柜式七氟丙烷气体灭火装置中主要常用空瓶部件40、70、90、120、150升重量,划分为44、59、71、87、112Kg左右。有管网七氟丙烷气体灭火系统中主要常用空瓶部件70、90、120、150升重量,划分为68、81、100、120Kg左右。提供上述七氟丙烷灭火剂空瓶部件重量,有利于工程商、用户、监理、检考试收单位监督检测称重时,参考使用。

The often-used 40,70,90,120 and 150-liter empty cylinders in cabinet HFC-227ea gas extinguishing devices weigh around 44,59,71,87 and 112 kilograms respectively.The often-used 70,90,120 and 150-liter empty cylinders in HFC-227ea gas extinguishing equipment with pipe network weigh around 68,81,100,and 120 kilograms respectively.We provide the weights of the empty HFC-227ea fire extinguishing agent cylinders for the purpose of providing reference for engineering service providers,users,supervisors and inspection and accepting units in their weighing and checking.

步伐如下:发货前到厂家或项目装置现场瓶组间,随机抽检1~3瓶灭火剂瓶组,检测总重量;检测该瓶组是否处于密封性完好,无泄漏现象;若称重灭火剂瓶组总重量不敷,说明气体厂家少充装或经营者(工程商)修改了产品铭牌上标称重量,并不是气体灭火剂泄漏了。划排列出随机抽检灭火剂瓶组,空瓶部件重量(厂家提供和参考本文章中重量)、灭火药剂重量(比照设计院设计图纸重量)、驱动气体氮气重量,盘算出该瓶组七氟丙烷灭火药剂实际充装重量。

Measures to take:before the manufacturer delivers the products,go to the location of the manufacturer,or to the cylinder group room at project’s installation site and make random sampling of one to three fire extinguishing agent cylinder groups and check their total weights;check if the cylinder groups are stilled perfectly sealed with no sign of any leaking;if the total weight of a fire extinguishing agent cylinder group is below standard,it means the gas manufacturer has failed to fill enough gas into the cylinder,or the dealer(or engineering service provider)has changed the weight provided on the product plate,and not because there is leakage of the agent.Based on the result of the random sampling of fire extinguishing agent cylinder groups,list the weights of the empty cylinders(vs the weights provided by the manufacturer and the weight provided above),the weights of fire extinguishing agents(vs the weights provided on the drawings made by the design institute,the weights of propellant nitrogen gas,calculate based on the above information and find out the actual weight of HFC-227ea fire extinguishing agent fill into the cylinder group.

例:抽检有管网七氟丙烷气体灭火系统150升瓶组一瓶,盘算该瓶组七氟丙烷灭火药剂实际充装重量。

For example:sample-checking one of the cylinders of an 150-liter-cylinder group of a HFC-227ea gas extinguishing system with pipe network to find out the actual weight of HFC-227ea filled into this cylinder group.

检测与盘算如下:

①检测150升瓶组密封性,无泄漏;

②称150升瓶组重量,若为W=256.6Kg;

③检查该瓶组铭牌标称重量和设计院设计重量是否一致;

④检查该瓶组铭牌标称重量体现七氟丙烷药剂充装重量:122Kg,瓶组总重量:256.5Kg;

⑤盘算七氟丙烷灭火药剂充装重量首先依据厂家提供150升空瓶部件重量或参考本文章中150升空瓶部件重量W1=128.6kg;药剂W2与氮气W3重量为(256.6-128.6=128Kg,则氮气重量为W3=256.6-128.6-122=6Kg,氮气重量占七氟丙烷灭火剂重量的(6/122×100%)=4.9%,该氮气比例切合本文要求。七氟丙烷灭火药剂实际充装重为122Kg,切合划定要求。

The following are the checks and calculations:

①Check the sealing property of the 150-liter-cylinder group and make sure there is no leaking;

②Weigh the 150-liter-cylinder group,and if W=256.6Kg,

③Check if the weight provided on the product plate of the cylinder group is the same as the one designated by the design institute;

④Check the plate on the cylinder group to see if the weight of HFC-227ea filled into the cylinder is 122kg and the total weight of the cylinder group is 256.5kg;

⑤The calculation of the weight of the HFC-227ea agent filled in the cylinder should be based on the weight of the 150-liter empty cylinder provided by the manufacturer,or in reference to the weight of the 150-liter empty cylinder provided above:W1=128.6kg;the weight of the agent W2=256.6-128.6=128kg,while the weight of nitrogen gas W3=256.6-128.6-122=6kg,and nitrogen gas account for(6/122×100%=)4.9%of the weight of HFC-227ea,which conforms to the required rate provided above.The actual weight of HFC-227ea fire extinguishing agent filled in the cylinder is 122 kg,conforming to the required standard.

4.抗振动性和耐高、低温

4.Vibration and high/low temperature resistance

气体灭火系统产品出口项目(也叫气体灭火系统出口项目简称气体灭火系统出口或气体灭火设备出口)要求气体灭火系统各零部件具有良好的抗振动性能和耐崎岖温。能经受住海、陆、空立体运输的远程跋涉,不会因运输途中的风波、波动、崎岖温气象条件等造成设备的泄漏或误启动。气体灭火系统产品“一带一路”出口项目(也叫气体灭火系统出口项目简称气体灭火系统出口)所有零部件均应接纳抗震动设计,特别是灭火剂瓶组容器阀接纳双密封卧式压差式结构,该容器阀有两个气室,阀体内装置一活塞阀瓣,靠阀体内气压自动密封,需装置专用启动气缸和顶针部件,刺破容器阀启动气室密封膜片,方能开启灭火剂瓶组容器阀。该阀外表无任何开启手柄等零件,此结构容器阀*大特点是:抗碰撞、抗振动、耐+70℃高温和-30℃低温。确保了灭火剂不会因振动及崎岖温变革而泄漏和误启动。

All parts and components of the products for the gas fire extinguishing system product“Belt and Road”exporting project(also called gas fire extinguishing system exporting project,or gas fire extinguishing system exporting or gas fire extinguishing equipment exporting for short)should have good vibration resistance and high and low temperature resistance,can tolerance the long-distance trek of the three-dimensional transportation of sea,land and air and will not cause leakage or mis-initiation of equipment due to wind,waves,bumps,high and low temperature meteorological conditions during transportation.All parts and components of the products for the gas fire extinguishing system product“Belt and Road”exporting project(also called gas fire extinguishing system exporting project,or gas fire extinguishing system exporting for short)should be designed to resist vibrations,particularly the valves of the agent cylinder groups should adopt the double sealing horizontal pressure-gradient structure that has two air chambers,and a piston disc is installed inside the valve body that seals automatically thanks to the air pressure inside the valve body.A special starting cylinder and an ejector pin have to be installed to pierce the diaphragm seal of the air chamber of the cylinder valve in order to open the cylinder valve of the cylinder group.The valve does not have any opening handle or other prats.The most important feature of this kind of cylinder valve is that it is collision and vibration resistant and can withstand temperatures as high as+70℃and as low as-30℃.This can ensure that vibrations and temperature changes will not lead to the leakage of fire extinguishing agent and the cylinder can not be accidentally activated.
