In modern architectural design, the application of closed doorsters is extremely wide.In the field of fire safety, closed doors can be used with fire doors. When a fire occurs, the closed doors can keep the fire door closed and prevent the fire from spreading.At the same time, closure device is also an important component to achieve barrier -free traffic. For example, in medical institutions, elderly apartments and other places, the closed doors can ensure that the door fan can be closed after being pushed.The spread of bacteria and viruses in public areas.
Closer doors, a device widely used in the construction field, has an important impact on the experience and security of the door although inconspicuous.
The classification of closed doorsters is relatively diverse. According to the installation method, it can be divided into ground -shaped closed doors and top -mounted closed doors.The ground spring type closed door is installed at the bottom of the door fan, which is suitable for heavy doors such as fire doors, glass doors, etc., while top -mounted closed doors are installed on the top of the door fan. It is suitable for light doors such as wooden doors and PVC doors.In addition, there is an arm -hanging door closed door, which has a compact structure and is usually used in the scenario of small space or hidden installation.
The working principle of the closure device is relatively simple: the resistance generated by liquid or gas under control is used to achieve the control of the door.When the door is pushed, the hydraulic damper inside the closed doors will compress the liquid to generate resistance and open the door slowly; after the release, the hydraulic damper rebounds to help the door smoothly close, and gradually slow down at the close door frame until the door fan until the door fanFollow the door frame.The whole process is smooth and quiet, avoiding the occurrence of impact and noise.
The closed door device can be divided into three categories: ground spring type, arm hanging and vertical formula according to the installation method and function.The ground spring -type closed door is installed between the bottom of the door fan and the ground, which is suitable for heavy doors or places required to be used at high frequencies.The arm hanging door closed is installed on the door frame on the top of the door fan. It is connected to the door fan through the connecting rod. It is compact and easy to install. It is suitable for general business and residential doors.The vertical closed door is fixed directly on the door fan, occupying small space, suitable for the application scenario with limited space.
In addition to traditional hydraulic closed doors, in recent years, with the advancement of technology, electric closed doors have gradually entered the market.The electric closed doors can detect the opening and closing state of the door fan through the sensor, and automatically adjust the closing speed, and can even remotely control the opening and closing of the door fan.This provides more possibilities for intelligent buildings, and also brings convenience to peoples daily life.
In terms of design and manufacturing of closure, manufacturers pay attention to product stability and durability.High -quality closed -door device is usually made of corrosion -resistant materials, which can work in a harsh environment for a long time without damage.In addition, the adjustment performance of the closed doorser is also very important. Users can adjust the speed and intensity as needed to meet the different use environments and requirements.
In modern architectural design, the application of closed doorsters is extremely wide.In the field of fire safety, closed doors can be used with fire doors. When a fire occurs, the closed doors can keep the fire door closed and prevent the fire from spreading.At the same time, closure device is also an important component to achieve barrier -free traffic. For example, in medical institutions, elderly apartments and other places, the closed doors can ensure that the door fan can be closed after being pushed.The spread of bacteria and viruses in public areas.
As a precise mechanical device, the door closed is clever and functional, and it is an indispensable part of modern buildings.Whether it is improving security or increasing convenience, closure of the door plays an important role.With the continuous innovation of technology, the performance of closed doors will be more superior, and its application in future buildings will be more widely used.
