Description

一种柱塞阀
本实用新型涉及一种阀，确切地说是一种柱塞阀。
现有的阀种类很多，有轴向柱塞式增压注水泵，主要用于油田单井增压注水，该泵采用片式组合阀，泵头为单筒式结构，且左右三、三对称布置，但结构复杂，成本高；现有的柱塞阀，体积大且笨重，流体的流动阻力大，启闭操作费力，维修不方便。
本实用新型的目的在于：提供一种体积小，重量轻、流体的流动阻力小，启闭操作省力，维护方便的柱塞阀。
实现上述目的的技术解决方案是这样的，一种柱塞阀，由阀体(6)阀杆(5)柱塞和手轮(1)组成，其特征在于：柱塞由纵截面为浅“U”型的阀芯(9)、阀芯压盖(7)、密封圈(8)和摩擦环(10)组成，阀芯(9)下部的外侧设有凸缘，摩擦环(10)和密封圈(8)依次套设在阀芯(9)上，阀芯(9)通过阀芯压盖(7)及螺栓设于阀杆(5)的杆端。
阀体(6)的阀座上设有与阀芯(9)相对应的凸缘(11)。
本实用新型的优点是：
一、由于阀芯采用了浅“U”型结构，减小了柱塞的轴向尺寸，并减轻了柱塞阀的体积重量，减小了其内流体的流动阻力。
二、由于改进了上阀盖的结构形状，不仅使柱塞阀的密封更可靠，且使启闭操作更省力。
三、该柱塞阀结构设计合理，使用方便，在工作时即可维护。
图1：本实用新型结构示意图，
图2：图1中Ⅰ处的局部放大图。
下面通过附图，结合实施例对本实用新型作进一步的描述。
由图1、图2可见，该柱塞阀由阀体6、上阀盖4、阀杆5、阀芯9和手轮1组成。阀芯9的纵截面为浅“U”型，阀芯9下部的外侧有一圈凸缘，不锈钢磨擦环10和软填料密封圈8依次套装在阀芯9上；阀芯压盖7固定装于阀体5的杆端，阀芯9通过螺栓装于阀芯压盖7上。阀体6的阀座上也有一圈与阀芯9相对应的凸缘11。
使用时，上拧手轮1，阀杆5带动阀芯9上移，阀门开启，阀内的流体沿管路流动；下拧手轮1，阀芯9下移，当不锈钢磨擦环10底面与阀座上的凸缘11接触后，压缩软填料密封圈8，使其沿径向将阀座密闭，使阀门关闭，阻隔住阀内流体从一端流向另一端。
