The role of lead-acid battery safety valve

As a mature battery technology, lead-acid batteries are widely used in vehicle starting, UPS systems, solar energy storage and other fields. However, due to chemical reactions inside the battery, especially the gas generated during the charging process, the pressure inside the battery may increase, thereby creating potential safety risks. The design and implementation of lead-acid battery safety valves play a vital role in this regard.
Gas generation inside lead-acid batteries
During the charging process of lead-acid batteries, the water decomposition reaction causes the generation of hydrogen and oxygen, which is expressed as the following electrochemical reaction:
PbO2 + 4H+ + SO4^2- + 2e- → PbSO4 + 2H2O + O2
If the hydrogen and oxygen produced by this reaction, especially hydrogen, accumulate too much in the battery and cannot be released in time, it will cause the internal pressure of the battery to increase, which may lead to serious consequences such as explosion.
Basic principles of safety valves
A lead-acid battery safety valve is a device designed to control and maintain the pressure inside the battery. The basic principle is that when the internal pressure of the battery rises to a set safety level, the safety valve will automatically open to release the gas accumulated inside to prevent the battery from overheating and overpressure.

The importance of preventing battery explosions

Battery explosions can cause serious personal injury and property damage, so preventing such accidents is one of the top priorities of battery design. The role of the safety valve in this regard is to release gas promptly and effectively when an abnormal situation occurs inside the battery, to prevent excessive pressure and slow down or avoid the occurrence of battery explosion.
Types and selection of safety valves
There are many types of safety valves, including mechanical safety valves, electronic safety valves, and pressure relievers. Choosing an appropriate safety valve depends on the battery's application scenario and performance requirements. For example, for applications with extremely high safety requirements such as electric vehicles, more advanced electronic safety valves are usually chosen.
Performance and maintenance of lead-acid battery safety valves
As a common battery technology, lead-acid batteries play an important role in various applications. In order to ensure the safety and reliability of the battery, the safety valve is an indispensable component.
The importance of safety valve performance
The function of the safety valve in lead-acid batteries is mainly to control the release of gas inside the battery to maintain appropriate internal pressure. Its performance is directly related to the safety and life of the battery. Here are some key performance indicators:
Sensitivity: The safety valve should be able to quickly and accurately sense changes in pressure inside the battery. A highly sensitive safety valve can respond more promptly to abnormal conditions inside the battery.
Reliability: A safety valve should maintain reliable performance throughout its design life. This includes ensuring the normal opening and closing of the valve and preventing mis-opening or mis-closing.
Adaptability: Different application scenarios have different performance requirements for safety valves. In some special environments, such as high temperature and high humidity, safety valves need to have stronger adaptability.
The need for regular maintenance
To maintain safety valve performance and extend its life, regular maintenance is crucial. Here are some common maintenance measures:
Regular Inspections: Check the appearance and structure of the safety valve to ensure there is no damage or corrosion. At the same time, check whether the opening and closing of the valve is normal to avoid safety hazards caused by valve failure.
Cleaning and replacement: Some dirt may be produced during battery operation, which may block the passage of the safety valve. Therefore, clean the safety valve regularly to ensure that the passage is clear. If damage is found during inspection, replace the damaged parts promptly.
Recalibration: Some advanced electronic safety valves may require periodic recalibration to ensure their sensitivity and accuracy. This can be done by a professional to ensure the accuracy of the calibration.
The meaning of preventive maintenance
In addition to regular maintenance, some preventive maintenance measures should also be taken to reduce the probability of safety valve failure. This includes:
Environmental control: When installing the battery, consider the surrounding environmental factors, such as temperature, humidity, etc. Proper environmental conditions can help slow down corrosion and wear of safety valves.
Operating specifications: The normal operation and maintenance of the battery are also closely related to the performance of the safety valve. Proper battery use and maintenance operations can reduce unnecessary pressure fluctuations and reduce the burden on the safety valve.
