根據(jù)國家標準<石油化工企業(yè)設計防火規(guī)范>(GB50160-90)之規(guī)定,"甲,乙類液體的固定頂罐,應用阻火器和呼吸閥".可見呼吸閥,阻火器是儲罐不可缺少的安全設施.它不僅能維持儲罐氣壓平衡,確保儲罐在超壓或真空時兔遭破壞,且能減少罐內(nèi)介質(zhì)的揮發(fā)和損耗.我公司生產(chǎn)的呼吸閥,具有結(jié)構(gòu)緊湊,通氣量大,泄漏量小,密封性能好等特點.最近又開發(fā)了具有國際先進水準的防爆阻火器呼吸閥(HXF-IZ型),阻火器位于呼吸閥吸入口處,徹底杜絕火源進入呼吸閥殼體內(nèi).具有體積小,重量輕,檢修,清洗,更換方便等優(yōu)點.歡迎新老用戶關(guān)顧<精凱>更多產(chǎn)品詳情請登陸:http://或電話咨詢:022 60365199/24689079Flarne Arrsetor and breather valve should be equipped on the fop of tank for type A and B liquid according to GB50160-92,"Fire prevention code of petrol chermical enterprise design".Breather valve and flame arrestor are indispensable safety devices.They can not only remain tank internal norrnal pressure,but also prevent over pressure or vacuum in tank and reduce liquid volatilization loss in tank
Our breather valve have some good features,such as wo have recently produced a new flame breather valve HXF-IZ,which the flarne arrestor is installed the suction end of breather valve,avoiding flame into the body of breather valve,It is charactenized by better inspection,clear up and replacement
