Safety Valve For Prismatic Power Lithium Battery

Our square power lithium battery safety valve has undergone strict quality inspection and testing to ensure that its performance fully meets the design requirements. During the design process of the safety valve, we fully considered the pressure change inside the battery and different working environments to ensure that it can function reliably under various conditions. We provide a variety of specifications and models of safety valves to meet the individual needs of different square-power lithium batteries and ensure the correct adaptation and application of each safety valve in the battery system. You can choose our safety valve with confidence to provide all-around protection and reliability for your power lithium battery system.

• Valve Body: The main housing of the safety valve, which contains the internal components and is responsible for releasing excess pressure when necessary.
• Spring: The spring provides the necessary force to keep the valve closed under normal operating conditions. When the internal pressure exceeds the set threshold, the spring compresses, allowing the valve to open and release pressure.
• Disc: The disc is the movable part of the safety valve that opens and closes to control the flow of gases or fluids. It is connected to the spring and moves in response to changes in pressure.
• Adjusting Screw or Nut: This component allows for the adjustment of the valve's set pressure. By turning the adjusting screw or nut, the force exerted by the spring can be increased or decreased, thereby changing the pressure at which the valve opens.
• Seat: The seat is the sealing surface against which the disc rests when the valve is closed. It ensures a proper seal to prevent any leakage when the valve is in the closed position.
• O-ring or Gasket: To provide additional sealing, an O-ring or gasket is often used between the valve body and the seat to prevent any potential leakage.
• Vent or Outlet: This is the opening through which excess pressure is released when the valve opens. It allows gases or fluids to escape safely and prevent the over-pressurization of the lithium battery.

• Material Selection: Select high-quality materials, usually including stainless steel or other suitable materials, to ensure corrosion resistance, strength, and stability of the valve.
• Processing preparation: Cut the raw material into appropriate size for subsequent processing.
• Parts processing: According to the design requirements of the valve, use advanced processing equipment and technology to carry out precision processing on various parts, such as processing valve body, spring, valve cover, adjusting nut, etc.
• Assembly: Assemble the processed parts to ensure the normal operation of the valve. During assembly, care must be taken to ensure the exact position and tightness of each component.
• Debugging and testing: After the assembly is completed, the safety valve is strictly debugged and tested to ensure that the performance of the valve and the pressure release setting value meet the requirements. Testing may include pressure testing, leak testing, etc.
• Surface treatment: Treat the surface of the safety valve, such as spraying, polishing, etc., to improve the appearance quality and corrosion resistance.
• Quality inspection: Carry out a comprehensive quality inspection on the final product to ensure that each safety valve complies with product standards and specifications.
• Packing and delivery: Pack qualified safety valves and conduct a final quality inspection before delivery to customers or distributors.
