一、DZW-10 電動閥門執行裝置產品介紹

        DZW多(duo)回(hui)轉閥(fa)(fa)門(men)(men)電動裝(zhuang)置，簡稱為(wei)Z型電裝(zhuang)，是閥(fa)(fa)門(men)(men)實現開啟、關閉或調節控制的驅動設(she)備。Z型電裝(zhuang)適用(yong)(yong)于閘閥(fa)(fa)、截止(zhi)閥(fa)(fa)、隔膜閥(fa)(fa)、柱塞閥(fa)(fa)、節流閥(fa)(fa)、水閘門(men)(men)等。可用(yong)(yong)于明桿閥(fa)(fa)，也(ye)可用(yong)(yong)于暗(an)桿閥(fa)(fa)。

        本系(xi)列(lie)電裝(zhuang)具有功能全、性能可靠、控(kong)(kong)制(zhi)系(xi)統先(xian)進(jin)、體積小(xiao)、重(zhong)量輕、使用(yong)(yong)維護方(fang)便等(deng)特點。可對閥門實行遠控(kong)(kong)、集控(kong)(kong)和自動控(kong)(kong)制(zhi)。廣(guang)泛用(yong)(yong)于電力、冶金、石油、化工、造紙、污水處理等(deng)行業。

二、DZW-10 電動閥門執行裝置與閥門連接型式及(ji)尺寸(cun)

三、DZW-10 結構說明

        1、電動機：戶(hu)外型采用(yong)YDF型，隔爆型采用(yong)YBDF型閥門三相(xiang)異(yi)步電動機。

        2、減(jian)速機構(gou)：由一對直齒輪和蝸(gua)輪副(fu)兩(liang)級傳(chuan)動組成。電動機的動力(li)經減(jian)速機構(gou)傳(chuan)遞給輸出軸(zhou)。

        3、力(li)矩(ju)控制(zhi)機(ji)(ji)構：當輸(shu)(shu)出軸上受到一(yi)定轉(zhuan)矩(ju)后，蝸桿(gan)除旋(xuan)轉(zhuan)外還產(chan)生軸向位(wei)移，帶動(dong)曲(qu)拐，曲(qu)拐直接（或通(tong)過撞塊(kuai)）帶動(dong)支架產(chan)生角(jiao)位(wei)移。當輸(shu)(shu)出軸上的轉(zhuan)矩(ju)增大到整定轉(zhuan)矩(ju)時(shi)，則支架產(chan)生的位(wei)移量使微動(dong)開關動(dong)作，從而切斷電機(ji)(ji)電源，電動(dong)機(ji)(ji)停轉(zhuan)。以此實現(xian)對電動(dong)裝(zhuang)置(zhi)輸(shu)(shu)出轉(zhuan)矩(ju)的控制(zhi)，達(da)到保護電動(dong)閥門的目(mu)的。

        4、行(xing)程(cheng)(cheng)(cheng)控(kong)(kong)制(zhi)機構：采用(yong)十進(jin)制(zhi)計數(shu)(shu)器(qi)(qi)原(yuan)理(li)(li)，又稱為計數(shu)(shu)器(qi)(qi)，控(kong)(kong)制(zhi)精度高。其(qi)工作原(yuan)理(li)(li)為：由(you)減(jian)速(su)箱內(nei)的(de)一對大小傘(san)齒(chi)輪(lun)帶(dai)動(dong)(dong)中傳小齒(chi)輪(lun)，再帶(dai)動(dong)(dong)行(xing)程(cheng)(cheng)(cheng)控(kong)(kong)制(zhi)機構工作。如(ru)果行(xing)程(cheng)(cheng)(cheng)控(kong)(kong)制(zhi)器(qi)(qi)按閥門開(kai)、關的(de)位置(zhi)已(yi)調整好(hao)，當控(kong)(kong)制(zhi)器(qi)(qi)隨輸出(chu)軸(zhou)轉(zhuan)動(dong)(dong)到(dao)預先調整好(hao)的(de)位置(zhi)（圈數(shu)(shu)）時(shi)，則凸輪(lun)將(jiang)轉(zhuan)動(dong)(dong)90°，迫使(shi)微動(dong)(dong)開(kai)關動(dong)(dong)作，切(qie)斷電(dian)動(dong)(dong)機電(dian)源，電(dian)動(dong)(dong)機停(ting)轉(zhuan)，從而實現對電(dian)動(dong)(dong)裝置(zhi)行(xing)程(cheng)(cheng)(cheng)（轉(zhuan)圈數(shu)(shu)）的(de)控(kong)(kong)制(zhi)。

