VICKERS電磁閥工作原理; VICKERS電磁閥是(shi)用(yong)來控(kong)(kong)制(zhi)(zhi)流(liu)體(ti)方向的(de)(de)(de)自動 化基礎(chu)元件，屬于執行器(qi)；通(tong)常(chang)用(yong)于機械控(kong)(kong)制(zhi)(zhi)和工(gong)業(ye)閥(fa)門(men)上面(mian)，對介質方向進(jin)行控(kong)(kong)制(zhi)(zhi)，從而達到對閥(fa)門(men)開關的(de)(de)(de)控(kong)(kong)制(zhi)(zhi)。工(gong)作原理電磁閥(fa)里有(you)密閉的(de)(de)(de)腔(qiang)，在不(bu)同(tong)位置開有(you)通(tong)孔(kong)(kong)，每個孔(kong)(kong) 都(dou)通(tong)向不(bu)同(tong)的(de)(de)(de)油管(guan)，腔(qiang)中間(jian)是(shi)閥(fa)，兩(liang)面(mian)是(shi)兩(liang)塊電磁鐵(tie)，哪(na)面(mian)的(de)(de)(de)磁鐵(tie)線圈通(tong)電閥(fa)體(ti)就會(hui)(hui)被吸引到哪(na)邊，通(tong)過(guo)控(kong)(kong)制(zhi)(zhi)閥(fa)體(ti)的(de)(de)(de)移動來擋住或漏出不(bu)同(tong)的(de)(de)(de)排油的(de)(de)(de)孔(kong)(kong)，而進(jin)油孔(kong)(kong)是(shi)常(chang)開的(de)(de)(de)，液壓 油就會(hui)(hui)進(jin)入不(bu)同(tong)的(de)(de)(de)排油管(guan)，然后通(tong)過(guo)油的(de)(de)(de)壓力來推動油缸的(de)(de)(de)活(huo)塞(sai)，活(huo)塞(sai)又帶(dai)動活(huo)塞(sai)桿(gan)，活(huo)塞(sai)桿(gan)帶(dai)動機械裝(zhuang)置動。這樣通(tong)過(guo)控(kong)(kong)制(zhi)(zhi)電磁鐵(tie)的(de)(de)(de)電流(liu)通(tong)斷就控(kong)(kong)制(zhi)(zhi)了機械運動。 美國VICKERS電磁閥隔磁(ci)(ci)套管內的鐵芯(xin)完(wan)成(cheng)，不存在(zai)動密封，所以外漏(lou)易堵絕。電動閥(fa)力矩控(kong)制不易，容易產生內漏(lou)，甚至(zhi)拉斷(duan)閥(fa)桿(gan)頭部；電磁(ci)(ci)閥(fa)的結構(gou)型式容易控(kong)制內泄漏(lou) ，直至(zhi)降為零。 VICKERS電(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)(fa)的(de)(de)用途(tu)電(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)(fa)用于(yu)(yu)(yu)液體和氣(qi)體管(guan)(guan)(guan)路(lu)的(de)(de)開(kai)關(guan)控(kong)(kong)制(zhi)(zhi)(zhi)，是(shi)(shi)兩(liang)位DO控(kong)(kong)制(zhi)(zhi)(zhi)。一(yi)(yi)般用于(yu)(yu)(yu)小 型管(guan)(guan)(guan)道(dao)(dao)的(de)(de)控(kong)(kong)制(zhi)(zhi)(zhi)。電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)閥(fa)(fa)(fa)(fa)(fa)用于(yu)(yu)(yu)液體、氣(qi)體和風系統管(guan)(guan)(guan)道(dao)(dao)介質流(liu)量的(de)(de)模擬量調(diao)節，是(shi)(shi)AI控(kong)(kong)制(zhi)(zhi)(zhi)。在大(da)型閥(fa)(fa)(fa)(fa)(fa)門和風系統的(de)(de)控(kong)(kong)制(zhi)(zhi)(zhi)中也可以用電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)閥(fa)(fa)(fa)(fa)(fa)做兩(liang)位開(kai)關(guan)控(kong)(kong)制(zhi)(zhi)(zhi)。