建筑給排水知識：日本SMC電磁閥性能特點概述

    SMC電(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)主要特(te)點電(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)外漏(lou)(lou)堵(du)絕，內(nei)漏(lou)(lou)易控，使用(yong)安全(quan)(quan)。內(nei)外泄(xie)漏(lou)(lou)是危及安全(quan)(quan)的(de)要素(su)。其它自控閥(fa)(fa)(fa)(fa)通(tong)常將閥(fa)(fa)(fa)(fa)桿(gan)伸出，由電(dian)動(dong)(dong)、氣動(dong)(dong)、液動(dong)(dong)執行機(ji)構(gou)控制閥(fa)(fa)(fa)(fa)芯(xin)的(de)轉動(dong)(dong)或移動(dong)(dong)。這都(dou)要解決長期動(dong)(dong)作閥(fa)(fa)(fa)(fa)桿(gan)動(dong)(dong)密封的(de)外泄(xie)漏(lou)(lou)難題(ti);唯(wei)有電(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)是用(yong)電(dian)磁(ci)(ci)力(li)(li)作用(yong)于密封在電(dian)動(dong)(dong)調節(jie)閥(fa)(fa)(fa)(fa)隔磁(ci)(ci)套管內(nei)的(de)鐵芯(xin)完成，不存在動(dong)(dong)密封，所以(yi)外漏(lou)(lou)易堵(du)絕。電(dian)動(dong)(dong)閥(fa)(fa)(fa)(fa)力(li)(li)矩控制不易，容易產生內(nei)漏(lou)(lou)，甚至拉斷(duan)閥(fa)(fa)(fa)(fa)桿(gan)頭部;電(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)結(jie)構(gou)型(xing)式容易控制內(nei)泄(xie)漏(lou)(lou)，直至降為(wei)零。所以(yi)，電(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)使用(yong)特(te)別安全(quan)(quan)，尤其適(shi)用(yong)于腐蝕(shi)性、有毒或高低溫的(de)介質。

    SMC電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)系統(tong)簡(jian)(jian)單，便接(jie)電(dian)(dian)(dian)(dian)腦，價格(ge)低謙。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)本(ben)身結構簡(jian)(jian)單，價格(ge)也(ye)低，比(bi)起調(diao)節(jie)閥(fa)(fa)等(deng)其(qi)它種(zhong)類執行器(qi)易于(yu)(yu)安(an)裝維護(hu)。更(geng)(geng)顯著(zhu)的(de)是所(suo)組成(cheng)的(de)自控(kong)系統(tong)簡(jian)(jian)單得多(duo)，價格(ge)要(yao)低得多(duo)。由于(yu)(yu)電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)是開(kai)關(guan)(guan)信號(hao)控(kong)制(zhi)，與工(gong)控(kong)計算機連(lian)接(jie)十分方便。在(zai)當今電(dian)(dian)(dian)(dian)腦普及，價格(ge)大幅下降的(de)時代，電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)的(de)優(you)(you)勢(shi)就(jiu)更(geng)(geng)加(jia)明(ming)顯。SMC電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)動(dong)(dong)作快遞，功(gong)率微小，外形(xing)輕(qing)巧。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)響應時間可以(yi)短至(zhi)幾個(ge)毫秒，即使是先導式電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)也(ye)可以(yi)控(kong)制(zhi)在(zai)幾十毫秒內。由于(yu)(yu)自成(cheng)回(hui)路，比(bi)之其(qi)它自控(kong)閥(fa)(fa)反應更(geng)(geng)靈敏。設計得當的(de)電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)線圈功(gong)率消耗很低，屬(shu)節(jie)能產品;還(huan)可做到只需(xu)觸發動(dong)(dong)作，自動(dong)(dong)保持(chi)閥(fa)(fa)位，平(ping)時一(yi)點也(ye)不(bu)(bu)耗電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)外形(xing)尺寸小，既節(jie)省(sheng)空間，又輕(qing)巧美(mei)觀(guan)。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)調(diao)節(jie)精(jing)度(du)受限，適用(yong)介質(zhi)受限。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)通常只有(you)開(kai)關(guan)(guan)兩種(zhong)狀態(tai)，閥(fa)(fa)芯(xin)只能處于(yu)(yu)兩個(ge)極限位置，不(bu)(bu)能連(lian)續(xu)調(diao)節(jie)，（力圖突破的(de)新構思不(bu)(bu)少，但還(huan)都處于(yu)(yu)試驗(yan)試用(yong)階段(duan)）所(suo)以(yi)調(diao)節(jie)精(jing)度(du)還(huan)受到一(yi)定限制(zhi)。SMC電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)對介質(zhi)潔凈度(du)有(you)較高(gao)要(yao)求，含顆粒狀的(de)介質(zhi)不(bu)(bu)能適用(yong)，如屬(shu)雜質(zhi)須(xu)先濾去。另(ling)外，粘稠(chou)狀介質(zhi)不(bu)(bu)能適用(yong)，而且，特定的(de)產品適用(yong)的(de)介質(zhi)粘度(du)范圍(wei)相對較窄。SMC電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)型(xing)號(hao)多(duo)樣，用(yong)途廣泛(fan)。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)雖有(you)先天不(bu)(bu)足，優(you)(you)點仍(reng)十分突出，所(suo)以(yi)就(jiu)設計成(cheng)多(duo)種(zhong)多(duo)樣的(de)產品，滿足各種(zhong)不(bu)(bu)同的(de)需(xu)求，用(yong)途極為廣泛(fan)。電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)技術的(de)進步也(ye)都是圍(wei)繞著(zhu)如何(he)克服先天不(bu)(bu)足，如何(he)更(geng)(geng)好(hao)地發揮固有(you)優(you)(you)勢(shi)而展開(kai)。

