The role of the door closer

The role of the door closer

The modern hydraulic door closer (referred to as the door closer) began with a patent registered by the Americans in the early 20th century. It is different from the traditional door closer, and achieves the buffering effect by throttling the liquid in the door closer. . The core of the design idea of the hydraulic door closer is to realize the control of the door closing process, so that various functional indicators of the door closing process can be adjusted according to people's needs. The significance of the door closer is not only to automatically close the door, but also to protect the door frame and the door body (smooth closing), and more importantly, the door closer has become a non-negligible executive part of the intelligent management of modern buildings.

Door closers are mainly used in commercial and public buildings, but they are also used in homes. They have many uses, the most important of which is to allow doors to close themselves, to limit the spread of fire and to ventilate buildings.
