Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1-Fig. 5, the utility model is an exhaust gas flue pressure swing type oil extraction flue gas fire-preventing check valve between a kind of novel Kitchen hygiene, change over the straight-tube structure, this safety check is made for the integrated type metallic material, it comprises valve body 20, valve body 20 comprises suction port 21 and inserts the interior relief opening 23 of exhaust gas flue, valve body 20 also comprises a transformation case 24 that vertically is provided with, this transformation case 24 upwards extends in exhaust gas flue 10, relief opening 23 is arranged on the top of transformation case 24, but suction port 21 places are provided with the blade 22 of open and close.The setting of transformation case 24 makes relief opening 23 places form negative pressuren zone, has improved the flue gas flow rate in the gas flue.
Embodiment one, a kind of exhaust gas flue pressure swing type oil extraction flue gas fire-preventing check valve, comprise valve body 20, valve body 20 comprises the relief opening 23 in suction port 21 and the insertion exhaust gas flue 10, valve body 20 also comprises a transformation case 24 that vertically is provided with, this transformation case 24 upwards extends in exhaust gas flue 10, and relief opening 23 is arranged on the top of transformation case 23, but suction port 21 places are provided with the blade 22 of open and close.Not in safety check during smoke exhaust, blade 22 seals suction port 21 under action of gravity.In order to reach smoke exhaust effect preferably and to prevent that flue gas in the exhaust gas flue 10 is to indoor refluence, described blade 22 is installed in suction port 21 places by rotating shaft 213, rotating shaft 213 is connected with upper half part of blade 22, can make blade 22 lower half portion openings big and reach better smoke exhaust effect.Be respectively equipped with outstanding last blend stop 211 and following blend stop 212 on suction port 21 inwalls of rotating shaft 213 above and belows, upper and lower blend stop 211,212 is circular arc, and the arc length of following blend stop 212 is greater than the arc length of last blend stop 211.The blade of rotating shaft 213 tops is arranged on blend stop 211 outsides, and the blade of rotating shaft 213 belows is arranged on down in the blend stop 212.Like this, to suction port 21 smoke exhaust the time, can turn an angle, rotating shaft 213 is turned in valve body with the blade 22 of bottom at the effect lower blade 22 of blast, rotating shaft 213 with the blade 22 on top to turning up, thereby reach smoke exhaust effect preferably; And down the setting of blend stop 212 makes the flue gases that come in the exhaust gas flue 10 can not back down blade 22, has prevented that effectively flue gas in the exhaust gas flue 10 is to indoor refluence.
In addition, cigarette when preventing fire in the public exhaust gas flue 10, gas are in the relief opening inlet chamber, play anti-fire action simultaneously, also be provided with the blade hold down gag that can make blade 22 sealing suction ports 21, prevent the flue gas crossfire in the described valve body 20, described hold down gag is by the closure of coupled temperature sense fus 27 control blades 22.
In order to make blade 22 can better seal suction port 21, described blade hold down gag comprises that the depression bar that is installed on transformation case 24 inwalls ends lock 25, be inserted into the depression bar 26 that ends in the lock 25, end on the lock 25 and have axis hole 251, axis hole 251 belows have the only locked groove 252 that communicates with axis hole 251, depression bar 26 is provided with the chip rotating shaft 261 that can rotate in ending lock 25, ending locked groove 252 is horn mouth formula wide at the top and narrow at the bottom, ends in the locked groove 252 thereby depression bar 26 can successfully be slipped into.Chip rotating shaft 261 slips into when ending in the locked groove 252, and the lower end of depression bar 26 compresses blade 22, makes blade 22 be adjacent to upper and lower blend stop 211,212 and sealing suction port 21.
Thereby in order to make the chip rotating shaft 261 on the depression bar 26 can slip into the only locked groove 252 interior blades 22 that compress automatically, described depression bar 26 upper ends are provided with counterweight 262 and lower draw-bar 263, transformation case 24 internal upper parts are provided with hook 241, and temperature sense fus 27 two ends are hung on hook 241 and the lower draw-bar 263.
During use, when temperature sense fus 27 two ends are hung on hook 241 and the lower draw-bar 263 when not disconnecting, depression bar 26 is in plumbness, not to suction port 21 smoke exhaust the time, blade 22 seals suction port 21 under action of gravity, when to suction port 21 smoke exhaust, make flue gas flow into suction port 21 in effect lower blade 22 rotating certain angle of blast.When the oil smoke gas that flows into suction port 21 reaches certain temperature, or the oil smoke gas in the air outlet flue 10 are when reaching certain temperature, the 27 meeting automatic disconnections of temperature sense fus, depression bar 26 rotating certain angle and moving down under the effect of counterweight 262, chip rotating shaft 261 on the depression bar 26 enters depression bar and ends ending in the locked groove 252 of lock 25, make the lower end of depression bar 26 compress blade 22 sealing suction ports 21, can not rotate after depression bar 26 ends lock, thereby the crossfire that cuts off flue gas reaches the frpf effect.
When fire need re-use later, only depression bar 26 need be moved up made the chip rotating shaft 262 on the depression bar 26 shift out the only locked groove 252 that depression bar ends lock 25, new temperature sense fus 27 was installed on hook 241 and the lower draw-bar 263 get final product.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
