fire flap 这个词在ABS MODU里没有找到。这里出现过两次，但没有定义，原文如下：
在LR 规范：Rules and Regulations for the Classification of Naval Ships, January 2006, incorporating Notice No. 1，Volume 2 Machinery and Engineering Systems，Part 11 Support Systems，Chapter 2 Heating, Ventilation and Cooling Arrangements，Section 3 System arrangements，
3.3 Galleys 3.3.1. The following arrangements are to be incorporated in ventilation systems within galleys:
(a). All trunking is to be of steel or stainless steel.
(b). Exhaust terminals above equipment such as fryers, grills, etc, are to be fitted with grease filters that can easily be removed and cleaned.
(c). Exhaust branches, fitted with grease filters, are to be protected by fire flaps within the galley. The flaps are to be sited in the exhaust trunking between the canopy and the exit from the galley, arranged to close in the direction of air flow and be readily operable from both within and outside the galley.
(d). CO2 injection or other fire extinguishing means facilities are to be fitted.
Exhaust systems from galleys are normally to be led to atmosphere. In the case of ships fitted with NBC Protection and when identified in the design statement, the galley ventilation system may be designed to recirculate air and, to limit food smells, odour filtration is to be provided. If the exhaust is led to atmosphere in ships fitted with NBC Protection, the air loss is to be considered when assessing the NBC arrangements.
3.3.2. In addition to those fitted in galley systems, fire flaps are also to be fitted:
(a). In ventilation trunks that pass through designated fire barriers.
(b). In ventilation trunks that pass through watertight bulkheads where this penetration occurs within the lines of weathertight and watertight integrity as defined in Vol 1, Pt 3, Ch 2.
