Abstract

本发明公开了一种立式止回阀，其特征在于，在阀体的内部安装阀座，阀盖通过螺栓螺母安装在阀体上，滑杆安装在阀盖的滑道内，滑杆底部联接阀瓣，在阀瓣的底部安装密封圈与阀座相对应。通过以上设置，本发明的阀瓣在关闭时，阀座的外沿可完全与密封圈接触，保证了阀瓣关闭时的密封性，有效地防止了阀体内液体的回流。

Description

一种立式止回阀
技术领域
本发明涉及一种阀门，具体说是一种用于防止管道液体回流的立式止回阀。
背景技术
目前常用的立式止回阀，阀瓣与阀座直接接触，或者阀瓣与阀座间的密封结构较窄，使得阀体中阀瓣关闭时仍有少量液体回流。
发明内容
本发明的目的便是提供一种解决上述问题的立式止回阀
为了实现上述目的，本发明在阀体的内部安装阀座，阀盖通过螺栓螺母安装在阀体上，滑杆安装在阀盖的滑道内，滑杆底部联接阀瓣，在阀瓣的底部安装密封圈与阀座相对应。
通过以上设置，本发明的阀瓣在关闭时，阀座的外沿可完全与密封圈接触，保证了阀瓣关闭时的密封性，有效地防止了阀体内液体的回流。
附图说明
现结合附图对本发明做进一步说明。
图1为本发明的结构示意图。
图中：1、阀体，2、阀座，3、阀盖，4、滑杆，5、阀瓣，6、密封圈。
具体实施方式
如图1所示，本发明在阀体1的内部安装阀座2，阀盖3通过螺栓螺母安装在阀体1上，滑杆4安装在阀盖3的滑道内，滑杆4底部联接阀瓣5，在阀瓣5的底部安装密封圈6与阀座2相对应。通过以上设置，在一个方向流动的液体压力作用下，阀瓣5打开；流体反方向流动时，由流体压力和阀瓣5的自身重力将阀瓣5作用于阀座2，从而切断流动。
