Valve cover integrated floating ball valve

The utility model relates to a valve cover integrated floating ball valve which comprises a valve body with a first flow channel and a valve cover with a second flow channel, a cavity is arranged between the valve cover and the valve body, a ball body and an annular supporting valve seat are arranged in the cavity, the ball body abuts against the supporting valve seat, a sealing face is formed at the near end of the valve cover, and the sealing face is arranged around the second flow channel. The valve cover abuts against the outer surface of the ball body through the sealing face, and the sealing face is attached to the outer surface of the ball body. According to the ball valve, the path of fluid seeping from the cavity to the second flow channel is reduced, and then the sealing performance of the ball valve is improved. 本实用新型涉及一种阀盖一体式浮动球阀，包括带有第一流道的阀体和带有第二流道的阀盖，阀盖与阀体之间设有空腔，空腔内设有球体和环形的支撑阀座，球体与支撑阀座相抵，阀盖的近端成型有密封面，密封面环绕第二流道设置，阀盖通过密封面与球体的外表面相抵，密封面与球体的外表面贴合。其减少了流体从空腔渗流至第二流道的途径，进而提高了球阀的密封性。
