Experimental study on the side shrinkage phenomena of flat gate on the condition of small opening 平板閘門小開度時側(cè)收縮引起的水流現(xiàn)象試驗研究
Lift - horizontal gate was designed by the institute in the 1960 s and the book " lift - horizontal flat gate " was published . the gate operates in curved line when hoisting and is in horizontal state after entirely opening 本院愿以自身的科技優(yōu)勢服務(wù)社會,并愿與國內(nèi)外建立廣泛的業(yè)務(wù)聯(lián)系,加強多領(lǐng)域的技術(shù)交流與合作。
Using the system developed , we have set up the basic drawing - base of four different valves such as resilient seated gate valve , the wedge flat gate valve and the three - eccentricity butterfly valve etc . so these four type valves can be rapidly designed . it is shown that this system realizes the valve quickly modeling , consumedly increases the valve design efficiency , and has stronger extensibility 應(yīng)用已建立起的閥門三維參數(shù)化設(shè)計系統(tǒng)開發(fā)了“軟密封膠板閘閥” 、 “撐開式平板閘閥” 、 “三偏心蝶閥”等四種結(jié)構(gòu)的閥門基本圖形庫,可對這四種結(jié)構(gòu)的閥門進行快速序列化設(shè)計,大大提高了閥門設(shè)計生產(chǎn)效率,并具有較強的可擴充性。
