Hefei Lan Yu glass as the top product in the automatic doors, revolving door gives a warm and generous feeling, while creating a luxurious atmosphere, the spacious open facade and high-style design, called the buildings in the CBD. The new revolving door concept, unassailable foothold in the forefront of architectural trend of the times. But the revolving door of high cost is not an ordinary person can accept. 
 l, automatic revolving door is characterized by 
 The biggest advantage of automatic revolving door is that it is "always open, but 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 the personnel flow in automatic revolving door, but there is no advantage, because the gate speed is fixed, each wing can accommodate between personnel is also limited. Each has a calibrated automatic revolving door of personnel flow values. 
 Automatic revolving door is always open at the same time because they always turn off features to make it dynamic sealing effect of commonly used terms in the lower phase is better for the other two automatic doors. As the automatic revolving door of the flow of people is limited, in large public or choose the other two automatic doors, automatic revolving door Bijing high cost. Usually both sides of the automatic revolving door automatic or manual swing gate separate the one hand, increase traffic capacity on the other hand when the automatic revolving door fails, does not affect people through. But in the static sealing effect, much less other automatic revolving door automatic doors, because it determines the way of door movement only tops sealed. 
 2, the structure of automatic revolving door 
 Traditional three-wing and four-wing revolving door is this structure, the center's door shaft through the bearing bodies installed vertically in the ground, three or four door-mounted wing was a divergence in the center door axis, equal to the angle between the door , between people, including fan-driven (clockwise) doors, has become a revolving door manually. Installed above the central axis of the door motors and other electrical control components, together with sensors and safety devices, has become the automatic revolving door. This structure is stable, the use of high reliability, long service life. Considering the revolving door must stop playing in the seal, so the three-wing revolving door separated each can accommodate more people, but the door clear opening width smaller. The four-wing revolving doors can accommodate each separated by fewer people, but the door clear opening width is larger. 
 However, this revolving door wing and the central axis of the fixed width is not determined by the door too, so this revolving door of the maximum diameter of only about 4M. To solve this problem, engineers designed the center axis into the middle of the door show room, the relative decrease of the width of doors, an increase of the center of rotation of the motor torque door, so that the maximum diameter of the revolving door to expand to 6M, the middle display rooms have a good decorative effect. 
 As the channel gate automatic revolving door must also consider the rapid evacuation of emergency personnel, so the door wing revolving door to be able to manually push the power outage, so with emergency opening function of the automatic revolving door similar to using a special door hinge body connection hardware. But when air pressure is large, this structure can easily be blown open doors. Hardware strength has become the automatic revolving door of one of the major quality problems. International automatic revolving door manufacturer has designed a special electromagnetic locks, a power outage when the doors can be promoted. 
 3. Automatic revolving door hanging (wings revolving door) 
 To further expand the revolving door personnel flow, expand the distance between the door revolving door, it is natural to think of the revolving door by door number two. However, the two wings of the revolving door can never again be the center of the door using the original shaft structure, because the two doors of the Centre-driven torque is too large, and the driving force of the force point and few. In addition, the center axis of the structure difficult to realize the door wings revolving door emergency opening function. So the upper wings with a circular revolving door hung the door rail design, with one or two motor-driven. Control part of the automatic revolving door with the same stability. 
 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 sliding doors or manual swing gate. 
 Wings of the door position to stop the revolving door has two, one is the entrance door and the plane parallel to the middle of the automatic sliding doors or manual swing gate can be used directly; the other is the entrance door and the plane perpendicular to the door 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 its own architectural features are too prominent, easily and in stark contrast to the overall construction. So if you decide to use an architect automatic revolving door, then they would on the revolving door of the structure, material, lines, colors and other style factors to the overall architectural style with a comprehensive consideration and coordinated treatment. The latest frameless all-glass revolving door that is suitable for certain characteristics and architectural style 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. But also the stability of the ground support structure. The difference is that drive in the ground. Connecting the upper and lower doors have a metal plate, metal plate fixed on the doors of the doors, glass doors in the middle of a combination of direct, omit the center axis of the door, greatly improved the permeability of the door shaft. The top is a whole round flat glass, door glass, fixed circular arc using no metal fixed profiles. This structure and the concept of generation of aluminum curtain wall glass curtain wall, especially point entirely consistent in style coordination. The door is still the biggest drawback of restricted diameter. In addition, the electrical part of the waterproof seal at the bottom must be regularly replaced. 

 5. Automatic revolving door of the safe preparation. 
 Automatic revolving door safety device can not be omitted. First, the activity and fixed-wing door is easy to clip between people. Automatic revolving door entrances on both sides of the strip must be equipped with anti-pinch sensor. Second, the automatic revolving door rotation operation is relatively stable, people walking through the revolving door at the speed of its speed must be consistent, otherwise, it is easy to send the main collision. Anti-collision function is similar to the auto-reverse feature to achieve, just like the automatic sliding door did not reverse movement. Automatic revolving door of anti-collision, including the promotion of human reaction. To promote the cause of man-made automatic revolving doors feature one of the main obstacles.
