進口氣體減壓閥-英國格林品牌
英國格林RRIMM進口氣體減壓閥各項性能指標*符合標準要求,能滿足生產(chǎn)需要和滿足技術(shù)性能要求,并可以保證后端設(shè)備的安全使用。是一種利用氣體介質(zhì)自身能量來調(diào)節(jié)與控制管路壓力的智能型閥門,通過啟閉件的開度來調(diào)節(jié)介質(zhì)的流量,將閥前管路較高的壓力減少至閥后管路所需的壓力,使閥后壓力保持在一定范圍內(nèi),在流量和進口壓力不斷變化的情況下,保持出口壓力在設(shè)定的范圍內(nèi)。在實際使用中,減壓閥同時實現(xiàn)了減壓功能和穩(wěn)壓功能,并且兩種功能缺一不可。廣泛應(yīng)用于氧氣、氫氣、氮氣、氬氣、氦氣、二氧化碳等氣體介質(zhì)。
進口氣體減壓閥特點:
1、閥體組件中的筒體采用不銹鋼棒料整體加工,解決了由于產(chǎn)品內(nèi)部缺陷引起的安全隱患,提高了閥門質(zhì)量。
2、活塞桿部件使用安全可靠的機械原理設(shè)計。閥芯運動為直線運動,這樣不會因為閥內(nèi)部件的松落而損壞旋轉(zhuǎn)部件。
3、閥門密封采用軟密封,密封圈為可拆換的氟橡膠密封圈,耐腐蝕性能好,密封效果好。閥芯與閥座為錐面接觸,與線接觸相比,接觸應(yīng)力和抗沖擊能力較好。
4、法蘭采用凹凸式結(jié)構(gòu),以防止密封面變形。

八、進口氣體減壓閥安裝說明
1、氣體減壓閥安裝必須嚴格按照閥體上的箭頭方向保持和流體流動方向*。如果氣體不清潔含有一些雜質(zhì),必須在減壓閥的上游進水口安裝過濾器(我們建議過濾精度不低于0.5mm)。
2、為了操作和維護方便,氣體減壓閥一般直立安裝在水平管道上。
3、為了防止氣體減壓閥閥后壓力超壓,應(yīng)在離閥出口不少于4M處加裝一個減壓閥。
4、減壓閥閥前和閥后必須裝截止閥,更換或者維修時開關(guān)氣體用
5、氣體如果有冷凝水的話,需要裝汽水分離器,防止冷凝水對減壓閥活塞或者膜片的損壞。
