進(jìn)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(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。一般它被用在常壓或低壓貯罐上。焦炭塔的呼吸閥有兩個(gè)用處:一、放水時(shí),吸氣,以利塔內(nèi)存水順利放出;二、呼氣,蒸汽趕空氣時(shí),用以放凈空氣,脫水放汽時(shí),用以檢查塔內(nèi)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(chǔ)罐上的主要安全設(shè)備,是起蒸發(fā)損耗與保護(hù)儲(chǔ)罐在受超壓或 真空時(shí)免遭破壞的作用。此閥通常與阻火器配套使用。當(dāng)外界大氣壓力大于罐內(nèi)壓力時(shí) 就會(huì)往罐內(nèi)補(bǔ)氣 從而達(dá)到內(nèi)外壓力的平衡。呼吸閥是固定在儲(chǔ)罐頂上的通風(fēng)裝置,以保證罐內(nèi)壓力的正常狀態(tài),防止罐內(nèi)超壓或真空使儲(chǔ)罐遭受損壞,也可減少罐內(nèi)液體揮發(fā)損失。根據(jù)中國《石油化工設(shè)計(jì)防火規(guī)范》(GB50160-92)的規(guī)定:“甲、乙類液體的固定頂罐,應(yīng)設(shè)阻火器和呼吸閥”,結(jié)構(gòu)緊湊、重量輕、通風(fēng)量大、泄露小等優(yōu)點(diǎn)。產(chǎn)品有單呼閥、單吸閥、呼吸閥,各種結(jié)構(gòu)型式均可與阻火器組合構(gòu)造,也可配制所需的接管。
