電動推桿盲板閥的制作方法

本產品涉及的是一種隔斷閥，具體的說是電動推桿盲板閥，以下由球(qiu)一閥門(men)廠(chang)家介紹技術背景。

隨(sui)著高(gao)爐于(yu)法(fa)布(bu)(bu)袋(dai)除塵(chen)(chen)技術的(de)發展，對閥門的(de)綜(zong)合性能也提出(chu)了(le)更高(gao)的(de)要 求。煤(mei)(mei)氣(qi)(qi)操(cao)作(zuo)(zuo)An全第Yi，高(gao)爐布(bu)(bu)袋(dai)除塵(chen)(chen)系(xi)統中，對煤(mei)(mei)氣(qi)(qi)控制采用自控，遙控技 術，是高(gao)爐布(bu)(bu)袋(dai)除塵(chen)(chen)技術上一臺階(jie)的(de)標(biao)志。而當前高(gao)爐干法(fa)布(bu)(bu)袋(dai)除塵(chen)(chen)系(xi)統大多 數廠家仍采用手(shou)動式盲扳閥作(zuo)(zuo)為煤(mei)(mei)氣(qi)(qi)切斷設備，在操(cao)作(zuo)(zuo)過程中，煤(mei)(mei)氣(qi)(qi)外(wai)泄仍是 不An全因(yin)素(su)之一，容易產生中毒事故。

實用新型內容

本實用新型的技術任(ren)務是針對以上(shang)不(bu)足之處，提供電動推桿盲板(ban)閥，通(tong)過 自力切(qie)斷方式來解決上(shang)述(shu)缺(que)點。

本實用新型解決其技術(shu)問(wen)題所(suo)采用的(de)技術(shu)方案是電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)(gan)(gan)盲板(ban)閥，其機(ji) 構包括盲板(ban)閥和電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)(gan)(gan)，所(suo)述的(de)坐落在帶有支撐住的(de)機(ji)座上的(de)盲板(ban)閥是由通(tong) 過(guo)絲(si)桿(gan)(gan)(gan)(gan)(gan)付連接(jie)的(de)左(zuo)閥體(ti)(ti)(ti)和右閥體(ti)(ti)(ti)、設置(zhi)于左(zuo)右閥體(ti)(ti)(ti)之(zhi)間的(de)閥板(ban)組成(cheng)，閥板(ban)一邊(bian) 通(tong)過(guo)連桿(gan)(gan)(gan)(gan)(gan)連接(jie)，而另(ling)一端則通(tong)過(guo)轉(zhuan)桿(gan)(gan)(gan)(gan)(gan)鉸接(jie)在左(zuo)右閥體(ti)(ti)(ti)頂端的(de)一個絲(si)桿(gan)(gan)(gan)(gan)(gan)付上，盲 板(ban)閥左(zuo)方設置(zhi)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)(gan)(gan)，所(suo)述電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)(gan)(gan)分為啟閉電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)(gan)(gan)和翻板(ban)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)(gan)(gan)，這 兩個推(tui)桿(gan)(gan)(gan)(gan)(gan)均通(tong)過(guo)轉(zhuan)桿(gan)(gan)(gan)(gan)(gan)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)閥板(ban)動(dong)(dong)(dong)(dong)(dong)(dong)作。啟閉電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)(gan)(gan)通(tong)過(guo)絲(si)桿(gan)(gan)(gan)(gan)(gan)螺旋付驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)左(zuo)、右 閥體(ti)(ti)(ti)完(wan)(wan)成(cheng)松開、夾緊(jin)動(dong)(dong)(dong)(dong)(dong)(dong)作。翻板(ban)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)(gan)(gan)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)閥板(ban)完(wan)(wan)成(cheng)開閉動(dong)(dong)(dong)(dong)(dong)(dong)作。橡膠密封圈 鑲嵌在閥板(ban)上.密封性能好(hao)，更換(huan)方便。

所述(shu)的(de)電(dian)(dian)動(dong)(dong)推桿(gan)由電(dian)(dian)動(dong)(dong)機、減速齒輪(lun)、絲桿(gan)、銅(tong)螺母(mu)、導向(xiang)套(tao)、活(huo)塞(sai)桿(gan)、軸承座、彈簧、缸(gang)簡、缸(gang)筒座等部件所組(zu)成，電(dian)(dian)動(dong)(dong)機通過一級或二齒輪(lun)減速后，帶動(dong)(dong)轉(zhuan)桿(gan)沿(yan)絲桿(gan)付把電(dian)(dian)動(dong)(dong)機的(de)旋轉(zhuan)運(yun)(yun)動(dong)(dong)變為直線(xian)運(yun)(yun)動(dong)(dong)，利用(yong)電(dian)(dian)動(dong)(dong)機正(zheng)反轉(zhuan) 實現(xian)推桿(gan)往復(fu)動(dong)(dong)作(zuo)。

輸(shu)出推拉力(li)(li)相(xiang)等，通過(guo)各種(zhong)杠桿、搖桿、連(lian)桿等結構，可 完成(cheng)轉(zhuan)動(dong)或(huo)搖動(dong)等復雜(za)動(dong)作(zuo)，通過(guo)改變(bian)杠桿力(li)(li)臂長度，可以增(zeng)長行程。

過(guo)載自動(dong)保護功能電動(dong)推桿(gan)內(nei)設過(guo)載自動(dong)保護裝置(zhi)，當(dang)推桿(gan)行(xing)程(cheng)到Ji限(xian)位(wei)置(zhi)或負(fu)載 超過(guo)額定推力一(yi)定數值時(shi)，推桿(gan)將自動(dong)切斷電源，起到保護作用，使電動(dong)機及 其(qi)它(ta)構(gou)件(jian)不(bu)(bu)致損壞，但不(bu)(bu)得以此作為正常(chang)運行(xing)時(shi)限(xian)位(wei)開關使用。因此在本機上 另行(xing)配置(zhi)內(nei)行(xing)程(cheng)限(xian)位(wei)開關裝置(zhi)，以控制推桿(gan)正常(chang)起停。
