1, installation steps are reasonable in design, simple to operate, construction safety, reliable;
2, the temporary measure that needs is few, reduces the temporary measure expense;
3, guarantee not affect production installation caloric value instrument and get source block;
But finish online installation, reducing construction cost in 4 short time.
Description of drawings
Fig. 1 is that the caloric value instrument of the embodiment of the invention is got source block and base, valve, the connection diagram of bushing and short tube;
Fig. 2 is the base welding schematic diagram of the embodiment of the invention;
Fig. 3 be the embodiment of the invention at the pipeline schematic diagram of holing.
Among the figure: 1 caloric value instrument is got source block, 2 pipelines, 3 valves, 4 short tubes, 5 bushings, 6 welds, 7 bases, 8 borings.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is illustrated further.
Embodiment 1
Now see also Fig. 1, Fig. 1 is that the caloric value instrument of the embodiment of the invention is got source block and base, valve, the connection diagram of bushing and short tube.Caloric value instrument of the present invention is got the online installation method of source block, it is characterized in that may further comprise the steps:
