Introduction
Interpretation of the national standard GB/T 18364-2017 for liquefied petroleum gas filling ports for automobiles
Background and significance of standard formulation
GB/T 18364-2017 replaces the old versions GB/T 18364.1-2001 and GB/T 18364.2-2005, integrating the technical requirements for spiral and quick-insert filling ports. This standard mainly refers to Regulation ECER67 and is revised in combination with the actual needs of Chinese liquefied petroleum gas vehicles.
Technology Evolution Analysis
Compared with the old version, the main changes in the new version of the standard include:
- Increase in nominal working pressure:From $2.2\mathrm{MPa}$ to $3.0\mathrm{MPa}$
- Extension of operating temperature range:From $-40~^{\circ}C\sim60~^{\circ}C$ to $-40~^{\circ}C\sim65~^{\circ}C$
- Newly cited standards:Including GB/T528 and GB/T10567.2
- Detailed flow requirements:Divided into $\geqslant 20\mathrm{L}/\mathrm{min}$ and $\geqslant 20\mathrm{L}/\mathrm{min}$ according to the total mass of the vehicle. 30\mathrm{L}/\mathrm{min}$
Interpretation of core technical requirements
| Project | Specific requirements | Scope of application |
|---|---|---|
| Interface type and size | In accordance with the provisions of Appendix A, quick-plug design is preferred | All liquefied petroleum gas filling ports |
| Check valve requirements | At least 1 check valve with soft seat, opening pressure ≤ $0.2\mathrm{MPa}$ | Prevent backflow and pressure control |
| Pressure resistance | The hydrostatic strength test pressure is $6.75\mathrm{MPa}$, and the duration is ≥ $1\mathrm{min}$ | All gas filling port components |
Implementation suggestions and precautions
Common problems in actual application:
- Ensure the compatibility of the gas filling port with liquefied petroleum gas vehicles, refer to the requirements of GB19239
- Regularly check the sealing and airtightness of the one-way valve to avoid leakage risks
- Select an interface dust cover that meets the standards to prevent foreign matter from entering and affecting use
Summary:GB/T 18364—2017 provides comprehensive technical specifications for liquefied petroleum gas filling ports, emphasizing safety and reliability. During the implementation process, design, production and inspection should be carried out strictly in accordance with standard requirements to ensure compliance with the latest regulations and market demands.
