Sprinkler and method for testing a sprinkler

摘要

A sprinkler head and a method for testing the sprinkler head, including an inlet device to lead fire-extinguishing medium and air from a distribution system into the sprinkler head, an outlet device to release fire-extinguishing medium and air from the sprinkler head, a flow passage to lead fire-extinguishing medium and air from the inlet device to the outlet device, a valve to be held in first non-activated state by a triggering device in the sprinkler head, so the flow passage is closed, and in activated state to open the flow passage, when the triggering device is activated in a heated state, so air and fire-extinguishing medium may flow from the inlet device to the outlet device. The valve in a second non-activated test state operatively opens the flow passage, so air and fire-extinguishing medium may flow from the inlet device through the flow passage and out through the outlet device.

主权项

1. A sprinkler head comprising
an inlet device configured to operatively lead a fire-extinguishing medium and air from a distribution system into the sprinkler head, an outlet device configured to operatively release fire-extinguishing medium and air from the sprinkler head, a flow passage configured to lead fire-extinguishing medium and air from the inlet device to the outlet device, a valve device configured to operatively be held in a first non-activated state by a triggering device in the sprinkler head, so that the flow passage is closed, and configured to in an activated state operatively open the flow passage when the triggering device is activated in a heated state, so that air and fire-extinguishing medium may flow from the inlet device to the outlet device,whereinthe valve device is configured to in a second non-activated test state operatively open the flow passage so that air and fire-extinguishing medium may flow from the inlet device through the flow passage and out through the outlet device, wherein the triggering device in the test state is maintained in an unchanged state and an unchanged position in relation to the inlet device and the outlet device,and wherein the function of the sprinkler head is maintained unchanged during the testing procedure.
