Description

一种防爆阻火呼吸阀
技术领域
本实用新型涉及一种油品储罐的阻火通风安全设施,尤其是一种防爆阻火呼吸阀。 
背景技术
防爆阻火呼吸阀工作原理是用弹簧限位阀板,由正负压力决定或呼或吸.呼吸阀应该具有泄放正压和负压两方面功能,具体:当容器承受正压时,呼吸阀打开呼出气体泄放正压;当容器承受负压时,阻火呼吸阀打开吸入气体泄放负压。由此保证压力在一定范围内,从而保证容器的安全。 
现有的防爆阻火呼吸阀的阀盘存在密闭性和灵活性无法兼顾的技术问题,大大影响了呼吸阀的使用性能。 
实用新型内容
本实用新型所要解决的技术问题在于提供了一种防爆阻火呼吸阀。 
为解决上述技术问题,本实用新型的技术方案是: 
一种防爆阻火呼吸阀,由阀盖、阀体和气流通道组成,所述阀盖和阀体螺栓固定连接,气流通道置于阀体内部中心轴线处,还包括正压阀盘和负压阀盘,所述正压阀盘通过阀盘运动控制装置垂直固定于气流通道上端,负压阀盘通过阀盘运动控制装置垂直固定于气流通道下端,所述正压阀盘和负压阀盘为圆形气囊。 
优选的,上述防爆阻火呼吸阀,所述正压阀盘和负压阀盘之间填充有氮气。 
优选的,上述防爆阻火呼吸阀,所述阀盖和阀体为铜合金或铝合金材质。 
本实用新型的有益效果是: 
上述防爆阻火呼吸阀由于将正压阀盘和负压阀盘设计为圆形气囊构造,增加了阀盘的润滑性,有效解决了现有呼吸阀密闭性和灵活 性无法兼顾的技术问题,且结构简单便于操作。 
附图说明
图1是本实用新型提供的一种防爆阻火呼吸阀的结构示意图。 
图中:1-阀盖  2-阀体  3-气流通道 
      4-正压阀盘  5-负压阀盘 
具体实施方式
为进一步说明本实用新型,现配合附图进行详细阐述: 
一种防爆阻火呼吸阀,由阀盖1、阀体2和气流通道3组成,所述阀盖1和阀体2螺栓固定连接,气流通道3置于阀体2内部中心轴线处,还包括正压阀盘4和负压阀盘5,所述正压阀盘4通过阀盘运动控制装置垂直固定于气流通道3上端,负压阀盘5通过阀盘运动控制装置垂直固定于气流通道3下端,所述正压阀盘4和负压阀盘5为圆形气囊,正压阀盘4和负压阀盘5之间填充有氮气,所述阀盖1和阀体2为铜合金或铝合金材质。 
以上所述仅是本实用新型的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本实用新型原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本实用新型的保护范围。
