鑄鋼法蘭閘閥應(yīng)用
富林克Z41H鑄鋼法蘭閘閥是以鑄鋼為閥體材質(zhì)的閘閥,鑄鋼的優(yōu)點(diǎn)是有更大的設(shè)計(jì)靈活性和可變性、提高整體結(jié)構(gòu)強(qiáng)度和大范圍的重量變化。鑄鋼閘閥也是歷史悠久,使用廣泛的閥門結(jié)構(gòu)形式之一??蓮V泛用于自來水、污水、建筑、石油、化工、食品、醫(yī)藥、輕紡、電力、船舶、冶金、能源系統(tǒng)等體管線上作為截流裝置使用。

鑄鋼法蘭閘閥特點(diǎn)
1.閥體全部為精密鑄造閥體,材質(zhì)WCB達(dá)標(biāo),外觀精細(xì),無沙眼,每批鑄件都有爐號(hào)標(biāo)志,方便生產(chǎn)跟蹤 ,保材質(zhì)檢驗(yàn)
2.閥座cr系+堆焊507鉬,增加閥座耐磨性
3.閥蓋和閥桿接觸的地方做倒密封處理,防止外漏
4.閥桿采用旋風(fēng)銑加工,避免閥桿彎曲導(dǎo)致開關(guān)困難
5.每臺(tái)閥門出廠均按照國家標(biāo)準(zhǔn)做殼體,密封雙層壓力檢測
6.密封副配對(duì)*合理,閘板和閥座的密封面采用不同硬度的司太立(Stellite)鈷基硬質(zhì)合金堆焊而成,密封可靠、硬度高、耐磨、耐高溫、耐腐蝕、抗擦傷性能好、壽命長。
7.閥桿經(jīng)調(diào)質(zhì)及表面氮化處理,有良好的抗腐蝕性、抗擦傷性和耐磨性
8.采用楔式彈性閘板結(jié)構(gòu),中大口徑設(shè)置推力軸承,磨擦力小,并配有撞擊手動(dòng),啟閉輕松自如
