?產(chǎn)品概述
軸流式止回閥又稱貫流式止回閥是我公司吸收技術(shù)集合實(shí)際工況自行研發(fā)設(shè)計(jì)的一種高性能止回閥。本閥門閥瓣重量輕,動(dòng)作靈敏,行程較短, 壓力損失在可允許范圍內(nèi)、關(guān)閉時(shí)無沖擊、無噪聲、不受安裝位置限制等特點(diǎn)。廣泛運(yùn)用在管道系統(tǒng)中防止液體倒流危害,保護(hù)機(jī)械設(shè)備,既具備一般止回閥的 功能特性,又減輕水錘危害、降低噪聲、減小壓降和快速反應(yīng)等。
?產(chǎn)品特點(diǎn)
1、閥體整體鑄造或鍛造,閥門沒有外部泄漏點(diǎn)的現(xiàn)象,閥門由閥體、導(dǎo)流體、軸向運(yùn)動(dòng)閥瓣和彈簧部件組成;
2、閥體,閥瓣,尾椎設(shè)計(jì)成流線型通道,流體性能,限度減少流阻和壓力;
3、運(yùn)用高性能彈簧材料,耐腐性能,抗氧化機(jī)械性能,確保彈簧長期工作情況下,運(yùn)行狀態(tài);
4、式運(yùn)行,從而消除閥門管道中的噪音和水錘確保設(shè)備和管道安全;
5、開啟與關(guān)閉反應(yīng)迅速,可靠的預(yù)壓彈簧使閥瓣對流體壓力變化快速反應(yīng);
6、結(jié)構(gòu)緊湊,方便安裝,垂直,水平安裝都可;
7、閥門采用合金鋼堆焊密封面,耐磨,耐腐,壽命長;
8、閥門的壓力范圍比較廣。
