Description

双口排气阀
技术领域
本实用新型主要涉及一种管道排气装置,尤其涉及一种双口排气阀。
背景技术
排气阀应用于独立采暖系统、集中供热系统、采暖锅炉、中央空调、地板采暖及太阳能采暖系统等管道排气。因为水中通常都溶有一定的空气,而且空气的溶解度随着温度的升高而减少,这样水在循环的过程中气体逐渐从水中分离出来,并逐渐聚在一起形成大的气泡甚至气柱,因为有水的补充,所以经常有气体产生。由于气体的产生,管道在运转时会出现水中断、停电、停泵管道及时出现负压会引起管道振动或破裂等现象。目前已有的排气阀,都是采用阀体、阀盖、浮球等组成的结构,浮球位于阀体内,无论是进气还是排气,浮球都是在阀体内做无规则运动,从而降低了排气阀的工作效率,从而影响了排气阀的正常工作,导致管道振动或破裂。
实用新型内容
本实用新型的目的是为了弥补已有技术的不足,提供了一种双口排气阀,解决了浮球的无规则运动降低排气阀的工作效率,阀体外杂物进入阀体内会影响浮球的运动等问题。
本实用新型是通过以下技术方案来实现的:
一种双口排气阀,包括有筒形阀体,所述阀体上端固定安装有阀盖,所述阀盖上设有出气口,所述出气口上方固定安装有阀帽,所述阀帽周边设有透气孔,且安装有防尘罩,且出气口下端安装有环形密封垫,所述阀体底端设有进流口接头,所述进流口接头内设有支承板,所述支承板上固定安装有竖向的导柱,所述导柱上竖向滑动安装有不锈钢浮球,所述导柱位于出气口的正下方。
其工作原理为:排气状态时,浮球由于顺水和重力作用沿筒形浮球托架运到到其底部,使出气口出现空隙,空气就通过此空隙由排气孔排出;空气排完时,水进入阀体内,浮球会随着水的浮力沿导柱上升,正好堵住出气口,停止排气,防止出现停电、停泵,管内水流空时随时出现负压等现象,且管内一旦出现负压时,此阀能迅速吸入空气,以保管道因负压所产生损坏,确保管道安全。
本实用新型的优点是:
本实用新型结构简单、安装使用方便,使浮球沿着导柱运动,避免了无规则运动,阻碍浮球的运动,影响了排气阀的工作效率,适用于输水的管道中。
附图说明
