Abstract

The utility model discloses a fire-extinguishing door which can automatically extinguish the fire. One side of a door body is hinged on door frame by hinges, and the door frame is provided with a cavity and the liquid inlets of the cavity. The door frame is fixedly provided with liquid spraying tubes which are communicated with the cavity of the door frame, and the cavity of the door frame is filled with fire extinguishing agents. The insides of the tubes of the front parts of the spray heads of the liquid spraying tubes and the liquid inlets of the cavity of the doorframe are respectively provided with temperature controlling valves of the normally closed type.

Description

Fire-extinguishing door

The utility model relates to a kind of door.

China's utility model patent discloses a kind of aerosol labeled door for No. 93238669.5, and this labeled door is provided with cavity at doorframe and door in the body, and is provided with the micropore with exterior at doorframe cavity and door body cavity top.When near the labeled door during breaking out of fire, can be by doorframe and door body cavity inflow port to a doorframe and the inner tap water that injects of door body, avoid doorframe and door body in fire because of too high damage of heating up.Above-mentioned labeled door can prevent effectively that fire from dropping in and spread that flameproof effect is remarkable.But it can not stamp out a fire on one's own initiative, thereby awaits further improving.

The purpose of this utility model provides a kind of Fire-extinguishing door that can initiatively stamp out a fire.

The door body that Fire-extinguishing door of the present utility model has doorframe and matches with doorframe, a side of door body is articulated on the doorframe by hinge.The inflow port that doorframe has cavity and communicates with this cavity.On doorframe, also be set with the sparge pipe that is connected with the doorframe cavity especially.In the doorframe cavity, be filled with extinguishing chemical.In the pipeline of sparge pipe shower nozzle front end, be provided with normally closed type temperature control valve respectively with doorframe cavity inflow port place.When using Fire-extinguishing door of the present utility model, can be in advance with doorframe cavity inflow port be connected with the high pressure tap water pipeline.Near in case the breaking out of fire Fire-extinguishing door, the normally closed type temperature-sensing valve goalkeeper that in the sparge pipe shower nozzle front-end pipelines and doorframe cavity inflow port place is provided with experiences high temperature and opens automatically, the high pressure tap water enters the doorframe cavity along with the unlatching of valve, the extinguishing chemical that orders about filling in the doorframe cavity is implemented fire-extinguishing function concurrently from the ejection of sparge pipe shower nozzle.After the extinguishing chemical dispensing of filling finished, the high pressure tap water continued from the shower nozzle ejection remaining kindling material to be put out.In the utility model, the normally closed type temperature control valve of setting can be commercially available existing electronic temperature control valve, also can adopt be fixed in the runner, with the meltable shutoff sheet of runner shutoff, to constitute easy normally closed type temperature control valve.The extinguishing chemical of filling in the doorframe cavity can be common extinguishing chemicals such as water glass.The sparge pipe that is provided with is changeable, and its shower nozzle also can be a plurality of.When long and shower nozzle is a plurality of when sparge pipe, can on the room ceiling, be bent to form the hydrojet pipe network, make it to have bigger fire-fighting area and stronger extinguishing ability.

Fire-extinguishing door of the present utility model is compared with aforementioned existing labeled door, and its fire resistance property is stronger, and has the advantages that initiatively to stamp out a fire.

Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Fig. 1 is the structural representation of Fire-extinguishing door among the embodiment.

Fig. 2 is a vertical view.

Shown in Fig. 1～2, the Fire-extinguishing door among the embodiment has doorframe 1 and panel door body 2, and a side of door body 2 is articulated on the doorframe 1 by hinge 3.Doorframe and door body have cavity 4,5 respectively, have metal between the cavity 4,5 and are communicated with flexible pipe 7.Doorframe is provided with inflow port 6 and the sparge pipe 8 that communicates with the doorframe cavity.In doorframe cavity 4, be filled with water glass solution 10 as extinguishing chemical.Be provided with micropore 12 with exterior at the top of door body cavity 5.In the front-end pipelines of the shower nozzle 9 of sparge pipe and inflow port 6, be communicated with in the flexible pipe 7 and be provided with meltable shutoff sheet 11, to constitute easy normally closed type temperature control valve.In the present embodiment, the purpose that cavity 5, micropore 12 and connection flexible pipe 7 are set on the door body is the security performance that further strengthens Fire-extinguishing door self, improves its back-fire relief ability.When using the Fire-extinguishing door of present embodiment, the high pressure tap water pipeline of inflow port 6 with the user can be joined, and sparge pipe is bent to form the hydrojet pipe network on the room ceiling.In case near the breaking out of fire Fire-extinguishing door, meltable shutoff sheet 11 will be subjected to high-temperature baking and melt, and the high pressure tap water enters doorframe cavity 4 from inflow port 6, order about the part water glass solution from shower nozzle 9 ejection fire extinguishings; Another part water glass solution access door body cavity 5, from micropore 12 ejections, the opposite house body self protects again.After water glass solution sprayed and finishes, the high pressure tap water continued from shower nozzle 9 and micropore 12 ejections remaining kindling material to be put out.
