(偏芯旋轉閥)氣動偏芯半球閥適用于泥漿和含有纖維介質，以及含有微小固體懸浮物的介質，廣泛應用于石油、化工、造紙、污水處理等管道中做開關切斷或流量調節 retz (Partial core rotary valve) imported pneumatic partial core hemispherical valve is suitable for mud and media containing fibers, as well as media containing small suspended solids. It is widely used in pipelines such as petroleum, chemical, papermaking, sewage treatment, etc. for switch off or flow regulation

進口氣動偏芯半球閥產品詳情 Product details

氣動偏芯半球閥采用偏心軸旋轉來控制流體的角行程偏芯旋轉閥。閥芯的回轉中心不與旋轉軸同心，可減少磨損，閥芯后部設有一個導流翼，有利于流體穩定流動，半球體中線與閥桿中線偏置尺寸，與閥座中線偏置尺寸，全開時球體與閥座完全脫開，并有一定的間隙，回轉半徑分為長半徑和短半徑，在長半徑轉動軌跡的切線會與閥座密封面形成一個θ角，在閥門啟閉時，半球相對閥座面有一個漸出脫離和漸入擠壓的作用，從而降低了啟閉時閥座與半球之間的機械磨損和擦傷，提高了使用壽命 RETZ品牌 (eccentric rotary valve) The inlet pneumatic eccentric hemisphere valve uses eccentric shaft rotation to control the angular stroke eccentric rotary valve of fluid. The rotation center of the valve core is not concentric with the rotation axis, which can reduce wear. A guide wing is set at the rear of the valve core, which is conducive to stable fluid flow. The center line of the hemisphere is offset from the center line of the valve stem, which is offset from the center line of the valve seat. When the valve is fully opened, the sphere and the valve seat are completely separated, and there is a certain gap. The rotation radius is divided into long radius and short radius. The tangent line of the rotation track at the long radius will form a gap with the sealing surface of the valve seat θ Angle, when the valve is opened and closed, the hemisphere has a gradual separation from the valve seat surface and a gradual extrusion effect, thus reducing the mechanical wear and abrasion between the valve seat and the hemisphere during opening and closing, and improving the service life

進口氣動偏芯半球閥特點Characteristic

1.球體和閥座完全脫離，消除了密封圈的磨損，克服了傳統球體閥座與球體密封面始終磨損的問題，非金屬彈性材料被嵌入金屬座中，閥座金屬面受到良好的保護 The ball and the valve seat are completely separated, which eliminates the wear of the sealing ring and overcomes the problem that the traditional ball valve seat and the ball sealing surface are always worn. The non-metallic elastic materials are embedded in the metal seat, and the metal surface of the valve seat is well protected

2.半球切口具有切削功能，在關閉時能將介質中的雜物切斷，保證閥門正常啟閉 The hemispherical notch has the cutting function, which can cut off the sundries in the medium when it is closed to ensure the normal opening and closing of the valve

3.半球用雙金屬，母材上堆焊不同的合金，閥座也作相應堆焊經特殊的處理，密封面組合成防腐、耐磨、高強度等各種類型，滿足進口氣動偏芯半球閥4.jpg不同場合需求 Hemisphere bimetal, different alloys are surfacing welded on the base metal, and the valve seat is also subject to corresponding surfacing. After special treatment, the sealing surface assembly is made of anti-corrosion, wear-resistant, high-strength and other types to meet the needs of different occasions

4.開閉迅速，從全開到全關只要旋轉90°，便于遠距離的控制 It can be opened and closed quickly, and only needs to rotate 90 ° from full opening to full closing, which is convenient for remote control
