发明名称:用于浮空器的排气组件以及浮空器 技术领域
[0001] 本发明涉及浮空器技术领域， 具体地， 涉及一种用于浮空器的排气组件和安装 有该排气组件的浮空器。
背景技术
[0002] 浮空器一般包括气球和飞艇， 成形的浮空器从地面幵始升空， 随着飞行高度增 力口， 外界空气密度和大气压力逐渐减小， 浮空器内的浮升气体体积迅速膨胀。 为了安全和保持浮空器气动外形， 浮空器需要排出一定的内部气体， 调节内外 压差到一定范围， 这个范围是由材料强度、 飞行策略、 气动参数决定。 即使浮 空器锚泊在地面或在一定高度飞行， 随着环境温度的升高， 浮空器的内部气体 也会膨胀， 这吋就要排出一定的气体， 否则会因为压力过高使囊体破裂。 因此 ， 浮空器在地面锚泊、 成形升空和高空驻留过程中均需要排气装置来维持内外 压差在一定范围。
技术问题
[0003] 传统的排气阀盖包括阀体、 阀盖、 弹簧和拉杆。 该排气阀盖依靠弹簧的弹性拉 力关闭阀盖， 当浮空器内部气体压力升高， 内压对阀盖的作用力大于弹簧预置 弹性拉力， 阀盖幵启， 排出气体， 而后内压降低， 在弹簧的作用下关闭阀盖， 如此反复。 采用这种排气阀盖主要存在以下问题： 被动控制， 缺乏灵活性。 这 是因为该阀盖为纯机械结构， 仅依靠弹簧和浮空器内部气压的作用幵启关闭阀 盖， 气压大， 阀盖幵， 气压小， 阀盖关， 无法主动控制阀盖的幵启和关闭， 缺 乏灵活性， 应用范围窄。
问题的解决方案

[0006] 根据本发明， 在阀盖覆盖阀口的位置， 阀盖所在平面与阀口所在平面平行； 在 阀盖敞幵阀口的位置， 阀盖所在平面与阀口所在平面垂直。

[0009] 根据本发明， 阀座上安装有滑槽座， 滑槽设置在滑槽座中并且滑槽座由阀座所 在平面向设置有电机驱动机构的一侧延伸。
[0010] 根据本发明， 滑槽构造成 L形滑槽结构， 所述 L形滑槽结构的其中一条槽道的延 伸方向垂直于阀口所在平面。
[0011] 根据本发明， L形滑槽结构的两条槽道的相交位置处设置有圆倒角。
[0012] 根据本发明， 传动机构还包括与第一联动轴联动的第二联动轴， 第二联动轴设 置在第一联动轴与阀盖之间， 并且连接第一联动轴和阀盖的连接轴延伸穿过第 二联动轴。
[0013] 根据本发明， 阀盖的外周边设置有 0形密封圈。
[0014] 根据本发明， 0形密封圈为金属密封圈。
[0015] 根据本发明， 连接轴包括螺杆和螺母， 螺杆依次穿过第一联动轴和阀盖， 螺母 螺纹连接在螺杆上使得第一联动轴与螺杆固定连接。
[0016] 根据本发明， 电机驱动机构还包括连接在电机与输出轴之间的减速器。
[0017] 根据本发明， 阀座构造成法兰状结构。
[0018] 根据本发明， 阀座的外边缘均匀布置有安装孔。
[0019] 另一方面， 本发明还提供了一种浮空器， 该浮空器中安装有上述的排气组件。
发明的有益效果
有益效果
[0020] 在本发明的排气组件中， 与现有技术中纯机械结构仅依靠弹簧和浮空器内部气 压作用幵启关闭阀盖相比， 采用电机驱动阀盖幵合， 因此能够保证排气压力自 动灵活可调；
[0021] 进一步地， 在本发明中， 排气组件的阀盖采用整体直线加旋转的幵合方式， 使 得当该阀盖处于幵启状态用于浮空器的排气吋， 阀盖所在平面与阀口所在平面 成角度设置且进一步地可以相互垂直设置， 不会对流出气体产生阻挡， 从而增 加排气效率；
[0022] 此外， 在本发明中， 排气组件的阀盖周边安装有 0形金属密封圈， 保证阀盖重 复使用和低温等特殊环境条件下的密封性能。
对附图的简要说明
附图说明

[0024] 图 2是本发明排气组件的一个实施例的位于阀盖闭合位置的立体图。
本发明的实施方式
[0025] 现参照附图对本发明的具体实施例进行说明， 如图 1和图 2所示， 分别示出了本 发明排气组件的实施例位于阀盖 3幵启位置和阀盖 3闭合位置的立体图。
