自动门闭门器的种类

Type of automatic door closed door

暗藏式闭门器，是将自动门闭门器镶嵌于门扇的框内。当活动扇关闭时，将完全看不见闭门器。这种闭门器的关键规格是闭门器的厚度，这关系到门扇的厚度。目前，世界上最薄的暗藏式闭门器仅仅只有28mm，一般厚度的活动扇都可以假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵安装。此类闭门器的安装，会破坏到活动扇的框，不能用于当做防火门。

The hidden door closer is to set the automatic door closer in the frame of the door leaf. When the active fan is closed, the door closer can't be seen completely. The key specification of the door closer is the thickness of the door closer, which is related to the thickness of the door leaf. At present, the world's thinnest concealed door closer is only 28mm, and the general thickness of the movable fan can be installed. The installation of such a door closer will destroy the frame of the movable fan and cannot be used as a fire door.

还有一种时与合页结合的闭门器，也可达到一定的美观效果。这种闭门器的作用力臂接近合页，力矩很小，适用的范围有限。

There is also a door closer combined with hinge, which can also achieve a certain aesthetic effect. The closing force of the door closer is close to the hinge, the torque is very small, and the applicable scope is limited.
