建筑給排水知識：日本SMC電磁閥性能特點概述

    SMC電(dian)磁(ci)閥(fa)的(de)(de)主要特點電(dian)磁(ci)閥(fa)外漏堵(du)絕(jue)，內漏易(yi)(yi)控(kong)，使用(yong)(yong)安(an)全。內外泄(xie)漏是危(wei)及安(an)全的(de)(de)要素。其它自控(kong)閥(fa)通常將閥(fa)桿(gan)伸出，由電(dian)動(dong)(dong)、氣動(dong)(dong)、液動(dong)(dong)執行機(ji)構控(kong)制(zhi)閥(fa)芯的(de)(de)轉動(dong)(dong)或移動(dong)(dong)。這都(dou)要解決(jue)長期(qi)動(dong)(dong)作(zuo)閥(fa)桿(gan)動(dong)(dong)密(mi)封的(de)(de)外泄(xie)漏難(nan)題;唯(wei)有電(dian)磁(ci)閥(fa)是用(yong)(yong)電(dian)磁(ci)力作(zuo)用(yong)(yong)于(yu)密(mi)封在電(dian)動(dong)(dong)調(diao)節閥(fa)隔(ge)磁(ci)套(tao)管內的(de)(de)鐵芯完成，不(bu)存在動(dong)(dong)密(mi)封，所(suo)以外漏易(yi)(yi)堵(du)絕(jue)。電(dian)動(dong)(dong)閥(fa)力矩控(kong)制(zhi)不(bu)易(yi)(yi)，容易(yi)(yi)產生內漏，甚至拉斷閥(fa)桿(gan)頭(tou)部(bu);電(dian)磁(ci)閥(fa)的(de)(de)結構型式(shi)容易(yi)(yi)控(kong)制(zhi)內泄(xie)漏，直至降為零(ling)。所(suo)以，電(dian)磁(ci)閥(fa)使用(yong)(yong)特別安(an)全，尤其適用(yong)(yong)于(yu)腐(fu)蝕性、有毒或高低溫的(de)(de)介質(zhi)。