    SMC的(de)(de)(de)質(zhi)(zhi)量(liang)標準是(shi)全球的(de)(de)(de)，SMC（中(zhong)(zhong)(zhong)國(guo)）公司是(shi)中(zhong)(zhong)(zhong)國(guo)氣動行業(ye)(ye)(ye)中(zhong)(zhong)(zhong)第(di)一(yi)家率先通過ISO14001環境管理體系認證的(de)(de)(de)企(qi)(qi)業(ye)(ye)(ye)。曾經(jing)有人對趙(zhao)彤(tong)說，如果(guo)將(jiang)SMC產(chan)品的(de)(de)(de)質(zhi)(zhi)量(liang)降(jiang)(jiang)低(di)一(yi)半、價(jia)(jia)(jia)格(ge)也(ye)降(jiang)(jiang)低(di)一(yi)半，其(qi)(qi)產(chan)品可能在目(mu)前(qian)中(zhong)(zhong)(zhong)國(guo)更有市(shi)場(chang)(chang)。趙(zhao)彤(tong)則將(jiang)產(chan)品分為四(si)類(lei)，即高(gao)質(zhi)(zhi)高(gao)價(jia)(jia)(jia)、高(gao)質(zhi)(zhi)低(di)價(jia)(jia)(jia)、低(di)質(zhi)(zhi)高(gao)價(jia)(jia)(jia)、低(di)質(zhi)(zhi)低(di)價(jia)(jia)(jia)，第(di)三種(zhong)無疑(yi)會被淘汰，第(di)四(si)種(zhong)的(de)(de)(de)市(shi)場(chang)(chang)空(kong)間留給(gei)其(qi)(qi)他競爭對手，高(gao)質(zhi)(zhi)低(di)價(jia)(jia)(jia)是(shi)企(qi)(qi)業(ye)(ye)(ye)、用戶(hu)(hu)永遠追求(qiu)的(de)(de)(de)目(mu)標。SMC絕(jue)不會只為眼(yan)前(qian)的(de)(de)(de)利益，放棄對高(gao)質(zhi)(zhi)量(liang)產(chan)品的(de)(de)(de)追求(qiu)，即進行產(chan)品開(kai)發時不將(jiang)中(zhong)(zhong)(zhong)國(guo)客(ke)戶(hu)(hu)與世界上的(de)(de)(de)其(qi)(qi)他客(ke)戶(hu)(hu)區別對待，而是(shi)始(shi)終采取高(gao)質(zhi)(zhi)量(liang)的(de)(de)(de)市(shi)場(chang)(chang)策略，耐心地等待中(zhong)(zhong)(zhong)國(guo)市(shi)場(chang)(chang)的(de)(de)(de)成熟(shu)，培育市(shi)場(chang)(chang)的(de)(de)(de)成熟(shu)。
