Embodiment
Below by best embodiment, the utility model is described in detail
.
As shown in Figure 1, empty minute nitrogen ensuring equipment without interruption, it comprises steam line 5, bailout gas 1, switched system 4 and voltage-regulating system 2; Described bailout gas 1 comprises the vaporizer 22 of the liquid nitrogen storage tank 21 connected successively, connected electromagnetic valve 201 between liquid nitrogen storage tank 21 and vaporizer 22; Voltage-regulating system 2 comprises the second valve 102, and vaporizer 22 connects the second valve 102 by the first valve 101; Described switched system 4 comprises pressure transmitter 301, pressure transmitter 301 connected electromagnetic valves 201 and the 5th stop valve 202, and pressure transmitter 301 also connects the steam line 5 that steam line 5, the second valve 102 outlets connect the 5th stop valve 202 rear ends.
Also comprise pressure relief system 3, pressure relief system 3 comprises safety valve 108 and atmospheric valve 107, and safety valve 108 and atmospheric valve 107 are installed on the connecting pipeline between steam line 5 and the second valve 102.
The first pressure gauge 11 is set on the outlet conduit of vaporizer 22.
On the second valve 102 outlet conduits of voltage-regulating system 2, the second pressure gauge 12 is set.
Described voltage-regulating system 2 also comprises two pipelines parallel with one another, wherein on a pipeline, sets gradually the first stop valve 105, modulating valve 203 and the second stop valve 106; Set gradually the 3rd stop valve 103, the second modulating valve 204 and the 4th stop valve 104 on another pipeline, above-mentioned two pipelines are parallel to respectively the second valve 102 two ends.
