船用海水安全阀的改进研究

Research of seawater safety valve's improvement

分析了某型船用海水安全阀在使用过程中存在密封面泄漏、回座压力不稳和材料易腐蚀等问题的原因。论述了更换阀体、密封面和弹簧的材料及阀门结构改进的试验结果。

It usually happened that the valve seat hops frequently, the sealing face life is so short, the material of valve body corrode easily. This topic analysis the reason about these probIems from the structure, material and action characteristic of the seawater safety valve, put forward the improved scheme. The result of experiment confirms that the new-type safety valve scheme is efficiency.