電(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)(fa)只能用作(zuo)開(kai)關(guan)量，是(shi)(shi)DO控(kong)(kong)制(zhi)(zhi)(zhi)，只能用于(yu)(yu)(yu)小管(guan)(guan)(guan)道(dao)(dao)控(kong)(kong)制(zhi)(zhi)(zhi)，常見于(yu)(yu)(yu)DN50及(ji)以下管(guan)(guan)(guan)道(dao)(dao)，往上就很少了。電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)閥(fa)(fa)(fa)(fa)(fa)可以有AI反饋(kui)信號，可以由DO或(huo)AO控(kong)(kong)制(zhi)(zhi)(zhi)，比(bi)較見于(yu)(yu)(yu)大(da)管(guan)(guan)(guan)道(dao)(dao)和風閥(fa)(fa)(fa)(fa)(fa)等。1.開(kai)關(guan)形式電(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)(fa)通(tong)(tong)過線圈驅動(dong)(dong)(dong)(dong)(dong)，只能開(kai)或(huo)關(guan)，開(kai)關(guan)時動(dong)(dong)(dong)(dong)(dong)作(zuo)時間短。電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)閥(fa)(fa)(fa)(fa)(fa)的(de)(de)驅動(dong)(dong)(dong)(dong)(dong)一(yi)(yi)般是(shi)(shi)用電(dian)(dian)(dian)(dian)機，開(kai)或(huo)關(guan)動(dong)(dong)(dong)(dong)(dong)作(zuo)完(wan)成需要一(yi)(yi)定的(de)(de)時間模擬量的(de)(de)，可以做調(diao)節。2.工(gong)作(zuo)性質電(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)(fa)一(yi)(yi)般流(liu)通(tong)(tong)系數很小，而且工(gong)作(zuo)壓 力差很小。比(bi)如(ru)一(yi)(yi)般25口徑(jing)的(de)(de)電(dian)(dian)(dian)(dian)磁閥(fa)(fa)(fa)(fa)(fa)流(liu)通(tong)(tong)系數比(bi)15口徑(jing)的(de)(de)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)球閥(fa)(fa)(fa)(fa)(fa)小很多。 VICKERS電磁閥的主要特點 (1)外(wai)漏(lou)(lou)(lou)堵絕，內(nei)漏(lou)(lou)(lou)易(yi)(yi)控(kong)(kong)，使用(yong)(yong)安(an)(an)全(quan)(quan)。內(nei)外(wai)泄漏(lou)(lou)(lou)是危及安(an)(an)全(quan)(quan)的要素。其它自控(kong)(kong)閥(fa)(fa)通常將(jiang)閥(fa)(fa)桿伸出(chu)，由電動(dong)(dong)、氣動(dong)(dong)、液動(dong)(dong)執行機(ji)構(gou)控(kong)(kong)制閥(fa)(fa)芯的轉動(dong)(dong)或移動(dong)(dong) 。這都要解決長(chang)期(qi)動(dong)(dong)作閥(fa)(fa)桿動(dong)(dong)密封的外(wai)泄漏(lou)(lou)(lou)難題；唯有(you)電磁(ci)閥(fa)(fa)是用(yong)(yong)電磁(ci)力作用(yong)(yong)于密封在電動(dong)(dong)調節閥(fa)(fa)隔磁(ci)套管內(nei)的鐵芯完成，不存在動(dong)(dong)密封，所以(yi)外(wai)漏(lou)(lou)(lou)易(yi)(yi)堵絕。