针对稠油热采中缺少适用的高差压调节阀而难以实现科学注汽的现状，研制了迷宫式高差压调节阀。调节阀由阀体、阀芯、阀杆、密封填料仓和传动机构组成。阀门设计中突破了高差压必然导致高流速的传统设计观念，选择高阻力系数的阀芯作基本节流件构成流道曲折、多级降压和迷宫密封的结构，减小了高差压阀门的振动、冲蚀和噪声，并获得宽广的调节幅度。迷宫式高差压调节阀样机的流量-开度特性测试曲线与理论设计曲线基本一致，在稠油热采现场运行1～2年无任何故障，是适用于稠油热采配汽流量调节的理想调节阀。

Because of the lack of applicable high differential pressure regulating valves, scientific steam injection for thermal recovery of heavy oil cannot be realized at present. A high differential pressure regulating valve with labyrinth is developed thereby. The valve is comprised of valve body, valve core, valve rod, packing box and transmission device. In designing the valve, the traditional concept of high pressure drop of flow accompanied necessarily with high flow velocity is got rid of, and the valve core with high resistance coefficient is selected as throttling element to structure the valve with zigzag flow path, multiple pressure-drop part and labyrinth-like seal. These features lead to such advantages as wide regulation range, low leakage, low noise and smooth operation. Application shows the valve has good performance.
