Problems solved by technology

[0002] The battery is the main power source of the traction locomotive. During the use of the battery, some water in the electrolyte will be decomposed to form gas. The diffusion of the gas will take away the sulfuric acid in the electrolyte, resulting in a decrease in the sulfuric acid content of the battery electrolyte, thus Reduce the capacity of the battery and affect the use of the battery

Abstract

The invention discloses an anti-acid mist type battery filling cap. The battery filling cap comprises a cap body, wherein the cap body is sealed with a battery cap through threads; a labyrinth loop is arranged on the top surface of the cap body; a cap is arranged at the upper part of the cap body, and covers the labyrinth loop; an anti-acid mist piece is arranged in the cap; a reflowing hole is formed in the centre of the labyrinth loop; exhaust holes are formed in the cap. During the use of the storage battery, acid mist brought from the decomposed electrolyte solution passes through the labyrinth loop to form liquid drops to flow back into the storage battery, a small quantity of acid mist which does not form liquid drops is filtered through the anti-acid mist piece, and gas generated by water decomposition is exhausted through the exhaust holes in the cap. Therefore, the content of a combustible gas in the storage battery is reduced, the acid volume in the electrolyte solution of the storage battery can be efficiently guaranteed, and the service life of the storage battery is prolonged.

Description

technical field [0001] The invention relates to a lead-acid battery, in particular to an acid mist-proof liquid injection cover for the battery. Background technique [0002] The battery is the main power source of the traction locomotive. During the use of the battery, some water in the electrolyte will be decomposed to form gas. The diffusion of the gas will take away the sulfuric acid in the electrolyte, resulting in a decrease in the sulfuric acid content of the battery electrolyte, thereby Reduce the capacity of the battery and affect the use of the battery. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an acid mist-proof battery liquid injection cover, which can return the sulfuric acid taken away by the decomposed water into the battery, ensure the acid content in the battery electrolyte, and improve battery life. [0004] The technical solution adopted in the present invention is: an acid mist-proof b...
