发明内容
本发明的目的是提供一种可自由调节空气进气量的阀门，克服了现有比例混合器不能对空气进气量全开到全关调节的不足，可以对空气进气量实行定量控制，大大提高燃气发动机的适用范围，可以满足燃气发动机在各种条件下的使用要求。
为实现上述目的，本发明提供一种可自由调节空气进气量的阀门，包括两端分别与比例混合器与空气滤清器密封连接的连接管，所述连接管的内部是空气通道，所述空气通道内设置有挡板和连接轴，所述连接轴的两端贯穿安装在连接管壁上，所述挡板安装在连接轴上，所述连接管的外部设有可使挡板在0°-90°范围内旋转以关闭和打开该空气通道的控制装置，所述控制装置连接至连接轴的一端。
作为本发明的进一步改进，所述控制装置为手动操作旋钮。
作为本发明的更进一步改进，所述手动操作旋钮呈半圆状，所述半圆状旋钮上设有与其弧度相适应的圆弧形凹槽，所述圆弧形凹槽内设有角度刻度线。
作为本发明的更进一步改进，所述圆弧形凹槽内还设有手动拨块。
作为本发明的更进一步改进，所述手动操作旋钮上还设有可将旋转后的手动操作旋钮固定的固定装置。
作为本发明的更进一步改进，所述固定装置为螺栓。
作为本发明的进一步改进，所述控制装置为步进电机，所述步进电机的输出轴通过传动机构连接连接轴。
作为本发明的更进一步改进，所述传动机构为联轴器。
作为本发明的更进一步改进，所述传动机构为蜗轮蜗杆机构，所述蜗轮蜗杆机构的蜗轮连接连接轴，所述蜗轮蜗杆机构的蜗杆连接步进电机。
作为本发明的更进一步改进，所述挡板的外径与连接管的内径相同。
与现有技术相比，本发明的可自由调节空气进气量的阀门采用控制装置和连接轴可以调节挡板的角度，改变空气通道的大小，从而可对空气进气量实行定量控制，大大提高燃气发动机的适用范围，可以满足燃气发动机在各种条件下的使用要求；结构简单，制造成本低。
通过以下的描述并结合附图，本发明将变得更加清晰，这些附图用于解释本发明的实施例。
附图说明
图1为实施例一的阀门的示意图。
图2为实施例一的阀门另一角度的示意图。
图3为实施例二的阀门的示意图。
具体实施方式
现在参考附图描述本发明的实施例，附图中类似的元件标号代表类似的元件。
实施例一
请参考图1和图2，所述的可自由调节空气进气量的阀门包括连接管1，所述连接管的两端分别与比例混合器与空气滤清器密封连接，从而使得阀门整体密封，无漏气现象。所述连接管1的内部是空气通道11，所述空气通道11内设置有挡板2和连接轴3，所述连接轴3的两端贯穿安装在连接管1的管壁上，所述挡板2安装在连接轴3上，所述挡板2的外径与连接管1的内径相同，从而能无缝隙阻隔空气进气。所述连接管1的外部设有手动操作旋钮4，所述手动操作旋钮4连接至连接轴3的一端，其通过连接轴3联动挡板2，以使挡板在0°-90°范围内旋转以关闭和打开该空气通道11。
具体而言，所述手动操作旋钮4呈半圆状，所述半圆状旋钮上设有与其弧度相适应的圆弧形凹槽41，所述圆弧形凹槽41内设有角度刻度线42，从而可以精确控制挡板2需要转动的角度。所述圆弧形凹槽41内还设有手动拨块43，方便转动手动操作旋钮4。所述手动操作旋钮4上还设有可将旋转后的手动操作旋钮4固定的固定装置，所述固定装置为螺栓。
使用时，手动拨动手动拨块43，使得手动操作旋钮4转动，从而可以带动挡板2转动以改变角度，使得挡板2改变空气通道11的大小，从而达到改变进气量的目的，实现空气进气量的定量控制。当挡板2调整到合适的位置后，通过固定装置对手动操作旋钮4进行固定，从而防止阀门开口大小改变。
实施例二
请参考图3，所述的可自由调节空气进气量的阀门包括连接管1，所述连接管的两端分别与比例混合器与空气滤清器密封连接，从而使得阀门整体密封，无漏气现象。所述连接管1的内部是空气通道11，所述空气通道11内设置有挡板2和连接轴3，所述连接轴3的两端贯穿安装在连接管1的管壁上，所述挡板2安装在连接轴3上，所述挡板2的外径与连接管1的内径相同，从而能无缝隙阻隔空气进气。所述连接管1的外部设有步进电机5，所述步进电机5的输出轴通过传动机构6连接至连接轴3的一端，其通过连接轴3联动挡板2，以使挡板在0°-90°范围内旋转以关闭和打开该空气通道11。
具体而言，所述传动机构6可以为减速机61和联轴器62，也可以为蜗轮蜗杆机构，采用蜗轮蜗杆机构可以使得挡板2转动角度控制的更加精确，所述蜗轮蜗杆机构的蜗轮连接连接轴3，所述蜗轮蜗杆机构的蜗杆连接步进电机。
使用时，采用步进电机驱动连接轴3和挡板2转动，可以改变空气通道11的大小，从而达到改变进气量的目的，实现空气进气量的定量控制。步进电机还可以很好的避免阀门开口大小改变。
以上结合最佳实施例对本发明进行了描述，但本发明并不局限于以上揭示的实施例，而应当涵盖各种根据本发明的本质进行的修改、等效组合。
