Description

A fire sprinkler head mounted on the side of the alarm component

Technical field

The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting sprinkler head mounted on the side of an alarm component.

Background technique

The alarm function of traditional fire sprinklers is accomplished through water flow alarms or water flow indicators in fire pipes. The cost of water flow alarms and water flow indicators is relatively high, and the water flow alarms or water flow indicators need to be installed in the main pipe. This is more troublesome to install. If the water flow alarm or water flow indicator is installed at the main pipe position, it will not be possible to tell which sprinkler head in the fire protection system is operating during use, which will cause a delay in locating the fire. In addition, in some places, due to historical or cost reasons, fire sprinklers are not installed on independent fire pipes, but are installed on domestic water pipes. It is impossible to install traditional water flow alarms or water flow indicators on domestic water pipes. So that when a fire danger occurs, there will be no alarm action at all when the fire sprinkler nozzles operate, causing delays in fire fighting; in addition, because water spray will cause certain property damage, and generally if there is no manual closing of the valve, the water spray will continue Continuously, if there is no alarm action, there is no way to control the loss of water spray.

Technical solutions

The object of the present invention is to provide a fire sprinkler head with an alarm component mounted on the side.

The heat-sensitive deformation element 10 in this embodiment is a bimetallic piece. When used, the temperature at which the heat-sensitive deformation element 10 deforms when exposed to heat is lower than the temperature at which the induction activation element ruptures when exposed to heat. This allows the thermal deformation element 10 to be deformed when a fire hazard occurs. Before the induction start-up part breaks, the cantilever end of the thermal deformation part 10 will deform and press the trigger pin 91 of the early warning switch 9, so that the main control MCU module gets the signal from the early warning switch 9 to control the buzzer to make a sound.
