What is a door closer? How does it work?
Door closers are devices that allow you to securely close doors. They are essential when it is necessary to guarantee, always or in the event of fire, a controlled closure . In fact, the main purpose of a door closer is to regulate the closing of the door.
A common door closer is made up of several parts which can vary depending on the model: a die-cast aluminum housing, the spring, the piston, the adjustment screws (commonly called valves), the gears, the needle bearing, a rubber seal and finally the stops.
Door closer spring: the mechanism for regulating the closing of the door
The door closer mechanism is based on the spring of the door closer itself which is compressed when the door is opened. As the spring is compressed it accumulates the energy needed to close the door when necessary. Gears and slats move the piston, while oil flows through internal channels into the free part of the door closer body. During the spring return phase, the latter straightens and the door closes softly.
Door closer adjustment: our advice
Door closer adjustment is a relatively simple process and can easily be done by hand. Adjustment of the door closer should be carried out 1-2 times a year, depending on the number of uses per day. It may be necessary to make an extraordinary adjustment even in the event of small malfunctions, especially during the change of season. In fact, in summer and winter the climatic conditions change and therefore also the state of the oil inside the door closer.
The adjustment of a door closer must be carried out based on the type of door closer itself. In fact, there are overhead door closers on the market that work on the upper part of the door and floor door closers that block the lower part of the entrance.
To adjust an overhead door closer (which is located at the top of the door) we recommend that you correctly adjust the different screws and valves located on the housing panel. Overhead door closers are mounted at the top of the door leaf, so it shouldn't be too difficult to make these adjustments.
The adjustment of the floor door closers, almost invisible to visitors, takes place by applying regulating mechanisms.
How to reduce the closing force of the door closer?
After installing a door closer it may be necessary to make one more additional adjustment. This is to avoid having to make an effort when opening the door. Just release the valve slightly to allow easier movement.
This valve can be located at the end or on the front side of the door closer, depending on the model. To understand without any doubt where it is located, just look at the door closer reference manual where the manufacturer clearly indicates all the positions of the components and elements of the closing mechanism.
How to leave the door closer in the open position?
Sometimes it may be useful to leave the door open. The door closer must therefore be adjusted to the open position, which must be maintained for a long period. In some door closer models there is a special function to keep open: to activate this mode the door must be opened by approximately 90 degrees and then the appropriate lock must be closed. After these simple operations the door leaf can be left open to the adjusted degree.
When you want to close the blocked door you just have to pull it towards you, deactivating the door closer block. The door will move normally, closing without stopping.
Advice on the use of door closers
Here are our recommendations on using door closers for sale online on Windowo:
avoid sudden movements as much as possible when moving the door, maintaining a normal opening and closing speed of the door;
remember that in different models you can increase or decrease the reaction speed of the door closer by rotating the valve clockwise or in the opposite direction;
if you rotate the adjustment nut you can make corrections to the tension of the door closer spring;
through the valve you can change the opening angle of the door to open easily and smoothly.
