Abstract

为了防止压控控体通气孔易堵塞的问题,本发明提供了一种气帽,气帽通气管下端设置螺纹,顶端与帽檐焊接在一起,通气管上部设置通气孔,通气孔外面设置通气孔挡板,该气帽有效地保证了通气的流畅,在检修时,不会因发体内气体温度过高而影响气帽的拆卸。

Description

一种气帽
技术领域
本发明涉及气液流通精密控制领域,具体地说是一种气帽。
背景技术
精密控制阀的控制有电控和压控之分,电控的精密度较高,但在一些易燃易爆领域不能使用电控,压控作为必要之选,压控的控体要与外界相通,以保证气压相等,压控控体的通气孔由于使用环境的影响极易堵塞而影响流量控制精密度。
发明内容
为了防止压控控体通气孔易堵塞的问题,本发明提供了一种气帽。
本发明是这样实现的:通气管下端设置螺纹,顶端与帽檐焊接在一起,通气管上部设置通气孔,通气孔外面设置通气孔挡板。
本发明的有益效果是:有效地保证了通气的流畅,在检修时,不会因发体内气体温度过高而影响气帽的拆卸。
附图说明
下面结合附图作进一步说明。
附图是本发明的结构示意图。
图中1、通气孔,2、通气孔挡板,3、帽檐,4、通气管,5、螺纹。
具体实施方式
如图所示,通气管4下端设置螺纹5,顶端与帽檐3焊接在一起,通气管4上部设置通气孔1,通气孔1外面设置通气孔挡板2。
使用时,阀体的通气由通气管4、通气孔1与外界相连通,通气孔挡板2可防止阀体内部过热气体对帽檐3的直吹,以致帽檐3过热或损坏。

Claims (1)

1.一种气帽,其特征在于,通气管下端设置螺纹,顶端与帽檐焊接在一起,通气管上部设置通气孔,通气孔外面设置通气孔挡板。
