閥門(mén)型號(hào)通常應(yīng)表示出閥門(mén)類(lèi)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(chēng)壓力等元素。閥門(mén)型號(hào)的標(biāo)準(zhǔn)化對(duì)閥門(mén)的設(shè)計(jì)、選用、銷(xiāo)售提供了方便。當(dāng)今閥門(mén)的類(lèi)型和材料越來(lái)越多，閥門(mén)的型號(hào)編制也愈來(lái)愈復(fù)雜。中國(guó)雖有閥門(mén)型號(hào)編制的統(tǒng)一標(biāo)準(zhǔn)，但愈來(lái)愈不能適應(yīng)閥門(mén)工業(yè)發(fā)展的需要。目前，國(guó)內(nèi)閥門(mén)制造廠通常采用JB/T

style="text-indent:25px">球閥按結(jié)構(gòu)形式可分為浮動(dòng)球球閥、固定球球閥、彈性球球閥； ①浮動(dòng)球球閥：球閥的球體是浮動(dòng)的，在介質(zhì)壓力作用下，球體能產(chǎn)生一定的位移并緊壓在出口端的密封面上，保證出口端密封。浮動(dòng)球球閥的結(jié)構(gòu)簡(jiǎn)單，密封性好，但球體承受工作介質(zhì)的載荷全部傳給了出口密封圈，因此要考慮密封圈材料能否經(jīng)受得住球體介質(zhì)的工作載荷。這種結(jié)構(gòu)，大范圍用于中低壓球閥。 ②固定球球閥:球閥的球體是固定的，受壓后不產(chǎn)生移動(dòng)。固定球球閥都帶有浮動(dòng)閥座，受介質(zhì)壓力后，閥座產(chǎn)生移動(dòng)，使密封圈緊壓在球體上，以保證密封。通常在與球體的上、下軸上裝有軸承，操作扭距小，適用于高壓和大口徑的閥門(mén)。為了減少球閥的操作扭矩和增加密封的可靠程度，出現(xiàn)了油封球閥，密封面間壓注特制的潤(rùn)滑油，以形成一層油膜，即增強(qiáng)了密封性，又減少了操作扭矩，更適用高壓大口徑的球閥。 ③彈性球球閥:球體和閥座密封圈都采用金屬材料制造，密封比壓很大，依靠介質(zhì)本身的壓力已達(dá)不到密封的要求，必須施加外力。這種閥門(mén)適用于高溫高壓介質(zhì)。彈性球體是在球體內(nèi)壁的下端開(kāi)一條彈性槽，而獲得彈性。當(dāng)關(guān)閉通道時(shí)，用閥桿的楔形頭使球體漲開(kāi)與閥座壓緊達(dá)到密封。</p><p style="text-indent:25px">在眾多的閥門(mén)產(chǎn)品中，閘閥和蝶閥都是很是常用的閥門(mén)型號(hào)。然而，很多用戶在選型時(shí)因不知道閘閥和蝶閥的區(qū)別是什么，而不知道如何選擇這兩種閥門(mén)。其實(shí)吧，從定義上區(qū)分；閘閥是一種較為常見(jiàn)的啟閉閥，利用閘板(即啟閉件，在閘板中啟閉件稱(chēng)為閘板或閘門(mén)，閘座稱(chēng)為閘板座)來(lái)接通(全開(kāi))或截?cái)?全關(guān))管路中的介質(zhì)。它不允許作為截流用，使用中應(yīng)避免將閘板微量開(kāi)啟，因高速流動(dòng)的介質(zhì)的沖蝕會(huì)加速密封面的損壞。閘板在垂直于閘門(mén)座通道中心線的片面作為升降運(yùn)動(dòng)，像閘門(mén)一樣截?cái)喙苈分械慕橘|(zhì)，故稱(chēng)做閘閥。而蝶閥是指關(guān)閉件(閥瓣或蝶板)為圓盤(pán)，圍繞閥軸旋轉(zhuǎn)來(lái)達(dá)到開(kāi)啟與關(guān)閉的一種閥，在管道上主要起切斷和節(jié)流用。蝶閥啟閉件是一個(gè)圓盤(pán)形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的目的。蝶閥全開(kāi)到全關(guān)通常是小于90°，蝶閥和蝶桿本身沒(méi)有自鎖能力，為了蝶板的定位，要在閥桿上加裝蝸輪減速器。采用蝸輪減速器，不僅可以使蝶板具有自鎖能力，使蝶板停止在任意位置上，還能改善閥門(mén)的操作性能。閥門(mén)的結(jié)構(gòu)和工作原理是什么？</p><div

style="text-indent:25px">鍛鋼閥門(mén)是指關(guān)閉件（閘板）沿通路中線的垂直方向移動(dòng)的閥門(mén)。鍛鋼閥門(mén)是用精煉的鍛鋼制作的閘閥，主要用在火力電站各種系統(tǒng)的管路上，可以控制空氣、水、蒸汽、油、液態(tài)金屬和放射介質(zhì)等流體的流動(dòng)。鍛鋼閥門(mén)相比較其它的閥門(mén)有：耐高溫高壓，獨(dú)特的自密封設(shè)計(jì)，壓力越高，密封越可靠等特點(diǎn)。由于性能技術(shù)特性、工況的特殊使產(chǎn)品也形成了其他產(chǎn)品所替代不了的特點(diǎn)。鍛鋼閘閥是使用很廣的一種閥門(mén)，一般口徑DN≥500mm的切斷裝置都選用它，有時(shí)口徑很小的切斷裝置也選用閘閥。閘閥作為一種級(jí)別較低的閥門(mén)，比較常見(jiàn)。不同類(lèi)型的閥門(mén)用于不同的地方。日本小金井電磁閥</p><p
