The upper valve cover adopts metal bellows sealing structure. It can completely eliminate the possibility of the process medium leaking out from the movement gap of the pole. Due to the deformation of the bellows element itself and outstanding resistance to aging. It completely overcomes the weaknesses of packing aging and temperature difference sensitivity that usually exist in packing seal valves. Secondly, the use of bellows packing-double sealing structure has better safety and reliability.<\/p>\n
