style="text-indent:25px">分溢流閥、減壓閥、順序閥這三種閥都是壓力控制閥，他們的工作原理基本相同，都是以壓力油的控制壓力來使閥口啟閉。不同點的是減壓閥主要是用來降低液壓系統(tǒng)某一分支油路的壓力，使分支壓力比主油路壓力低且穩(wěn)定，在調(diào)定壓力的范圍內(nèi)，減壓閥也像溢流閥那樣是關(guān)閉的。但是隨著系統(tǒng)壓力的升高當(dāng)達(dá)到減壓閥調(diào)定的壓力時，減壓閥打開，部分油液會經(jīng)過他返回油箱（此時有一定壓力的油回油箱，油箱的油溫會上升），NORGREN比例閥，NORGREN比例閥，這一支路的油壓是不會上升了。減壓閥起到對本支路的減壓與穩(wěn)壓作用。溢流閥則不同，NORGREN比例閥，它裝在泵的出口處會保證系統(tǒng)的整體壓力穩(wěn)定且不會超壓?？梢哉f溢流閥是被動工作，而減壓閥是主動工作。不同的閥門有什么不同的優(yōu)點？NORGREN比例閥</p><div

1800年，古埃及人為了防止尼羅河泛濫而修建大規(guī)模水利時，也曾運用過類似的木制旋塞來控制水流的分配。這些都是閥門的雛形。工業(yè)用閥門的大量應(yīng)用，是從瓦特發(fā)明蒸汽機(jī)以后才開始的。二十世紀(jì)初出現(xiàn)了鑄鐵、鑄鋼、鍛鋼、不銹鋼、鉻鉬鋼、黃銅等各種材質(zhì)的閥門。應(yīng)用于各個行業(yè)，各種工況。國內(nèi)比較早引進(jìn)國外閥門生產(chǎn)技術(shù)的公司不多，后引進(jìn)國外生產(chǎn)技術(shù)，使得國內(nèi)閥門生產(chǎn)技術(shù)的突破，質(zhì)量的提高，使用期限的加長。

1.密封型蝶閥這種蝶閥在關(guān)閉時能夠保證完全密封,在管道上可以作為切斷用,密封圈通常采用橡膠或塑料制成。但是,目前國內(nèi)也有采用金屬材料制成的密封圈,稱為雙偏心或三偏心蝶閥,也能保證良好的密封性能。 2.非密封型蝶閥這種蝶閥在關(guān)閉狀態(tài)時不能保證完全密封,在管道上只能作為節(jié)流用。其密封副材料通常采用的是金屬。作為流量控制用的蝶閥,大多采用金屬密封副。蝶閥和管道連接的方式有對夾式、雙法蘭式和單法蘭式三種,但較為常用的是對夾式和雙法蘭式。對夾式是用雙頭螺栓將閥門連接在管道上的兩法蘭之間。閥體形式可以為單法蘭式、無法蘭式或U形截面式。</p><p style="text-indent:25px">閥門安裝需要注意哪些事項呢? 1、安裝閥門時需要清潔內(nèi)腔和密封面,連接螺栓是否均勻擰緊,檢查填料是否壓緊。 2、安裝時的閥門是處于關(guān)閉狀態(tài)。大規(guī)格的閘閥、氣動調(diào)節(jié)閥應(yīng)該豎裝，以免因閥芯的自重較大而偏向一方，這樣會產(chǎn)生泄露情況。 3、閥門應(yīng)按照允許的工作位置安裝,但須注意檢修和操作的方便。 4、截止閥的安裝應(yīng)使介質(zhì)流向與閥體上標(biāo)示的箭頭一致，對不經(jīng)常啟閉而又需要嚴(yán)格保證在關(guān)閉狀態(tài)下不漏的閥門，可以反裝，以借助介質(zhì)壓力使之緊閉。 5、在擰緊壓緊螺釘時，閥門應(yīng)處于微開狀態(tài)，以免壓壞閥頂密封面。 6、低溫閥門在定位之前應(yīng)盡量在冷態(tài)下做啟閉試驗，要求靈活無卡殼現(xiàn)象。 7、液體閥應(yīng)配置成閥桿與水平成10°傾斜角，避免液體順著閥桿流出，更嚴(yán)重的是避免產(chǎn)生泄露。 8、嚴(yán)禁在安裝時把閥桿當(dāng)腳手架攀登。 9、所有閥門就位后，應(yīng)再作一次啟閉，靈活無卡住現(xiàn)象為合格。 10、閥門安裝之前，要確認(rèn)閥門符合設(shè)計要求和有關(guān)標(biāo)準(zhǔn)。管道內(nèi)部要清洗，除去鐵屑等雜質(zhì)，防止閥門密封座夾雜異物。 11、高溫閥門安裝時處于常溫，使用后，溫度升高，螺栓受熱膨脹，間隙加大，所以需要再次擰緊，這個問題需注意，不然容易發(fā)生泄露。閥門的維護(hù)方法有哪些？</p><div
