按閥門(mén)類別分為：閘閥：是作為截止介質(zhì)使用，優(yōu)點(diǎn)是閥芯可以全部打開(kāi)，此時(shí)介質(zhì)運(yùn)行的壓力損失**小。閘閥通常適用于不需要經(jīng)常啟閉，適用保持閘板全開(kāi)或全閉的工況。不適用于作為調(diào)節(jié)或節(jié)流使用。常用閘閥類型如：楔式閘閥、平行式閘閥、平行雙閘板閘閥、楔式雙閘板閘等。**常用的形式是楔式閘閥和平行式。連接方式為絲扣連接和法蘭連接；用于采暖、工藝管道系統(tǒng)，連接方式隨管道連接方式；≥dn50給水、煤氣管道上采用法蘭閘閥，截止閥：截止閥的閥桿軸線與閥座密封面垂直。閥桿開(kāi)啟或關(guān)閉行程相對(duì)較短，并具有非常可靠的切斷動(dòng)作，使得這種閥門(mén)非常適合作為介質(zhì)的切斷或調(diào)節(jié)及節(jié)流使用；介質(zhì)通過(guò)此類閥門(mén)時(shí)的流動(dòng)方向發(fā)生了變化，因此截止閥的流動(dòng)阻力較高于其它閥門(mén)。常用的截止閥有以下幾種：角式截止閥，常用于衛(wèi)生器具控制閥。直通式截止閥，常用于給水系統(tǒng)柱塞式截止閥：主要用于要求快速“開(kāi)”或“關(guān)”系統(tǒng)連接方式為絲扣連接，法蘭連接；用于蒸汽系統(tǒng)，連接方式隨管道連接方式；≤DN50給水系統(tǒng)采用絲接，大于≥采用法蘭連接。截止閥的優(yōu)點(diǎn)，密閉性好。球閥：球閥是由旋塞閥演變而來(lái)。它具有相同的旋轉(zhuǎn)90度提動(dòng)作，不同的是旋塞體是球體。西北居家暖通設(shè)備安裝施工商藥廠潔凈區(qū)壓差調(diào)節(jié)。</p><div

隨著空氣污染越來(lái)越嚴(yán)重，不少人選擇在室內(nèi)安裝空氣凈化器。市場(chǎng)上的主動(dòng)類空氣凈化器和雙重凈化類空氣凈化器一般只選擇一種主動(dòng)式的凈化技術(shù)。下面，和小編一起來(lái)了解一下五類空氣凈化技術(shù)。五類空氣凈化技術(shù)帶你了解空氣凈化器（圖片來(lái)源于網(wǎng)絡(luò)）目前市場(chǎng)上主要有銀離子凈化技術(shù)、負(fù)離子技術(shù)、低溫等離子技術(shù)、光觸媒技術(shù)和凈離子群技術(shù)。一、銀離子凈化技術(shù)簡(jiǎn)單地說(shuō)就是把銀塊離子化吹到空氣中以起到殺菌的效果，缺點(diǎn)是產(chǎn)品成本高，細(xì)菌殺滅率低，對(duì)***幾乎沒(méi)有殺滅特性。二、負(fù)離子技術(shù)主要原理是運(yùn)用靜電釋放負(fù)離子，吸附集中空氣中的粉塵起到降塵作用，同時(shí)負(fù)離子對(duì)空氣中的氧氣也有電離成臭氧的作用，對(duì)細(xì)菌有一定的殺滅作用，這類產(chǎn)品優(yōu)點(diǎn)是產(chǎn)品生產(chǎn)成本較低。三、低溫等離子技術(shù)主要原理是通過(guò)給氣體外加電壓至氣體的放電電壓，使氣體被擊穿，產(chǎn)生各種強(qiáng)氧化性的低溫等離子，并在極短時(shí)間內(nèi)把接觸到的污染物分解掉。這種技術(shù)一般用于工業(yè)廢氣處理，化學(xué)反應(yīng)后產(chǎn)生二次污染，若要應(yīng)用到家用空氣凈化器中，需要做人體安全測(cè)試以及相應(yīng)的二次污染處理技術(shù)。四、光觸媒技術(shù)光觸媒實(shí)際是利用半導(dǎo)體在光線的照射下，釋放強(qiáng)氧化力的自由基的技術(shù)。西北居家暖通設(shè)備安裝施工商</p><p
