美(mei)國PARKER電磁閥主要特點: 1、外漏堵(du)絕,內漏易控,使用安(an)全 內(nei)外(wai)泄(xie)漏(lou)(lou)是危及安全的(de)要(yao)素。其它(ta)自控(kong)(kong)閥(fa)(fa)通常將閥(fa)(fa)桿伸出,由電(dian)(dian)(dian)動(dong)(dong)(dong)、氣動(dong)(dong)(dong)、液動(dong)(dong)(dong)執行機構(gou)控(kong)(kong)制閥(fa)(fa)芯(xin)的(de)轉動(dong)(dong)(dong)或(huo)(huo)移(yi)動(dong)(dong)(dong)。這都要(yao)解決長期動(dong)(dong)(dong)作閥(fa)(fa)桿動(dong)(dong)(dong)密(mi)封(feng)的(de)外(wai)泄(xie)漏(lou)(lou)難題(ti);唯有(you)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)是用(yong)電(dian)(dian)(dian)磁(ci)(ci)力作用(yong)于密(mi)封(feng)在電(dian)(dian)(dian)動(dong)(dong)(dong)調節閥(fa)(fa)隔磁(ci)(ci)套管內(nei)的(de)鐵芯(xin)完成(cheng),不(bu)存在動(dong)(dong)(dong)密(mi)封(feng),所(suo)以外(wai)漏(lou)(lou)易堵(du)絕。電(dian)(dian)(dian)動(dong)(dong)(dong)閥(fa)(fa)力矩控(kong)(kong)制不(bu)易,容易產生內(nei)漏(lou)(lou),甚至拉斷閥(fa)(fa)桿頭部;電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)的(de)結(jie)構(gou)型式容易控(kong)(kong)制內(nei)泄(xie)漏(lou)(lou),直至降為零。所(suo)以,電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)使用(yong)特(te)別安全,尤其適(shi)用(yong)于腐蝕性、有(you)毒或(huo)(huo)高低溫的(de)介(jie)質。 2、系(xi)統簡單,便接電(dian)腦,價格低廉 電(dian)磁閥(fa)本身(shen)結構(gou)簡(jian)單(dan),價格也低(di),比起調節(jie)閥(fa)等(deng)其它種類執行器易于(yu)安裝維護。更顯(xian)著的是所組成的自控系統簡(jian)單(dan)得(de)多(duo),價格要(yao)低(di)得(de)多(duo)。由于(yu)電(dian)磁閥(fa)是開關信號(hao)控制,與工(gong)控計(ji)算(suan)機連接十分方便。在當今電(dian)腦普及,價格大幅下降的時代,電(dian)磁閥(fa)的優(you)勢就(jiu)更加明顯(xian)。 3、動作快遞,功率微小,外形(xing)輕巧(qiao) 電(dian)磁(ci)(ci)閥(fa)(fa)響應時間可以短(duan)至幾個(ge)毫秒(miao),即使是先導式電(dian)磁(ci)(ci)閥(fa)(fa)也可以控制在幾十毫秒(miao)內。由于自成(cheng)回路(lu),比之其(qi)它(ta)自控閥(fa)(fa)反應更靈敏。設計得(de)當的電(dian)磁(ci)(ci)閥(fa)(fa)線(xian)圈功率消(xiao)耗(hao)很(hen)低,屬(shu)節能產品;還可做到只需觸(chu)發動作,自動保持閥(fa)(fa)位,平時一點也不耗(hao)電(dian)。電(dian)磁(ci)(ci)閥(fa)(fa)外(wai)形(xing)尺寸小(xiao),既節省(sheng)空間,又輕巧美觀。 4、調節精度受限,適用介質(zhi)受限 電磁閥通常(chang)只有開關兩種狀態,閥芯只能(neng)處于兩個極限位置,不能(neng)連續調(diao)節(jie),所以調(diao)節(jie)精度還(huan)受到一定限制。 電磁閥對(dui)(dui)介質(zhi)潔(jie)凈度有(you)較(jiao)高(gao)要(yao)求,含(han)顆粒狀的介質(zhi)不(bu)能適(shi)用(yong),如(ru)屬雜質(zhi)須先(xian)濾去。另外(wai),粘(zhan)稠狀介質(zhi)不(bu)能適(shi)用(yong),而(er)且,特(te)定的產品適(shi)用(yong)的介質(zhi)粘(zhan)度范圍相對(dui)(dui)較(jiao)窄。 5、型號(hao)多樣,用途廣(guang)泛 電磁(ci)閥雖有先天不足,優點仍(reng)十分突出,所以就設計成(cheng)多(duo)種多(duo)樣的產品,滿足各種不同(tong)的需求,用途極為廣泛。電磁(ci)閥技術的進步也都是圍繞著如(ru)何(he)克服先天不足,如(ru)何(he)更好地發揮固有優勢而展開。 美國PARKER電磁閥型號: VUVB-S-M42-AZD-QX-1C1 VUVB-S-M42-AZD-Q6-1C1 VG35-ERS VE83-A-S-5 VE42-A-S-5-B00 VE03-ESP002C2 VABM-B6-E-G12-7-2 VABM-B6-E-G12-7 UNS-16001-613 TS38-20A-0-N-24DG SZ4504017 SZ4503016 SV58-25-0-P-24DG SV58-25-0-N-24DG SV38-38-0-N-24DG SV-2-1144-2 SIE311-IP-SD2-D4 R900021389 PVL-C1723 PVL-C121419 PVL-C112419 PVL-C111419 PVD-B1414 PVA-P122 PVA-F102BX02 PVA-F102B PRS-D10 塊(kuai) PHV510S-6-220V-L PHS541D-15-220V-D PHS541D-15 PHS520S-8-220V-DL PHS520S-8-110V-DL PHS520S-8 PHS520D-8-L PH-BK-06 PES5 DIN PEC5-24V-D-1 PEC5-24V-D PEC5-220V-D PEC5-110V-D PEC5-110V PCG5V6CEMUH711 PB61949-070 PB60649-050 PB60549-050 PADA1007-AA-BB P4Q-CA16 P4Q-CA14 P3ZRA1CBPPN P3ZRA1BBPPN P3YRA18BPPN P2N-YS514SD P2N-JS516SD P2FCA457 P210D9 KVE11143 KMEB-1-24-5-LED |
