摘　　要：深海宏生物培养釜是用于培养深海宏生物样品的装置,为了实现海底生物样品在生物采样器与深海宏生物培养釜之间的保压转移并培养,提出一种带有驱动机构的翻板密封阀机构,可满足高压转移和密封等功能;利用有限元软件ANSYS建立翻板密封阀二维有限元模型,研究不同结构参数对翻板密封阀初始密封性能的影响;通过分析密封圈等效应力和接触应力来表征翻板密封阀的密封性能,并对翻板密封阀结构参数进行优化。结果表明,密封圈材料硬度和沟槽深度对初始密封性能的影响较显著;当氟橡胶密封圈材料硬度为HA85,沟槽深度为2.75 mm、沟槽宽度为5 mm,沟槽形状选择矩形沟槽时,翻板密封阀机构可获得较好的密封效果。对深海宏生物培养釜进行保压性能和样品转移实验,结果表明,提出的翻板密封阀机构的保压实验压降率为1%,其在96 MPa的压力下能够实现可靠的密封和转移。Deep-sea macro-organism culture kettle is a device used to culture deep-sea macrobiological samples.In order to achieve the pressure-retaining transfer and culture of deep-sea macro-organism between the biological samples and the deep-sea macro-organism culture kettle,a flap sealing valve mechanism with driving mechanism was proposed,which can meet the functions of high-pressure transfer and sealing.The two-dimensional finite element model of the flap sealing valve was established by using the finite element software ANSYS,and the influence of different structural parameters on the initial sealing performance of the flap seal valve was studied.By analyzing the equivalent stress and contact stress of the sealing ring,the sealing performance of the flap sealing valve was characterized.The structural parameters of flap seal valve were optimized.The results show that the hardness of the sealing ring material and the depth of the groove have a significant impact on the initial sealing performance.When the hardness of fluororubber seal ring material is HA85,the groove depth and width is 2.75 mm and 5 mm respectively,and the groove shape is rectangular groove,the flap seal valve mechanism can achieve better sealing effect.The pressure-retaining performance and sample simulation transfer tests of deep-sea macro-organism culture kettle were conducted in the laboratory.The test results show that the pressure drop rate of the pressure-retaining test is 1%,indicating the proposed flap sealing valve mechanism can achieve reliable sealing and transfer at a pressure of 96 MPa.
