Description

Technical Field

[0001] The utility model relates to the technical field of natural gas gathering and transportation, and particularly relates to a quick-change temperature and pressure measurement data stub. Background Art

[0002] For the acquisition of process data such as temperature and pressure on the throttle pipeline of the existing natural gas heating furnace, it is usually adopted to open holes on the steel pipe stub and weld corresponding pipe sockets with connecting threads to install the measurement module, so as to realize the temperature and pressure measurement of the pipeline. This installation method has certain drawbacks. When the pipe socket is directly welded to the pipeline stub, problems such as slag inclusion and porosity are likely to occur in the weld. At the same time, when the steel pipe stub is put into use and there is sand in the natural gas, the part of the temperature measurement module pipe socket extending into the steel pipe stub is extremely easy to be washed out. Since the temperature measurement module does not bear pressure, after the temperature measurement module pipe socket is washed out, it needs to be replaced immediately. However, since the pipe socket is directly welded to the steel pipe stub, to replace the pipe socket, the heating furnace needs to be shut down, and the pipe socket is cut off by hot work and then a new pipe socket is welded, resulting in a long construction period and certain potential safety hazards.

The temperature of the medium is conducted to the middle pipe seat, and the middle pipe seat then transfers heat to the thermometer 4 or the temperature transmitter 5 to achieve the purpose of temperature measurement, and the collected temperature data is transmitted to the central control system; when the gas passes under the pressure measurement module, since the pressure transmitter 6 and the pressure gauge 7 are respectively connected to the steel pipe short circuit 1 through the first sampling stop valve 8-1 and the second sampling stop valve 8-2, when the sampling stop valve is opened, the air pressure will directly act on the pressure transmitter 6 and the pressure gauge 7.
