隨著國內(nèi)工業(yè)的快速發(fā)展，直接促使燃?xì)鉁p壓閥的普遍運(yùn)用，尤其是在治金行業(yè)還有就是石油化工等領(lǐng)域的使用，尤其是燃?xì)獗壤y穩(wěn)定的性能還有質(zhì)量的可靠性在行業(yè)競爭中顯得越來越重要了。因為燃?xì)獗壤y在工作中的好壞是直接能夠影響到自動控制的過程。在工業(yè)液壓領(lǐng)域中，隨著電液比例控制技術(shù)的發(fā)展，比例閥產(chǎn)品的種類和性能在發(fā)展變化著，高響應(yīng)比例閥已接近伺服閥性能，相應(yīng)的不同性能的比例閥的名詞和分類也有許多變化，這導(dǎo)致了比例閥產(chǎn)品市場上的名詞分類及解釋各不相同，產(chǎn)生了應(yīng)用混淆，已影響對比例閥名詞的規(guī)范性問題。近些年來，IOS標(biāo)準(zhǔn)及國家標(biāo)準(zhǔn)已頒布一系列標(biāo)準(zhǔn)涉及有關(guān)比例閥名詞，這些標(biāo)準(zhǔn)名詞與市場流行的習(xí)慣有所不同，因此，需根據(jù)國家標(biāo)準(zhǔn)或國際標(biāo)準(zhǔn)名詞術(shù)語進(jìn)行規(guī)范，正確認(rèn)識理解這些比例閥名詞及含義。
