Fluid control valves are the basic components of the petroleum, natural gas, chemical, and water industries. They are often designed to withstand high temperatures/low temperatures, corrosion, and high pressure to meet the harsh working environment. In the fluid control valve, the small modulus precision worm pair is the core part to ensure its quality, requiring high precision, stable meshing, good wear resistance and high transmission efficiency. For a long time, the high-efficiency mass production of small-modulus precision worm pairs has been a bottleneck restricting the development of high-end liquid control valves in China.
Changzhou Dehao Precision Transmission Co., Ltd. has a history of producing small modulus gears, pinions and worm gears for more than ten years. In recent years, it has been committed to technological innovation and new product development. The products are positioned in the high-end and special markets. The small modulus precision worm pair series for fluid control valves is a new product developed by the company in 2007. Its quality has been rigorously tested by relevant national quality inspection agencies and FLOWSERVE. In order to meet the needs of the domestic and international markets, Dexter has carried out technical transformation of the production line, and now has the ability to produce 50,000 sets of precision worm pairs per year. This provides strong support for the development of high-end control valves in China.
system, and also can be used to transport other kinds of viscosity liquid, such as water, oil, slurry, corrosive or liquid with small solid particles
Fluid control valve made a breakthrough with the development of small modulus precision worm pair
The Jiangsu Provincial Economic and Trade Commission and the Changzhou Municipal Science and Technology Bureau have organized experts in the field of gear manufacturing, testing, materials and heat treatment to carry out scientific and technological achievements on the project of “small modulus precision worm pair for fluid control valves†of Changzhou Dehao Precision Transmission Co., Ltd. Identification. The appraisal experts believe that the main technical performance indicators of the product have reached the international advanced level. It is understood that the project is completely developed according to the American standard AGMA2111-A98. At present, it has started mass production, and is mainly used by companies such as FLOWSERVE, a giant of global fluid motion and control products, for oil and gas pipeline control valves and other products.
