ASCO電磁閥是哪個國家生產的?要求必須水平安裝。 先導式電磁閥: 原理:通電時,電磁力把先導孔打開,上腔室壓力迅速下降,在關閉件周圍形成上低下高的壓差,流體壓力推動關閉件向上移動,閥門打開;斷電時,彈簧力把先導孔關閉,入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差,流體壓力推動關閉件向下移動,關閉閥門。
二位三通電磁閥由閥體和電磁線圈兩部分組成,是自帶橋式整流電路,并帶過電壓、過電流安全保護的直動式結構绱歐А?br> 系統中工作狀態一:電磁閥線圈不通電。此時,電磁閥鐵芯在回復彈簧的作用下靠在雙管端,關閉雙管端出口,單管端出口處于開啟狀態,制冷劑從電磁閥單管端出口管流向冷藏室蒸發器、冷凍室蒸發器流回壓縮機,實現制冷循環。
