The specific embodiment
Describe particular content of the present utility model in detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 3, Fig. 4, shown in Figure 5, dismountable type flue fire-preventing check valve, comprise: shell 1, be arranged on the exhaust gases passes in the shell 1, rotate the valve block 3 that is arranged in the shell 1 by rotating shaft 2, rotating shaft 2 is positioned at position on the upper side, valve block 3 centers, is respectively arranged with the air inlet 4 and the air outlet 5 of mutual correspondence on the two ends that flue gas ventilates, valve block 3 is arranged near in the exhaust gases passes of air inlet 4 one sides, and described valve block 3 has two operating positions.As shown in Figure 3, an operating position is that valve block 3 is in the closed position, and at this moment, the oral area that valve block 3 covers at air inlet 4 is spaced from each other air inlet 4 and air outlet 5.As shown in Figure 4, another operating position is that valve block 3 is shown in an open position, and valve block 3 departed from air inlet 4 air inlet 4 and air outlet 5 were interconnected under the effect of flue gas this moment.As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, in described air outlet 5, be set with horizontal support plate 6, top board 7 rotates by bolt 8 and is arranged on the middle part of horizontal support plate 6, one end of top board 7 is connected with an end of fuse link 10 by connecting bolt 9, the other end of fuse link 10 is fixed on the end of horizontal support plate 6 by set bolt 11, on the other end of horizontal support plate 6, be set with spring 12, the other end of spring 12 is fixed on the connecting bolt 9, on described valve block 3, be set with baffle plate 13, when fuse link 10 disconnects, top board 7 can offset the other end of top board 7 and baffle plate 13 around bolt 8 rotations under the effect of spring 12, shifts valve block 3 onto closed position.
Above-mentioned dismountable type flue fire-preventing check valve is contained in when using on the flue, and as shown in Figure 4, when flue gas passed through gas flue, valve block 3 departed from air inlet 4 under the effect of flue gas, be in open mode.As shown in Figure 5, when fire occurring, a large amount of high temperature pernicious gases will pour in the gas flue, temperature in the gas flue is higher, and fuse link 10 is disconnected, and top board 7 rotates around bolt 8 under the effect of spring 12, the other end and the baffle plate 13 of top board 7 are offseted, shift valve block 3 onto closed position.Thereby the high temperature pernicious gas in the gas flue is cut off, prevent that it from entering into the user family that uses smoke exhaust ventilator by gas flue, guarantee user's life security.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the utility model spirit and protection domain; can also make various variations and modification, so all technical schemes that are equal to also should belong to protection category of the present utility model.
