Abstract

The invention provides a liquid refrigerant detection sampling device. The device comprises a sampling bottle with a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet of the sampling bottle are respectively connected to a first regulating valve and a second regulating valve. In liquid refrigerant sampling, the first regulating valve and the second regulating valve are opened simultaneously, the first regulating valve is connected to a refrigerant pot valve, the refrigerant pot valve is opened, a liquid refrigerant is injected into the sampling bottle, after air in the sampling bottle is completely discharged, the second regulating valve is opened, and when the liquid refrigerant satisfies sampling requirements, the refrigerant pot valve and the first regulating valve are closed so that a sampling process is finished. After the sampling bottle is taken off from the refrigerant pot, the sampling bottle can be connected to a fluorine injection pipe and a moisture test sample introduction needle by the first regulating valve or the second regulating valve for cooperation so that through the first regulating valve and the second regulating valve, refrigerant flow can be controlled so that a test is convenient and liquid refrigerant sampling difficulty is reduced. The invention also provides a liquid refrigerant detection sampling method used by the device.

Description

technical field [0001] The invention relates to the technical field of refrigerant sampling and detection, and more specifically relates to a sampling device and a sampling method for liquid refrigerant detection. Background technique [0002] The body of the existing refrigerant sampling bottle is relatively thin, and only gaseous refrigerant can be sampled. When it is necessary to test the liquid refrigerant, it needs to be connected with an adapter to cooperate with the fluorine injection tube and the test sample needle to realize the sampling of the liquid refrigerant. [0003] When the adapter is used to connect the sampling bottle to sample the liquid refrigerant, the outflow of the liquid refrigerant cannot be controlled. After the liquid refrigerant flows out, it is easy to cause pressure on the pressure-bearing capacity of the sampling bottle and affect the sampling safety of the sampling bottle. [0004] Therefore, how to reduce the difficulty of sampling the liqu...
