一、概述：Outline

管道阻火器是適用于石化、化工、輕工等行業(yè)的可燃?xì)怏w輸送過程中的安全裝置。廠生產(chǎn)制造的管道阻火器是經(jīng)過嚴(yán)謹(jǐn)?shù)淖杌鹄碚撛O(shè)計和精密專用的機(jī)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 is the safety devices applicable to the petrochemical, chemical, light industry, combustible gas delivery process. I plant manufacturing Pipeline Fire is made ??after the a rigorous the flame arrester theory of design and precision dedicated processing machinery and equipment. According to fire resistance and fire retardant class can be divided into the the deflagration and resistance detonation two categories.

二、結(jié)構(gòu)設(shè)計：Structural design

產(chǎn)品由芯件和殼體兩部份組成，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（或在表面壓上丫形架）借以增強(qiáng)芯件的牢靠性，避免芯件被點(diǎn)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)"，就是火焰與器壁的碰撞進(jìn)行能量轉(zhuǎn)換，降低了溫度。以此原理來設(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 from both the core and the housing portion of the core member is the core, consists of two layers of ultra-thin stainless steel strip, a pressure wave N-shaped, the other a flat strip around the center of the circle is tightly entwined. So as to constitute an unlimited number of end face, a small triangle straight-through flow and a cross bracket (or Y-shaped frame) on the surface of the pressure inside the core member so as to enhance the robustness of the core pieces to avoid the media core member is lit the the resulting explosion pressure to break up. The medium from triangle throat through, the arrester through it is also to prevent the spread of flame in the pipeline, and its principle is the "wall effect", is the flame and the walls of the collision energy conversion, reducing the temperature. This principle to design the height of the triangular hole to prevent the passage of the flame, plus sufficient flow path length to absorb the heat of the flame to extinguish it in the core member, may avoid the gas at the other end of the core member is reignition sex.
