    柜式七氟丙烷氣體滅火裝置中主要常用空瓶部件40、70、90、120、150升重量,分別為44、59、71、87、112Kg左右。有管網七氟丙烷氣體滅火系統中主要常用空瓶部件70、90、120、150升重量,分別為68、81、100、120Kg左右。提供上述七氟丙烷滅火劑空瓶部件重量,有利于工程商、用戶、監理、檢測驗收單位監督檢測稱重時,參考使用。

    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.

    措施如下:發貨前到廠家或項目安裝現場瓶組間,隨機抽檢1~3瓶滅火劑瓶組,檢測總重量;檢測該瓶組是否處于密封性完好,無泄漏現象;若稱重滅火劑瓶組總重量不夠,說明氣體廠家少充裝或經營者(工程商)修改了產品銘牌上標稱重量,并不是氣體滅火劑泄漏了。分別列出隨機抽檢滅火劑瓶組,空瓶部件重量(廠家提供和參考本文章中重量)、滅火藥劑重量(對照設計院設計圖紙重量)、驅動氣體氮氣重量,計算出該瓶組七氟丙烷滅火藥劑實際充裝重量。

    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:抽檢有管網七氟丙烷氣體滅火系統150升瓶組一瓶,計算該瓶組七氟丙烷滅火藥劑實際充裝重量。

    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.

    檢測與計算如下:

    ①檢測150升瓶組密封性,無泄漏;

    ②稱150升瓶組重量,若為W=256.6Kg;

    ③檢查該瓶組銘牌標稱重量和設計院設計重量是否一致;

    ④檢查該瓶組銘牌標稱重量表示七氟丙烷藥劑充裝重量:122Kg,瓶組總重量:256.5Kg;

    ⑤計算七氟丙烷滅火藥劑充裝重量首先依據廠家提供150升空瓶部件重量或參考本文章中150升空瓶部件重量W1=128.6kg;藥劑W2與氮氣W3重量為(256.6-128.6=128Kg,則氮氣重量為W3=256.6-128.6-122=6Kg,氮氣重量占七氟丙烷滅火劑重量的(6/122×100%)=4.9%,該氮氣比例符合本文要求。七氟丙烷滅火藥劑實際充裝重為122Kg,符合規定要求。

    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.抗振動性和耐高、低溫

    4.Vibration and high/low temperature resistance

    氣體滅火系統產品出口項目(也叫氣體滅火系統出口項目簡稱氣體滅火系統出口或氣體滅火設備出口)要求氣體滅火系統各零部件具有良好的抗振動性能和耐高低溫。能經受住海、陸、空立體運輸的長途跋涉,不會因運輸途中的風浪、顛簸、高低溫氣象條件等造成設備的泄漏或誤啟動。氣體滅火系統產品“一帶一路”出口項目(也叫氣體滅火系統出口項目簡稱氣體滅火系統出口)所有零部件均應采用抗震動設計,特別是滅火劑瓶組容器閥采用雙密封臥式壓差式結構,該容器閥有兩個氣室,閥體內安裝一活塞閥瓣,靠閥體內氣壓自動密封,需安裝專用啟動氣缸和頂針部件,刺破容器閥啟動氣室密封膜片,方能開啟滅火劑瓶組容器閥。該閥外表無任何開啟手柄等零件,此結構容器閥*大特點是:抗碰撞、抗振動、耐+70℃高溫和-30℃低溫。確保了滅火劑不會因振動及高低溫變化而泄漏和誤啟動。

    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.
