PQ340F、PQ340H上裝偏心半球閥
偏心式半球閥是一種新型閥門,是為解決溶液及礦漿等兩相流介質(zhì)輸送中的技術難題而研制開發(fā)的新型產(chǎn)品,本產(chǎn)品*了國內(nèi)閥門品種的一項空白的國產(chǎn)化系列產(chǎn)品,其結構上采用了偏心—楔緊原理,通過傳動機構達到閘緊,調(diào)節(jié),啟閉的作用。本產(chǎn)品結構新穎,性能穩(wěn)定,開啟迅速輕便,磨損自動補償,密封可靠耐用,易于調(diào)整維修;直通式結構流通面積大,較截止閥、蝶閥等閥門阻尼小,系統(tǒng)降壓?。荒軌蜃孕衅瞥Y垢,方便啟閉,無“死區(qū)”,克服了閘閥、球閥、截止閥等易結疤,易堵塞、易泄漏、壽命短等弊端,顯示了*的*性。雙偏心式半球閥系列產(chǎn)品,貫徹了國家標準GB9113、8-11-88尺寸系列法蘭連接,便于安裝及替代現(xiàn)有閥門品種,亦可根據(jù)用戶需要的連接尺寸系列安排生產(chǎn),適應不同工礦條件下的需要。

結構特點及用途
1、 電動偏心半球閥壓力損失?。喝_時水損為零,流道*暢通,且介質(zhì)不會沉積在閥體中腔內(nèi)。
2、 耐顆粒磨損:V型開口的球冠與金屬閥座之間具有剪切作用,在關閉過程中,只在zui后一刻球冠才靠向閥座,不形成磨擦,且閥座耐磨的鎳合金制成,不易被沖刷磨損,因而適用于含纖維、微小固體顆粒、漿等。
3、 適合高流速介質(zhì):直通流道,堅固的偏心一曲軸使之適合高流速且無振動。
4、 壽命長:無易損部件,由于偏心作用,閥門啟閉時密封面間無磨擦,則使用壽命長。
5、 維修方便:閥門維修時不需從管路上拆下,只要打開閥蓋即可進行維修
6、 氣動偏心半球閥廣泛適用于水、污水、含微小固體顆粒、水、蒸汽、煤氣、天然氣、油品等。
Structural characteristics and uses
1、 little pressure loss: water loss is zero at full open, compley smooth flow, which will not be deposited on dielectric Valve cavity.
2、 Bears the particles attrition: V shape opens the mouth between the ball crown and the metal valve seat the action is shear, in the closure process, only then depends on in last the moment ball crown to the valve seat, does not form the friction, also the valve seat makes with the wear-resisting nickel alloy, is not easily washed out the attrition, thus is suitable to contains the textile fiber, the small solid particle, the thick liquid and so on.
3、 Suitable for high-velocity media: Direct flow, solid eccentric crank ,make it suitable for high speed without vibration.
4、 Long life: no vulnerable parts, there is no friction between the sealing surface when the valve opens and close due to the function of the eccentric, therefore there is long life.
5、 Easy maintenance: Valve repair without remove from the pipeline, as long as the valve cover is opened for maintenance.
6、 Widely used in water, sewage, containing tiny solid particles, water, steam, gas, oil, etc.
