產品功能用途（The produce function）

石油制品或其他化學溶劑如汽油、煤油、柴油、原油、苯、甲苯、乙醇或液氮、液氧等介質，在生產過程或貯運過程中，常在貯罐內成品液上方覆蓋一層氮氣作保護氣體，本產品與本廠氮封裝置或指揮器操作型自力式壓力調節閥配套使用（詳見產品使用說明書），以防成品液或在制品接觸空氣而變質。但某些場合也可單獨使用。

向貯罐注入液體或貯罐向外輸送液體時，或由于環境溫度改變等等原因都得影響貯罐內氣相覆蓋層，壓力波動。安裝配置了該呼吸閥后，能迅速排除由上述原因引起的壓力波動，維持貯罐壓力恒定。

In the transportation of petroleum products or other chemical solvents,such as gasoline,kerosene,diesel fuel,crude oil,benzene,toluene,ethanol or liquid nitrogen,liquid oxygen and other media,the nitrogen always is covered on the top of the tank for the protection.the breather valve can be together used with the nitrogen sealed unit or the commａnd device operation type self-operated pressure regulator(see the product specifications)for the prevention of metamorphic contacting air,ａnd the above mentioned products can be applied separately.

Above mentioned products can be applied separately.

Equipment of the breather valve,it can timely remove the pressure fluctuation caused by the reason of injecting liquid into or taking liquid from the tank or the changes in ambient temperature.
