ASCO阿斯卡電磁閥低價(jià)銷售

ASCO® RED-HAT® –電磁閥主要用于精確控制， 在工商業(yè)應(yīng)用中控制空氣、 燃?xì)狻⑺?、輕油、蒸汽等幾乎所有流體和氣態(tài)物質(zhì)。為了滿足新設(shè)備不斷增長的需要，一些新的相關(guān)產(chǎn)品也被開發(fā)出來，比如氣動(dòng)操作閥，手動(dòng)復(fù)位閥，和智能閥等。ASCO同時(shí)生產(chǎn)制造多種閥，當(dāng)一種標(biāo)準(zhǔn)產(chǎn)品不能*適用新的需要時(shí)，這些閥就可以滿足原始設(shè)備制造商市場的個(gè)性化需求。參照具體 產(chǎn)品介紹可獲得更詳細(xì)資料。 　　1920年，ASCO又有了一次巨大突破，為緊急電源控制開發(fā)出*種自動(dòng)轉(zhuǎn)換開關(guān)。這一產(chǎn)品可以感應(yīng)到停電狀況，將關(guān)鍵電力負(fù)荷從斷電的正常電源中轉(zhuǎn)移到緊急備用電源。如今，ASCO的電源開關(guān)組成的產(chǎn)品用于控制備用電源現(xiàn)場發(fā)電機(jī)，包括關(guān)閉轉(zhuǎn)換調(diào)節(jié)開關(guān)，同時(shí)發(fā)電并降低峰值負(fù)荷， 儲(chǔ)備電力和能源的管理，也用于照明控制和其他電力應(yīng)用。 　　70年代中期， ASCO引進(jìn)了*的壓力和溫度開關(guān)系列，用以滿足多變的工業(yè)應(yīng)用要求。ASCO 三定點(diǎn)壓力和溫度開關(guān)能感應(yīng)各種流體的壓力和溫度。在操作中，它們會(huì)發(fā)出一個(gè)警報(bào)信號(hào)或者關(guān)閉系統(tǒng)。在其他操作中，它們能控制設(shè)備的開啟順序，比如壓縮機(jī)或者電磁閥。 　　1985年，ASCO和JOUCOMATIC合并組建了ASCO/JOUCOMATIC。JOUCOMATIC是法國的氣動(dòng)元件制造商。這些產(chǎn)品包括氣控先導(dǎo)電磁閥，換向控制閥，比例閥和過濾、調(diào)節(jié)、潤滑裝置等。 　　此外，ASCO以幾種不同的品牌來銷售電磁閥產(chǎn)品。這些包括控制易燃介質(zhì)的ASCO/GENERAL CONTROLS®，醫(yī)療市場的ASCO SCIENTIFIC®，較普通場所應(yīng)用的SIRAI ®。所有這些產(chǎn)品都具有如您所期望的于控制閥工業(yè)的高精品質(zhì)和可靠性能。

