection means (1) is designed in such a way that the housing connection (5) is connected to the outlet opening (3) in the housing (2) in a protection situation, such that the pressure in the volume is applied to the rupture disc (4) arranged in front of the outlet opening (3). The object of the invention is to provide an improved overpressure protection means, which offers a simple, integrated option for safely separating the connection between the housing connection and the outlet opening, for the exchange of the rupture disc, in order to be able to prevent a complete discharge of the pressure in the volume. According to the invention, a stop valve (6) integrated between the housing connection (5) and the outlet opening (3) is provided in the housing (2), which enables a separation of the connection between the housing connection (5) and the outlet opening (3) for a maintenance situation, in particular for the exchange of the rupture disc (4).
