摘要(Abstract):
介绍了一种能直接以海淡水作为工作介质的水压减压阀,针对其泄漏、气蚀拉丝侵蚀和污染等技术问题,提出了相应的解决措施。试验研究表明,该阀的性能指标满足了使用要求,其研究结果对于其它类型的水压阀的研制具有借鉴意义。
The working principle,key technological problems and their countermeasures,and experimental results of a kind of pressure reducing valves using seawater or tap water as well as other low fluids of low viscosity as the working media is introduced.
