閘閥和插板閥的優(yōu)缺點(diǎn)以及區(qū)別。閘閥一般用在沒(méi)有顆粒的液體管道上，防止對(duì)密封面造成損壞，或在蒸汽管道上，密封效果較好。插板閥是閘閥的一種，插板閥通常用有較大顆粒的液體管道上，或用在固體、粉體物料的管道上，一般情況下閘閥密封效果要好，插板閥密封效果差一些。插板閥我知道的常用在有較多雜質(zhì)的污水管道上，優(yōu)其是環(huán)保處理管道上。閘閥的優(yōu)點(diǎn)：1、流體阻力小,密封面受介質(zhì)的忡刷和侵蝕小。2、開(kāi)閉較省力。3、介質(zhì)流向不受限制,不擾流、不降低壓力。4、形體簡(jiǎn)單,結(jié)構(gòu)長(zhǎng)度短，制造工藝性好，適用范圍廣。閘閥的缺點(diǎn):1、密封面之間易引起沖蝕和擦傷，維修比較困難。2、外形尺寸較大，開(kāi)啟需要的空間，開(kāi)閉時(shí)間長(zhǎng)。3、結(jié)構(gòu)較復(fù)雜。插板閥從八十年代進(jìn)入我國(guó)。在不到二十年的時(shí)間里，其使用范圍從普通領(lǐng)域擴(kuò)展到了更為廣闊的各行各業(yè)。從礦山電廠的選煤、排矸、排渣。發(fā)展到了城市的污水處理，從一般的工業(yè)管道發(fā)展到了食品、衛(wèi)生、醫(yī)藥等專(zhuān)業(yè)管道系統(tǒng)。超薄型的刀閘閥以其體積小、流阻小、重量輕、易安裝、易拆卸等優(yōu)點(diǎn)徹底解決了普通閘閥、平板閘閥、球閥、截止閥、調(diào)節(jié)閥、蝶閥等類(lèi)閥門(mén)的流阻大、重量大、安裝難、占地面積大等的疑難問(wèn)題。
