ZFQ-1 DN50阻火呼吸閥 304不銹鋼防爆阻火透氣 詳細(xì)參數(shù) 產(chǎn)品尺寸規(guī)格參考:呼吸閥高度200MM 寬230MM,法蘭直徑165MM。法蘭厚度17MM,孔距125MM,內(nèi)孔直徑50MM,孔徑18MM規(guī)格:DN50介質(zhì)溫度:60(℃)工作壓差:無材質(zhì):304不銹鋼品牌:
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,食品級(jí)呼吸閥,不銹鋼儲(chǔ)罐呼吸閥I無菌呼吸閥 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.
呼吸閥分為兩種: *種是達(dá)到一定壓力時(shí),進(jìn)行呼或吸;另一種是設(shè)計(jì)成純粹只呼不吸,可以理解為用兩個(gè)適當(dāng)壓力的單向閥代替。 第二種呼吸閥類似于單向止逆閥,它只能向外呼氣,不能向內(nèi)吸氣,當(dāng)系統(tǒng)內(nèi)壓力升高時(shí),氣體便經(jīng)過呼吸閥向外放空,保證系統(tǒng)的壓力恒定。對(duì)于存放有毒物質(zhì)的貯罐,是沒有的呼吸閥的,或者加活性碳過濾器等處理裝置的。 呼吸閥一般用在常壓或低壓貯罐上,即只有常壓和低壓貯罐才有罐呼吸排放(在低壓罐上常有蒸汽回收系統(tǒng)),高壓貯罐沒有排放量,無呼吸損失和工作損失。 固定頂罐的主要排放量分為呼吸損失(小呼吸排放)和工作損失(大呼吸排放)。 |
