Description

一种轻型止回阀
技术领域
     本实用新型涉及一种止回阀,具体涉及的是一种轻型止回阀。 
背景技术
      目前市场的止回阀,由于本身结构中的连接方式是采用螺栓螺母连接的,摇臂和阀瓣是相互独立的,导致阀体的中心度偏高,整体的结构不紧凑,并且重量重,成本高。 
实用新型内容
本实用新型的目的为了提供一种结构简单,成本低,重量轻的轻型止回阀。 
为实现本实用新型的目的,本实用新型采用如下技术方案:一种轻型止回阀,包括阀体、阀盖、阀体中法兰,其特征在于:所述阀体里面装有阀瓣,所述的阀瓣上设有密封的O型圈,阀盖与阀体采用螺纹连接,阀盖上设有排污堵头,阀体中法兰和阀盖采用O型圈密封。 
本实用新型的有益效果:在阀体里面装有阀瓣,阀盖与阀体采用螺纹连接,缩小了中法兰的外径,使得整个阀门结构接凑,降低了成本,使得总体质量减轻。 
附图说明
     图1为实用新型的结构示意图。 
      阀体1,阀瓣2,密封O型圈3,阀盖4,阀体中法兰5,排污堵头6。 
具体实施方式
下面结合附图进一步说明: 
如图1所述,本实用新型包括包括阀体、阀盖、阀体中法兰,其特征在于:所述阀体里面装有阀瓣,所述的阀瓣上设有密封O型圈,阀盖与阀体采用螺纹连接,阀盖上设有排污堵头,阀体中法兰和阀盖采用O型圈密封。
本阀门通常是自动工作的,在一个方向流动的介质压力作用下,阀瓣打开;流体反方向流动时,由流体压力和阀瓣的自重作用于阀体密封面,从而切断介质流动。 
本实用新型的目的,特征及优点将结合实施例,参照附图作进一步的说明。通过实施例将有助于理解本实用新型,但不限制本实用新型的内容。本领域的普通技术人员能从本实用新型公开的内容直接导出或联想到的所有变形,均应认为是本实用新型的保护范围。
