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?)仔細消除芯上各臺肩及閥孔沉割槽邊上的毛刺。仔細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，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?，F(xiàn)代柴油機HiMSEN閥芯價格合理英格索蘭

并定期清洗。3.檢查調(diào)節(jié)閥支撐。調(diào)節(jié)閥支撐使調(diào)節(jié)閥的各部件處于不受重力等影響的位置。如果支撐不當會造成調(diào)節(jié)閥閥桿與閥座不能對中，使變差增大，密封性能下降。因此，應(yīng)檢查調(diào)節(jié)閥支撐是否合適。4.消除氣源、液壓油等供應(yīng)能源的污物。氣源、液壓源是調(diào)節(jié)閥運行的能量來源。儀用壓縮空氣、液壓油中所含的雜質(zhì)會堵塞節(jié)流孔和管道，造成故障。因此，定期檢查氣源、液壓油，定期對過濾裝置進行排污十分重要。5.齒輪傳動裝置的檢查。對手輪機構(gòu)、電動執(zhí)行器和液動執(zhí)行器的齒輪傳動裝置應(yīng)定期檢查，添加潤滑劑，防止咬卡現(xiàn)象發(fā)生。應(yīng)檢查制動和限位裝置是否靈活好用。6.填料函檢查。應(yīng)檢查填料的磨損情況和壓緊力，定期更換填料函，保證填料能夠在起到密封的同時，減少其摩擦力的影口向。對無油潤滑的填料函不應(yīng)添加潤滑油。7.安全運行的檢查。對在性危險場所使用的調(diào)節(jié)閥和有關(guān)附件應(yīng)檢查其安全運行情況例如，密封蓋是否擰緊，安全柵的運行情況，電源供應(yīng)情況等，保證調(diào)節(jié)閥及有關(guān)附件能夠安全運行。8.運輸和保管。調(diào)節(jié)閥在運輸和保管期間，應(yīng)用**支架固定，防止松動；安裝在調(diào)節(jié)閥上的有關(guān)附件，如閥門定位器、手輪機構(gòu)等應(yīng)牢固。

在設(shè)計和安裝調(diào)節(jié)閥時，都力求在保證滿足使用要求的同時使成本較低，這時必須考慮調(diào)節(jié)閥、管件和管線、輔助設(shè)備三個方面。后兩項都是為了實現(xiàn)調(diào)節(jié)閥的功能，我們要力求這兩項較省，當然，這主要在數(shù)量和規(guī)格上下功夫。在安裝中，約有20%~30%的費用是這兩項產(chǎn)生的。例如，可調(diào)縮孔為了適應(yīng)設(shè)備連續(xù)生產(chǎn)的需要，許多工業(yè)系統(tǒng)都安裝有切斷閥和旁路閥，切斷閥用來隔斷調(diào)節(jié)閥，維修時需要用到旁路閥，多增加一個切斷閥或旁路閥，就要增加相應(yīng)的連接管線，這些都會增加費用;而有的配管方案，只需一個切斷閥就能起到維修時隔斷調(diào)節(jié)閥的全部作用，這樣的配管方案會節(jié)約一些安裝費用。2、調(diào)節(jié)閥的調(diào)試儀表設(shè)備在安裝過程中受到搬運或裝配引起的機械應(yīng)力的作用，會使其性能發(fā)生變化，一般來說，這種影響比較小。但為了可*起見，調(diào)節(jié)閥安裝后，在生產(chǎn)開車前應(yīng)進行現(xiàn)場調(diào)試，分線路調(diào)試和系統(tǒng)調(diào)試兩個步驟。線路調(diào)試用于檢查連接調(diào)節(jié)閥的信號線路、氣源管線或液壓管線的連接是否正確。1)調(diào)節(jié)閥輸入信號的連接通常，與閥門定位器一起檢查。調(diào)節(jié)閥輸入信號來自控制器，從控制器輸出一個起點信號，檢查調(diào)節(jié)閥是否在起點位置;輸出一個終點信號，檢查調(diào)節(jié)閥是否在終點位置。為此。英格索蘭

三通調(diào)節(jié)閥工作原理及結(jié)構(gòu)特點！一、三通調(diào)節(jié)閥介紹：三通調(diào)節(jié)閥，是由直行程電子式電動執(zhí)行機構(gòu)和采用圓筒型薄壁窗口形閥芯的三通合流（分流）閥組成。具有結(jié)構(gòu)緊湊、重量輕、動作靈敏、流量特性精確，直接接受調(diào)節(jié)儀表輸入的（4-20mADC0-10mADC或1-5VDC）等控制信號及單相電源即可控制運轉(zhuǎn)，實現(xiàn)對工藝管路流體介質(zhì)的自動調(diào)節(jié)控制，廣泛應(yīng)用于精確控氣體、液體、蒸汽等介質(zhì)的工藝參數(shù)如壓力、流量、溫度、液位等參數(shù)保持在給定值。適合于把一種流體通過三通閥分成二路流出或把兩種流體經(jīng)三通閥合并成一種流體的工況。電動三通調(diào)節(jié)閥三通閥有三個出入口與管道相連，相當于兩臺單座閥合成一體。按作用分為合流閥（兩進一通）與分流閥（一進兩通）。工作時，一路全開，一路全關(guān)，所以關(guān)閉時受力與單座閥相似，不平衡力大。三通閥閥芯與套筒閥的套筒一樣，其截留面積有開大窗和打小孔（噴射型）兩種，后者有降低噪音，減小共振的功能。二、三通調(diào)節(jié)閥結(jié)構(gòu)特點：1.三通調(diào)節(jié)閥是自動化控制系統(tǒng)中儀表的執(zhí)行單元，以AC220V電源電壓作動力，接受來自DCS、PLC系統(tǒng)或調(diào)節(jié)儀表、操作器等輸入的（4-20mA、0-10mA或1-5VDC）電流信號或電壓信號，即可控制運轉(zhuǎn)。現(xiàn)代柴油機HiMSEN閥芯價格合理</p></p><br
