Abstract
The utility model discloses an accumulator safety valve pressure detecting device which comprises an electrical motor and an air cylinder which is connected with the electrical motor, wherein the air cylinder is communicated with the inner part of an accumulator by a connecting pipe which is connected with a pneumatic setting adjuster. The utility model also comprises a precision pressure gauge which is communicated with the inner part of the accumulator. The utility model adopts an automatic pressure making storage to make pressure automatically and carries out storing voltage regulating; the pneumatic setting adjuster precisely adjusts the pressure, and the outputted pressure is stable with a uniform speed; detecting data are displayed by the precision pressure gauge with scientific detection method and high detection efficiency; the artificial error is eliminate. Thus, the result of detecting is precise and the safety performance of the whole accumulator is reliable.
Description
[technical field]
The utility model relates to accumulator protection valve, particularly the detection of accumulator protection valve pressure.
[background technology]
Safety valve is the important component part of maintenance-free battery, plays a part quite crucially for the thermal runaway state of control accumulator, if the valve of opening of safety valve is pressed excessively, just can not in time discharge when then internal storage battery gas is full of, and causes thermal runaway easily; If the valve of opening of safety valve is pressed too smallly, then internal storage battery gas is discharged too much, causes dehydration easily.
So, be requisite important step in the accumulator production process to the detection of accumulator protection valve pressure.At present, accumulator production enterprise substantially all adopts the pressure of manually making to press to safety valve to detect, and this method efficient is very low, and the personal error of manually making pressure is bigger, measuring accuracy is poor, and it is bigger than normal to detect error, to whole accumulator security of products certain influence can be arranged.
So, how to adopt effective method to come pressure detection to accumulator protection valve, make detection method more science, detection efficiency is higher and the more accurate important topic that becomes accumulator production business research of testing result.
[summary of the invention]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of accumulator protection valve pressure-detecting device, detection method more science, detection efficiency is higher and testing result is more accurate.
For achieving the above object, the utility model proposes a kind of accumulator protection valve pressure-detecting device, comprise motor, the cylinder that links to each other with motor, cylinder communicates with the inside of accumulator by connecting pipe.
Further, on connecting pipe, also be connected with pneumatic setter.
Further, also comprise precision pressure gauge, described precision pressure gauge communicates with the inside of accumulator.
The beneficial effects of the utility model: the utility model employing is made the pressure memory storage automatically and is made pressure automatically and store pressure regulation, by pneumatic setter pressure is accurately regulated again, the pressure of output is at the uniform velocity stable, show by precision pressure gauge again and detect data, detection method is science more, and detection efficiency improves greatly, has thoroughly eliminated personal error, the result who detects is more accurate, makes the security performance of whole accumulator more reliable.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 represents the structural representation of the utility model accumulator protection valve pressure-detecting device.
[embodiment]
Be illustrated in figure 1 as the structural representation of the utility model accumulator protection valve pressure-detecting device.Comprise electrode 1, the cylinder 2 that links to each other with motor 1, cylinder 2 communicates with the inside of accumulator by connecting pipe 3.After motor 1 work air is pressed into cylinder 2, cylinder 2 has the effect of storage gas, the volume of cylinder 2 is decided as required, gas in the cylinder 2 enters the inside of accumulator by connecting pipe 3, on connecting pipe 3, be connected with pneumatic setter 4, the pressure of input accumulator is just more accurate, stable like this, also comprises a precision pressure gauge 5 that links to each other with the inside of accumulator, and precision pressure gauge 5 can be monitored the pressure of internal storage battery in real time.The pressure of manually making pressure originally is inhomogeneous, personal error is very big, air pressure output is unstable, the pressure precision of output is not high yet, but the accuracy of detection of accumulator protection valve pressure is required to reach 0.05kpa, and it is very low manually to make the efficient of pressure, can not meet the needs of production, of the present utility model making automatically presses precision to reach 0.05kpa, and improved detection efficiency, and the detection of an accumulator is only needed time about 0.5 minute.The utility model does not all have the requirement of feature to motor 1 and cylinder 2, only need common motor 1 and cylinder 2 to get final product, test process is simple, the method of testing science, the cost of realizing is also very low, but production efficiency is but improved a lot, and improved precision of test result widely, improved whole accumulator reliability of products.
Application of the present utility model is not limited to the detection of accumulator protection valve pressure, and other need need also can use the utility model to the device that pressure detects to battery or the employing similar structures that safety valve pressure detects.
