VICKERS/威格(ge)士電磁閥(fa)主要(yao)特點

1、外漏(lou)堵絕，內漏(lou)易控，使用安全

內外泄(xie)漏(lou)是危及安(an)全(quan)的(de)要素。其它自控(kong)閥(fa)(fa)通常將(jiang)閥(fa)(fa)桿伸出，由電(dian)動(dong)(dong)(dong)、氣(qi)動(dong)(dong)(dong)、液動(dong)(dong)(dong)執(zhi)行機構控(kong)制閥(fa)(fa)芯(xin)的(de)轉動(dong)(dong)(dong)或(huo)移動(dong)(dong)(dong)。這(zhe)都(dou)要解決長期動(dong)(dong)(dong)作閥(fa)(fa)桿動(dong)(dong)(dong)密封(feng)的(de)外泄(xie)漏(lou)難題(ti)；唯(wei)有電(dian)磁閥(fa)(fa)是用(yong)電(dian)磁力(li)作用(yong)于密封(feng)在電(dian)動(dong)(dong)(dong)調(diao)節閥(fa)(fa)隔磁套(tao)管內的(de)鐵(tie)芯(xin)完(wan)成(cheng)，不存在動(dong)(dong)(dong)密封(feng)，所以(yi)外漏(lou)易堵絕。電(dian)動(dong)(dong)(dong)閥(fa)(fa)力(li)矩控(kong)制不易，容(rong)易產生內漏(lou)，甚至拉斷閥(fa)(fa)桿頭部；電(dian)磁閥(fa)(fa)的(de)結構型式(shi)容(rong)易控(kong)制內泄(xie)漏(lou)，直(zhi)至降為(wei)零(ling)。所以(yi)，電(dian)磁閥(fa)(fa)使(shi)用(yong)特別安(an)全(quan)，尤其適用(yong)于腐(fu)蝕(shi)性(xing)、有毒(du)或(huo)高低溫(wen)的(de)介(jie)質。

2、系統簡單(dan)，便接電腦，價格(ge)低廉

VICKERS電(dian)磁閥本(ben)身結構(gou)簡單(dan)，價格也(ye)低(di)，比起(qi)調節(jie)閥等其它(ta)種類執行器(qi)易(yi)于(yu)安裝維護。更(geng)顯(xian)著的(de)是所組成的(de)自控(kong)系統簡單(dan)得多，價格要低(di)得多。由于(yu)電(dian)磁閥是開關信號控(kong)制，與工控(kong)計(ji)算機連接十(shi)分方便。在當今電(dian)腦普及，價格大幅下降的(de)時(shi)代，電(dian)磁閥的(de)優勢就(jiu)更(geng)加(jia)明顯(xian)。

3、動(dong)作(zuo)快遞，功率(lv)微(wei)小，外形輕巧(qiao)

VICKERS電磁(ci)閥(fa)響應時(shi)間可以短至幾(ji)(ji)個(ge)毫(hao)秒(miao)(miao)，即使是先導式電磁(ci)閥(fa)也可以控制在(zai)幾(ji)(ji)十毫(hao)秒(miao)(miao)內(nei)。由于(yu)自(zi)(zi)成回(hui)路(lu)，比之其它自(zi)(zi)控閥(fa)反應更靈敏。設計得當的電磁(ci)閥(fa)線圈功率消耗(hao)很低，屬節(jie)能產品；還可做到只需觸(chu)發動(dong)作，自(zi)(zi)動(dong)保持(chi)閥(fa)位，平時(shi)一點(dian)也不耗(hao)電。電磁(ci)閥(fa)外形(xing)尺(chi)寸小，既節(jie)省(sheng)空(kong)間，又輕(qing)巧(qiao)美觀。

4、調節精度(du)受限，適(shi)用介質(zhi)受限

VICKERS電磁(ci)閥(fa)通常只有開關兩(liang)種狀(zhuang)(zhuang)態，閥(fa)芯只能(neng)(neng)處于兩(liang)個(ge)極限(xian)位(wei)置(zhi)，不能(neng)(neng)連續調(diao)(diao)節(jie)(jie)，所以(yi)調(diao)(diao)節(jie)(jie)精度還受到一(yi)定限(xian)制。電磁(ci)閥(fa)對(dui)(dui)介(jie)質潔凈度有較(jiao)高要(yao)求，含顆粒(li)狀(zhuang)(zhuang)的介(jie)質不能(neng)(neng)適(shi)用，如屬(shu)雜質須(xu)先濾去。另外，粘稠(chou)狀(zhuang)(zhuang)介(jie)質不能(neng)(neng)適(shi)用，而且，特定的產品適(shi)用的介(jie)質粘度范圍相對(dui)(dui)較(jiao)窄。

5、型號多(duo)樣，用途廣泛

電磁閥雖有先天不足，優點仍十分突出，所以就設計成多種多樣的產品，滿足各種不同的需求，用途極為廣泛。電磁閥技術的進步也都是圍繞著如何克服先天不足，如何更好地發揮固有優勢而展開。威格士VICKERS電磁閥優勢貨源圖如下：
