style="text-indent:25px">常用的截止閥有以下幾種：(1）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。(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）柱塞式截止閥：這種形式的截止閥是常規(guī)截止閥的變型，天津閥門。在該閥門中，閥瓣和閥座通常是基于柱塞原理設(shè)計(jì)的，天津閥門。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)，天津閥門，也可以用于調(diào)節(jié)流量。運(yùn)輸過程中要采取措施保證包封不破損。天津閥門</p><div

style="text-indent:25px">閥門型號編排：閥門型號通常應(yīng)表示出閥門類型、驅(qū)動(dòng)方式、連接形式、結(jié)構(gòu)特點(diǎn)、密封面材料、閥體材料和公稱壓力等要素。閥門型號的標(biāo)準(zhǔn)化對閥門的設(shè)計(jì)、選用、銷售提供了方便。當(dāng)今閥門的類型和材料越來越多，閥門的型號編制也愈來愈復(fù)雜。我國雖有閥門型號編制的統(tǒng)一標(biāo)準(zhǔn)，但愈來愈不能適應(yīng)閥門工業(yè)發(fā)展的需要。目前，閥門制造廠一般采用統(tǒng)一編號方法；凡不能采用統(tǒng)一編號的方法，各制造廠均按自己的需要制訂編號方法。《閥門型號編制方法》適用于工業(yè)管道用閘閥、節(jié)流閥、球閥、蝶閥、隔膜閥、柱塞閥、旋塞閥、止回閥、安全閥、減壓閥、疏水閥。它包括閥門的型號編制和閥門的命名。九江閥門批發(fā)閥門存放環(huán)境需注意，應(yīng)存放在干燥通風(fēng)的室內(nèi)，且堵塞通路兩端。</p><div

style="text-indent:25px">關(guān)于各種閥門的特點(diǎn)和區(qū)別：蝶閥蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°~90°之間，旋轉(zhuǎn)到90°時(shí)，閥門則牌全開狀態(tài)。蝶閥結(jié)構(gòu)簡單、體積小、重量輕，只由少數(shù)幾個(gè)零件組成。而且只需旋轉(zhuǎn)90°即可快速啟閉，操作簡單，同時(shí)該閥門具有良好的流體控制特性。蝶閥處于完全開啟位置時(shí)，蝶板厚度是介質(zhì)流經(jīng)閥體時(shí)較少的阻力，因此通過該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。蝶閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊。</p><p style="text-indent:25px">幾種常用管道閥門的安裝：一.閘閥又稱閘板閥，是利用閘板來控制啟閉的閥門，通過改變橫斷面來調(diào)節(jié)管路流量和啟閉管路。閘閥多用于對流體介質(zhì)做全啟或全閉操作的管路。閘閥安裝一般無方向性要求，但不能倒裝。二.截止閥是利用閥瓣來控制啟閉的閥門。通過改變閥瓣與閥座的間隙，即改變通道截面的大小來調(diào)節(jié)介質(zhì)流量或截?cái)嘟橘|(zhì)通路。安裝截止閥必須注意流體的流向。安裝截止閥必須遵守的原則是，管道中的流體由下而上通過閥孔，俗稱“低進(jìn)高出”，不許裝反。閥門打壓試驗(yàn)后，密封腔閥腔內(nèi)氣體和水分因環(huán)境溫度升高而升壓。</p><div
