26、on for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established ha
27、s the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Inte
28、rnational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the m
29、ember bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 15761 was prepared by Technical
30、 Committee ISO/TC 153, Valves, Subcommittee SC 1, Design, manufacture, marking and testing. Annexes A, B and C form a normative part of this International Standard. Annexes D and E are for information only. ENISO15761:2002 v Introduction The purpose of this International Standard is to establish bas
31、ic requirements and practices for socket-welding, butt- welding, threaded and flanged end, steel gate, globe and check valves with reduced body seat openings, whose general construction parallels that specified by the American Petroleum Institute standard API 602 1and the British Standard BS 5352 2
32、. The form of this International Standard corresponds to ISO 6002 3and ISO 10434 4 . However, it is not the purpose of this International Standard to replace ISO 6002, ISO 10434 or any other International Standard not identified with petroleum or natural gas industry applications.

33、ETNIITOTS LANDNADRA ISO 67512002:1)E( Steel gate, globe and check valves for sizes DN 100 and smaller, for the petroleum and natural gas industries 1 Scope This International Standard specifies the requirements for a series of compact steel gate, globe and check valves for petroleum and natural gas
34、industry applications. It is applicable to valves of nominal sizes DN 8, 10, 15, 20, 25, 32, 40, 50, 65, 80 and 100, corresponding to nominal pipe sizes NPS , , , , 1, , , 2, , 3 and 4, and to pressure designations of Class 150, Class 300, Class 600, Class 800 and Class 1500. Class 800 is not a list
35、ed class designation, but is an intermediate class number widely used for socket welding and threaded end compact valves. It includes provisions for the following valve characteristics: outside screw with rising stems (OS inside screw with rising stems (ISRS), in sizes and pressure designations of C
36、lass ; socket welding or threaded ends, in sizes and pressure designations of Class800 and Class 1500; flanged or butt-welding ends, in sizes and pressure designations of , excluding flanged end Class 800; bonnet joint construction bolted, welded, threaded with seal weld, and union nut for nominal p
37、ressure rating Class ; body seat openings; materials, as specified; testing and inspection. This International Standard is applicable to valve end flanges in accordance with ASME B16.5 and valve body ends having tapered pipe threads to ISO 7-1 or ASME B1.20.1. It is applicable to extended body const
38、ruction in sizesand pressure designations of Class 800 and Class 1500, and to bellows and bellows assembly construction as may be adaptable to gate or globe valves in sizes . It covers bellows stem seal type testing requirements. 2 Normative references The following normative documents contain provi
