Description

罐顶组件专用止回阀
技术领域
本实用新型涉及一种阀门,尤其是一种罐顶组件专用止回阀。
背景技术
目前反应装置的罐顶管道内经常出现反应后的反应物回流到反应之前的反应发生器内等情况,给使用者带来诸多不便。
发明内容
针对现有技术的不足,本实用新型提供了一种结构简单且能有效防止罐顶管道内反应物回流的罐顶组件专用止回阀。
为实现上述目的,本实用新型提供了一种罐顶组件专用止回阀,包括阀体、阀芯、阀盖、阀座,所述的阀芯设置在阀体内,阀芯与阀座之间设有复位弹簧,阀座与阀体之间通过阀盖连接。
本实用新型可进一步设置为所述的阀体与阀盖之间为螺纹连接,所述阀座的外圆周面上设有台阶面,阀盖的内圆周面上设有与阀座台阶面相抵配的肩阶。
本实用新型还可进一步设置为所述的阀芯与阀体之间设有密封圈,所述的阀座与阀体之间设有密封圈。
本实用新型的有益效果是:采用上述结构,在反应装置的罐顶管道内增设上述止回阀,可有效地防止罐顶管道内反应物回流等现象的发生。
附图说明
图1为本实用新型具体实施例的结构示意图;
图2为本实用新型的结构剖视图。
具体实施方式
如图1、2所示给出了一种罐顶组件专用止回阀1,包括阀体11、阀芯12、阀盖13、阀座14,所述的阀芯12设置在阀体11内,阀芯12与阀座14之间设有复位弹簧15,阀座14与阀体11之间通过阀盖13连接,所述的阀体11与阀盖13之间为螺纹连接,所述阀座14的外圆周面上设有台阶面141,阀盖13的内圆周面上设有与阀座14台阶面141相抵配的肩阶131,所述的阀芯12与阀体11之间设有密封圈16,所述的阀座14与阀体11之间也设有密封圈16。
在反应装置2的罐顶管道21内增设上述止回阀1,通过止回阀1的开闭可有效地防止罐顶管道21内反应物回流等现象的发生。
