D673H氣動硬密封對夾式蝶閥

產品簡介：

D673H氣動硬密封對夾蝶閥D673H-16C氣動硬密封蝶閥D673H-25C氣動金屬硬密封蝶閥D673Y氣動硬質合金密封對夾式蝶閥/D673W氣動硬密封不銹鋼蝶閥/氣動三偏心蝶閥/氣動三偏心硬密封蝶閥/氣動多層次金屬硬密封蝶閥/氣動對夾式蝶閥/氣動硬密封開關蝶閥/氣動硬密封切斷蝶閥D673H氣動蝶閥采用(yong)三維(wei)偏心(xin)結構，蝶板為軟硬(ying)層疊(die)式金(jin)屬片，具有金(jin)屬硬(ying)密(mi)封和彈性(xing)密(mi)封的(de)雙重(zhong)優點(dian)。硬(ying)密(mi)封蝶閥具有雙向(xiang)密(mi)封功能，安裝時不受(shou)(shou)介質(zhi)流(liu)向(xiang)的(de)限制，也不受(shou)(shou)空間位置的(de)影響，可在(zai)任(ren)何方(fang)向(xiang)安裝。硬(ying)密(mi)封蝶閥被廣(guang)泛(fan)用(yong)于(yu)介質(zhi)溫度(du)≤425℃的(de)冶(ye)金(jin)、電(dian)力、石油、化工等工業管(guan)道上，做調節流(liu)量和截斷(duan)流(liu)體使用(yong)。

產品特點：

1、硬密(mi)封氣動蝶(die)閥采用金(jin)屬密(mi)封可(ke)適(shi)用于帶稍許(xu)顆粒、漿液(ye)的介質中

2、硬密封(feng)氣動蝶閥(fa)適用溫度可達425℃

3、密封(feng)時幾(ji)乎無摩(mo)擦，保證扭(niu)矩(ju)更(geng)小，密封(feng)性更(geng)好

氣動執行器：

采用(yong)新型ATD系列(lie)氣(qi)動執(zhi)行器，有(you)雙(shuang)作(zuo)用(yong)式和單作(zuo)用(yong)式（彈(dan)簧復位(wei)），齒(chi)輪傳動，安(an)全可靠。

1、齒輪式雙活(huo)塞，輸出(chu)力矩(ju)大，體(ti)積(ji)小。

2、氣缸選用鋁(lv)金材料，重量輕、外(wai)形美觀(guan)。

3、可在頂部、底(di)部安裝手動操作(zuo)機構。

4、齒條式連接可調節開啟角度、額定流量(liang)。

5、執(zhi)行(xing)器可選帶電訊(xun)號反饋指(zhi)示及(ji)各類附件(jian)以實現自動化操作。

7、兩端調(diao)的節螺釘可使標準產品在0°和90°有(you)±4°的可調(diao)范圍，確保與閥門的同(tong)步精(jing)度。

單作用氣動執行器和雙作用氣動執行器的區別：

氣(qi)動(dong)球閥中單作(zuo)用(yong)(yong)和雙(shuang)作(zuo)用(yong)(yong)指的(de)是氣(qi)動(dong)球閥所配氣(qi)動(dong)執(zhi)行(xing)器可分(fen)為單作(zuo)用(yong)(yong)和雙(shuang)作(zuo)用(yong)(yong)。其區別在(zai)于(yu)：單作(zuo)用(yong)(yong)的(de)氣(qi)缸內(nei)有彈簧，而雙(shuang)作(zuo)用(yong)(yong)內(nei)沒有。因此單作(zuo)用(yong)(yong)氣(qi)動(dong)執(zhi)行(xing)器的(de)價格比雙(shuang)作(zuo)用(yong)(yong)氣(qi)動(dong)執(zhi)行(xing)器的(de)價格要(yao)高。

單作用(yong)氣(qi)(qi)(qi)動(dong)執(zhi)(zhi)(zhi)行器(qi)一般分(fen)為(wei)常開(kai)(kai)(kai)型(xing)和常閉(bi)型(xing)（常開(kai)(kai)(kai)型(xing)：通(tong)氣(qi)(qi)(qi)關(guan)，斷氣(qi)(qi)(qi)開(kai)(kai)(kai)；常閉(bi)型(xing)：通(tong)氣(qi)(qi)(qi)開(kai)(kai)(kai)，斷氣(qi)(qi)(qi)關(guan)），也就(jiu)是(shi)說(shuo)，在(zai)(zai)安裝之(zhi)前有(you)一個設定(ding)，設定(ding)其為(wei)開(kai)(kai)(kai)或者(zhe)關(guan)，如果是(shi)常開(kai)(kai)(kai)的(de)，那就(jiu)是(shi)在(zai)(zai)通(tong)氣(qi)(qi)(qi)的(de)情況(kuang)(kuang)下氣(qi)(qi)(qi)動(dong)執(zhi)(zhi)(zhi)行器(qi)關(guan)閉(bi)閥門，如果氣(qi)(qi)(qi)源出現(xian)故(gu)障(zhang)或者(zhe)突(tu)然停電(dian)，單作用(yong)氣(qi)(qi)(qi)動(dong)執(zhi)(zhi)(zhi)行器(qi)靠彈簧自(zi)動(dong)復(fu)位為(wei)開(kai)(kai)(kai)的(de)狀態，也就(jiu)是(shi)說(shuo)會(hui)回(hui)到它的(de)設定(ding)狀態，設定(ding)為(wei)關(guan)，則會(hui)回(hui)到關(guan)的(de)狀態，一般在(zai)(zai)危(wei)(wei)險(xian)的(de)工(gong)況(kuang)(kuang)中(zhong)使用(yong)較多，比如輸送可(ke)燃(ran)氣(qi)(qi)(qi)體或可(ke)燃(ran)液體，在(zai)(zai)失去氣(qi)(qi)(qi)源又出現(xian)緊急情況(kuang)(kuang)的(de)時(shi)候，單作用(yong)氣(qi)(qi)(qi)動(dong)執(zhi)(zhi)(zhi)行機(ji)構能(neng)自(zi)動(dong)復(fu)位把危(wei)(wei)險(xian)降低，而雙(shuang)作用(yong)就(jiu)不(bu)能(neng)復(fu)位。

