軟密封切斷就不如硬密封切斷好。如全功能超輕型調(diào)節(jié)閥，密封而堆有耐磨合金保護(hù)，可靠性高，泄漏率達(dá)10～7，已經(jīng)能夠滿足切斷閥的要求。閥門國(guó)內(nèi)現(xiàn)狀編輯在閥門生產(chǎn)和研發(fā)的技術(shù)支持上，國(guó)內(nèi)閥門并不比國(guó)外閥門落后，相反很多的產(chǎn)品在技術(shù)和創(chuàng)新上已經(jīng)可以和國(guó)際企業(yè)相媲美。國(guó)內(nèi)閥門行業(yè)的發(fā)展正在往**現(xiàn)代化的方向前行。在工業(yè)化、城市化、**和全球化四大力量推動(dòng)下，我國(guó)閥門裝備制造業(yè)前景還是寬廣的，未來(lái)閥門產(chǎn)業(yè)**化、國(guó)產(chǎn)化，現(xiàn)代化、將是今后閥門行業(yè)發(fā)展主要方向。追求不斷的創(chuàng)新，為閥門企業(yè)創(chuàng)造出新的市場(chǎng)，才能讓企業(yè)在競(jìng)爭(zhēng)日益激烈的泵閥行業(yè)大潮中求生存、謀發(fā)展。隨著閥門技術(shù)的不斷發(fā)展,閥門應(yīng)用領(lǐng)域的不斷拓寬,與之對(duì)應(yīng)的閥門標(biāo)準(zhǔn)也越來(lái)越不可或缺。閥門行業(yè)產(chǎn)品進(jìn)入一個(gè)創(chuàng)新的時(shí)期,不僅產(chǎn)品類別需要更新?lián)Q代,企業(yè)內(nèi)部管理也需要根據(jù)行業(yè)的標(biāo)準(zhǔn)深化**。因此，需要在充分運(yùn)用現(xiàn)有標(biāo)準(zhǔn)的同時(shí),展望未來(lái),研究出能夠運(yùn)用于將來(lái)的新標(biāo)準(zhǔn)和新體系,從而推進(jìn)閥門技術(shù)更高層次的發(fā)展。未來(lái)閥門行業(yè)將朝著兩大主方向發(fā)展：一是由單一品種向多品種和多規(guī)格發(fā)展;二是朝著節(jié)能方向發(fā)展。業(yè)內(nèi)人士稱，泵閥企業(yè)只有有效清晰地認(rèn)識(shí)行業(yè)現(xiàn)狀，不斷加強(qiáng)優(yōu)化自身產(chǎn)品。</p><div