    SMC電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)系(xi)統簡單(dan)(dan)，便接電(dian)(dian)(dian)(dian)(dian)(dian)腦，價(jia)格(ge)低(di)謙。電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)本身結構簡單(dan)(dan)，價(jia)格(ge)也(ye)低(di)，比起調(diao)節(jie)(jie)(jie)閥(fa)(fa)等其它(ta)種類執行器易于安(an)裝維護(hu)。更(geng)顯(xian)著(zhu)的(de)(de)是(shi)所組成(cheng)的(de)(de)自(zi)控(kong)系(xi)統簡單(dan)(dan)得(de)多，價(jia)格(ge)要低(di)得(de)多。由于電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)是(shi)開關信號(hao)控(kong)制(zhi)，與工控(kong)計算機連(lian)接十分方便。在當今電(dian)(dian)(dian)(dian)(dian)(dian)腦普及(ji)，價(jia)格(ge)大幅(fu)下降的(de)(de)時代，電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)的(de)(de)優勢就更(geng)加明(ming)顯(xian)。SMC電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)動(dong)作快遞，功率微小，外(wai)(wai)形輕(qing)巧(qiao)。電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)響(xiang)應(ying)(ying)時間(jian)(jian)可(ke)以短至(zhi)幾個毫秒，即使是(shi)先導(dao)式電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)也(ye)可(ke)以控(kong)制(zhi)在幾十毫秒內。由于自(zi)成(cheng)回路，比之(zhi)其它(ta)自(zi)控(kong)閥(fa)(fa)反應(ying)(ying)更(geng)靈敏。設計得(de)當的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)線圈功率消耗很低(di)，屬(shu)節(jie)(jie)(jie)能產品(pin);還(huan)可(ke)做到只需觸發(fa)動(dong)作，自(zi)動(dong)保(bao)持閥(fa)(fa)位，平(ping)時一點也(ye)不(bu)(bu)(bu)耗電(dian)(dian)(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)外(wai)(wai)形尺寸小，既節(jie)(jie)(jie)省空間(jian)(jian)，又輕(qing)巧(qiao)美觀。電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)調(diao)節(jie)(jie)(jie)精度(du)受(shou)限(xian)(xian)(xian)，適用介(jie)(jie)質(zhi)受(shou)限(xian)(xian)(xian)。電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)通常只有(you)開關兩種狀態，閥(fa)(fa)芯只能處于兩個極限(xian)(xian)(xian)位置，不(bu)(bu)(bu)能連(lian)續調(diao)節(jie)(jie)(jie)，（力圖突破的(de)(de)新(xin)構思不(bu)(bu)(bu)少，但(dan)還(huan)都(dou)處于試驗(yan)試用階段）所以調(diao)節(jie)(jie)(jie)精度(du)還(huan)受(shou)到一定限(xian)(xian)(xian)制(zhi)。SMC電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)對介(jie)(jie)質(zhi)潔凈度(du)有(you)較高要求，含顆(ke)粒狀的(de)(de)介(jie)(jie)質(zhi)不(bu)(bu)(bu)能適用，如屬(shu)雜質(zhi)須先濾(lv)去(qu)。另外(wai)(wai)，粘稠(chou)狀介(jie)(jie)質(zhi)不(bu)(bu)(bu)能適用，而且，特定的(de)(de)產品(pin)適用的(de)(de)介(jie)(jie)質(zhi)粘度(du)范(fan)圍相對較窄。SMC電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)型(xing)號(hao)多樣(yang)，用途廣泛(fan)。電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)雖有(you)先天不(bu)(bu)(bu)足(zu)，優點仍十分突出，所以就設計成(cheng)多種多樣(yang)的(de)(de)產品(pin)，滿足(zu)各種不(bu)(bu)(bu)同的(de)(de)需求，用途極為廣泛(fan)。電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)技術的(de)(de)進步也(ye)都(dou)是(shi)圍繞著(zhu)如何克服(fu)先天不(bu)(bu)(bu)足(zu)，如何更(geng)好地發(fa)揮固(gu)有(you)優勢而展開。

    SMC的質(zhi)量標準是(shi)(shi)全(quan)球的，SMC（中(zhong)國(guo)）公司是(shi)(shi)中(zhong)國(guo)氣動行(xing)業中(zhong)第一(yi)家率(lv)先通過ISO14001環境管理體(ti)系認證的企(qi)業。曾經(jing)有(you)人對趙(zhao)彤說(shuo)，如果將SMC產(chan)品(pin)的質(zhi)量降低一(yi)半、價格也降低一(yi)半，其產(chan)品(pin)可能在目前(qian)(qian)中(zhong)國(guo)更有(you)市(shi)場(chang)。趙(zhao)彤則將產(chan)品(pin)分為四(si)類，即(ji)高(gao)質(zhi)高(gao)價、高(gao)質(zhi)低價、低質(zhi)高(gao)價、低質(zhi)低價，第三種無疑會(hui)被淘(tao)汰(tai)，第四(si)種的市(shi)場(chang)空間留給(gei)其他競(jing)爭對手，高(gao)質(zhi)低價是(shi)(shi)企(qi)業、用戶(hu)永遠追求(qiu)的目標。SMC絕不會(hui)只為眼前(qian)(qian)的利益，放棄對高(gao)質(zhi)量產(chan)品(pin)的追求(qiu)，即(ji)進(jin)行(xing)產(chan)品(pin)開發時不將中(zhong)國(guo)客戶(hu)與世界(jie)上(shang)的其他客戶(hu)區別對待，而(er)是(shi)(shi)始(shi)終采取(qu)高(gao)質(zhi)量的市(shi)場(chang)策(ce)略，耐心地(di)等待中(zhong)國(guo)市(shi)場(chang)的成熟，培育市(shi)場(chang)的成熟。
