How does the Lead-Acid Battery Safety Valve detect the internal pressure of the battery?

Lead-Acid Battery Safety Valve is an important part of the battery system. Its main function is to detect and manage the pressure inside the battery. This process is usually accomplished with a pressure relief device. A pressure relief device is a sophisticated mechanism, usually consisting of a sensitive spring and one or more sealed valves. When the internal pressure of the battery rises to a preset threshold, the pressure release device is activated, causing the valve to open, thereby releasing the pressure and preventing potential danger caused by excessive internal pressure in the battery.

Specifically, the working principle of a pressure relief device is based on the compression or deformation of a spring. The design of the spring is limited by a preset pressure threshold. When the internal pressure of the battery exceeds this threshold, the spring will be compressed or deformed by the pressure. This change causes a valve connected to a spring to open, allowing gases inside the battery to escape, reducing pressure. Some advanced safety valves may also be equipped with a pressure sensor to monitor changes in the internal pressure of the battery. When the pressure sensor detects that the pressure exceeds a preset threshold, it sends a signal to the control system, which activates the pressure relief device.

Safety valves of this design are highly reliable and precise. They can accurately detect changes in battery internal pressure and release the pressure promptly when necessary to prevent potential dangers caused by overpressure. In addition, the structural design of this device is also very precise, ensuring that it works stably and reliably under various environmental conditions.

In practical applications, Lead-Acid Battery Safety Valve plays an important role in protecting battery systems and equipment. By promptly detecting and releasing the internal pressure of the battery, they ensure that the battery system can operate safely and reliably under various operating conditions. This is especially important for lead-acid batteries, which are widely used in various fields, such as automobiles, UPS systems, solar energy storage systems, and more.
