1、Designation: F1750 11 (Reapproved 2015)F1750 16 An American National StandardStandard Specification forPaintball Marker Threaded-Propellant Source Interface1This standard is issued under the fixed designation F1750; the number immediately following the designation indicates the year oforiginal adopt
2、ion or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the male and female threaded connectors used to
3、 interface a propellant source with a normalworking output pressure of 10 342 kPa (1800 psig) or less to a paintball marker.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.1.3 This standard does not purport to address all of
4、the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.

15、ibed by Dimensions C and K on Fig. 1.4.4 The male and female connectors shall not have any sharp edges or hanging burrs.All sharp edges will be broken R.38 MAX(R.015 MAX).5. Performance5.1 The interface is intended for use with compressed air, gaseous nitrogen, or CO2.5.2 The maximum operating press
16、ure of the interface is 10 342 kPa (1800 psig).5.3 The maximum allowable leakage at 10 342 kPa (1800 psig) is 0.1 cm3/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 pre
17、ssurized, together they shall meet the maximum leakagespecification.6. Physical Envelope6.1 The male connector shall 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 contai
18、n, as a means of propellant shutoff, a valve core to provide for an automatic shutoff of flowat the time of disconnection. 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
19、 valve core has been depressed 1.78 mm (0.070in.) from the surface designated as Datum B in Fig. 1. The stem of the 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 the
20、male connector which will interfere with the valve opening feature of the female fitting.8. Venting8.1 The female connector shall have a provision for the self venting of residual gas pressure prior to the disconnection of thethreaded interface.
