Lan Yu Hefei, automatic doors in the glass as the top product, the revolving door gives a warm and generous feeling, while creating a luxurious atmosphere, the spacious open facade and high-style design, called the building in the CBD. The new concept of the revolving door, unshakable foothold in the forefront of architectural trend of the times. But the revolving door of high cost is not generally acceptable. 
 l, the characteristics of automatic revolving door 
 The biggest advantage of automatic revolving door is that it is "always open, and never closed", that is for the staff, the door can always open the door to the building, it is always closed. Therefore, the automatic revolving door has a unique security features in development, but in terms of automatic revolving door personnel flow has no advantage, because the door's speed is fixed, each wing can accommodate between personnel is also limited. Automatic revolving door of each person has a flow calibration value. 
 Automatic revolving door is always open because it is always closed while the characteristics of the dynamic sealing effect to the conditions of lower phase in the frequent use of automatic doors for the other two better. Automatic revolving door as people flow will be limited, in large public places, or choose the other two automatic doors, automatic revolving door Bijing high cost. On both sides of the automatic revolving door is usually a separate automatic or manual door, on the one hand to increase capacity, on the other hand when the automatic revolving door fails, does not affect the person's pass. But in the static sealing effect, much less other automatic revolving door automatic doors, because the door way to determine the movement can only use the top seal. 
 2, the structure of automatic revolving door 
 Traditional three-wing and four-wing revolving door is this structure, the center of the door shaft mounted vertically through the bearing body to the ground, three or four wing-mounted in the center of divergence was the door axis, the angle between the doors of equal , between people, including the fan drive (clockwise) door to a manual revolving door. Installed above the center of the door axis control motors and other electrical components, which together with sensors and safety devices to become the automatic revolving door. This structure is stable, the use of high reliability and long service life. Considering the revolving door must stop playing in the seal, so the revolving door of each of three separate wings to accommodate more people, but the clear opening width of the smaller door. The four-wing revolving door can accommodate each separated by fewer people, but the clear opening width of the door but larger. 
 However, this revolving door wing and the central axis of the fixed width is not determined by the door too, so that the maximum diameter of the revolving door only about 4M. To solve this problem, engineers designed the center axis of the door into the middle of the showroom, the relative reduced width of door, door center increased rotation of the motor torque, so that the maximum diameter of the revolving door extended to 6M, the middle display Rooms have a good decorative effect. 
 As the channel door automatic revolving door should also be considered a state of emergency personnel quickly evacuated, so the revolving door of the wing to be able to manually push the power outage, it automatically with emergency opening function similar to using a special revolving door door hinge body connection hardware. But when the pressure is large, this structure likely to be blown open the doors. Hardware has become the strength of this automatic revolving door of one of the major quality problems. Automatic revolving door of international production plants has designed a special electromagnetic locks, making the door when a power outage can be promoted. 
 3. Automatic revolving door hanging (wings revolving door) 
 To further expand the revolving door personnel flow, increase the distance between the door revolving door, revolving door for natural to think the doors will be reduced to the number two. However, the wings can no longer use the revolving door has been the center of the door axis of the original structure, because the two doors of the center-driven torque is too large, the driving force of the force point and very small. In addition, the center of the door wings rotating shaft structure is difficult to achieve the emergency door open function. So the two wings of the revolving door hanging by the upper circular guide the design of the door to one or two motors. Control part of the same with the stability of the automatic revolving door. 
 It is worth mentioning that the two wings of the revolving door of the emergency opening function from structure has become very easy, that is set in the middle of an automatic or manual shift gate Swing. 
 Two wings of the door stop position of the revolving door has two, one is parallel to the plane door and the entrance, the middle sliding doors or manual swing gate can be used directly; the other is perpendicular to the plane door and the entrance, the doors at both ends of the arc will The two openings at the same time revolving door seal, get a good seal in the winter insulation. 
 4, all-glass automatic revolving door 
 Application of the revolving door of foreign architects are very cautious, not only because of its special features, but also because of the architectural features of its own is too prominent, easily and in stark contrast to the overall construction. Therefore, if the architect decided to use the automatic revolving door, it will be on the revolving door of the structure, material, lines, colors and other style elements to be coordinated with the overall architectural style comprehensive consideration and processing. The latest frameless all-glass revolving door that is suitable for the characteristics of some of the architectural style and developed. 
 From a structural point of view, all-glass automatic revolving door automatic revolving door with the same self-stability. Also divided into three wings and four two. Stability is also a ground support structure. The difference is, the drive in the ground. Connecting the upper and lower doors have a metal plate, metal plate fixed on the door of the doors, glass doors directly in the middle of the combination, omitting the central axis of the door, greatly increased the permeability of the door axis. Round top is a whole glass, door glass, fixed arc by arc, there is no metal fixed profiles. This structure and the concept of generation of aluminum and glass curtain wall glass curtain wall in particular the point entirely consistent in style coordination. The door is still the biggest drawback of restricted diameter. In addition, the waterproof seal at the bottom of the electrical part to be replaced regularly. Lyrics Home 5 U "O3 y # B-m 
 5. Automatic revolving door of the safe preparation. 
 Automatic door safety device can not be omitted. First, the activity between the wing and the fixed door is easy to clip people. Automatic revolving door entrances on both sides of the strip must be equipped with anti-pinch sensors. Second, the automatic revolving door rotation operation is relatively stable, when people walk through the revolving door speed must be consistent with its speed, otherwise, it is easy to send the main collision. A similar anti-collision function is to achieve automatic reverse function, but did not like the automatic sliding door opposite direction. Automatic revolving door of anti-collision, including the promotion of the reaction of people. Is caused by man-made to promote the function of automatic revolving door one of the main obstacles.
