Embodiment Construction
[0030] A gas valve device with flow monitoring, such as Figure 1 to Figure 4 As shown, it is mainly suitable for medical oxygen pipelines, including a shut-off valve 2 arranged on the airflow pipeline 1 and controlling the on-off of medical oxygen in the airflow pipeline 1. The shut-off valve 2 is installed in a straight line connection with the airflow pipeline 1. On the shut-off pipeline 3 of the shut-off valve 2, the valve body 20 of the shut-off valve 2 is integrally formed and connected with the shut-off pipeline 3; the shut-off pipeline 3 corresponding to the shut-off valve 2 extends outwards with a boss 30 integrally formed, and a step is provided inside the boss 30 Shaped through-hole groove 300, the flow sensor chip 4 and PCB board 5 for measuring the air flow are packaged in the through-hole groove 300, and the flow sensor chip 4 is located at the opening of the through-hole groove 300 towards the cut-off pipe 3, using At this time, the flow sensor chip 4 adopts flo...

The invention provides a gas valve device with a flow monitoring function. The gas valve device comprises a stop valve arranged on a gas flow pipeline and controlling flowing and stopping of medical gas in the gas flow pipeline. The stop valve is installed on a stop pipeline linearly connected with the gas flow pipeline. A valve body of the stop valve is connected with the stop pipeline in an integrally formed mode. The part, corresponding to the stop valve, of the stop pipeline is provided with a boss in an externally integrally formed and extending mode. A step-shaped through hole groove is formed in the boss. A flow sensing chip used for measuring gas flow and a PCB are packed in the through hole groove. A pressing plate and fixing screws which conduct pressing, sealing and fixing in the through hole groove are arranged at the top end, corresponding to the open end of the through hole groove, of the boss. The fixing screws press and fix the PCB and the flow sensing chip which are superposed sequentially up and down in the through hole groove of the boss through the pressing plate. The side wall of the boss is further provided with a chip interface which communicates with a power line and a signal line on the PCB in the through hole groove so that the flow sensing chip can achieve signal output conveniently.
Description
[0001] 【Technical field】 [0002] The invention relates to medical terminal detection technology, in particular to a gas valve device with flow monitoring. [0003] 【Background technique】 [0004] At present, the medical gases commonly used in hospitals include oxygen, negative pressure, compressed air, laughing gas (anesthetic gas), carbon dioxide, etc. The gas pressure in the medical gas pipeline is usually relatively high. Taking the medical oxygen system as an example, the national standard requires terminal pressure It must not be lower than 0.4MPa. Therefore, it is particularly important to monitor the gas flow in the medical gas pipeline ("gas pipeline" for short, the same below). Before there was no central gas supply system, the hospital had to move oxygen cylinders, negative pressure suction devices, air compressors and other bottled gases into wards or operating rooms to use these gases, which greatly increased the labor intensity of medical staff. It has brought ma...
