Speed gate is subordinate to the access control system and is one of the important components of modern entrance and exit control. The door wing is driven by the control system to automatically open and close, and the operating mode can be selected through programming settings: as long as it is verified that the entrant has been authorized, the door wing opens automatically. It is closed after delay, and the delay time is adjustable.
Common speed doors are divided into two types, scissor doors and industrial swing doors, according to the different ways of door wing movement. Industrial swing doors appeared later than scissor doors and belonged to the second generation of speed-pass doors. The characteristic of this type of speed-pass door is that the direction of the door wings is forward and backward. The operation process is within the sight of the human body, making it safer. In addition, because the door wings do not need to be retracted into the box, the style of the industrial swing door is more varied. Due to the above characteristics, industrial swing doors are generally used in banks, corporate buildings, office buildings, etc.
The industrial swing door wing design of the speed-passing door makes the door wing closed by unauthorized persons entering directly in front of the pedestrian's line of sight. Will not cause harm to the human body due to pedestrians avoiding in time. The door wing is driven by a servo motor, the driving process is gentle, and the rotating torque is constant and less than 120NM. When the door wing is closed due to unauthorized entry, it can ensure that the impact force will not cause harm to the human body. It is safer and more reliable than other operating methods. In an emergency, when the flow of people is congested, under the strong impact of the crowd, the door wing of the speed-pass door can be pushed forward to safely evacuate the flow of people without causing accidental casualties.
Industrial swing doors help provide two-way access, suitable for warehouses, commercial kitchens, restaurants, supermarkets, department stores, etc. Both the front and the back are filled with acid and alkali resistant 304 stainless steel filled with aluminum honeycomb, which has the advantages of anti-corrosion and moisture resistance, and is thinner than ordinary stainless steel spring doors.
