Problems solved by technology

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 air flow and the size control of the air flow at any time according to the patient's condition. The existing air valve cannot be used in the medical ventilator. The air valve that automatically realizes the on-off of the air flow and can control the flow of the air flow has become a problem to be solved

Abstract

The invention relates to a diaphragm type respiratory flow rhythm control air valve, which can be switched on or off in an electronic control manner and can adjust air flow. A two-position three-way electromagnetic valve is connected with a valve body to realize on and off of the electronic control air valve, by the aid of a steel ball and a linear reversely conical cavity in the air valve, the size of a ventilating gap is increased linearly, the distance between a top post and a valve spool is controlled via a spiral mechanism, and control adjustment of the air flow is realized. After the structure is adopted, the diaphragm type respiratory flow rhythm control air valve has the advantages that the diaphragm type respiratory flow rhythm control air valve is smart in structure, the valve spool is high in movement precision and low in noise, the air valve can be switched on or off in the electronic control manner, the air flow can be adjusted, and the diaphragm type respiratory flow rhythm control air valve is suitable to be applied into medical breathing machine equipment.

Description

technical field [0001] The invention relates to the technical field of an air valve device in a medical ventilator, in particular to a diaphragm-type breathing flow rhythm control air valve which can be switched on and off by electric control and can adjust the flow rate of the airflow. 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 an...
