产品功能用途（The produce function）

石油制品或其他化学溶剂如汽油、煤油、柴油、原油、苯、甲苯、乙醇或液氮、液氧等介质，在生产过程或贮运过程中，常在贮罐内成品液上方覆盖一层氮气作保护气体，本产品与本厂氮封装置或指挥器操作型自力式压力调节阀配套使用（详见产品使用说明书），以防成品液或在制品接触空气而变质。但某些场合也可单独使用。

向贮罐注入液体或贮罐向外输送液体时，或由于环境温度改变等等原因都得影响贮罐内气相覆盖层，压力波动。安装配置了该呼吸阀后，能迅速排除由上述原因引起的压力波动，维持贮罐压力恒定。

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.
