Sulfur hexafluoride gas sampling device and sampling test method

The invention discloses a sulfur hexafluoride gas sampling device and a sampling test method.The device is provided with a multi-way valve and a transfer valve, the multi-way valve and the transfer valve are matched with a recovery bottle and a sampling bottle, residual gas in the sampling bottle and a pipeline connected with equipment is collected into the recovery bottle, then gas in the recovery bottle is discharged in order, and when the equipment is connected, the sampling bottle is connected with the recovery bottle through the transfer valve. The recycling bottle can purify the pipeline connected with the equipment and then sample through the sampling bottle, so that disordered emission of the sulfur hexafluoride gas is controlled, the device is more environment-friendly, the recycling bottle purifies the pipeline before sampling, the sampling gas is more consistent with the gas in the equipment, and the detection result is more reliable. 本发明公开了一种六氟化硫气体取样装置和取样测试方法，本装置设有多路阀和转移阀，配合回收瓶和取样瓶，将取样瓶、连接设备的管路中的残
