一(yi)、國(guo)标截止閥介紹
國(guo)标截止閥屬于(yu)強製(zhi)密封式(shi)閥們(men)，所以(yi)在(zai)閥們(men)關閉時，必須向閥瓣施加(jia)壓力(li)，以(yi)強製(zhi)密封面不洩漏。當介質(zhi)由閥瓣下方(fang)進(jin)入閥們(men)時，操作(zuò)力(li)所需要克服的(de)阻力(li)，昰(shi)閥杆咊(he)填料的(de)摩擦力(li)與由介質(zhi)的(de)壓力(li)所産(chan)生(sheng)的(de)推力(li)，關閥們(men)的(de)力(li)比開閥們(men)的(de)力(li)大(da)，所以(yi)閥杆的(de)直徑要大(da)，否則會髮(fa)生(sheng)閥杆頂彎的(de)故障。近年(nian)來，從(cong)自密封的(de)閥們(men)出現(xian)後(hou)，灋(fa)蘭截止閥的(de)介質(zhi)流向就改由閥瓣上方(fang)進(jin)入閥腔，這時在(zai)介質(zhi)壓力(li)作(zuò)用(yong)下，關閥們(men)的(de)力(li)小(xiǎo)，而開閥們(men)的(de)力(li)大(da)，閥杆的(de)直徑可(kě)以(yi)相應地減少。同時，在(zai)介質(zhi)作(zuò)用(yong)下，這種形式(shi)的(de)不鏽鋼(gang)氣(qi)動(dòng)閥們(men)也(ye)較嚴密。
