閥門是管路流體輸送系統(tǒng)中控制部件，用來改變通路斷面和介質(zhì)流動方向，具有導(dǎo)流、截止、節(jié)流、止回、分流或溢流卸壓等功能。用于流體控制的閥門，從**簡單的截止閥到極為復(fù)雜的自控系統(tǒng)中所用的各種閥門，其品種和規(guī)格繁多，閥門的公稱通徑從極微小的儀表閥大至通徑達10m的工業(yè)管路用閥?？捎糜诳刂扑?、蒸汽、油品、氣體、泥漿、各種腐蝕性介質(zhì)、液態(tài)金屬和放射性流體等各種類型流體地流動，閥門的工作壓力可以從的超高壓，工作溫度可以c-270℃的**溫到1430℃的高溫。閥門的控制可采用多種傳動方式，如手動、電動、液動、氣動、渦輪、電磁動、電磁液動、電液動、氣液動、正齒輪、傘齒輪驅(qū)動等；可以在壓力、溫度或其它形式傳感信號的作用下，按預(yù)定的要求動作，或者不依賴傳感信號而進行簡單的開啟或關(guān)閉，閥門依靠驅(qū)動或自動機構(gòu)使啟閉件作升降、滑移、旋擺或回轉(zhuǎn)運動，從而改變其流道面積的大小以實現(xiàn)其控制功能。

加強憂患意識，強化企業(yè)文化及市場服務(wù)理念，只有做到穩(wěn)中求快、快中求精、精中求穩(wěn)，才能讓企業(yè)在競爭日益激烈的泵閥行業(yè)大潮中求生存、謀發(fā)展。社會是個信息的時代，企業(yè)在產(chǎn)品上遇到競爭對手在所難免，行業(yè)存在競爭，對于一些企業(yè)來講反而是件好事。因為有了競爭，企業(yè)提高了產(chǎn)品質(zhì)量，提高了服務(wù)質(zhì)量，消費者也用更少的錢獲得了更好或者更多的消費和服務(wù)。市場是一個“篩子”，行業(yè)在發(fā)展進步的同時，市場也在優(yōu)勝劣汰著行業(yè)內(nèi)的企業(yè)。雖然目前球閥行業(yè)發(fā)展的現(xiàn)狀勢頭正盛，國家扶持政策給予較大改觀，市場需求量也不斷加大，泵閥行業(yè)由于行業(yè)內(nèi)的激烈競爭也使得國內(nèi)泵閥相關(guān)技術(shù)精益求精，但是眾多干擾因素表明，泵閥行業(yè)的發(fā)展前景不容樂觀。參考資料1.陸亞俊，馬**良，鄒平華．《暖通空調(diào)》：中國建筑工業(yè)出版社。</p><div
