进口斜盘式止回阀，斜板式无撞击逆止阀慨述 Express with regret

斜盘式止回阀（斜板式无撞击逆止阀）采用双偏心阀瓣，关闭时阀痤与密封面逐步接触，达到无撞击、无噪声工作。微弹性金属阀座，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

斜盘式止回阀（斜板式无撞击逆止阀）的阀座密封是斜圆锥体的一部分，阀座与阀瓣间形成的密封线为近似椭圆形曲线，该曲线所在平面与阀门流道中心线的夹角为60°；近似椭圆密封线的长轴中心与锥体轴线形成一个角度偏心，即阀座密封面所在圆锥体的轴线和阀体流道中心线之间形成第二个偏心夹角为15°-20°；阀瓣旋转轴的轴线相对于圆锥体的轴线形成一偏心量，且相对于密封线所在平面也处于偏心位置，形成一偏心量。当介质的压力达到其工作压力时，阀瓣就开启，当介质的压力降低后，蝶状斜盘阀瓣就自动关闭。因该阀瓣与金属阀座具有三偏心蝶阀的特征，这种结构使得阀瓣能够进行钟摆式运动。圆盘斜角形阀座和漏斗形阀瓣结合和分离期间都不会出现摩擦或滑动接触。在关闭时它能迅速地在无须借助外力的情况下，与阀座几乎无冲击。无碰撞而实现密封。同时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
