A safety valve for a lean liquid battery, comprising a valve body and a valve cover; a stepped inner hole is provided on the upper, middle, lower, and stepped valve body; There is an opening at the upper end of the cylinder; a sealing plastic cap is provided at the upper end of the inner cylinder; an air filter is arranged on the upper part of the sealing plastic cap; the air filter is clamped at the step in the middle of the inner hole; The lower end is provided with a gas-collecting port; the valve cover is provided with external threads, and the inner hole and the valve cover are correspondingly provided with internal threads that cooperate with the external threads of the valve cover and exhaust ports that cooperate with the external threads of the valve cover. The upper port of the exhaust channel at the lower part of the valve body of the present invention is provided with two symmetrical openings, and the lower end of the valve cover is provided with a cross-shaped gas collecting port, both of which play the role of unobstructed exhaust. When the pressure inside the battery reaches a certain level, it can flow through the gas passage on the valve body to the exhaust passage of the battery cover. The invention achieves centralized exhaust and can exhaust to both sides of the accumulator at the same time, and is easy to install.
Description
technical field [0001] The invention belongs to the technical field of accumulators, and relates to an AGM accumulator component for a weak hybrid vehicle, in particular to an AGM accumulator safety valve that can be opened and closed according to the internal air pressure of the accumulator. Background technique [0002] AGM battery is a kind of lean liquid battery. Compared with ordinary liquid rich battery, it has deeper discharge, more start and stop times, and better fuel saving effect. It can meet the needs of start stop system and general weak hybrid vehicles. Like ordinary flooded batteries, AGM batteries will produce hydrogen during the working process, and at the same time, to ensure the sealing of the batteries, reduce the loss of water in the batteries. During the battery design process, it is necessary to consider the gas discharge and sealing inside the battery at the same time. The existing safety valve can only realize the function of exhausting the upper en...
