耐磨陶瓷止回閥
工作原理:
陶瓷(ci)止(zhi)(zhi)回(hui)閥(fa)(fa),啟閉件靠(kao)介(jie)質(zhi)流動(dong)(dong)和(he)力(li)(li)量自(zi)(zi)行(xing)開啟或關(guan)閉,以(yi)防止(zhi)(zhi)介(jie)質(zhi)倒流,驅動(dong)(dong)方(fang)式(shi)可(ke)選(xuan)用(yong)自(zi)(zi)動(dong)(dong)和(he)氣動(dong)(dong),連接方(fang)式(shi)可(ke)選(xuan)用(yong)法(fa)蘭或焊接,結構形(xing)式(shi)可(ke)選(xuan)用(yong)旋啟式(shi),密(mi)封(feng)結構可(ke)選(xuan)用(yong)軟密(mi)封(feng)、硬密(mi)封(feng)。該產(chan)品主(zhu)(zhu)要針對火力(li)(li)發電廠(chang)灰渣排(pai)放系(xi)統(tong)設計。閥(fa)(fa)瓣(ban)在(zai)閥(fa)(fa)體內(nei)腔處于自(zi)(zi)然(ran)下垂狀態,當開泵正常運(yun)行(xing)時,管路(lu)內(nei)的壓力(li)(li)將閥(fa)(fa)瓣(ban)推(tui)動(dong)(dong)沿閥(fa)(fa)桿軸(zhou)線(xian)轉動(dong)(dong)而開啟,介(jie)質(zhi)通過;停泵時,閥(fa)(fa)瓣(ban)以(yi)自(zi)(zi)身(shen)重(zhong)力(li)(li)和(he)介(jie)質(zhi)回(hui)流的壓力(li)(li)而自(zi)(zi)動(dong)(dong)關(guan)閉實現止(zhi)(zhi)回(hui),防止(zhi)(zhi)介(jie)質(zhi)倒流。它屬于自(zi)(zi)動(dong)(dong)閥(fa)(fa)類,主(zhu)(zhu)要用(yong)于介(jie)質(zhi)單向(xiang)(xiang)流動(dong)(dong)的管道上,只允許介(jie)質(zhi)向(xiang)(xiang)一個(ge)方(fang)向(xiang)(xiang)流動(dong)(dong),以(yi)防止(zhi)(zhi)發生事故。

優勢:
1.所有(you)與介(jie)質接觸的部分均為結(jie)構陶瓷材料,其(qi)化學穩定性及硬度(du)*(洛氏硬度(du)HRC90),僅(jin)次于金剛石;
2.陶(tao)瓷良好(hao)的耐(nai)磨(mo)性(xing),讓本閥經久耐(nai)用(yong),可靠性(xing)*,使用(yong)壽命長(chang),是(shi)鈦合金閥和蒙(meng)乃爾閥的2-4倍;
3.本閥具有*的耐(nai)磨損、耐(nai)腐蝕(shi)(shi)、耐(nai)沖蝕(shi)(shi)性能且(qie)隔熱(re)性好;
4.可用于高硬(ying)度的顆粒(li)介(jie)質;可用于各(ge)種復雜工況,更專(zhuan)業!
5.可用(yong)于有軟顆粒但(dan)又(you)有腐蝕(shi)介(jie)質(zhi)中;成本(ben)低,使用(yong)壽命長,性價比高(gao);
6.針對上述介質(zhi),本(ben)閥(fa)門具有*的(de)優勢,也(ye)是目前*合適(shi)此類介質(zhi)閥(fa)門。
陶(tao)瓷止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)按(an)結構劃分,也(ye)可(ke)(ke)分為(wei)(wei)升降(jiang)(jiang)式(shi)(shi)(shi)(shi)止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)、旋(xuan)啟式(shi)(shi)(shi)(shi)止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)和蝶(die)式(shi)(shi)(shi)(shi)止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)三種(zhong)(zhong)。升降(jiang)(jiang)式(shi)(shi)(shi)(shi)止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)可(ke)(ke)分為(wei)(wei)立式(shi)(shi)(shi)(shi)和直通式(shi)(shi)(shi)(shi)兩種(zhong)(zhong)。旋(xuan)啟式(shi)(shi)(shi)(shi)止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)分為(wei)(wei)單瓣(ban)式(shi)(shi)(shi)(shi)、雙瓣(ban)式(shi)(shi)(shi)(shi)和多瓣(ban)式(shi)(shi)(shi)(shi)三種(zhong)(zhong)。蝶(die)式(shi)(shi)(shi)(shi)止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)為(wei)(wei)碟式(shi)(shi)(shi)(shi)雙瓣(ban)、碟式(shi)(shi)(shi)(shi)單瓣(ban)、以(yi)上幾種(zhong)(zhong)止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)在連(lian)接(jie)形式(shi)(shi)(shi)(shi)上可(ke)(ke)分為(wei)(wei)螺(luo)紋(wen)連(lian)接(jie)、法蘭(lan)連(lian)接(jie)、焊(han)接(jie)和對夾式(shi)(shi)(shi)(shi)連(lian)接(jie)四種(zhong)(zhong)。
