style="text-indent:25px">船舶閥門遙控系統(tǒng)的選用與分析：1、系統(tǒng)與控制類型：液壓驅(qū)動(dòng)閥門遙控系統(tǒng)如果用于**遙控的場合，建議用傳統(tǒng)控制方式的液壓驅(qū)動(dòng)系統(tǒng)，即帶有模擬管系圖的遠(yuǎn)程控制板，便于控制室集中遙控。如果是用于與其他控制系統(tǒng)集成的場合，則選擇計(jì)算機(jī)控制而且能裝卸載自動(dòng)程序編程。閥門的控制類型根據(jù)工況要求選用。開關(guān)控制用于只要求全開或全閉位置的閥門，開度控制用于要求閥位可連續(xù)控制的閥門。2、指示方式：所有非浸沒式閥門推薦用直接式指示，尤其是舷邊和艙底閥，這意味著信號(hào)應(yīng)該直接從閥/驅(qū)動(dòng)器給出。所有浸沒式閥推薦用間接指示。間接指示可減少電纜敷設(shè)量，從降低成本考慮，也可以用于某些非浸沒式閥門。揚(yáng)州智能閥門遙控系統(tǒng)報(bào)價(jià)船舶閥門遙控系統(tǒng)按閥門驅(qū)動(dòng)裝置分類主要有電力驅(qū)動(dòng)、氣動(dòng)驅(qū)動(dòng)、液壓驅(qū)動(dòng)以及電液驅(qū)動(dòng)等。</p><div

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(dòng)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(jì)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(gè)彈性密封圈實(shí)現(xiàn)的。兩個(gè)彈性密封圈用一個(gè)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(diǎn)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。</p><p

部件之間采用液壓管相連，部件較為分散，因此使用較為不便。電液式閥門遙控系統(tǒng)，所述遙控系統(tǒng)包括蝶閥組件和閘閥組件，蝶閥組件和閘閥組件通過電纜與集控臺(tái)相連，蝶閥組件包括多個(gè)蝶閥組，閘閥組件包括多個(gè)閘閥組，每個(gè)蝶閥組和每個(gè)閘閥組旁均設(shè)有測量信號(hào)發(fā)送器，多個(gè)測量信號(hào)發(fā)送器均通過測量信號(hào)傳輸線與集控臺(tái)相連接。本實(shí)用新型的進(jìn)ー步改進(jìn)在于每個(gè)所述蝶閥組均包括一驅(qū)動(dòng)頭和蝶閥本體，一驅(qū)動(dòng)頭置于蝶閥本體的上部，一驅(qū)動(dòng)頭與電纜相連。本實(shí)用新型的進(jìn)ー步改進(jìn)在于每個(gè)所述閘閥組均包括第二驅(qū)動(dòng)頭和閘閥本體，第二驅(qū)動(dòng)頭置于閘閥本體的ー側(cè)，閘閥本體與電纜相連。本實(shí)用新型的進(jìn)ー步改進(jìn)在于所述集控臺(tái)包括閥位狀態(tài)顯示器、電氣狀態(tài)顯示器、閥門遙控操作器和液位遙測器。本實(shí)用新型與現(xiàn)有技術(shù)相比具有以下優(yōu)點(diǎn)有利于安裝和操作，采用普通的PLC控制方法，更顯控制高效，且具有小尺寸大扭矩，就地操作，閥位指示、節(jié)能、低噪音的特點(diǎn)。液壓驅(qū)動(dòng)閥門遙控系統(tǒng)具有容易維護(hù)，適用范圍廣和成本較低的特點(diǎn)。</p><div
