Device for triggering a fire extinguishing system by means of a sprinkler

摘要

A device is provided for triggering a fire extinguishing system by a sprinkler, the device being arranged between the pipe for the extinguishing agent and the sprinkler and including a multiple-armed toggle-lever joint acting between a load axis of the triggering element and a sealing element that is arranged at an angle of 80 to 120° thereto. The device has the advantage that dry pipe sprinklers whose glass bulbs can only absorb low mechanical forces can also be arranged for use with pipes that exhibit large entry cross-sections, large volume flows and high pressures as the forces from the pipe that arise have to be absorbed only in part by the sprinkler glass bulb. It is further advantageous that the sealing force of the sealing element can be adjusted by means of an actuator.

主权项

1. A device for triggering a fire extinguishing system comprising:
a sprinkler having a passageway therethrough and a heat responsive triggering element supporting a closure within the passageway, a body adapted to be arranged between a pipe for an extinguishing agent and the sprinkler, and a multiple-armed toggle-lever joint (6) disposed within the body that acts between a load axis (19) of the triggering element of the sprinkler and a sealing element that is arranged at an angle of 80 to 120° relative to the load axis, wherein the multi-armed toggle-lever joint (6) includes at least four arms and at least four articulated connections (6.2) that connect respective ends of the at least four arms, the articulated connections being configured as single-point connections that act in the middle against their respective supports and wherein the sealing element, which closes off the pipe for the extinguishing agent in a gas-tight manner, is configured as a valve plate (8) against which the multi-armed toggle-lever joint (6) acts.
