Abstract

本实用新型提供了一种深冷止回阀,包括阀体、阀体内部设置有与其整体加工而成的凸台,铰接着摇杆的摇杆轴固定安装在凸台上,摇杆与摇杆轴之间设置有轴套,轴套固定安装在摇杆内圈,摇杆轴两个外露的扁平端头上设有通孔,紧固件穿过通孔将其与凸台固定连接,轴套和摇杆的两端与凸台抵接,进行轴向限位。本实用新型的有益效果是轴套和摇杆的两端与凸台抵接,进行轴向限位,有效的防止了摇杆的轴向窜动,保证了阀门的密封性能。

Description

一种深冷止回阀
所属技术领域
本实用新型涉及一种止回阀,特别涉及一种深冷工况下使用的止回阀。
背景技术
目前现有的止回阀中为了保证阀门的密封性,通常摒弃了利用支架来安装摇杆轴的结构,取而代之的是直接将摇杆轴与安装平台固定,零部件少,结构简单,且能很好的保证阀门的密封性。但是,这种结构的止回阀未采用摇杆端面与凸台轴向限位的结构,摇杆轴向窜动影响阀门的密封性能。
发明内容
为克服现有止回阀的上述缺陷,本实用新型提供一种摇杆处可以进行轴向限位的止回阀,保证了阀门的密封性能。
本实用新型解决其技术问题采用的技术方案是一种深冷止回阀,包括阀体、阀体内部设置有与其整体加工而成的凸台,铰接着摇杆的摇杆轴固定安装在凸台上,摇杆与摇杆轴之间设置有轴套,轴套固定安装在摇杆内圈,摇杆轴两个外露的扁平端头上设有通孔,紧固件穿过通孔将其与凸台固定连接,轴套和摇杆的两端与凸台抵接,进行轴向限位。 
本实用新型的有益效果是轴套和摇杆的两端与凸台抵接,进行轴向限位,有效的防止了摇杆的轴向窜动,保证了阀门的密封性能。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是实施例的结构示意图;
图2为图1所示的A-A剖视图;
图3为图2所示的B-B局部放大剖视图。
图1、2、3中:1.阀体;2.凸台;3.摇杆轴;4.摇杆;5.轴套。
具体实施方式
如图1、2、3所示,一种深冷止回阀,包括阀体1、阀体1内部设置有与其整体加工而成的凸台2,铰接着摇杆4的摇杆轴3固定安装在凸台2上,摇杆4与摇杆轴3之间设置有轴套5,轴套5固定安装在摇杆4内圈,摇杆轴3两个外露的扁平端头上设有通孔,紧固件穿过通孔将其与凸台2固定连接,轴套5和摇杆4的两端与凸台2抵接,进行轴向限位。
