During the use of lead-acid batteries, especially in high temperature, high humidity and harsh environments, how to effectively prevent the leakage of internal gas and the infiltration of external pollutants in the battery has become the key to improving battery safety. In order to meet this challenge, Zhejiang Hongda has comprehensively innovated the sealing structure of the HD-24 Large Diameter Waterproof Lead-Acid Battery Safety Valve, improving its sealing performance in high pressure, humid and harsh environments.
The sealing structure of the HD-24 safety valve adopts an optimized sealing ring. This design changes the shape, thickness and elastic material of the sealing ring to ensure that the contact between the sealing ring and the valve body is still tight even under extreme pressure conditions, eliminating the risk of gas leakage. Unlike the traditional single sealing ring design, the sealing ring of the HD-24 has been carefully designed to maintain high elasticity and sealing under different operating temperatures, humidity and pressures.
Especially during the charging and discharging process of lead-acid batteries, gas will be generated inside the battery. If the sealing design is not good, the gas will gradually accumulate and even cause explosion or battery expansion. The sealing ring of the HD-24 can effectively prevent the leakage of these gases and maintain a stable pressure inside the battery, thereby improving the safety and reliability of the battery.
Another important innovation of the HD-24 safety valve is its large diameter design, which not only enhances the gas discharge capacity but also improves the sealing performance. Lead-acid batteries will generate a certain amount of gas during use, which needs to be discharged through the safety valve to avoid excessive gas accumulation leading to battery rupture or other safety accidents. The large diameter valve port of HD-24 ensures that the gas can be discharged quickly and effectively, avoiding the potential safety hazards of the battery caused by gas blockage.
The advantage of the large diameter design is also reflected in the sealing effect. The increase in the valve port improves the uniformity and stability of the contact between the sealing ring and the valve body, thereby avoiding the possibility of sealing failure. Even under long-term high-pressure working conditions, the sealing ring of HD-24 can still maintain long-lasting sealing performance, ensuring that the gas will not leak and enhancing the safety of the battery under extreme working conditions.
The HD-24 safety valve adopts a multi-layer composite sealing structure. The innovation of this structure is that the sealing layers of different materials cooperate with each other and work together to enhance the sealing effect. In this design, each layer of sealing material plays a different role, with the inner sealing layer responsible for the tight isolation of the gas, and the outer sealing layer protecting the battery from the intrusion of external moisture, humidity or other contaminants.
This design effectively solves the problem that external moisture or contaminants may enter the battery through the valve. Especially in high humidity, high temperature or other harsh environments, the multi-layer composite sealing structure of HD-24 can always maintain the sealing of the battery, prevent moisture or impurities from affecting the inside of the battery, reduce the occurrence of battery aging, corrosion and other problems, and improve the service life of the battery.
In the selection of sealing materials, the HD-24 safety valve uses highly adaptable materials, which have excellent high temperature resistance, low temperature resistance, aging resistance, chemical corrosion resistance and other characteristics. During the use of lead-acid batteries, especially under extreme conditions such as long-term high temperature, high humidity or cold start, traditional sealing materials may age or lose elasticity, thereby affecting the sealing effect.
The sealing material of HD-24 has strong weather resistance and can maintain long-term stable sealing performance under different temperatures, humidity and external environmental changes. Whether in extremely cold winter or hot summer, HD-24 can ensure the sealing of the battery under various climatic conditions, thereby ensuring the safety and stable operation of the battery.
The sealing structure design of the HD-24 safety valve relies not only on innovative ideas, but also on Zhejiang Hongda's precise manufacturing process. Each HD-24 safety valve undergoes strict quality control and precision manufacturing to ensure that the matching accuracy between the sealing ring and the valve body reaches the industry-leading level. The precise manufacturing process ensures the smoothness of the sealing surface, the elasticity of the sealing ring, and the contact accuracy between the valve body and the sealing ring, so that each safety valve has an excellent sealing effect.
