style="text-indent:25px">氣動式閥門遙控系統(tǒng)：該系統(tǒng)設(shè)備的配置比較簡單，因此較具有經(jīng)濟性，它的工作原理是壓縮空氣通過電磁閥的換向驅(qū)動氣缸內(nèi)的活塞達到開關(guān)閥的目的。它的主要配置為控制系統(tǒng)、二位五通電磁閥、氣動作用頭和閥，該系統(tǒng)利用船上已有的7-10bar控制空氣作為動力源，只有一路控制空氣接到電磁閥。從該系統(tǒng)原理圖可以看出，由于只需要一路壓縮空氣接到電磁閥，比較而言，該系統(tǒng)的控制空氣管子長度和其他型式系統(tǒng)相比，如遙控閥數(shù)量相同，所需要的數(shù)量要少得多。由于該系統(tǒng)動力源為7-10bar控制空氣，氣動動力頭體積比較大，操作遙控閥時消耗比較多的壓縮空氣，但氣動頭使用壽命長，閥可安裝在任何區(qū)域，工作安全可靠。對該系統(tǒng)而言，缺點是：一般船廠均采用紫銅管作為控制管，所以不可避免控制管路上有更多的管接頭，經(jīng)過長時間工作后，空氣管接頭容易泄漏，維護起來工作量大，海寧船舶閥門遙控系統(tǒng)哪家好，并且在維護時會影響系統(tǒng)工作。遙控閥的開關(guān)在控制臺上或計算機控制，海寧船舶閥門遙控系統(tǒng)哪家好，閥的開關(guān)位置通過控制臺上或計算機的指示燈顯示，海寧船舶閥門遙控系統(tǒng)哪家好。電-液式閥門遙控系統(tǒng)和液動式閥門遙控系統(tǒng)相比較，有所不同。海寧船舶閥門遙控系統(tǒng)哪家好</p><div

style="text-indent:25px">船舶閥門遙控系統(tǒng)的選用與分析：液壓驅(qū)動器：(1)驅(qū)動器類型：對于蝶閥，選用兩端帶有機械鎖的驅(qū)動器。對于球閥，選用可調(diào)節(jié)行程的驅(qū)動器。在較小液壓壓力下，驅(qū)動器能夠施加閥門開啟力矩的1.2倍。所有要求有安全功能的閥門采用開關(guān)量單作用驅(qū)動器，即使在系統(tǒng)失電或失壓時，驅(qū)動器有自動關(guān)閉功能將閥門關(guān)閉，應(yīng)避免用帶有開度控制功能的單作用驅(qū)動器。而雙作用驅(qū)動器則用于其他功能的閥門。(2)閥位指示：所有驅(qū)動器應(yīng)具有現(xiàn)場閥位指示器。遠距閥位直接指示由安裝在驅(qū)動器上的信號變送器發(fā)送。限位開關(guān)發(fā)送開關(guān)量信號，電位器則發(fā)送模擬量閥位信號。遠距閥位間接指示由液壓管路上液壓開關(guān)發(fā)送閥門啟閉信號，容積式指示器或流量計發(fā)送閥位信號。玉環(huán)船舶閥門遙控系統(tǒng)廠家遙控閥的開關(guān)在控制臺上或計算機控制，閥的開關(guān)位置通過控制臺上或計算機的指示燈顯示。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="海寧船舶閥門遙控系統(tǒng)哪家好,船用閥門遙控系統(tǒng)"

style="text-indent:25px">船用閥門截止閥：截止閥屬于強制密封式閥門，所以在閥門關(guān)閉時，必須向閥瓣施加壓力，以強制密封面不泄漏。當介質(zhì)由閥瓣下方進入閥門時，操作力所需要克服的阻力，是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門的力比開閥門的力大，所以閥桿的直徑要大，否則會發(fā)生閥桿頂彎的故障。近年來，從自密封的閥門出現(xiàn)后，截止閥的介質(zhì)流向就改由閥瓣上方進入閥腔，這時在介質(zhì)壓力作用下，關(guān)閥門的力小，而開閥門的力大，閥桿的直徑可以相應(yīng)地減少。同時，在介質(zhì)作用下，這種形式的閥門也較嚴密。我國閥門“三化給”曾規(guī)定，截止閥的流向，一律采用自上而下。本閥要水平安裝</p><p style="text-indent:25px">船用閥門常見問題該如何處理：1、為什么切斷閥應(yīng)盡量選用硬密封？