ZHX呼吸閥
ZHX Breather Valve
ZHX呼吸閥閥體采用不銹鋼、優(yōu)質(zhì)鋁合金或鑄鐵制造，重量輕、耐腐蝕性能好。閥板、閥座間的密封面用工程塑料或鋁制作。閥閉合時(shí)，密封性能良好，達(dá)ANSI B16.104VI級(jí)標(biāo)準(zhǔn)。閥板、閥座、阻火層采用不銹鋼制造，阻火性能好。整體結(jié)構(gòu)按自力式原理設(shè)計(jì)，防爆性能優(yōu)越。
The body of ZHX breather valve is made of stainless steel,aluminum alloy or cast iron,characterized as light weight and strong corrosion resistance ability, the sealed face between the valve plate and valve seat of the ZHX breather valve is made of engineering plastic or aluminum,characterized as good seal performance reaching the ANSI B16.104 VI standards.The fire resistant layer of the valve plate and valve seat is made of stainless steel with the good performance of fire resistance.The structure of ZHX breather valve is designed according to the self-reliance principle with the super performance of explosion-proof.
產(chǎn)品功能用途（The produce function）
石油制品或其他化學(xué)溶劑如汽油、煤油、柴油、原油、苯、甲苯、乙醇或液氮、液氧等介質(zhì)，在生產(chǎn)過(guò)程或貯運(yùn)過(guò)程中，常在貯罐內(nèi)成品液上方覆蓋一層氮?dú)庾鞅Ｗo(hù)氣體，本產(chǎn)品與本廠氮封裝置或指揮器操作型自力式壓力調(diào)節(jié)閥配套使用（詳見(jiàn)產(chǎn)品使用說(shuō)明書），以防成品液或在制品接觸空氣而變質(zhì)。但某些場(chǎng)合也可單獨(dú)使用。
向貯罐注入液體或貯罐向外輸送液體時(shí)，或由于環(huán)境溫度改變等等原因都得影響貯罐內(nèi)氣相覆蓋層，壓力波動(dòng)。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(dòng)，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.
