2 Requirements

2.1 connector with the size Part liquid oxygen filling joints shall be capable of mating with the ground part. Joint with the size and structure of the ground section shall comply with Figure 1 and Table 1 Provisions. Note 1. The valve spring seal means having the following properties can be used a pressing position in the axial direction. a) spring stiffness for each force-displacement 10N 1.3mm ± 0.29mm (per 1bf displacement 0.0228in ± 0.005in); b) in the fully engaged position, the ends of the sealing area should be in all positions on the X dimension, that is, from 10.1mm to 25mm (0.398in to 0.985in) in the range of air tight, and when an X dimension of 12mm (0.47in) when, at the joint portion of the machine should 22.2daN ± 2.2daN (50lbf ± 5lbf) clamping force. When X in any of its value within the allowable range, the pressing force should not exceed 35.6daN (80lbf); c) 12.7mm (0.5in) contact points sealing means for the realization of this intention and assumes standard measure diameter; d) sealing the area between the diameter d2 and d4. Note 2.
