GB1796-1996
Foreword
This standard is revised based on the development status of tire valves in my country in recent years and the implementation of GB1796-88 and user usage.
The structural type of the valve refers to foreign standard materials such as TRA Yearbook (1994), JATMA Yearbook (1994) and ETRTO Standard Guide (1993). The cited GB9764-88 "Tire Valve Core Cavity" and GB9765-88 "Tire Valve Thread" are not equivalent to ISO7442:1982 "Tire Valve No. 1 Core Cavity" and ISO4570-1:1977 "Tire Valve" respectively. Threads Part 1", ISO4570-2:1979 "Tire valve threads Part 2". According to the provisions of GB/T3900-91 "Tire Valve Series", this standard has revised the product classification and marking of valves; added and deleted valve specifications, revised and supplemented the inspection rules based on the previous version, and added the tire Comparison table of domestic and foreign valve models. This standard is based on the production and use of valves in my country. The valve body only makes specific provisions for the metal part, and its rubber seat part should comply with the regulations of GB12835-91 "Plastic Seat Valve". This standard will replace GB1796-88 from the effective date. Appendix A of this standard is a reminder appendix.
This standard is proposed by the Ministry of Chemical Industry of the People's Republic of China. This standard is under the jurisdiction of the National Tire and Rim Standardization Technical Committee. This standard is drafted by Shandong Valve Factory, and Shenyang Rubber Machinery Factory participates in the drafting. The main drafters of this standard: Li Feng, Cui Jie, Liu Qizhong. This standard was first published in November 1979 and revised for the first time in May 1988. This standard is entrusted to the Valve Standardization Sub-Technical Committee of the National Tire and Rim Standardization Technical Committee to be responsible for interpretation. 133
