Abstract

本发明公开了一种进排气阀，其特征在于在阀体的上方通过螺栓安装带孔的阀盖，阀盖与阀体间设置大密封垫，所述阀体的内部设置浮体罩，在所述浮体罩内设置浮体，所述浮体下方设置衬垫与浮体罩接触，上方设置小密封垫与升降罩接触，升降罩安装在阀盖上阀杆套内的连杆上。通过以上设置，本发明即可进气又可排气，浮体位于浮体罩内，可以有效保护浮体，减少浮体受到水的冲撞，提高使用寿命。

Description

一种进排气阀
技术领域
本发明涉及一种阀门，具体说是一种即可进气又可排气的阀门。
背景技术
目前，输送水管道中时常出现气泡，气泡不能排出，会降低管道输送的效率，有时管道需要排干净液体，有需要有空气进入，而普通的阀门只能进气或排气。
发明内容
本发明的目的便是提供一种即可进气又可排气的阀门。
为了实现上述目的，本发明在阀体的上方通过螺栓安装带孔的阀盖，阀盖与阀体间设置大密封垫，所述阀体的内部设置浮体罩，在所述浮体罩内设置浮体，所述浮体下方设置衬垫与浮体罩接触，上方设置小密封垫与升降罩接触，升降罩安装在阀盖上阀杆套内的连杆上。
通过以上设置，本发明即可进气又可排气，浮体位于浮体罩内，可以有效保护浮体，减少浮体受到水的冲撞，提高使用寿命。
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、阀体，2、阀盖，3、大密封垫，4、浮体罩，5、浮体，6、衬垫，7、小密封垫，8、升降罩，9、阀杆套，10、连杆。
具体实施方式
如图1所示，本发明在阀体1的上方通过螺栓安装带孔的阀盖2，阀盖2与阀体1间设置大密封垫3，所述阀体1的内部设置浮体罩4，在所述浮体罩4内设置浮体5，所述浮体5下方设置衬垫6与浮体罩4接触，上方设置小密封垫7与升降罩8接触，升降罩8安装在阀盖2上阀杆套9内的连杆10上。通过以上设置，阀体1内流入水时，浮体5随着水位顶住浮体罩4上升，空气从阀盖2的孔排出，当水充满阀体1体腔时，浮体罩4在浮体5的作用下与大密封垫3紧密接触，实现密封；当阀体1内水排空时，浮体5随水位下降，使浮体罩4下降与大密封垫3分离，空气从阀盖2的孔进入，便于排空阀体1的水。
