中国船级社认可CCS船检船用固定式FM200七氟丙烷灭火系统装置
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.
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, and it also can be named selection valve. Its working principle is: when the pilot gas pushes the stopcock in its air cylinder, the crank moves and the spindle rotates, at this moment, the main valve is ready to open, and with the pressure of the agent itself, the main valve is open and then the agent is released. When it is in emergency, in order to open the releasing valve, you can pull the hand shank directly. When the HFC-227ea agent is released by the man-made mistake, because the releasing valve is closed, the HFC-227ea agent cannot release to the protection area.
4快开阀 Quick-opening Valve
快开阀是一种手柄只板转90°，即可迅速打开的截止阀。
Quick-opening valve is a stop valve which can be opened rapidly through rotating 90 degree of the hand shank.
5信号反馈装置 Signal Feedback Device
信号反馈装置由压力信号发送器组成
Signal feedback device consists of pressure signal transmitter.
施放信号输出：常开无源触头
Out-put of release signal: normally open passive contact
超压泄放信号输出：常开无源触头
Overpressure release input signal: normally open passive contact
6分配管系和喷嘴 Distribution Piping System and Nozzle
七氟丙烷分配管系是输送七氟丙烷灭火剂的通道，是本系统的重要组成部分。喷嘴是喷洒七氟丙烷灭火剂的部件，喷嘴设置应力求使七氟丙烷灭火剂均匀地喷向保护区域。
HFC-227ea distribution piping system as an access to the transportation of HFC-227ea agent is an important part of the plant. Nozzle is a component used for spraying the HFC-227ea agent, and the installation of the nozzle shall make the HFC-227ea agent spray to the protection area uniformly.
