  呼吸阀是维护储罐气压平衡,减少介质挥发,呼吸阀充分利用储罐本身的承压能力来减少介质排放,其原理是利用正负压阀盘的重量来控制储罐的排气正压和吸气负压;当往罐外抽出介质,使罐内上部气体空间的压力下降,达到呼吸阀的操作负压时,罐外的大气将顶开呼吸阀的负压阀盘顶开,使外界气体进入罐内,使罐内的压力不再继续下降,让罐内与罐外的气压平衡,来保护储罐的安全装置。

  The Breathing Valve Is To Maintain The Pressure Balance Of The Storage Tank And Reduce The Volatilization Of Medium. The Breathing Valve Makes Full Use Of The Pressure Bearing Capacity Of The Storage Tank To Reduce The Medium Discharge. Its Principle Is To Control The Positive Exhaust Pressure And Negative Suction Pressure Of The Storage Tank By Using The Weight Of The Positive And Negative Pressure Valve Disc. When The Medium Is Pumped Out Of The Tank, The Pressure Of The Upper Gas Space Inside The Tank Will Drop And The Negative Pressure Of The Breathing Valve Will Be Reached The Negative Pressure Valve Disc Of The Top Opening Breathing Valve Is Opened To Make The External Gas Enter The Tank, So That The Pressure In The Tank Will Not Continue To Drop, And The Air Pressure Inside And Outside The Tank Can Be Balanced To Protect The Safety Device Of The Storage Tank.
