進口呼吸閥、單呼閥(RBT品牌)
產品介紹:
進口呼吸閥是利用油罐本身的承壓能力來減少油蒸氣排放,其原理是利用閥盤的重量來控制油罐的呼氣正壓和吸氣負壓。當罐內氣體的壓力在機械呼吸閥的控制壓力范圍之內時,呼吸閥不動作,保持油罐的密閉性;當罐內氣體空間的壓力升高,達到呼吸閥的控制正壓時,壓力閥被頂開,氣體從罐內逸出,使罐內壓力不在繼續增高;當罐內氣體空間的壓力下降,達到呼吸閥的控制負壓時,罐外的大氣將頂開真空閥而進入罐內,使罐內的壓力不在繼續下降。
Import breathing valve is the ability to use the tank pressure to reduce its oil vapor emissions, the principle is to use the weight of the valve plate to control the tank pressure and inspiratory negative pressure of breath. When the tank pressure of the gas control valve in the mechanical ventilator pressure within the breathing valve does not move and maintain airtight tank; air space when the tank pressure increases, breathing valve to control pressure, the pressure top of the valve is open, the gas escaping from the tank so that tank pressure does not continue to increase; air space when the tank pressure drops, breathing valve to control the negative pressure, the tank will be the top open air outside the vacuum valve and into the tank , so that the pressure tank is not continued to decline.
