This utility model relates to an injection device, specifically a high-pressure airless sprayer with an improved inlet valve system. The invention focuses on enhancing the performance and efficiency of the valve mechanism used in diaphragm-type spray machines. The key components of the inlet valve include a valve body, a spring, a valve core, and a valve seat. One end of the spring is fixed to the valve body, while the other end is in contact with the valve core. The valve core is designed as a ball-type check valve, which ensures a tight seal when closed and allows smooth flow when open.
The design offers several advantages. Its simple structure reduces manufacturing complexity and maintenance requirements. The large inlet cross-sectional area minimizes flow resistance, enabling faster response times and improved paint delivery efficiency. Additionally, the use of a ball-type valve core significantly reduces wear compared to traditional designs, leading to longer service life and greater reliability.
The valve core is precisely matched with the opening of the valve seat, ensuring a secure and efficient sealing mechanism. This feature not only enhances the performance of the sprayer but also contributes to more consistent and uniform paint application. The overall design is particularly suitable for high-pressure environments where durability and precision are essential.
This patent introduces an innovative approach to improving the functionality of airless spray systems, making it a valuable contribution to the field of industrial painting and coating technologies. It provides a practical solution to common issues such as clogging, leakage, and inefficient paint flow, offering users a more reliable and effective tool for their applications.
