Bridgestone's first tireless tires produced in China
With the Bridgestone Group's most cutting-edge technology, the first Chinese-made gas-filled tires with safety, environmental friendliness, and convenience were formally rolled out at the Bridgestone Wuxi plant. At the same time, China's No. 1 run-flat tires will also be included in the history of the plant as the 20 million tire products since the founding of the Bridgestone Wuxi factory. Bridgestone Group CEO Arakawa Yuki and Bridgestone (China) Investment Co., Ltd. Chairman Daejeon Kang attended the off-line ceremony. Chairman Daejeon Kang expressed that China is one of Bridgestone’s most important development markets. In the 12 years of localization, under the guidance of the corporate philosophy of “contributing to society with the highest qualityâ€, China has been adhering to the “best productâ€. The business principle of “to China†continues to promote the Group’s advanced product production line to the Chinese factory, providing Chinese consumers with more convenience and choice. Globe valve, also known as cut-off valve, is a mandatory sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from under the valve disc, the resistance that the operating force needs to overcome is the friction force between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the valve stem The diameter of the valve should be large, otherwise the failure of the top of the valve stem will occur. According to the connection method, it is divided into three types: flange connection, thread connection and welding connection. After the appearance of the self-sealing valve, the medium flow direction of the globe valve is changed from the top of the valve disc into the valve cavity. At this time, under the action of the medium pressure, the force to close the valve is small, but the force to open the valve is large, and the diameter of the valve stem can be adjusted accordingly. decrease. At the same time, under the action of the medium, this form of valve is also tighter. my country's valve "Three Chemicals" once stipulated that the flow direction of the globe valve should be from top to bottom. When the globe valve is opened, the opening height of the valve disc is 25% to 30% of the nominal diameter. The flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the fully open position of the globe valve should be determined by the stroke of the valve disc.
