| description | The utility model discloses a two-way check valve and a device for providing nitrogen during shutdown, which relates to the technical field of air separation and comprises a pipeline shell, a left connecting nut, a right connecting nut and a regulating valve nut. The adjusting unit comprises an adjusting valve, a water stop plate, a rotating assembly and a non-return plate; and the nitrogen supply unit comprises a liquid nitrogen vehicle filling pump, an accident nitrogen pump, a valve, an air bath type vaporizer and a water bath type vaporizer. The nitrogen conveying device has the advantages that the directions of the through-flow plate and the spoiler are adjusted through the adjusting valve, conveying and spoiling of nitrogen can be achieved, the check plate can prevent backflow of the nitrogen, and the check plate is matched with the adjusting valve to adjust the direction of the water stop plate, so that two-way flowing of the nitrogen can be achieved, and impact of backflow is eradicated; by introducin |
