QB2雙口排氣閥誕生于70年代，體形大,重量重，北京微量排氣閥，北京微量排氣閥，排氣量小，該排氣閥在80年代末**為理想產(chǎn)品，問世以來一直還續(xù)用。排氣閥是管道必配設(shè)備，安裝在管道highest點(diǎn)或閉氣地方，來排除管內(nèi)氣體，來疏通管道，使管道運(yùn)轉(zhuǎn)正常，如停電，北京微量排氣閥，停泵管內(nèi)會(huì)出現(xiàn)負(fù)壓力會(huì)引起管道振動(dòng)或破裂，該排氣閥隨時(shí)吸氣，確保管路安全。

SCAR污水復(fù)合式排氣閥用于管路上的highest點(diǎn)或有閉氣的地方，排除管內(nèi)的氣體來疏通管道，達(dá)到正常工作，如不裝排氣閥，管內(nèi)流動(dòng)的液體產(chǎn)生動(dòng)熱引起氣體，形成短路，使管道出水容量達(dá)不到要求，其次，管道運(yùn)轉(zhuǎn)時(shí)出現(xiàn)停電、停泵管道會(huì)出現(xiàn)負(fù)壓力，而會(huì)引起管道振動(dòng)或破裂，排（吸）氣閥就迅速把空氣吸入管內(nèi)，防止管道振動(dòng)或破裂。本閥裝設(shè)于泵埔出口處或送配水管線中，用以大量排除管道中的集結(jié)之空氣，以增進(jìn)水管及抽水機(jī)使用效率，且與管內(nèi)一旦出現(xiàn)負(fù)壓時(shí)，此閥能迅速吸入空氣，以保管線因負(fù)壓所產(chǎn)生損壞。當(dāng)管內(nèi)開始注水時(shí)，塞頭停留在開啟位置，進(jìn)行大量排氣，當(dāng)空氣排完時(shí)，閥內(nèi)積水浮球被浮起，傳動(dòng)塞頭至關(guān)閉位置，停止大量排氣；當(dāng)管內(nèi)水正常輸送時(shí)，如有少量空氣聚集在閥內(nèi)到相當(dāng)程度，閥內(nèi)水位下降，浮球隨之下降，此時(shí)空氣則由小孔排出。當(dāng)抽水機(jī)停止，管內(nèi)水流空時(shí)，或遇管內(nèi)產(chǎn)生負(fù)壓時(shí)，此時(shí)塞頭開啟，吸入空氣確保管線安全。</p><div

QB1單口排氣閥主要由閥體、閥門、上蓋、閥桿、浮球、排氣嘴等組成。當(dāng)需要排出管道內(nèi)的氣體時(shí)，管道內(nèi)的空氣在水的壓強(qiáng)作用下進(jìn)入體腔內(nèi)，并從排氣嘴排出，隨之管道內(nèi)的水充滿體腔內(nèi)，使浮球在水的浮力作用下，向上移動(dòng)將排氣嘴堵塞，達(dá)到自行密封，管道在正常行中，水中的空氣在壓強(qiáng)的作用下，不斷排入排氣閥的體腔上部，迫使浮球下降，離開原來密封位置，這時(shí)空氣又從排氣嘴排出，隨之，浮球又恢復(fù)到原來位置自密封，因此，排氣閥在正常工作中閥門始終是開著的，浮球不斷重復(fù)上述動(dòng)作，空氣不斷排出。當(dāng)需要檢修或清掃體腔時(shí)，應(yīng)將閥門關(guān)閉。
