閥(fa)(fa)門(men)是大(da)(da)型(xing)成套裝置中的(de)(de)重(zhong)(zhong)要(yao)組(zu)成部分,主(zhu)要(yao)用(yong)(yong)于工(gong)(gong)藝管道介質(物(wu)料(liao)(liao)、水、蒸(zheng)汽(qi)、空(kong)氣和油品(pin)等)的(de)(de)切斷、節流、調(diao)壓和改(gai)變流向等。閥(fa)(fa)門(men)質量的(de)(de)優(you)劣直(zhi)接(jie)影響這些裝置能(neng)否正常生產(chan)、安全(quan)運(yun)轉(zhuan),并起著至關重(zhong)(zhong)要(yao)的(de)(de)作用(yong)(yong)。閥(fa)(fa)門(men)的(de)(de)品(pin)種規格多、用(yong)(yong)途廣、用(yong)(yong)量大(da)(da)。我國的(de)(de)閥(fa)(fa)門(men)制(zhi)造(zao)普(pu)遍以金(jin)屬(shu)材料(liao)(liao)為(wei)主(zhu),雖然金(jin)屬(shu)閥(fa)(fa)門(men)經過結(jie)構及材料(liao)(liao)的(de)(de)改(gai)進,但受(shou)金(jin)屬(shu)材料(liao)(liao)屬(shu)性的(de)(de)限(xian)制(zhi),在化工(gong)(gong),煤炭(tan),石(shi)油等惡(e)劣環境下金(jin)屬(shu)閥(fa)(fa)門(men)已不(bu)能(neng)適應高(gao)磨(mo)損、強腐蝕(shi)等惡(e)劣工(gong)(gong)況的(de)(de)需求,主(zhu)要(yao)體現在使用(yong)(yong)壽命短,泄露嚴重(zhong)(zhong),大(da)(da)大(da)(da)影響了系(xi)統運(yun)行的(de)(de)穩(wen)定(ding)性。
二十一世紀以來(lai),先進(jin)的(de)陶(tao)(tao)(tao)瓷(ci)(ci)(ci)材(cai)料(liao)(liao)作為一種(zhong)新的(de)材(cai)料(liao)(liao)走進(jin)了科(ke)技工作者(zhe)的(de)視野(ye),將陶(tao)(tao)(tao)瓷(ci)(ci)(ci)材(cai)料(liao)(liao)運用到工業(ye)閥(fa)門(men)之(zhi)中是一項大膽和(he)有益的(de)創(chuang)新。上鍋閥(fa)門(men)則是國(guo)內較早從事陶(tao)(tao)(tao)瓷(ci)(ci)(ci)閥(fa)門(men)制(zhi)造(zao)的(de)企業(ye),多(duo)(duo)年(nian)來(lai)研制(zhi)出陶(tao)(tao)(tao)瓷(ci)(ci)(ci)球閥(fa)、陶(tao)(tao)(tao)瓷(ci)(ci)(ci)刀(dao)閥(fa)、陶(tao)(tao)(tao)瓷(ci)(ci)(ci)排渣閥(fa)、陶(tao)(tao)(tao)瓷(ci)(ci)(ci)止回閥(fa)、陶(tao)(tao)(tao)瓷(ci)(ci)(ci)進(jin)料(liao)(liao)閥(fa)、陶(tao)(tao)(tao)瓷(ci)(ci)(ci)蝶閥(fa)等十多(duo)(duo)個品種(zhong),為解決特殊工況的(de)閥(fa)門(men)需求作出了積(ji)極的(de)探索。
陶(tao)瓷(ci)(ci)材料變(bian)形(xing)量(liang)很(hen)小(xiao)(xiao),比金屬具有高(gao)得(de)(de)多的結(jie)合強(qiang)(qiang)度(du)(du),一般情況下組成陶(tao)瓷(ci)(ci)材料的晶(jing)體離(li)子半徑小(xiao)(xiao),而且離(li)子電價高(gao),配位數(shu)大(da),這些性質決定了(le)陶(tao)瓷(ci)(ci)材料抗拉度(du)(du)強(qiang)(qiang),彈性模(mo)量(liang)、硬度(du)(du)等都非常高(gao)。