H46H/W法蘭雙瓣旋啟式止回閥結(jié)構(gòu)圖

適用范圍

H46H/W法蘭雙瓣旋啟式止回閥具有結(jié)構(gòu)簡單、止回動作快、密封性能好、安裝方便、不受空間位置限制、體積小、維修方便等特點(diǎn)。廣泛應(yīng)用于石化、冶金、電力、輕工、食品等行業(yè),水,油品,蒸汽,酸堿性液體均可使用,實(shí)現(xiàn)自動止回。

結(jié)構(gòu)特點(diǎn)

  1. 結(jié)構(gòu)長度短,其結(jié)構(gòu)長度只有傳統(tǒng)法蘭止回閥的1/4~1/8;

  2. 體積小、重量輕,其重量只有傳統(tǒng)法蘭止回閥的1/4~1/20;

  3. 閥瓣關(guān)閉快速,水錘壓力??;

  4. 水平管道或垂直管道均可使用,安裝方便;

  5. 流道通暢、流體阻力??;

  6. 動作靈敏、密封性能好;

  7. 閥瓣行程短、關(guān)閥沖擊力?。?/p>

  8. 整體結(jié)構(gòu)、簡單緊湊、造型美觀;

  9. 使用壽命長、可靠性高。

旋啟式止回閥特性對比

結(jié)構(gòu)
形式
H46型對夾式雙瓣旋啟式止回閥H44型法蘭單瓣旋啟式止回閥
水錘
壓力
水,閥瓣行程短、且有彈簧輔助關(guān)閉、關(guān)閥速度快很大,閥瓣行程長,需要較長的關(guān)閉時(shí)間
H76型的水錘壓力只有H44型的1/2~1/5
尺寸
重量
結(jié)構(gòu)長度很短、體積小、重量輕。
為閥門的安裝、搬運(yùn)、存放及管道的布置帶來很大的便利,并能大量節(jié)約材料、降低造價(jià)
結(jié)構(gòu)長度很長,體積笨大,重量很重
H76型的結(jié)構(gòu)長度只有H44型的1/4~1/6,H76型的重量只有H44型的1/4~1/10
流體
阻力
小,流體阻力系數(shù)ξ為2.6~0.7。
隨著閥門口徑的增大,流體阻力系數(shù)減小。
小,流體阻力系數(shù)ξ為1.3~3,
但低壓工況下,閥瓣不能完全開啟,流體阻力大。
流體阻力隨著閥門口徑的增大而增大。
安裝可水平安裝或垂直安裝,重量輕,不必為閥門設(shè)置支座。可水平安裝或垂直安裝,
大口徑閥門重量重,需設(shè)置支座
開啟
壓力
很小,閥瓣在很小的壓差下就能完全打開較大,閥瓣在較大的壓差下才能完全打開
可靠性閥門為整體結(jié)構(gòu),簡單緊湊。
閥門關(guān)閉時(shí)沖擊力小,水錘壓力小,閥門壽命長,可靠性高。
閥門關(guān)閉時(shí)的巨大沖擊力及水錘壓力容易損壞閥門
