Acid accumulation bottle

Abstract

The invention relates to an acid accumulation bottle in the field of storage batteries. A main body of the acid accumulation bottle is a bottle body; the top of the bottle body comprises a first spring, a first valve body, a second spring, a second valve body and a sealing valve head B, wherein a sealing valve head A is arranged at the end part of the first valve body; the first valve body is arranged at the top of the bottle body in a telescopically matched manner, a valve plate is integrated in the bottle body and is near to the top, the first spring sleeves the first valve body, and the sealing valve head A is sealed to a valve port of the valve plate under the action of the first spring; the second valve body is connected with the first spring in a sleeving manner and is slidably arranged in the first valve body in a telescopically matched manner, one end of the second valve body stretches out of the top of the first valve body to serve as a button part under the action of the second spring, the other end of the second valve body stretches out of the sealing valve head A of the first valve body to be connected with the sealing valve head B, and the sealing valve head B is sealed to an end face of the sealing valve head A under the action of the second spring; and a first air hole is formed in the side wall of the first valve body, and a second air hole communicating with the outside of the bottle body is formed in the side wall of a chamber formed by the top and the valve plate in the bottle body. According to the acid accumulation bottle provided by the invention, automatic and manual pressure relief and exhaust can be realized, so that the working stability is improved.

Description

technical field [0001] The invention relates to an auxiliary part of a storage battery, which is an acid storage bottle. Background technique [0002] The acid bottle is a bottle that can collect or accumulate acid, and the material itself has the characteristics of acid resistance and corrosion resistance. For example, the authorized announcement number CN202094240 published in the Chinese patent literature, the authorized announcement date was December 28, 2011, and the name of the utility model is "reflux exhaust device for preventing battery from turning into electrolyte overflow". Composed of valves, the upper and lower ports of the return pot are respectively provided with connecting threads, the exhaust plug is located at the upper end of the return pot and screwed with the thread of the return pot, the pressure reducing valve is located in the exhaust plug, the lower end of the return pot is connected to the liquid injection hole of the battery cover Threaded.
