摘要： A fire collar or fire damper for location within a concrete slab of a building. The device incorporates a damper arrangement (12) and a heat detector (18, 19) comprising a metal alloy or lead which melts when a preset temperature is reached, causing the damper arrangement to seal off associated pipework or ducting.

摘要： A fire collar, for location in a concrete slab around a deformable conduit, has a housing with a passageway through which the conduit passes. The collar has the housing in which are located two compression springs with arms which are held against the force of the springs by fusible links. When the heat of a fire on one side of the slab causes the fusible links to soften or melt, the force of the springs causes the spring arms to rotate towards the conduit, engaging the conduit and collapsing it. An intumescent layer may be provided around the conduit to assist in collapsing it.

摘要： A fire damper for sealing a conduit which extends through a concrete slab to prevent fire and toxic gases from passing from one side of the slab to the other, includes a housing which has a partially spherical rotatable valve. The rotatable valve has an internal passageway of substantially the same diameter as an internal diameter of the conduit. The rotatable valve is rotatable within the housing between an open orientation whereby fluid flow through the damper is substantially unimpeded and a closed orientation. The rotatable valve is actuated by a heat detector in the form of two rings of lead alloy located between the housing and the rotatable valve. The damper may also include a deformable seal disposed between the housing and the rotatable valve.
摘要翻译：用于密封延伸穿过混凝土板的导管以防止火和有毒气体从板坯的一侧通过到另一侧的导管的防火阀包括具有部分球形的可旋转阀的壳体。可旋转阀具有与导管的内径基本上相同直径的内部通道。旋转阀可以在壳体内在开放方向之间旋转，由此流过阻尼器的流体流动基本上不受阻碍，并且闭合取向。可旋转阀由位于壳体和可旋转阀之间的两个铅合金环形式的热检测器致动。阻尼器还可以包括设置在壳体和可旋转阀之间的可变形密封件。
