Description
Technical field
The general safety valve that the utility model relates to lead acid accumulator and is applied to lead acid accumulator.
Background technology
Lead acid accumulator is provided with safety valve, and it has three effects:
1, safe handling: promptly when inner generation gas atmosphere reaches the safety valve pressure in the storage battery use, drive valve pressure is discharged, prevent to produce generations such as battery is out of shape, breaks.
2, sealing function: safety valve cuts out when accumulator internal pressure is lower than closing valve and pressing of safety valve, prevents the internal gas acid mist toward external leakage, also prevents from that air from entering simultaneously to cause harmful effect in the battery; And can prevent that the hydrogen of separating out from producing tempering when meeting naked light, thereby ignite inside battery gas.Has explosion-proof.
3, guarantee that storage battery has certain interior pressure, promote that oxygen is compound in the storage battery, reduce dehydration.
Present safety valve is explosion-proof and filter acid is limited in one's ability, influences the safe handling of lead acid accumulator.
Summary of the invention
The utility model technical problem at first to be solved provides a kind of general safety valve that can improve the lead acid accumulator of explosion-proof and the sour ability of filter.For this reason, the utility model is by the following technical solutions: it comprises valve seat, valve seat is provided with the exhaust passage, described exhaust passage is provided with the lip cap, along the discharge directions of exhaust passage, described general safety valve is provided with down burst disk in the upstream of lip cap, on the downstream is provided with burst disk, on exhaust cap and following exhaust cap, last burst disk is between exhaust cap and the following exhaust cap, and the described exhaust cap that goes up is provided with steam vent with following exhaust cap.Because adopt the technical solution of the utility model, safety valve provided by the utility model has increased dual explosion-proof, dual filter acid function on the basis of conventional security valve; The three-decker of last burst disk, last exhaust cap and following exhaust cap also has anti-acid mist function.
Another technical problem to be solved of the utility model provides a kind of energy and improves lead acid accumulator explosion-proof and the sour ability of filter.For this reason, the utility model by the following technical solutions: it comprises negative pole, positive pole, safety valve, and described safety valve is located between negative pole and the positive pole, and described safety valve adopts above-mentioned safety valve.Because adopt the technical solution of the utility model, lead acid accumulator provided by the utility model has dual explosion-proof, dual filter acid function; The three-decker of last burst disk, last exhaust cap and following exhaust cap also has anti-acid mist function, thereby has improved the safety in utilization of lead acid accumulator greatly.

Embodiment
With reference to accompanying drawing.General safety valve provided by the utility model comprises valve seat 5, valve seat is provided with exhaust passage 50, described exhaust passage is provided with lip cap 8, discharge directions along the exhaust passage, described general safety valve is provided with burst disk 6 down in the upstream of lip cap, on the downstream is provided with burst disk 3, on exhaust cap 2 and following exhaust cap 4, last burst disk is between exhaust cap and the following exhaust cap.Drawing reference numeral 7 is a rectangular seal, and it is that valve seat seals when cooperating with battery cover.
The described burst disk that goes up fits tightly with last exhaust cap and following exhaust cap, and last exhaust cap and following exhaust cap are supported on respectively on the step surface in the exhaust passage 50, and last burst disk is clamped between them by last exhaust cap and following exhaust cap.
The described exhaust cap that goes up is respectively equipped with steam vent 9 with following exhaust cap, and the steam vent of described upward exhaust cap and/or the steam vent 9 of following exhaust cap are the taper type hole.The lead acid accumulator gas inside can evenly be separated out, and make gas easily go out to be difficult for into (gas unidirectional), and can improve the explosion-proof performance of valve body.
General safety valve provided by the utility model also is provided with top cover 1 in the upper end of valve seat, it is connected the valve seat upper end, top cover 1 can play decoration function, but the more important thing is, it not only plays the fixing effect of going up burst disk, going up the three-decker of exhaust cap and following exhaust cap, and its reality also makes safety valve have the function of electricity storage preventing pond short circuit.As shown in Figure 4, lead acid accumulator provided by the utility model, its upper end is provided with positive pole 102 and negative pole 101, general safety valve 100 provided by the utility model is located between negative pole 101 and anodal 102, the top 12 of described top cover is higher than negative pole and positive pole, like this, in case when instrument 200 falls, can prevent negative pole and anodal by short circuit.
Described top cover 1 is pressed on the exhaust cap 2, and the bottom surface 10 of described top cover protrudes 11 in the middle of last exhaust cap direction, and arc transition is arranged, and the described steam vent of going up exhaust cap is in outside the contact site of exhaust cap and described top cover bottom surface protrusion 11.Prevent that the exhaust outlet 9 that will go up exhaust cap 2 when top cover 1 and valve seat assembling tension from blocking, and help gas to around diffusion, strengthen explosion-proof effect.
The surface of described valve seat also is provided with back stop slot 51.
The retaining wall 53 that the surface of described valve seat is provided with the lead-in chamfered 52 of back stop slot and is higher than the back stop slot notch prevents that the general safety valve from can unclamp in bounce-back, causes battery failure after screwing.
