规格

Halton BDH 抗爆阀可以在海上、路上、重工业通风系统中防止超压产生。BDH 抗爆阀可安装在矩形管道或墙壁开口中。当叶片处于开启位置时,该装置不会造成明显的压力损失、噪音或扰流。BDH有一个可调节的报警机制,以应对不同的风速和关闭压力要求。在抗爆阀外侧可以看到一个打开-关闭指示器。

不需要外部电源来运行抗爆阀。如果发生爆炸事件,压力波会关闭叶片。 有一个锁定机构,防止叶片在负相位打开。发生爆炸事件后,叶片保持锁定在关闭位置,直到重置(启用)抗爆阀。

Installation

The damper can be installed vertically outside of the building wall or between duct flanges. Also, horizontal installation is possible on the duct, floor or roof but only in the top-down blast direction.
The wall (or floor/roof) material can be concrete or steel.
For concrete wall installation, a wide-flange version is used and the damper is installed using anchor bolts.
For steel wall installation, the damper is installed using bolts or by welding.
Detailed installation information is available in the BDH installation, operation and maintenance manual.
