阀芯阀套是一种用于流体流动的关键零件，通常由金属材料制成，具有耐高压、耐腐蚀和耐磨损的特性。它通常被安装在阀门内部，通过旋转或移动来流体的流量和方向。阀芯阀套在工业生产、水处理、石油化工等领域广泛使用。

What is a valve core and sleeve (中英文）explanation

A valve core and sleeve is a critical component used to control the flow of fluids. It is typically made of metal material and has the characteristics of high pressure resistance, corrosion resistance, and wear resistance. It is usually installed inside a valve and controls the flow rate and direction of fluids by rotating or moving. Valve cores and sleeves are widely used in industries such as industrial production, water treatment, and petrochemicals.
