真假的區(qū)別，當(dāng)然不止是山寨那么簡(jiǎn)單。在消防領(lǐng)域，也有不法商家造假冒偽劣消防器材！試想一下，發(fā)生火災(zāi)后，防火門不防火，滅火器也不能用，那得多***啊……<br/> 還是跟隨小編的步伐，<br/> 學(xué)學(xué)真假消防器材的辨別方法吧，<br/> Get 此項(xiàng)技能，<br/> 你就是這條街**亮的仔！<br/> 如何辨別消防器材真假？<br/> 一、查看產(chǎn)品標(biāo)識(shí)<br/> 一般來(lái)說，市面上賣的比較好的家用消防器材有滅火器、逃生繩、逃生面罩，防毒面具、防火毯等，隨著網(wǎng)絡(luò)的普及,網(wǎng)購(gòu)作為一種方便、快捷的購(gòu)物方式越來(lái)越被廣大網(wǎng)民朋友所接受,由于網(wǎng)上交易方便快捷,沒有地區(qū)限制,選擇范圍廣,**重要的是價(jià)格較為低廉,因此吸引一些私營(yíng)單位和個(gè)人的目光和購(gòu)買。小編建議大家購(gòu)買消防產(chǎn)品比較好到有規(guī)模、有銷售資質(zhì)的實(shí)體店購(gòu)買，并且在選購(gòu)時(shí)一定要仔細(xì)檢查產(chǎn)品的名稱，廠名廠址，產(chǎn)品的型號(hào)規(guī)格、編號(hào)、商標(biāo)、生產(chǎn)日期、主要技術(shù)指標(biāo)、執(zhí)行標(biāo)準(zhǔn)代號(hào)、使用方法、保質(zhì)期等內(nèi)容，滅火器和應(yīng)急燈還要有消防產(chǎn)品身份證標(biāo)識(shí)。<br/> </p><p style="text-indent:25px">目前閥門市場(chǎng)的經(jīng)銷商中主要存在的閥門造假的手段有:<br/> 1.用鐵、碳鋼制造閥門和修復(fù)廢品閥門以次棄好的閥門產(chǎn)品，這類產(chǎn)品一般在硬度和精度上存在很大誤差；<br/> 2.將劣質(zhì)低價(jià)的閥門、地方小廠的閥門產(chǎn)品打上大品牌廠商的注冊(cè)商標(biāo)，這類產(chǎn)品一般在品牌形象上以假亂真，以達(dá)到欺騙消費(fèi)者的目地；<br/> 3.假冒***大廠的用戶、經(jīng)銷商、代理商，甚至假冒廠家現(xiàn)貨門市部；<br/> 4.制作鋼印，把普通級(jí)閥門打字變成D級(jí)閥門；<br/> 5.在質(zhì)量閥門產(chǎn)品里攙入假貨出售；<br/> 6.在產(chǎn)品價(jià)格上欺騙消費(fèi)者，根據(jù)消費(fèi)者對(duì)閥門產(chǎn)品的實(shí)際了解情況以次充好，以假貨代替真貨出售；<br/> 如何分辨閥門真假？<br/> 1.外觀方面首先以閥門的軸體顏色為出色點(diǎn)進(jìn)行辨別。<br/> 閥門的外觀顏色可以充分的反應(yīng)出閥門產(chǎn)品的材質(zhì)情況，對(duì)于大多數(shù)的假冒閥門產(chǎn)品來(lái)說，一般均是在鋼材的選用上下文章。<br/> 大家都知道，鋼材價(jià)格也是決定著閥門產(chǎn)品價(jià)格的一個(gè)重要原因，因此一些商家則在鋼材使用上大下文章，降低鋼材型號(hào)，以次充好。使用普通鋼材、碳鋼、瑪鋼等材質(zhì)，更有甚者還會(huì)使用鐵管來(lái)代替鋼材產(chǎn)品。<br/>

但原理是相同的。水泵吸水管的吸水底閥是止回閥的變形,它的結(jié)構(gòu)與上述兩類止因閥相同,只是它的下端是開敞的,以便可使水進(jìn)入。7.減壓閥減壓閥是將介質(zhì)壓力降低到一定數(shù)值的自動(dòng)閥門,一般閥后壓力要小于閥前壓力的50%。減壓閥種類很多,主要有活塞式和彈簧薄膜式兩種?；钊綔p壓閥是通過活塞的作用進(jìn)行減壓的閥門。彈簧薄膜式減壓閥,是依靠彈簧和薄膜來(lái)進(jìn)行壓力平衡的。8.疏水閥疏水閥也叫阻汽排水閥、汽水閥、疏水器、回水盒、回水門等。它的作用是自動(dòng)排泄不斷產(chǎn)生的凝結(jié)水,而不讓蒸汽出來(lái)。疏水閥種類很多,有浮筒式、浮球式、鐘形浮子式、脈沖式、熱動(dòng)力式、熱膨脹式。常用的有浮筒式、鐘形浮子式和熱動(dòng)力式。(1)浮筒式疏水閥，浮筒式疏水閥，主要有閥門、軸桿、導(dǎo)管、浮筒和外殼等構(gòu)件組成。當(dāng)設(shè)備或管道中的凝結(jié)水在蒸汽壓力推動(dòng)下進(jìn)入疏水閥,逐漸增多至接近灌滿浮筒時(shí),由于浮筒的重量超過了浮力而向下沉落,使節(jié)流閥開啟。這樣使得筒內(nèi)的凝結(jié)水在蒸汽壓力的作用下經(jīng)導(dǎo)管和閥門排出。當(dāng)浮筒內(nèi)的凝結(jié)水接近排完時(shí),由于浮筒的重量減輕而向上浮起,使節(jié)流閥關(guān)閉,浮筒內(nèi)又開始積存凝結(jié)水。這樣周期性地工作,既可自動(dòng)排出凝結(jié)水,又能阻止蒸汽外逸。。巢湖分流閥門批發(fā)</p><p
