摘　　要：从金属密封副的密封机理出发,对密封的必要条件进行了分析,设计出了大流量的阀座组件。并提出了合理的工艺保证阀座组件的加工,解决了高压条件下大流量阀座组件的密封不良问题。经过实验验证了设计的正确性和工艺的可行性,为减压阀结构密封的可靠性保障以及合理工艺的正确选用提供了依据。Based on the sealing mechanism of the metallic sealing and the large flow valve components were designed. The reasonable pair, the necessary conditions of sealing were analyzed technique was presented to ensure the manufacturing quality of valve components and sealing failure problem was solved in The experiments confirmed the validity of the new design scheme and quired results in the experiment provide the basis for the guarantee of processing technique. large flow valve components under high-pressures. the feasibility of the processing technique. The acsealing reliability and the correct selection of proper
