求翻译：膨胀阀感温筒漏气，正常情况下膨胀阀用嘴吹其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, blowing its entrance to the expansion valve will be ventilated through the mouth of 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 blowing the entrance will be submerged, if a temperature and the phenomenon, or expansion valve leaks, there is no aeration plug the phenomenon is occurring

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

Expanding gate valve heat tube air leakage, normally expansion valve with mouth ventilation have their entrance, if heat tube air leakage or expansion valve plug is no ventilation phenomenon

Expansion valve leakage of heat tube, normally expansion valve with mouth-blown its entrance will be fitted with, if the heat tube air leakage, or expansion valve plug, there is no ventilation
