AI Technical Summary
Technical Problem
Existing steel brake cylinders are heavy and cannot meet the requirements for lightweight vehicles. Furthermore, the drain valve design is inconvenient to operate, and water vapor can easily splash onto the driver's hands.
Method used
The inner liner is made of PA material and the structure is made of glass fiber layer. The glass fiber layer is wound in both the circumferential and longitudinal directions. The drain valve is designed to drain from the side and uses a horizontal pull ring. The drain valve includes a valve seat, valve body, valve core, sealing ring and spring structure.
Benefits of technology
It achieves lightweight gas cylinders, enhances structural strength, resists corrosion, facilitates operation, and prevents water vapor from splashing onto hands.
