Abstract
The utility model relates to the measurement mechanism of safety valve opening-closing pressure in a kind of different air pressure environment, the tensimeter one comprise transparent sealing chamber, being connected by stop valve one with transparent sealing chamber, the vacuum pump be connected with transparent sealing chamber by stop valve two, the tracheae one and tracheae two that are connected with the battery case with safety valve is respectively provided with in transparent sealing chamber, be connected with tensimeter two by stop valve three after tracheae one stretches out transparent sealing chamber, be connected with air compressor by stop valve four after tracheae two stretches out transparent sealing chamber.The utility model energy simulated battery in different air pressure environment (on the Qinghai-Tibet Platean as 3000-4000 rice) use time, the service condition of safety valve in battery, the opening-closing pressure value of safety valve.
Description
Technical field
The utility model relates to battery test apparatus, is specifically related to the measurement mechanism of safety valve opening-closing pressure in a kind of different air pressure environment.
Background technology
Safety valve is a vitals of accumulator, when pressure in cell batteries exceedes normal working inner pressure, it can open to reduce interior pressure in a controlled manner, and this mechanism can make inner pressure of battery out and away lower than the pressure that can damage battery case, and air can not be made to enter.
At present, accumulator protection valve mainly use design for the mountain area of plains region or low altitude area height.But for High aititude height (Qinghai-Tibet Platean as 3000-4000 rice sea level elevation), can accumulator protection valve normally work, and in this kind of atmospheric pressure environments the unlatching situation etc. of safety valve, for storage battery production enterprise, especially be intended to be the enterprise that above-mentioned high altitude localities provides accumulator product, need high spot reviews.
Utility model content
For above-mentioned present situation, the utility model provides the measurement mechanism of safety valve opening-closing pressure in a kind of different air pressure environment, this device energy simulated battery in different air pressure environment (on the Qinghai-Tibet Platean as 3000-4000 rice) use time, the service condition of safety valve in battery, the opening-closing pressure value of safety valve.
The technical solution of the utility model is achieved in that the measurement mechanism of safety valve opening-closing pressure in a kind of different air pressure environment, comprise transparent sealing chamber, by the tensimeter one that stop valve one is connected with transparent sealing chamber, by the vacuum pump that stop valve two is connected with transparent sealing chamber, the tracheae one and tracheae two that are connected with the battery case with safety valve is respectively provided with in transparent sealing chamber, be connected with tensimeter two by stop valve three after tracheae one stretches out transparent sealing chamber, be connected with air compressor by stop valve four after tracheae two stretches out transparent sealing chamber.
Transparent sealing chamber of the present utility model also can be provided with air intake duct, and air intake duct is communicated with transparent sealing chamber by stop valve five.
The utility model energy simulated battery in different air pressure environment (on the Qinghai-Tibet Platean as 3000-4000 rice) use time, the service condition of safety valve in battery, the opening-closing pressure value of safety valve.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the enlarged drawing at I place in Fig. 1.
Embodiment
See accompanying drawing 1-2, the utility model comprises transparent sealing chamber 1, by the tensimeter 1 that stop valve 1 is connected with transparent sealing chamber 1, by the vacuum pump 13 that stop valve 27 is connected with transparent sealing chamber 1, be provided with in transparent sealing chamber 1 tracheae 1 and tracheae two 12(tracheae 1 that are connected with the battery case 2 with safety valve 10 respectively and tracheae 2 12 respectively with battery case 2 inner space), be connected with tensimeter 29 by stop valve 38 after tracheae 1 stretches out transparent sealing chamber, be connected with air compressor 14 by stop valve 44 after tracheae 2 12 stretches out transparent sealing chamber 1, transparent sealing chamber is provided with air intake duct 15, and air intake duct 15 is communicated with transparent sealing chamber 1 by stop valve 53.
The utility model adopts said structure, during use, the single lattice be provided with in the battery case 2(battery case 2 of safety valve 10 are interconnected by punching) directly put into transparent sealing chamber 1, tensimeter 1 is connected by stop valve 1 with transparent sealing chamber 1, measure the pressure in transparent sealing chamber 1, vacuum pump 13 is connected with transparent sealing chamber 1 by stop valve 27, in transparent sealing chamber 1, manufacture different vacuum tightness.
Tensimeter 29 is connected with stop valve 38, directly measures the opening-closing pressure value of battery case 2 internal safety valve 10, by opening the stop valve 44 of connection air compressor 14 and being pressurizeed to battery case by stop valve 44 control air inflow.
Stop valve 53 just, after test terminates, allows air enter in transparent sealing chamber 1.
Test process is take out different vacuum tightness with the opening-closing pressure of test safety valve under different vacuum tightness to vacuum tank.
Claims (2)
1. the measurement mechanism of safety valve opening-closing pressure in a different air pressure environment, it is characterized in that: the tensimeter one comprise transparent sealing chamber, being connected by stop valve one with transparent sealing chamber, the vacuum pump be connected with transparent sealing chamber by stop valve two, the tracheae one and tracheae two that are connected with the battery case with safety valve is respectively provided with in transparent sealing chamber, be connected with tensimeter two by stop valve three after tracheae one stretches out transparent sealing chamber, be connected with air compressor by stop valve four after tracheae two stretches out transparent sealing chamber.
2. measurement mechanism according to claim 1, is characterized in that: transparent sealing chamber is provided with air intake duct, and air intake duct is communicated with transparent sealing chamber by stop valve five.
