如截止閥、節(jié)流閥、減壓閥、止回閥等，如果裝倒裝反，就會(huì)影響使用效果與壽命（如節(jié)流閥），或者根本不起作用（如減壓閥），甚至造成危險(xiǎn)（如止回閥）。一般閥門，在閥體上有方向標(biāo)志。萬(wàn)一沒有，應(yīng)根據(jù)閥門工作原理，正確識(shí)別。<br/> 截止閥的閥腔左右不對(duì)稱，流體要讓其由下而上通過閥口，這樣流體阻力小（由形狀所決定），開啟省力（因介質(zhì)壓力向上），關(guān)閉后介質(zhì)不壓填料，便于檢修，這就是截止閥為什么不可安反的道理。其它閥門也有各自的特性。<br/> 閥門安裝位置，必須方便于操作<br/> 即使安裝暫時(shí)困難些，也要為操作人員的長(zhǎng)期工作著想。較好閥門手輪與胸口取齊（一般離操作地坪1.2米），這樣，開閉閥門比較省勁。落地閥門手輪要朝上，不要傾斜，以免操作別扭?？繅C(jī)靠設(shè)備的閥門，也要留出操作人員站立余地。<br/> 要避免仰天操作，尤其是酸堿、有害介質(zhì)等，否則很不安全。<br/> </p><p

分為進(jìn)料用閥、排氣用閥、進(jìn)氣用閥、出料用閥和切換用閥等。1.進(jìn)料用閥進(jìn)料用閥在氣力輸送中是用來(lái)切斷和接通物料從輸送點(diǎn)至輸送容器的閥門。合理選擇進(jìn)料閥的口徑?jīng)Q定了物料的流量以及整個(gè)系統(tǒng)的輸送能力。根據(jù)輸送介質(zhì)的不同,對(duì)其耐溫、耐腐蝕和耐磨性能也有不同程度的要求。2.排氣用閥排氣用閥是當(dāng)氣力輸送系統(tǒng)進(jìn)料時(shí),將輸送系統(tǒng)內(nèi)的空氣排到進(jìn)料倉(cāng)或者煙道中的閥門,以便于順暢下料,縮短進(jìn)料時(shí)間。其主要輸送介質(zhì)是帶有少量粉狀物料的空氣。3.進(jìn)氣用閥常作進(jìn)氣用閥有蝶閥、球閥、角座閥等。進(jìn)氣用閥的輸送介質(zhì)為壓縮空氣,所以對(duì)耐磨蝕性要求不高。4.出料用閥當(dāng)輸送設(shè)備充滿物料后,開啟進(jìn)氣閥和出料閥,讓物料在壓縮空氣的驅(qū)動(dòng)下在輸送管道系統(tǒng)內(nèi)輸送。所以出料閥的介質(zhì)為混有壓縮空氣的粉狀物料。作為出料閥的閥門一般有閘閥、球閥、圓頂閥等。5.分路用閥分路閥可以起到分流和匯流的作用,將物料從多點(diǎn)匯集到一點(diǎn)或者將物料從一點(diǎn)分散到多點(diǎn)。作為分路閥的有球閥、蝶閥或組合閥等,也有各廠家自制的分路閥。分路閥既可用于管路安裝,也可用于庫(kù)頂安裝。閘閥受到高溫高壓流體的作用，必然會(huì)產(chǎn)生變形及應(yīng)力。定遠(yuǎn)滬工閥門推薦</p><p
