Braided bag is arranged gas detection and is surveyed device

The utility model relates to a braided bag is arranged gas detection and is surveyed device, including box and fan, air -out pipeline, solenoid valve, flow sensor, the pressure sensor of setting in the box, the one end and the fan of air -out pipeline are connected, the solenoid valve, flow sensor, pressure sensor all connects on the air -out pipeline, the other end of air -out pipeline extends tothe box and forms the air outlet outward, the air outlet top is provided with the cylinder, the ejector pin of cylinder is just to leaning on the air -out pipeline on one side of the air outlet, flowsensor's signal output part and pressure sensor's signal output part are connected to data processing module's input respectively, data processing module's output is connected to digital display screen's input. This practicality is punched the technique of braided bag and is compared with the current tectorial membrane that detects, and it is more accurate to measure the exhaust precision, and the operation is more conven
