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(mén)。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(mén),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(mǎn)物料后,開(kāi)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(mén)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。宿州上海五廠閥門(mén)金額溝槽閘閥是引進(jìn)歐洲高科技橡膠及閥門(mén)制造技術(shù)生產(chǎn)的，克服了橡膠老化及生銹等缺點(diǎn)。</p><div

電動(dòng)調(diào)節(jié)閥的流量特性直接影響系統(tǒng)的控制質(zhì)量和穩(wěn)定性，所以需要正確選擇。電動(dòng)調(diào)節(jié)閥流量特性分理想流量特性和工作流量特性。一般制造廠所提供的流量特性是理想流量特性，而電動(dòng)調(diào)節(jié)閥在實(shí)際應(yīng)用需要的則是工作流量特性。由于壓降比S小于1，工作流量特性上凸。因此，在選擇電動(dòng)調(diào)節(jié)閥流量特性時(shí)，應(yīng)先考慮選擇工作流量特性。然后，根據(jù)實(shí)際應(yīng)用選擇理想流量特性。在生產(chǎn)中常用的理想流量特性是線性、等百分比和快開(kāi)特性。而快開(kāi)特性主要用于雙位控制及程序控制，因此電動(dòng)調(diào)節(jié)閥流量特性的選擇通常是指如何合理選擇線性和等百分比理想流量特性。電動(dòng)調(diào)節(jié)閥在實(shí)際使用時(shí)，調(diào)節(jié)閥總是安裝在工藝管路系統(tǒng)中，電動(dòng)調(diào)節(jié)閥前后的壓差是隨著管路系統(tǒng)的阻力而變化的。因此，選擇調(diào)節(jié)閥的流量特性時(shí)，不但要依據(jù)過(guò)程特性，還應(yīng)結(jié)合系統(tǒng)的配管情況來(lái)考慮。
