產品概述
一、D341F襯氟蝶閥概述：
蝶閥是用隨閥桿一起轉動的蝶板作啟閉件,用以實現閥門的開啟、關閉與調節。
蝶(die)閥在管路中除了起(qi)節斷和截流用外，近年來已經把(ba)密封性能作為評價的主要指標，受(shou)到市(shi)場青睞。另外，蝶(die)閥還(huan)有體積小(xiao)、重量輕(qing)、結構簡單等優(you)點，與同參(can)數閘閥比較，平均(jun)減輕(qing)重量達30～50%，蝶(die)板(ban)旋轉(zhuan)90°即可實現啟(qi)、閉(bi)(bi)過程(cheng)，又由于轉(zhuan)軸兩(liang)側蝶(die)板(ban)受(shou)介(jie)質作用力近似相(xiang)等，轉(zhuan)矩相(xiang)反，因此啟(qi)閉(bi)(bi)力矩較小(xiao)。
二、D341F襯氟蝶閥結構特點：
1.中線蝶閥為整個蝶板與閥座在360°圓周內同心（中線）,具有雙向密封功能,壓力,流量可自由調節；
2.四級加載彈性密封，保證了閥門內、外的零泄漏；
a.軸頭、蝶板園周連接處的特殊過渡曲線與閥座的合理過盈；
b.軸頭端面采用彈性O型圈和軸肩處剛性墊圈、彈性橡膠墊組合；
c.軸的徑向采用O型圈與金屬墊的組合；
d.閥座鑲在有彈性條的閥體的槽內；
3.采用可調彈性彈子定位。定位準確，結構簡單。
