Abstract

本实用新型公开了一种流量恒定的止回阀，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，阀杆的后端设有台阶，阀体内设有与阀杆的台阶相配合的卡槽。本实用新型的阀体内设有与阀杆的台阶相配合的卡槽，保证了阀芯张开口度位移，结构设计合理，制作方便，具有限定最大流量的功能，密封效果提高。

Description

一种止回阀
技术领域
本实用新型涉及阀类，具体属于一种止回阀。
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。一般的止回阀没有限定流量的功能。
实用新型内容
本实用新型的目的是提供一种止回阀，结构设计合理，制作方便，具有限定最大流量的功能，密封效果提高。
本实用新型的技术方案如下：
一种流量恒定的止回阀，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，阀杆的后端设有台阶，阀体内设有与阀杆的台阶相配合的卡槽。
本实用新型的阀体内设有与阀杆的台阶相配合的卡槽，保证了阀芯张开口度位移，结构设计合理，制作方便，具有限定最大流量的功能，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，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，阀杆的后端设有台阶7，阀体内设有与阀杆的台阶相配合的卡槽8。

Claims (1)
