If it becomes necessary for the door to close automatically, the best thing you can think of is to install a door closer. Adjustment and proper installation of this device will solve the problem of drafts once and for all, as well as overcome the laziness and forgetfulness of some visitors. Most often, such a device is installed in places where there is a high traffic of people: offices, entrances of residential buildings, shopping centers, train stations, etc. Often, a door closer is found in a private house, especially among those owners who love and appreciate their comfort and seek make your home as comfortable as possible.
Design and principle of operation
The simplest device that can be used to automatically close a door is a spring. The door closer implements the same principle of operation. At the heart of its work is the tension force that occurs when a spring is stretched, placed in its body, which, in turn, is filled with oil. The force and speed with which the closerthe door closes the passage, depend on the type of device and can be adjusted using the adjusting screws. The principle of operation is as follows: when the door is opened, the human force is transmitted through the piston and the thrust lever to the spring, which leads to its compression. In this case, the oil enters the vacated chamber through the valve. And after the person releases the door, the spring acts on the piston, and the liquid returns to the primary chamber. Note that the movement of oil is carried out through a hydraulic system, which consists of channels and which can be adjusted with screws. The more they are screwed into the case, the narrower the channel becomes, and the liquid flows more slowly.
Door closer: what is it like?
Some models of this device are equipped with a special valve that is responsible for the additional “click / pull” of the door, as well as a mechanism for delaying the closing of the wings. The latter function turns out to be very useful in cases where you need to bring in or take out a lot through the opening. The door closer can be installed on almost any type of door, from wooden to glass. The speed with which this device performs its work, as a rule, is regulated at two levels: the first is responsible for the closing speed along the major axis of the door leaf, and the second is for the final closing, which occurs a few centimeters in front of the box itself. In terms of its power, this device is from forty to one hundred and twenty kilograms. The right choice and installation of the doordoor closer largely depend on the weight of the leaf of the door itself. If it is too light, then a powerful device will quickly damage it. In the opposite situation, if you install a weak closer on a heavy door, it will not be able to perform its functions normally and will quickly break.
Installation and operation features
The installation of the fixture depends entirely on the direction in which the door opens (away from you or towards you). Its installation is carried out in the upper part of the door frame or on the door leaf itself (also in the upper part). In order for the door closer to serve for a long time, it should be remembered that it is impossible to pull, hold or fix the door with the help of various objects. From this, the piston and seals wear out in it, the gears break and oil flows out. Damaged closers cannot be repaired, and therefore you have to buy new ones instead.
