The invention discloses an automatic detector for safety valve opening and closing pressure. The cross section of a box body (1) is in an L shape to form an operation table top (15); the outer wall of the box body (1) is provided with an oil-water separator (18) and a pressure gage (17); a programmable programming controller (12) is arranged in the box body (1); the box body (1) above the operation table top (15) is provided with an air cylinder (4) and a digital display pressure gage (2); the air cylinder is connected with an air cock joint (5); the box body (1) below the operation table top (15) is provided with a start button (11), a stop button (7), a pressure maintaining timer (8), an inflated time (9) and a timer (10) to be aerated; the oil-water separator (18) is connected with the air cylinder (4) and the pressure gage (17); and the programmable programming controller (12) is connected with the digital display pressure gage (2), the oil-water separator (18), the air cylinder (4), the start button (11), the stop button (7), the pressure maintaining timer (8), the inflated time (9) and the timer (10) to be aerated. The automatic detector can ensure the consistency and the continuity of the safety valve opening and closing pressure, thereby improving the performance of a battery.
Description
technical field [0001] The invention relates to an automatic tester for a safety valve of a battery, in particular to an automatic tester for the opening and closing pressure of a safety valve of a maintenance-free motorcycle battery. technical background [0002] Lead-acid battery is a kind of "resource recycling" energy product with high safety, stable electrical performance, low manufacturing cost, wide application fields, and low-cost renewable utilization. In the past ten years, with the development of the world's energy economy and the improvement of people's living standards, lead-acid batteries, as a "green" industry that does not consume earth resources, will face a broad space for development. [0003] In the production process of lead-acid batteries, especially in the production process of valve-regulated sealed lead-acid batteries, the safety valve, as an important part, has a very important impact on the performance of the battery. In the case of normal use...
