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。</p><p>
