1、H72止回閥鋼鐵行業(yè)利潤增長1.2倍,但增幅明顯回落今年1-5月份鋼鐵行業(yè)利潤同比增長1.2倍,增幅比1-2月份的3.6倍明顯回落。一方面,是由于頭兩個(gè)月同期利潤基數(shù)較低,利潤高增長有短期效應(yīng);另一方面,是由于鋼鐵行業(yè)產(chǎn)銷增速回落,成本有所上升??傮w來看,二季度鋼材價(jià)格繼續(xù)呈穩(wěn)中上升態(tài)勢(shì),利潤仍保持較快增長,利潤增幅屬于正常回落。但我們也注意到,制約下半年鋼鐵行業(yè)利潤增長有以下幾個(gè)不利因素。一是鋼鐵行業(yè)的產(chǎn)銷增長對(duì)出口的依賴日益加劇。由凈進(jìn)口變?yōu)閮舫隹谝院?,前五個(gè)月粗鋼凈出口同比增量占了國內(nèi)粗鋼生產(chǎn)增量的54%,國際貿(mào)易摩擦對(duì)鋼鐵行業(yè)未來發(fā)展帶來許多不確定因素。二是今年4-6月國家四次出臺(tái)限制
2、鋼材出口的政策措施,包括降低出口退稅率、加征出口關(guān)稅、實(shí)施出口許可證管理等“組合拳”,力度大,頻率高,國內(nèi)市場(chǎng)反響強(qiáng)烈。首頁產(chǎn)品中心H71對(duì)夾升降式止回閥一、產(chǎn)品對(duì)夾升降式止回閥的詳細(xì)資料:產(chǎn)品型號(hào):H71產(chǎn)品名稱:對(duì)夾升降式止回閥產(chǎn)品特點(diǎn):二、流體力學(xué)性能:H71對(duì)夾升降式止回閥的體積流量與壓力降關(guān)系:水的當(dāng)量體積流量Vw與實(shí)際流體的 體積流量v按下式換算:式中:Vw一水的當(dāng)量體積流量ls;P一流體密度,kgm3v一實(shí)際流體的體積流量,Is;v一實(shí)際流體的體積流量,Is。 三、流體力學(xué)性能:H71對(duì)夾雙瓣旋啟式止回閥的流體阻力系數(shù)、流量系數(shù)及開啟壓力:公稱通徑閥門全開啟時(shí)的流體阻力系數(shù)常溫下
