換向閥工作原理：

六通(tong)換向閥(fa)(fa)(fa)(fa)主(zhu)要由(you)閥(fa)(fa)(fa)(fa)體、密封(feng)組(zu)(zu)件(jian)(jian)、凸輪、閥(fa)(fa)(fa)(fa)桿、手(shou)(shou)柄和閥(fa)(fa)(fa)(fa)蓋(gai)(gai)等(deng)零部件(jian)(jian)組(zu)(zu)成閥(fa)(fa)(fa)(fa)門由(you)手(shou)(shou)柄驅動(dong)，通(tong)過手(shou)(shou)柄帶動(dong)閥(fa)(fa)(fa)(fa)桿與凸輪旋轉(zhuan)，凸輪具有定位驅動(dong)與鎖定密封(feng)組(zu)(zu)件(jian)(jian)的開啟與關閉(bi)功能。手(shou)(shou)柄逆時針旋轉(zhuan)，兩(liang)(liang)組(zu)(zu)密封(feng)組(zu)(zu)件(jian)(jian)分別(bie)在凸輪的作用(yong)下關閉(bi)下端(duan)的兩(liang)(liang)個(ge)通(tong)道(dao)(dao)(dao)，上(shang)端(duan)的兩(liang)(liang)個(ge)通(tong)道(dao)(dao)(dao)分別(bie)與管道(dao)(dao)(dao)裝(zhuang)置的進口(kou)相通(tong)。反之(zhi)，上(shang)端(duan)的兩(liang)(liang)個(ge)通(tong)道(dao)(dao)(dao)關閉(bi)，下端(duan)兩(liang)(liang)個(ge)通(tong)道(dao)(dao)(dao)與管道(dao)(dao)(dao)裝(zhuang)置的進口(kou)相通(tong)，實現(xian)了不(bu)停車換向。上(shang)閥(fa)(fa)(fa)(fa)蓋(gai)(gai) 2手(shou)(shou)柄 3閥(fa)(fa)(fa)(fa)桿 4凸輪 5密封(feng)組(zu)(zu)件(jian)(jian) 6閥(fa)(fa)(fa)(fa)蓋(gai)(gai) 7閥(fa)(fa)(fa)(fa)體 

（1）六(liu)通閥(fa)的閥(fa)體由(you)隔(ge)板分成(cheng)兩腔(qiang)(qiang)，每腔(qiang)(qiang)都(dou)有(you)3個通道(dao)，中間為(wei)進(jin)油口，兩端為(wei)出油口。閥(fa)體為(wei)碳(tan)鋼板焊結構，體積小(xiao)，質(zhi)量(liang)輕，結構緊(jin)湊，提高了(le)材料的利用率，縮短了(le)生產周期，降(jiang)低了(le)成(cheng)本。密(mi)封(feng)(feng)面堆焊不(bu)銹(xiu)(xiu)鋼，防銹(xiu)(xiu)耐腐(fu)蝕，密(mi)封(feng)(feng)面經過精加工后拋光研磨，表面粗糙度Ra≤0.8μm。

（2）六通(tong)閥(fa)有(you)兩組(zu)(zu)密(mi)(mi)封(feng)(feng)組(zu)(zu)件。每組(zu)(zu)密(mi)(mi)封(feng)(feng)組(zu)(zu)件由閥(fa)瓣(ban)(ban)、密(mi)(mi)封(feng)(feng)圈(quan)、調(diao)(diao)(diao)整(zheng)(zheng)塊(kuai)、調(diao)(diao)(diao)節螺釘(ding)(ding)、夾板(ban)和螺栓(shuan)組(zu)(zu)成。閥(fa)瓣(ban)(ban)為碳鋼(gang)板(ban)焊件，設有(you)加強(qiang)筋，即增加閥(fa)瓣(ban)(ban)強(qiang)度(du)又起導向作(zuo)用(yong)，保證每組(zu)(zu)閥(fa)瓣(ban)(ban)間的同(tong)軸度(du)。閥(fa)瓣(ban)(ban)上鑲(xiang)嵌聚氨脂橡(xiang)膠圈(quan)，該材料具有(you)耐(nai)油、耐(nai)磨損、性能(neng)(neng)穩定、密(mi)(mi)封(feng)(feng)良好和使用(yong)壽命長的特點。在(zai)凸(tu)輪的作(zuo)用(yong)下，密(mi)(mi)封(feng)(feng)圈(quan)的球(qiu)面(mian)與閥(fa)體密(mi)(mi)封(feng)(feng)面(mian)相接觸產生(sheng)擠(ji)壓彈性變形，達到(dao)密(mi)(mi)封(feng)(feng)效果(guo)。調(diao)(diao)(diao)整(zheng)(zheng)塊(kuai)和調(diao)(diao)(diao)節螺釘(ding)(ding)在(zai)兩組(zu)(zu)密(mi)(mi)封(feng)(feng)組(zu)(zu)件不能(neng)(neng)同(tong)步到(dao)位時可(ke)起調(diao)(diao)(diao)整(zheng)(zheng)作(zuo)用(yong)，確保各通(tong)道密(mi)(mi)封(feng)(feng)性能(neng)(neng)同(tong)步到(dao)位1夾板(ban) 2螺栓(shuan) 3調(diao)(diao)(diao)整(zheng)(zheng)塊(kuai) 4閥(fa)瓣(ban)(ban) 5密(mi)(mi)封(feng)(feng)圈(quan) 6調(diao)(diao)(diao)整(zheng)(zheng)螺釘(ding)(ding)

（3）閥(fa)桿與閥(fa)體(ti)隔板和上閥(fa)蓋(gai)間的軸向密封采用O形圈。

電(dian)(dian)(dian)磁(ci)(ci)(ci)閥是由電(dian)(dian)(dian)磁(ci)(ci)(ci)線(xian)圈(quan)和磁(ci)(ci)(ci)芯(xin)組(zu)成，是包含一(yi)個(ge)或(huo)幾個(ge)孔的(de)閥體(ti)(ti)。當線(xian)圈(quan)通電(dian)(dian)(dian)或(huo)斷電(dian)(dian)(dian)時，磁(ci)(ci)(ci)芯(xin)的(de)運轉將導致流體(ti)(ti)通過閥體(ti)(ti)或(huo)被切斷，以(yi)達到(dao)改變(bian)流體(ti)(ti)方向的(de)目的(de)。電(dian)(dian)(dian)磁(ci)(ci)(ci)閥的(de)電(dian)(dian)(dian)磁(ci)(ci)(ci)部件由固定鐵芯(xin)、動鐵芯(xin)、線(xian)圈(quan)等部件組(zu)成；閥體(ti)(ti)部分由滑閥芯(xin)、滑閥套、彈簧底座等組(zu)成。電(dian)(dian)(dian)磁(ci)(ci)(ci)線(xian)圈(quan)被直接安裝(zhuang)在(zai)閥體(ti)(ti)上，閥體(ti)(ti)被封(feng)閉在(zai)密封(feng)管中，構成一(yi)個(ge)簡潔、緊湊(cou)的(de)組(zu)合。
