style="text-indent:25px">閥門遙控系統(tǒng)類型、組成、特點：閥門遙控系統(tǒng)基本上有以下幾種型式，按照執(zhí)行器驅(qū)動閥的方式，一般可分為三大類型：氣動式、液動式、電-液式。按照閥的安裝場所，可分為干式安裝和濕式安裝。按照閥的遙控控制方式，可分為模擬板開/關(guān)控制和計算機開/關(guān)控制。遙控閥的開/關(guān)位置指示反饋一般為觸點信號輸出到控制板指示燈指示該閥的工作狀態(tài)。如為干式安裝，微動開關(guān)直接裝在閥上或壓力開關(guān)裝在電磁閥箱內(nèi)控制液壓管上，通過24v或220v電源連接到模擬板或計算機上指示該閥的工作狀態(tài)。如為濕式安裝，流量計或壓力開關(guān)必須安裝在電磁閥箱內(nèi)控制液壓管上，根據(jù)開/關(guān)閥的需要液壓油流量大小和壓力大小輸出觸點信號。還有一種為遙控閥開度指示，它要求輸出的信號為4-20mA，在控制臺上連續(xù)指示閥的開/關(guān)百分比。鎮(zhèn)江船舶閥門控制系統(tǒng)直銷廠家閥箱包括高壓濾器、電磁閥、節(jié)流閥和供便攜式手動泵連接的快速接頭等元件。</p><div

當切至開閥操作時，兩位四通電磁閥a端通電動作，切至左位，高壓油路與管路B接通，回油管與管路A接通，此時壓力開關(guān)P感受不到壓力信號，常閉觸點1、2接通；② 流量開關(guān)（兩位兩通閥）進出口產(chǎn)生壓差，在先行流量信號的作用下的流量開關(guān)切至左位，此閥接通；③ 油缸B1口進油，A1口回油，帶動蝶閥逆時針轉(zhuǎn)動，直至液壓油缸行至限位，系統(tǒng)再次達到平衡。閥門遙控系統(tǒng)介紹：開、關(guān)閥電路情況分析：① 開、關(guān)閥動作時，流量開關(guān)Q斷開，此時PLC輸入口CL、OP均不得電；② 閥開到位后，流量開關(guān)Q閉合，壓力開關(guān)P觸點1、4閉合，此時PLC輸入口OP得電；③ 閥關(guān)到位后，流量開關(guān)Q閉合，壓力開關(guān)P觸點1、2閉合，此時PLC輸入口CL得電。</p><p style="text-indent:25px">船舶閥門遙控系統(tǒng)的選用與分析：液壓驅(qū)動系統(tǒng)：1、電磁閥箱：電磁閥箱接受由控制臺發(fā)出的控制信號或由計算機系統(tǒng)發(fā)出的指令信號。閥箱包括高壓濾器、電磁閥、節(jié)流閥和供便攜式手動泵連接的快速接頭等元件。2、執(zhí)行單元：執(zhí)行單元包括液壓驅(qū)動器和閥門。液壓驅(qū)動器是安裝在閥體上且由電磁閥控制的執(zhí)行器件。通常驅(qū)動器分為單作用和雙作用兩種，根據(jù)閥的功能選擇。單作用驅(qū)動器具有自動關(guān)閉功能。雙作用驅(qū)動器分為開/關(guān)型和閥位型。船舶上使用的大部分閥門為蝶閥，也有截止閥、球閥和閘閥等。3、應急操作單元：應急操作單元是通過便攜式手動泵或固定式手動泵操作驅(qū)動器。應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。甲板安裝方式用于浸沒式或操作人員難以到達的驅(qū)動器，以便于手動泵連接進行應急操作。直接安裝方式用于非浸沒式且操作人員可以直接到達的驅(qū)動器，用手動泵連接直接對驅(qū)動器進行應急操作。閥門遙控系統(tǒng)按照執(zhí)行器驅(qū)動閥的方式，一般可分為三大類型：氣動式、液動式、電-液式。</p><div

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)。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。鎮(zhèn)江船舶閥門控制系統(tǒng)直銷廠家</p><p

style="text-indent:25px">閥門遙控系統(tǒng)在船舶上是一個非常重要的系統(tǒng)，它一般用在貨船的壓載系統(tǒng)和貨、燃油輸送系統(tǒng)。該系統(tǒng)能在控制室遙控閥的開和關(guān)，使船員能方便地進行壓載水和燃油的調(diào)駁，獲得想要的船舶吃水狀態(tài)，來滿足船舶的各種工況要求。該系統(tǒng)用在油船貨油系統(tǒng)上，更是該船的經(jīng)濟命脈線，貨油的裝和卸全靠閥門遙控系統(tǒng)安全可靠的工作。閥門遙控系統(tǒng)還解決了有些場所船員不能隨時進入操作閥門和遠距離閥門操作工作量大的問題。閥門遙控系統(tǒng)的出現(xiàn)，較大減輕了船員的工作強度，減少不必要的工作危險，進一步保障了船員的安全，并保證了船舶的安全航行和經(jīng)濟效益。所以，閥門遙控系統(tǒng)的工作可靠性決定該船的安全和經(jīng)濟效益，各船公司對閥門遙控系統(tǒng)都已非常重視。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。本文介紹三種閥門遙控系統(tǒng)它們的驅(qū)動和控制型式的組成、工作原理和特點及閥門遙控系統(tǒng)中閥和執(zhí)行器及船級社規(guī)范要求。鎮(zhèn)江船舶閥門控制系統(tǒng)直銷廠家</p><p
