宝德6223型伺服辅助式比例阀/BURKERT6223型比例阀
宝德6223型伺服辅助式比例阀瓣沿着阀体垂直线滑动的止回阀，内螺纹止回阀只能安装在水平管道上，在高压小口径止回阀上阀瓣可采用圆球。蝶式止回阀的阀体形状与截止阀样（可与截止阀通用），因此它的流体阻力系数较大。其结构与截止阀相似，阀体和阀瓣与截止阀相同。阀瓣上部和阀盖下部加工有导向套简，阀瓣导向简可在阀盏导向简内自由升降，当介质顺流时，阀瓣靠介质推力开启，当介质停流时，阀瓣靠自垂降落在阀座上，起阻止介质逆流作用。直通式蝶式止回阀介质进出口通道方向与阀座通道方向垂直；立式升降式止回阀，其介质进出口通道方向与阀座通道方向相同，其流动阻力较直通式小。宝德6223型伺服辅助式比例阀的运动曲线，2为排气阀的运动曲线。纵坐标代表升程h，横坐标为曲轴的转角（或时间）。从图中可以看出气阀的开启和关闭都是比较快的。并且气阀的开启速度总是要高于气阀的关闭速度，这是因为气阀的开启过程是在活塞速度很高的阶段进行的，而气阀的关闭却是在活塞已位移到接近止点位置，活塞速度已经很低的情况下进行的。气阀在启闭过程中，阀片、升程限制器及阀座都将受到交变冲击载荷作用，很容易造成磨损和破坏。宝德6223型伺服辅助式比例阀瓣绕转轴作旋转运动。其流体阻力般小于升降式止回阀，它适用于较大口径的场合。旋启式止回阀根据阀瓣的数目可分为单瓣旋启式、双瓣旋启式及多瓣旋启式三种。单瓣旋启式止回阀般适用于中等口径的场合。大口径管路选用单瓣旋启式止回阀时，为减少水锤压力，采用能减小水锤压力的缓闭止回阀。双瓣旋启式止回阀适用于大中口径管路。
