Description

一种止回阀的密封结构
技术领域
本实用新型涉及阀类,具体属于一种止回阀的密封结构。
背景技术
目前,微阻缓闭止回阀结构形式各式各样,有启闭式止回阀的形式,也有外置缓冲缸形式,但都就需要一种液体才能够完成阀门关闭时的缓冲,消除破坏性水锤,以保障供水管道设施的运行安全可靠性。但往往由于液压管路的泄漏或阻塞,失去应有的功能。
实用新型内容
本实用新型的目的是提供一种止回阀的密封结构,结构设计合理,制作方便,增加了密封圈,密封效果提高。
本实用新型的技术方案如下:
一种止回阀的密封结构,包括有阀体,阀体的两端分别为进口端、出口端,阀体中固定有横置的阀杆,阀杆的一端固定于出口端,另一端滑动安装有阀芯,阀芯的后端与阀杆之间垫置有弹簧,阀芯与进口端之间设有密封圈。
本实用新型的进水端的压力大于弹簧的弹力时,阀口打开,出水端的压力小于弹簧的弹力时,阀口打开。结构设计合理,制作方便,增加了密封圈,密封效果提高。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种止回阀的密封结构,包括有阀体1,阀体1的两端分别为进口端2、出口端3,阀体中固定有横置的阀杆4,阀杆4的一端固定于出口端,另一端滑动安装有阀芯5,阀芯的后端与阀杆之间垫置有弹簧6,阀芯与进口端之间设有密封圈7。
