QC/T 674-2007 (English Version) PDF

Scope: This standard specifies the product type and basic parameters, requirements, test methods, inspection rules and markings, packaging, transportation and storage of compressed natural gas solenoid valves for automobiles (as defined in GB/T 17895). This standard is applicable to working environment conditions where the working pressure is not greater than 2OMPa (the pressures mentioned in this standard refer to gauge pressure), the ambient temperature is -40 ℃ ~ +120 ℃, and the relative humidity is 5% ~ 100%, in order to comply with GB 18047 The required compressed natural gas for automobiles is used as the working medium, and the solenoid valve realizes the opening and closing control function in the compressed natural gas supply system of gas automobiles.
