1自力式調(diào)節(jié)閥的作用自力式調(diào)節(jié)閥都利用閥輸出端的反饋信號（壓力、壓差、溫度）通過信號管傳遞到執(zhí)行機(jī)構(gòu)驅(qū)動閥瓣改變閥門的開度，達(dá)到調(diào)節(jié)壓力、流量、溫度的目的。2自力式調(diào)節(jié)閥的優(yōu)點自力式調(diào)節(jié)閥是一個新的自力式調(diào)節(jié)閥種類。相對于手動調(diào)節(jié)閥，它的優(yōu)點是能夠自動調(diào)節(jié)；相對于電動調(diào)節(jié)閥，它的優(yōu)點是不需要外部動力。應(yīng)用實踐證明，在閉式水循環(huán)系統(tǒng)（如熱水供暖系統(tǒng)、空調(diào)冷凍水系統(tǒng)）中，正確使用這種閥門，可以很方便地實現(xiàn)系統(tǒng)的流量分配；可以實現(xiàn)系統(tǒng)的動態(tài)平衡；可以**簡化系統(tǒng)的調(diào)試工作；可以穩(wěn)定泵的工作狀態(tài)等。3自力式調(diào)節(jié)閥的分類自力式調(diào)節(jié)閥分為直接作用式和間接作用式兩種。直接作用式調(diào)節(jié)閥直接作用式調(diào)節(jié)閥又稱為彈簧負(fù)載式調(diào)節(jié)閥，其結(jié)構(gòu)內(nèi)有彈性元件：如彈簧、波紋管、波紋管式的溫包等，利用彈性力與反饋信號平衡的原理。間接作用式調(diào)節(jié)閥間接作用式調(diào)節(jié)閥，增加了一個指揮器（先導(dǎo)閥）它起到對反饋信號的放大作用然后通過執(zhí)行機(jī)構(gòu)，驅(qū)動主閥閥瓣運動達(dá)到改變閥開度的目的。如果是壓力調(diào)節(jié)閥，反饋信號就是閥的出口壓力，通過信號管引入執(zhí)行機(jī)構(gòu)。如果是流量調(diào)節(jié)閥，閥的出口處就有一個孔板。康明斯CUMMINS閥芯1096壽力溫控閥芯CALTHERM

電動閥門與氣動閥門的優(yōu)缺點氣動閥門氣動執(zhí)行器的執(zhí)行機(jī)構(gòu)和調(diào)節(jié)機(jī)構(gòu)是統(tǒng)一的整體，其執(zhí)行機(jī)構(gòu)有薄膜式和活塞式兩類。活塞式行程長，適用于要求有較大推力的場合；而薄膜式行程較小，只能直接帶動閥桿。由于氣動執(zhí)行機(jī)構(gòu)有結(jié)構(gòu)簡單，輸出推力大，動作平穩(wěn)可靠，并且安全防爆等優(yōu)點，在發(fā)電廠、化工，煉油等對安全要求較高的生產(chǎn)過程中有普遍的應(yīng)用。氣動執(zhí)行機(jī)構(gòu)的主要優(yōu)點：1、接受連續(xù)的氣信號，輸出直線位移（加電/氣轉(zhuǎn)換裝置后，也可以接受連續(xù)的電信號），有的配上搖臂后，可輸出角位移。2、有正、反作用功能。3、移動速度大，但負(fù)載增加時速度會變慢。4、輸出力與操作壓力有關(guān)。5、可靠性高，但氣源中斷后閥門不能保持（加保位閥后可以保持）。6、不便實現(xiàn)分段控制和程序控制。7、檢修維護(hù)簡單，對環(huán)境的適應(yīng)性好。8、輸出功率較大。9、具有防爆功能。 </p><p> 適用流體溫度有-40——+450℃；按溫度高低配用不同閥蓋可分常溫型、高溫型兩種氣動薄膜三通調(diào)節(jié)閥三、三通調(diào)節(jié)閥分類結(jié)構(gòu)：三通調(diào)節(jié)閥按流體的作用方式分為合流閥和分流閥兩類。合流閥有兩個入口，合流后從一個出口流出。分流閥有一個流體入口，經(jīng)分流成兩股流體從兩個出口流出。合流三通調(diào)節(jié)閥的結(jié)構(gòu)與分流三通調(diào)節(jié)閥的結(jié)構(gòu)類似。其特點如下：1、三通調(diào)節(jié)閥有兩個閥芯和閥座，結(jié)構(gòu)與雙座閥類似。但三通調(diào)節(jié)閥中，一個閥芯與閥座間的流通面積增加時，另一個閥芯與閥座間的流通面積減少。而雙座閥中，兩個閥芯和閥座間的流通面積是同時增加或減少的。2、三通調(diào)節(jié)閥的氣開和氣關(guān)只能通過選擇執(zhí)行機(jī)構(gòu)的正作用和反作用來實現(xiàn)。雙座閥的氣開和氣關(guān)的改變可直接將閥體或閥芯與閥座反裝來實現(xiàn)。3、三通調(diào)節(jié)閥用于需要流體進(jìn)行配比的控制系統(tǒng)時，由于它代替一個氣開控制閥和一個氣關(guān)控制閥，因此，可降低成本并減少安裝空間。4、三通調(diào)節(jié)閥也用于旁路控制的場所，例如，一路流體通過換熱器換熱，另一路流體不進(jìn)行換熱。當(dāng)三通閥安裝在換熱器前時，采用分流三通調(diào)節(jié)閥；當(dāng)三通調(diào)節(jié)閥安裝在換熱器后時，采用合流三通調(diào)節(jié)閥。由于安裝在換熱器前的三通閥內(nèi)流過的流體有相同溫度。復(fù)盛溫控閥芯

