介绍了对 H 型、F 型热力膨胀阀和电子膨胀阀所进行的动态响应特性实验,验证了膨胀阀感受过热度的响应近似于一阶惯性延迟环节,给出了响应的延迟和时间常数值以及流量系数关系式。
The dynamic response characteristics of H-type, F-type thermal expansion valve and electronic expansion valve were introduced. The response of the expansion valve to the superheat of the expansion valve was verified to be similar to that of the first-order inertia delay, and the response delay and time constant value And flow coefficient relations.
