進口呼吸閥概述
呼吸閥類似于單向止逆閥,它只能向外呼氣,不能向內吸氣,當系統(tǒng)內壓力升高時,氣體便經過呼吸閥向外放空,保證系統(tǒng)的壓力恒定。一般它被用在常壓或低壓貯罐上。焦炭塔的呼吸閥有兩個用處:一、放水時,吸氣,以利塔內存水順利放出;二、呼氣,蒸汽趕空氣時,用以放凈空氣,脫水放汽時,用以檢查塔內是否為正壓。呼吸閥是用于安裝原油、汽油、煤油、輕柴油、芳烴等固定頂式儲罐上的主要安全設備,是起蒸發(fā)損耗與保護儲罐在受超壓或 真空時免遭破壞的作用。此閥通常與阻火器配套使用。當外界大氣壓力大于罐內壓力時 就會往罐內補氣 從而達到內外壓力的平衡。呼吸閥是固定在儲罐頂上的通風裝置,以保證罐內壓力的正常狀態(tài),防止罐內超壓或真空使儲罐遭受損壞,也可減少罐內液體揮發(fā)損失。根據中國《石油化工設計防火規(guī)范》(GB50160-92)的規(guī)定:“甲、乙類液體的固定頂罐,應設阻火器和呼吸閥”,結構緊湊、重量輕、通風量大、泄露小等優(yōu)點。產品有單呼閥、單吸閥、呼吸閥,各種結構型式均可與阻火器組合構造,也可配制所需的接管。
