Description

一种筒塞平衡式流量控制阀
本发明公开了“一种筒塞平衡式流量控制阀”，它属于水电领域里的水库大坝蓄水，城市供水，工业供水，管道上的大型控制阀门方面的发明创造。其任务是针对现有的“多功能活塞式流量控制阀”，在使用过程中存在着阀芯缸筒偏心力大，由于曲柄采用90度回转，它的力臂较长，这对阀芯缸筒运动是极其不利的，易造成其上下倾斜力产生的偏心，使阀芯缸筒与节流套筒两端导向环磨损加快，从而影响使用寿命。此外阀芯缸筒和节流套筒在制造结构上还存在着结构繁琐，自重力过大等问题，并且流通介质受阀体流道腔的制约，介质流向采用左进右出方式，当介质流通时，在右出口端介质会产生集中对流现象，这就要造成压降损失大，同时阀门有振动，噪音也大，尤其是大口径阀门，这类问题弊端突出明显。因此本发明克服上述缺点，提供一种机构简单，技术完善，使用可靠，成本较低，它将阀芯设计为梯形无底缸筒，并具有平衡压差，消除噪音的功效。本发明阀芯缸筒分为两节，一节为密封无孔圆筒(左部)，另一节为调节带孔圆筒(右部)，两个圆筒一大，一小为一体，其密封圆筒两端设有锥度密封面，调节圆筒设有笼式Cv值调节孔，用来调节流量和抗噪音之用，它筒内还设有法兰与双梁接合成一体。此外节流套筒周缘上设有许多节流抗噪音孔，它比调节缸筒小孔大出1/3，其两端跨度大，有利导向和密封，并设有内凸沿为导向环和锥度密封面，它与阀芯缸筒配合调节流量，密封介质，使阀门控制具有多功能流量特性。
本发明主要由电动装置，阀内件，主阀体和副阀体构成，主阀体内腔设有夹层内腔，其内腔设有支架，排积物流道口，阀轴通孔，阀轴设计在侧面，由滑动轴套定位，再由电动装置带动阀轴120度回转，阀轴里面(夹层内腔)与曲柄六角配合成一体，阀轴端部插入支架轴套里，这样就把阀轴牢牢的定位住，其曲柄上安有连杆，连杆再连接双梁，使之带动阀芯缸筒运动，实现过程或切断控制。
本发明设有阀芯缸筒和节流套筒，它们由一大，一小圆筒组合套在一起，靠两端锥度面密封，节流套筒由副阀体法兰压接，固定在主阀体内腔夹层端部，经流体流过，则阀芯缸筒在节流套筒里由电装带动，左右运动，控制流量，以满足工况控制要求。
本发明结构简单，实用性强，性能可靠，使用寿命长，制造成本较低，是目前理想的创新型的好产品。
说明书附图1是本发明的结构主剖视图。图中：1主阀体；2.腔底支架；3.阀轴；4、16、26、32.螺柱；5、17、27、33.螺母；6.盲板；7.曲柄；8、12.圆销；9.连杆；10.节流套筒；11.双梁；13.阀芯缸筒；14.副阀体；15.组合垫；18.内角螺钉；19、24.O形圈。如附图1和附图2所示。

图3是图1的左视图。图中：有AB两处局部图，双梁11安装在阀芯缸筒13内法兰上，并且靠在法兰背面，由内六角螺钉固定上下两处，使之跟阀芯缸筒13成一体。如附图1和附图3所示。
下面结合附图对本发明的实施例加以说明其工作原理。
1.阀门开启时：
电动装置28逆时针转动，带动阀轴3随之转动，则曲柄7也逆时针转动，带动连杆9和双梁11小偏心摇动，同时阀芯缸筒13向左移动，此时阀芯缸筒13的密封端面逐渐打开，调节端面也逐渐打开，至此介质通过阀芯缸筒13的调节孔流入节流套筒10的筒孔，之后介质进入主阀体1流道腔，从阀门左侧流出，即：阀门从O度转到120度，致阀门开启。
2.阀门关闭时：
电动装置28顺时针转动，带动阀轴3和曲柄7顺时针转动，使连杆9和双梁11摇动，此时阀芯缸筒13向右移动，则阀芯缸筒13的密封端面和调节端面同时逐渐关闭，形成密封，阀门关闭到位。
本发明“一种筒塞平衡式流量控制阀”，是对现有的“多功能活塞式流量控制阀”结构性的改变和寿命上的提高，这种新型控制阀，彻底解决了导向环磨损快，偏心力大，同轴度差，使用寿命短等突出问题。
