阻火器描述

管道阻火器是適用于石化、化工、輕工業(yè)等行業(yè)的可燃氣體輸送過程中的安全裝置。我廠生產(chǎn)制造的管道阻火器是經(jīng)過嚴謹?shù)淖杌鹄碚撛O(shè)計和精密專用的機械設(shè)備加工制造而成的。根據(jù)阻火性能和阻火等級可分為阻爆燃型和阻爆轟型兩大類。

Pipeline Fire safety devices applicable to the petrochemical, chemical industry, light industry and other industries combustible gas transportation process. I plant manufacturing Pipeline Fire is made after a rigorous the flame arrester theory design and precision processing machinery and equipment dedicated. Resistance deflagration and resistance detonation two categories can be divided according to fire resistance and fire retardant grade.

結(jié)構(gòu)設(shè)計 Structural Design

產(chǎn)品由芯件和殼體兩部分組成，芯件是核心，是由兩層超薄的不銹鋼帶，一條被壓成波N形，另一條平面鋼帶則將它圍繞圓心緊緊纏繞而成。從而構(gòu)成無數(shù)個端面，是小三角形直通流道，而且在芯件內(nèi)部有一個十字結(jié)構(gòu)的支架（或在表面壓上Y形架）借以增強芯件的牢靠性，避免芯件被點燃的介質(zhì)所產(chǎn)生的爆炸壓力沖散。介質(zhì)從三角形狹道中通過，阻火器也正是通過它來阻止火焰在管道中的蔓延，其原理為“器壁效應(yīng)"，就是火焰雨器壁的碰撞進行能量轉(zhuǎn)換，降低了溫度。從此原理來設(shè)計三角形孔的高度阻止火焰的通過。再加上足夠的流道長度來吸收火焰的熱量，使其在芯件中熄滅，避免了氣體在芯件的另一端被復(fù)燃的可能性。

Products offered by the two parts of the core member and the housing, the core member is a core, ultra-thin stainless steel bａnd composed of two layers, one being pressed into a wave-N-shaped, the other it is a flat strip tightly entwined around the center. Numerous end face so as to constitute a small triangle straight through the flow channel, and the core pieces of the internal structure of a cross bracket (or in the surface pressure on the Y-shaped frame) so as to enhance the robustness of the core parts, to avoid the media are core pieces are lit the explosion generated pressure to break up. Media through the narrow channel from the triangle, the flame arrester is precisely to prevent the spread of flame in the pipeline through which the principle of the "wall effect" Rain of Fire wall collision energy conversion, lower the temperature. From this principle in the design of the height of the triangle hole to prevent the passage of flame. Flow channel length plus enough to absorb the heat of the flame to extinguish it in the core member, to avoid the possibility of the gas at the other end of the core member is recrudescence.

適用范圍 Applicability

阻火器類別 Flame Arrester Category

概述：阻火器是安裝在石油、化工、化纖儲罐頂上，與呼吸閥、呼吸人孔、通氣孔配套使用的安全產(chǎn)品。其功能能為允許氣體通過，對火焰起到阻止、窒息的作用。

Overview: The flame arrester is installed in the petroleum, chemical industry, chemical fiber tank top with breathing valve, breathing manholes, vent supporting the use of security products. Its function is to allow gas through play to prevent the flame, the role of suffocation.

我廠生產(chǎn)的阻火器采用不銹鋼“N"形、雙層波紋帶為阻火芯件，殼體材料可根據(jù)貯存介質(zhì)的不同，有鋁合金、碳鋼和各種牌號的不銹鋼。其結(jié)構(gòu)有中石化北京設(shè)計院設(shè)計，科學(xué)合理，造型美觀。產(chǎn)品曾多次經(jīng)部天津消防科學(xué)所測試合格，并于1999年通過“科學(xué)技術(shù)成果"鑒定【(99)京設(shè)院鑒字02號】。

I plant the production of stainless steel flame arrestor "N"-shaped, double corrugated with flame arrester core pieces, shell material, depending on the storage medium, aluminum, carbon steel and various grades of stainless steel. Sinopec Beijing Design Institute structure, scientific and reasonable, attractive appearance. Products have repeatedly tested by the Ministry of Public Security, Tianjin Fire Science qualified and identified through scientific and technological achievements in [(99) the present,a court 02].

安裝與維護 Installation And Maintenance

管道阻火器與管路連接可水平安裝也可垂直安裝。定期檢查，一旦發(fā)現(xiàn)堵塞，應(yīng)用高壓蒸汽、壓縮空氣或有機溶劑清洗，如發(fā)現(xiàn)芯件機械性損壞或介質(zhì)腐蝕后，應(yīng)立即更換。

The Pipeline Fire and piping connections can be installed horizontally can also be mounted vertically. Periodic inspection, Once clogged, the application of high-pressure steam, compressed air, or organic solvent cleaning, such as the discovery of the core pieces of mechanical damage or corrosion medium, should be replaced immediately.
