Detailed Description
An easy-open vertical door fireproof check valve comprises a support plate 11 arranged in a check valve frame body 5, wherein the middle of the support plate 11 is provided with an oil fume exhaust hole 11-1 with two through sides, the oil fume exhaust hole 11-1 extends outwards to the same height as one hole wall 11-2, the same side of the support plate 11 with the hole wall 11-2 is rotatably provided with a cover plate 9 for sealing the oil fume exhaust hole 11-1 through a first rotating shaft 13, the first rotating shaft 13 is arranged along the vertical direction, the same side of the support plate 11 with the cover plate 9 is provided with a baffle support plate 8 and a fuse support plate 7 which are vertically arranged with the support plate 11, the baffle support plate 8 is provided with a baffle 2 for blocking the opening of the cover plate 9 through a second rotating shaft 1, the second rotating shaft 1 is sleeved with a second torsion spring 3 for bouncing the baffle 2 open, the end of the fuse support plate 7 is fixedly provided with a fusing hook 4 for locking the baffle 2, the melting point of the fusing hook 4 is not more than 150 ℃.
The utility model discloses install in the wind channel of chimney, first pivot 13 has realized the vertical structure of opening the door of apron 9 along vertical direction installation setting, compares the structure of opening the door from top to bottom in the past, and apron 9 can not shelter from the oil smoke. Normally, as shown in fig. 2, the shutter 2 is locked by the fusing hook 4 and does not block the opening of the cover plate 9. The oil fume flow blows the cover plate 9 outwards by the wind power generated by the fan of the range hood, and then the oil fume exhaust hole 11-1 can be opened, so that the oil fume exhaust is realized.
