手動電動插板閥原理和技術參數

根據除塵器的在功能的不同，插板閥可分(fen)為(wei)手(shou)動型(xing)插(cha)板(ban)閥(fa)、氣(qi)動插(cha)板(ban)閥(fa)和電(dian)動插(cha)板(ban)閥(fa)。手(shou)動插(cha)板(ban)閥(fa)根據其操作(zuo)結構形式(shi)可分(fen)為(wei)螺桿型(xing)和手(shou)柄型(xing)兩種，一(yi)般(ban)與旋轉閥(fa)配套使用，僅作(zuo)為(wei)旋轉閥(fa)檢修時的灰(hui)斗(dou)切斷作(zuo)用，如除塵(chen)器灰(hui)斗(dou)的卸灰(hui)等;氣(qi)動型(xing)插(cha)板(ban)閥(fa)用于粉塵(chen)自動排(pai)出(chu)控制(zhi)，在電(dian)爐除塵(chen)系統(tong)中可用于沉(chen)(chen)降室(shi)(shi)(shi)或燃燒室(shi)(shi)(shi)灰(hui)斗(dou)的排(pai)灰(hui);電(dian)動型(xing)插(cha)板(ban)閥(fa)，用于粉塵(chen)和漿液等的自動排(pai)出(chu)控制(zhi)，在電(dian)爐除塵(chen)系統(tong)中可用于沉(chen)(chen)降室(shi)(shi)(shi)或燃燒室(shi)(shi)(shi)灰(hui)斗(dou)的排(pai)灰(hui)。

　　插(cha)板(ban)(ban)(ban)閥(fa)(fa)的(de)(de)功(gong)能簡(jian)單(dan)但又不(bu)可或缺。插(cha)板(ban)(ban)(ban)閥(fa)(fa)只是(shi)單(dan)純(chun)的(de)(de)開關(guan)功(gong)能，并不(bu)能進行定(ding)量供給，只是(shi)提供開關(guan)供其(qi)(qi)它閥(fa)(fa)門和(he)設備短暫維護和(he)更換(huan)時截(jie)斷物(wu)料(liao)流。插(cha)板(ban)(ban)(ban)閥(fa)(fa)的(de)(de)使(shi)用(yong)(yong)雖然(ran)簡(jian)單(dan)但是(shi)它是(shi)的(de)(de)截(jie)門，構(gou)造(zao)簡(jian)單(dan)而(er)故障率低，易于拆卸和(he)保養，可自(zi)己更換(huan)其(qi)(qi)中的(de)(de)配件而(er)不(bu)影響其(qi)(qi)使(shi)用(yong)(yong)，受(shou)負壓使(shi)用(yong)(yong)的(de)(de)影響，插(cha)板(ban)(ban)(ban)閥(fa)(fa)的(de)(de)使(shi)用(yong)(yong)大多與(yu)葉輪(lun)給料(liao)機相互配合(he)使(shi)用(yong)(yong)。插(cha)板(ban)(ban)(ban)閥(fa)(fa)普通型用(yong)(yong)于常溫時候使(shi)用(yong)(yong)，對(dui)高溫物(wu)料(liao)和(he)有(you)腐(fu)蝕性的(de)(de)物(wu)料(liao)可根據使(shi)用(yong)(yong)情況來定(ding)制(zhi)，但插(cha)板(ban)(ban)(ban)閥(fa)(fa)不(bu)應用(yong)(yong)于高密封性閥(fa)(fa)門處(chu)和(he)氣體截(jie)斷的(de)(de)閥(fa)(fa)門用(yong)(yong)，這(zhe)會使(shi)插(cha)板(ban)(ban)(ban)閥(fa)(fa)起不(bu)到應有(you)的(de)(de)作用(yong)(yong)，也是(shi)我們產(chan)品設計之初(chu)沒(mei)有(you)的(de)(de)功(gong)能。

　　插(cha)板(ban)(ban)閥(fa)(fa)一(yi)般可分為電動(dong)(dong)(dong)(dong)插(cha)板(ban)(ban)閥(fa)(fa)、電液動(dong)(dong)(dong)(dong)、氣動(dong)(dong)(dong)(dong)插(cha)板(ban)(ban)閥(fa)(fa),手動(dong)(dong)(dong)(dong)插(cha)板(ban)(ban)閥(fa)(fa)四(si)種。插(cha)板(ban)(ban)閥(fa)(fa)通(tong)常(chang)由(you)閥(fa)(fa)體、閥(fa)(fa)板(ban)(ban)、閥(fa)(fa)板(ban)(ban)框(kuang)架、絲杠(gang)夾緊(jin)驅(qu)動(dong)(dong)(dong)(dong)裝置(zhi)(zhi)、膨(peng)脹(zhang)節(jie)和(he)(he)閥(fa)(fa)板(ban)(ban)行(xing)走驅(qu)動(dong)(dong)(dong)(dong)裝置(zhi)(zhi)等部(bu)件(jian)組成(cheng)。閥(fa)(fa)板(ban)(ban)是由(you)通(tong)板(ban)(ban)和(he)(he)盲板(ban)(ban)組成(cheng)的，控制介質(zhi)的流(liu)通(tong)和(he)(he)截斷；浮(fu)動(dong)(dong)(dong)(dong)座(zuo)與波(bo)紋膨(peng)脹(zhang)節(jie)焊接在一(yi)起(qi)，行(xing)走驅(qu)動(dong)(dong)(dong)(dong)裝置(zhi)(zhi)帶(dai)動(dong)(dong)(dong)(dong)閥(fa)(fa)板(ban)(ban)框(kuang)架移(yi)動(dong)(dong)(dong)(dong)，以實(shi)現(xian)(xian)通(tong)孔閥(fa)(fa)板(ban)(ban)和(he)(he)不通(tong)孔閥(fa)(fa)板(ban)(ban)的轉(zhuan)換；夾緊(jin)驅(qu)動(dong)(dong)(dong)(dong)裝置(zhi)(zhi)通(tong)過(guo)鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)帶(dai)動(dong)(dong)(dong)(dong)絲杠(gang)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)(zhi)同時旋(xuan)轉(zhuan)，實(shi)現(xian)(xian)絲杠(gang)螺母帶(dai)動(dong)(dong)(dong)(dong)浮(fu)動(dong)(dong)(dong)(dong)座(zuo)水平(ping)移(yi)動(dong)(dong)(dong)(dong)，使浮(fu)動(dong)(dong)(dong)(dong)座(zuo)密封面壓緊(jin)閥(fa)(fa)板(ban)(ban)上的O形圈，閥(fa)(fa)門(men)實(shi)現(xian)(xian)密封。

　　電動插板閥是一種(zhong)閘(zha)板與(yu)閥座(zuo)始終緊密(mi)接觸密(mi)封的(de)(de)閥門。電動插板閥啟閉(bi)件是閘(zha)板，閘(zha)板的(de)(de)運動方(fang)向(xiang)與(yu)流體方(fang)向(xiang)相垂直，電動插板閥只能作(zuo)全開(kai)和(he)(he)全關，不能作(zuo)調節和(he)(he)節流。閘(zha)板有兩(liang)(liang)個密(mi)封面，模(mo)式閘(zha)板閥的(de)(de)兩(liang)(liang)個密(mi)封面形(xing)成楔(xie)形(xing)、楔(xie)形(xing)角隨閥門參(can)數而異。
