Description

一种磁悬吸式气体流量调节阀口装置 技术领域
本发明涉及气体流量调节技术， 特別是一种用于调节气体流量大小 的磁悬吸式气体流量调节阀口裝置。 背景技术
在气体流量调节阀中， 特别是用于自动控制的气体流量调节阀， 其 阀口的结构及精度直接影响气体流量的调节特性、 精度及可靠性。 在现 有的自动恒溫燃气热水器中， 往往要求其燃气调节阀具备调节力小、 响 应快、 精度高、 一致性好、 可靠性高及能根据驱动元件的动作行程特性 去满足调节气量特性的要求， 同时还要制造方便、 成本低， 其中包括能 同时用作封闭。
在现有的燃气流量调节阀中， 使用滾珠式气体流量调节阀口裝置基 本可以达到调节力小、 响应快、 精度高、 一致性好、 可靠性高及能兼作 封闭的目的， 但由于其滚珠的圆形截面是固有的弧形， 而根据驱动元件 的动作行程特性需要满足调节气量特性的要求， 就只有改变导轨与滚珠 接触面的几何形状及小阀口、 导轨与滚珠的间隙来改变调节气体流量的 调节特性， 但在实际使用过程中， 仅靠改变导轨与滾珠接触面的几何形 状及小阀口、 导轨与滚珠的间隙来改变调节气体流量的调节特性， 往往 不容易满足使用要求， 有些情况下甚至非常难于加工， 如当需要调节特 性相对平緩时， 就有可能需要把导轨相对于滚珠接触面部分的几何形状 变成靠近小阀口的几何尺寸小， 而靠近大阀口的几何尺寸较大， 由于一 般的闼口几何尺寸都比较小， 用通常的压铸或注塑工艺是无法大批量制 造的。 此外当需要调节的气体流量较大时， 由于滾珠与大阀口之间要留 有足够的气体通道， 大阀口的直径及小阀口与大阀口的平面距离与小阀 口的半径即滾珠半径接近倍数关系， 而滚珠的重量则与其半径的增加成 立方比关系， 随着所需气体流量的增大到一定程度吋， 由于阀口装置体 积及滾珠重量的成倍增大， 将会使驱动元件的动作力必须随之增大。 发明的公开
本发明的目的在于提供一种磁悬吸式气体流量调节阀口装置， 它不 但具有调节力小、 响应快、 精度高、 一致性好、 可靠性高， 而且还能够 根据驱动元件的动作行程特性去满足阀体调节气量特性的要求， 并且制 造方便、 成本低及可同时作封闭用途。
本发明是这样实现的， 一种磁悬吸式气体流量调节阀口裝置， 包括 阀口本体、 阀片 ， 在阀口本体上设有同轴且相互平等放置的大、 小圆形 阀口， 在大阀口与小阀口之间的轴向截面内包络线是由至少一段任意形 状的曲线組成， 带永磁体的阀片置于大阀口外側， 在阀片与大、 小阀口 之间设有与帝永磁体的阀片相吸的导磁阀芯。 所述阀片表面或其内部沿 大、 小阀口轴线对称地裝有永磁体。 所述导磁阀芯为导磁滚珠或其截面 外轮廓由至少一段曲线組成的导磁旋转体。 所述导磁旋转体的旋转体可 以由非导磁材料制成， 在该旋转体内中轴线上裝有导磁材料。
该导磁滚珠或导磁旋转体可跟随阀片在小阀口上方中心位置上下移 动。
本发明当其通径较小， 可用普通的滚珠， 而其精度本身就比较高， 而小阀口与大阀口之间的轴向截面内包络线形状可以根据实际需要而定 且不会增加制造难度。 当其通径较大时， 采用截面外轮廓呈任意几何形 状的旋转体， 这样就可以不受滚珠初始中心位置必须在小阀口附近的限 制， 使得大阀口的直径及小阀口与大阀口的垂直距离不需要成倍增加， 多段曲线組成的由非导磁材料与导磁材料组成的导磁旋转体其重量及体 积也将大大減小， 所述的多段曲线之间呈圆滑过渡。 附图的简要说明 以下结合附图详细说明本发明的较佳实施例。 其中： 图 1是本发明在小流量情况下采用滚珠吋的结抅示意图；
