两种常见形式是固定节流阀式或节流管式，以及节流膨胀阀。
Two common types are the fixed orifice, or the orifice tube, and the thermostatic expansion valve.
2
最经常的情况是，在膨胀阀处水分变成冰儿阻碍了制冷剂的流动。
In most cases the refrigerant flow is being obstructed as moisture turns to ice at the expansion valve.

分析热力膨胀阀和蒸发器调节系统的稳定性，它直接影响着制冷效率和运行安全。
This paper describes the stability of control loop consisting of refrigeration evaporator and thermostatic expansion valve. It may directly influence refrigerating efficiency and operation safety.

膨胀阀
膨胀阀是制冷系统中的一个重要部件，一般安装于储液筒和蒸发器之间。膨胀阀使中温高压的液体制冷剂通过其节流成为低温低压的湿蒸汽，然后制冷剂在蒸发器中吸收热量达到制冷效果，膨胀阀通过蒸发器末端的过热度变化来控制阀门流量，防止出现蒸发器面积利用不足和敲缸现象。
