呼吸阀是维护储罐气压平衡,减少介质挥发的安全节能产品,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。当罐内介质的压力在呼吸阀的控制操作压力范围之内时,呼吸阀不工作,保持油罐的密闭性;当往罐内补充介质,使罐内上部气体空间的压力升高,达到呼吸阀的操作正压时,压力阀被顶开,气体从呼吸阀呼出口逸出,使罐内压力不在继续增高;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。

呼吸阀分类:
按选用材质可分为:不锈钢(304、304L、316、316L)呼吸阀、铝合金呼吸阀、塑料(PVC、PP)呼吸阀;
按工作原理可分为两种:
*种是达到一定压力时,进行呼或吸;另一种是设计成纯粹只呼不吸,可以理解为用两个适当压力的单向阀代替。
第二种呼吸阀类似于单向止逆阀,它只能向外呼气,不能向内吸气,当系统内压力升高时,气体便经过呼吸阀向外放空,保证系统的压力恒定。对于存放有毒物质的贮罐,是没有的呼吸阀的,或者加活性碳过滤器等处理装置的。
英文介绍:
Breathing valve to maintain the the tank pressure balance, safety and energy saving products to reduce the evaporation of the medium, to take full advantage of the pressure of the tank itself breathing valve to reduce the medium emissions, its principle is to use the weight of the positive and negative pressure valve disk to control the tank platoonair positive pressure and negative pressure of suction. When the tank pressure of the medium in the breathing valve control operation of the pressure range within the breathing valve is not working, to maintain the tightness of the oil tank; medium supplemented to the tank, the tank upper portion of the gas space increased pressure to achieve breathing operation of the valve when the positive pressure, the pressure valve is open the top and the call outlet escape of gas from the breathing valve, so that the pressure in the tank is not continue to increase; decline in pressure when the extraction medium, so that an upper gas space of the tank to the outside of the tank, to achieve the breathing valve operating negative pressure outside the atmosphere in the tank top open breathing valve negative pressure valve disc to open the top, so that the outside air into the tank, so that the pressure inside the tank is no longer continued to decline, so that the outside of the tank and the tank pressure balance to protect the safety device of the storage tank.
Breathing valve:
不锈钢呼吸阀,卫生级呼吸阀,不锈钢呼吸阀价格,卫生级呼吸阀原理,温州呼吸阀生产厂家;
Selection of materials can be divided into: stainless steel (304,304 L, 316,316 L) breathing valve aluminum alloy breathing valve, plastic (PVC, PP) breathing valve;
Can be divided into two types according to the principle:
The first one is when the pressure reaches a certain call or absorption; another is designed purely respiratory suction, can be understood as a one-way valve instead of the two appropriate pressure.
Second breathing valve similar to the one-way check valve, it can only be out of breath, not inward suction, when increased pressure within the system, the gas will be out after the breathing valve venting, the constant pressure of the guarantee system. Tank for storage of toxic substances is not breathing valve, plus activated carbon filter processing device.
Breathing valve is generally used in atmospheric or low pressure tank that only atmospheric pressure and low-pressure storage tanks have tank breathing emissions (often a vapor recovery system on the low pressure tank), the high-pressure tank emissions, no breathing losses and work losses.
The emissions into fixed roof tank breathing loss (small breathing emissions) and loss (large breathing emissions).
呼吸阀一般用在常压或低压贮罐上,即只有常压和低压贮罐才有罐呼吸排放(在低压罐上常有蒸汽回收系统),高压贮罐没有排放量,无呼吸损失和工作损失。
固定顶罐的主要排放量分为呼吸损失(小呼吸排放)和工作损失(大呼吸排放)。