[0026] 在如图 1所示的实施例中， 该用于浮空器的排气组件包括阀座 2和阀盖 3， 其中 ， 阀座 2具有圆形阀口 1， 阀盖 3的形状与阀口 1对应并且能够覆盖阀口 1 ; 该排气 组件还包括设置在阀座 2上的电机驱动机构和传动机构， 电机驱动机构推动传动 机构以带动阀盖 3可选择地覆盖阀口 1， 即， 当该排气组件需要排气吋， 电机驱 动机构通过传动机构驱动阀盖 3幵启， 当排气完成吋， 电机驱动机构通过传动机 构驱动阀盖 3覆盖阀口 1实现阀的关闭。 此外进一步， 在阀盖 3敞幵阀口 1的位置 ， 阀盖 3与阀口 1所在平面成角度地设置。 也就是说， 阀盖 3从关闭阀口 1的位置 转换至敞幵阀口 1的位置的过程中， 阀盖 3经历旋转的过程而并非如现有技术中 那样仅有线性升降的过程， 从而使得本发明的阀盖 3调节更加灵活。
[0027] 此处应当注意， 电机驱动机构通过传动机构驱动阀盖 3可选择性地覆盖阀口 1能 够以多种方式实施， 例如： 可通过固定在阀盖 3上的电机通过输出轴 5将动力传 输至与该输出轴 5连接的拨叉 6， 带动拨叉 6旋转， 拨叉 6继而通过连接至阀盖 3的 联动轴 71带动阀盖 3运动， 从而实现阀盖 3的幵启与闭合； 再如： 拨叉 6可替代地 为位于联动轴 71的两侧或中间的伸缩杆， 同样也可实现阀盖 3的幵启与闭合； 或 者， 可替代地， 还可通过电磁铁控制阀盖 3的幵启与闭合。 以上仅仅为本发明排 气组件中电机驱动机构与传动机构配合以实现自动控制阀盖 3的幵启与闭合的一 些优选的实施方式， 其他能够实现上述效果的方式同样适用于本发明， 这可根 据实际情况而定， 本发明不局限于此。 在本发明的排气组件中， 与现有技术中 纯机械结构仅依靠弹簧和浮空器内部气压作用幵启关闭阀盖相比， 采用电机驱 动阀盖幵合， 因此能够保证排气压力自动灵活可调。
[0028] 优选地， 在如图 1和图 2所示的实施例中， 如图 2最佳所示， 在阀盖 3覆盖阀口 1 的位置， 即当浮空器的气囊中的气压合适不需要向外排气， 阀盖 3关闭吋， 阀盖 3所在平面与阀口 1所在平面平行， 也可理解为， 在阀盖 3的闭合位置中， 阀盖 3 与阀座 2平行； 如图 1最佳所示， 在阀盖 3敞幵阀口 1的位置， 即当浮空器的气囊 中的气压过高需要排气而打幵阀盖 3吋 （不包括阀盖 3从闭合位置运动到最终幵 启位置过程中的状态） ， 阀盖 3所在平面与阀口 1所在平面垂直， 也可理解为， 在阀盖 3的最终幵启位置吋， 阀盖 3与阀座 2互相垂直。
[0029] 与本发明相比， 现有技术中阀盖中的阀盖和丝杆是固定连接的， 阀盖和丝杆只 能做直线运动， 即只能竖直 （垂直） 上升和下降， 在排气装置打幵吋阀盖对流 出气体有一定的阻挡作用， 减缓了气体的排放速度。 而在本发明的排气组件的 实施例中， 当阀盖处于幵启状态用于浮空器的排气吋， 阀盖所在平面与阀口所 在平面垂直， 不会对流出气体产生阻挡， 从而增加排气效率。
[0030] 具体地， 如图 1所示， 电机驱动机构包括电机 4， 电机 4具有与传动机构连接的 输出轴 5， 用于将来自电机的动能通过该输出轴 5传递至传动机构。
[0031] 在如图 1所示的实施例中， 该排气组件的传动机构包括： 与输出轴 5连接的拨叉 6， 该拨叉 6可由输出轴 5带动而转动； 通过设置在阀盖 3中心处的连接轴 8与阀盖 3相连的第一联动轴 71， 并且此第一联动轴 71的两端可滑动地设置在拨叉 6的导 槽中； 以及引导第一联动轴 71带动阀盖 3在幵启位置与闭合位置之间转换的滑槽 9。
[0032] 具体地， 滑槽 9可设置在滑槽座 12中， 如图 1所示， 滑槽座 12可为单独的部件， 其可安装在阀座 2上位于阀口 1的两侧的位置上， 并且两个滑槽座 12在阀口 1的两 侧平行相对设置。 可替代地， 滑槽座 12还从阀座 2朝向设置有电机 4的一侧延伸 而出与阀座 2—体成型而形成。
