Abstract

本实用新型公开了一种角式球形止回阀，包括阀体、阀盖和球形阀芯，阀体上的进、出水口的轴心线呈垂直相交。本实用新型阀腔过流截面大，流体阻力小，不易产生气蚀，而且阀芯移动距离短，关闭时间短，不易产生破坏性水锤。止回阀可直接安装在管道弯曲处替代弯头使用，可以减少弯头使用数量，另外阀门结构简单，所用零件少，机械加工量小，制造成本低。

Description

一种角式球形止回阀
技术领域
本实用新型涉及一种球形止回阀，特别是用于自来水、污水处理管线中的球形止回阀。
背景技术
目前，通用的球形止回阀是直线形的，进、出水口在一条直线上，由于阀腔体积有限，导致流体阻力较大，而且阀芯启闭距离较大，以至阀门关闭时间较长，易容产生破坏性水锤。
发明内容
本实用新型的目的是提供一种角式球形止回阀，阀腔体积大，流体阻力小，关闭时间短，不易产生破坏性水锤。
本实用新型是这样实现的：它包括阀体、阀盖和球形阀芯，阀体上的进、出水口的轴心线呈垂直相交。由于进、出水口在空间上不在一条直线上，止回阀呈弯管状，阀腔不仅过流截面大，流体阻力小，而且阀芯移动距离短，关闭时间短，不易产生破坏性水锤。
为了防止阀芯堵塞出水口，阀体在出水口端内侧阀腔内设有限制阀芯进入出水口的挡块。
为了在关闭时阀芯能迅速轻回落至进水口，从而提高关闭速度，本实用新型的优先方案是阀盖内侧设有对阀芯上升高度限位的导向筋。这样阀芯可沿导向筋在阀腔内作上、下移动，可提高启闭速度。
本实用新型由于阀体上的出水口与进水口呈垂直相交，阀腔过流截面大，流体阻力小，不易产生气蚀，而且阀芯移动距离短，关闭时间短，不易产生破坏性水锤。止回阀可直接安装在管道弯曲处替代弯头使用，可以减少弯头使用数量，另外阀门结构简单，所用零件少，机械加工量小，制造成本低。
附图说明
图1是本实用新型结构示意图。
图2是图1中阀盖沿A-A线剖视图。
具体实施方式
如图1和图2所示，本实用新型由阀体3、阀盖5和球形阀芯2组成，阀体3和阀盖5之间有密封圈4，出水口8设在阀体3一侧，出水口8与进水口1的轴心线7、10呈垂直相交，阀体3在出水口8端内侧阀腔内设有限制阀芯2进入出水口的挡块9，阀盖5内侧设有对阀芯2上升高度限位的导向筋6。
图1所示阀门为关闭状态。进水时，阀芯2被水流托起并沿导向筋6下侧向出水口8一侧斜向上行至挡块9处，即图1中虚线所示位置。停止进水后，阀芯2随水流回落至进水口1上方，使阀门关闭。
