歐通截止閥屬于強(qiáng)制密封式閥門,，所以在閥門關(guān)閉時(shí),，必須向閥瓣施加壓力,，以強(qiáng)制密封面不泄漏,。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門時(shí),，操作力所需要克服的阻力,，是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關(guān)閥門的力比開閥門的力大,，所以閥桿的直徑要大,，否則會發(fā)生閥桿頂彎的故障。按連接方式分為三種：法蘭連接,、絲扣連接,、焊接連接。從自密封的閥門出現(xiàn)后,，截止閥的介質(zhì)流向就改由閥瓣上方進(jìn)入閥腔,，這時(shí)在介質(zhì)壓力作用下，關(guān)閥門的力小,，而開閥門的力大,，閥桿的直徑可以相應(yīng)地減少。同時(shí),，在介質(zhì)作用下,，這種形式的閥門也較嚴(yán)密。系列產(chǎn)品：進(jìn)口截止閥,、高壓截止閥,。高溫截止閥。高壓高溫截止閥,。電動截止閥J941H/J961Y,。氣動截止閥J641H。氣動角座閥,。日標(biāo)截止閥J41W,。德標(biāo)截止閥。美標(biāo)截止閥J41W,。保溫截止閥BJ41H/BJ45,。高溫截止閥J41Y/J61Y。高壓截止閥J41H,、對焊截止閥J61Y/J65Y/J64H,。高溫高壓截止閥。Y形截止閥J45/J65Y,。自密封截止閥J41W/J61W,。黃銅截止閥J11W,。鑄鐵截止閥J41TW。鑄鋼截止閥J41H,。鍛鋼截止閥,。不銹鋼截止閥J41W。鉻鉬鋼截止閥J41Y-100I,。波紋管截止閥WJ41/WJ44/WJ61H,、保溫波紋管截止閥BWJ41W。絲口截止閥J11W,。法蘭截止閥J41,。氧氣截止閥JY41W,。真空截止閥NKJ41H/44H/J61,。水封截止閥DS41H/DS61H。傘齒輪截止閥J541H,。氨用截止閥J41B/J42B/J61B/J21B/J11B,。角式截止閥J44H。襯氟截止閥J41F4/J45F4,。襯膠截上閥J41J/J45J,。塑料截止閥J41F-6S、J11F-6S,。液化氣截止閥J41F,。天燃?xì)饨刂归yJ41N。低溫截止閥DJ41W,。撞擊式大口徑截止閥,。蒸汽截止閥。斯派沙克式截止閥,。節(jié)流閥,、高壓節(jié)流閥、截止節(jié)流平衡閥L41Y/L44Y/L46Y/L86Y/L87Y/L66Y/L67Y/L47Y,。節(jié)流截止放空閥FJ41Y,。節(jié)流截止排污閥TPJ41Y。 閥體的材質(zhì)有: 鑄鐵,、鑄鋼,、不銹鋼、鍛鋼,、鉻鉬鋼,、鉻鉬釩鋼。工作壓力1.6-32MPA(美標(biāo)從150LB-2500LB,，日標(biāo)從10K-64K),。工作溫度-20℃- 550°C。閥門口徑從DN15-DN300。連接方式:法蘭,、絲口或焊接,。驅(qū)動方式:手動、電動,、氣動,、傘齒輪、正齒輪轉(zhuǎn)動,。適用介質(zhì):水,、油品、氣,、蒸汽等,。截止閥簡介:截止閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面,，閥瓣沿流體的中心線作直線運(yùn)動,。閥桿的運(yùn)動形式，有升降桿式（閥桿升降,，手輪不升降）,，也有升降旋轉(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）,。截止閥只適用于全開和全關(guān),，不允許作調(diào)節(jié)和節(jié)流。“好閥門.歐通造”不僅是歐通人永恒的追求,，更是對廣大用戶質(zhì)量和服務(wù)的摯誠承諾,！
