Description

一种泄压式球面止回阀
技术领域
本发明涉及一种止回阀，更具体的说，他涉及一种泄压式球面止回阀。
背景技术
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开启压力过大造成阀芯碰撞损坏或弹簧失效，影响阀门的寿命和使用性能。
发明内容
为了解决以上的技术问题，本发明提供一种泄压式球面止回阀，对阀芯和弹簧等零件起保护作用，提高阀门的使用寿命和性能。
为实现上述目的，本发明所采用的技术方案如下：
一种泄压式球面止回阀，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，所述阀体内开有泄压通道，所述泄压通道为阶梯孔，阶梯孔内匹配有锥形阀芯，所述锥形阀芯右端预压有泄压弹簧，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梯同时与导流板接触导向，球面柱体阀芯与导流板之间装有压缩弹簧。
所述阀体与侧阀体之间采用螺栓和螺母连接。
所述垫圈材料为柔性石墨。
通过上述技术方案，本发明的有益效果是：
本发明利用泄压通道内锥形阀芯的开启，来避免球面柱体阀芯的损坏或弹簧的失效，密封性能好，阀门寿命长，可广泛应用于冷水、热水、工业及生活污水等管网的水泵出口。
附图说明
图1为本发明的泄压式球面止回阀的结构示意图。
图中所示附图标记为：1-阀体；2-球面柱体阀芯；3-弹簧；4-螺栓；5- 螺母；6-导流板；7-侧阀体；8-垫片；11-球面柱体阀芯一级阶梯；12-球面柱体阀芯三级阶梯；13-导向杆；14-泄压弹簧；15-泄压通道；16-锥形阀芯；17-阶梯孔。
具体实施方式
下面结合附图对本发明实施例作进一步说明：
如图1所示，本发明提供了一种泄压式球面止回阀，包括侧阀体7，侧阀体7左端与阀体1右端通过螺栓4和螺母5连接，方便阀门的安装、调试，维修；侧阀体7左端设置有导流板6，导流板6与阀体1和侧阀体7之间分别装有垫片8，且垫片7为柔性石墨材料，增强阀门的密封性能；导流板6内装有球面柱体阀芯2，球面柱体阀芯2与阀体1中部形成密封面，球面柱体阀芯2上设置有导向杆13，且导向杆13成三级阶梯状，球面柱体阀芯一级阶梯11和球面柱体阀芯三级阶梯12同时与导流板6接触导向，保证密封不发生错位；球面柱体阀芯2与导流板6之间装有压缩弹簧3，利用弹簧3弹压球面柱体阀芯2，增强阀门的密封性能；阀体1内开有泄压通道14，泄压通道14为阶梯孔17，阶梯孔17内匹配有锥形阀芯16，锥形阀芯16右端预压有泄压弹簧15，当开启压力过大时，锥形阀芯16向右移动，起到保护阀门的作用。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而这些属于本发明的实质精神所引伸出的显而易见的变化或变动仍属于本发明的保护范围。
