- 摘要:
- 流量调节阀运动件较多，工作环境压力<10-11Pa，流体润滑不适应该环境条件。阀芯与推进剂（N2O4和MON-1）接触，无成熟解决方案。本文提出的阀门运动件润滑方案，非接触介质运动件采用自润滑材料或固体润滑膜。阀芯润滑，提出了物理气象沉积类金刚石膜(DLC)、TiN-Au复合膜及单质纯金膜三种方案。通过试验研究，确定阀芯采用全新的润滑方式-离子镀金。
- Abstract:
- Since there are many movement components in the flow control valve which works in the pressure of less than 10-11 Pa, the liquid-lubrication is unsuitable for it. The valve pintle is marinated in the propellant (N2O4 and MON-1), so there is no mature solve scheme at present. In this paper, a lubrication scheme for the movement components of the valve is presented, in which the pairs of movement components that do not contact with propellant are made up of self-lubrication material or are wrapped up in a solid lubrication film; as for the the lubrication of the valve pintle, three methods are proposed such as physical vapor deposition diamond-like carbon (DLC) film, TiN-Au compound film and pure Au film. A brand-new ion-gilding scheme for the pintle lubrication was chosen according to the results of the tests and the comparison.
