BLR/NRF/NRFE 型热力膨胀阀

描述：

BLR/NRF/ NRFE 系列是新一代热力膨胀阀，它吸收美国ALCO公司的引进技术，可提供多种制冷剂及其各种工况下的充注，能满足冷藏柜，制冰机，除湿机及各种温度范围内的制冷、空调需求，并能和RF系列膨胀阀互换。


特点

◆稳定的过热度调节性能。

◆蒸发温度范围：-40℃至10℃。

◆可提供MOP（马达过载保护）功能。

◆可进口滤网。

◆适用于R22、R502、R134a、R404A、R507等介质。

1.旋下密封螺帽，旋转调节杆。顺时针转动调节杆一圈，过热度增加1.5℃，逆时针转动调节杆一圈，过热度减少1.5℃。出厂过热度设定为3.5℃，静过热度调节范围2~8℃

2.阀的进口接储液筒，出口接蒸发器入口端。感温包的安装应保证感温包充分感受蒸发器出口温度，外平衡管安装位置在感温包附近，从回气管顶部引出。
