Zusammenfassung:	The invention discloses a venting and filtering combined valve, comprising a venting part and a filtering part from up to down. The venting and filtering combined valve is characterized in that the venting part is an automatic venting valve; the filtering part comprises a tubular shell, wherein the top end of the shell is in spiral connection with the automatic venting valve; one side of the shell, close to the top end of the shell, is provided with a water inlet; the bottom end of the shell is provided with a water outlet; a filter screen supporting frame is arranged inside the shell; and a filter screen barrel is arranged inside the filter screen supporting frame. By virtue of the venting and filtering combined valve, the venting and filtering functions in water cycle can be realized at the same time. Compared with the prior art, the valve is compact in structure, small in mounting space and convenient to maintain.
