Specific embodiment
In order to facilitate the understanding of those skilled in the art, the utility model will be further described below with reference to the accompanying drawings.
A kind of explosion-proof sealing ring used for dry cell as shown in Figs 1-4, including sealing ring main body 1, in the sealing ring main body 1
Hollow pillar stand 2 is equipped at the heart, the one end of the hollow pillar stand 2 far from the sealing ring main body 1 is equipped with pressure relief device, the sealing
Circle main body 1 is matched with pressure relief device, and the sealing ring main body 1 is equipped with reducible elastic element with pressure relief device, described close
It is set as fluid reservoir 4 between seal main body 1 and pressure relief device, the sealing ring main body 1 in the fluid reservoir 4 is equipped with boss 5,
The boss 5 be equipped with the stomata 6 that is connected of the external world, the boss 5, hollow pillar stand 2 and 1 integrally casting of sealing ring main body into
Type.
The pressure relief device includes pressure relief plate 7 and fixed plate 9, and the pressure relief plate 7 is equipped with relief hole 8, the fixed plate 9
