聚丙烯濾芯取代傳統(tǒng)濾芯,是新一代過濾元器件濾芯為聚丙烯粒子經(jīng)過熔融、噴射成微細(xì)的纖維并貼緊繞制成潔白管狀濾芯,無毒,過濾時纖維不會脫落,又保持良限的透氣性。
包裝:先用減震帶包裝,外用泡面包裝,*后用紙箱封裝,膠帶纏好,封緊,外套化纖袋封裝;路途遙遠(yuǎn)的外面用木箱封裝,我們確保產(chǎn)品在運(yùn)輸過程中的安全性。
呼吸閥是維護(hù)儲罐氣壓平衡,減少介質(zhì)揮發(fā)的安全節(jié)能產(chǎn)品,呼吸閥充分利用儲罐本身的承壓能力來減少介質(zhì)排放,其原理是利用正負(fù)壓閥盤的重量來控制儲罐的排氣正壓和吸氣負(fù)壓。當(dāng)罐內(nèi)介質(zhì)的壓力在呼吸閥的控制操作壓力范圍之內(nèi)時,呼吸閥不工作,保持油罐的密閉性;當(dāng)往罐內(nèi)補(bǔ)充介質(zhì),使罐內(nèi)上部氣體空間的壓力升高,達(dá)到呼吸閥的操作正壓時,壓力閥被頂開,氣體從呼吸閥呼出口逸出,使罐內(nèi)壓力不在繼續(xù)增高;當(dāng)往罐外抽出介質(zhì),使罐內(nèi)上部氣體空間的壓力下降,達(dá)到呼吸閥的操作負(fù)壓時,罐外的大氣將頂開呼吸閥的負(fù)壓閥盤頂開,使外界氣體進(jìn)入罐內(nèi),使罐內(nèi)的壓力不再繼續(xù)下降,讓罐內(nèi)與罐外的氣壓平衡,來保護(hù)儲罐的安全裝置。

呼吸閥分類:
按選用材質(zhì)可分為:不銹鋼(304、304L、316、316L)呼吸閥、鋁合金呼吸閥、塑料(PVC、PP)呼吸閥;
按工作原理可分為兩種:
*種是達(dá)到一定壓力時,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,氣體便經(jīng)過呼吸閥向外放空,保證系統(tǒng)的壓力恒定。對于存放有毒物質(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。
英文介紹:
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:
不銹鋼呼吸閥,衛(wèi)生級呼吸閥,不銹鋼呼吸閥價格,衛(wèi)生級呼吸閥原理,溫州呼吸閥生產(chǎn)廠家;
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)。
