Accompanying drawing explanation
Fig. 1 is the structural representation of the selected embodiment of the utility model.
1, external door gland, 2, explosion-proof template, 3, securing member, 4, bolt and nut component, 5, sealed bolster plate, 6, external door connecting plate, 7, external door cylindrical shell, 8, inside door gland, 9, extension spring, 10,, 11, inside door cylindrical shell, 12, relief hole, 13, high-temperature furnace body, 14, fore-set, 15, interior relief hole.
The specific embodiment
Better understand the utility model for the ease of those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further details, following is only the exemplary protection domain of the present utility model that do not limit.
With reference to accompanying drawing 1, a kind of superhigh temperature body of heater explosion proof door, comprises inside door and external door; Inside door comprises inside door cylindrical shell 11, inside door gland 8 and two extension springs 9, and inside door cylindrical shell 11 is arranged on high-temperature furnace body 13, and inside door gland 8 matches with inside door cylindrical shell 11, and extension spring 9 one end are arranged on inside door gland 1, and extension spring 9 other ends are arranged on high-temperature furnace body 13; External door comprises external door cylindrical shell 7 and external door gland 1, and external door cylindrical shell 7 is arranged on high-temperature furnace body 13, the same outside that is located in inside door cylindrical shell 11 of external door cylindrical shell 7, and on external door cylindrical shell 7, have relief hole 12, external door gland 1 and external door cylindrical shell 7 removably connect and are integrated.
In the present embodiment, inside door gland 8 inwalls are arranged on inside door cylindrical shell 11 outer wall tops with cone match.
In the present embodiment, inside door gland 8 is provided with two fore-sets 14, and fore-set 14 is highly less than the distance between external door gland 1 and inside door gland 8, adopts this structure can guarantee the distance between external door gland 1 and inside door gland 8, to reach quick pressure releasing, explosion-proof object.
In the present embodiment, between external door gland 1 and external door cylindrical shell 7, through securing member 3, explosion-proof template 2 is installed.
In the present embodiment, on external door cylindrical shell 7 upper end outer walls, be fixed with external door connecting plate 6, between external door gland 1 and external door connecting plate 6, connect as one by bolt and nut component 4.
In the present embodiment, between external door connecting plate 6 and external door gland 1, be provided with sealed bolster plate 5.