           注1：為了控制(zhi)較多轉圈數的閥門，可(ke)調整(zheng)凸輪轉180°或270°再(zai)壓迫微動(dong)開關動(dong)作。

        5、開度(du)指(zhi)示(shi)(shi)機構：輸(shu)入齒(chi)(chi)輪由計數(shu)器個位齒(chi)(chi)輪帶動，經減速后(hou)，指(zhi)示(shi)(shi)盤隨閥(fa)門的開關過程同(tong)時轉(zhuan)動，以指(zhi)示(shi)(shi)閥(fa)門的開關量，電位器軸(zhou)和指(zhi)示(shi)(shi)盤同(tong)步轉(zhuan)動，供遠傳開度(du)指(zhi)示(shi)(shi)用。移動轉(zhuan)圈(quan)數(shu)調整齒(chi)(chi)輪可以改變轉(zhuan)圈(quan)數(shu)。開度(du)指(zhi)示(shi)(shi)機構內設一微(wei)動開關和凸(tu)輪，當電動裝置運轉(zhuan)時，旋(xuan)轉(zhuan)凸(tu)輪周期性地使(shi)(shi)微(wei)動開關動作，其(qi)頻率為輸(shu)出軸(zhou)轉(zhuan)動一圈(quan)動作一次或(huo)二次，可供閃光信號(hao)等使(shi)(shi)用。

        6、手(shou)(shou)—電動(dong)(dong)(dong)(dong)(dong)切換(huan)(huan)(huan)(huan)(huan)機構：為半自動(dong)(dong)(dong)(dong)(dong)切換(huan)(huan)(huan)(huan)(huan)，手(shou)(shou)動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)需扳動(dong)(dong)(dong)(dong)(dong)手(shou)(shou)柄(bing)切換(huan)(huan)(huan)(huan)(huan)，手(shou)(shou)動(dong)(dong)(dong)(dong)(dong)狀(zhuang)(zhuang)態轉(zhuan)變(bian)為電動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)則自動(dong)(dong)(dong)(dong)(dong)運行。它由(you)手(shou)(shou)柄(bing)、切換(huan)(huan)(huan)(huan)(huan)件(jian)、直立(li)桿(gan)、離合(he)(he)器(qi)、壓簧(huang)等(deng)組成(cheng)。需手(shou)(shou)輪(lun)操作時(shi)(shi)，將(jiang)手(shou)(shou)柄(bing)向(xiang)(xiang)手(shou)(shou)動(dong)(dong)(dong)(dong)(dong)方向(xiang)(xiang)推動(dong)(dong)(dong)(dong)(dong)，切換(huan)(huan)(huan)(huan)(huan)件(jian)使離合(he)(he)器(qi)抬(tai)高，并壓迫壓簧(huang)。當手(shou)(shou)柄(bing)推到一定位置時(shi)(shi)，離合(he)(he)器(qi)即脫離蝸(gua)輪(lun)而(er)與手(shou)(shou)輪(lun)嚙合(he)(he)，同時(shi)(shi)直立(li)桿(gan)在(zai)扭簧(huang)作用(yong)下(xia)直立(li)于蝸(gua)輪(lun)端面(mian)(mian)，支撐住離合(he)(he)器(qi)不致(zhi)下(xia)落，切換(huan)(huan)(huan)(huan)(huan)完成(cheng)即可放(fang)開手(shou)(shou)柄(bing)，使用(yong)手(shou)(shou)輪(lun)進行操作。而(er)需電動(dong)(dong)(dong)(dong)(dong)操作時(shi)(shi)，電動(dong)(dong)(dong)(dong)(dong)機將(jiang)帶(dai)動(dong)(dong)(dong)(dong)(dong)蝸(gua)輪(lun)轉(zhuan)動(dong)(dong)(dong)(dong)(dong)，支承于蝸(gua)輪(lun)端面(mian)(mian)的(de)直立(li)桿(gan)即倒下(xia)，在(zai)壓簧(huang)作用(yong)下(xia)離合(he)(he)器(qi)迅速向(xiang)(xiang)蝸(gua)輪(lun)方向(xiang)(xiang)移(yi)動(dong)(dong)(dong)(dong)(dong)，并與蝸(gua)輪(lun)嚙合(he)(he)，同時(shi)(shi)與手(shou)(shou)輪(lun)脫開，自動(dong)(dong)(dong)(dong)(dong)實現手(shou)(shou)動(dong)(dong)(dong)(dong)(dong)到電動(dong)(dong)(dong)(dong)(dong)狀(zhuang)(zhuang)態的(de)轉(zhuan)換(huan)(huan)(huan)(huan)(huan)。

           注意：1.電(dian)動運(yun)行時切勿扳(ban)動切換手柄！

                2.切換(huan)時按(an)箭頭方向推(tui)（或拉(la)）動手柄，若推(tui)不到位時應邊轉動手輪邊推(tui)動手柄！
