Embodiment
Below in conjunction with description of drawings, the utility model specific embodiment is described.
Like accompanying drawing 1,2,3, shown in 4, air door 1 back has flange arrangement and is installed on the air channel 22 through bolt.The bottom of air door 1 front has boss structure, and there is thermal insulation layer boss inside.On boss, be horizontally installed with rotating shaft 3, rotating shaft 3 two ends and air door 1 contacting point are provided with bearing 13, the convenient rotation.The left end of rotating shaft 3 is provided with gear 4, connects swing arm 12 in the middle of the rotating shaft.The other end of swing arm 12 is connected on the belt length hole otic placode 11 of air door plate 2 through pin 10.The cylinder 6 of band two-position-five-way solenoid valve 7 is fixed on the cylinder block 8 in air door 1 left side, and piston rod connects tooth bar 5, tooth bar 5 and gear 4 engagements.Be provided with spacing card 14 at tooth bar 5 away from cylinder one end, to prevent tooth bar 5 skews.Upper middle position in air door 1 front is provided with " U " shape draw-in groove 15, is provided with flexible block 21 in the bottom of air door 1.
Be provided with seal groove 23 in air door 1 and air door plate 2 contacting points, be provided with heat resistant joint ring 24 in the seal groove 23.
Working principle is following:
1. operation automatically
Two-position-five-way solenoid valve 7 is chain with blower, and when blower fault, solenoid valve obtains the electrical signal switching-over and opens, the inflation of cylinder 6 upper ends, and piston rod drives tooth bar and stretches for 5 times, and tooth bar 5 driven gears 4 counterclockwise rotate.Gear 4 drives rotating shaft 3 and the swing arm 12 choosing commentaries on classics counterclockwise of being fixed in the rotating shaft 3 again, and swing arm 12 promotes air door plates 2 and is rotated counterclockwise around minor axis 18.Because minor axis 18 and rotating shaft 3 decentraction, air door plate 2 is sold 10 and will in the slotted hole of belt length hole otic placode 11, be moved up and down in rotation process, to compensate the range deviation that decentraction causes.When air door plate 2 reaches horizontal position and the flexible block of air door 1 bottom 21 collisions and accomplish and open, flexible block plays bumper and absorbing shock effect and position-limiting action.
Close closed procedure and open fully on the contrary.
2. manually-operable
When automatic open function fault, wanting manually-operable, mainly is the manual-lock process.When closing air door, pull handle is closed air door plate 2, and pull-up is adsorbed on eye-nut 17 and ring-bolt 16 on the air door plate 2, makes it pass " U " shape draw-in groove 15 on the air door 1, and tightens eye-nut 17 with locking air door plate 2.Opening process is opposite with the pass closed procedure fully.
The above only is the preferred embodiments of the utility model, is not the utility model is done any pro forma restriction.
