style="text-indent:25px">閥門型號(hào)編排：閥門型號(hào)通常應(yīng)表示出閥門類型、驅(qū)動(dòng)方式、連接形式、結(jié)構(gòu)特點(diǎn)、密封面材料、閥體材料和公稱壓力等要素。閥門型號(hào)的標(biāo)準(zhǔn)化對(duì)閥門的設(shè)計(jì)、選用、銷售提供了方便。當(dāng)今閥門的類型和材料越來(lái)越多，閥門的型號(hào)編制也愈來(lái)愈復(fù)雜。我國(guó)雖有閥門型號(hào)編制的統(tǒng)一標(biāo)準(zhǔn)，但愈來(lái)愈不能適應(yīng)閥門工業(yè)發(fā)展的需要。目前，閥門制造廠一般采用統(tǒng)一編號(hào)方法；凡不能采用統(tǒng)一編號(hào)的方法，各制造廠均按自己的需要制訂編號(hào)方法。《閥門型號(hào)編制方法》適用于工業(yè)管道用閘閥、節(jié)流閥、球閥、蝶閥、隔膜閥、柱塞閥、旋塞閥、止回閥、安全閥、減壓閥、疏水閥。它包括閥門的型號(hào)編制和閥門的命名。運(yùn)輸過程中要采取措施保證包封不破損。青島閥門批發(fā)廠家</p><p

style="text-indent:25px">閥門采購(gòu)事項(xiàng)：閥門規(guī)格及類別，應(yīng)符合管道設(shè)計(jì)文件的要求。1、閥門的型號(hào)應(yīng)注明依據(jù)的國(guó)標(biāo)編號(hào)要求。若是企業(yè)標(biāo)準(zhǔn)，應(yīng)注明型號(hào)的相關(guān)說明。2、閥門工作壓力，要求≥管道的工作壓力，在不影響價(jià)格的前提下，閥門可承受的工壓應(yīng)大于管道實(shí)際的工壓。3、閥門制造標(biāo)準(zhǔn)，應(yīng)說明依據(jù)的國(guó)標(biāo)編號(hào)，若是企業(yè)標(biāo)準(zhǔn)，采購(gòu)合同上應(yīng)附企業(yè)文件。閥門的性能檢測(cè)：1、閥門某一規(guī)格批量制造時(shí)，應(yīng)委托**性機(jī)構(gòu)進(jìn)行以下性能的檢測(cè)：①閥門在工壓狀況下的啟閉力矩；②閥門在管道輸水狀況下的流阻系數(shù)的檢測(cè)。2、閥門在出廠前應(yīng)進(jìn)行以下的檢測(cè)：①閥門在開啟狀況下，閥體應(yīng)承受閥門工壓值二倍的內(nèi)壓檢測(cè)；②閥門在關(guān)閉狀況下，兩側(cè)分別承受11倍閥門工壓值，無(wú)滲漏；但金屬密封的蝶閥，滲漏值亦不大于相關(guān)要求。江蘇閥門廠家電話</p></p><br
