一种导向式球面止回阀
本技术涉及一种止回阀,更具体的说,他涉及一种导向式球面止回阀。
技术介绍
止回阀是流体控制工程的基本元件,它通过制止流体逆流,起到确定流体流动方向、保护其它流体机械以及管线安全的作用,其广泛用于石油、冶金、化工、电力、建筑、热力、水处理等行业。普通球面止回阀由于没有导向机构或者导向机构和其它结构的接触处只有一处,以致阀芯或阀瓣的对中性能很差,造成阀芯或阀瓣与阀体不能很好的实现密封,影响阀门的使用性能。
技术实现思路
为了解决以上的技术问题,本技术提供一种导向式球面止回阀,利用球面柱体阀芯与导流板在两处接触导向,同时弹簧弹压球面柱体阀芯,从而加强对中性,结构设计合理,密封性能好。为实现上述目的,本技术所采用的技术方案如下:一种导向式球面止回阀,包括阀体、球面柱体阀芯、弹簧、导流板、侧阀体、垫片,其特征在于:所述侧阀体左端与阀体右端连接,侧阀体左端设置有导流板,所述导流板与阀体和侧阀体之间分别装有垫片,导流板内装有球面柱体阀芯,所述球面柱体阀芯与阀体中部形成密封面,球面柱体阀芯上设置有导向杆,且导向杆成三级阶梯状,球面柱体阀芯一级阶梯和球面柱体阀芯三级阶 ...
