美(mei)國PARKER電(dian)磁(ci)閥主(zhu)要特點: 1、外漏堵絕,內漏易控,使用安全 內外泄(xie)(xie)漏(lou)(lou)是危及(ji)安全的(de)(de)(de)要素(su)。其(qi)它自控(kong)(kong)閥(fa)通常將閥(fa)桿(gan)(gan)伸出(chu),由電(dian)(dian)動(dong)(dong)(dong)(dong)、氣(qi)動(dong)(dong)(dong)(dong)、液(ye)動(dong)(dong)(dong)(dong)執行機構(gou)控(kong)(kong)制閥(fa)芯的(de)(de)(de)轉動(dong)(dong)(dong)(dong)或移動(dong)(dong)(dong)(dong)。這都要解決長期動(dong)(dong)(dong)(dong)作閥(fa)桿(gan)(gan)動(dong)(dong)(dong)(dong)密封(feng)的(de)(de)(de)外泄(xie)(xie)漏(lou)(lou)難題;唯有電(dian)(dian)磁(ci)閥(fa)是用電(dian)(dian)磁(ci)力作用于(yu)密封(feng)在(zai)電(dian)(dian)動(dong)(dong)(dong)(dong)調節閥(fa)隔磁(ci)套管內的(de)(de)(de)鐵芯完(wan)成,不存(cun)在(zai)動(dong)(dong)(dong)(dong)密封(feng),所以外漏(lou)(lou)易堵絕。電(dian)(dian)動(dong)(dong)(dong)(dong)閥(fa)力矩控(kong)(kong)制不易,容易產生內漏(lou)(lou),甚至拉斷閥(fa)桿(gan)(gan)頭部;電(dian)(dian)磁(ci)閥(fa)的(de)(de)(de)結(jie)構(gou)型式容易控(kong)(kong)制內泄(xie)(xie)漏(lou)(lou),直至降為零(ling)。所以,電(dian)(dian)磁(ci)閥(fa)使(shi)用特別安全,尤(you)其(qi)適用于(yu)腐蝕性、有毒(du)或高低溫的(de)(de)(de)介質。 2、系統簡單,便(bian)接(jie)電(dian)腦(nao),價格低廉 電磁閥(fa)本身結構簡(jian)單(dan),價(jia)(jia)格也(ye)低(di),比起調節閥(fa)等(deng)其它種類執行(xing)器易于(yu)(yu)安裝(zhuang)維護。更顯著的是所組成的自控系統簡(jian)單(dan)得(de)(de)多,價(jia)(jia)格要(yao)低(di)得(de)(de)多。由于(yu)(yu)電磁閥(fa)是開(kai)關(guan)信號控制,與工控計算(suan)機連接十分方便(bian)。在當今電腦(nao)普及,價(jia)(jia)格大幅下降的時代,電磁閥(fa)的優勢就更加明顯。 3、動作快遞(di),功率微小,外(wai)形(xing)輕巧 電(dian)磁(ci)閥(fa)響應時(shi)(shi)間可(ke)以短至幾(ji)(ji)個毫秒(miao),即使是先導式電(dian)磁(ci)閥(fa)也可(ke)以控制在幾(ji)(ji)十毫秒(miao)內(nei)。由于自成回路,比之其它自控閥(fa)反應更靈(ling)敏(min)。設計得當的電(dian)磁(ci)閥(fa)線圈(quan)功率消耗很低,屬節能產品;還(huan)可(ke)做到只需觸發動作,自動保持閥(fa)位,平(ping)時(shi)(shi)一點也不耗電(dian)。電(dian)磁(ci)閥(fa)外形(xing)尺寸小,既節省空間,又輕巧美觀(guan)。 4、調節精度受限(xian),適用介(jie)質(zhi)受限(xian) 電磁(ci)閥通(tong)常只(zhi)有開(kai)關(guan)兩種狀態(tai),閥芯只(zhi)能處于兩個極限位置,不(bu)能連續調節,所以調節精度還受(shou)到一(yi)定限制。 電磁閥對(dui)介(jie)質潔凈度有較(jiao)高要求,含顆粒(li)狀的介(jie)質不能(neng)適用,如屬雜質須先濾去。另外,粘(zhan)稠狀介(jie)質不能(neng)適用,而且,特定的產品適用的介(jie)質粘(zhan)度范圍相對(dui)較(jiao)窄。 5、型號(hao)多樣(yang),用(yong)途(tu)廣泛 電磁閥雖(sui)有先天(tian)不(bu)足(zu),優點仍十分突(tu)出,所(suo)以就設(she)計成多種多樣的(de)產品,滿(man)足(zu)各種不(bu)同的(de)需求,用途極(ji)為廣泛。電磁閥技術的(de)進步也都是圍繞著如何克服先天(tian)不(bu)足(zu),如何更好地發揮固(gu)有優勢(shi)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 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 |
