style="font-size:16px;">眾所周知閥門口徑大小與管道的尺寸有著必然的聯(lián)系，通常說多大的管徑(外徑)配多大的閥門。而閥門口徑則需要根據(jù)實際參數(shù)來計算，一般來說管道都會較大一些，閥門實際要比較小，主要取決于閥門位置需要控制的流量大小是多少，而管道尺寸只需要流通能力夠就行了。一般成人的水平極限輸出力為60-90kg，視不同體質(zhì)而言。閥門是一種用途極為的設(shè)備，幾乎可以在任何地方找到，閥門活躍在街道下、房屋里、發(fā)電廠和造紙廠、精煉廠以及各種各樣的基礎(chǔ)設(shè)施和工業(yè)設(shè)施中。一般截止閥的流向設(shè)計為低進高出，當人對閥門進行關(guān)閉時，人體水平推動手輪轉(zhuǎn)動，使閥瓣向下運動，實現(xiàn)關(guān)閉，這時需要克服三個方面的力的組合，即：1)軸向頂推力Fa；2)填料與閥桿磨擦力Fb。</span>

style="font-size:16px;">閥門是流體輸送系統(tǒng)中的控制部件，具有截止、調(diào)節(jié)、導(dǎo)流、防止逆流、穩(wěn)壓、分流或溢流泄壓等功能。其品種規(guī)格多、用途廣、用量大，可分為工業(yè)閥門及民用閥門。工業(yè)閥門主要用于調(diào)節(jié)工業(yè)自動化過程控制領(lǐng)域中的介質(zhì)流量、壓力、溫度、液位等工藝參數(shù)。工業(yè)閥門的全球銷售總額預(yù)計今年將超過645億美元。總體而言，市場在以每年大約3-4%的速度增長。在大多數(shù)國家，CFT產(chǎn)品(涉及燃燒、流體和處理的產(chǎn)品)的增速都比GDP(國民生產(chǎn)總值)的增速高1%，比如GDP的增速是2%，CFT產(chǎn)品的銷售額增速為3%，如果GDP的增速是7%，那么CFT產(chǎn)品的銷售額增速則是8%。礦業(yè)也為閥門提供了若干市場增長點，例如鋰加工。礦業(yè)的特點是各個國家之間，規(guī)模和發(fā)展速度千差萬別。有些國家的礦石開采成本較低，市場的發(fā)展呈井噴狀態(tài)，有些國家的開采成本較高，銷售額甚至在下降。</span>