電動(dong)(dong)閥(fa)(fa)力矩(ju)控(kong)(kong)制不易(yi)(yi) ，容(rong)易(yi)(yi)產(chan)生內(nei)漏(lou)(lou)(lou)，甚至(zhi)拉斷閥(fa)(fa)桿頭部；電磁(ci)閥(fa)(fa)的結(jie)構(gou)型式(shi)容(rong)易(yi)(yi)控(kong)(kong)制內(nei)泄漏(lou)(lou)(lou)，直至(zhi)降(jiang)為零(ling)。所以(yi)，電磁(ci)閥(fa)(fa)使用(yong)(yong)特(te)別安(an)(an)全(quan)(quan)，尤其適(shi)用(yong)(yong)于腐蝕性、有(you)毒(du)或高低溫(wen)的介(jie)質。 (2)系(xi)統簡(jian)單， 便接電(dian)腦，價(jia)格(ge)低(di)謙。電(dian)磁(ci)閥(fa)(fa)本身(shen)結構簡(jian)單，價(jia)格(ge)也低(di)，比起調節閥(fa)(fa)等(deng)其它種(zhong)類(lei)執(zhi)行器易于安裝維(wei)護。更顯(xian)著的(de)是所組(zu)成的(de)自控(kong)(kong)(kong)系(xi)統簡(jian)單得多(duo)，價(jia)格(ge)要低(di)得多(duo)。由于電(dian)磁(ci)閥(fa)(fa)是開(kai)關 信號(hao)控(kong)(kong)(kong)制，與工(gong)控(kong)(kong)(kong)計算機連接十分方(fang)便。在當(dang)今電(dian)腦普及，價(jia)格(ge)大幅下(xia)降的(de)時(shi)代，電(dian)磁(ci)閥(fa)(fa)的(de)優勢(shi)就(jiu)更加(jia)明(ming)顯(xian)。 (3)動(dong)作快遞，功(gong)率微小，外形輕(qing)巧(qiao)。電磁(ci)(ci)閥響應時間可(ke)(ke)以(yi)短(duan)至幾個 毫(hao)秒(miao)(miao)，即使是先導式(shi)電磁(ci)(ci)閥也可(ke)(ke)以(yi)控制(zhi)在幾十毫(hao)秒(miao)(miao)內。由于自成回路，比之(zhi)其它自控閥反應更靈敏。設(she)計得當的電磁(ci)(ci)閥線圈功(gong)率消耗很低，屬節能產品(pin)；還可(ke)(ke)做到只需觸(chu)發動(dong)作， 自動(dong)保持(chi)閥位，平時一點也不耗電。電磁(ci)(ci)閥外形尺寸小，既節省空間，又(you)輕(qing)巧(qiao)美觀。 (4)調節精度受限，適用介(jie)(jie)(jie)質(zhi)受限。電磁閥(fa)通常只有開關兩種狀態，閥(fa)芯只能(neng)(neng)處于兩個極限位置，不(bu)能(neng)(neng)連續(xu)調節，(力圖(tu)突破的新(xin)構思不(bu)少，但還(huan)都處于試(shi)驗試(shi)用階段)所以調節精度還(huan)受到一(yi)定(ding)限制。電磁閥(fa)對(dui)介(jie)(jie)(jie)質(zhi)潔凈(jing)度有較(jiao)高要求，含(han)顆粒(li)狀的介(jie)(jie)(jie)質(zhi)不(bu)能(neng)(neng)適用，如屬雜(za)質(zhi) 須(xu)先濾去。另(ling)外，粘稠狀介(jie)(jie)(jie)質(zhi)不(bu)能(neng)(neng)適用，而且，特定(ding)的產品適用的介(jie)(jie)(jie)質(zhi)粘度范圍相對(dui)較(jiao)窄。 (5)型號多樣，用(yong)途廣(guang)泛。電(dian)磁(ci)(ci)閥雖有先天不足，優點仍(reng)十分突出，所以(yi)就設計(ji)成多種(zhong) 多樣的(de)(de)產品，滿足各種(zhong)不同的(de)(de)需求，用(yong)途極(ji)為廣(guang)泛。電(dian)磁(ci)(ci)閥技術(shu)的(de)(de)進步也都是圍繞(rao)著如(ru)何(he)克服先天不足，如(ru)何(he)更(geng)好地發揮固有優勢而展開。 VICKERS電磁閥的用途： 電磁閥用于液體和氣體管路的開關控制，是兩位DO控制。一般用于小 型管道的控制。電動閥用于液體、氣體和風系統管道介質流量的模擬量調節，是AI控制。在大型閥門和風系統的控制中也可以用電動閥做兩位開關控制。電磁閥只能用作開關量，是DO控制，只能用于小管道控制，常見于DN50及以下管道，往上就很少了。電動閥可以有AI反饋信號，可以由DO或AO控制，比較見于大管道和風閥等。
1.開關形式電磁閥通過線圈驅動，只能開或關，開關時動作時間短。電動閥的驅動一般是用電機，開或關動作完成需要一定的時間模擬量的，可以做調節。
