Problems solved by technology

[0002] The alarm function of the traditional fire sprinkler is completed by the water flow alarm or water flow indicator in the fire pipeline. The cost of the water flow alarm and water flow indicator is relatively high, and the water flow alarm or water flow indicator needs to be installed at the main pipe position. This is more troublesome to install. Install the water flow alarm or water flow indicator to the main pipe, so that it is not clear which sprinkler in the fire protection system is operating when in use, resulting in delays in fire location.
In addition, in some places now, due to hist

Abstract

The invention relates to a fire sprinkler with an alarm function, which comprises a sprinkler body and an alarm, the sprinkler body is provided with a water outlet, and the sprinkler body is provided with an induction valve body for blocking the water outlet. The alarm comprises a shell, a water retaining deflector rod, an alarm switch and an alarm circuit; wherein the shell comprises a lower cover and an upper shell, and the upper shell is connected to the bottom of the nozzle body; the lower cover and the upper shell are connected to form a cavity, the bottom surface of the lower cover is an arc-shaped convex surface, and a circular bulge is formed in the center of the bottom surface of the lower cover; a water retaining end and a pressing end are arranged on the water retaining deflector rod, the water retaining end is arranged close to the water outlet, and the water retaining deflector rod is rotatably mounted on the shell. The alarm circuit is arranged in the cavity of the shell; the alarm switch is installed on the shell and used for controlling starting of the alarm circuit, and the action triggering end of the alarm switch makes contact with the pressing end. The fire sprinkler has the advantages of being convenient to construct, maintain and use, capable of easily improving an existing fire sprinkler and the like.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting nozzle with an alarm function. Background technique [0002] The alarm function of the traditional fire sprinkler is completed by the water flow alarm or water flow indicator in the fire pipeline. The cost of the water flow alarm and water flow indicator is relatively high, and the water flow alarm or water flow indicator needs to be installed at the main pipe position. It is cumbersome to install like this, and the water flow alarm or the water flow indicator is installed at the main pipe position, so that it is not clear which sprinkler in the fire protection system is operating when in use, so that the time delay of fire location is caused. In addition, in some places now, due to historical or cost reasons, fire sprinklers are not installed on independent fire pipelines, but on domestic water pipelines. It is impossible to install traditional wa...
