The precision of the precision thread cartridge valve refers to the processing accuracy and precision fit of the thread to ensure the normal operation and sealing performance of the valve. The following are some key measures to ensure the precision of precision threaded cartridge valves.
Material selection: The selection of high-quality materials is the basic requirement to ensure the precision of the screw cartridge valve. Commonly used materials are stainless steel, copper, aluminum and its alloys. These materials should have good mechanical properties and corrosion resistance, and are not easy to deform and wear during processing.
Design optimization: Using reasonable structure and design can improve the accuracy of the threaded cartridge valve. For example, by increasing the radial axial clearance of the thread, the bearing capacity and reliability of the thread can be improved. At the same time, the structural design is optimized to reduce the volume and weight while improving the stiffness and stability.
Processing technology: The processing process of precision threaded cartridge valve is very important. The processing technology usually used includes turning, milling, threading, etc. In the processing process, it is necessary to use high-precision processing equipment and tools, such as CNC machine tools and five-axis machining centers, to ensure the accuracy and quality of the threads. At the same time, it is also necessary to use appropriate tools and cutting parameters to ensure cutting quality and processing efficiency.
Inspection method: In order to ensure the quality of precision threaded cartridge valves, it is necessary to use appropriate inspection methods for inspection. Common inspection methods include optical projector, coordinate measuring instrument, image measuring instrument and so on. These inspection equipment can quickly and accurately detect the size and shape of the thread to ensure the accuracy and fit of the thread.
Quality control: In order to ensure the precision of precision threaded cartridge valves, it is necessary to establish a strict quality control system. Including raw material inspection, processing control, finished product inspection, etc. In the manufacturing process, it is necessary to record and trace each process, and deal with and adjust problems in time. At the same time, regular internal and external audits are also required to ensure the effective operation of the quality management system.
In short, to ensure the precision of precision threaded cartridge valves needs to be comprehensively considered from the aspects of material selection, design optimization, processing technology, inspection methods and quality control. Through reasonable process flow and strict quality management, the high precision and reliability of the screw cartridge valve can be ensured to meet the needs of users.
