新品安航FM200船用七氟丙烷灭火装置提供CCS船检证书原件

2.2设备的主要技术参数

The Main Technical Parameters of the Equipment

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 Plantconsists 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 StorageUnit

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 thestorage of HFC-227ea consists of HFC-227ea agent cylinder, bottle valve, checkvalve, collecting pipe, connecting pipe for releasing, discharge pipe,connecting pipe for discharge, etc.

2.3.2遥控施放站  Remote ControlReleasing 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 controlreleasing station consists of box, control cylinders, time-delay device,pressure gauge, etc. It can put out the fire in the cabin through manualoperation and pneumatic releasing the HFC-227ea in the cylinder.

2.3.3气控施放阀  Pneumatic ReleasingValve

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 valveis a kind pneumatic quick-opening valve, and it also can be named selectionvalve. Its working principle is: when the pilot gas pushes the stopcock in itsair cylinder, the crank moves and the spindle rotates, at this moment, the mainvalve is ready to open, and with the pressure of the agent itself, the mainvalve is open and then the agent is released. When it is in emergency, in orderto open the releasing valve, you can pull the hand shank directly. When the HFC-227eaagent is released by the man-made mistake, because the releasing valve isclosed, the HFC-227ea agent cannot release to the protection area.

2.3.4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 astop valve which can be opened rapidly through rotating 90 degree of the handshank.
