Description

通气单向阀
技术领域
本实用新型涉及一种阀，特别涉及一种能让气体单向通过的阀。
背景技术
当向密闭容器注入液体时，需要解决以下问题：在液体注入时，能将容器内气体排出，当液体注满时，又能够自动单向截断，不使液体从排气口流出。而现有阀不能解决此问题，因此需要设计出一种新的通气单向阀。
实用新型内容
本实用新型为解决上述技术需求而提供一种通气单向阀，其结构简单、能够使气体单向通过。
本实用新型采用的技术方案为：通气单向阀，包括阀体、上衬套、下衬套、空心球、限位针，上衬套和下衬套分别装在阀体上下两端，限位针装在下衬套中，空心球装于阀体内腔中部，可在内腔中上下运动，上行至阀体内腔最高位置时密封上衬套出口，下行至限位针时由限位针支撑。
所述下衬套、下衬套和阀体之间用螺纹连接。
所述上衬套、下衬套和外部气、液管路之间用螺纹连接。
所述限位针装在上衬套的径向位置，并采用过盈连接。
本实用新型由于采用了上述通气单向阀，使用时其上衬套和外部密闭容器间用管路连接，当容器内注入液体时，容器中气体通过管路，进入下衬套、阀体，最后通过上衬套排出，由于空心球的重力及限位针的作用，空心球不会上下堵死上衬套或下衬套，因此气体会顺利排出；当容器内液体注满时，液体通过管路进入阀体，由于液体浮力作用，将空心球托起，此时，将出口衬套堵死，使得液体不会流出。因此本实用新型的结构简单，并且能够实现单向排气。
附图说明
图1是本实用新型实例的结构示意图。
具体实施方式
以下结合附图实施例对本实用新型作进一步描述。
如图1所示，通气单向阀，包括阀体3、下衬套1、上衬套2、不锈钢空心球4、限位针5。
下衬套1和上衬套2分别装在阀体3两端；不锈钢空心球4装于阀体3中间位置，可上下运动；限位针5装在上衬套2中，可限制不锈钢空心球向下运动。
所述下衬套1和外部密闭容器间用管路连接，当容器内注入液体时，容器中气体通过管路，进入下衬套1、阀体3，最后通过上衬套2排出，由于不锈钢空心球的重力及限位针的作用，不锈钢空心球不会下堵死下衬套1或上堵死上衬套2，因此气体会顺利排出；当容器内液体注满时，液体通过管路进入阀体3，由于液体浮力作用，将不锈钢空心球4托起，此时，不锈钢空心球将堵在出口衬套2的衬套口21上，出口衬套2被堵死，使得液体不会流出。
上述限位针装在衬套1的径向位置，并采用过盈配合，这样能更好地限位不锈钢空心球4。
上述下衬套1、衬套2和阀体3之间最好用螺纹连接，这样方便连接。
上述衬套1、衬套2和外部气、液管路之间用螺纹连接，这样方便连接。
