摘　　要：本文介绍了一种新型的止回阀——非能动控制梭式止回阀,与旋启式止回阀在流体、结构原理、流阻系数、密封、启闭特性等方面进行比较,并对梭式止回阀进行了部分实验和仿真分析,得出梭式止回阀具有轴流对称、平衡绕流、低阻流线、启闭时间可调、多元密封、零泄漏、低噪音等优点,并成功应用在淮北国安电力有限公司的凝结水管路上。A novel check valve passive control shuttle-type check valve is introduced in this paper based on the comparison of the existing swing check valves including the liquid, structural principle, flow resistance coefficient, airproof and start-stop performances. The experimental and simulation analysis validates that shuttle-type check valve has the advantages of symmetric structure along the pipeline axis, balance circle flow, low coefficient streamline, adjustable start-stop time, muhi-airproof, zero leakage and less noise, successfully used in the condensate pipeline of Huaibei Guoan Power Co., Ltd.
