1、Designation: F1750 05 (Reapproved 2010)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 adoption or, i

2、n 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 threadedconnectors used to interface

3、 a propellant source with a workingpressure of 10 342 kPa (1800 psig) or less to a paintballmarker.1.2 The values stated in SI units are to be regarded asstandard. The values given in parentheses are for informationonly.1.3 This standard does not purport to address all of thesafety concerns, if any,

4、 associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Connector Gender Assignment3.1 The female connector is that connector which is config-ured as part of the paintball marker.3.2 The male connector is that connector which is config-ured as part of the propellant source.4. Materials and Manufacture4.1 The male and f

7、emale connectors shall be made frommaterials that are compatible with CO2. The materials andprocesses used to manufacture male and female connectorsshall result in items with mechanical strength sufficient to passa 20 684-kPa (3000-psig) proof pressure check without failureor any degradation to func

Valve Core7.1 The male connector may contain, as a means of propel-lant shutoff, a valve core to provide for an automatic shutoff offlow at the time of dis

16、connection. The stem of the valve coreshall not protrude beyond the face of the male connector, thatsurface designated as Datum B in Fig. 1. Full flow must beachieved when the stem of the valve core has been depressed1.78 mm (0.070 in.) from the surface designated as Datum B inFig. 1. The stem of th

17、e valve core shall be able to be depressedto a minimum depth of 2.54 mm (0.100 in.) below Datum Bwithout being damaged. If a valve core is not used there shallnot be any feature of the male connector which will interferewith the valve opening feature of the female fitting.8. Venting8.1 The female co

18、nnector shall have a provision for the selfventing of residual gas pressure prior to the disconnection ofthe threaded interface. Fig. 2 (Dimensions D and H) shows arecommended location and feature size for a vent hole.9. Operating Temperatures9.1 The interface shall have an operating range from 40to

19、 + 54C (40 to + 130F).10. Flow10.1 The interface shall flow not less than 170 sL/min at 689kPa (6 S.C.F.M. at 100 psid).10.2 The feature allowing flow through the female connec-tor shall lie within the area designated by minimum DimensionMinFig. 2.10.3 The feature allowing flow through the male conn

20、ectorshall lie within the area designated by Dimension M in Fig. 1.11.