然(ran)而陶(tao)瓷(ci)(ci)本身的“脆”及(ji)難加(jia)工(gong)限制了(le)它的應(ying)用(yong)范(fan)圍(wei),近十幾年(nian)來,由(you)于馬氏體相變(bian)增韌技術、復合材料技術及(ji)納(na)米陶(tao)瓷(ci)(ci)概念(nian)的發展及(ji)進步(bu),已使陶(tao)瓷(ci)(ci)的“脆性”得(de)(de)到(dao)了(le)大(da)大(da)改(gai)進,其(qi)韌性和(he)強(qiang)(qiang)度(du)(du)得(de)(de)到(dao)了(le)極(ji)大(da)的提高(gao),應(ying)用(yong)范(fan)圍(wei)不(bu)斷(duan)(duan)擴展。新(xin)型陶(tao)瓷(ci)(ci)材料不(bu)斷(duan)(duan)被應(ying)用(yong)在石(shi)油(you)、化工(gong)、機械等領域(yu),利用(yong)陶(tao)瓷(ci)(ci)的耐(nai)磨性、耐(nai)腐性制造(zao)出的陶(tao)瓷(ci)(ci)閥門來代替(ti)金屬閥門,是近年(nian)來閥門材料應(ying)用(yong)領域(yu)的重大(da)創(chuang)新(xin)之(zhi)舉。
陶瓷閥(fa)(fa)(fa)門(men)(men)(men)相較金屬(shu)閥(fa)(fa)(fa)門(men)(men)(men)而(er)言具有更多的(de)(de)(de)(de)(de)優點(dian),其一,陶瓷材(cai)料(liao)制成的(de)(de)(de)(de)(de)閥(fa)(fa)(fa)門(men)(men)(men)提(ti)(ti)高(gao)了(le)其耐(nai)磨(mo)性(xing)、防腐(fu)性(xing)及密封性(xing),大(da)(da)大(da)(da)延(yan)長了(le)閥(fa)(fa)(fa)門(men)(men)(men)的(de)(de)(de)(de)(de)使用(yong)(yong)壽命;其二,陶瓷閥(fa)(fa)(fa)門(men)(men)(men)的(de)(de)(de)(de)(de)使用(yong)(yong)可以大(da)(da)幅度降(jiang)低閥(fa)(fa)(fa)門(men)(men)(men)維(wei)修和更換的(de)(de)(de)(de)(de)次數,提(ti)(ti)高(gao)配套設備運(yun)行的(de)(de)(de)(de)(de)安全性(xing),穩定性(xing),減輕工人(ren)的(de)(de)(de)(de)(de)勞動強度,節約設備的(de)(de)(de)(de)(de)維(wei)修費用(yong)(yong);其三(san),陶瓷閥(fa)(fa)(fa)門(men)(men)(men)的(de)(de)(de)(de)(de)使用(yong)(yong),能(neng)(neng)提(ti)(ti)高(gao)工業管路系統的(de)(de)(de)(de)(de)密封性(xing),同時能(neng)(neng)高(gao)度的(de)(de)(de)(de)(de)杜(du)絕泄露,積極推(tui)動環(huan)境保護。其四,制造陶瓷的(de)(de)(de)(de)(de)材(cai)料(liao)廉價,并能(neng)(neng)節約大(da)(da)量金屬(shu)材(cai)料(liao)和稀有礦產(chan)資源,大(da)(da)大(da)(da)提(ti)(ti)高(gao)了(le)經濟效(xiao)益。
隨著我國閥(fa)(fa)門工(gong)業(ye)技(ji)術的日臻成(cheng)熟(shu)和閥(fa)(fa)門市場的需求(qiu)擴大,陶瓷(ci)閥(fa)(fa)門已(yi)普遍應用在諸多(duo)大型特殊(shu)工(gong)況環(huan)境的成(cheng)套(tao)裝置(zhi)上,國內生產(chan)陶瓷(ci)閥(fa)(fa)門的企(qi)業(ye)也(ye)不(bu)止上鍋企(qi)業(ye)一家。正是依靠科技(ji)創新改變思路,我國的閥(fa)(fa)門工(gong)業(ye)才得(de)以快(kuai)速(su)、穩步發(fa)展壯大起來。(文/SUNMEDIA)
