For installing the rectangular opening of pressure balance air door, it is vertically equipped with middle shaft in the rectangular opening, the two of the pressure balance air door
Fan door is movably connected in middle shaft, and the side of the wherein Yishanmen lower end of pressure balance air door is equipped with baffle, another Yishanmen
Opposite side is equipped with baffle, and the rotation that pressure balance air door often fans door is made to open scope limitation between 0-90 °.
Preferably, the doorframe is the rectangle framework that is welded of 10# channel steels, the big balance air door by shaft
The both sides of doorframe are fixed on, doorframe is firm, will not deform.
Preferably, the big balance air door is made of thickness of the steel plate of 3mm, will not damage deformation.
Preferably, there are two the fixed pulley is set, point-blank, one of them is fixed in plate upper side edge for setting
The top of heart position, steel wire rope bypass described two fixed pulleys, easily adjust the length of steel wire rope.
Preferably, the rope-winding wheel is arranged on the underface of fixed pulley, and handle is provided on rope-winding wheel, easily rotates wiring
Wheel carries out folding and unfolding to steel wire rope.
Preferably, the centre position of the doorframe upper side frame is equipped with baffle, same when can close big balance air door
In a plane, prevent from misplacing.
Preferably, sealing strip is equipped at the big balance air door crack between a door and its frame, by active force and the door automatic paste tightening of negative pressure, is played
Sealing function avoids air door from leaking out.
The mining balance air door of the utility model, the regulation wind window on big balance air door door leaf, and the company of slip on air regulator
Plugboard, plate can be moved up and down according to practical adjustments in slideway, adjust ventilation quantity, during door opening, be utilized parallel double
Crank four-bar mechanism makes two fan doors one fan inwardly, and a fan is opened simultaneously outwardly, after staff or equipment after, makes two fans
Door simultaneously closes off, because pressure of the Action of Wind pressure on two fan doors is equal, direction is identical, and the opening direction of door is different, so two
Pressure on fan door is cancelled out each other, during door opening, as long as overcoming the steering resistance of door pivot and the frictional resistance of each department,
It can be easy to open, leak out in crack between a door and its frame and locate first-class sealing strip, by active force and the door automatic paste tightening of negative pressure, play sealing and make
With.
The advantageous effect of the utility model is mining balance air door：
1st, the air door has the advantages of opening flexibly and easily, wind pressure leakage loss is small, and effect is good, disclosure satisfy that production needs.
2nd, after having used the air door, the efficiency of switch air door is not only improved, but also reduces the personnel of switch air door, while
The hidden danger of switch air door is reduced, has effectively ensured the safety transported safely and pass through personnel towards air door.
