Pressure release device

A pressure relief device for a housing comprising:

• a wall connecting piece including an insertion connecting piece configured to be at least partially inserted into a housing opening of a housing wall of the housing and configured to be detachably fixed to the housing, the wall connecting piece including a support flange projecting radially outward from the insertion connecting piece and configured to rest on the outside of an opening edge of the housing opening when the insertion connecting piece is inserted and fixed to the housing, the wall connecting piece including a projecting connecting piece section opposite the insertion connecting piece section relative to the support flange, the projecting connecting piece section defining at least a portion of a longitudinal conduit running through the wall connecting piece;
• a flame-blocking body replaceably inserted into the longitudinal conduit;
• a pressure nut including a pressure edge projecting radially inward;
• an intermediate connecting piece configured to be arranged between the pressure nut and the wall connecting piece, the intermediate connecting piece including a connection piece end section configured to be threadably connected to the projecting connection piece section and a nut end section configured to be threadably connected to the pressure nut, wherein the intermediate connecting piece includes a pressure step which projects radially inward and loads the flame blocking body with pressure in the direction of the support step;
• and
• a sprayed water body loaded with pressure by the pressure edge of the pressure nut, the pressure edge configured to contact an outer viewing side of the sprayed water body, wherein the sprayed water body for protection against sprayed water has a higher density than the flame blocking body.

• a flame-blocking body replaceably inserted into the longitudinal conduit;
• a pressure nut including a pressure edge projecting radially inward;
• an intermediate connecting piece configured to be arranged between the pressure nut and the wall connecting piece, the intermediate connecting piece including a connection piece end section configured to be threadably connected to the projecting connection piece section and a nut end section configured to be threadably connected to the pressure nut, wherein the intermediate connecting piece includes a pressure step which projects radially inward and loads the flame blocking body with pressure in the direction of the support step;
• and
• a sprayed water body loaded with pressure by the pressure edge of the pressure nut, the pressure edge configured to contact an outer viewing side of the sprayed water body, wherein the sprayed water body for protection against sprayed water and the flame blocking body are elastic under pressure and include a pore closure on an outer edge side.
