The normally understood meaning of art personnel institute.
As shown in Figure 1, a kind of bionical natural gas filling tank provided by the utility model, including the shell 7 with inner cavity, shell
Sliding is provided with a piston plate 6 in body 7, and piston plate 6 is arranged along the vertical direction of shell 7, a left side of the piston group 6 in shell 7
Right direction moves in parallel, and the displacement sensor 5 of the position of reflection piston plate 6 is equipped on piston plate 6, natural in tank body to prompt
Gas surplus, using intuitive and convenient, design is more humanized, usually from the point of view of scene actually uses situation, 7 preferred design of shell
For cylindrical tube shape structure parallel in left-right direction, piston plate 6 is preferably designed for circle.
The inner cavity or so of shell 7 is divided into slack tank part 8 and filling part 9 by piston plate 6, and the outside of shell 7 is set respectively
There are the first valve group 1, the second valve group 2, third valve group 3 and the 4th valve group 4, the first, second valve group 1,2 connects with slack tank part 8 respectively
