Under, it is also possible to obtain other drawings based on these drawings.
Attached drawing 1 is a kind of structural schematic diagram of the emptying device of flammable explosive gas.
In figure: 1. fire arresters, 2. check-valves, 3. second blow-down pipes, 4. scavenging conduits, 5. blow down valves, 6. second air accumulators, 7.
First blow-down pipe, 8. blow valves, 9. first air accumulators.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of emptying device of flammable explosive gas as one preferred embodiment of the utility model, including
First air accumulator 9, the second air accumulator 6, the first blow-down pipe 7, the second blow-down pipe 3, threeway and scavenging conduit 4, first blow-down pipe 7
