進(jìn)口先導(dǎo)式電磁閥
德國(guó)LIT進(jìn)口先導(dǎo)式電磁閥有幾點(diǎn)特點(diǎn)（1）動(dòng)作快，功率小，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(dòng)作，自動(dòng)保持閥位，平時(shí)一點(diǎn)也不耗電。（2）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)，（德國(guó)力特試圖突破，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(duì)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(duì)較窄。（3）型號(hào)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(shì)而展開。
Germany LIT imports pilot solenoid valve There are several characteristics of （1） the action is fast and small power, lightweight form factor. Solenoid valve response time can be as short as a few milliseconds, even if it is a pilot-type solenoid valve can also be controlled to within tens of milliseconds. Self-loops, other than the automatic control valve response is more sensitive. Properly designed solenoid valve coil power consumption is very low, an energy-saving products; trigger actions can also be done simply, and automatically maintain valve position, usually is not consumable. （2） to adjust the accuracy is limited, restricted Applicable medium. The solenoid valve is usually only switch the two states, the spool only at the two extreme positions, can not be adjusted continuously, （German special forces tried to break through, but also in the experimental trial stage） regulation accuracy is also subject to certain restrictions. Solenoid valve with higher requirements for media cleanliness, containing granular media can not be applied, the case must first filter out impurities. In addition, the viscous medium is not applicable, and particular product is suitable for medium viscosity range is relatively narrow. （3） Model diverse, wide range of uses. Although the solenoid valve deficiencies, the advantages still very prominent, so a wide variety of products designed to meet the various needs, extremely versatile. Solenoid valve technology advances are also around how to overcome the inherent weaknesses, and how to better play to the inherent advantages and expand.
