Safety valve and storage battery using same

The utility model belongs to the field of storage batteries, particularly relates to a safety valve and a storage battery using the safety valve, and provides the following scheme aiming at the problems that when an existing storage battery is used, the battery gradually generates gas, the gas cannot be discharged in an aluminum shell of the battery, so that the battery is swelled, accidents are easy to occur, and the safety coefficient is relatively low. The top of the valve seat is fixedly connected with a filter disc, the top of the valve seat is fixedly connected with a decorative cover, the decorative cover is located above the filter disc, the top of the valve seat is fixedly sleeved with a rubber cap, and the rubber cap is located below the filter disc. When the battery is inflated, gas can be exhausted through the filter disc, so that the effects of exhausting the gas in the battery and improving the safety of the device can be achieved, and the effect that the battery is not inflated can be achieved
