High-pressure water mist fire extinguishing system

Abstract

The invention discloses a high-pressure water mist fire extinguishing system. The system comprises a fixed flange and a spray head; the top of the spray head is communicated with a hard pipe; a waterseparation tank is fixedly connected in the hard pipe; a first electric expansion link is fixedly connected in the water separation tank; the bottom end of the first electric expansion link is fixedlyconnected with a pull rod; and the bottom end of the pull rod is fixedly connected with a conical block. The high-pressure water mist fire extinguishing system relates to the technical field of fireextinguishing devices. According to the high-pressure water mist fire extinguishing system, the first electric expansion link is matched with the pull rod, so that the conical block can be pulled to lift; through controlling the distance between the conical block and the bottom of the spray head, the range of mist sprayed by the spray head can be controlled, if the range is enlarged, the mist is relatively dispersed, if the range is relatively small, the mist is relatively concentrated, so that different scales of fire behaviors can be adapted and water can be saved; and by utilizing matchingbetween a support rod and a support sleeve, the pull rod does not waggle severely when the conical block is impacted by high-speed mist, and then the mist spray stability is kept.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing devices, in particular to a high-pressure water mist fire extinguishing system. Background technique [0002] Fire refers to the disaster caused by burning out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. Human beings can use and control fire, which is an important symbol of civilization progress. Therefore, the history of human use of fire and the history of fighting against fire go hand in hand. While using fire, people constantly summarize the law of fire occurrence and minimize fire and its harm to human beings. In the event of a fire, it is necessary to escape safely and as soon as possible. Household fires are generally caused by people's negligence, and often happen suddenly, making people caught off guard, and the consequences are very serious. [0003]...
