通用和液压传动用连接件 带弹性体密封或金属对金属密封的ISO 228-1标准螺纹的孔口和螺柱端 第1部分：带螺纹的孔口 ISO 1179-1 - 2013
适用范围
This part of ISO 1179 specifies dimensions for ports with ISO 228-1 threads for use with non-adjustable stud ends described in ISO 1179-2, ISO 1179-3 and ISO 1179-4 and with adjustable stud ends described in ISO 1179-3.
Ports in accordance with this part of ISO 1179 are applicable for use with
— ISO 1179-2 heavy-duty (S series) stud ends with type E sealing at working pressures up to 63 MPa (630 bar) and light-duty (L series) stud ends at working pressures up to 25 MPa (250 bar),
— ISO 1179-3 light-duty (L series) stud ends with type G sealing at working pressures up to 31,5 MPa (315 bar) and ISO 1179-3 light-duty (L series) adjustable stud ends with type H sealing at working pressures up to 20 MPa (200 bar), and
— ISO 1179-4 stud ends with type B sealing at working pressures up to 40 MPa (400 bar) for the S series, up to 25 MPa (250 bar) for the L series, and up to 10 MPa (100 bar) for the LL series,
except for the G2 size port, which in hydraulic fluid power systems is used mainly with accumulators and for which ISO 1179-3 and ISO 1179-4 do not specify stud ends. The permissible working pressure depends upon size, materials, design, working conditions, application, etc.
Users of this part of ISO 1179 should ensure that there is sufficient material around the port to maintain the pressure.
NOTE The introduction of this part of ISO 1179 gives recommendations for ports and stud ends to be used for new designs in hydraulic and pneumatic fluid power applications.

①Size and dimensions in accordance with ISO 228-1. ②Type N corresponds to the spot face to be used with male stud end types B and E in ISO 1179-2 and ISO 1179-4. Type W corresponds to the spot face to be used with male stud end types G and H in accordance with ISO 1179-3. ③Given tap drill depths require the use of a bottoming tap to produce the specified full thread lengths. Where standard taps are used, increase tap drill depths accordingly. ④The G2 size port is used in hydraulic fluid power systems mainly in accumulators. ISO 1179-3 and ISO 1179-4 do not specify stud ends for the G2 size port. | |||||||||
