手動防塵(chen)式插(cha)板門:
手(shou)動(dong)(dong)(dong)插(cha)板(ban)門也叫手(shou)動(dong)(dong)(dong)螺旋閘閥，大(da)多用(yong)于卸(xie)料器(qi)配套(tao)使用(yong)分為方口(kou)和(he)(he)圓(yuan)口(kou)兩種(zhong)。電動(dong)(dong)(dong)插(cha)板(ban)閥口(kou)型要根據卸(xie)料器(qi)形狀做出選擇。手(shou)動(dong)(dong)(dong)插(cha)板(ban)閥經(jing)久耐用(yong)，流動(dong)(dong)(dong)阻力(li)小，體積小，重量輕，維修方便，使用(yong)廣(guang)泛。電動(dong)(dong)(dong)插(cha)板(ban)閥密(mi)封結(jie)(jie)構(gou)可以分軟密(mi)封、硬密(mi)封結(jie)(jie)構(gou)。工藝性(xing)好，結(jie)(jie)構(gou)緊湊(cou)等特點，密(mi)封閥座(zuo)為活動(dong)(dong)(dong)結(jie)(jie)構(gou)設計，有防磨損和(he)(he)自動(dong)(dong)(dong)補(bu)償(chang)功(gong)能，因(yin)而(er)壽命更長。
用途
手(shou)動(dong)(dong)插(cha)板(ban)(ban)閥是(shi)粉料(liao)、晶粒料(liao)、小顆(ke)粒料(liao)的流量輸送控(kong)制(zhi)的主要設(she)(she)備。電(dian)動(dong)(dong)插(cha)板(ban)(ban)閥廣泛適用(yong)于冶金(jin)、礦(kuang)山、建材(cai)、糧(liang)食、化工等(deng)行業。插(cha)板(ban)(ban)閥配備電(dian)動(dong)(dong)、氣動(dong)(dong)、電(dian)液動(dong)(dong)推(tui)桿(gan)作為驅(qu)動(dong)(dong)裝置，是(shi)控(kong)制(zhi)流量大小，切斷迅(xun)速的理想設(she)(she)備。
手動插板(ban)閥(fa)采用(yong)優質(zhi)碳素鋼焊接(jie)而成，廣泛應用(yong)于冶金、食品、化工(gong)、建材等行業(ye)。多用(yong)于煙氣(qi)凈化系統的煙氣(qi)管路系統中(zhong)煙氣(qi)調節(jie)、切換作(zuo)用(yong)。
