Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention selectes embodiment.
1, external door gland, 2, explosion-proof template, 3, fastening piece, 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, hanging body, 11, inside door cylindrical shell, 12, relief hole, 13, high-temperature furnace body, 14, fore-set, 15, interior relief hole.
Embodiment
Better understand the present invention for the ease of those skilled in the art, be described in further details below in conjunction with the drawings and specific embodiments to the present invention, following is only exemplary do not limit protection scope of the present invention.
With reference to accompanying drawing 1, a kind of ultra-high-temperature furnace anti-explosion, comprises inside door and external door; Inside door comprises inside door cylindrical shell 11, inside door gland 8 and multiple extension spring 9, inside door cylindrical shell 11 is arranged on high-temperature furnace body 13, inside door gland 8 matches with inside door cylindrical shell 11, and extension spring 9 one end is arranged on inside door gland 8, and extension spring 9 the other end is arranged on high-temperature furnace body 13 by hanging body 10; 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, and external door cylindrical shell 7 with the outside being located in inside door cylindrical shell 11, and external door cylindrical shell 7 has relief hole 12, and external door gland 1 and external door cylindrical shell 7 removably connect and be integrated.
In the present embodiment, inside door gland 8 inwall is arranged on inside door cylindrical shell 11 outer wall top with cone match.
In the present embodiment, inside door gland 8 is provided with multiple fore-set 14, and fore-set 14 is highly less than the distance between external door gland 1 and inside door gland 8, adopts the distance that this structure can ensure 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 fastening piece 3, explosion-proof template 2 is installed.
In the present embodiment, external door cylindrical shell 7 upper end outer wall is fixed with external door connecting plate 6, is connected as one by bolt and nut component 4 between external door gland 1 and external door connecting plate 6.
In the present embodiment, between external door connecting plate 6 and external door gland 1, be provided with sealed bolster plate 5.
