The invention relates to a method for producing a flange blank (), comprising the following step: producing a base body (), wherein the base body () comprises a fluid passage (), a support section () having a first material thickness (M) and a force-absorbing section () having a second material thickness (M), the second material thickness (M) is greater than the first material thickness (M), and the force-absorbing section () is configured for the selective production of through-holes (--) according to a first drilling pattern and/or a second drilling pattern. The invention further relates to a method for producing a flange (). In addition, the invention relates to a flange blank ().

Method for producing a flange blank and for producing a flange

The invention relates to an alarm valve station (), in particular a wet alarm valve station, of a fire extinguishing system (), having an alarm valve () with an extinguishing fluid inlet () and an extinguishing fluid outlet (), wherein the alarm valve () has a closing body that can be moved back and forth between a blocking state and a release state, wherein the fluid inlet chamber and the fluid outlet chamber are separated from one another in the blocking state and communicate with one another fluidically in the release state, an alarm triggering device () for triggering a fire alarm, which is connected with the alarm valve (), and a delay container () in order to delay triggering of the fire alarm, wherein the alarm valve () is fluidically connected with a fluid inlet () of the delay container, and a fluid outlet (-) of the delay container () is fluidically connected with the alarm triggering device (). The invention proposes that the delay container () have several fluid inlets () and/or several fluid outlets (-).

Alarm valve station of a fire extinguishing system, and fire extinguishing system

A fire extinguishing system valve () comprising a housing () which has a fluid inlet chamber (), a fluid outlet chamber () and a closing body () reciprocable between a blocking state and a release state, wherein the fluid inlet chamber () and the fluid outlet chamber () are separated from each other in the blocking state and communicate with each other in fluid-conducting relationship in the release state. At least one pressure sensor () is integrated in the housing ().
