Description
[technical field]
The utility model relates to the technical field of fire retardant device, particularly a kind of technical field of novel fire-retardant core.
[background technology]
Fire-retardant core is made up of many thin channel or hole, after flame enters these thin channel, just forms many tiny flame flow.Because the heat transfer area of passage is large, after flame carries out heat exchange by conduit wall, temperature declines, and the flame that acquires a certain degree can extinguish.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of novel fire-retardant core is proposed, by installing an outer rim outside back-fire relief net cylinder, fire-retardant core and inner-walls of duct can be made better to fit tightly, sealing back-fire relief is effective, and between back-fire relief net cylinder and outer rim, install multiple wall stream circle additional, the intensity of a fire can better import in back-fire relief net cylinder by the diversion section on wall stream circle simultaneously, can be good at suppressing flame transmission, extinguishing effect is good.
For achieving the above object, the utility model proposes a kind of novel fire-retardant core, comprise central axle sleeve, corrugated plating, outer rim and some wall stream circles, described corrugated plating winding forms back-fire relief net cylinder, back-fire relief net cylinder is installed on central axle sleeve, back-fire relief net cylinder is provided with somely leads fiery through hole, outer rim is installed on outside back-fire relief net cylinder, described wall stream circle is installed between outer rim and back-fire relief net cylinder, described wall stream circle is successively by inserting paragraph, linkage section and diversion section are formed, described inserting paragraph, linkage section and diversion section are structure as a whole, inserting paragraph is the first downward-sloping ramp structure, diversion section is acclivitous second ramp structure, between described outer rim and central axle sleeve, some levers are installed.
As preferably, described in lead fiery through hole cross section be polygonized structure, the limit number of polygonized structure is 3 ~ 6.
As preferably, described lever one end is connected with outer rim, and the other end of lever is connected with central axle sleeve, and the quantity of described lever is 2 ~ 6, and lever circular array is distributed in the upper surface of back-fire relief net cylinder.
As preferably, described wall stream circle is installed on the rear side of back-fire relief net cylinder, and inserting paragraph is inserted between outer rim and back-fire relief net cylinder.
As preferably, the angle of inclination of described inserting paragraph is 5 ~ 15 °, and the angle of inclination of diversion section is 10 ~ 20 °, and described diversion section is provided with 3 ~ 5 guide vanes.
The beneficial effects of the utility model: the utility model by installing an outer rim outside back-fire relief net cylinder, fire-retardant core and inner-walls of duct can be made better to fit tightly, sealing back-fire relief is effective, between back-fire relief net cylinder and outer rim, install multiple wall stream circle additional simultaneously, the intensity of a fire can better import in back-fire relief net cylinder by the diversion section on wall stream circle, can be good at suppressing flame transmission, extinguishing effect is good.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
