產(chǎn)品結(jié)構(gòu)特點(diǎn) Construction features
1、抗硫化應(yīng)力裂化:閥門(mén)接觸介質(zhì)的材料都是按美國(guó)腐蝕工程師協(xié)會(huì)NACE01-75的標(biāo)準(zhǔn)進(jìn)行選擇,且按標(biāo)準(zhǔn)進(jìn)行表面鍍鎳,能滿(mǎn)足硫化環(huán)境工況的要求。 2、用聚合物或金屬作密封材料,在高溫、高壓工況具有優(yōu)良的密封性能。 3、設(shè)置填料箱,防止閥門(mén)內(nèi)腔壓力異常升高而使閥桿飛出,增置倒密封結(jié)構(gòu),能確保填料可靠密封。 4、廣泛適用于化工、煉油、油氣、天然氣、鋼鐵等介質(zhì)管路。 1. Resistance to sulfide stress cracking: valve contact medium materials are according to the American association of corrosion engineers NACE01-75 standards for choice, and according to the standard to nickel plating on the surface, can satisfy the requirement of curing environment conditions. 2. Sealing material with polymer or metal, excellent sealing performance in high temperature and high pressure condition. 3. Set the stuffing box to prevent the pressure of the inner cavity of the valve to rise and make the stem fly out, adding the backsealing structure to ensure the packing is reliable. 4. Widely applicable to chemical, oil, gas, natural gas, steel and other media pipelines.
