Description

低功耗节能电动球阀
技术领域
本发明属于低功耗电动阀门技术领域，具体涉及一种低功耗节能电动球阀。
背景技术
电动阀门广泛用于市政供水、暖通空调、工业生产、农业灌溉等领域，随着科学技术自动化程度的提高，阀门的智能化控制需求越来越广。传统的电动阀门的机械构造不适用于低功耗直流微电压电源驱动，目前，现有使用的低功耗直流供电大口径阀门多采用先导式电动阀门，而由于先导式电动阀门主体结构多为截止式，所以造成了压力损失过大，流通能力差，结构复杂，使用场合单一等缺点，大大的降低了低功耗电动阀门的使用范围。
如何通过现有技术的改进，采用球阀导通技术，实现等面积直通介质，流通能力强，体积小，无压力损失的优点，是现有本行业技术人员亟待解决的技术问题。
发明内容
针对现有技术存在的问题，本发明的目的是提供一种低功耗节能电动球阀，其为解决其技术问题所采用的技术方案如下：一种低功耗节能电动球阀，包括一个固定式的阀体，阀体的下方装有球体芯，球体芯垂直安装，其底部和阀体通过轴承固定至一体，球体芯的顶部穿过阀帽并一直延伸至执行器控制盒内，球体芯和阀帽结合处固定有一个轴承和两个O型圈，所述的轴承设置在O型圈的下方，球体芯的顶部通过联轴器和电动执行器固定为一体；所述的执行器控制盒通过螺栓固定在阀帽顶部，阀帽通过螺栓和阀体固定为一体，阀帽和阀体结合处固定有一圈密封垫；阀体上，球体芯的右侧为出液口，球体芯的左侧为进液口，球体芯的左侧设置有活塞，活塞和球体芯之间镶嵌固定有四氟垫，活塞的左侧为弹簧，弹簧的左端卡装在进液口内侧，活塞和阀体的内壁结合处设置有两道O型圈。
所述的阀体上，阀体的内壁上和活塞接触部位打通有一个呼吸孔，所述的呼吸孔设置在两道O型圈之间并和阀体外部相通。
本发明的有益效果：本发明通过在阀座上镶嵌密封垫，并与球体芯侧边紧密相触，以管道介质本身压力和弹簧辅助推动活塞，保障其密封性能，活塞克服了原有固定式阀座与球体芯的挤压力矩，再结合球体芯顶部的电动执行器的驱动，带动球体芯转动，从而减轻了开关的扭矩，解决了大口径球阀的低功耗控制开关的难题，本发明充分利用了球体芯的优点，使本发明更具有等面积直通介质流通能力强，体积小，无压力损失的优点。
附图说明
本发明共有附图1幅，图1为本发明内部结构剖面示意图，下面结合附图对本发明进行进一步的说明。
附图中，1、阀体，2、阀帽，3、活塞，4、四氟垫，5、O型圈，6、呼吸孔，7、弹簧，8、球体芯，9、轴承，10、密封垫，11、执行器控制盒，12、电动执行器，13、联轴器，14、螺栓，15、出液口，16、进液口。
具体实施方式
一种低功耗节能电动球阀，包括一个固定式的阀体1，阀体1的下方装有球体芯8，球体芯8垂直安装，其底部和阀体1通过轴承9固定至一体，球体芯8的顶部穿过阀帽2并一直延伸至执行器控制盒11内，球体芯8和阀帽2结合处固定有一个轴承9和两个O型圈5，所述的轴承9设置在O型圈5的下方，球体芯8上下设置两个轴承，可有效保证电动执行器5驱动球体芯4转动时运行阻力小；球体芯8的顶部通过联轴器13和电动执行器12固定为一体；所述的执行器控制盒11通过螺栓14固定在阀帽2顶部；阀体1上，球体芯8的右侧15为出液口，球体芯8的左侧为进液口16，球体芯8的左侧设置有活塞3，活塞3和球体芯8之间镶嵌固定有四氟垫4，活塞3的左侧为弹簧7，弹簧7的左端卡装在进液口16内侧，活塞3和阀体1的内壁结合处设置有两道O型圈5。
本发明所述的阀体1组装时应注意，阀帽2通过螺栓14和阀体1安装至一体，为保证阀帽2和阀体1安装的密封性，阀帽2和阀体1之间设有一圈密封垫14；执行器控制盒11的底部通过螺栓14和阀帽2安装至一体。
所述的阀体1上，阀体的内壁上和活塞接触部位打通有一个呼吸孔6，所述的呼吸孔6设置在两道O型圈之间并和阀体1的外部相通，其作用是自动调节阀体1内外部压力，起到平衡阀体1内外部压力差的作用。
本发明运行时，本发明通过在活塞3与球体芯8之间镶嵌四氟垫4，并与球体芯8侧边紧密相触，以阀体1内部管道介质本身压力和弹簧7辅助推动活塞3，保障其密封性能，活塞3克服了原有固定式阀座与球体芯8的挤压力矩，从而减轻了开关的扭矩，再通过球体芯8上下两端的柄轴上各套装有一个轴承9，极大的促进了球体芯8转动时的顺畅性，有效的降低了球体芯8转动时的阻力，减少了电动执行器12的耗能，解决了大口径球阀低功耗控制开关的难题，本发明充分利用了球体芯的优点，使本发明更具有等面积直通介质流通能力强，体积小，无压力损失的优点，可在市政供水、暖通空调、工业生产、农业灌溉等领域广泛推广。
