style="text-indent:25px">風(fēng)量調(diào)節(jié)閥又叫調(diào)風(fēng)門，是工業(yè)廠房民用建筑的通風(fēng)、空氣調(diào)節(jié)及空氣凈化工程中不可缺少的中央空調(diào)末端配件，一般用在空調(diào)，通風(fēng)系統(tǒng)管道中，用來調(diào)節(jié)支管的風(fēng)量，也可用于新風(fēng)與回風(fēng)的混合調(diào)節(jié)。特點：（1）對開多葉風(fēng)量調(diào)節(jié)閥接管尺寸與全國通風(fēng)管道標(biāo)準(zhǔn)化規(guī)定的矩形風(fēng)管尺寸相同。（2）風(fēng)量調(diào)節(jié)閥葉片為對開式和順開式，在通風(fēng)、空氣調(diào)節(jié)、空氣凈化系統(tǒng)中作為調(diào)節(jié)閥。（3）通過試驗測定，風(fēng)量調(diào)節(jié)閥的氣密性好，其相對漏風(fēng)量在5%左右，調(diào)節(jié)性能好。結(jié)構(gòu)特征：（1）該風(fēng)量調(diào)節(jié)閥在葉片寬度全統(tǒng)一為四種規(guī)格，葉片狀為菱形雙葉片，葉片間采用軟搭接，因此密閉性能良好。（2）風(fēng)量調(diào)節(jié)閥閥體構(gòu)架用2毫米鍍鋅板冷軋成型后,以二氧化碳?xì)怏w保護(hù)焊接或由普通Q235板加工焊接而成；葉片用1毫米鍍鋅板冷軋為瓦楞形，兩片合成點焊插方軸，或2毫米G235鋼板冷壓成形，單片沖孔插方軸或焊圓軸。（3）該調(diào)節(jié)閥分手動、電動，按所用材料分：鐵板、鍍鋅板、鋁合金板、不銹鋼板四種，閥體結(jié)構(gòu)及規(guī)格尺寸相同。</p><p style="text-indent:25px">定風(fēng)量調(diào)節(jié)閥其實就是一種機械式自力裝置，比較適合于通風(fēng)空調(diào)系統(tǒng)中。定風(fēng)量調(diào)節(jié)閥能夠依靠風(fēng)管內(nèi)氣流力來定位控制閥門的位置，從而在整個壓力差范圍內(nèi)將氣流保持在預(yù)先設(shè)定的流量上?，F(xiàn)在定風(fēng)量調(diào)節(jié)閥在新風(fēng)系統(tǒng)的應(yīng)先用還是非常普遍的，特別是賓館客房部分，還有寫字樓、辦公樓這樣的地方。每層做法是每層設(shè)新風(fēng)機組，走道敷設(shè)新風(fēng)干管，幾十根支管分別從總管上接入各房間。以賓館客房為例，每間客房新風(fēng)量一般為100m3/h。通常來講，設(shè)計師往往會在新風(fēng)支管上加設(shè)一只定風(fēng)量調(diào)節(jié)閥，期望通過后期調(diào)試手段來完成風(fēng)量分配。風(fēng)量調(diào)節(jié)閥在葉片寬度全統(tǒng)一為四種規(guī)格，葉片狀為菱形雙葉片，葉片間采用軟搭接，因此密閉性能良好。</p><div

12220的規(guī)定。電動通風(fēng)蝶閥主要產(chǎn)品：大型通風(fēng)蝶閥，電動通風(fēng)蝶閥，泄露率為0，防爆通風(fēng)蝶閥。該閥驅(qū)動力矩小，啟閉靈活，操作控制方便。閥體上設(shè)置油密封擋圈，密封副之間無可見間隙，泄漏率小。蝶板與閥體間的膨脹間隙大，能有效防止因熱漲冷縮造成的卡死現(xiàn)象。本閥可配備多種驅(qū)動裝置，如手動裝置、蝸輪傳動裝置、氣動裝置、電動裝置。變風(fēng)量閥對于工作壓力大于1.0 MPa 及在主干管上起到切斷作用的閥門，安裝前應(yīng)進(jìn)行強度和嚴(yán)密性能試驗，合格后方準(zhǔn)使用。內(nèi)無連桿、螺栓(組成:頭部和螺桿組成)等、工作可靠、使用壽命長?？梢远喙の话惭b，不受介質(zhì)流向影響。風(fēng)量調(diào)節(jié)閥的恒流量功能是通過位于平衡器中間的硅膠囊的收縮和膨脹/收縮來實現(xiàn)的。韶關(guān)風(fēng)量調(diào)節(jié)閥哪家強</p><p
