一、貝爾廠家直銷DQW一體化閥門電動裝置概述

部分回轉閥(fa)(fa)門電動裝(zhuang)(zhuang)置，簡稱為Q型(xing)電裝(zhuang)(zhuang)。是閥(fa)(fa)門實現開(kai)啟(qi)、關閉或調節控制的(de)驅動設備(bei)，適用于蝶閥(fa)(fa)、球閥(fa)(fa)、旋塞閥(fa)(fa)和(he)風(feng)門等(deng)做90°回轉的(de)閥(fa)(fa)門。本(ben)系列(lie)電動裝(zhuang)(zhuang)置可遠(yuan)距離控制，也可現場(chang)操作。廣泛用于電力、冶(ye)金、石(shi)油、化工、食品、紡織(zhi)、造紙、制藥、水廠和(he)污水處(chu)理等(deng)行業。

   本產品的(de)性能符合JB/T8528-1997《普通型(xing)閥門電動裝置(zhi)技術(shu)條件》的(de)規(gui)(gui)定；隔爆(bao)型(xing)的(de)性能符合GB3836.1-2000《爆(bao)炸性氣(qi)體環(huan)境用電氣(qi)設(she)備(bei)第(di)1部分(fen)(fen)：通用要求》，GB3836.2-2000《爆(bao)炸性氣(qi)體環(huan)境用電氣(qi)設(she)備(bei)第(di)2部分(fen)(fen)：隔爆(bao)型(xing)“d"》及JB/T8529-1997《隔爆(bao)型(xing)閥門電動裝置(zhi)技術(shu)條件》的(de)規(gui)(gui)定。

部分(fen)回轉電(dian)動裝置(zhi)按防護類型可分(fen)為戶外型和隔爆型；

按控制(zhi)方(fang)式又可分為常(chang)規型、整體型和整體調節型。

三、結構(gou)

   Q型電動裝置由電機(ji)、減速(su)機(ji)構(gou)、行程控制機(ji)構(gou)、力矩(ju)控制機(ji)構(gou)、開(kai)度指示機(ji)構(gou)、手(shou)輪、機(ji)械(xie)限(xian)位和電氣部分等組成。

注意：隔(ge)(ge)爆(bao)(bao)(bao)型(xing)(xing)電(dian)(dian)(dian)氣(qi)部分增加了(le)隔(ge)(ge)爆(bao)(bao)(bao)面結(jie)構，并采用(yong)隔(ge)(ge)爆(bao)(bao)(bao)型(xing)(xing)接線盒和隔(ge)(ge)爆(bao)(bao)(bao)型(xing)(xing)閥門(men)用(yong)電(dian)(dian)(dian)動機。安裝、調試和維護時(shi)，不可損傷隔(ge)(ge)爆(bao)(bao)(bao)面；不得(de)在爆(bao)(bao)(bao)炸(zha)環(huan)境下拆去與電(dian)(dian)(dian)氣(qi)有(you)關的箱(xiang)蓋帶電(dian)(dian)(dian)操(cao)作，打開(kai)電(dian)(dian)(dian)氣(qi)箱(xiang)蓋前必須先切斷電(dian)(dian)(dian)源；重(zhong)裝時(shi)蓋嚴緊固以(yi)保證隔(ge)(ge)爆(bao)(bao)(bao)性能！                                                                  

電動機：戶外型(xing)采用YDFf型(xing)，隔(ge)爆型(xing)采用YBDFf型(xing)閥門異步電動機。

減速(su)機構：由一對直齒(chi)輪和少(shao)齒(chi)差行星輪兩級傳動(dong)(dong)組(zu)成。電動(dong)(dong)機的動(dong)(dong)力(li)經(jing)減速(su)機構傳遞給輸出盤(pan)。

力矩(ju)控制機(ji)構：當(dang)輸出軸(zhou)(zhou)上(shang)受到(dao)(dao)一定(ding)轉(zhuan)(zhuan)矩(ju)后，蝸桿(gan)除旋轉(zhuan)(zhuan)外(wai)還產(chan)生軸(zhou)(zhou)向位移(yi)，由(you)蝸桿(gan)上(shang)的(de)齒(chi)條帶動(dong)(dong)(dong)齒(chi)軸(zhou)(zhou)轉(zhuan)(zhuan)動(dong)(dong)(dong)，當(dang)輸出力矩(ju)增大到(dao)(dao)整定(ding)轉(zhuan)(zhuan)矩(ju)時，則緊(jin)固在齒(chi)軸(zhou)(zhou)上(shang)的(de)凸(tu)輪(lun)使微動(dong)(dong)(dong)開關動(dong)(dong)(dong)作，從而(er)切斷(duan)電(dian)(dian)動(dong)(dong)(dong)機(ji)電(dian)(dian)源(yuan)，電(dian)(dian)動(dong)(dong)(dong)機(ji)停轉(zhuan)(zhuan)，以此實現(xian)對電(dian)(dian)動(dong)(dong)(dong)裝置輸出轉(zhuan)(zhuan)矩(ju)的(de)控制，達到(dao)(dao)保護閥門(men)的(de)目(mu)的(de)。

行(xing)程控制(zhi)機(ji)(ji)構：凸輪(lun)軸(zhou)與輸出盤同步轉動(dong)(dong)(dong)(dong)，當凸輪(lun)軸(zhou)轉至預先設定(ding)的(de)行(xing)程位置時(shi)，緊(jin)固在凸輪(lun)軸(zhou)上的(de)凸輪(lun)使微動(dong)(dong)(dong)(dong)開關動(dong)(dong)(dong)(dong)作，切斷(duan)電動(dong)(dong)(dong)(dong)機(ji)(ji)電源，從而實現對(dui)電動(dong)(dong)(dong)(dong)裝置行(xing)程的(de)控制(zhi)。

開(kai)(kai)度(du)指(zhi)(zhi)(zhi)示(shi)機構：開(kai)(kai)度(du)指(zhi)(zhi)(zhi)示(shi)盤固定于行程開(kai)(kai)關上(shang)，凸輪軸轉(zhuan)(zhuan)動(dong)使指(zhi)(zhi)(zhi)針同(tong)時(shi)轉(zhuan)(zhuan)動(dong)，以指(zhi)(zhi)(zhi)示(shi)閥門(men)的開(kai)(kai)關量，同(tong)時(shi)，凸輪軸上(shang)的開(kai)(kai)度(du)齒輪通過蹭(ceng)齒輪帶動(dong)電(dian)位器齒輪，電(dian)位器軸轉(zhuan)(zhuan)動(dong)，供遠傳開(kai)(kai)度(du)指(zhi)(zhi)(zhi)示(shi)用。

手-電(dian)動(dong)(dong)切換：全(quan)自(zi)動(dong)(dong)切換，需手動(dong)(dong)時(shi)直(zhi)接(jie)轉動(dong)(dong)手輪(lun)即可操作(zuo)電(dian)動(dong)(dong)裝(zhuang)置；需電(dian)動(dong)(dong)時(shi)直(zhi)接(jie)電(dian)動(dong)(dong)操作(zuo)，沒有切換手柄的
