Problems solved by technology

[0003] Since the structure composed of the valve plate assembly and the elastic member is a typical spring vibrator system, when the air flow is released, the valve plate assembly opens and closes quickly, and when the opening and closing frequency of the valve plate assembly is close to the resonance frequency of the spring vibrator, vibration will occur Abnormal sound, bringing noise impact to users

Abstract

The invention discloses an anaesthesia machine and an APL valve thereof. The anaesthesia machine comprises a breathing circuit, a fresh gas branch, a manual driving gas branch, a discharge branch and the APL valve, and the APL valve is installed on the manual driving gas branch to limit the gas pressure in the manual driving gas branch. The APL valve comprises a valve seat assembly, a pressure adjusting assembly, a valve plate assembly and an elastic piece; the valve seat assembly is provided with an gas inlet and an gas outlet, the gas inlet is communicated with the manual driving gas branch, the gas outlet is communicated with the discharging branch, and the pressure adjusting assembly is movably installed on the valve seat assembly. The valve plate assembly is in sliding connection with the pressure adjusting assembly, an gas cavity is defined by the valve plate assembly and the pressure adjusting assembly, the valve plate assembly is used for controlling connection and disconnection between the gas inlet and the gas outlet, the elastic piece is arranged in the gas cavity, the first end of the elastic piece abuts against the pressure adjusting assembly, the second end of the elastic piece abuts against the valve plate assembly, and the APL valve is further provided with a damping hole communicating the gas cavity with the outside. The damping hole is used for discharging and sucking gas in the gas cavity so as to restrain resonance of the valve plate assembly.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an anesthesia machine and an APL valve thereof. Background technique [0002] The APL valve is a commonly used valve in the field of anesthesia machines, mainly used for the gas pressure control of the manual drive gas branch of the anesthesia machine. The principle is that the APL valve is provided with an air inlet and an air outlet, and the valve plate assembly seals the air inlet through the elastic force of the elastic member. When the pressure in the air inlet is greater than the elastic force of the elastic member, the gas pushes open the valve plate assembly and It is released from the gas outlet, so as to control the gas pressure in the manual driving gas branch. [0003] Since the structure composed of the valve plate assembly and the elastic member is a typical spring vibrator system, when the air flow is released, the valve plate assembly opens and closes quickly, an...
