Beschreibung
Zusammenfassung:	The utility model discloses an exhalation valve with high positive end expiratory pressure, steady flow and no abnormal sound, which comprises a sampling tube front end, a sampling tube rear end, a sampling seat, an exhalation valve shell and a valve cover, the sampling tube front end comprises a sampling tube front end, the sampling tube rear end comprises a sampling tube rear end ventilation cavity channel, the sampling tube rear end ventilation cavity channel comprises a sampling tube rear end ventilation cavity channel air inlet end and a sampling tube rear end ventilation cavity channel air outlet end, and the top of the sampling tube front end and the top of the sampling tube rear end are connected with a sampling seat. The two-way conical gas path is more stable in gas flow, the possibility of abnormal exhalation sound is avoided, the upper limit of PEEP performance is effectively improved, the front end and the rear end of the sampling pipe are horizontally arranged in the exhalation valve shell, so t
