只有按照工况正确选用胶管及接头，才能保证使用胶管的可靠性和经济性。
这些因素有：1．胶管尺寸胶管内径要适当。
管径过小会加大管路内介质的流速，使系统发热，降低效率，而且会产生过大的压力降，影响整个系统的性能。
若胶管采用管夹固定或胶管穿过钢板等间隔物时，也要注意胶管的外径尺寸。
2．工作压力资料中有关胶管的动态工作压力是指胶管在连续工作时允许的最高压力。
按照有关国际标准规定的液压胶管的安全系数，我们推荐的工作压力通常约为胶管最低爆破压力值的四分之一。
3．冲击压力和疲劳寿命胶管的选择是根据液压系统设计的最高压力值来确定的。
由于液压系统的压力值通常是动态的，有时会出现冲击压力，冲击压力峰值会大大高于系统的最高压力值。

ISO 2003 – All rights reserved v Foreword ISO the International Organization 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 has 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 InternationalElectrotechnical Commission IEC on all matters of electrotechnical standardization. International 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 member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 8434 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such pate nt rights. International Standard ISO 8434-1 was prepared 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 of ISO8434-1:1994 and ISO 8434-4:1996 which have been technically revised. ISO 8434 consists of the following parts under the general title Metallic tube connections for fluid power and general use: Part 1: 24° cone connectors Part 2: 37° flared connectors Part 3: O-ring face seal connectors — Part 5: Test methods for threaded hydraulic fluid power connections Part 6: 60° cone connectors and weld-on nipples with or withoutO-ring NOTE ISO 8434-5 will change its number to ISO 19879 when the revision is published. ISO/TC 131/SC 4 N 430 – ISO/CD 8434-1 – 2003-04-03 vi ?? ISO 2003 – All rights reserved Introduction In fluid power systems power is transmitted and controlled through a fluid liquid or gas under pressure within an enclosed circuit. In general applications a fluid may be conveyed under pressure. Components may be connected through their ports by connections connectors and conductors tubes and hoses. Tubes are rigid conductors hoses are flexible conductors. COMMITTEE DRAFT ISO/TC 131/SC 4 N 430 – ISO/CD 8434-1 – 2003-04-03 ?? ISO 2003 – All rights reserved 1 Metallic tube connections for fluid power and general use — Part 1: 24° cone connectors 1 Scope This part of ISO 8434 specifies the general and dimensional requirements for the design and performance of 24o cone connectors using cutting ring and O-ring seal cone referred to as DKO which are suitable for use with ferrous and non-ferrous tubes with outside diameters from 4 mm to 42 mm inclusive. These connectors are for use in fluid power and general applications within the limits of pressure and temperature specified in this part of ISO 8434. They are intended for the connection of plain end tubes and hose fittings to ports in accordance with ISO 6149-1 ISO 1179-1 and ISO 9974-1. See ISO 12151-2 for related hose fitting specification. NOTE 1 For new designs in hydraulic fluid power applications ports in accordance with ISO 6149-1 shall be used. See also 9.6. NOTE 2 For swivel ends for use in hydraulic fluid power applications O-ring seal cone types shall be used see Figure 2. 2 Normative references The following referenced documents are indispensable for the application of this part of ISO 8434.
