產(chǎn)品詳情
不銹鋼螺紋旋啟式止回閥的功能是用來防止管路中的介質(zhì)倒流。止回閥屬于自動閥類，啟閉件靠流動介質(zhì)的力量自行開啟或關(guān)閉。止回閥只用于介質(zhì)單向流動的管路上，阻止介質(zhì)回流，以防發(fā)生事故。
適用介質(zhì)為：水、油品、蒸汽、酸性介質(zhì)等。不銹鋼螺紋旋啟式止回閥標(biāo)準(zhǔn)：設(shè)計與制造結(jié)構(gòu)長度壓力-溫度等級連接法蘭試驗與檢驗gb12236gb12221gb9131jb/t74hg20604jb/t74-94gb9113hg20592-20635jb/t9092-1999gb13927不銹鋼螺紋旋啟式止回閥壓力試驗：稱壓力pn(mpa)試驗壓力(mpa)適用溫度(℃)適用介質(zhì)強(qiáng)度試驗密封試驗wcbcr5mo1cr18ni12mo2ti1cr18ni9ti1.62.41.8≤425≤550≤220≤200水、油品、蒸汽、酸性介質(zhì)2.53.82.84.06.04.46.49.67.110.015.011.0-16.024.017.625.037.527.5主要零件材料及性能：零件名稱材料編號閥體wcbzgcr5mozg1cr18ni9tizg1cr18ni12mo2ti閥蓋wcbzgcr5mozg1cr18ni9tizg1cr18ni12mo2ti閥瓣wcbzgcr5mozg1cr18ni9tizg1cr18ni12mo2ti搖桿wcbzgcr5mozg1cr18ni9tizg1cr18ni12mo2ti閥座251cr18ni9ti1cr18ni9ti1cr18ni12mo2ti銷軸1cr17ni21cr18ni9ti1cr18ni12mo2ti密封環(huán)、墊片包覆墊1cr18ni9ti1cr18ni12mo2ti主要技術(shù)尺寸:公稱壓力pn(mpa)公稱直徑dn(mm)主要外形尺寸及連接尺寸(mm)重量(kg)ldd1d2b-fz-dd3h1.625160115856516-24--1414013014321801351007816-24--1815014016402001451108516-24--18160150185023016012510016-24--18185160226529018014512018-34--18215177268031019516013520-38-1823518733100354021518015520-38-182552023912540024521018522-38-182852275715048028024021024--38-233302638020055033529526526-312-233852939525065040535532030-312-2545533017530075046041037530-412-2551538226035085052047043534--316-2554543036040095058052548536-416-30600480496500115070565060844--420-34730560588
