Abstract

The invention relates to a respiratory flow rhythm control gas valve which can be opened or closed by electric control and can regulate the magnitude of gas flow. In the invention, a two-position three-way electromagnetic valve is connected with a valve body to enable the gas valve to be opened or closed by electric control, and the change of the size of a ventilation gap is linearly increase through a steel ball in the gas valve and a linear inverted cone-shaped cavity, thus the travel distance between a support pillar and a valve core can be controlled through a screw mechanism so as to realize the purposes of controlling and regulating the magnitude of gas flow. By adopting the structure, the respiratory flow rhythm control gas valve has the characteristic of artful structure, can be opened or closed by electric control, can regulate the magnitude of gas flow, and is suitable for being applied in medical respirators.

Description

technical field [0001] The invention relates to the technical field of an air valve device in a medical ventilator, in particular to a breathing flow rhythm control air valve that can be switched on and off by electric control and can adjust the airflow flow. Background technique [0002] At present, the existing air valve has a relatively simple structure, which realizes the on-off of the air flow by moving the valve core up and down. However, the existing air valve usually needs to manually adjust the valve core to realize the on-off of the air flow, and the flow rate of the air flow cannot be controlled. In the medical ventilator, it is necessary to realize the on-off of the electronically controlled airflow and the size control of the airflow at any time according to the patient's condition. The existing air valve cannot be used in the medical ventilator. In view of this, how to design a Controlling the on-off of the air-flow automatically and the air valve capable of c...
