Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can be mutually combined.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, the embodiment of the present invention is a kind of gas analyzing apparatus, the device includes：Main pipeline 10, detection means 30
And cleaning pipeline 50.Wherein, main pipeline 10 is used to be passed through detection gas, detection port and the main pipeline 10 of detection means 30
Connection, detection means 30 is used to detect the gas to be detected in main pipeline 10.The pipeline section for cleaning pipeline 50 and main pipeline 10 connects
Logical, cleaning pipeline 50 is used to be passed through clean gas.After gas detection has been carried out, clean gas is passed through in cleaning pipeline 50,
To take away the detection gas remained in device by clean gas.
The embodiment provided using the present invention, by setting cleaning pipeline 50 on main pipeline 10 so that after gas detection is terminated,
By clean gas from cleaning pipeline 50 be passed through main pipeline, and then can be taken away by clean gas remain in it is residual in main pipeline 10
Residual air body.It so can quickly and easily remove residual gas, it is to avoid next detection band is disturbed.
Wherein, in the case where main pipeline 10 is not passed through detection gas, clean gas is only passed through, can be taken away by clean gas
Detection gas in device.Alternatively, in order to further improve elimination effect, cleaning pipeline 50 is cleaned into pipeline 50 and is arranged on
Between detection means 30 and arrival end.
Alternatively, in order to avoid to detecting that the detection data of gas produce interference, selection nitrogen is used as clean gas.
For the ease of control clean gas flow, specifically, valve 51 is provided with cleaning pipeline 50.
In specific operation process, being passed through for detection gas is first closed, nitrogen valve 51 is then opened, and control by valve 51
Nitrogen, is gradually passed into device by the flow of nitrogen, and is kept for a period of time, in the process, and detection means 30 continues work
Make, when detection means can't detect detection gas, close valve 51.
Specifically, the gas analyzing apparatus also includes lateral 20, the first end of lateral 20 and the pipeline section of main pipeline 10
Connection, the detection port of detection means 30 is connected with lateral 20.By lateral 20 company is provided to detection means 30
Port is connect, so detection means 30 can be easy to detect.
In embodiments of the present invention, the device also includes guider 40, and guider 40 includes being arranged in main pipeline 10
First guide section and the second guide section extended in lateral 20, the first guide section are connected with the second guide section with by main pipeline
Detection gas in 10 is imported in lateral 20, can so increase the flow that detection gas is passed through in lateral 20, so as to
Detected in 30 pairs of detection gases of detection means.Alternatively, the detection means 30 is residual gas analyzer.
Apply the technical scheme of the present invention, by increasing guider 40, Neng Gouzeng between main pipeline 10 and lateral 20
Plus detection gas enters the flow of lateral 20, and then the data that the detection means 30 in lateral 20 is detected
It is more accurate.
Specifically, the main pipeline 10 has arrival end and a port of export, and the opening of the first guide section is towards the arrival end side of main pipeline 10
To setting, in order to detect that gas enters in guider 40, and lateral 20 is sent into.
Alternatively, in order that the gas imported by guider 40 is easily detected by detection means 30, it is directed to the one of device 40
End is set close to the detection port of detection means 30.
