電磁閥鐵芯在回復(fù)彈簧的作用下靠在雙管端,關(guān)閉雙管端出口,單管端出口處于開啟狀態(tài),制冷劑從電磁閥單管端出口管流向冷藏室蒸發(fā)器、冷凍室蒸發(fā)器流回壓縮機(jī),實現(xiàn)制冷循環(huán)。使泵輸出流量與系統(tǒng)實際需要流量相等,無溢流損失,實現(xiàn)了節(jié)能。壓力補(bǔ)償是提高閥控制性能而采取一種保證措施。將閥口后負(fù)載壓力引入壓力補(bǔ)償閥,壓力補(bǔ)償閥對閥口前壓力進(jìn)行調(diào)整使閥口前后壓差為常值,這樣節(jié)流口流量調(diào)節(jié)特性流經(jīng)閥口流量大小就只與該閥口開度有關(guān),而不受負(fù)載壓力影響。

Pressure compensation is a guarantee measure to improve valve control performance. Introducing pressure valve mouth after load pressure compensation valve, pressure compensation valve for pressure adjusting valve mouth before the pressure difference before and after the valve port is constant, so the throttling mouth flow control characteristics through the valve port flow size is only related to the valve opening, and is not affected by load pressure.
