詢價(jià):陳
廣泛應(yīng)用于鋼鐵、冶金、鋁行業(yè)、石油化工、航天、船舶制造、煤炭、水泥、電力、汽車、工程機(jī)械、食品、藥業(yè)、林業(yè)、紡織、皮革、造紙等行業(yè)領(lǐng)域
電磁閥應(yīng)用十分廣泛,而使用時(shí)情況卻千差萬別,增強(qiáng)通用性能降低制造、購銷、存貯、安裝、維護(hù)的成本,近年來這方面邁出了大步。
(1)響應(yīng)時(shí)間可調(diào)
給出電信號到閥芯動作完成的時(shí)間稱為響應(yīng)時(shí)間。不同場合希望開關(guān)速度不同,有四種組合:快開快關(guān)----用于快速反應(yīng)系統(tǒng);快開慢關(guān)----用于防止水錘;慢開快關(guān)---用于緩啟急斷; 慢開慢關(guān)一一用于平穩(wěn)過渡。ZDF 多功能電磁閥可方使地調(diào)整于任一狀態(tài),應(yīng)用十分靈活。
(2)擴(kuò)展介質(zhì)適用范固。
電磁閥與其它自控閥不同在于介質(zhì)粘度適用范圍較窄,所以空氣、水、蒸汽、油等介質(zhì)對于先導(dǎo)型電磁閥其結(jié)構(gòu)參數(shù)是不同的;一般地說是不能通用的。而ZDF多功能電磁閥只用一顆小螺釘,卻做到了氣、水、油的通用,而且還使油的粘度適用范圍大大加寬,深受歡迎。
(3)開度可調(diào)與于動兼窯
電磁閥在使用時(shí)常常還希望它兼具手動功能,作為停電或故障時(shí)備用。
一般手動裝置只能手動開閥或手動關(guān)閥,二者齊備的稱*手動。手動裝置還能對閥門開度進(jìn)行預(yù)置,一般手動只能對閥的zui大或zui小開度進(jìn)行預(yù)置,而*手動能分別對zui大或zui小開度進(jìn)行預(yù)置。ZDF多功能電磁閥屬*手動類。其它型號電磁閥根據(jù)需要可帶簡單的一般手動裝置。

電磁閥是用電磁的效應(yīng)進(jìn)行控制,主要的控制方式由繼電器控制。這樣,電磁閥可以配合不同的電路來實(shí)現(xiàn)預(yù)期的控制,而控制的精度和靈活性都能夠保證。
電磁閥的主要特點(diǎn)
(1)外漏堵絕,內(nèi)漏易控,使用安全。內(nèi)外泄漏是危及安全的要素。其它自控閥通常將閥桿伸出,由電動、氣動、液動執(zhí)行機(jī)構(gòu)控制閥芯的轉(zhuǎn)動或移動。這都要解決*動作閥桿動密封的外泄漏難題;唯有電磁閥是用電磁力作用于密封在隔磁套管內(nèi)的鐵芯完成,不存在動密封,所以外漏易堵絕。電動閥力矩控制不易,容易產(chǎn)生內(nèi)漏,甚至拉斷閥桿頭部;電磁閥的結(jié)構(gòu)型式容易控制內(nèi)泄漏,直至降為零。所以,電磁閥使用特別安全,尤其適用于腐蝕性、有毒或高低溫的介質(zhì)。
(2)系統(tǒng)簡單,便接電腦,低謙。電磁閥本身結(jié)構(gòu)簡單,價(jià)低,比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護(hù)。更顯著的是所組成的自控系統(tǒng)簡單得多,要低得多。由于電磁閥是開關(guān)信號控制,與工控計(jì)算機(jī)連接十分方便。在當(dāng)今電腦普及,大幅下降的時(shí)代,電磁閥的優(yōu)勢就更加明顯。
(3)動作快遞,功率微小,外形輕巧。電磁閥響應(yīng)時(shí)間可以短至幾個(gè)毫秒,即使是先導(dǎo)式電磁閥也可以控制在幾十毫秒內(nèi)。由于自成回路,比之其它自控閥反應(yīng)更靈敏。設(shè)計(jì)得當(dāng)?shù)碾姶砰y線圈功率消耗很低,屬節(jié)能產(chǎn)品;還可做到只需觸發(fā)動作,自動保持閥位,平時(shí)一點(diǎn)也不耗電。電磁閥外形尺寸小,既節(jié)省空間,又輕巧美觀。
(4)調(diào)節(jié)精度受限,適用介質(zhì)受限。電磁閥通常只有開關(guān)兩種狀態(tài),閥芯只能處于兩個(gè)極限位置,不能連續(xù)調(diào)節(jié),(力圖突破的新構(gòu)思不少,但還都處于試驗(yàn)試用階段)所以調(diào)節(jié)精度還受到一定限制。電磁閥對介質(zhì)潔凈度有較高要求,含顆粒狀的介質(zhì)不能適用,如屬雜質(zhì)須先濾去。另外,粘稠狀介質(zhì)不能適用,而且,特定的產(chǎn)品適用的介質(zhì)粘度范圍相對較窄。
(5)型號多樣,用途廣泛。電磁閥雖有先天不足,優(yōu)點(diǎn)仍十分突出,所以就設(shè)計(jì)成多種多樣的產(chǎn)品,滿足各種不同的需求,用途極為廣泛。電磁閥技術(shù)的進(jìn)步也都是圍繞著如何克服先天不足,如何更好地發(fā)揮固有優(yōu)勢而展開。R900341002 SCA32AZ1X/M
