Floor Spring Door Closer

The Floor Spring Door Closer is a mechanical device installed on the edge of the door or under the floor to control the speed and force of the door closing. It mainly consists of a hydraulic spring installed on the ground and a set of adjustable control valves. When the door is opened, it uses hydraulic resistance to hold the door in the open position. It activates automatically when the door is released, closing the door slowly and smoothly with spring force. It has the function of adjustable strength, opening angle and closing speed. You can make adjustments according to actual needs to make the closing effect of the door safer and smoother. It is widely used in various buildings such as commercial, office, residential and public places, providing convenient access for people, and having functions such as fire prevention, sound insulation and heat preservation.

Working Principle

The working principle of a floor spring door closer involves a hydraulic mechanism that controls the movement of the door. When the door is opened, it compresses and stores energy. This energy is slowly released as the door is closed, creating a controlled closing action.
Inside, there is a piston and cylinder assembly that contains hydraulic fluid. When the door is opened, the piston is pushed down, compressing the fluid. This compression creates resistance, which helps to slow down the door’s movement.
As the door is released, the stored energy is gradually transmitted to the piston, causing it to rise and release the hydraulic fluid. This release of fluid creates a damping effect, which controls the speed of the door’s closing motion. The spring and hydraulic combination work together to ensure a smooth and controlled closing action.
It also has adjustable features, allowing users to adjust the closing force and speed according to their preferences. These adjustments can be made using valves or screws located on the floor spring unit. This ensures that the door closes safely and securely, providing a reliable closing mechanism for heavy doors.

Selection of Raw Material: Stainless Steel

The usage of stainless steel material is based on its advantageous properties and benefits. Stainless steel is a highly durable and corrosion-resistant material, making it an ideal choice for an application that requires prolonged exposure to various environmental conditions.
Due to its resistance to rust, stains, and corrosion, stainless steel ensures that the door closer remains in good working condition even when exposed to moisture, humidity, and other external factors. This durability extends the lifespan of the door closer, making it a cost-effective and reliable option.
Furthermore, stainless steel has excellent strength characteristics, providing the necessary structural integrity and support for heavy doors. It can withstand the weight and stress exerted during the opening and closing of the door, ensuring smooth and consistent operation over time.
Additionally, stainless steel offers an attractive and sleek appearance, enhancing the aesthetic appeal. This is particularly important when the door closer is visible or exposed, such as in high-end commercial buildings or modern architectural settings.

Overall, the use of stainless steel in the manufacturing of floor spring door closers ensures longevity, reliability, and visual appeal, making it a preferred choice for applications that demand high performance and durability.
