Extra-large diameter intelligent water inlet valve developed successfully

Abstract: Recently, the large-diameter intelligent water inlet valve has recently been successfully developed and manufactured by Hubei Hongcheng General Machinery Co., Ltd., and it has been used in domestic projects for pumped-storage power stations to contribute to the localization of major equipment valves.

A high-tech product that digests and absorbs advanced foreign technology, adopts a number of patented technologies, new materials, and new processes to replace imported products. It has broad market prospects and is widely used in pumped-storage power stations and high-head hydraulic power generation systems. Horizontal high-head pumped storage power station turbine--large-diameter intelligent water inlet valve has recently been successfully developed and manufactured by Hubei Hongcheng General Machinery Co., Ltd., and it has been used in domestic projects of pumped-storage power stations for localization of major equipment valves. Made a contribution.

The innovative technical features of the DN2500 large-diameter intelligent water-inlet ball valve developed by Hubei Hongcheng General Machinery Co., Ltd. are characterized by a number of plant simulations and the overall and detailed structure of the valve in the flow field of the valve under the most dangerous conditions. Force analysis; adopts stroke control and oil and water interlocking loop to avoid malfunction of valve; dynamic seal ring adopts constant ratio pressure and maintenance-free “L” sealing structure; symmetrical differential moving pressure double hard sealing structure The inspection seal has a reliable locking device; the shaft end seal adopts double compensated movement sealing structure, which has the function of preventing sediment from entering the bearing; adopts high-strength, maintenance-free, self-lubricating bearing for frequent starting and swinging servomotor with locking device; The operating system, as well as the use of isolated animal energy tanks to store energy and multiple protective structures to meet the automation needs; Recently this new product research project won the China Machinery Industry Science and Technology Award.
