求翻译：膨胀阀感温筒漏气，在正常情况下，膨胀阀用嘴吹它的入口处会有通气的现象，如果感温筒漏气，或膨胀阀堵塞，则没有通气的现象发生是什么意思？

Thermal expansion valve cylinder leakage, under normal circumstances, the expansion valve mouth ventilation will blow it at the entrance to the phenomenon, if the temperature tube leak, or expansion valve blockage, there is no ventilation of the phenomenon

thermal expansion valve and gas leakage, under normal circumstances, Expansion Valve mouth blown it at the entrance of the phenomenon will be submerged, if a temperature and gas leakage, or expansion valve plug the phenomenon occurred, there is no aeration

The expansion valve feeling warm tube leaks air, in the normal condition, the expansion valve blows its entrance with the mouth to be able to have the ventilation phenomenon, if feels the warm tube to leak air, or expansion valve jamming, then does not have the ventilation phenomenon to occur

Expansion valve heat tube air leakage, under normal circumstances, expansion valve with mouth-blown its entrance is fitted with, if the heat tube air leakage, or expansion valve plug, there is no ventilation

Expansion valve heat tube air leakage, under normal circumstances, expansion valve with mouth-blown its entrance is fitted with, if the heat tube air leakage, or expansion valve plug, there is no ventilation
