Beschreibung
Zusammenfassung:	The utility model belongs to the technical field of the valve is made. The plug valve includes: valve body and valve ball, the valve ball is embedded in hollow valve body, characterized in that: the skew valve body axial lead predetermined distance of the valve ball centre of sphere of plug valve. Predetermined distance through the skew valve body axial lead of the valve ball centre of sphere is transformed into partial sealing load and opens moment, and the messenger is difficult for opening under high-pressure state or the plug valve of not opening can easily be opened.
