Description

防磨损阀芯位移平稳型球阀
技术领域
本发明属于阀门领域，尤其涉及一种防磨损阀芯位移平稳型球阀。
背景技术
在流体输送管道中，球阀具有开通量大，启闭快的优点被广泛应用，球阀它具有旋转90度的动作，旋塞体（阀芯）为球体，有圆形通孔或通道通过其轴线。球阀在管路中主要用来做切断、分配和改变介质的流动方向，只需要用旋转90度的操作和很小的转动力矩就能关闭严密。球阀在使用过程中，由于频繁对阀芯进行旋转，阀芯和阀体的接触位置容易磨损，造成阀芯转动时左右晃动，产生振动，同时产生液体或者气体内泄漏。
现有技术中，CN203239985公开了一种真空球阀， 解决了因密封座磨损导致介质发生内泄等技术问题；在所述阀体的容腔内壁上设有U 形槽，在该U 形槽内设有与阀芯球面相贴合形成密封的弹性密封圈。该专利通过密封圈的弹性来弥补因密封圈的磨损所产生的间隙，从而有效防止真空阀门因密封座磨损而发生内泄，保证阀门的使用寿命。但是该专利并没有解决防阀芯和阀体磨损的问题，仅仅对产生磨损后进行了防内泄处理。
进一步地，现有技术中，球阀闭合时，由于阀门两侧压力的突然变化以及关阀的时间延时，容易产生回水，为了防止回水，通常需要安装止回阀配合球阀使用，增加成本，安装和维护麻烦。
发明内容
为了解决现有技术问题，本发明提供了一种防磨损阀芯位移平稳型球阀，能够防止阀芯和阀体磨损，阀芯位移平稳，不左右晃动，延长球阀使用寿命。
本发明采用的技术方案为：
一种防磨损阀芯位移平稳型球阀，包括阀体、阀杆和阀芯，阀体内设置有用于容置阀芯的容腔，阀芯设置在容腔内，阀杆穿过阀体与阀芯固定连接，阀芯与容腔的腔壁接触处设置有凹槽，容腔的腔壁上设置有凸面，阀芯转动时，凸面沿凹槽移动。扳动阀杆，阀芯随阀杆转动，凸面相对阀芯在凹槽内移动，凹槽限制了凸面沿凹槽轨道产生位移，不能够左右位移，阀芯位移平稳，同时，阀芯表面与容腔的腔壁不直接接触，防止阀芯磨损。
阀芯包括入水口和出水口，入水口和出水口之间设置有螺旋状管道。螺旋状管道能够将回水缓存在管道内，防止液体回流。
凹槽内设置有密封垫。密封垫为硅橡胶密封垫。硅橡胶密封垫耐磨损，且耐腐蚀。
凸面为陶瓷材质，陶瓷材质耐磨损且耐腐蚀。
凸面为圆弧状，圆弧状凸面与容腔接触面小，减小凸面与容腔的摩擦。
螺旋状管道的内径等于或者大于入水口的内径。使得螺旋状管道有足够的容量能够收容回流液体。
与现有技术相比，本发明有益效果包括：
本发明一种防磨损阀芯位移平稳型球阀，凹槽限制了凸面沿凹槽轨道产生位移，阀芯位移平稳，阀芯表面与容腔的腔壁不直接接触，防止阀芯磨损；
进一步地，阀芯的入水口和出水口之间设置有螺旋状管道。螺旋状管道能够将回水缓存在管道内，防止液体回流。
附图说明
图1为本发明一种防磨损阀芯位移平稳型球阀的结构示意图；
图2为本发明阀芯的左视图。
具体实施方式
下面结合附图对本发明作更进一步的说明。
如图1和图2所示，一种防磨损阀芯位移平稳型球阀，包括阀体1、阀杆2和阀芯3，阀体1内设置有用于容置阀芯3的容腔101，阀芯3设置在容腔101内，阀杆2穿过阀体1与阀芯3固定连接，阀芯3与容腔101的腔壁接触处设置有凹槽5，容腔101的腔壁上设置有凸面6，阀芯3转动时，凸面6沿凹槽5移动。扳动阀杆2，阀芯3随阀杆2转动，凸面6相对阀芯3在凹槽5内移动，凹槽5限制了凸面6沿凹槽轨道产生位移，不能够左右位移，阀芯位移平稳，同时，阀芯3表面与容腔101的腔壁不直接接触，防止阀芯磨损。
阀芯3包括入水口301和出水口302，入水口301和出水口302之间设置有螺旋状管道4。螺旋状管道能够将回水缓存在管道内，防止液体回流。
凹槽5内设置有密封垫。密封垫为硅橡胶密封垫。硅橡胶密封垫耐磨损，且耐腐蚀。
凸面6为陶瓷材质，陶瓷材质耐磨损且耐腐蚀。
凸面6为圆弧状，圆弧状凸面与容腔101接触面小，减小凸面与容腔的摩擦。
螺旋状管道4的内径等于或者大于入水口301的内径。使得螺旋状管道有足够的容量能够收容回流液体。
以上所述仅是本发明的优选实施方式，应当指出：对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