图 2是本发明在小流量情况下采用滚珠吋的另一结抅示意图； 图 3是本发明在大流量情况下采用任意导磁旋转体的结抅示意图； 图 4是实施例 3阀片 1 向上移动一段距离后的结抅示意图。 实现本发明的最佳方式
实施例 1 , 本例是当气体调节流量比较小时， 导磁阀芯采用导磁滚 珠 4。
参见图 1 所示， 阀片 1 是用橡胶制成， 中心裝有永磁体 2， 在阀口 本体 3 上设有同轴且相互平行放置的大、 小圆形阀口 6、 5， 在大阀口 6 与小阀口 5 之间的轴向截面内包络线是由三段连续曲线抅成的， 阀片 1 置于大阀口 6外側。 当阀片 1 沿中心轴上下移动时， 导磁滚珠 4在永磁 体 2的作用下紧貼阀 1 表面且跟随其同步移动。 当阀片 1 紧贴大阀口 6 时， 处于封闭位置， 导磁滚珠 4的中心位置处理于小阀口 5的平面上方。 当阀片 1 向上移动时， 由于小阀口 5与大阀口 6之间的轴向截面内包络 线 7 是根据驱动阀片上、 下移动的动作行程特性 （突变或渐变） 和所需 气体流量特性要求而定的， 由多段曲线組成的， 当阀片 1 向上移动吋， 导磁滚珠 4也跟随向上移动， 在不同的位置上， 滚珠 4 的表面与内包络 线 7 之间的间隙就会产生相应的变化， 从而改变了气体等效通道而达到 调节气量的目的。 阀口本体 3采用注塑成型。
实施例 2
参见图 2所示， 本实施例中小阀口 5 与大阀口 6之间的轴向截面包 络线 7 是由三段半径为无限大的曲线即三段直线组成， 即由连接大阀口 的一段为平行于轴线的直线， 连接小阀口的一段朝大阀口倾斜的直线以 及连接上述两段直线的垂直于轴线的直线抅成， 以满足其中一种气体调节 特性的需要， 除此之外， 其结抅及工作原理与实施例 1 相同。 由此可见， 改变阀口包络线形状可以满足不同气体调节特性要求的需要。
实施例 3
参见图 3 所示， 本实施例是当气体调节流量较大吋， 导磁阀芯采用 其截面外轮廓由多段连续曲线组成的旋转体 9， 其中心裝有导磁体 8 。 其中旋转体 9用注塑成型。 由于采用了旋转体 9， 就不需要角例 1、 例 2 所示那样， 其大阀口 6 的直径必须大于滚珠 4 的直径接近一倍， 以便当 滚珠向上移动时， 气体有足够大的通道， 也不必使小阀口 5 与大阀口 6 的垂直距离必须大于导磁滚珠 4的半径， 使得阀口装置的体积大大缩小。 同时由于阀片 1 直径不需成倍加大， 也大大減少了封闭力。 此外， 由于 阀芯采用了塑料旋转体 9 与导磁体 8 的組合， 其重量也大为減少， 使得 驱动阔片的动作元件可采用与实施例 1 , 2 相接近的动作力， 就可调节 更大的流量。 本实施例的其他结构原理与实施例 1 、 2 相同， 图 4 表示 了本实施例中阀片 1 向上移动一段距离后的结抅， 其气体流动方向如图 4 中箭头所示。 由此可见， 改变导磁阀芯包络线形状也可以达到改变气 体调节特性的目的， 因而， 本发明可以通过同时或单独改变阀口包络线 形状或导磁阀芯包络线形状， 以满足不同气体调节特性的要求。 工业应用性
本发明与现有技术相比， 除具有所需调节力小、 响应快、 精度高、 一致性好、 可靠性高的优点外， 还具有可以任意决定气体流量特性， 制 造方便及当所需调节流量较大吋， 阀口装置的体积及重量仍然比较小。
