Description

水处理用低阻节能旋塞阀
技术领域
本实用新型涉及一种水处理用低阻节能旋塞阀,具体地说是用于水处理工程上流阻相对较小的节能型旋塞阀,属于机械结构技术领域。
背景技术
目前,在出口发达国家用于水处理的阀门中,一般采用旋塞阀,通常是采用缩口设计,或即使采用全口设计,因阀芯在全开位置没有完全超过阀座孔流通区域,使阀芯的一部分阻挡阀座区域的流体流通,造成流体阻力增大,已不适应当前越来越高的节能要求。
发明内容
本实用新型的目的在于克服上述不足之处,从而提供一种流体(水)阻力小,节能环保的水处理用低阻节能旋塞阀。
按本实用新型提供的技术方案,水处理用低阻节能旋塞阀包括阀体、阀芯,所述阀芯安装在阀体的中腔内,特征是:所述阀芯上的阀芯头到阀芯转动中心距离大于等于阀体上阀座孔宽度的一半;阀体上阀座孔的流通面积大于等于阀体的公称流通面积;阀体的中腔直径等于进出口直径。所述阀体中腔与出口端底部相切。
本实用新型与已有技术相比具有以下优点:
本实用新型结构简单、紧凑、合理,流体(水)阻力小,节能环保。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
下面本实用新型将结合附图中的实施例作进一步描述:
如图1所示:本实用新型包括阀体1、阀芯2。阀芯2安装在阀体1的中腔内,阀芯2上的阀芯头2-1到阀芯转动中心的最小距离X大于等于阀体1上阀座孔宽度的一半Y (即X≥Y);阀体1上阀座孔的流通面积S1大于等于阀体的公称流通面积S2(即S1≥S2);阀体1的中腔直径B等于进出口直径A (公称直径) (即B=A),出口端底部1-2与阀体中腔1-1相切。
当阀芯2按箭头方向逆时针转动90°时(图示虚线位置)阀门处于全开状态,水从进口端3流经阀体阀座孔及中腔到出口端4流出,由于X≥Y、S1≥S2,所以阀芯在全开状态时水流通能力较大(即流阻较小),具有明显的节能效果;出口端底部1-2与阀体中腔1-1相切可以有效避免水及水中沉淀物在阀体内腔沉积造成的水质污染,此种无障碍设计使清洗阀门内腔更方便。
