1.用鐵、碳鋼制造閥門(mén)和修復(fù)廢品閥門(mén)以次棄好的閥門(mén)產(chǎn)品，這類(lèi)產(chǎn)品一般在硬度和精度上存在很大誤差；<br/> 2.將劣質(zhì)低價(jià)的閥門(mén)、地方小廠的閥門(mén)產(chǎn)品打上大品牌廠商的注冊(cè)商標(biāo)，這類(lèi)產(chǎn)品一般在品牌形象上以假亂真，以達(dá)到欺騙消費(fèi)者的目地；<br/> 3.假冒***大廠的用戶(hù)、經(jīng)銷(xiāo)商、代理商，甚至假冒廠家現(xiàn)貨門(mén)市部；<br/> 4.制作鋼印，把普通級(jí)閥門(mén)打字變成D級(jí)閥門(mén)；<br/> 5.在質(zhì)量閥門(mén)產(chǎn)品里攙入假貨出售；<br/> 6.在產(chǎn)品價(jià)格上欺騙消費(fèi)者，根據(jù)消費(fèi)者對(duì)閥門(mén)產(chǎn)品的實(shí)際了解情況以次充好，以假貨代替真貨出售；<br/> 如何分辨閥門(mén)真假？<br/> 1.外觀方面首先以閥門(mén)的軸體顏色為出色點(diǎn)進(jìn)行辨別。<br/> 閥門(mén)的外觀顏色可以充分的反應(yīng)出閥門(mén)產(chǎn)品的材質(zhì)情況，對(duì)于大多數(shù)的假冒閥門(mén)產(chǎn)品來(lái)說(shuō)，一般均是在鋼材的選用上下文章。<br/> 大家都知道，鋼材價(jià)格也是決定著閥門(mén)產(chǎn)品價(jià)格的一個(gè)重要原因，因此一些商家則在鋼材使用上大下文章，降低鋼材型號(hào)，以次充好。使用普通鋼材、碳鋼、瑪鋼等材質(zhì)，更有甚者還會(huì)使用鐵管來(lái)代替鋼材產(chǎn)品。<br/> </p><p>
