Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a sprinkler nozzle. Background Art

[0002] There are four types of sprinkler heads, namely pendent sprinkler heads, upright sprinkler heads, ordinary new sprinkler heads, and sidewall sprinkler heads. Sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed through the sprinkler head splash plate to extinguish the fire. Fire sprinkler heads have been widely used. Fire sprinkler heads are considered to be the most effective way to extinguish fires. They can control the spread of fires in time and ensure the safety of life and property. In addition to specially designed systems, when a fire sprinkler head puts out a fire, the entire sprinkler fire extinguishing system will be activated.

[0003] The sprinkler nozzle is activated automatically within a predetermined temperature range under the action of heat, or is activated by a control device according to a fire signal, and sprays water according to the designed sprinkler shape and flow rate. The sprinkler system also has some defects and problems. Debris in the water tank or pool enters the pipe, which will cause the sprinkler head to be blocked for a long time, and the glass tube takes a long time to sense the heat. When the fire source is far away, the glass tube cannot sense the heat quickly, which results in the sprinkler head being unable to spray and extinguish the fire in the first time, greatly affecting the working efficiency of the sprinkler nozzle.

[0004] Therefore, a shower nozzle is proposed. Utility Model Content
