一、產(chǎn)品結構特點Structural characteristics of the product：

1.上裝式結構。對裝在管路上的閥門可直接在管路上檢查與維修，減少停車時間提高效益。
2.使用壽命長。中法蘭選用抗張、抗壓的金屬墊片增強抗溫，耐腐蝕性能有效延長使用壽命。
3.防止誤操作。開關帶鎖定裝置有效防止誤操作，確保閥門處于正確位置。

1 coat structure. Installed in the pipeline for the valve directly in the pipeline inspection and maintenance, decrease downtime and improve efficiency.
2 long life. Flanges used in the tensile, compressive resistance of the metal gasket enhanced temperature resistance, corrosion can effectively extend the service life.
3 to prevent misuse. Switch with an effective locking device to prevent misuse and ensure the valve is in the correct position.
