style="font-size:16px;">閘閥的特點(diǎn)和用途：閘閥的優(yōu)點(diǎn)是流動(dòng)阻力小，開(kāi)閉較省力，不受介質(zhì)流向的限制，介質(zhì)可以兩個(gè)方向流動(dòng)，結(jié)構(gòu)尺寸較小，全開(kāi)時(shí)密封面受介質(zhì)沖蝕小。缺點(diǎn)是結(jié)構(gòu)復(fù)雜，高度尺寸較大，開(kāi)啟需一定的空間，開(kāi)閉時(shí)間長(zhǎng)，開(kāi)閉時(shí)密封面容易受沖蝕和擦傷。閘閥的應(yīng)用范圍是由其特點(diǎn)決定的，一般用于公稱通徑大于100mm的管道上，作切斷作用。閘閥可依靠介質(zhì)壓力緊緊與密封面緊閉，從而達(dá)到不泄露的效果。當(dāng)啟閉時(shí)閥芯和閥座密封面始終接觸并相互磨擦，因此密封面容易磨損，閘閥處于接近關(guān)閉時(shí)，管道前后壓差很大，使密封面磨損更加嚴(yán)重。閘閥的結(jié)構(gòu)會(huì)比截止閥更復(fù)雜，從外形來(lái)看，同口徑情況下，閘閥要比截止閥高，截止閥要比閘閥長(zhǎng)。另外，閘閥還有明桿和暗桿之分。截止閥沒(méi)有。</span>
