栓接閥蓋，提升式旋塞設計，它的密封性是通過閥片四周的 密封圈來實現的。*的燕尾槽保護和固定密封圈。雙向流動，安裝使用更方便。

Bolt bonnet OS&Y lifting一round plug, Its sealing is realized by the sealing rings around the valve disc. It has unique protection of swallow tailed sink and fixed sealing rings. Double direction.

⊙工作原理 Principle of opening and closing of the valve                                                                     

當閥門全開的狀態下，塞子的通道興閥體的通道對齊，能保證理想的zui低壓力降.當轉動手輪，塞片轉動9。度，當繼續轉動手輪，塞子將會下壓，使閥門向兩側張開，閥片將緊緊的壓在閥座上，使閥門關閉;當手輪向反方向轉動時，首先使塞子向上運動.使閥片于閥座脫離，繼續轉動手輪，使塞子帶動閥片90度zui后塞子的通道于閥體的通道對齊，使閥門處于全開的狀態。

When the valve is fully opened, the channel of plug is in alignment with the channel of valve body, which can ensure ideal and lowest desc rea seon pressure, When the hand wheel is turned, the plug will rotate toward the closing direction, and make the same time draft the rotation of valve seat will he Se- parated; if the hand wheel is turned inversely, first of all the plug will move upward, and the valve disc is turned by 90 degree driven by the plug, and finally the channel of plug will be in alignment with the channel of valve body, so that valve is be fully opened.
