Principle of opening and closing of the valves
  ~when the valves is fully opened,the channel of plug is in alignment with the channel of valves body,which can ensure ideal and lowest decrease on pressure.When the hand wheel is turned,the plug will rotate toward the closing direction,and make the same time draft the rotation of valves seat and close the valves.When the hand wheel is turned inversely,first of all the plug will move ipward,and the valves disc and valves seat will be separated;if the hand wheel is turned further on;till the valves disc is turned by 90 degree driven by the plug,and finally the channel of plug will be in alignment with the channel of valves body,so that the valves is be fully opened.
