The utility model discloses an air-tightness detecting device for a valve-regulated sealed lead-acid battery; the air-tightness detecting device is simple to manufacture, has low investment cost and convenience in operation and comprises a pressure gauge; the pressure gauge is connected with a three-way joint through a hose; the interface at the other end of the three-way joint is connected with an air bag through the hose; the interface at one end of the three-way joint connected with the air bag is opposite to the interface at one end connected with the pressure gauge; the three-way joint is further connected with a sealing nozzle, and the sealing nozzle is matched with a valve port of the lead-acid battery. The air-tightness detecting device for a valve-regulated lead-acid battery disclosed by the utility model has simpleness in manufacturing, low investment cost, relatively simple operation and is suitable for sampling inspection of battery air-tightness; and the inflowing of the batteries with sealing failure to the next procedure can be prevented.

Description

A kind of valve-control sealed lead acid battery air-tightness detection device
Technical field
The utility model relates to the bubble-tight detection of accumulator, particularly a kind of valve-control sealed lead acid battery air-tightness detection device.
Background technology
Air-tightness is the important indicator that detects valve-control sealed lead acid battery, if air-tightness is bad, will makes the accumulator leakage and can't use; It is requisite important step in the accumulator production process that the air-tightness of accumulator detects; The accumulator air-tightness detection device mainly is made up of valve, O-ring seal at present, but for valve-control sealed lead acid battery; Because this type of battery filler is less; Valve can not insert, and can't detect its air-tightness, directly influences the product quality of lead-acid accumulator.
In the production run of valve-regulated lead-acid battery; For a long time for the battery that uses epoxy resin to seal; The capital exists because the mobile bad or employee of glue splashes into the glue quantity deficiency when operation, causes battery cap poor sealing and brings hidden danger, like battery cap poor sealing (being referred to as to leak gas); Battery in use electrolytic solution flows out from the cap poor sealing, and the corrosivity of electrolytic solution can let uses the equipment of this battery to suffer damage.Like poor sealing between battery cell and the monomer (being referred to as to collaborate), then battery is in depositing process, and the self discharge meeting strengthens, and influences the performance of battery.Though in this industry various airtight detecting apparatus are arranged, when the input cost of equipment was changed battery size than higher and production run, commissioning device was complicated, influences production efficiency.
Summary of the invention
The purpose of the utility model is the shortcoming that overcomes prior art, and a kind of valve-control sealed lead acid battery air-tightness detection device is provided, and this device is made simple, and input cost is low, operates also fairly simple.
For reaching above-mentioned purpose; A kind of valve-control sealed lead acid battery air-tightness detection device that the utility model provides; Technical scheme below adopting: include tensimeter, it is characterized in that: said tensimeter is connected with three-way connection through flexible pipe, and the other end interface of said three-way connection is connected with air bag through flexible pipe; Said three-way connection is connected with an end interface of air bag and is connected with a manometric end interface position relative, and said three-way connection also is connected with sealed mouth.
Further, the valve port of said sealed mouth and lead-acid accumulator is complementary.
Further, said sealed mouth can be processed by rubber or plastic material.
The beneficial effect of the utility model is: this device is made simple, and input cost is low, operate also fairly simplely, even the new employee also can skillfully operate soon, this device is suitable surveys sample battery air tightness to battery.The battery that can prevent poor sealing flow into next operation, uses this device conveniently to detect battery air tightness, and this device is made simple, and material is obtained easily; This novel airtight pick-up unit is applicable to that the impermeability of pet-valve control sealed lead acid battery detects; Prevent that the bad battery of sealing property from flowing into next operation and the quality that influences battery; Detect through tensimeter, its gas leak phenomenon is easy to detect through tensimeter, and is more simple and clear; Gas replenishment process safety can not cause damage to accumulator.
Description of drawings
Shown in Figure 1 is the utility model example structure synoptic diagram.
Parts label title is following among the figure:
Tensimeter 1, three-way connection 2, air bag 3, sealed mouth 4, flexible pipe 5.
Embodiment
For further understanding characteristic, technological means and the specific purposes that reached, the function of the utility model; Resolve the advantage and spirit of the utility model, by the detailed description of the utility model further being understood below in conjunction with accompanying drawing and embodiment.
Shown in Figure of description; A kind of valve-control sealed lead acid battery air-tightness detection device that the utility model provided; Include tensimeter 1, said tensimeter 1 is connected with three-way connection 2 through flexible pipe 5, and the other end interface of said three-way connection 2 is connected with air bag 3 through flexible pipe 5; The end interface that said three-way connection 2 is connected with air bag 3 is relative with an end interface position that is connected with tensimeter 1, and said three-way connection 2 also is connected with sealed mouth 4.
Said sealed mouth 4 can be processed by rubber or plastic material, and said sealed mouth 4 is complementary with the valve port of lead-acid accumulator, so that sealed mouth 4 inserts in the valve port of accumulator.
Can adopt following detection method according to said apparatus: 1. be ready to said airtight pick-up unit and accumulator to be detected; 2. coincide the valve port of said sealed mouth 4 insertion accumulators and with valve port and seal; 3. push said air bag 3 gently after sealed mouth 4 inserts valve port, the air pressure that shows until said rain glass is 36Kpa, stops extruding again; 4. observe the air pressure 3~5 seconds on the said rain glass, this battery is qualified if air pressure does not descend then, directly gets into step 6.; 5. continue test if get into step like general who has surrendered under the air pressure; 5. remaining several single lattice is blocked, proceeded test, judgement is collaborated or is leaked gas; 6. take off sealed mouth 4 and carry out next monomer test.
In sum, this device has air bag 3, tensimeter 1, three-way connection 2 and sealed mouth 4 to be connected through flexible pipe 5 to constitute, and this device is made simple; Input cost is low; Operate also fairly simplely, be applicable to that the impermeability of pet-valve control sealed lead acid battery detects, prevent that the bad battery of sealing property from flowing into next operation and the quality that influences battery; Detect through tensimeter, its gas leak phenomenon is easy to detect through tensimeter.
The above embodiment has only expressed the part embodiment of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with accompanying claims.
