Abstract

本发明公开了一种新型止回阀，其特征在于，在阀球的表面包覆橡胶，阀球放置在阀体内，在阀座上设置挡块，阀座和接口管分别穿过密封圈套在阀体两端。通过以上设置，本发明不仅可以提高阀体的密封性，而且降低了阀球对阀座和阀体的冲击，减小了液体在阀内流动时的噪音；阀座与阀体为分离式设计，其中一个部件损坏时只需要更换损坏部件即可，有利于节约成本。

Description

一种新型止回阀
技术领域
本发明涉及一种阀门，具体说是一种用于防止液体回流的止回阀。
背景技术
目前用于防止液体回流的止回阀在工业上应用比较广泛，但普通的回止阀球阀、阀座和阀体多为金属，密封性较低，液体在阀内流动时容易带动阀球撞击阀座和阀体发出噪音，而且普通的回止阀阀座与阀体为一体设计不能分离，阀座和阀体其中一个部件损坏需要整体更换，不利于节约成本。
发明内容
本发明的目的便是提供一种便于更换密封性好噪音低的回止阀。
为了实现上述目的，本发明在阀球的表面包覆橡胶，阀球放置在阀体内，在阀座上设置挡块，阀座和接口管分别穿过密封圈套在阀体两端。
通过以上设置，本发明的阀球的表面包覆橡胶，不仅可以提高阀体的密封性，而且降低了阀球对阀座和阀体的冲击，减小了液体在阀内流动时的噪音；上述阀座与阀体为分离式设计，其中一个部件损坏时只需要更换损坏部件即可，有利于节约成本。
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、阀球，2、橡胶，3、阀体，4、阀座，5、挡块，6、接口管，7、密封圈。
具体实施方式
如图1所示，本发明在阀球1的表面包覆橡胶2，阀球1放置在阀体3内，在阀座4上设置挡块5，阀座4和接口管6分别穿过密封圈7套在阀体3两端。通过以上设置，当液体由左侧流向右侧时，由于挡块5的作用，使阀球1不能堵住阀座4，液体顺利从左侧流向右侧；当液体从右侧流向左侧时，液体带动阀球1向左侧流动，直至阀球1将接口管6完全堵住，此时液体停止流向左侧，进而实现了阀体3内液体的单向流动的目的。
