ValveSealing is one of the core elements of the design of Zhejiang Hongda Special Rubber Products Co., Ltd.'s HD-58 safety valve, with a bezel diameter and bonnet diameter of 35mm and a bezel thickness of 6.3mm. These designs ensure that the safety valve fits well and is in close contact with the battery. During installation, these dimensions can effectively prevent air and liquid leakage and ensure that the sealing performance inside the battery is not affected.
In addition, the spool diameter of the safety valve is 19.8mm, which matches the overall height to ensure the accuracy of the sealing surface between the spool and the outer ring. This accuracy ensures that the safety valve can continue to maintain good sealing even when the battery is frequently charged and discharged, without gas leakage or battery fluid overflow.
The sealing performance of Zhejiang Hongda Special Rubber Products Co., Ltd.'s HD-58 safety valve mainly depends on the design and material selection of its soft rubber seal. Although the specific upper and lower soft rubber diameters are not given in detail, it can be inferred that the safety valve uses highly elastic, pressure-resistant, and corrosion-resistant soft rubber materials. These materials have good sealing properties and can effectively prevent battery fluid leakage even under high pressure and high temperature environments, while preventing external contaminants such as moisture and dust from entering the battery system, thereby improving the safety of the battery.
The use of soft rubber seals can achieve precise pressure regulation during battery charging and discharging without affecting the flexibility of the valve. The elastic properties of this soft rubber ensure that the sealing effect is stable and reliable even after long-term use, and it is not easy to age or harden.
The waterproof function of the HD-58 safety valve is another highlight of its sealing design. In the use of modern cars, batteries are exposed to complex environments, including external contaminants such as rain, moisture, and dust. If there is no good waterproof sealing design, these contaminants may penetrate into the battery, causing battery short circuits, corrosion, and even damage to the battery. Therefore, the HD-58 safety valve uses high-quality waterproof materials and sealing designs, which can effectively prevent moisture from entering the battery and ensure that the battery system can still work normally under harsh conditions such as high humidity or rainy days.
The sealing design of the safety valve of Zhejiang Hongda Special Rubber Products Co., Ltd. not only provides excellent elasticity through soft rubber materials, but also prevents water vapor or other foreign substances from entering the valve body through a unique structure. Even when the working environment of the car is subject to frequent vibration or high temperature changes, the safety valve can still maintain excellent waterproofness and anti-pollution ability, ensuring the normal operation and service life of the battery.
As a safety valve designed for lead-acid battery systems, the material selection of the HD-58 safety valve is very important. Lead-acid batteries contain strong acid electrolytes, which are highly corrosive and easily corrode metal and rubber materials, affecting their service life and performance. In order to solve this problem, the HD-58 safety valve of Zhejiang Hongda Special Rubber Products Co., Ltd. uses acid-resistant rubber and corrosion-resistant metal materials to ensure that the various components of the safety valve can maintain good performance even in an environment of long-term contact with battery fluid.
These corrosion-resistant materials can effectively prevent the battery fluid from corroding the valve material, thereby extending the service life of the safety valve. In addition, the anti-aging properties of the material ensure that the sealing and pressure resistance of the valve will not decrease even in long-term use or high temperature environments, thereby ensuring the safety and reliability of the battery system in long-term use.
Zhejiang Hongda Special Rubber Products Co., Ltd.'s HD-58 safety valve not only has excellent sealing performance, but also has excellent pressure regulation function. In automotive start-stop batteries, frequent start-stop and battery charging and discharging processes will lead to the accumulation of internal gas, which may cause excessive internal pressure of the battery, leading to safety accidents. Zhejiang Hongda Special Rubber Products Co., Ltd.'s HD-58 safety valve also adopts a precise pressure regulation mechanism. When the internal pressure of the battery is too high, the safety valve can automatically open and quickly release excess gas to prevent the battery from bulging, rupture or explosion. At the same time, the valve can be quickly closed after the gas is discharged to avoid the risk of gas leakage or battery fluid leakage, further ensuring the sealing and safety of the battery system. This perfect combination of sealing and pressure regulation enables the HD-58 safety valve to maintain stable function.
