帶集成式放大板比例閥
首先，比例閥必須有一個(gè)配套的放大器，它接受來(lái)自于計(jì)算機(jī)，或者PLC，或者電位器（滑動(dòng)變阻器）的控制信號(hào)，把0-20毫安微弱的信號(hào)放大到0-800毫安。計(jì)算機(jī)的信號(hào)太弱了。
然后，放大器把放大的信號(hào)傳送到電磁閥度，電磁閥依據(jù)傳來(lái)的信號(hào)大小，克服彈簧力，調(diào)節(jié)推桿的行程，輸出流量大約知1升/分鐘,壓力隨信號(hào)變化的控制油。
再后，控制油到達(dá)主閥芯的兩端，依據(jù)不同的壓力，推動(dòng)閥芯移動(dòng)相應(yīng)的行程，因?yàn)殚y芯本身有錐度的臺(tái)階，與閥體組合，不同的行程得到不道同的過(guò)流面積，再入版口壓力穩(wěn)定的情況下，得到不同的流量。終實(shí)現(xiàn)比例功能。
比例閥是由計(jì)算機(jī)（或其他），放大器，比例電磁鐵，錐度臺(tái)階的閥芯，入口壓力補(bǔ)償閥（單聯(lián)可以不要），梭閥，內(nèi)置卸荷閥（把多余的流量送回油箱）等構(gòu)成的一個(gè)體權(quán)系。才能真正實(shí)現(xiàn)比例功能。
