Small number of precision worm gears for production of fluid control valves

The Jiangsu Provincial Economic and Trade Commission and the Changzhou Municipal Bureau of Science and Technology recently organized domestic experts in gear manufacturing, testing, materials, and heat treatment to perform scientific and technological achievements on the “Small Modulus Precision Worm Gear for Fluid Control Valves” project of Changzhou Desheng Precision Transmission Co., Ltd. Identification. The appraisal experts believe that the main technical performance indicators of this product have reached the international advanced level. It is understood that the project is completely based on the United States standard AGMA2111-A98 development, has begun mass production, the main supplier of global fluid motion and control products, the United States FLOWSERVE and other companies, used in oil and gas pipeline control valves and other products.
Fluid control valves are the basic components of the oil, natural gas, chemical, and water industries. They often require high temperature/low temperature resistance, corrosion resistance, and high pressure resistance in order to adapt to a harsh working environment. In the fluid control valve, the small module precision worm gear is the core part to ensure its quality, requiring high precision, smooth meshing, good wear resistance and high transmission efficiency. For a long time, efficient and mass production of small module precision worm gears has always been a bottleneck restricting the development of high-end liquid control valves in China.
Changzhou Desheng Precision Transmission Co., Ltd. has a history of producing small module gears, tooth shafts and worm gears for more than ten years. In recent years, it has devoted itself to technological innovation and new product development. The products are positioned in high-end and special markets. The small module precision worm gear series product for fluid control valves is a new product that the company researched and developed in 2007. Its quality has been rigorously tested by the relevant national quality inspection agencies and the US FLOWSERVE company. To enable this product to meet the needs of domestic and foreign markets, Desheng Company has conducted technological transformation of the production line and currently has the ability to produce 50,000 sets of precision worm gears per year. This provides strong support for the development of high-end control valves in China.
