比例閥AGMZA-R-20/180/M/PE的構造有哪幾部分

 ATOS廠(chǎng)家AGMZA-R-20/180/M/PE防爆比例溢流閥用于開(kāi)環(huán)壓力控制。它們配備防爆比例螺線(xiàn)管，經(jīng)過(guò)認證，可在潛在爆炸性氣氛的危險環(huán)境中安全操作。

尺寸：10 

最大流量：200升/分鐘

最大壓力：250bar

安裝：任意位置

滯后[最大壓力的%]：≤ 1,5

線(xiàn)性度[最大壓力的%]：≤ 3

重復性[最大壓力的%]：≤ 2


工作原理：

 當系統壓力升高達到整定壓力時(shí)，氣體在導閥密封面處向上頂起導閥的閥芯，使密封面處于開(kāi)啟狀態(tài)，同時(shí)導閥閥腔內的滑閥向上移動(dòng)，封閉導閥閥腔的過(guò)氣通道。主閥閥瓣上方氣室的介質(zhì)經(jīng)由打開(kāi)的導閥密封面排出，使主閥閥瓣上方壓力降低。主閥閥瓣在進(jìn)口壓力的推動(dòng)下打開(kāi)而使系統卸壓。
 當系統壓力降低到一定值時(shí)，導閥閥芯在彈簧的作用下向下回座，導閥密封面關(guān)閉，導閥閥腔的滑閥打開(kāi)，閥腔暢通，系統壓力再次通過(guò)導閥閥腔傳入主閥閥瓣上方氣室，并推動(dòng)主閥閥瓣關(guān)閉