1、調(diào)節(jié)閥的安裝調(diào)節(jié)閥的安裝應(yīng)遵循國家有關(guān)標(biāo)準(zhǔn)，按照設(shè)計圖紙和設(shè)計文件的規(guī)定嚴(yán)格執(zhí)行。例如，建筑安裝工程質(zhì)量檢驗評定標(biāo)準(zhǔn)、工業(yè)自動化儀表施工及驗收規(guī)范、電氣設(shè)備安裝工程施工及驗收規(guī)范等;安裝所需的設(shè)備、輔助設(shè)備及主要材料應(yīng)符合現(xiàn)行國家標(biāo)準(zhǔn)的有關(guān)規(guī)定。調(diào)節(jié)閥及附件從出廠到安裝前，在運輸途中受到運輸工具所激發(fā)的隨機(jī)振動和裝卸時受到的各種沖擊，以及在運輸和儲存過程中，環(huán)境的溫度、濕度等變化，這些都可能造成調(diào)節(jié)閥及附件的性能發(fā)生變化。因此，有必要在安裝前進(jìn)行部分性能的檢驗。調(diào)節(jié)閥安裝前的檢驗主要包括下列內(nèi)容：外觀、靜態(tài)特性、泄漏量、空載全行程時間、耐壓強(qiáng)度、絕緣性能、氣密性和密封性等，其中前5項為必檢項目。當(dāng)然，對檢驗的場所也有一定的要求。例如：環(huán)境溫度要求在10～35℃;空氣相對濕度不大于75%;場地有足夠的空間，且光線充足或有照明條件;周圍不能有劇烈的振源和強(qiáng)磁場干擾;電源、氣源符合要求等。英格索蘭Ingersoll

2、避免卡緊現(xiàn)象的措施1)滑閥的液壓卡緊是共性問題，不僅換向閥有，其他液壓閥也存在，故傳統(tǒng)設(shè)計中都有避免卡緊的措施，嚴(yán)格控制閥芯、閥孔的制造精度，一般，閥芯和閥孔的圓柱度允差為μm，表面粗糙度：閥芯為，閥孔為，兩者配合間隙為～μm，并在閥芯的適當(dāng)位置(靠近高壓區(qū)側(cè))上開設(shè)環(huán)形槽，寬～1mm，深約，且環(huán)形槽要與外圓保證同心。2)閥芯的精度允許時，可以磨順錐(即小端朝向高壓區(qū))，結(jié)構(gòu)允許的情況下，可以采用錐形臺肩，臺肩小端朝向高壓區(qū)，有利于閥桿徑向?qū)χ小?)仔細(xì)消除芯上各臺肩及閥孔沉割槽邊上的毛刺。仔細(xì)消除熱處理件的氧化皮，且在轉(zhuǎn)序時利用工位器具防止零件磕碰。4)裝配過程中要防止零件磕碰，要注意清潔，各螺栓的預(yù)緊力要適當(dāng)，以防閥孔變形。5)要保證液壓系統(tǒng)的清潔度，防止油液被污染。6)提高閥體的鑄造質(zhì)量，減少閥芯的熱處理殘余應(yīng)力，防止彎曲變形。7)對于組合式換向閥，為了消除閥片間結(jié)合面平面度對卡緊的影響，可使其中一個面的中間部分低1～2μm，這既可減少閥孔的變形，又不致影響結(jié)合面的密封。康明斯CUMMINS閥芯1096</p></p><br
