氣動調(diào)節(jié)閥是石油,、化工,、電力、冶金等工業(yè)企業(yè)廣泛使用的工業(yè)過程控制儀表之-,?;ど?/span>
產(chǎn)中調(diào)節(jié)閥在調(diào)節(jié)系統(tǒng)中是*的,它是組成工業(yè)自動化系統(tǒng)的重要環(huán)節(jié),它如生產(chǎn)過程自動
化的手腳,。下面帶大家全面的了解氣動調(diào)節(jié)閥,。
工作原理
氣動調(diào)節(jié)閥就是以壓縮空氣為動力源,以氣缸為執(zhí)行器,,并借助于電氣閥門定位器,、轉(zhuǎn)換器,、
電磁閥、保位閥等附件去驅(qū)動閥門,實(shí)現(xiàn)開關(guān)量或比例式調(diào)節(jié),,接收工業(yè)自動化控制系統(tǒng)的控制信
號來完成調(diào)節(jié)管道介質(zhì)的:流量,、壓力、溫度等各種工藝參數(shù),。氣動調(diào)節(jié)閥的特點(diǎn)就是控制簡單,
反應(yīng)快速,,且本質(zhì)安全,不需另外再采取防爆措施。
氣動調(diào)節(jié)閥通常由氣動執(zhí)行機(jī)構(gòu)和調(diào)節(jié)閥連接安裝調(diào)試組成,,氣動執(zhí)行機(jī)構(gòu)可分為單作用式和
雙作用式兩種,,單作用執(zhí)行器內(nèi)有復(fù)位彈簧,而雙作用執(zhí)行器內(nèi)沒有復(fù)位彈簧。其中單作用執(zhí)行
器,,可在失去起源或突然故障時(shí),,自動歸位到閥門初始所設(shè)置的開啟或關(guān)閉狀態(tài)。
氣動調(diào)節(jié)閥根據(jù)動作形式分氣開型和氣關(guān)型兩種,即所謂的常開型和常閉型,,氣動調(diào)節(jié)閥的氣
開或氣關(guān),,通常是通過執(zhí)行機(jī)構(gòu)的正反作用和閥態(tài)結(jié)構(gòu)的不同組裝方式實(shí)現(xiàn)。
氣動調(diào)節(jié)閥作用方式
氣開型(常閉型)是當(dāng)膜頭上空氣壓力增加時(shí),閥門向增加開度方向動作,,當(dāng)達(dá)到輸入氣壓上
時(shí),,閥門處于全開狀態(tài)。反過來,,當(dāng)空氣壓力減小時(shí),,閥門向關(guān)閉方向動作,在沒有輸入空氣時(shí),,
閥門全閉,。顧通常我們稱氣開型調(diào)節(jié)閥為故障關(guān)閉型閥門。
氣關(guān)型(常開型動作方向正好與氣開型相反,。當(dāng)空氣壓力增加時(shí),閥門向關(guān)閉方向動作;空氣壓
力減小或沒有時(shí),閥門向開啟方向或全開為止,。顧通常我們稱氣關(guān)型調(diào)節(jié)閥為故障開啟型閥門。
氣開氣關(guān)的選擇是根據(jù)工藝生產(chǎn)的安全角度出發(fā)來考慮,。當(dāng)氣源切斷時(shí),調(diào)節(jié)閥是處于關(guān)閉位
置安全還是開啟位置安全,。
舉例來說,一個(gè)加熱爐的燃燒控制,,調(diào)節(jié)閥安裝在燃料氣管道上,根據(jù)爐膛的溫度或被加熱物
料在加熱爐出口的溫度來控制燃料的供應(yīng),。這時(shí),宜選用氣開閥更安全些,,因?yàn)橐坏庠赐V构?/span>
給,,閥門處于關(guān)閉比閥門處于全開更合適。如果氣源中斷,燃料閥全開,會使加熱過量發(fā)生危險(xiǎn),。
又如一個(gè)用冷卻水冷卻的的換熱設(shè)備,熱物料在換熱器內(nèi)與冷卻水進(jìn)行熱交換被冷卻,,調(diào)節(jié)閥安裝
在冷卻水管上,用換熱后的物料溫度來控制冷卻水量,在氣源中斷時(shí),調(diào)節(jié)閥應(yīng)處于開啟位置更安
全些,,宜選用氣關(guān)式即FO)調(diào)節(jié)閥,。

電動閥通常由電動執(zhí)行機(jī)構(gòu)和閥門組成。電動閥使用電能作為動力來通過電動執(zhí)行機(jī)構(gòu)來驅(qū)動閥
門,實(shí)現(xiàn)閥門的開關(guān)動作,。從而達(dá)到對管道介質(zhì)的開關(guān)目的,。電動閥門動作力距比普通閥門大,電動閥
門開關(guān)動作速度可以調(diào)整,結(jié)構(gòu)簡單,,易維護(hù),,可用于控制空氣、水,、蒸汽、各種腐蝕性介質(zhì),、泥漿,、
油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動,。
氣動閥門就是借助壓縮空氣驅(qū)動的閥門,。利用壓縮空氣推動執(zhí)行器內(nèi)多組組合氣動活塞運(yùn)動,傳力

電動閥與氣動閥各自的優(yōu)勢
1:氣動閥對氣體介質(zhì)和小管徑液體效果好,成本低,,維護(hù)方便。缺點(diǎn):受空壓氣壓力波動的影
響,,在北方冬季易受空壓氣含水影響,,造成傳動部分凍結(jié)、不動作,。一般氣動要比電動快,,電動的都是
手電兩用的,。而氣動要手、氣兩用的價(jià)格比較高,。
2:電動閥對液體介質(zhì)和大管徑氣體效果好,不受氣候影響,。不受空壓氣的壓力影響。缺點(diǎn):成本高,、
在潮濕環(huán)境不好,。
3、電動閥動作慢電動閥能做到防爆的品牌不是很多;氣動閥動作迅速,防爆相對來說價(jià)格比電動底
