| Abstract: | The working principle,structure characteristics and performance characteristics of shale gas drilling wellhead flat valve was introduced. Based on API 6A design criteria and design formulas,the flat valve is designed with a single valve plate of floating seat structure while using hydraulic pressure as the valve switch driving force. To get good pressure resistance,wear resistance and sealing,cemented carbide powder is used for thermal spraying on the valve plate and seat seal. |
