Description

切换阀
技术领域
本发明涉及一种管路阀门，尤其涉及一种切换阀。
背景技术
切换阀用以控制液压系统中液体流动的通与断，其工作原理是利用阀芯和阀体的相对运动，使液体通路接通、关断或变换液流的方向。切换阀通常包括一阀体、收容于阀体内的一阀芯及控制阀心相对于阀体运动（旋转或移动）的一手柄，阀芯设有液体通道，通过手柄驱动阀芯运动，促使液体通道打开或关闭，实现了切换阀的功能。随着无限次、长时间的使用，阀心容易老化、磨损，影响了阀芯与阀体的密封效果，缩短了切换阀的使用寿命。
发明内容
本发明的目的在于提供了一种具有改善密封效果的切换阀。
为实现前述目的，本发明采用如下技术方案：一种切换阀，其包括一阀体、一阀芯及插入阀体内的一柱塞，所述阀芯定位于柱塞上，能够跟随柱塞上下移动或旋转，所述阀体设有空腔及与空腔连通的进液流道、排液流道，所述阀芯收容于腔体，所述阀芯包括一弧形壁、一内孔及一开口，所述弧形壁围设于内孔外侧，所述开口上下及侧向贯穿弧形壁，能够选择性与进液流道对齐和错开。
本发明切换阀的阀芯包括一弧形壁、一内孔及一开口，所述弧形壁围设于内孔外侧，所述开口上下及侧向贯穿弧形壁，能够选择性与进液流道对齐和错开，阀芯由于设置有开口，促使阀芯在空腔内保持膨胀的状态，紧贴于空腔内侧壁上，两者的间隙为零，改善了密封效果，对阀芯与阀体间的尺寸配合精度要求低，即使阀芯磨损，也能依靠张力紧贴于空腔内侧壁上，保证了切换阀的功能，有利于延长切换阀的使用寿命。
附图说明
图1为本发明切换阀的剖面示意图。
图2为本发明切换阀的阀芯与手柄配合的立体示意图。
图3为2的立体分解图。
图4为本发明切换阀的横截面视图。
具体实施方式
请参阅图1至图4所示，本发明切换阀10包括一阀体10、收容于阀体10内的一阀芯20、插入阀体10内的一柱塞30及将阀芯20定位于柱塞30上的定位轴40。
阀体10包括上阀体11及下阀体12，上阀体11支撑于下阀体12上，两者之间形成有一空腔13，上阀体11设有进液流道110及上排液流道111，下阀体12设有自上排液流道111向 下延伸的下排液流道120，进液流道110及上排液流道111分别与空腔13贯通。上排液流道111与下排液流道120组成排液流道。
阀芯20直立收容于空腔13内，并弹性抵压空腔13的内侧壁。阀芯20在上下方向上呈弧形，其包括一弧形壁21、一内孔22、一开口23及一对固定孔24，弧形壁21围设于内孔22外侧，开口23上下及侧向贯穿弧形壁21，使得阀芯20在圆周方向可以张合，固定孔24侧向贯穿弧形壁71，柱塞30向下插入于内孔22，弧形壁71的外侧面位于同一圆周面上，但内侧面在圆周方向上呈起伏状，增加了阀芯70的弹性张力。
阀芯20由于设置有开口23，促使阀芯20在空腔13内保持膨胀的状态，紧贴于空腔13内侧壁上，两者的间隙为零，改善了密封效果，对阀芯20与阀体10间的尺寸配合精度要求低，即使阀芯20磨损，也能依靠张力紧贴于空腔13内侧壁上，保证了切换阀100的功能，有利于延长切换阀100的使用寿命。
柱塞30底端向下插入空腔13，并且插入阀芯20的内孔22内。柱塞30设有侧向贯穿柱塞30的狭槽31，狭槽31还向下贯穿柱塞30。
定位轴40侧向穿过狭槽42，两末端固定于固定孔24，如此配置，柱塞40能够驱动阀芯70旋转。
本发明切换阀10工作时，首先，柱塞30带动阀芯20旋转一预定角度，使得开口23与进液流道110对齐，但与上排液流道111错开，液体自进液流道110流向开口23后，进入空腔13。然后，柱塞30带动阀芯20进一步旋转一预定角度，进液流道110被阀芯20的弧形壁21遮住，与开口23错开，开口23与上排液流道111对齐。接着，阀芯`20静止，柱塞30向下移动，压缩液体，促使液体自上排液流道111、下排液流道120压出阀体10。
尽管为示例目的，已经公开了本发明的优选实施方式，但是本领域的普通技术人员将意识到，在不脱离由所附的权利要求书公开的本发明的范围和精神的情况下，各种改进、增加以及取代是可能的。
