進口斜盤式止回閥，斜板式無撞擊逆止閥慨述 Express with regret

斜盤式止回閥（斜板式無撞擊逆止閥）采用雙偏心閥瓣，關閉時閥痤與密封面逐步接觸，達到無撞擊、無噪聲工作。微彈性金屬閥座，密封性能好 RETZ The swashplate check valve (swashplate non impact check valve) adopts double eccentric valve clack. When closing, the valve disc contacts the sealing surface gradually, so that it can work without impact and noise. Micro elastic metal valve seat with good sealing performance

斜盤式止回閥（斜板式無撞擊逆止閥）的閥座密封是斜圓錐體的一部分，閥座與閥瓣間形成的密封線為近似橢圓形曲線，該曲線所在平面與閥門流道中心線的夾角為60°；近似橢圓密封線的長軸中心與錐體軸線形成一個角度偏心，即閥座密封面所在圓錐體的軸線和閥體流道中心線之間形成第二個偏心夾角為15°-20°；閥瓣旋轉軸的軸線相對于圓錐體的軸線形成一偏心量，且相對于密封線所在平面也處于偏心位置，形成一偏心量。當介質的壓力達到其工作壓力時，閥瓣就開啟，當介質的壓力降低后，蝶狀斜盤閥瓣就自動關閉。因該閥瓣與金屬閥座具有三偏心蝶閥的特征，這種結構使得閥瓣能夠進行鐘擺式運動。圓盤斜角形閥座和漏斗形閥瓣結合和分離期間都不會出現摩擦或滑動接觸。在關閉時它能迅速地在無須借助外力的情況下，與閥座幾乎無沖擊。無碰撞而實現密封。同時它具有大流量小流阻的特性

The valve seat seal of swashplate check valve (swashplate non impact check valve) is a part of the inclined cone. The sealing line formed between the valve seat and the valve clack is an approximate elliptic curve, and the included angle between the plane of the curve and the center line of the valve flow path is 60 °; The long axis center of the approximate elliptical sealing line forms an angular eccentricity with the cone axis, that is, the second eccentric angle formed between the axis of the cone where the valve seat sealing surface is located and the center line of the valve body flow passage is 15 ° - 20 °; The axis of the rotary shaft of the valve flap forms an eccentricity relative to the axis of the cone, and is also in an eccentric position relative to the plane where the sealing line is located, forming an eccentricity. When the pressure of the medium reaches its working pressure, the valve disc will open. When the pressure of the medium decreases, the butterfly swashplate valve disc will automatically close. Because the disc and metal seat have the characteristics of a three eccentric butterfly valve, this structure enables the disc to swing. There is no friction or sliding contact between the disc bevel seat and the funnel disc during engagement and separation. When closing, it can quickly have no impact with the valve seat without external force. Sealing without collision. At the same time, it has the characteristics of large flow and small flow resistance
