burkert6223先導(dǎo)式比例閥
詳細(xì)說下比例閥結(jié)構(gòu)及工作原理:以晶極三級管為例:電液比例閥是閥內(nèi)比例電磁鐵輸入電壓信號產(chǎn)生相應(yīng)動作,使工作閥閥芯產(chǎn)生位移,閥口尺寸發(fā)生改變并以此完成與輸入電壓成比例壓力、流量輸出元件。閥芯位移也可以以機(jī)械、液壓或電形式進(jìn)行反饋。電液比例閥具有形式種類多樣、容易組成使用電氣及計算機(jī)控制各種電液系統(tǒng)、控制精度高、安裝使用靈活以及抗污染能力強(qiáng)等多方面優(yōu)點(diǎn)

Electro-hydraulic proportional valve is a valve in the input voltage signal proportional electromagnetic valve is a corresponding action, make the job displacement of valve core, valve opening size change and finish with the input voltage is proportional to the pressure and flow output element. Valve core displacement can also be feedback in mechanical, hydraulic or electrical form. Electro-hydraulic proportional valve has the form of species diversity, easy to use all kinds of electrical and computer control electro-hydraulic system, high control precision, easy to install and use flexible and strong ability to resist pollution advantages in many aspects