到目前為止，國內(nèi)外的電磁閥從原理上分為三大類（即：直動(dòng)式、分步直動(dòng)式、先導(dǎo)式），而從閥瓣結(jié)構(gòu)和材料上的不同與原理上的區(qū)別又分為六個(gè)分支小類（直動(dòng)膜片結(jié)構(gòu)、分步膜片結(jié)構(gòu)、先導(dǎo)式膜片結(jié)構(gòu)、直動(dòng)活塞結(jié)構(gòu)、分步活塞結(jié)構(gòu)、先導(dǎo)活塞結(jié)構(gòu)） 。
  （一）、美國ASCO阿斯卡直動(dòng)式電磁閥
  原理：通電時(shí)，電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起，閥門打開；斷電時(shí)，電磁力消失，彈簧力把關(guān)閉件壓在閥座上，閥門關(guān)閉。
  特點(diǎn)：在真空、負(fù)壓、零壓時(shí)能正常工作，但一般通徑不超過25mm。
  （二）、美國ASCO阿斯卡分步直動(dòng)式電磁閥
  原理：它是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理，當(dāng)入口與出口壓差≤0.05Mpa，通電時(shí)，電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起，閥門打開。
  當(dāng)入口與出口壓差>0.05Mpa，通電時(shí)，電磁力先打開先導(dǎo)小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開；斷電時(shí)，先導(dǎo)閥和主閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件，向下移動(dòng)，使閥門關(guān)閉。
  特點(diǎn)：在零壓差或真空、高壓時(shí)亦能可靠工作，但功率較大，要求豎直安裝。
  （三）、美國ASCO阿斯卡先導(dǎo)式電磁閥
  原理：通電時(shí)，電磁力把先導(dǎo)孔打開，上腔室壓力迅速下降，在關(guān)閉件周圍形成上低下高的壓差，推動(dòng)關(guān)閉件向上移動(dòng)，閥門打開；斷電時(shí)，彈簧力把先導(dǎo)孔關(guān)閉，入口壓力通過旁通孔迅速進(jìn)入上腔室在關(guān)閥件周圍形成下低上高的壓差，推動(dòng)關(guān)閉件向下移動(dòng)，關(guān)閉閥門。
  特點(diǎn)：流體壓力范圍上限很高，但必須滿足流體壓差條件

選型要領(lǐng)：
ASCO電磁閥選型首先應(yīng)該依次遵循安全性，可靠性，適用性，經(jīng)濟(jì)性四大原則，其次是根據(jù)六個(gè)方面的現(xiàn)場工況（即管道參數(shù)、流體參數(shù)、壓力參數(shù)、電氣參數(shù)、動(dòng)作方式、特殊要求進(jìn)行選擇）.
選美國*2位2通電磁閥型依據(jù)：
 一、根據(jù)管道參數(shù)選擇電磁閥的：通徑規(guī)格（即DN）、接口方式
1、按照現(xiàn)場管道內(nèi)徑尺寸或流量要求來確定通徑（DN）尺寸.
2、接口方式，一般>DN50要選擇法蘭接口，≤DN50則可根據(jù)用戶需要自由選擇.

二、根據(jù)流體參數(shù)選擇電磁閥的：材質(zhì)、溫度組
1、腐蝕性流體：宜選用耐腐蝕電磁閥和全不銹鋼；食用超凈流體：宜選用食品級(jí)不銹鋼材質(zhì)電磁閥.
2、高溫流體：要選擇采用耐高溫的電工材料和密封材料制造的電磁閥，而且要選擇活塞式結(jié)構(gòu)類型的.
3、流體狀態(tài)：大至有氣態(tài)，液態(tài)或混合狀態(tài)，特別是口徑大于DN25訂貨時(shí)一定要區(qū)分開來.
4、流體粘度：通常在50cSt以下可任意選擇，若超過此值，則要選用高粘度電磁閥.

三、根據(jù)壓力參數(shù)選擇電磁閥的：原理和結(jié)構(gòu)品種
1、公稱壓力：這個(gè)參數(shù)與其它通用閥門的含義是一樣的，是根據(jù)管道公稱壓力來定.
2、工作壓力：如果工作壓力低則必須選用直動(dòng)或分步直動(dòng)式原理；zui低工作壓差在0.04Mpa以上時(shí)直動(dòng)式、分步直動(dòng)式、先導(dǎo)式均可選用.

四、電氣選擇：電壓規(guī)格應(yīng)盡量優(yōu)先選用AC220V、DC24較為方便.

五、根據(jù)持續(xù)工作時(shí)間長短來選擇：常閉、常開、或可持續(xù)通電
1、當(dāng)電磁閥需要長時(shí)間開啟，并且持續(xù)的時(shí)間多余關(guān)閉的時(shí)間應(yīng)選用常開型.
2、要是開啟的時(shí)間短或開和關(guān)的時(shí)間不多時(shí)，則選常閉型.
3、但是有些用于安全保護(hù)的工況，如爐、窯火焰監(jiān)測，則不能選常開的，應(yīng)選可長期通電型.E290A792 E290A846