切斷閥要求泄漏越低越好，軟密封閥的泄漏是較低的，切斷效果當然好，但不耐磨、可靠性差。從泄漏量又小、密封又可靠的雙重標準來看，軟密封切斷就不如硬密封切斷好。如全功能超輕型調(diào)節(jié)閥，密封而堆有耐磨合金保護，可靠性高，泄漏率達10～7，已經(jīng)能夠滿足切斷閥的要求。2、為什么套筒閥代替單、雙座閥卻沒有如愿以償？20世紀60年代問世的套筒閥，70年代在國內(nèi)外大量使用，80年代引進的石化裝置中套筒閥占的比率較大，那時，不少人認為，套筒閥可以取代單、雙座閥，成為第二代產(chǎn)品。到如今，并非如此，單座閥、雙座閥、套筒閥都得到同等的使用。這是因為套筒閥只是改進了節(jié)流形式、穩(wěn)定性和維護好于單座閥，但它重量、防堵和泄漏指標上與單、雙座閥一致，它怎能取代單、雙座閥呢？所以就只能共同使用。應(yīng)急操作單元分為甲板安裝和驅(qū)動器上直接安裝兩種方式。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="海寧船舶閥門遙控系統(tǒng)哪家好,船用閥門遙控系統(tǒng)" src="https://tyunfile.71360.com/UploadFile/yiwanchuanbo/637423554168131867/6421469.png"></div><p style="text-indent:25px">船用閥門根據(jù)截止閥的通道方向，分為：（1）直通式截止閥。（2）直流式截止閥：在直流式或Y形截止閥中，閥體的流道與主流道成一斜線，這樣流動狀態(tài)的破壞程度比常規(guī)截止閥要小，因而通過閥門的壓力損失也相應(yīng)的小了。（3）角式截止閥：在角式截止閥中，流體只需改變一次方向，以致于通過此閥門的壓力降比常規(guī)結(jié)構(gòu)的截止閥小。（4）柱塞式截止閥：這種形式的截止閥是常規(guī)截止閥的變型。在該閥門中，閥瓣和閥座是基于柱塞原理設(shè)計的。閥瓣磨光成柱塞與閥桿相連接，密封是由套在柱塞上的兩個彈性密封圈實現(xiàn)的。兩個彈性密封圈用一個套環(huán)隔開，并通過由閥蓋螺母施加在閥蓋上的載荷把柱塞周圍的密封圈壓牢。彈性密封圈能夠更換，可以采用各種各樣的材料制成，該閥門主要用于“開”或者“關(guān)”，但是備有特制形式的柱塞或特殊的套環(huán)，也可以用于調(diào)節(jié)流量。2.根據(jù)截止閥閥桿上螺紋的位置可分：（1）上螺紋閥桿截止閥：截止閥閥桿的螺紋在閥體的外面。其優(yōu)點是閥桿不受介質(zhì)侵蝕，便于潤滑，此種結(jié)構(gòu)采用比較普遍。（2）下螺紋閥桿截止閥：截止閥閥桿的螺紋在閥體內(nèi)。這種結(jié)構(gòu)閥桿螺紋與介質(zhì)直接接觸，易受侵蝕，并無法潤滑。此種結(jié)構(gòu)用于小口徑和溫度不高的地方。控制單元包括遠程控制板和現(xiàn)場控制板。海寧船舶閥門遙控系統(tǒng)哪家好</p><p style="text-indent:25px">閥門遙控系統(tǒng)一般有三種型式，即：氣動式、液動式和電-液式。海寧船舶閥門遙控系統(tǒng)哪家好</p><p style="text-indent:25px">液動式閥門遙控系統(tǒng)：該系統(tǒng)的主要配置為控制系統(tǒng)、液壓泵站、電磁閥箱、液壓驅(qū)動器和閥。液壓泵站可分為定量液壓泵和變量液壓泵，電磁閥箱根據(jù)布置場所可分為普通型和本安型，電磁閥箱數(shù)量可為一個或幾個。液動式閥門遙控的工作原理也是通過公共液壓泵站液壓泵工作，油泵輸出100～150bar液壓油工作壓力到電磁閥箱中各個電磁閥，通過電磁閥的換向和液壓油控制管到液壓驅(qū)動器控制閥門開關(guān)。每套液壓泵組配備二臺液壓泵，每臺液壓泵根據(jù)液壓工作壓力設(shè)定自動起停和互為備用。液壓泵站可選用定量液壓泵和變量液壓泵，他們不同之處在于定量液壓泵要配備蓄壓器，保證液壓油的工作壓力在范圍內(nèi)。海寧船舶閥門遙控系統(tǒng)哪家好</p><p
