| titleOfInvention | Gas sampling system |
| abstract | The utility model provides a gas sampling system relates to oxygen detection field in the brazing furnace, including sampling main road, multiunit parallel connection's sampling branch road and nitrogen gas main road, the sampling branch road is connected with sampling main road through first pipeline, and sampling main road, first pipeline and nitrogen gas main road are connected through the tee bend, and the series connection has oxygen analyzer and vacuum pump on the sampling main road, lets in nitrogen gas in the nitrogen gas main road, is equipped with relief pressure valve and normally open solenoid valve on the nitrogen gas main road, is equipped with first solenoid valve on every group sampling branch road, and the continuous nitrogen gas that lets in to the stove when not sampling prevents that the pipeline from blockking up; compared with the existing system, the high-pressure purging process is removed, the temperature of the atmosphere in the furnace is prevented from being suddenly reduced, and the stability of the furnace temperature and even the brazing process of the product are prevented from being influenced; the system simplifies the sampling pipeline and greatly reduces leakage points. |
