Performance5.1The interfac
16、e is intended for use with CO5.1 The interface is intended for use with compressed air, gaseous nitrogen, or CO2compressed air or gaseous CO2, or both. .5.2 The maximum operating pressure of the interface is 10 342 kPa (1800 psig).5.3 The maximum allowable leakage at 10 342 kPa (1800 psig) is 0.1 cm
17、3/min.5.4 The male connector shall incorporate a means for propellant shutoff that shall meet the maximum leakage requirement.5.5 When the male and female connectors are joined and pressurized, together they shall meet the maximum leakagespecification.6. Physical Envelope6.1 The male connector shall
18、 conform to the physical envelope described in Fig. 1.6.2 The female connector shall conform to the physical envelope described in Fig. 2.7. Valve Core7.1 The male connector may contain, as a means of propellant shutoff, a valve core to provide for an automatic shutoff of flowat the time of disconne
19、ction. The stem of the valve core shall not protrude beyond the face of the male connector, that surfacedesignated as Datum B in Fig. 1. Full flow must be achieved when the stem of the valve core has been depressed 1.78 mm (0.070in.) from the surface designated as Datum B in Fig. 1. The stem of the
20、valve core shall be able to be depressed to a minimum depthof 2.54 mm (0.100 in.) below Datum B without being damaged. If a valve core is not used there shall not be any feature of themale connector which will interfere with the valve opening feature of the female fitting.8. Venting8.1 The female co
21、nnector shall have a provision for the self venting of residual gas pressure prior to the disconnection of thethreaded interface. Fig. 2 (Dimensions D and H) shows a recommended location and feature size for a vent hole.9. Operating Temperatures9.1 The interface shall have an operating range from 40
22、 to + 54C (40 to + 130F).Dimension SI InchesA f22.86 min f0.900 minB f18.46/17.02 f0.727/0.670C f14.66 6 0.08 f0.5776 0.003D R.25 6 0.13 R.010 6 0.005E f17.60/17.40 f0.693/0.685F 16.66 min 0.656 minG 6.35 6 0.13 0.250 6 0.005H 2.54 6 0.5 0.100 6 0.020J 1.02 6 0.13 0.040 6 0.005K 2.16 6 0.08 0.085 6
