【進口氣動V型調(diào)節(jié)球閥】詳細說明:
氣動V型調(diào)節(jié)球閥是球閥的一種,它的關(guān)閉件是半球體上開有V字型開口,V型開口具有鋒利的刃口,在球體回轉(zhuǎn)過程中,關(guān)閉件之間有擦拭作用,對介質(zhì)具有強有力的切斷力,球體的V型開口與閥座流道形成一個扇形區(qū)域,在回轉(zhuǎn)過程中可改變流道截面積,形成對介質(zhì)的精確調(diào)節(jié),氣動V型球閥它是一種角回轉(zhuǎn)的調(diào)節(jié)閥,其密封性能與普通球閥相同,V型調(diào)節(jié)球閥使它同時具備調(diào)節(jié)和開關(guān)兩種功能,與氣動或電動執(zhí)行器配套,廣泛使用于工業(yè)過程自控系統(tǒng)中。
Pneumatic V-shaped regulating ball valve is a kind of ball valve. Its closing parts are V-shaped openings on the hemisphere. V-shaped openings have sharp edges. In the process of ball rotation, there is wiping effect between closing parts, which has strong cutting force on the medium. V-shaped openings of the sphere form a fan-shaped area with the valve seat runner and turn around. During the process, the cross-section area of the flow passage can be changed to form an accurate adjustment of the medium. Pneumatic V-type ball valve is a kind of angular rotary regulating valve. Its sealing performance is the same as ordinary ball valve. V-type ball valve makes it have two functions of regulating and switching at the same time. It is matched with pneumatic or electric actuator and widely used in industrial process automatic control system. Medium.
【進口氣動V型調(diào)節(jié)球閥】特點:
1、氣動V型調(diào)節(jié)球閥閥體整體式結(jié)構(gòu):對夾式和法蘭式V型球閥閥體都是整體側(cè)裝式結(jié)構(gòu),結(jié)構(gòu)剛性強,不容易引起變形和外泄。
2、上下自潤滑軸承:閥體內(nèi)裝有上下自潤滑軸承,與閥桿接觸面積大,承載能力高,磨擦系數(shù)小,使閥門的扭矩減少。
3、V型調(diào)節(jié)球閥閥座可根據(jù)介質(zhì)和工況的需要,選金屬硬密封或PTFE軟密封:金屬硬密封閥座密封表面堆焊硬質(zhì)合金,球 面鍍硬鉻或噴焊、離子氮化等硬化處理,使密封面使用壽命增強,耐溫提高;軟密封PTFE閥座或增強PTFE閥座密封性好 耐腐蝕,適應(yīng)范圍廣。
4、V型調(diào)節(jié)球閥經(jīng)濟實用性:閥體重量輕,閥桿扭矩小,配用氣動或電動執(zhí)行器相應(yīng)規(guī)格小,與其它類型的調(diào)節(jié)閥相比,性價比高。
5,V型調(diào)節(jié)球閥介質(zhì)適應(yīng)范圍廣:由于V型開口與閥座之間的剪切作用力,及閥內(nèi)腔流道的光滑圓整,使介質(zhì)不易積存于內(nèi)腔,所以 它除適合液體介質(zhì)外,更適合于帶纖維及固體顆料介質(zhì)的系統(tǒng)控制。
6、氣動V型調(diào)節(jié)球閥小流量精確控制:通過對小口徑閥芯特殊V型開口的加工,可實現(xiàn)小Cv值精確控制。
【進口氣動V型調(diào)節(jié)球閥】性能結(jié)構(gòu):
V型球閥屬于固定球閥,也是單閥座密封球閥,調(diào)節(jié)性能是球閥中*的,V型球閥流量特性是等百分比的,可調(diào)比達100:1。它的V型切口與金屬閥座之間具有剪切作用,V型球閥特別適合含纖維、微小固體顆粒、料漿等介質(zhì)。
【進口氣動V型調(diào)節(jié)球閥】應(yīng)用:
氣動V型調(diào)節(jié)球閥適用于經(jīng)常操作,啟閉迅速,輕便,流體阻力小,結(jié)構(gòu)簡單,相對體積小,重量輕,便于維修,密封性能好,不受安裝方向的限制,介質(zhì)的流向可任意,無振動,噪聲??;V型調(diào)節(jié)球閥由于球芯帶有V型結(jié)構(gòu),對閥座具有剪切作用。因此氣動V型調(diào)節(jié)球閥適用于造紙、化工、冶金等工業(yè)企業(yè)中含有纖維或微小固體顆粒的懸濁液介質(zhì)中對有關(guān)工藝參數(shù)的控制,特別適用于制漿、造紙生產(chǎn)過程中的紙漿、白水、黑液、白液等懸浮顆粒的流體及濃、濁漿狀流體介質(zhì)的自動調(diào)節(jié)。