2.工(gong)作性質電磁(ci)(ci)閥(fa)一(yi)般流通系數很小，而且工(gong)作壓 力差很小。比(bi)如一(yi)般25口徑的電磁(ci)(ci)閥(fa)流通系數比(bi)15口徑的電動球閥(fa)小很多。 美國進口威格士電磁閥系列型號： DG4V-3-0A-M-U-H7-60 DG4V-3-0AL-M-U-H7-60 DG4V-3-2A-M-U-H7-60 DG4V-3-22A-M-U-H7-60 DG4V-3-22AL-M-U-H7-60 DG4V-3-0B-M-U-H7-60 DG4V-3-2BL-M-U-H7-60 DG4V-3-2B-M-U-H7-60 DG4V-3-6B-M-U-H7-60 DG4V-3-2N-M-U-H7-60 DG4V-3-OC-M-U-H7-60 DG4V-3-2C-M-U-H7-60 DG4V-3-2C-M-U-H5-60-EN124 DG4V-3-3C-M-U-H7-60 DG4V-3-6C-M-U-H7-60 DG4V-3-6C-M-U-H7-60-EN124 DG4V-3-7C-M-U-H7-60 DG4V-3-8C-VM-U-H7-60 DG4V-3-31C-M-U-H7-60 DG4V-5-0A-M-U-H6-20 DG4V-5-0A-M-U-H6-20-EN124 DG4V-5-2AJ-M-U-H6-20 DG4V-5-22AJ-M-U-H6-20 DG4V-5-0CJ-M-U-H6-20 DG4V-5-2CJ-M-U-H6-20 DG4V-5-2NJ-M-U-H6-20 DG4V-5-3CJ-M-U-H6-20-EN124 DG4V-3-2A-M-FW-B6-60 DG4V-3-0A-M-U-B6-60 DG4V-3-0B-M-U-C6-60 DG4V-3-0B-M-U-H7-60 DG4V-3-22A-MU-D6-60 DG4V-3-22A-M-U-D6-60 DG4V-3-22A-M-U-H7-60-EN2-1 DG4V-3-2A-M-U1-H7-60 DG4V-3-2A-M-U-C6-60 DG4V-3-2A-VM-U-C6-60 DG4V-3-2A-VM-U-H7-60 DG4V-3-2A-Z-M-U-A6-60 DG4V-3-2A-Z-M-U-C6-60 DG4V-3-2C-M-FW-B6-60 DG4V-3-2N-M-U-A6-60 DG4V-3-2N-M-U-C6-60 DG4V-3-2A-M-U-C-60 DG4V-3-2C-H-U-L-CDL-60 DG4V-3S-6C-M-FW-B5-60 DG4V-3-2A-M-U-H7-60 DG4V-3-2N-M-U-H7-60 DG4V-5-6C-M-U-H6-20 DG4V-3-2N-M-U-D6-60 DG4V-3-33C208-MUHH760 DG4V-3-33C-M-U-H7-60 DG4V-3-52BL-M-U-H7-60 DG4V-3-6C-M-P2-T7-52 DG4V-3-2A-A-D24-6Y DG4M4-34C-20-JA DG4V-3-2AL-MU-H7-60 DG4V-3-2C-M-U-D6-60 DG4V-3-2C-M-U-H7-60 DG4V-5-0A-A-D-24-6Y DG4V-3-6C-M-U-H7-60 DG4V-3-6C-VM-U-H7-60 DG4V-3-6N-M-FTWL-B6-60 DG4V-3-7C-M-U-D6-60 DG4V-3-8C-M-P7-H-7-50 DG4V-3-8C-VM-U-C6-61 DG4V-3-8C-VM-U-C6-61 DG4V-3S-0B206-M-U-H5-60-EN493 DG4V-3S-0C-M-U-H5-60 DG4V-3S-2A-M-FTWL-B5-60 DG4V-3S-2A-M-FTWL-H5-60 DG4V-3S-2A-MUC560 DG4V-3S-2A-M-U-G5-60 DG4V-3S-2B200-M-U-SH5-60 DG4V-3-2A-A-D24-6Y DG4V-5-0A-A-D-24-6Y DG4V-3S-2N-M-U-B5-60 DG4V-3S-2N-VM-U-H5-60 ; DG4V-3S-6C-M-U-B5-60 DG4V-3S-6C-M-U-H5-60 DG4V-3S-OBL-M-FPA5WL-D5-60 DG4V4-012C-M-U-H-5-10 DG4V4-012N-M-PBWL-B-5-10 DG4V-5-0A-M-U-H6-20 此版權信(xin)息屬于上海(hai)維特銳，欲了解(jie)更多相關產品，請(qing)點擊(ji)：VICKERS電磁閥(fa) |
