美國(guó)威迪/VETI品牌進(jìn)口凸耳式軟密封蝶閥通常安裝在管路末端做末端閥，由于其穩(wěn)定的連接性，也常用于熱變化頻繁的管路上起截?cái)嗪驼{(diào)節(jié)作用。
進(jìn)口凸耳式軟密封蝶閥產(chǎn)品結(jié)構(gòu)
閥桿：采用高強(qiáng)度單桿設(shè)計(jì)，閥桿與閥板的連接釆用雙偏精密咬合設(shè)計(jì)，無需螺絲和銷釘，避免與管線內(nèi)的流體接觸，防止泄露及腐蝕，而且拆卸上只需把閥桿從閥板拔出，安裝及維修方便
閥座：采用舌槽接合式閥座設(shè)計(jì)，能夠把閥體與管內(nèi)介質(zhì)隔離，具有更低的扭拒，閥座密封面有凸起O型環(huán),無需在安裝時(shí)另加法蘭墊片
閥桿保持圓環(huán):保持圓環(huán)把閥桿固定在閥體內(nèi)一個(gè)推墊圈和“C”型墊片，用專用小工具就可拆卸，可防止閥桿無意拔出
閥桿套：四氟軸套，抗腐蝕，阻尼小，抗壓能力強(qiáng)
密封圈：自調(diào)式雙“U”環(huán)形設(shè)計(jì)的密封圈保證雙向零泄露,并防止異物進(jìn)入閥桿腔內(nèi)
閥板:鑄件邊緣經(jīng)過球面加工和手工拋光,使用壽命長(zhǎng),操作扭矩低,氣泡密封雙向零泄露。
