1.密封型蝶閥這種蝶閥在關(guān)閉時(shí)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(guó)內(nèi)也有采用金屬材料制成的密封圈,稱(chēng)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(shí)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(duì)夾式、雙法蘭式和單法蘭式三種,但較為常用的是對(duì)夾式和雙法蘭式。對(duì)夾式是用雙頭螺栓將閥門(mén)連接在管道上的兩法蘭之間。閥體形式可以為單法蘭式、無(wú)法蘭式或U形截面式。角座閥閥門(mén)該如何去維護(hù)它呢？</p><div

1、重量輕：本體采用高質(zhì)量球黑鑄鐵制成，重量較傳統(tǒng)閘閥重量減輕約 20%~30%，安裝維修方便。 2、整體包膠：閘板采用***的橡膠進(jìn)行整體內(nèi)、外包膠，歐洲橡膠硫化技術(shù)使得硫化后的閘板能夠保證精確的幾何尺寸，且橡膠與球墨鑄閘板接著牢靠，不易脫落及彈性記憶佳。 3、平底式閘座：傳統(tǒng)的閘閥往往在通水洗管后即因外物諸如石頭，木塊、水泥、鐵屑、雜物等淤積于閥底凹槽內(nèi)，容易造成無(wú)法關(guān)閉緊密而形成漏水現(xiàn)象，彈性座封閘閥底部采用與水管機(jī)同的平底設(shè)計(jì)，不易造成雜物淤積，使流體暢通無(wú)阻。 4、精鑄閥體：閥體采用精密鑄造，精確的幾何尺寸使得閥體內(nèi)部無(wú)需任何精加工即可保證閥門(mén)的密封性。華德溢流閥價(jià)格</p><p
