Example Embodiment
[0040] Example one
[0041] Such as figure 2 As shown, the valve body includes a seal and opening of the entire monitoring conduit 1 by the first valve body 3 along the empty lane side, and is closed by the first valve body 3; when the temperature collected and the gas collection is collected, Open the corresponding first valve body 3, in conjunction with the monitoring pipe 1; after standing for 10-20 minutes, the air and temperature measurement operation is performed; after the air intake, the temperature is measured, the acquisition unit 2 will be monitored. Remove, then quickly close the corresponding first valve body 3.
Example Embodiment
[0042] Example 2
[0043] Such as figure 2 As shown, the valve body includes a second valve body 4 provided and a second valve body 4 provided on one side of the empty area, and the second valve body 4 is provided in a control assembly along the railway. Control is opened, closed; when the temperature acquisition is collected with the gas collection of the vacuum area, the corresponding first valve body 3 opens, and the monitoring collecting unit 2 is extended to monitor the tube 1; at this time, the second valve body is controlled by the control assembly. 4 Open; after standing for 10-20 minutes, perform air intake and temperature measurement operation; after the air intake, after the temperature is measured, the second valve body 4 is turned off by controlling the component; after the residual gas of the tube 1 is tested, The monitoring acquisition unit 2 is taken out, and then the corresponding first valve body 3 is turned off; thus avoiding the gas of the gas in the empty area...
Example Embodiment
[0048] Example three
[0049] Such as Figure 3-4 As shown, the monitoring acquisition unit 2 includes a rubber plug 15 that is fitted to the monitoring conduit 1, and the glue plug 15 can be blocked in the monitoring conduit 1; the temperature measurement wire 19 is in the rubber plug 15; bundle The tube 16 is connected to the gas automatic negative pressure sampler 17 (Model: CFZ-30) along the end of the empty lane, and the other end of the beam tube 16 is blended with the monitoring pipe 1, extending in the vacuum area. On the side; the temperature warping wire 19 is connected to the explosion-proof multimeter 20 (model Metraline EXM 25A) close to the empty lane, and the temperature control probe 18 is connected, the explosion-proof multi-purpose table 20 is connected by temperature measurement wire 19 The probe 18 forms a set of monitoring devices, and after the glue plug 15 is mounted with the monitoring pipe 1, the temperature measurement probe 18 extends on one side of the v...