雙(shuang)作(zuo)用氣(qi)動(dong)執(zhi)行(xing)器(qi)在通(tong)氣(qi)的情況(kuang)下(xia)氣(qi)動(dong)執(zhi)行(xing)器(qi)打開閥門，當要(yao)關(guan)閉閥門的時候另外一邊通(tong)氣(qi)才(cai)能關(guan)閉，雙(shuang)作(zuo)用氣(qi)動(dong)執(zhi)行(xing)器(qi)是(shi)靠氣(qi)缸工(gong)作(zuo)復位(wei)的，在失去氣(qi)源(yuan)的時候只能保持(chi)原位(wei)。

單電控電磁閥和雙電控電磁閥的區別：

單電控：即只有一個電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)圈(quan)，一般(ban)用(yong)在2位(wei)3通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)，線(xian)(xian)圈(quan)電(dian)(dian)(dian)(dian)(dian)(dian)壓等(deng)級一般(ban)采用(yong)DC24V、AC220V等(deng)。 兩位(wei)三(san)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)分為(wei)常閉(bi)型(xing)(xing)(xing)和常開(kai)(kai)(kai)型(xing)(xing)(xing)兩種，常閉(bi)型(xing)(xing)(xing)指線(xian)(xian)圈(quan)沒(mei)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)時氣路是斷(duan)的，常開(kai)(kai)(kai)型(xing)(xing)(xing)指線(xian)(xian)圈(quan)沒(mei)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)時氣路是通(tong)(tong)(tong)的。 常閉(bi)型(xing)(xing)(xing)兩位(wei)三(san)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)動作原理(li)(li)：給(gei)線(xian)(xian)圈(quan)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)，氣路接(jie)通(tong)(tong)(tong)，線(xian)(xian)圈(quan)一旦(dan)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)，氣路就(jiu)會斷(duan)開(kai)(kai)(kai)，這相(xiang)當于“點動"。 常開(kai)(kai)(kai)型(xing)(xing)(xing)兩位(wei)三(san)通(tong)(tong)(tong)單電(dian)(dian)(dian)(dian)(dian)(dian)控(kong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)動作原理(li)(li)：給(gei)線(xian)(xian)圈(quan)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)(dian)(dian)，氣路斷(duan)開(kai)(kai)(kai)，線(xian)(xian)圈(quan)一旦(dan)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)，氣路就(jiu)會接(jie)通(tong)(tong)(tong)，這也是“點動"。

雙電控：即(ji)有(you)兩個電(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)圈(quan)(quan)，一般(ban)用(yong)在(zai)兩位五通(tong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)，兩位五通(tong)雙(shuang)電(dian)(dian)(dian)控(kong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)動(dong)(dong)作原理：給(gei)(gei)(gei)正(zheng)(zheng)動(dong)(dong)作線(xian)(xian)圈(quan)(quan)通(tong)電(dian)(dian)(dian)，則正(zheng)(zheng)動(dong)(dong)作氣路接通(tong)(正(zheng)(zheng)動(dong)(dong)作出(chu)(chu)氣孔有(you)氣)，即(ji)使(shi)給(gei)(gei)(gei)正(zheng)(zheng)動(dong)(dong)作線(xian)(xian)圈(quan)(quan)斷電(dian)(dian)(dian)后(hou)正(zheng)(zheng)動(dong)(dong)作氣路仍(reng)然是接通(tong)的(de)，將會一直維持(chi)到給(gei)(gei)(gei)反動(dong)(dong)作線(xian)(xian)圈(quan)(quan)通(tong)電(dian)(dian)(dian)為(wei)止(zhi)。 給(gei)(gei)(gei)反動(dong)(dong)作線(xian)(xian)圈(quan)(quan)通(tong)電(dian)(dian)(dian)，則反動(dong)(dong)作氣路接通(tong)(反動(dong)(dong)作出(chu)(chu)氣孔有(you)氣)，即(ji)使(shi)給(gei)(gei)(gei)反動(dong)(dong)作線(xian)(xian)圈(quan)(quan)斷電(dian)(dian)(dian)后(hou)反動(dong)(dong)作氣路仍(reng)然是接通(tong)的(de)，將會一直維持(chi)到給(gei)(gei)(gei)正(zheng)(zheng)動(dong)(dong)作線(xian)(xian)圈(quan)(quan)通(tong)電(dian)(dian)(dian)為(wei)止(zhi)。這(zhe)相當于“自(zi)鎖"。 基于兩位五通(tong)雙(shuang)電(dian)(dian)(dian)控(kong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)的(de)這(zhe)種特性(xing)，在(zai)設計機電(dian)(dian)(dian)控(kong)制(zhi)(zhi)回路或編制(zhi)(zhi)PLC程序的(de)時候，可以讓電(dian)(dian)(dian)磁(ci)(ci)閥(fa)線(xian)(xian)圈(quan)(quan)動(dong)(dong)作1~2秒就可以了，這(zhe)樣可以保護(hu)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)線(xian)(xian)圈(quan)(quan)不(bu)容易損壞。
