19、s 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 has the right to be represe
20、nted 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. International Standards are d
21、rafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International
22、Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 6149-1 was prepa
23、red by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 4, Connectors and similar products and components.This second edition cancels and replaces the first edition (ISO 6149-1:1993), which has been technically revised. ISO 6149 consists of the following parts, under the general
24、title Connections for hydraulic fluid power and general use Ports and stud ends with ISO 261 metric threads and O-ring sealing: Part 1: Ports with truncated housing for O-ring seal Part 2: Dimensions, design, test methods and requirements for heavy-duty (S series) stud ends Part 3: Dimensions, desig
25、n, test methods and requirements for light-duty (L series) stud ends Part 4: Dimensions, design, test methods and requirements of external and internal hexport plugsEN ISO 6149-1:2007ivIntroduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure
26、within an enclosed circuit. In general applications, a fluid (liquid or gas) may be conveyed under pressure. Components are connected through their threaded ports by fluid conductor connectors to tubes and pipes or to hose connectors and hoses. Ports are an integral part of fluid power components, s
27、uch as pumps, motors, valves, cylinders, etc. For threaded ports and stud ends specified in new designs in hydraulic fluid power applications, ISO/TC 131/SC 4 recommends that the ISO 6149 series be used because these International Standards specify ports and stud ends with metric threads and O-ring
28、sealing and because the subcommittee would like to help users by recommending one preferred system. ISO/TC 131/SC 4 further recommends that threaded ports and stud ends in accordance with the ISO 1179 series, ISO 9974 series and ISO 11926 series not be used for new designs in hydraulic fluid power a
29、pplications; these International Standards are maintained because they specify ports and stud ends that are currently used in hydraulic systems worldwide. EN ISO 6149-1:20071Connections for hydraulic fluid power and general use Ports and stud ends with ISO 261 metric threads and O-ring sealing Part
30、1: Ports with truncated housing for O-ring seal 1 Scope This part of ISO 6149 specifies dimensions for metric ports for use with the adjustable and non-adjustable stud ends detailed in ISO 6149-2 and ISO 6149-3. Ports in accordance with this part of ISO 6149 may be used at working pressures up to 63
31、 MPa 630 bar1) for non-adjustable stud ends and 40 MPa (400 bar) for adjustable stud ends. The permissible working pressure depends upon port size, materials, design, working conditions, application, etc. See ISO 6149-2 and ISO 6149-3 for pressure ratings. Users of this part of ISO 6149 should ensur
32、e that there is sufficient material around the port to maintain the pressure. NOTE The Introduction of this part of ISO 6149 gives recommendations for ports and stud ends to be used for new designs in hydraulic fluid power applications. 2 Normative references The following referenced documents are i
