Description

活塞式单向阀
技术领域
本实用新型涉及一种管道控制设备，更具体地说，本实用新型涉及一种活塞式单向阀。
背景技术
单向阀是制冷设备中不可或缺的重要配套部件，安装在制冷设备压缩机的排气口处，用于防止停机时压缩机反转，或防止制冷剂从运转的压缩机流到未运转的压缩机中。工作时，活塞在压差的作用下进行往复运动，达到关闭或开启单向阀的目的。由于现有单向阀定位依靠活塞相对阀座的往复滑动进行，介质中的杂质容易堵塞活塞与阀座内壁之间的空隙，进而导致单向阀多次使用后，活塞会出现倾斜，与阀座不对中，降低了单向阀的可靠性。此外，制冷设备在运行中会因压力脉冲产生的震动，既造成制冷设备运行时的噪声，又会对制冷设备造成机械磨损，影响设备的使用寿命。
发明内容
本实用新型发明的目的是克服现有技术的不足，提供一种减震降噪、延长制冷设备使用寿命的活塞式单向阀。
本实用新型发明的目的是通过以下技术方案实现的：
一种活塞式单向阀，所述的单向阀由阀体、阀盖和活塞连接构成。所述阀体内设有圆柱形阀座，所述阀座的一侧连通介质进口，其底部与阀体连成一体，阀座的外侧与阀体形成空腔，且与介质出口连通，其上部开口与活塞配套，所述的活塞包括活塞头和活塞杆，所述的活塞头通过密封垫和阀座的开口密封闭合或开启，所述的阀盖中心向外突出一圆柱形凸块，其内设有圆柱形活塞杆套，该活塞杆套与活塞杆相配套，活塞杆套一端设有连接阀盖的弹簧座，弹簧座上套有弹簧，弹簧的另一端套在活塞杆上，所述阀盖的端口水平连接环形裙边，该裙边的内圆与活塞头的外圆及密封垫紧密配合，在阀盖内形成一个密闭的空腔。
本实用新型发明的目的还可以通过以下技术方案实现的：
所述阀座开口的端面为圆弧形。所述活塞头的中心设有螺孔及配套的螺栓和垫片，通过拧紧螺栓，将垫片和密封垫压紧。所述阀体的底部中心设有安装螺孔。所述活塞杆端面的中心设有圆孔。所述的阀盖通过螺栓固定连接阀体。
与现有技术相比，本实用新型具有以下有益效果：
1.降低制冷设备运行时的噪音；
2.提高制冷设备的使用寿命。
附图说明
图1为活塞式单向阀剖面图；
   图2为活塞式单向阀俯视图；
   图3为活塞式单向阀侧视图。
图中：阀体1、阀盖2、阀座3、进口4、空腔5-1、5-2、5-3、出口6、活塞头7、活塞杆8、密封垫9、活塞杆套10、弹簧座11、弹簧12、环形裙边13、螺栓14-1、14-2、垫片15、安装螺孔16、圆孔17。
具体实施方式
下面将结合附图对本实用新型的实质性内容作进一步详细描述：
如图1至图3所示：一种活塞式单向阀，由阀体1通过螺栓14-2固定连接阀盖2，活塞置于阀体1的空腔内。阀体1内设有圆柱形阀座3，阀座3的一侧连通介质进口4，其底部与阀体1连成一体，阀座3的外侧与阀体1形成空腔，且与介质出口6连通，其上部开口与活塞配套，活塞包括活塞头7和活塞杆8，通过螺栓14-1将垫片15和密封垫9固定在活塞头7端面的中心，密封垫9和阀座3的开口密封闭合或开启，阀座3开口的端面为圆弧形，便于密封垫9压实阀座3开口。阀盖2中心向外突出一圆柱形凸块，其内设有圆柱形活塞杆套10，该活塞杆套10与活塞杆8相配套，活塞杆8端面的中心设有圆孔17，有利紧密配合活塞杆套10及减轻活塞杆8的分量。活塞杆套10一端设有连接阀盖2的弹簧座11，弹簧座11上套有弹簧12，弹簧12的另一端套在活塞杆8上。阀盖2的端口水平连接环形裙边13，该裙边13的内圆与活塞头7的外圆及密封垫9紧密配合时，在阀盖2内形成一个密闭的空腔。阀体1的底部中心设有安装螺孔16，用以将本实用新型固定在制冷设备上。
