style="text-indent:25px">電站不銹鋼焊接截止閥一旦處于開(kāi)啟狀態(tài)，它的閥座和閥瓣密封面之間就不再有接觸，因而它的密封面機(jī)械磨損較小，由于大部分焊接截止閥的閥座和閥瓣比較容易修理或更換密封元件時(shí)無(wú)需把整個(gè)閥門從管線上拆下來(lái)，這對(duì)于閥門和管線焊接成一體的場(chǎng)合是很適用的。介質(zhì)通過(guò)此類閥門時(shí)的流動(dòng)方向發(fā)生了變化，因此焊接截止閥的流動(dòng)阻力較高于其它閥門。焊接截止閥是一種常用的截?cái)嚅y，主要用來(lái)按通或截?cái)喙苈分械慕橘|(zhì)，一般不用于調(diào)節(jié)流量，焊接截止閥適用的壓力、溫度范圍很大，但一般用于中、小口徑的管道。與閘閥相比，焊接截止閥的結(jié)構(gòu)較簡(jiǎn)單，制造與維修都較方便,密封面不易磨損、擦傷，密封性較好，壽命較長(zhǎng),啟閉時(shí)閥瓣行程較小，啟閉時(shí)間較短，閥門高度較小。大范圍用于給排水、煤氣、電力、冶金、石油、化工、輕紡以及城建等行業(yè)，在蒸汽、水、油類介質(zhì)的管路上作啟閉用。福建日標(biāo)截止閥費(fèi)用電站截止閥所謂的“高低”

style="text-indent:25px">電站截止閥分為三類：直通式截止閥、直角式截止閥及直流式斜截止閥。明顯的優(yōu)點(diǎn)是：在開(kāi)啟和關(guān)閉過(guò)程中，由于閥瓣于閥體密封面間的摩擦力比閘閥小，因而耐磨。開(kāi)啟高度一般*為閥座通道直徑的1/4，因此比閘閥小的多。通常在閥體和閥瓣上只有一個(gè)密封面，因而制造工藝性比較好，便于維修。公稱壓力或壓力級(jí)：PN1.0-16.0MPa、ANSICLASS150-900、JIS10-20K，公稱通徑或口徑：DN10~500、NPS1/2~36"，截止閥連接方式：法蘭、對(duì)焊、螺紋等，適用溫度：-196℃~700℃，</p><p
