Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
In Fig. 1,2, the utility model is used for lead-acid accumulator exhaust cap, and labyrinth retaining wall includes the labyrinth that position covers greatly
Barricade one, positioned at the small labyrinth retaining wall two covered.Labyrinth retaining wall one is by outer arcuate barricade 1, arc barricade 2, oblique line barricade one
3rd, vertical barricade 5 is formed.The circular barricade that outer arcuate barricade 1 is formed is designed in the middle part of battery big cover, and steam vent 11 is kept off in circle
Within the walls.When battery tilts forward and back, sulfuric acid liquid level is not easy to be discharged at labyrinth below exhaust outlet, and gas is easily drained to labyrinth
Place.Circular barricade has 2 openings up and down, and 2 arc barricades 2 are distributed at the upper and lower opening of circular barricade, circular barricade and
Gap between arc barricade 2 is gas outlet channels 6, the sectional area transition from small to large of passing away 6, can make sulfuric acid not
Easily be discharged to outside labyrinth, sulfuric acid easily from labyrinth exteenal reflux to battery case in.4 oblique line barricades 1 are distributed in circular barricade
Outside, oblique line barricade tilt 45 ° or so.Sulfuric acid backflow at one 3 pairs of labyrinths of oblique line barricade play the guiding role, the sulphur between big tegillum
Under acid acts on slope, flow direction middle part, it can be flowed into along oblique line barricade 1 in exhaust outlet to battery case.Air filter piece is loaded on air filtration
Piece installation site 4, there are 2 vertical barricades 5 in air filter piece both sides.Vertical barricade 5 can prevent sulfuric acid from entering air filter piece installation site
