style="text-indent:25px">船用閥門技術(shù)的發(fā)展概況：自七十年代以來，具有重量輕、尺寸小、密封性能好、啟閉迅速方便等優(yōu)點(diǎn)的球閥和蝶閥，已逐漸在艦船上得到應(yīng)用，并將越來越多地取代截止閥和閘閥，使艦船的性能得到改善。電動(dòng)閘閥、電動(dòng)截止閥、電動(dòng)通海閥、電液球閥、電液蝶閥、氣動(dòng)蝶閥等遙控閥門也逐步被部分艦船系統(tǒng)所采用，并開始應(yīng)用液動(dòng)閥門遙控系統(tǒng)，提高了艦船的現(xiàn)代化水平。船艦各系統(tǒng)所需的性能要求特殊的**閥門，如高壓蝶閥、先導(dǎo)型全啟式安全閥、海水電磁閥、高壓電液球閥、旋轉(zhuǎn)式液動(dòng)閘閥、**減壓閥、溫度調(diào)節(jié)閥、高壓空氣電磁閥、大排量疏水閥、通鳳蝶閥等，也能自行研制，提供艦船使用。</p><p style="text-indent:25px">船用閥門?相關(guān)知識(shí)：截止閥較明顯的優(yōu)點(diǎn)是：在開啟和關(guān)閉過程中，由于閥瓣于閥體密封面間的摩擦力比閘閥小，因而耐磨。開啟高度一般*為閥座通道直徑的1/4，因此比閘閥小的多。通常在閥體和閥瓣上只有一個(gè)密封面，因而制造工藝性比較好，便于維修。公稱壓力或壓力級(jí)：PN1.0-16.0MPa、ANSI CLASS 150-900、JIS10-20K 公稱通徑或口徑：DN10～500、NPS 1/2 ～36" 連接方式：法蘭、對(duì)焊、螺紋等適用溫度：-196℃～700℃ 驅(qū)動(dòng)方式：、氣動(dòng)、電動(dòng)、液動(dòng)、氣液聯(lián)動(dòng)、閥體材料：WCB、ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti、CF8(304)、CF3(304L)、CF8M(316)、CF3M(316L)、Ti。選用不同的材質(zhì)，可分別適用于水、蒸汽、油品、硝酸、醋酸、氧化性介質(zhì)、尿素等多種介質(zhì)。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">船用閥門工作原理：截止閥，也叫截門，是使用較普遍的一種閥門，它之所以廣受歡迎，是由于開閉過程中密封面之間摩擦力小，比較耐用，開啟高度不大，制造容易，維修方便，不*適用于中低壓，而且適用于高壓。截止閥的閉合原理是，依靠閥杠壓力，使閥瓣密封面與閥座密封面緊密貼合，阻止介質(zhì)流通。截止閥只許介質(zhì)單向流動(dòng)，安裝時(shí)有方向性。截止閥的結(jié)構(gòu) 長(zhǎng)度大于閘閥，同時(shí)流體阻力大，長(zhǎng)期運(yùn)行時(shí)，密封可靠性不強(qiáng)。截止閥開啟時(shí)，閥瓣的開啟高度，為公稱直徑的25%～30%時(shí)，流量已達(dá)到較大，表示閥門已達(dá)全開位置。所以截止閥的全開位置，應(yīng)由閥瓣的行程來決定。通常驅(qū)動(dòng)器分為單作用和雙作用兩種，根據(jù)閥的功能選擇。溫嶺自動(dòng)閥門控制系統(tǒng)</p><p style="text-indent:25px">液壓驅(qū)動(dòng)器是安裝在閥體上且由電磁閥控制的執(zhí)行器件。溫嶺自動(dòng)閥門控制系統(tǒng)</p><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(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(rùn)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(rùn)滑。此種結(jié)構(gòu)用于小口徑和溫度不高的地方。溫嶺自動(dòng)閥門控制系統(tǒng)</p><p
