2.3装置组成  Plant Components
七氟丙烷灭火装置是由灭火剂储存装置和遥控施放站、气控施放阀（选择阀）、快开阀、信号反馈装置、分配管系及喷嘴等组成。
HFC-227ea Fire Suppression Plant consists of agent storage unit, remote control releasing station, pneumatic control valve (selection valve), quick-opening valve, signal feedback unit, distribution pipe system, nozzles, etc.
2.3.1灭火剂储存装置  Agent Storage Unit
本装置由七氟丙烷储瓶、瓶头阀、止回阀、集流管、施放连接管、泄放管、泄放连接管等组成，用于储存七氟丙烷灭火剂。
The unit used for the storage of HFC-227ea consists of HFC-227ea agent cylinder, bottle valve, check valve, collecting pipe, connecting pipe for releasing, discharge pipe, connecting pipe for discharge, etc.
2.3.2遥控施放站  Remote Control Releasing Station
船用遥控施放站由箱体、控制气瓶、延时装置、压力表等组成。用于手动操作气动释放七氟丙烷储瓶对舱室进行灭火作业。
Marine remote control releasing station consists of box, control cylinders, time-delay device, pressure gauge, etc. It can put out the fire in the cabin through manual operation and pneumatic releasing the HFC-227ea in the cylinder.
2.3.3气控施放阀  Pneumatic Releasing Valve
气控施放阀是一种气控快开阀，又叫选择阀，其工作原理为当控制气体推动所属的气缸活塞，带动曲柄动作，使转轴旋转，即主阀处于可开启状态，在灭火剂本身压力作用下主阀打开实现灭火剂释放动作，应急时也可直接扳动施放阀手柄，从而打开施放阀，当发生人为误动七氟丙烷储瓶的瓶头阀而导致七氟丙烷误放时，由于施放阀尚处于关闭状态，可确保七氟丙烷不致误放至被保护处所。
Pneumatic releasing valve is a kind pneumatic quick-opening valve, a
