Double Breakthroughs in the Technologies of Enclosures and Valves: A New Domestic Benchmark Emerges in the Field of Fluid Control

Recently, news of a technological breakthrough has emerged in the field of fluid control in our country. A certain manufacturing enterprise has simultaneously overcome the core technologies of high-pressure box casting process and intelligent control valves, breaking the monopoly of foreign brands. The new products have been applied to the core equipment in the petrochemical field. According to the testing by a third party, the pressure-bearing capacity of the box reaches 45MPa, and the response speed of the control valve has been increased to 80ms, with the comprehensive performance reaching the international advanced level. "The collaborative innovation between the box and the valve is the key." The person in charge of the research and development introduced that traditional cast boxes have defects such as shrinkage cavities and inclusions. The team adopted the vacuum differential pressure casting technology and optimized the design of the runner with the help of simulation, increasing the compactness of the internal structure of the box by 30%. "This is equivalent to creating a 'diamond base' for precision valves." In terms of valve technology, the enterprise has broken through the design challenges of the multi-stage pressure reduction structure. By reconstructing the flow channel through the topology optimization algorithm and matching it with ceramic sealing components, the valve can achieve zero leakage under high-pressure differential working conditions. "We have developed an adaptive control algorithm that can automatically adjust the opening degree according to the characteristics of the medium." The engineer demonstrated that this valve product can still maintain a regulation accuracy of ±1% in a low-temperature environment of -40℃. The market feedback is positive. A certain petrochemical enterprise reported that after adopting the combination of domestic boxes and valves, the equipment failure rate has decreased by 65%, and the maintenance cost has been reduced by 40%. "Especially the reliability of the emergency shut-off valve has given us the confidence to replace imported equipment with domestic ones." The equipment supervisor said that this marks an important step in the localization of the core components of the key process industries in our country. Industry experts analyze that with the growth of demand in fields such as new energy and environmental protection projects, the market for high-precision boxes and intelligent valves is expected to enter a period of rapid growth. It is estimated that within five years, the domestic market share will increase from the current 35% to more than 60%, driving the output value of the relevant industrial chain to exceed 50 billion yuan. The enterprise has already launched the second-phase production expansion plan and is simultaneously building a digital testing center. "We will continue to deeply engage in materials science and control algorithms, and promote the evolution of box and valve technologies towards higher parameters and broader application scenarios." The person in charge said that this will provide key support for national strategic fields such as intelligent manufacturing and deep-sea engineering.