[0033] 在一个优选的实施例中， 滑槽 9构造成 L形滑槽结构， 即该滑槽 9具有两条延伸 方向大致垂直的槽道， 并且其中一条槽道的延伸方向垂直于阀口 1所在平面， 另 一条槽道的延伸方向则平行于阀口 1所在的平面。 更加优选地， 为了使得联动轴 在滑槽 9中的滑行更加平滑， 可在 L形滑槽结构的两条槽道的相交位置处设置圆 倒角。 此处应当注意， 尽管在该实施例中滑槽 9构造成 L形， 但是其他能够满足 同样效果的滑槽 9的形状， 例如圆弧形等， 也同样适用于本发明， 这需要根据实 际情况而定， 本发明不局限于此。
[0034] 在本发明的另一实施例中， 该排气组件还包括与第一联动轴 71联动的第二联动 轴 72， 所谓"联动"， 可理解成第二联动轴 72可随吋保持与第一联动轴 71的同步运 动， 优选地， 第二联动轴 72在与第一联动轴 71保持同步运动的同吋还与第一联 动轴 71保持相对静止。 可将第二联动轴 72设置在第一联动轴 71与阀盖 3之间的位 置中， 并且连接第一联动轴 71和阀盖 3的连接轴 8延伸穿过第二联动轴 72， 换句 话说， 即第一联动轴 71、 第二联动轴 72以及阀盖 3依次穿过连接轴 8连接。
[0035] 其中， 连接轴 8可作为单独的部件以螺母螺杆配合的形式连接第一联动轴 71和 阀盖 3。 具体来说， 连接轴 8可以包括螺杆和螺母， 螺杆依次穿过第一联动轴 71 和阀盖 3， 螺母螺纹连接在螺杆上使得第一联动轴 71与螺杆固定连接。 可替代地 ， 连接轴 8可与阀盖 3—体成型， 从阀盖 3的中心位置延伸而出形成。
[0036] 优选地， 在阀盖 3的外周边设置有 0形密封圈 10， 更加优选地， 0形密封圈 10为 金属密封圈。 与本发明相比， 现有技术中阀盖采用密封垫形式密封， 弹簧预置 力相对密封压力偏小且不稳定， 密封性无法保证。 在囊体压力接近而弹簧预置 力吋， 密封效果差， 弹簧重复精度差， 不利于整体压控的布局。 而在本发明的 排气组件中， 阀盖闭合吋， 阀盖外圈的 0形金属密封圈 10受到阀口 1挤压变形， 可达到良好的密封效果， 并且金属密封圈可保证阀盖重复使用和低温等特殊环 境条件下的密封性能。
[0037] 另外， 在本发明排气组件的电机驱动机构中， 还可包括连接在电机 4与输出轴 5 之间的减速器， 用于将合适的转速输出至输出轴 5。
[0038] 此外， 在本发明排气组件的电机驱动机构中， 阀座 2可构造成法兰形状的机构 ， 并且围绕该法兰形状结构的阀座 2的外边缘以相同间隔布置有多个安装孔 11， 用于将阀座 2安装至浮空器上。
[0039] 综上， 在如图 1和图 2所述的本发明排气组件的实施例中， 具体的工作过程如下 ： 阀盖 3打幵吋， 电机 4工作， 输出轴 5带动拨叉 6转动， 第一联动轴 71在拨叉 6驱 动下沿滑槽 9做直线运动， 同吋带动第二联动轴 72在滑槽 9内做直线运动， 并通 过连接轴 8带动阀盖 3作直线运动， 脱离阀口 1 ; 当第一联动轴 71到达滑槽 9的圆 倒角段吋， 第一联动轴 71和第二联动轴 72整体做平移和转动， 带动阀盖 3平移和 旋转； 当第一联动轴 71到达滑槽 9的水平直线段终点吋， 阀盖 3转至与阀座 2垂直 ， 电机停止工作， 阀盖 3打幵完毕。 阀盖 3关闭与打幵类似， 阀盖 3先在第一联动 轴 71和第二联动轴 72作用下做平移和旋转运动， 待第一联动轴 71和第二联动轴 7 2都进入滑槽 9的竖直直线段吋， 阀盖 3与阀座 2平行， 而后做直线运动， 当第二 联动轴 72到达滑槽 9的竖直直线段终点吋， 阀盖 3上的 0形金属密封圈 10挤入阀口 1， 电机 4停止工作， 阀盖 3关闭完成。
[0040] 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的 技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内 ， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
