Description

煤浆控制用新型调节阀
技术领域
本发明涉及一种煤浆控制用新型调节阀。
背景技术
在煤化工用阀领域，煤化工选用调节阀，多采用直通式调节阀和偏心旋转调节阀，由于直通式调节阀S型的流道设计，煤粉对阀腔的冲刷是非常严重的，这也是目前的束手的问题。偏芯旋转调节阀在小开度范围内，由于间隙流而无法克服煤粉对阀芯的冲刷，也无法克服。随着煤化工工况对调节阀的要求越来越高，现有的结构无法满足煤化工恶劣工况的需求，
发明内容
本发明的目的是提供一种煤浆控制用新型调节阀，能够在具备流量调节功能的同时具有较强的抗冲刷能力。
一种煤浆控制用新型调节阀，包括主轴、阀体和阀芯，其特别之处在于：所述阀芯的上端与主轴连接而其下端与副轴连接，该副轴安装在所述阀体上，在该阀芯上开有V型窗口，并且该V型窗口的顶端为球形表面。
其中在阀芯旁的阀体出口处的内表面上设有耐磨合金衬套，耐磨合金衬套材质为YG11合金，合金厚度范围在5-10mm。
其中耐磨合金衬套为圆管状，并且该耐磨合金衬套靠近阀芯的一端内壁上设有斜面。
其中阀芯采用HG11合金。
经过试用证明，采用本发明的调节阀后，解决了煤化工工况下煤粉对阀腔及阀芯的冲刷问题，有效延长了调节阀的使用寿命，同时也解决了煤化工用调节阀阀国产化的需求。
附图说明
附图1为本发明的结构示意图；
附图2为本发明中阀芯2的结构示意图；
附图3为本发明中阀芯2的结构示意图；
附图4为本发明中阀芯2的剖视图；
附图5为图4的C-C剖视图。
具体实施方式
如图1、2、3、4、5所示，本发明是一种煤浆控制用新型调节阀，包括主轴1、阀体3、阀座和阀芯2，所述阀芯2的上端与主轴1连接而其下端与副轴连接，该副轴安装在所述阀体3上，在该阀芯2上开有V型窗口，并且该V型窗口的顶端为球形表面。
其中在阀芯2旁的阀体3出口处的内表面上设有耐磨合金衬套，耐磨合金衬套为YG11合金，合金厚度范围在5-10mm。该耐磨合金衬套为圆管状，并且该耐磨合金衬套靠近阀芯2的一端内壁上设有斜面。另外阀芯2采用HG11合金。
本发明的工作原理和使用方法是：当主轴1受到驱动器驱动时带动球芯（阀芯2）转动，球芯在打开过程中，V型窗口与阀座之间形成不同面积的流道，从而实现流量的调节与抗冲刷功能，对球芯的阀座具有自清洁功能，当球芯窗口转过90°时，便与阀座形成密封效果。
